I am a super cop

Chapter 3010 The Root of the Conflict
While Gu Chen was thinking in the car, his phone suddenly rang. Gu Chen looked at it and saw that the caller was He Junchao.

Gu Chen quickly swiped to answer the call: "Senior Brother He."

"Gu Chen, I discovered from the surveillance footage that Liu Si has returned and is on her way to the rented apartment."

"What did you say?" Gu Chen was stunned for a moment upon hearing He Junchao's words, and quickly asked to confirm:

"You mean, Liu Si, who shares an apartment with Pan Xu and He Lili, is already on her way back to the apartment?"

"Yes, it seems to be only about a 5-minute walk from you," He Junchao said over the phone.

Gu Chen was originally worried about the investigation and had initially suspected Zhao Yanwu, but now it seems that Zhao Yanwu is not the murderer at all.

But now that Liu Si is back, Gu Chen feels he can have a good talk with her.

After all, Liu Si was also someone who had conflicts with the deceased He Lili, and the two were even competitors.

The two also had a falling out over performance issues, and in the end, the company separated their performance records.

This directly led to He Lili's resignation.

But now, He Lili has died from carbon monoxide poisoning, and the day before her death, Liu Si mysteriously left and turned off her phone.

All these suspicious signs gave Gu Chen reason to suspect that the two deaths were related to Liu Si.
But now that Liu Si has returned, Gu Chen feels it's the perfect time.

After hanging up the call with He Junchao, everyone waited quietly in the car.

Shortly after, a ride-hailing car slowly drove into the residential area and stopped directly in front of the building.

After Liu Si got out of the car, she took her luggage directly from the trunk and the ride-hailing car left. As Liu Si was about to go upstairs, she found four police officers standing in front of her.

Upon seeing this, Liu Si was also stunned, somewhat surprised: "Who are you?"

"We are from the Furong Branch of the Jiangnan City Public Security Bureau. Are you Liu Si?" Lu Weiwei asked Liu Si after introducing herself.

Liu Si nodded with a confused look: "Yes, I am Liu Si. What do you need me for?"

“We’ve been trying to contact you, but we can’t reach you no matter what we do,” Officer Wang said.

Liu Si was taken aback, then realized what was happening and quickly explained, "Oh, I've been traveling for a while now, so I turned my phone off."

"So what do you usually use to pay?" Lu Weiwei asked.

“I have another cell phone, which I use to contact my family,” Liu Si said.

"Are you going upstairs now?" Yuan Shasha asked.

"Yes...yes, what's wrong? I live here."

"He Lili and Pan Xu are your roommates, right?" Gu Chen asked.

“Yes, they are my roommates, and they are boyfriend and girlfriend,” Liu Si said.

Seeing the strange looks in Gu Chen's and the others' eyes, Liu Si, also puzzled, quickly asked again:

"No, what happened?"

“Pan Xu and He Lili died from carbon monoxide poisoning,” Gu Chen said.

"What? Carbon monoxide poisoning?" Upon hearing this, Liu Si was stunned. The result seemed too sudden, and Liu Si was not prepared at all.

Seeing this, Gu Chen and the others exchanged glances.

Gu Chen also said earnestly, "The rental house has been sealed off now, and outsiders are not allowed to enter. You also need to cooperate with our investigation."

"But...but how can I cooperate? I...I live here." Liu Si looked completely at a loss upon hearing this.

Gu Chen also reminded him, "We will arrange temporary accommodation for you."

After glancing at Liu Si's suitcase, Gu Chen asked, "What's in here?"

"Oh, it's clothes and some personal items," Liu Si said.

"Can you check it out?" Gu Chen asked.

"Yes...yes." Liu Si was panicked and completely at a loss, not knowing what to do.
As soon as Gu Chen and the others mentioned it, she immediately agreed.

Afterwards, everyone began to inspect Liu Si's suitcase on site. After finding that it only contained some clothes and personal belongings, they put the suitcase back in its original state.

Lu Weiwei picked up Liu Si's suitcase and said, "Let's talk in the car."

"Okay." Liu Si patted his chest, his body trembling.

She then got into the car with Gu Chen and the others, and Lu Weiwei put her suitcase in the trunk of the police car.

After everyone was on the bus, Lu Weiwei set up the camera and then asked:

"Were you and He Lili colleagues before?"

"Yes." Liu Si clasped her hands tightly together, her voice trembling as she answered.

Seeing this, Lu Weiwei comforted her, saying, "Don't be nervous. Just answer whatever we ask you."

"Okay, okay." Although she said it, Liu Si's body was still trembling uncontrollably.

Gu Chen also inquired, "I heard that you and He Lili had a disagreement over work-related matters, and even some conflict. Is that true?"

"Yes...yes." Seeing Gu Chen ask this, Liu Si quickly replied, "But...but it was just some work-related stuff."

"Is it because of performance?" Lu Weiwei asked.

"Yes," Liu Si replied quite quickly.

Officer Wang frowned and continued to ask her, "Weren't you two always on good terms? Why did things turn out like this?"

"I...I don't know either." Faced with Officer Wang's question, Liu Si lowered her head and slowly explained:

“When He Lili first came here, I thought she was pretty good, and the company boss appreciated her, so he assigned her to me to mentor her.”

“At first, she got along quite well with me. Later, I thought that she had just arrived here and hadn’t been able to find a suitable place to rent, so I invited He Lili to move in with me.”

"It just so happens that I'm renting a two-bedroom, two-living-room apartment. Having another roommate means we can split the rent in half, which is not bad."

"Plus, we're colleagues, so commuting to and from get off work is convenient." "And then what happened? Why did you two have a conflict?" Yuan Shasha asked.

"And then?" Liu Si frowned, pondering as she spoke:
"Later, I don't know what happened? Maybe it was because He Lili was too outstanding. She worked for a short time, and her performance started to gradually surpass many of us from last place."

"Later I found out that she was really willing to put aside all pride for the sake of her performance, and she was also very eloquent and had a good appearance."

"Moreover, she is good at getting along with these partners and getting them to do business for her."

Taking a deep breath, Liu Si continued to explain, "So, with the help of several good older brothers, He Lili's performance improved very quickly."

"So, it's because He Lili's performance surpassed yours that you have a problem with her?" Lu Weiwei asked.

But Liu Si remained silent for a while before slowly saying, "You could understand it that way."

"Because He Lili used her various advantages to explore customer channels, she eventually surpassed me in performance and received praise from the company leaders."

“I admit that, gradually, I became a little jealous of He Lili, but she is an excellent salesperson.”

"That's why our relationship gradually changed from a cooperative one to a competitive one."

"Since we both live in the same house, it can be a bit awkward when we're together."

"In addition, during that period, there was a man who was pursuing He Lili, who was the one who brought her sales channel resources."

"But He Lili accepted this ambiguous relationship."

"What do you mean by an ambiguous relationship?" Officer Wang asked, feigning ignorance.

Liu Si quickly explained, "It's the kind of thing where you neither accept nor reject. I think He Lili is a master of romance. She's very good at using men's affection for her to manipulate them into working for her."

"But you should know that He Lili had a boyfriend. At that time, her boyfriend was working in the provincial capital. During the day, He Lili was entangled with that man, and at night she would talk on the phone with her boyfriend until very late."

"And so, she played around with two men, or rather, more men, with ease, which made me feel a little uncomfortable."

Taking a deep breath, Liu Si looked up at everyone and said apologetically:

"I'm sorry, I may have been a bit emotional. I can't stand He Lili's behavior, so I'm becoming more and more disgusted with her character."

"We even had a fight at the company later on. The manager felt that the two of us were not suitable to work together, so he separated the business and let us develop the business separately."

At this point, Liu Si looked distressed: "Later, He Lili's boyfriend, Pan Xu, was also transferred from the provincial capital to work at the branch office here."

"Actually, it's because He Lili keeps telling her boyfriend that someone is harassing her, and that she feels very insecure."

"So her boyfriend was furious and got the head office to transfer him to this branch office."

"But after she moved in with her boyfriend, I really couldn't get used to their lifestyle, so I completely lost any feelings I had for them."

"Then why did you leave for a while?" Lu Weiwei asked curiously as she listened to Liu Si's explanation.

Liu Si slowly said, "Because, because I feel very uncomfortable living with He Lili and her boyfriend Pan Xu."

“Before, because I was a long-time employee in the company, everyone would side with me.”

“But now, He Lili has become a star in the company, which makes it difficult for my relationship with her to go back to what it was before. However, because He Lili’s boyfriend has returned, she can no longer have any connection with the man who used to pursue her.”

"Many of He Lili's achievements were brought to her by this man. If she has nothing to do with him, it means that her performance will also decline sharply."

"In addition, after He Lili's boyfriend came here, he became very controlling of her, so he wouldn't allow her to work at our company anymore, which is why He Lili resigned."

"So you think He Lili resigned because of performance pressure?" Gu Chen asked.

Liu Si nodded silently: "Yes, without that man's help, He Lili's performance would not have been able to return to its previous level."

"With her boyfriend coming over, she had a good excuse to leave the company."

"But as a result, many people in the company thought that Lily's departure was my fault and put the blame on me."

At this point, Liu Si's eyes began to redden, and she said with a wronged expression:

"But what does this have to do with me? Oh, before you used the excuse of making friends with other men to get them to help you get business."

“But now that your boyfriend is here, he forbids you from having any contact with other men, so your performance can’t return to its previous level. Therefore, resigning is the best way to save face.”

“But what does all this have to do with me? It has nothing to do with me. But my colleagues won’t think that way. They will only think that it was because of my jealousy that He Lili resigned.”

After a pause, Liu Si composed herself and continued to complain, "I have no choice. At the company, I have to put up with all kinds of opinions. When I get back to my rented apartment, I have to put up with He Lili and her boyfriend showing affection to each other."

“I had really had enough, so during that period, I was in a bad mood and couldn’t focus on my work.”

"So I went to the hospital to get some medicine, and asked my boss for leave to go on a trip for a while so that I could heal my mood."

"Then why did you turn off your phone during your trip?" Officer Wang asked curiously.

Liu Si sighed and said slowly, "My life has always revolved around work, and work has left me completely overwhelmed. So I want to take this time to rest properly."

“In the past, whenever I had something to do after get off work, my boss would call me non-stop.”

“After get off work, I still have to communicate online in various ways, so to avoid this situation, I turned off my work phone so that my supervisor couldn’t reach me.”

"After all, when I go out to play, I don't want to play during the day and then have to work overtime for my boss at night. That's not the kind of trip I want."

"Okay." Listening to Liu Si's explanation, Gu Chen felt it was understandable, and it was roughly the same as his guess.

Gu Chen then asked Liu Si, "But He Lili and her boyfriend Pan Xu both died of carbon monoxide poisoning. How did that happen?"

"I really didn't know!" Hearing Gu Chen say this, He Lili said aggrievedly, "We usually eat out and rarely use gas at home."

"Is there any gas in the liquefied gas tank?" Lu Weiwei asked.

"Yes, but I rarely use it because I usually go home very late. I usually finish my work outside and have dinner before going home," Liu Si said.

Listening to Liu Si's explanation, Gu Chen also felt that Liu Si didn't seem to have the means to kill them, since Liu Si left the day before the two died.

First, there was no time to commit the crime. Second, there was the issue of gas. To poison Pan Xu and He Lili, a large amount of gas leakage would be required.

However, it's impossible to kill someone with a gas cylinder that hasn't been used recently, because there are no signs of use on the gas cylinder, which is hard to explain.

Thinking of this, Gu Chen noticed that the vehicles of Ding Liang and Huang Zunlong, whom he had called, had also slowly arrived and stopped next to his vehicle.
