Solving the case: Combining the police dog's olfactory genes at the beginning

"Officer, is there a problem?"

"Nothing, just looking around."

Deng Yunzhou waved his hand and walked towards the computer desk equipped with a 47-inch ultrawide monitor.

The PS5 game console was placed next to the monitor, with several stickers of anime characters on it.

"Does Mr. Jiang usually play games?"

"I used to love playing games, but I rarely do it now."

Li Ya's voice came from behind.

"He said he's getting old and his reactions aren't keeping up."

A barely perceptible smile appeared on Deng Yunzhou's lips.

"Can I try it? This monitor looks really cool."

Li Ya hesitated for a moment.

"It should be okay, right?"

"Thanks."

Deng Yunzhou plopped down in the gaming chair and expertly pressed the power button.

Taking advantage of the lull in the system startup, he casually asked.

What types of games does Mr. Jiang like to play?

"It looks like a shooting game?"

Li Ya answered uncertainly.

“I don’t quite understand this.”

The screen lit up, and Deng Yunzhou quickly glanced at the desktop icons while taking a USB drive out of his pocket.

His movements were fluid and effortless, as if he were merely adjusting the seat height, but in reality he had already inserted the USB drive into the port on the back of the host computer.

"This monitor is really awesome."

He typed on the keyboard as he spoke.

"The color reproduction is very high."

Meanwhile, in the living room, Luo Fei was sitting on the sofa, seemingly casually flipping through the photo album on the coffee table.

"Ms. Li, do you and Mr. Jiang usually have the same daily routine?"

He asked without looking up.

Li Ya had just come out of the study when she heard this and was taken aback.

"They're not quite the same. I usually go to bed at ten o'clock, but Jiang Xia has to write at night and often stays up until the early hours of the morning."

Luo Fei nodded.

"Does Mr. Jiang go out in the middle of the night?"

"this."

Li Ya bit her lower lip.

"I'm not quite sure. We only actually sleep together for two or three hours around six or seven in the morning. And I'm a very heavy sleeper; I never get up at night."

Luo Fei closed the photo album and looked directly into her eyes.

How long have you been married?

"Nine years."

Li Ya's expression softened somewhat.

"I met him when I was still a college student; he was already over thirty."

"Has he had a girlfriend before?"

Li Ya's smile froze for a moment.

"There were seven or eight, but none of them worked out."

"What's the reason?"

"Both sides have their problems."

Li Ya avoided Luo Fei's gaze.

"Jiang Xia has a somewhat strange personality, and not everyone can accept it."

Just as Luo Fei was about to press further, a child's laughter came from the next room.

Chen Xuanran was squatting on the ground, fiddling with a remote-controlled car with Jiang Ziqi.

"This car is so cool!"

Chen Xuanran gave a thumbs up.

Did your dad buy it?

Jiang Ziqi didn't even look up.

"Mom bought it."

Li Ya walked over and patted her son's head.

"Some of them were bought by Dad, have you forgotten?"

"Mom bought it!"

Jiang Ziqi suddenly raised his voice, his face turning bright red.

"My dad never buys me toys!"

Li Ya's expression instantly turned awkward.

"Ziqi, don't talk nonsense."

"I'm not talking nonsense!"

The child suddenly stood up, and the toy car fell to the ground with a crisp sound.

"Dad only likes his computer and toys! He doesn't love me at all!"

After saying that, Jiang Ziqi turned and ran out of the room, slamming the door shut behind him.

An awkward silence fell over the living room.

Li Ya forced a smile.

"My child has been in a bad mood lately. Please don't worry about it."

Luo Fei and Chen Xuanran exchanged a glance.

At this moment, Deng Yunzhou came out of the study and gave Luo Fei a barely perceptible nod.

"Ms. Li, we'll take our leave now."

Luo Fei stood up.

"Just rest well at home during this time, and contact us anytime if you need anything."

After leaving Jiangxia's house, as soon as the three of them got into the car, Deng Yunzhou couldn't wait to give a report.

"It's done. The remote monitoring code has been implanted. As long as he uses that computer, we can get all the operation records."

Luo Fei nodded.

"Li Ya also made some progress. Her schedule is completely different from Jiang Xia's. If Jiang Xia goes out in the middle of the night, she won't even know."

"That child."

Chen Xuanran frowned.

“His hostility toward his father was very abnormal.”

"Let's go back to the station first."

Luo Fei started the car.

"Jiang Xia should have been released by now, we need to hurry."

When he returned to the police station's conference room, his colleagues who had been investigating Jiang Xia's ex-girlfriend were already waiting there.

Luo Fei sensed the somber atmosphere as soon as he entered the room.

"Anything discovered?"

he asked directly.

Officer Xiao Wang stood up and opened his notebook.

"Jiang Xia did indeed have seven girlfriends before meeting Li Ya. Six of them are currently living normal lives, but one of them, Zhang Weiwei..."

"what happened?"

"He committed suicide at the beginning of this year."

Xiao Wang's voice lowered.

"On Valentine's Day."

Luo Fei's pupils suddenly contracted.

"Specific time?"

"On the morning of February 14th, he overdosed on sleeping pills. He was already unconscious when he was discovered."

Xiao Wang turned a page.

"It was more than a month earlier than the first victim, Li Changxing, who was killed."

Chen Xuanran gasped.

"Could Zhang Weiwei be the victim of gang rape? Is Jiang Xia avenging her?"

Luo Fei shook his head.

"The timing doesn't match. If Zhang Weiwei committed suicide in February, and Jiang Xia wanted revenge, the first victim should have appeared shortly after that. But Li Changxing's death occurred at the end of March."

"and many more."

Deng Yunzhou suddenly interrupted.

Where does Zhang Weiwei live?

"Near Central Park."

Xiao Wang answered.

"Moreover, according to her friend's description, she likes to play mahjong and often stays out all night."

Luo Fei tapped his fingers lightly on the table.

What is her current relationship status after the breakup?

"I haven't had a boyfriend in seven or eight years, and I don't have a proper job."

Xiao Wang paused for a moment.

"But her standard of living has always been quite high."

There was silence in the conference room.

Everyone realized the weight of this information.

"Jiang Xia is supporting her?"

Chen Xuanran said in a low voice.

Luo Fei looked at the colleague in charge of the financial investigation.

"What is the economic situation in Jiangxia?"

"He and Li Ya are financially independent."

The other person pushed up their glasses.

"Jiang Xia mainly earns income from writing, with monthly royalties of around 30,000 to 40,000 yuan, so he is fully capable of making a living outside."

Luo Fei stood in front of the floor-to-ceiling window in his office, his fingertips lightly tapping the glass, his gaze fixed on the deepening night outside.

His "Genius Eye" had failed. This was the first time he had encountered such a situation. In the past, as long as he concentrated, details that ordinary people overlooked would automatically connect in his mind, pointing to the truth.

But this time, his intuition seemed shrouded in a fog, impossible to penetrate no matter what.

"Captain Luo, Team One and Team Three can't hold on any longer either."

Deng Yunzhou pushed open the door and came in, carrying two cups of coffee. His dark circles under his eyes looked like he had been punched twice.

Luo Fei took the coffee and chuckled softly.

"What did they find out?"

"What else could there be?"

Deng Yunzhou shrugged.

"One team claimed the murderer was a middle-aged man in his thirties, and the third team was similar, but they didn't even manage to find a trace of the suspect."

Luo Fei took a sip of coffee, and the bitter taste spread across his tongue.

"They've fallen for their trap."

He said lightly.

"Fell into a trap?"

Deng Yunzhou was taken aback.

"Jiang Xia set up a trap."

Luo Fei put down his cup, his eyes sharpening.

"He deliberately left some misleading clues to draw the police's attention to a 'killer' who did not exist at all."

Deng Yunzhou gasped.

"Then aren't we being led by the nose by him?"

"So, we need to change our approach."

Luo Fei turned and walked towards the whiteboard, which was covered with photos and clues related to the case.

He picked up a pen and circled the name "Zhang Weiwei".

"First of all, was Zhang Weiwei actually the victim of the gang rape? If so, then the person who killed Zhu Mingwei was very likely related to her death."

Deng Yunzhou frowned.

“But Jiang Xia didn’t have time to commit the crime. He was in the residential area when the incident happened, and the surveillance cameras captured it clearly.”

"So, he might not be the one who directly took action."

Luo Fei narrowed his eyes.

"But he must have been involved in the planning."

Just then, Deng Yunzhou's phone rang.

He glanced down and his expression changed drastically.

"Captain Luo! Jiang Xia's computer is online!"

Luo Fei's eyes sharpened.

"go!"

The two rushed to the network technology department, where the technicians had already retrieved the remote monitoring footage of Jiangxia's computer.

On the screen, Jiang Xia's QQ window was displayed, and he seemed to be discussing the novel's plot with his editor.

"Is he typing?"

Deng Yunzhou was somewhat surprised.

Luo Fei stared at the screen without answering.

Jiang Xia's fingers tapped rapidly on the keyboard, and the text on the Orange Melon Fonts software interface scrolled continuously.

But suddenly, he stopped moving.

"He found out?"

Deng Yunzhou asked nervously.

Luo Fei did not answer, but instead gave the order directly.

"Check his WeChat."

The technician quickly switched the interface, but Jiang Xia's WeChat chat history was clean, with no suspicious content other than his daily conversations with his wife Li Ya.

“Strange,” Deng Yunzhou muttered.

"Is he really just writing novels?"

Luo Fei suddenly raised his hand.

"Wait, restore the previous scene."

The technician did as instructed, but just as the screen switched back, a line of text suddenly appeared on the screen.
Why did you stop watching?

Deng Yunzhou suddenly took a step back, his face turning deathly pale.

"He knew we were monitoring him?!"

Luo Fei laughed.

interesting.

He sat down at the computer and his fingers flew across the keyboard.

"No need. I know you didn't kill the person, but I also know what you've done."

After a brief silence, Jiang Xia replied.
"So what? I hope you won't bother me in such a low way next time."

The next second, the screen went black.

Jiang Xia shut down the computer immediately.

Deng Yunzhou was dumbfounded.

"Is he...is he provoking us?!"

Luo Fei stood up, his eyes filled with excitement.

“That’s interesting.”

Meanwhile, the atmosphere in the offices of Team One and Team Three was so oppressive it was almost suffocating.

Xu Guangwu slammed his fist on the table and cursed angrily.

"Three days have passed! Not a single clue has been found! If this continues, my year-end bonus is completely gone!"

The team members kept their heads down, and no one dared to speak.

Di Yifan sat in the corner, his brows furrowed.

He had just called the "female detective," who stated unequivocally that Jiang Xia was the murderer, but he still felt that something was amiss.

"Captain Di, should we just arrest them?"

One of the team members asked tentatively.

Di Yifan shook his head.

"With insufficient evidence, taking rash action will only alert the enemy."

"If we drag this out any longer, the second team will snatch the case away!"

Di Yifan rubbed his temples, feeling extremely irritated.

Why is he so unlucky? He just had to run into such a tricky case!
"Captain Luo, we've made a new discovery!"

Deng Yunzhou's voice came from the computer screen, and his face, wearing black-rimmed glasses, looked particularly excited during the video call.

"Zhu Mingwei has a female netizen on WeChat named 'A Smile That Can Topple a City,' and their chat content is quite ambiguous."

Luo Fei was holding a bowl of instant noodles when he heard this. He immediately put down his fork and rushed to the computer.

The screen shows a screenshot of a chat history. A pink cartoon avatar, a photo of a collarbone faintly visible in the Moments, and the sentence, "My husband went out for a business dinner again tonight, and I'm all alone at home."

"Damn, that's standard scam rhetoric."

Luo Fei licked the chili oil from the corner of his mouth.

"Check when this woman added him."

Deng Yunzhou's fingers clattered across the keyboard.

"Three months ago, I used the 'People Nearby' feature, but the chat history shows that the other party said 'I added the wrong person'."

He pushed up his glasses.

"The same old trick: first pretend it's a coincidence, then slowly cultivate feelings."

Luo Fei narrowed his eyes.

The chat history on the screen resembled a meticulously crafted script: a lonely young woman, a husband who was never home, and highly suggestive selfies.

Zhu Mingwei, that lecherous scoundrel, became increasingly blatant in his replies, eventually practically begging to meet.

"Wait, the night before the incident."

Luo Fei suddenly pressed down on Deng Yunzhou's mouse.

"Enlarge this section."

23:27 minutes.

"A Smile That Captivates a City" sent a voice call invitation, lasting 4 minutes and 38 seconds. At 23:45 PM, Zhu Mingwei sent a hotel location and a message.

"Honey, I've booked the room."

He died early the next morning.

Luo Fei sneered.

"This is no fucking coincidence."

The small office suddenly fell silent.

The buzzing sound from the air conditioner vents became unusually clear.

Luo Fei felt a chill run down his spine as he recalled the more than twenty knife wounds on Zhu Mingwei's corpse, and the severed genitals lying to one side.

"Check the cell phones of the first two victims."

Luo Fei grabbed his coat.

“I will go to the forensic department in person.”

The metal cabinet in the evidence department emitted a faint smell of desiccant.

Luo Fei put on gloves and carefully took out two cell phones from the evidence bag.

Even after charging and turning on the device, the red dot on the WeChat icon remains glaringly obvious.

"really."

Luo Fei's finger slid across the screen, a cold smile creeping onto his lips. Both phones contained similar contacts.
"Night is Not Yet Over" and "Lonely Rose" share the same pink profile picture, the same "Added the Wrong Person" opening line, and even the lines complaining about their husbands not coming home are exactly the same.

They're active after 10 p.m.

Deng Yunzhou leaned over to take a look.

"Never replies during the day."

Luo Fei suddenly remembered something and looked up sharply.

"Where is Jiang Xia's phone?"

"The data recovery is still being done by the technical department."

Deng Yunzhou shook his head.

"But even if we find similar contacts, it doesn't prove anything. These accounts were definitely registered with fake identities."

Can IP addresses be checked?

Deng Yunzhou sighed, his fingers flying across the keyboard. (End of Chapter)
