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

"what's the situation?"

Luo Fei frowned and turned to look at Chen Xuanran beside him.

"Is there something on my face?"

Chen Xuanran was holding a hairdryer, a slight smile playing on his lips, his eyes gleaming with the satisfaction of a successful prank.

No, it's probably because you're too handsome.

She feigned innocence, but the curve of her lips betrayed her.

Luo Fei narrowed his eyes, looking at her suspiciously.

At this moment, a young girl walked over, blushing, and asked in a low voice.

"Um... could I get your autograph? I... I've seen your work."

"Works? What works?"

Luo Fei was completely confused.

The girl's face turned even redder, and she stammered.

"You know, those kinds of short films."

Luo Fei's expression froze instantly. He turned sharply to Chen Xuanran, whose shoulders were shaking from trying to suppress his laughter.

"Chen Xuanran!"

Luo Fei gritted his teeth.

Chen Xuanran finally couldn't help but laugh out loud.

"Serves you right for hitting on a shampoo girl in front of me!"

Luo Fei suppressed his anger and said in a low voice.

"I did that to investigate a case! Zhang Weiwei's case! And I actually got some information out of her!"

Chen Xuanran's laughter stopped abruptly, and she opened her eyes wide.

"Really?"

"Go out and talk."

Luo Fei glanced at the onlookers who were listening intently, grabbed his coat, and strode out of the hair salon.

Outside, the sunlight was blinding.

Luo Fei put on sunglasses and waited for Chen Xuanran to catch up before speaking.

"That shampoo girl said that Zhang Weiwei was not Jiang Xia's mistress at all."

"Who is that?"

Chen Xuanran dropped his joking expression and became serious.

"Lu Shaochuan of Sihai Group."

Luo Fei uttered the name with a sharp glint in his eyes.

"The finance director is said to be a rich second-generation who's a big spender."

Chen Xuanran gasped.

"Sihai Group? That listed company with a market value of tens of billions?"

"Yes."

Luo Fei nodded.

"So we need to go and meet with this Director Lü."

The headquarters building of Sihai Group soars into the clouds, its glass curtain wall gleaming in the sunlight.

Luo Fei and Chen Xuanran stood in front of the building, looking up at this structure that symbolized wealth and power.

"How impressive!"

Chen Xuanran sighed.

"How much would you need to earn a year working in a place like this?"

Luo Fei gave a soft snort.

"I don't know how much his annual salary is, but I do know that this Director Lü is definitely not short of money to play around with women."

The two entered the spacious and bright lobby and went straight to the front desk.

The receptionist had impeccable makeup and a professional smile.

"Hello, how can I help you?"

Luo Fei showed his police officer ID.

"We would like to meet with Lu Shaochuan, the finance director."

The receptionist's smile froze for a moment, but quickly returned to normal.

"Do you have an appointment?"

"No, but it's a very important matter."

Luo Fei's tone was resolute.

"Tell him it's about Zhang Weiwei."

The receptionist hesitated for a moment, then picked up the phone and whispered a few words.

After hanging up, she said politely.

"Director Lü said I could go directly to his office, which is on the 28th floor. Turn right after exiting the elevator and go all the way to the end."

Inside the elevator, Chen Xuanran asked in a low voice.

Do you think he will cooperate?

Luo Fei's lips curled into a cold smile.

"He has no choice but to cooperate."

The corridor on the 28th floor is covered with thick carpet, completely absorbing the sound of footsteps.

Lu Shaochuan's office was at the very back, with double solid wood doors that spoke of the owner's status.

Luo Fei knocked on the door, and a lazy male voice came from inside.

"Come in."

Pushing open the door, the sight before them both froze for a moment.

The office is over 100 square meters, with floor-to-ceiling windows offering panoramic city views.

On one side was a luxurious office area, while on the other side was a mahogany tea table, where a man in a custom-made suit was leisurely brewing tea.

"Officer, please have a seat."

The man raised his head, revealing a face with sharp features, narrow eyes, and a faint smile at the corners of his mouth.

His gaze lingered on Chen Xuanran for a few seconds, a strange light in his eyes.

Luo Fei keenly noticed this detail, and at the same time, his "Genius Eye" automatically activated, and a string of information appeared above Lü Shaochuan's head.

[Prostitution] [Group sex].

"Director Lü has a refined taste."

Luo Fei sat down without making a sound, and Chen Xuanran sat down next to him as well.

Lu Shaochuan handed over two business cards, with gold-edged lettering and a heavy feel.

"What business do you two officers have with me?"

Luo Fei didn't take the business card; he asked directly.

Do you know Zhang Weiwei?

Lu Shaochuan's hand paused in mid-air for a second before naturally retracting.

"Zhang Weiwei? The name sounds familiar, but I can't quite place it."

Chen Xuanran took out Zhang Weiwei's photo from his bag and pushed it over.

"It was her, she's already dead."

Lu Shaochuan glanced at the photo, his expression unchanged.

"Oh, I think I met you at a party. Sorry, I meet too many people to remember."

Luo Fei sneered.

"Really? Then you must remember the child in her belly, right?"

Lu Shaochuan's expression finally changed.

"What do you mean?"

"I mean."

Luo Fei said, emphasizing each word.

"Zhang Weiwei's death is inextricably linked to you."

"absurd!"

Lu Shaochuan suddenly stood up.

"Is this how you police handle cases? You just arbitrarily slander people? I'm going to file a complaint against you!"

Luo Fei calmly stood up and suddenly kicked Lü Shaochuan in the knee.

Lu Shaochuan cried out in pain and slumped back into his chair.

"The police are beating people!"

Lu Shaochuan shouted, but the heavy office door blocked out the sound.

Luo Fei looked down at him.

"Keep shouting. Let's see if the security guards you call are faster, or if I find those 'little movies' on your computer faster."

Lu Shaochuan's face turned deathly pale instantly.

"What are you saying?"

Luo Fei walked towards the computer behind the desk.

"Group sex, prostitution, and... molesting policewomen and filming it? These charges are enough to put you in jail for several years."

Cold sweat beaded on Lü Shaochuan's forehead as he stared intently at Luo Fei.

"who are you?"

"Luo Fei, a criminal investigator."

Luo Fei turned around, his eyes sharp as knives.

"Now, can we have a proper talk about Zhang Weiwei?"

Lu Shaochuan's arrogance was completely extinguished, and he lowered his head in dejection.

"I'm willing to cooperate."

The lights in the interrogation room were pale.

Lu Shaochuan slumped in his chair, fine beads of sweat appearing on his forehead.

He had just finished explaining his relationship with Zhang Weiwei, and he felt completely drained.

"So, you attacked Zhang Weiwei because she was pregnant?"

Chen Xuanran stared at him coldly, her fingers unconsciously clenching.

Lu Shaochuan twitched the corners of his mouth, revealing an ugly smile.

"Officer, I already told you, I had my vasectomy. How could she possibly be pregnant with my child? That bitch must be cheating on me!"

"Snapped!"

Chen Xuanran suddenly stood up and slapped Lü Shaochuan hard across the face.

"Are you even human?! The forensic report shows that Zhang Weiwei was indeed sexually assaulted before she became pregnant!" Chen Xuanran's eyes were bloodshot.

"She was wronged by you until her death!"

Lu Shaochuan covered his face, his eyes filled with panic, but he quickly reverted to his rogue-like demeanor.

"Ha, who knows if she made it up?"

"enough."

Luo Fei, who had been silent all along, suddenly spoke.

He stood up, his sharp gaze sweeping over Lü Shaochuan.

"Zhang Weiwei said she was raped by someone?"

Yes, that's what she said.

Lu Shaochuan muttered.

Luo Fei frowned.

Something's not right. The surveillance footage clearly shows that multiple people committed the crime. Why would Zhang Weiwei lie?

"take away."

Luo Fei waved to the police officer next to him, then turned and walked out of the interrogation room.

In the corridor, Chen Xuanran caught up with Luo Fei.

"Captain Luo, are we just going to let this beast go like that?"

"No hurries."

Luo Fei sneered.

"The stuff on his computer is enough to give him a hard time."

Inside the police car, Chen Xuanran, holding Lü Shaochuan's laptop, couldn't help but ask.

"Captain Luo, who do you think the murderer is? Jiang Xia?"

"impossible."

Luo Fei shook his head.

“Jiang Xia has long since lost feelings for Zhang Weiwei. He has a wife and children now, so there’s no need for him to take any risks.”

"Who could it be? Does Zhang Weiwei have any other relatives?"

Luo Fei did not answer.

He gazed at the scenery rushing past the window, and the image of Zhang Weiwei's file floated into his mind. What secrets was this girl still hiding?
Back at the police station, Luo Fei immediately convened a meeting with the task force.

"Gentlemen, major progress."

Luo Fei stood in front of the projector.

"It has been confirmed that Zhang Weiwei is the victim of the sexual assault case."

There was an uproar in the conference room.

Cheng Yunchuan quickly retrieved the information.

According to the investigation, Jiang Xia and Zhang Weiwei met through a blind date and their relationship lasted only a short time. After breaking up, Jiang Xia quickly started a relationship with Li Ya.

"Li Ya?"

Luo Fei keenly noticed the name.

"That college student?"

"Yes, she is now Jiang Xia's wife."

Cheng Yunchuan added.

"It is worth noting that Zhang Weiwei had a close colleague named Lin Xiaoyu during her time working at the KTV."

A photo of a pretty girl appeared on the projector.

"Lin Xiaoyu"

Luo Fei muttered to himself.

"Check her background."

The next day, in the forensic room.

Chen Xuanran held the latest test report, his face grave.

"Captain Luo, only one person's DNA was detected in Zhang Weiwei's body."

"what?"

Luo Fei suddenly looked up.

"Wasn't it a case of multiple people committing the crime?"

"The technical department checked it three times and confirmed that there was indeed only one person's biological trace."

Luo Fei slammed his fist against the wall.

Surveillance footage doesn't lie, but evidence doesn't lie either. How does that work?

"Captain Luo!"

Cheng Yunchuan rushed over.

"We found Lin Xiaoyu's information. She resigned two years ago and now works at a welfare home in the south of the city."

"Orphanage?"

A glint of light flashed in Luo Fei's eyes.

"Get the car ready, let's go now."

On the way, Chen Xuanran couldn't help but ask.

"Captain Luo, do you suspect this Lin Xiaoyu?"

"The last person Zhang Weiwei had contact with before her death was her."

Luo Fei said in a deep voice.

"Furthermore, why would she conceal the fact that multiple people were involved in the crime?"

Chengnan Sunshine Welfare Home.

Lin Xiaoyu is teaching children to draw.

Upon seeing the police, she visibly panicked for a moment, but quickly regained her composure.

"Zhang Weiwei? We're colleagues, but not close."

Lin Xiaoyu lowered her head to organize her art supplies.

"She did come to me before the accident, saying she wanted to borrow money."

"How much to borrow?"

Luo Fei stared sharply at her.

"Five, five thousand."

Lin Xiaoyu's voice grew softer and softer.

Luo Fei suddenly closed in.

"Ms. Lin, do you know what the consequences of perjury are? Only one person's DNA was detected in Zhang Weiwei's body!"

"Wow."

Lin Xiaoyu spilled the paint in her hand on the ground, her face turning deathly pale.

I...I don't know what you're talking about.

"Then let me tell you."

Luo Fei spoke slowly and deliberately.

"You're protecting the murderer. Who is it?"

Lin Xiaoyu trembled all over, and tears welled up in her eyes.

"Yes, it was my brother who was drunk. Sister Weiwei was trying to protect the other talented people."

The conference room was filled with smoke. Luo Fei stood in front of the projection screen, tapping his fingers lightly on the table.

The screen displays Jiang Xia's photo and personal information.

"Based on the existing evidence, I believe that Jiang Xia's suspicion can be temporarily ruled out."

Luo Fei's voice was calm and firm.

"Even if Zhang Weiwei confided in him after being sexually assaulted, given Jiang Xia's personality and circumstances, it is unlikely that he would have a motive to kill her."

Cheng Yunchuan straightened up from his seat, the cigarette between his fingers drawing a white line in the air.

"Captain Luo, I have a question. We've been assuming Zhang Weiwei is the victim, but what if she actually betrayed Lü Shaochuan? Could it be that Lü Shaochuan had another man outside, which angered the real killer?"

Luo Fei squinted; he hadn't considered this angle before.

The other officers in the meeting room also began to discuss quietly.

"An interesting hypothesis."

Luo Fei nodded.

"However, we need more evidence. Let's hear about the progress of other people's investigations first."

Deng Yunzhou opened his notebook.

“I was in charge of investigating Zhang Weiwei’s family situation. Her hometown is in Wuzhou, hundreds of miles away. She has an older sister and a younger sister. The younger sister is in college and has a complete alibi; the older sister runs a curtain business in the county town and was out of town buying goods at the time of the incident; her parents are both over sixty years old, her mother has severe arthritis, and her father had a stroke last year and has difficulty moving around. Zhang Weiwei has no other relatives in Jiangcheng.”

Luo Fei turned to Chen Zhiqiang.

"Zhiqiang, how about you over there?"

Chen Zhiqiang pushed up his glasses.

“I investigated Zhang Weiwei’s social connections. She has a close friend named Su Jing, who was her junior high school classmate, and the two are very close. Interestingly, Su Jing is also being kept by a wealthy businessman and lives in a talent apartment in Shaping District.”

"Su Jing."

Luo Fei wrote the name in his notebook and circled it.

"We need to see her."

The Shanxia Square in Shaping District was bustling with people. Luo Fei and Chen Xuanran stood outside a boutique called "Jingyu".

Through the glass window, you can see a tall woman arranging the shelves.

"It's her, Su Jing."

Chen Xuanran said in a low voice.

"Much prettier than in the photos."

Luo Fei nodded.

Su Jing was indeed outstanding in temperament. Her light blue dress made her skin look as white as snow, and her every move exuded an elegance that seemed out of place in this inexpensive boutique.

As I pushed open the door, the wind chimes rang out with a clear, crisp sound.

Su Jing turned around and saw the two policemen. Her eyes flashed with alertness, but she quickly regained her composure.

"Hello, we are from the Jiangcheng Criminal Police Team."

Luo Fei presented his identification.

"I would like to ask you some questions about Zhang Weiwei."

Su Jing's fingers trembled slightly, but her voice remained steady.

"Let's talk in the coffee shop next door; it's not convenient here."

In a corner booth of the coffee shop, Luo Fei activated his "Genius Eye." This was his special ability to solve cases, allowing him to see key information about those involved in the case.

However, Su Jing's head was completely bare, confirming her innocence in the murder. (End of Chapter)
