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

"This is unbelievable! How could he know so much detail?" His voice was already trembling with emotion.

"Qiao Aiguo".

Luo Fei's voice suddenly softened.

Do you know how many years you can be sentenced for harboring a criminal? Especially when it involves such a large sum of money.

"I did not cover it up!"

Qiao Aiguo suddenly became excited.

"I just"

"Just what?"

Luo Fei pressed his advantage.

"You just received 20 million, then falsified accounts according to Liu Haotian's instructions, and then turned yourself in to take the blame? You think you can get away with it like that?"

Huang Xiao gasped.

"Twenty million?! Captain Luo, this..."

Luo Fei waved his hand, signaling Huang Xiao not to interrupt, and continued to keep an eye on Qiao Aiguo.

"How much money did Liu Haotian promise you for treatment? Cancer treatment isn't cheap, especially for your mother's rare disease."

Qiao Aiguo suddenly looked up, his eyes filled with shock and fear.

The thought, "How could he know my mother was sick?" had barely crossed his mind when he suddenly realized something and tightly closed his eyes.

Does closing your eyes help?

Luo Fei scoffed.

"You think I won't know what you're thinking just because you close your eyes?"

Qiao Aiguo kept his eyes tightly closed, but Luo Fei could hear that his inner defenses were crumbling.

[It's over. It's all over. Liu Haotian said this was absolutely safe.]

The interrogation room fell into a brief silence, broken only by the hum of the air conditioner and Qiao Aiguo's heavy breathing.

Luo Fei calmly twirled the pen in his hand, putting psychological pressure on Qiao Aiguo.

Finally, Qiao Aiguo opened his eyes, his gaze no longer showing the stubbornness he had shown before.

"Officer, if I cooperate, can I get a reduced sentence?"

Luo Fei and Huang Xiao exchanged a glance.

Huang Xiao immediately understood and opened his notebook to take notes.

"That depends on how well you cooperate."

Luo Fei leaned back.

"Tell me first, how was that 20 million in cash handed over to you?"

Qiao Aiguo.

"It was done via a black van. I didn't know the driver. He drove to an abandoned factory in the suburbs and told me to move the money myself."

"Specific time?"

"Around 9 p.m. on the 18th of last month."

Luo Fei nodded; this detail matched what he had gleaned from Qiao Aiguo's thoughts.

Why did Liu Haotian give you so much money?

Qiao Aiguo lowered his head.

"Because...because the group has a funding shortfall of 200 million. The accounts don't match, and someone needs to take the blame."

"So you willingly became this scapegoat?"

Luo Fei raised an eyebrow.

"My mother needs money for surgery."

Qiao Aiguo's voice grew softer and softer.

"Liu Haotian promised that as long as I plead guilty, he would cover all my mother's medical expenses and give me an additional 20 million yuan."

Huang Xiao couldn't help but interject.

"You really trust him that much? What if he denies everything once you're in jail?"

Qiao Aiguo gave a wry smile.

He gave me a five million yuan deposit. He said he would pay the rest after I was sentenced.

Luo Fei sneered.

"Wait until you're sentenced? Qiao Aiguo, you're being far too naive. Once you're in prison, he has a million ways to shut you up."

Qiao Aiguo's expression grew even uglier; clearly, he too was beginning to doubt Liu Haotian's promise.

"Let's talk about the accounts."

Luo Fei changed the subject.

"Where did Liu Haotian misappropriate those two hundred million yuan?"

"I...I'm not quite sure."

Qiao Aiguo's eyes flickered.

"I've only heard that it's an investment in an overseas project."

[It looks like a casino in Macau] Luo Fei caught this crucial piece of information.

"Macau casinos?"

Luo Fei suddenly asked.

Qiao Aiguo froze on the spot as if struck by lightning.

"How could you..."

"how could I know?"

Luo Fei sneered.

"Do you think the police are just sitting around doing nothing? Liu Haotian has been laundering money in Macau for quite some time now."

Huang Xiao looked at Luo Fei in surprise, clearly not understanding why his captain had suddenly brought up Macau.

However, his professional ethics prevented him from questioning it on the spot; instead, he silently noted down the information.

The interrogation lasted for another two hours.

With Luo Fei's precise mind-reading ability, Qiao Aiguo was forced into a series of defeats and revealed more and more details.

By the end of the interrogation, Qiao Aiguo had completely broken down, not only admitting to accepting bribes but also providing several key pieces of evidence of financial fraud by Liu Haotian Group.

Two hours later, the conference room of the Criminal Investigation Brigade was filled with smoke.

The projector displayed Li Shang's information.

Deputy Director of Finance at Wuzhou Group, 42 years old, unmarried.

"The action team has already set off to invite Li Shang back for tea."

Huang Xiao handed Luo Fei a cup of strong tea.

"Captain Luo, how did you come to the idea that the money would be in the latrine?"

Luo Fei took a sip of tea, which burned his mouth and made him wince.

"That guy had black stains under his fingernails, and he smelled terrible, but it wasn't just body odor; it was a mixture of feces and pond mud. Plus..."

He pointed to his temple.

"intuition."

Huang Xiao curled his lip.

"It's intuition again. Every time they solve a case, they say it's intuition, when they clearly have amazing observation skills but they're just pretending."

Just as Luo Fei was about to retort, his phone suddenly rang.

His expression changed drastically after he answered the phone.

"What? Li Shang is dead?"

Police tape was put up outside Li Shang's apartment.

Luo Fei bent down and crawled under the yellow line, where the forensic doctor was taking photos as evidence.

"The preliminary assessment is that it was a suicide."

The on-site supervisor reports.

"When they found her, she was hanging from the living room fan, with a kicked-over stool at her feet. The time of death was approximately six hours earlier."

Luo Fei put on gloves and looked around the tidy one-bedroom apartment.

"What a coincidence, we just found out he committed suicide?"

He approached the body.

Li Shang's face was bluish-purple, his tongue was sticking out, and there were clear ligature marks on his neck.

Luo Fei suddenly leaned closer and took a sniff.

"It smells like perfume, and it's a women's fragrance."

Huang Xiao noticed it too.

"Why would a bachelor's house smell like women's perfume?"

Luo Fei began inspecting the room.

The desk drawer had been opened, the sheets were wrinkled, and the laptop was on but the screen saver was running.

"Someone came here and rummaged through things."

Luo Fei pressed the space bar on his computer, and the screen lit up.

"Password required."

He turned to the bedside table, where a wallet and car keys were placed.

"Where's the cell phone?"

The police officers at the scene shook their heads.

"did not find."

Luo Fei crouched down to check under the bed and suddenly spotted a flash of light.

He used tweezers to pick out a small piece of sequin.

"what is this?"

Huang Xiao leaned closer to take a look.

"Like... sequins on clothes? Or nail decorations?"

Luo Fei stood up, his gaze sweeping across the room before finally settling on Huang Xiao's work badge.

He stared at it thoughtfully for a few seconds, then suddenly laughed.

"interesting."

"What did you find?"

Huang Xiao was baffled.

Luo Fei winked mysteriously.

"I did make a discovery that amazed me, but it was unrelated to the case."

He turned and walked out.

"Let's go back to the station first. Our only way to break through now is to start with that assassin."

Luo Fei stood in front of the police station's whiteboard, tapping lightly on Heiwa's photo with his fingers, a meaningful smile playing on his lips.

"That Heiwa kid, he'd risk his life for his wife?" He turned to look at his colleague beside him.

"Have you found out what exactly happened between him and Kong Yuzhu?"

Officer Xiao Wang, who was in charge of the investigation, pushed up his glasses.

"Captain Luo, we've found out. Heiwa and the deceased Li Shang were childhood friends, and Kong Yuzhu was introduced to Heiwa by Li Shang. This woman was a compulsive gambler who squandered all the money Heiwa had earned over the years."

"interesting."

Luo Fei narrowed his eyes.

"They were talking about divorce just a few days ago, and suddenly they're back together?"

"Yes, the day after Li Shang died."

Xiao Wang added.

"We suspect that Li Shang gave Heiwa a large sum of money before he died."

Luo Fei suddenly slammed his hand on the table, startling his colleagues.

"That's right! Heiwa isn't confessing because if he does, the money will be recovered, and what will happen to his wife then?"

The officers in the office exchanged bewildered glances. Huang Xiao frowned.

"Captain Luo, you mean..."

"Start with Kong Yuzhu."

Luo Fei's eyes gleamed with cunning.

“Heiwa can kill for her, and he can shut her up for her. We need to create some ‘problems’ between them.”

Xiao Zhang from the technical department happened to be passing by, and Luo Fei's eyes lit up.

"Zhang Xiaobo! Come here!"

The young technician froze, then slowly moved over.

"Captain Luo, is something the matter?"

Do you know how to use AI face-swapping?

Luo Fei was straightforward.

Zhang Xiaobo pushed up his black-rimmed glasses.

"Yes, I will, but..."

"No buts."

Luo Fei interrupted him.

Do you have any porn on your computer?

The entire office fell silent instantly.

Zhang Xiaobo's face flushed red, and he stammered.

What is porn?

"Pretend! Keep pretending!"

Luo Fei laughed and walked a few steps to Zhang Xiaobo's workstation.

"Come on, let Brother Luo take a look at your 'study materials'."

Zhang Xiaobo was panicked and at a loss.

"Captain Luo! No! I...I really didn't!"

Luo Fei plopped down in Zhang Xiaobo's chair and expertly opened his Xunlei (Thunder) application.

The screen prominently displays various clearly categorized video files.

"Tokyo Hot Series," "Selected European and American Works," and "Amateur Compilation"

Luo Fei read it out slowly and deliberately, and with each word, Zhang Xiaobo's face paled a little more.

The office erupted in laughter.

Several young police officers laughed so hard they slapped the table.

"Zhang Xiaobo! I didn't realize! Three terabytes of study materials!"

Huang Xiao couldn't stand it anymore.

"Alright, alright, everyone has hobbies when they're young. Luo Fei, don't go too far."

Luo Fei closed the window and winked at Zhang Xiaobo.

"Don't delete it, I need it."

He turned to Huang Xiao and said.

"Come on, let me take you to meet that 'virtuous' Ms. Kong."

Two hours later, Luo Fei and Huang Xiao returned to the police station and went straight to the technical section.

"How about it?"

Luo Fei asked Zhang Xiaobo, who was busy in front of the computer.

Zhang Xiaobo didn't even look up.

"As you said, we found a Japanese actress with a similar figure, and the male lead is also someone with a build similar to Lee Sang. But the facial replacement will still take time."

Luo Fei leaned closer to the screen and took a look.

"Blurring the dots creates a candid mobile phone photo effect."

He suddenly remembered something.

"Wait, Kong Yuzhu has a special mark."

He picked up the graphics tablet from Zhang Xiaobo's desk and sketched out an exquisite butterfly tattoo with a few strokes.

"It's on the right side of her lower abdomen, very discreet. Add this detail."

Zhang Xiaobo stared in amazement at the lifelike pattern.

"Captain Luo, you have this skill too?"

"Stop talking nonsense and get it done."

Luo Fei glanced at his watch.

The interrogation room was brightly lit and glaringly white. Heiwa sat on an iron chair, the handcuffs on his wrists reflecting a cold light.

He tilted his head, a disdainful smile on his lips, but his eyes were as sharp as knives.

Luo Fei pushed open the door and entered, followed by Huang Xiao.

He was holding a folder in his hand, with a half-smile on his face.

"Heiwa, we meet again."

Luo Fei pulled out a chair and sat down, then slammed the folder onto the table with a "thud".

"Have you thought it through? How about we talk about the Liu brothers?"

Heiwa chuckled.

"Officer Luo, I've told you so many times, I don't know any Liu brothers. Are you police officers all deaf?"

Huang Xiao frowned, about to lash out, but Luo Fei raised his hand to stop him.

"Don't get excited, Huang Xiao."

Luo Fei slowly opened the folder.

"Heiwa, do you know what I admire most about you? It's your toughness. But..."

He paused.

"Being assertive depends on the situation, don't you think?"

Heiwa snorted dismissively.

"Officer Luo, bring it on. I, Heiwa, have done nothing wrong. At most, I'll be charged with attempted murder and sentenced to a few years. I'll accept that. Don't try to pin anything else on me."

Luo Fei suddenly laughed, the sound particularly jarring in the cramped interrogation room.

"So you think you're all upright and honest! Heiwa, do you really think we don't know what you've been up to all these years?"

He leaned forward and lowered his voice.

"You're nothing more than a dog that Liu Haotian keeps."

Heiwa's expression changed instantly. He straightened up abruptly, the handcuffs rattling loudly.

"Luo Fei! Don't you fucking insult me!"

"Anxious?"

Luo Fei leaned back in his chair, a victor's smile on his face.

"Looks like I hit the nail on the head."

Huang Xiao watched in stunned silence.

He then understood Luo Fei's strategy: first provoke the other party, then gradually break down their psychological defenses.

Heiwa forced himself to calm down.

"Officer Luo, your attempts to provoke me won't work. I've said I don't know you, and that's it. Believe it or not."

Luo Fei calmly pulled a photo out of the folder and pushed it in front of Heiwa.

"You must know this person, right?"

The photo shows Li Shang being escorted into the police station.

Heiwa's pupils contracted slightly, but he quickly regained his composure.

"Yes, I know him, he's my buddy Li Shang. What's up?"

"Your buddy?"

Luo Fei sneered.

"Heiwa, do you know what Li Shangdu confessed?"

For the first time, Heiwa's expression wavered.

"Li Shang will not betray me."

"Oh? So confident?"

Luo Fei tapped his fingers lightly on the table.

"Did you know that he even brought up the South China Sea issue?"

Heiwa's body visibly stiffened.

The South China Sea was a secret shared by him and Li Shang; even his wife didn't know about it.

Luo Fei pressed his advantage.

"David and Yan Shishi, these two names should be familiar to you, right?"

Cold sweat began to bead on Heiwa's forehead.

He stared intently at Luo Fei, trying to find a flaw in the other's eyes.

"Impossible, Li Shang wouldn't."

"Can't do anything?"

Luo Fei suddenly raised his voice.

"Won't betray you? Heiwa, you're too naive! Li Shang, in order to get a reduced sentence, pinned all the murders on you. He himself might just get a suspended sentence and be fine. But you..."

He deliberately dragged out the tone.

"Just wait to get shot."

The air in the interrogation room seemed to freeze. (End of Chapter)
