I am a super cop

Chapter 1652 The collection 15 years ago [Thanks to the leader "The Emperor of the Wild"]

(two in one chapter)
The mysterious black shadow suddenly disappeared, which made Gu Chen and Lu Weiwei confused.

Especially in the pitch-black old community, this made it impossible for the two of them to hunt down.

Outside the intersection is a backstreet and alley. Even though it is almost 11 o'clock in the evening, there are still people coming and going, because there are many old shops in the backstreet and alley, and many nearby residents will choose to play cards here pastime.

Therefore, there are more or less local residents gathered in front of each store.

When Gu Chen walked to the gate of the community, he suddenly saw a familiar figure walking towards him.

Gu Chen narrowed his eyes and found that it was Lao Cao, the doctor who was injured that day, so he stopped in front of him and called out, "Doctor Cao."

"Huh?" Lao Cao didn't seem to have noticed Gu Chen, and was caught off guard by the sudden greeting.

The soles of the feet seemed to have been oiled, and they almost slipped and fell.

"Officer Gu?" After a moment of reaction, the doctor Lao Cao finally recognized Gu Chen, and then saw Lu Weiwei next to Gu Chen, and asked curiously, "Why are you here?"

"us……"

"We're here to do something." Before Lu Weiwei could finish speaking, Gu Chen immediately interrupted.

Judging from the current situation, Gu Chen is not ready to tell him the news of Li Yumei's death.

Lao Cao also nodded silently, and replied with a faint smile: "You still have to do things at night, you policemen are really just like us doctors, you are just like cows and horses, it's hard work."

"Haha, I'm overwhelmed." Gu Chen tried to calm down, and then hurriedly asked him: "By the way, why are you here?"

"Why am I here? It's a good question." Hearing Gu Chen's speech, Lao Cao immediately put on a show, pointing to his cheek and saying:

"Didn't I get beaten into a pig's head last time? Lao Zhou said that I lacked exercise and didn't even have the most basic defensive ability."

"I also complained that if I practiced a little Sanda technique like him, I guess he would not be able to take advantage of it, and urged me to lose weight, so... so I came to a Sanda boxing training gym here according to Lao Zhou's introduction. Get some exercise."

"Is there a Sanda training center near here?" Lu Weiwei was quite curious when she heard it.

But Lao Cao turned around directly, pointed to a place behind and said: "Walk this way until the end, there is a Sanda training gym at the intersection, the venue is quite big, so I signed up here, ready to exercise Body."

Twisting his arm, Lao Cao also smiled and said: "Isn't it just after training, the whole body suddenly stretched out, which is quite comfortable, but I don't know if I will get backache when I wake up tomorrow. ?”

"After all, I haven't participated in sports for a long time. If I suddenly increase the amount of exercise, my body may not be able to adapt."

"So the beads of sweat on your forehead are all from the Sanda training hall?" Gu Chen looked at the beads of sweat on Lao Cao's forehead and asked him curiously.

Lao Cao nodded in agreement: "That's right, after all, I came here late tonight, and it happened that the Sanda training hall closed very late today. I spent all my money, so I practiced in the training hall for a while."

While explaining to Gu Chen and Lu Weiwei, seeing that Gu Chen and Lu Weiwei also looked strange.

Moreover, when he suddenly appeared at the intersection of this community, Lao Cao was also a little puzzled, and hurriedly asked, "Then what are you two doing here?"

"Let's not talk about that for now." Gu Chen didn't want Lao Cao to know about Li Yumei, so he could only change the subject and said, "By the way, you came from there, did you see a person running over mysteriously?"

"Running there mysteriously?" Hearing this, Lao Cao turned his head to look at the alley behind him, and said with a puzzled expression, "I came from there, but I didn't see anything."

"Okay." Knowing that he couldn't ask anything from Lao Cao, Gu Chen changed his mind and said, "Then how are you going to go home? I remember that your home should be quite far from here, so you are going to walk back?"

"It's quite far." Lao Cao wiped the sweat from his forehead, and said with a smile, "Isn't this the first day I've come here today, so I'm not very familiar with the roads here."

"Especially there are many old neighborhoods here, and the various intersections made me a little dizzy, and I don't know if this small alley can be passed. After all, it is very narrow, so I parked the car at the intersection over there and walked over. , now going to walk back, and then drive home."

"Okay." Gu Chen kept these in mind, nodded silently, gave up his position and said: "Then you go slowly."

"You should also pay attention to go to bed early. It's not good to stay up late and work." Lao Cao smiled perfunctorily, then put his hands on his back and continued to walk towards the end of the alley.

Seeing that Lao Cao's figure was gradually disappearing, Lu Weiwei approached Gu Chen and reminded him, "Could that black shadow you say be Lao Cao?"

"Not sure." Gu Chen shook his head.

Lu Weiwei said again: "I think it's too coincidental for him to come here, and he walked from the other side of the alley, does he have to sweat all over his head? Doesn't he wipe his sweat after exercising? I suspect that he was chased by us, and then He pretended to turn back and deliberately meet us face to face."

"It's possible." Gu Chen sighed, and could only take this as a possible option.

But the black shadow did disappear suddenly on this road, and that mysterious black shadow was Lao Cao?Gu Chen has no proof yet.

The key point is that the lights in the entire alley are extremely dim, which brings trouble to Gu Chen's investigation.

Looking down at the time, Gu Chen reminded, "It's getting late, let's go to the Technical Section of the Municipal Bureau to check on Li Yumei's autopsy, and then go back to the Furong Branch to see if Zhuang Ting and Xu Xiaoli have been taken away." come over."

Gu Chen is also in a dilemma now.

You know, Li Yumei's sudden poisoning, and Li Dong's being transferred from the mountain by a card task, it can be seen that the murderer is targeting Li Yumei, and even the poison has been prepared.

It seemed that everything was being manipulated by the black hand behind the scenes.

Gu Chen doesn't care too much now, knowing that it's very difficult to find the shadow at night.

Instead of wasting time here, it is better to go to see Li Yumei's autopsy.

……

……

11:40pm.

In the testing room of the Technical Department of the Municipal Bureau, Gao Chuanfeng was doing the final matching and verification of Li Yumei's vomit and the toxins in her body.

Gu Chen, Lu Weiwei, Police Officer Wang and Yuan Shasha sat quietly aside.

Running back and forth makes everyone physically and mentally exhausted.

Fortunately, everyone just needs to sit here and wait for the result quietly.

After the test was completed, a forensic assistant drew on the form and then gave it to Gao Chuanfeng.

Gao Chuanfeng was also in front of the instrument, making the final confirmation, and then completed the autopsy report form, turned to look at Gu Chen and said:

"Gu Chen, the test results are back."

"What's the situation?" Hearing this, Gu Chen quickly raised his head and asked him.

"It's poisonous ginseng." Gao Chuanfeng said.

"Poisonous ginseng?" Hearing Gao Chuanfeng's remarks, Gu Chen immediately stood up and said, "You mean, the poison Li Yumei took was poisonous ginseng?"

"That's right." Gao Chuanfeng picked up the test report on the table, stood up, walked up to Gu Chen, then handed the report to Gu Chen and said:
"After testing Li Yumei's vomit and the substances in her body, we found that both the vomit and the substances in her body contained poisonous ginseng."

"What the hell is this stuff? Is it so poisonous? Is it because of the word 'poison'?" Lu Weiwei didn't know much about it, but just by the name, she knew it was poisonous.

Gu Chen took a deep breath and said, "Poisonous ginseng, also called celery leaf hook kiss, is a plant belonging to the Dicotyledonous class, Umbelliferae, Umbelliferae family, and the poisonous ginseng genus."

"Moreover, the whole plant is poisonous, and the fruit, especially the seeds, are the most poisonous."

Looking at the report in his hand, Gu Chen continued to explain: "However, such things are generally distributed in Europe, North Africa, North America, Asia, and the northwest of our country."

"And it usually grows at an altitude of 600 meters to 1700 meters, and often grows on the edge of the forest or the edge of the farmland. We don't have this kind of plant in the south."

"Then why did you come here?" Police Officer Wang came over and leaned over to Gu Chen to read the report.

Gu Chen directly handed the report to Police Officer Wang, and said involuntarily: "Speaking of poisonous ginseng, there are quite a few scientific names for this thing, such as deadly poisonous ginseng, poisonous celery and snake grass."

"There is also a kind of poisonous ginseng, whose scientific name is generally called madweed, cow poisonous grass or beaver poisonous grass."

"And the whole plants of both plants are poisonous, and the younger plants may be more poisonous than the mature plants."

"If a person has symptoms of poisoning, they will appear within 20 to 60 minutes, including stomach pain, nausea, vomiting, diarrhea, dilated pupils, foaming at the mouth, weak pulse, difficulty breathing, muscle weakness, and convulsions. Li Yumei obviously All of these characteristics."

"That's right." Listening to Gu Chen's explanation, Gao Chuanfeng also echoed: "In this case, muscle paralysis often occurs and artificial respiration is necessary, so the victim often suffocates to death due to respiratory system failure. "

"But after being poisoned, it takes a long time to die, so there will be gaps in the middle."

"I see." After hearing Gao Chuanfeng's supplement, Gu Chen's eyes suddenly lit up, and he turned to everyone and said, "I know that the murderer has been staying near Li Yumei's house, because if we count according to the time when Li Yumei died of poisoning."

"Even if she is poisoned, she cannot die in a short time. It takes 20 to 60 minutes for the symptoms of poisoning to appear."

"And Li Dong left at 7:10 p.m. and returned home around 10 p.m. During this period, Li Yumei was left unattended for nearly three hours."

After a pause, Gu Chen tried to adjust his thinking, and continued to add: "And if it takes 20 to 60 minutes for the onset of poisoning, but after being poisoned, you won't die immediately, at least it will take a few hours."

"And if these conditions are met, the murderer must give Li Yumei poisonous ginseng after 7:10 p.m., that is, a short time after Li Dong left Li Yumei's house, so that Li Yumei was poisoned and died before Li Dong returned home. "

"Eh?" Hearing what Gu Chen said, Lu Weiwei suddenly realized, and quickly added:
"Junior Brother Gu, if you don't remind me, I forgot. Li Dong said that he found Li Yumei dead after returning home, and then dialed our phone number."

"And our autopsy also found that the time of death was indeed around the time Li Dong returned home."

"This shows that as soon as Li Donggang returned home, Li Yumei was also poisoned and died. The difference between before and after would not be too long."

"And according to the poisoning process and time you just mentioned, the murderer must have completed the poisoning in a very short time after 7:10 p.m., so the murderer was probably hiding near the corridor, waiting for Li Dong leave."

After the voice fell, the scene suddenly fell silent.

Everyone knew very well that Lu Weiwei was right.

The murderer's cunning is cunning, and Li Dong can be counted to leave.

Gu Chen also had a headache. In order to complete the task assigned by the manipulator behind the scenes, this guy actually threw his aunt aside.

Originally, Gu Chen had hoped for Li Dong, hoping that he could get some clues from his aunt Li Yumei.

But now it seems that this is not the case at all.

But thinking that it is difficult for ordinary people to get poisonous ginseng, maybe there will be some in pharmacies, so Gu Chen can only start here when he thinks about it.

After returning, they mobilized personnel and went to pharmacies one by one to investigate and try to find out the whereabouts of the poisonous ginseng.

Seeing that Police Officer Wang had almost read the autopsy report, Gu Chen took out his cell phone and dialed Huang Zunlong directly.

Not long after, the call was connected. When he learned that the two women, Zhuang Ting and Xu Xiaoli, had been brought back to the police station, Gu Chen hung up the phone and decisively reminded: "Those two women have been taken back to the police station. Go right away."

"Okay." Officer Wang nodded, and directly signaled everyone to follow Gu Chen.

Gu Chen also exchanged a few words with Gao Chuanfeng, then hurriedly left the testing room and drove straight to the Furong branch.

15 am at night.

When Gu Chen and the others hurried to the No. [-] interrogation room, the tall and thin woman Zhuang Ting was already there.

And her companion Xu Xiaoli is also next door.

Gu Chen had to interrogate the two of them separately, so he asked Yuan Shasha to adjust the camera, and sat there directly to get straight to the point: "Zhuang Ting, we meet again."

"Yeah, we met at Li Yumei's house. I was the one who opened the door for you, but..."

After hesitating for a few seconds, Zhuang Ting was a little puzzled and said, "It's just this big night, what are you guys trying to do by bringing me here?"

"Li Yumei is dead." Lu Weiwei said.

"What... what? Li Yumei is dead?"

Hearing Lu Weiwei's remarks, Zhuang Ting was obviously taken aback.

Suddenly with a surprised look in his eyes, he seemed to be in disbelief at all, and asked weakly, "When did it happen?"

"It's around 10 o'clock tonight." Gu Chen said.

"Could it be that he died of illness? No, we were fine when we left, why did we suddenly..."

Zhuang Ting didn't seem to understand, but thinking that it was Li Yumei's nephew Li Dong who sent her away, Zhuang Ting's eyes lit up suddenly, and she quickly said, "I see, it must not have died of illness, right? Could it be Li Dong?"

"It's the police reported by Li Dong." Officer Wang reminded.

Zhuang Ting was stunned, and then said: "He called the police? But we have been taking care of Li Yumei all the time, why did he die as soon as he took care of her? This... What is going on? What did he do to his aunt? what?"

"Quiet."

Seeing Zhuang Ting getting emotional, Gu Chen also reminded her.

But Zhuang Ting didn't listen, and asked Gu Chen in a daze: "Officer Gu, what do you think is going on? How does Li Dong take care of others? There must be an explanation for this?"

"We already have a detailed record of what he said." Gu Chen turned the pen with his right hand, fixed his eyes on Zhuang Ting in front of him, and continued to ask her:

"But there is one more thing I don't know very well. You are not actually Li Yumei's niece, right?"

"what?"

Being suddenly exposed by Gu Chen, Zhuang Ting subconsciously froze for a moment.

But Gu Chen continued to ask: "Not only are you not Li Yumei's niece, Xu Xiaoli is not, including the group of people staying at Li Yumei's house, none of them are Li Yumei's relatives, am I right?"

It seems that the police have the specific information of everyone, and Zhuang Ting's eyes are also blank, which is unimaginable.

After all, it would be very difficult for the police to investigate the details of so many people without using big data.

But in such a short period of time, everyone's identities were revealed. It is obvious that the police are very efficient in investigating the case.

This made Zhuang Ting, who had always regarded herself as Li Yumei's niece, at a loss for a while.

Seeing that Zhuang Ting had become mute at the moment, Lu Weiwei also knocked on the table to remind her, "I'm asking you something? Isn't it?"

"Yes... yes." Zhuang Ting was a little ashamed and could only lower her head silently.

Lu Weiwei shook her head, and asked her curiously, "You said that you are not related to Li Yumei, why do you take care of Li Yumei? So many people come all at once?"

Zhuang Ting bowed her head and remained silent.

Lu Weiwei added: "And we also found out that all of you have criminal records, and most of you have been in prison, including you, Zhuang Ting."

"But what does that mean?" Zhuang Ting asked with her head bowed as she listened to Lu Weiwei's words.

Lu Weiwei said indifferently: "That's right, this doesn't mean anything. If two people with previous convictions get together, I won't say anything, and there is no discrimination in this regard."

"But suddenly more than a dozen people with previous convictions gathered at Li Yumei's house, and these people are not Li Yumei's relatives, but they call themselves Li Yumei's 'relatives and friends'."

"And you and Xu Xiaoli are still living at Li Yumei's house, taking care of Li Yumei day and night, what do you think you are planning?"

The voice fell, and the scene was silent.

Zhuang Ting also seemed to be questioned to the depths of her soul.

At this moment, the police seem to know the details of themselves and their companions well.

Originally, few people outside knew about his criminal record, including those gathered at Li Yumei's house. Everyone had a criminal record, and no one knew about it.

But now the police are digging out these things without reservation.

On the one hand, Zhuang Ting was very angry and felt discriminated against.

But on the other hand, Zhuang Ting was also very timid. She was afraid that the police would investigate everyone's situation clearly in a short period of time.

This is also a side reaction, these policemen are not easy to mess with.

"What else do you want to say?" Seeing that Zhuang Ting was still standing there in a daze, Gu Chen also reminded her.

Feeling that there is no need to hide the matter now, Zhuang Ting sighed and said helplessly:

"You may not believe me when I tell you. Xu Xiaoli and I have been doing business together before. We also do business with Li Yumei's unit. Li Yumei even became a shareholder of our business."

"I know this." Gu Chen already understood, and reminded him: "You get to the point."

"Okay." Hearing Gu Chen's words, Zhuang Ting was also shocked.

Unexpectedly, the police knew all this.

But thinking about Li Dong, Zhuang Ting suddenly felt relieved, and Li Dong must have confessed.

Thinking that Gu Chen wanted to listen to the key points, Zhuang Ting had no choice but to tell the truth: "We are partners with Li Yumei, so the relationship is naturally very good. Logically speaking, Li Yumei was hospitalized after surgery, which doesn't concern us."

"But one day, we suddenly received a white card, this white card..."

"What did you say?"

Before Zhuang Ting finished speaking, Lu Weiwei was stunned and said, "You said you received a white card? Is it a white card with tasks on it?"

"You... how do you know?"

Hearing Lu Weiwei's words, Zhuang Ting was also stunned, feeling as if she had seen hell, as if she had lost even the last bit of privacy.

Lu Weiwei glanced at Gu Chen beside him, and Gu Chen explained directly: "You don't have to be surprised, because Li Dong has received a similar white card before, so your card is also a task, right?"

"Yes." Faced with Gu Chen's question, Zhuang Ting was completely panicked now.

But it was discovered that Li Dong was also the one who accepted the game task, which made it difficult for Zhuang Ting to accept, and even had lingering fears.

"Keep talking." Gu Chen recorded these and continued to ask questions.

Zhuang Ting nodded silently, but was also dumbfounded and said: "Xu Xiaoli and I felt very strange at the time, because before that, we were often entangled in some troubles."

"Sometimes I wake up with a dead cat hanging from the doorknob."

"Sometimes when you're walking on the road, flower pots will suddenly fall from the sky and land next to you. There are also all kinds of weird things, such as a flat tire. After checking, it turns out that the tire was punctured by someone."

Taking a deep breath, Zhuang Ting covered her face with her hands, trying to calm herself down, and then said, "I don't know what's wrong? Who is playing a prank?"

"But until one day, a mysterious white card was clipped on my car window. At first I thought it was an ordinary small advertising card."

"But when I walked in and took a look, I found that the card was bare, but there was a task reminder written on the back, saying that I should go to the vegetable market to take care of an old man's business, spend 100 yuan, buy her vegetables, and return the money to me When ready, hide inside the tire of the vehicle."

Hearing Zhuang Ting's remarks, Gu Chen and his colleagues looked at each other in blank dismay, a little surprised.

Because this is almost exactly the same as Li Dong's experience, and even the troubles that Zhuang Ting encountered are the same.

But just when Zhuang Ting was about to continue explaining, Lu Weiwei took the lead and said, "And the second task, is it asking you to go outside a certain shopping mall and take care of an old man's barbecue business?"

"Then I gave you 90 yuan to take care of the barbecue stall business for 3 consecutive days, and you can only spend 30 yuan each time, right?"

Listening to Lu Weiwei's explanation, Zhuang Ting was dumbfounded.

It felt like Lu Weiwei had magical eyes, and she could clearly understand what she was doing.

This completely overturned Zhuang Ting's previous cognition.

"you……"

Zhuang Ting couldn't sit still.

Seeing this, Gu Chen quickly comforted her and said, "You don't have to be surprised, how did we know? Because Li Dong also encountered the same difficulties as you."

"It can be said that the first two tasks, the manipulator behind the scenes, almost arranged the same tasks as Li Dong, but what is the third task? Take care of Li Yumei?"

Gu Chen casually guessed and said.

At this time, Zhuang Ting was already trembling with fright, feeling that she was a transparent person.

But when Gu Chen asked, he had to say something, so he could only nod in response: "You are right, the third card task is to take care of Li Yumei."

"I didn't agree at first. I felt that the first two tasks were barely acceptable, so I thought it was someone playing a prank."

"But when we didn't go to help take care of Li Yumei according to the agreed time, I opened the door one day and went out, only to find a bag of bloody animal offal hanging on the doorknob of my house."

Having said this, Zhuang Ting directly covered her mouth, showing symptoms of vomiting.

It seemed that thinking of these bloody animal viscera made Zhuang Ting feel a little nauseous.

"It's still the same." Lu Weiwei was dumbfounded, and also looked at Gu Chen: "Even the threats are exactly the same. Can the manipulator behind the scenes be able to understand people's psychology?"

"Did Li Dong also receive animal viscera?" Zhuang Ting said, clutching her stomach.

Gu Chen sighed and nodded silently: "That's right, what happened to you is exactly the same."

"Well, this man is really cruel." Zhuang Ting patted her chest, trying to adjust her breathing, and then said: "After receiving that bag of bloody animal internal organs, I can't stand it anymore, and I feel that I will be killed by that person at any time." Get rid of it."

"Besides, I don't know who that person is? Why do you torture me like this? I have no choice but to obey, and Xu Xiaoli and I started to live in Li Yumei's house and take care of Li Yumei's daily life."

Hearing Zhuang Ting's words, Gu Chen sat up straight suddenly, his eyes were bright, and he asked her seriously: "Tell me the truth, did Li Yumei recover well after she was discharged from the hospital?"

"Yes." Zhuang Ting nodded.

"Then Li Yumei became what she is today, is it your 'masterpiece'?" Gu Chen asked again.

But this time, Zhuang Ting hesitated.

But Gu Chen also clearly saw the answer from Zhuang Ting's micro-expression.

After several seconds of hesitation, Zhuang Ting reluctantly nodded her head in acquiescence.

"Sure enough, you guys did it?" Seeing Zhuang Ting voluntarily admitting it, Lu Weiwei said angrily:

"So Li Yumei's body is getting worse day by day, and she has become like this. All of this is thanks to you?"

"We don't want to either, but we are afraid of that mysterious man." Zhuang Ting explained with tears in her eyes:

"Since we started taking care of Li Yumei, we have often received white cards and even received some medicines, including...including..."

In the middle of speaking, Zhuang Ting suddenly couldn't continue.

Police Officer Wang was a little impatient, and said in a bad mood: "What is included? Can you speak completely?"

Zhuang Ting lowered her head, feeling too ashamed, and took the initiative to explain: "Including what Police Officer Gu said in the room that day, the drugs that may cause Li Yumei's physical condition, what you said is absolutely right, almost everything is right."

"That's why Xu Xiaoli panicked that day. She felt that you were a bit powerful and knew some medical skills, so she pretended to be calm and humbly asked you for advice on Li Yumei's physical condition, in order to dispel your doubts about us."

"So you gave Li Yumei medicine?" Gu Chen frowned and asked.

Zhuang Ting nodded silently: "In the past few months, I have been following the request of that mysterious person. I don't know why that person tortured us like this? Tortured Li Yumei?"

"I'm terrified, and Xu Xiaoli is also terrified, but those medicines often appear in front of our eyes the day Li Yumei finishes taking them. It feels like that person has already calculated the dose and is always ready to deliver it to us."

With a faint sigh, Zhuang Ting also covered her cheeks, and said angrily: "So, just like this, we gave Li Yumei medicine to make Li Yumei's body deteriorate day by day, which directly led to subsequent stroke, paraplegia and aphasia."

"Seeing that Li Yumei has become a puppet and can't take care of herself at all, we feel guilty, but suddenly one day, many vehicles stopped downstairs, that is, the group of people you saw in the living room of Li Yumei's house also came to knock on the door .”

"What are they here for?" Gu Chen recorded these, and raised his head to ask Zhuang Ting.

Zhuang Ting said listlessly: "They also received a reminder from the card and came to gather, saying that they want to settle accounts with the hospital and stand up for Li Yumei."

"And after talking with each other, we realized that everyone is the same. At that moment, we were all dumbfounded."

"Is there such a thing?" After listening to Zhuang Ting's explanation, Yuan Shasha became a little uneasy, and also complained:
"Are you all willing to be the marionettes of this behind-the-scenes manipulator? What's going on with you?"

"I don't know what's going on?" Zhuang Ting cried, her whole body was depressed, and she also lay on the interrogation chair and cried:
"Everyone is threatened, and some of them are not just like what we encountered. There are also those who have received severed fingers from animals, and various dissected animal corpses. Anyway, everyone panicked and felt that the other party was a pervert."

"But due to the threat of the other party and the cherishment of our own lives, everyone gradually got together to complete the manipulator game and accept this weird task for the sake of saving their lives."

"What on earth does he want to do?" Gu Chen frowned, feeling a little unbelievable.

Are these people really accepting the mission because they are afraid of death?

At first Gu Chen didn't believe it, but later he gradually realized that Li Dong would rather complete the task by himself than call the police.

The mysterious behind-the-scenes manipulator has already tortured the psychology of this group of people.

But if you are a straightforward person, why should you be afraid of these things?

But thinking about it again, this group of people all have criminal records, maybe this is their weakness?
But if this is the case, then what happened to Li Dong?Did Li Dong have a criminal record before?
Gu Chen felt that after going back, he still needed to investigate Li Dong again.

During the subsequent interrogation of Zhuang Ting, Gu Chen learned that the original several medical troubles were all instigated by the manipulator behind the scenes.

Everyone actually doesn't know what the purpose of doing this is?But the group participated in it twice.

Gu Chen especially didn't understand, the murderer could easily kill Li Yumei, but why did he make these people go through so much trouble?

Is there another secret?
At least for now, Gu Chen is still unclear.

But when Gu Chen thought according to his own way of thinking, he came to the conclusion that the manipulator might want to treat these people as his pawns, ordering them to do anything at will.

As for Li Yumei, insisting on making her take the medicine and torturing Li Yumei to such a bad shape, maybe this is the biggest idea of ​​the manipulator behind the scenes?
After all, among these people, Li Yumei is the worst one, maybe she also has some relationship with the manipulator behind the scenes?

After the interrogation work, Gu Chen's team questioned Xu Xiaoli in the second interrogation room next door.

The results that can be obtained are basically the same as what Zhuang Ting explained, and all the explanations are very consistent.

This made Gu Chen feel that things seemed to be getting weirder and weirder.

……

……

In the early morning of the next day, when the sun was just rising, Gu Chen led everyone to get busy.

When the interrogation work ended last night, it was already 2 o'clock in the morning.

And everyone started to go to work early at 7 o'clock in the morning, except for washing face, brushing teeth and eating, and slept for more than 4 hours.

He Junchao is the worst one among them, and he has the worst panda eyes.

As soon as Gu Chen came, he would trouble He Junchao, which made He Junchao miserable.

And last night, the black shadow that Gu Chen was following also disappeared, which required He Junchao to give full play to his ability to find out who the mysterious person was.

However, there is no monitoring in the old community, which makes He Junchao quite a headache.

At first, Gu Chen suspected that the black shadow was the doctor Lao Cao. After all, the time to see Lao Cao was just right, when the shadow disappeared.

Moreover, there are still beads of sweat on Lao Cao's forehead, obviously after strenuous exercise.

And that night, I and Lu Weiwei chased the black shadow, which was exciting enough. If ordinary people were chased so frantically, it would be reasonable for ordinary people to sweat and be a little out of breath.

What's more, Li Yumei died of poisoning caused by taking poisonous ginseng, and the medicine she took before caused her body to deteriorate.

Obviously, all of these require certain medical knowledge, and Lao Cao happens to be a senior doctor, so he meets these conditions very well.

However, after passing He Junchao's investigation, Gu Chen resolutely gave up his doubts about Lao Cao.

Because there is no surveillance in the alley, but there is at the entrance of the fitness club.

Gu Chen calculated the time through the monitoring at the entrance of the Sanda fitness club. Lao Cao did come out of the fitness club at the right time, and then walked towards the alley.

And this time happened to be the time when Gu Chen saw the dark shadow in the crowd.

Unless Lao Cao has the ability to clone himself, it is absolutely impossible for him to appear at the scene of the crime to watch, and he has absolutely no idea what happened at the scene, nor can he calculate the time when the police will arrive.

Everything seems to rule out the suspicion of Lao Cao, all of which can only be explained by coincidence.

Putting aside these scattered things, Gu Chen checked everyone's information again, hoping to find some clues from this group of people.

After all, all of these guys with previous convictions received white cards.

Gu Chen believed that the murderer would definitely not be chosen randomly, otherwise these people would not all have previous convictions.

But if you think about it carefully, there may still be some connections among these people.

Thinking of this, Gu Chen began to nail all the personal information files of these people on the whiteboard with colored magnets, and began to conduct a unified analysis of everyone's situation.

After a quick round of reading, Gu Chen found out the first similarity, that is, none of these people are natives of Jiangnan City.

Most of them came from Haidong City, some from Jiangbei, Southwest, and neighboring counties and cities.

But if these people come from all over the world, how did the murderer bring them together?

Based on this idea, Gu Chen conducted a second round of screening, but suddenly discovered that the last person who came to Jiangnan City was half a year ago.

As for the others, although their household registrations are not in Jiangnan City, they have all stayed in Jiangnan City for a long time.

During this period, everyone was working in Jiangnan City, which made Gu Chen very curious.

So the third round of investigation was continued.

This time, Gu Chen was more careful than ever, starting from the first time these people were imprisoned, using the timeline to find the so-called common ground.

After careful investigation, Gu Chen has been sketching on the draft paper for a long time, but suddenly found that most of the people had the experience of staying in Haidong City in May 15 years ago.

Gu Chen seemed to have found something, and quickly began to summarize the timeline of the remaining personnel.

Since he found the similarities between these people, Gu Chen didn't look at other information, and directly checked the other people according to May 15 years ago.

Although there is no record of this time in the information records of some people, among the dozen or so people, six or seven people have stayed in Haidong City at the same time.

This made Gu Chen suddenly feel that maybe these people had stayed in Haidong City for a while in May 15 years ago.

And because these people were either habitual theft criminals or robbery habitual criminals, a large number of these people gathered in Haidong City, and Gu Chen felt that things were not simple.

So he took the draft of the investigation, came back to the desk, and began to use the computer to search for the news information of Haidong City in May 15 years ago.

顾晨利用最笨的方法，直接搜寻海东市15年前从5月1号到5月31号的相关词条。

Soon, a piece of fire news came into view, and Gu Chen even started to read it:
"On May 5, a fire broke out in a residential building in Donggao Town, Haidong City, killing two people. Afterwards investigation found that the dead were a mother and a child..."

Gu Chen continued to look through other information, and the news introductions were basically similar, but no matter how Gu Chen checked, the cause of the fire was only explained as improper use of fire, which was a relatively general investigation.

Throughout May, it seemed that only this news made Gu Chen feel a little confused, but he was not sure.

"Junior Brother Gu, what are you thinking?" Seeing Gu Chen fiddling in front of the whiteboard for a long time and making various inquiries on the computer, Lu Weiwei looked at Gu Chen curiously, feeling that Gu Chen must have found a problem.

Gu Chen didn't hide it, and told Lu Weiwei directly: "I found a problem, that is, this group of people, although they come from all over the world, it's very strange, they all visited Haidong City in May 15 years ago."

"Have you all been to Haidong City?" Lu Weiwei immediately regained her spirits when she heard that, and quickly reminded Gu Chen, "So, this group of people gathered on a large scale 15 years ago?"

"Yes." Gu Chen nodded to confirm, and continued: "And I checked the news in Haidong City in May 15 years ago. Except for a bizarre fire, there seems to be no other news."

After a pause, Gu Chen said again: "So, I want to go to Haidong City to see if I can find some useful clues there."
