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

“Without inside help, how could the Jiang family have managed to cover for the victim? The police may have already obtained the video, but it was destroyed by certain people. The case has already been decided, and no one wants the truth to be exposed.”

Luo Fei remained silent for a long time.

He recalled the oath he took when he first joined the police force, and the criminals he had personally sent to prison. If even the most basic justice could not be guaranteed, what was the point of his police uniform?
"and after?"

he asked softly.

Teacher Qin's gaze turned gloomy.

“I’ve looked up Jiang Minghui’s information. He’s a spoiled brat and a drug addict. I thought God would punish him and make him dig his own grave because of drugs.”

He sneered.

"But fate is so ironic. During a drug crackdown in Jiangcheng, he successfully kicked his addiction because he couldn't buy drugs, took over the family business, married a wealthy heiress, threw a lavish banquet, and lived a life of unparalleled glory. And my Yutong..."

The old man's voice choked with emotion.

"But it was gradually forgotten."

Luo Fei saw a tear slide down Teacher Qin's cheek, winding its way down the lines of her wrinkles.

He had never seen this usually strong teacher shed a tear.

"So you've decided to do it yourself?"

Teacher Qin wiped away her tears, and her eyes regained their resolve.

"I spent two years learning chemistry, especially drug synthesis. Then I started buying materials and making methamphetamine."

Luo Fei gasped.

The drug case he is currently investigating originated from a highly pure form of methamphetamine.

"You know this is a crime?"

"crime?"

Teacher Qin suddenly laughed, a laugh tinged with madness.

"When Jiang Minghui took Yu Tong's life, what punishment did the law give him? Where was justice when he went unpunished?"

Luo Fei was speechless.

He recalled the countless cases he had handled, the criminals who escaped punishment due to insufficient evidence or interference from authorities, and the desperate eyes of the victims' families.

"You funded Wei Guofu to start a pharmaceutical company, also for this purpose."

"Yes."

Teacher Qin nodded.

“I met Wei Guofu when I was volunteering in prison. He was talented in chemistry but couldn’t find a job after his release. I gave him funding and he took care of the technical aspects.”

The old man had a proud expression.

“He is very capable. In less than three years, we made hundreds of millions of yuan.”

Luo Fei felt a chill.

The Luxiao Group, which he is currently investigating, appears to be a legitimate pharmaceutical company, but is secretly suspected of drug trafficking.

Unexpectedly, the mastermind behind it all turned out to be his own high school teacher.

"Those 'Flower Language Hope Primary Schools'"

"It was all built with money earned from drugs."

Teacher Qin said calmly.

“Every school’s name has the character ‘Yu’ in it, the ‘Yu’ in Yu Tong’s name. I used this money to do what Yu Tong should have done.”

Luo Fei recalled a Hope Primary School he had visited just last week. The children's innocent smiles, the brand-new school building, and the advanced teaching equipment—behind all of this lay the profits from drug trafficking.

"Don't you find it ironic? Using money from drug trafficking to fund education."

Teacher Qin shook her head.

"Money itself is neither good nor evil; the key lies in how it is used. I used this money to build forty-three schools and sponsor thousands of impoverished students. And what about the Jiang family? Every penny of theirs is stained with the blood and sweat of ordinary people!"

Luo Fei fell silent.

He couldn't refute the logic, yet he instinctively felt uncomfortable. As a police officer, he had seen too many families destroyed by drugs, too many souls corrupted by drug addiction.

What happened to Jiang Minghui?

"Relapsed into drug addiction?"

A cold smile curled at the corner of Teacher Qin's mouth.

“It’s very simple. After I got control of the drug distribution channels in Jiangcheng, I discovered that he had started using drugs again. Our products are extremely pure, and he quickly became addicted.”

Luo Fei recalled the forensic report about Jiang Minghui's death: his whole body was ulcerated, his organs were failing, and he had suffered unimaginable pain before he died.

At the time, forensic experts suspected that it was caused by a special formula of drugs.

"Did you add something to the drugs?"

Instead of answering directly, Teacher Qin took a thick chemistry handbook from the bookshelf, turned to a certain page, and pointed it out to Luo Fei.

"This compound itself is harmless, but when mixed with methamphetamine, it produces highly toxic metabolites in the body. Initial users may only experience a stronger 'high,' but this effect diminishes with accumulation."

"They will die slowly and painfully."

Luo Fei picked up on his words and felt a chill run down his spine.

"In the past year or so, the number of drug-related deaths in Jiangcheng has increased tenfold, all because of..."

"It's all because of my specially supplied products."

Teacher Qin calmly admitted it.

“I only distributed this spiked product in the areas where Jiang Minghui bought drugs. The others were just necessary sacrifices.”

Luo Fei suddenly stood up, the chair scraping against the floor with a screeching sound.

"Necessary sacrifices? Those were living, breathing people! They had families and friends."

"What about Yutong?"

Teacher Qin suddenly roared, her face contorted in a ferocious expression.

"She's only nineteen! She just applied for a leave of absence to teach in a rural area! What did she do wrong?"

Luo Fei was stunned by this sudden outburst.

He had never seen Teacher Qin so out of control.

The old man's chest heaved violently, and his eyes were bloodshot.

Silence spread between the two.

Teacher Qin calmed down first, then slumped back into her chair.

"I'm sorry, I lost my composure."

He rubbed his temples wearily.

“Over the years, I’ve dreamt of Yutong every night. I dream of her covered in blood, asking me why the murderer is still alive.”

Luo Fei felt as if an invisible hand was gripping his heart.

He sat down again, his voice low.

“Teacher Qin, I understand your pain, but this isn’t the solution. You know I have to.”

"Arrest me?"

Teacher Qin gave a wry smile.

"Of course, that's your job."

He pointed to the desk drawer.

“There are my confession and all the evidence there, including the transfer records of the Jiang family bribing the judicial system, photos of Du Changfeng accepting bribes, as well as my drug-making formula and ledgers.”

Luo Fei stared at him in shock.

"You were prepared all along?"

"From the day I decided to take revenge, I never thought I could get away unscathed."

Teacher Qin said calmly.

“I just wanted to see Jiang Minghui pay the price. Now, that wish has come true.”

Luo Fei walked to his desk and opened a drawer. Inside were several folders neatly arranged, with an envelope on top that read "To be opened by Luo Fei".

"This is."

"For you."

Teacher Qin smiled.

"Inside is all the evidence I've collected over the years, enough to bring the Jiang family and Du Changfeng to justice. As for my crimes, I will take full responsibility."

Luo Fei's hands trembled.

He recalled that when he was in high school, he almost dropped out of school because of his family's poverty. It was Teacher Qin who paid his tuition and often took him home for meals.

Is the always smiling Teacher Qin really the same person as the old man in front of me who makes drugs to seek revenge?
"why me?"

His voice was hoarse.

"Because you are my most outstanding student."

Teacher Qin's eyes were filled with tears. "He's the most upright policeman I've ever met. I knew you would make the right choice."

Luo Fei felt a wave of suffocation. The right choice? Was arresting his mentor the right thing to do?
Is it right to let corrupt officials go unpunished? The world is never black and white.

"Teacher Qin, have you ever thought about this?"

Luo Fei spoke with difficulty.

"If you had approached Captain Meng Haonan instead of Du Changfeng back then..."

Teacher Qin's expression froze. After a moment, he let out a long sigh.

"Fate is so ironic, isn't it? Of all things to do, I had to run into Du Changfeng."

He shook his head.

"But it's pointless to talk about this now."

Luo Fei clenched his fist.

He recalled Captain Meng's upright and incorruptible face, and the countless stories of him refusing bribes. If only Teacher Qin had encountered Captain Meng back then...
"Du Changfeng won't be able to get away with this for long."

Luo Fei gritted his teeth and said.

"I swear."

Luo Fei suddenly became serious.

"The teacher has already taken revenge, so why continue dealing drugs? Don't you know the harm drugs cause to society?"

"Of course I know."

Before he could answer, Teacher Qin continued talking to herself, her voice suddenly becoming ethereal.

"The people I feel most sorry for are the anti-drug police officers like your parents."

"I am well aware that drug manufacturing and trafficking are heinous crimes, and I have long been prepared to accept legal punishment."

Luo Fei's heart clenched. His parents were a wound he had deliberately avoided for many years, but now Teacher Qin had ruthlessly reopened it.

Do you think drugs are worse, or is it people's hearts that are worse?

Teacher Qin suddenly asked, a strange smile curving her lips.

Luo Fei was stunned.

What kind of trap lies behind this seemingly simple question?
Drug addicts are a social scourge.

"Teacher Qin continued without waiting for his reply, her voice gradually becoming more agitated."

"Their behavior stems from their own character flaws, not from the drugs themselves!"

His fingers nervously tapped on the iron railing beside him.

"I used drugs to punish the murderer who killed my granddaughter. Although it was a crime, it also rid society of a scourge!"

Looking at Professor Qin's distorted face, Luo Fei suddenly realized that the person in front of him was no longer the gentle and refined university professor, but a demon consumed by revenge.

"Human nature is inherently evil!"

Luo Fei retorted sharply, his voice booming throughout the factory.

"Drugs are nothing more than a trigger that unleashes the evil within human nature!"

He took a step forward, raindrops dripping from his tactical boots.

"It is precisely because of the country's control and the efforts of the anti-drug police that most people have been kept away from drugs, avoiding repeating the mistakes of a century ago!"

Teacher Qin paused for a moment, then gave a wry smile.

"You're right, Luo Fei. You've always been my smartest student."

He sighed.

"But I used the money I earned from drugs to help many children in mountainous areas and built three Hope Primary Schools."

His gaze suddenly softened.

"I have harmed people, but I have also saved people. I have no regrets about this ending."

Luo Fei was about to retort when Teacher Qin suddenly lowered her voice.

"I've always wanted to tell you the truth about your parents' deaths."

These words struck Luo Fei like a heavy blow to the heart.

His muscles were tense, and his ears were picking up every syllable of Teacher Qin's voice.

"They did not die in an accidental car crash."

"Teacher Qin's voice was almost inaudible."

"Instead, it was a drug trafficking organization called 'Blueberry'."

A gunshot pierced the night sky.

Teacher Qin's head snapped back, and her gold-rimmed glasses flew off, tracing a bright arc in the air.

His body fell backward, crashing heavily onto the iron platform, and blood quickly seeped into the rainwater.

Luo Fei's mind went blank for half a second, then his special forces instincts took over his body.

He rolled sideways and took cover behind a concrete pillar, simultaneously drawing his sidearm. A sniper! On the opposite mountain!
Based on the ballistics, the bullet came from a hillside about 300 meters to the southeast.

Luo Fei activated his secretly developed "Eagle Eye" system and quickly locked onto a rapidly moving figure on the hillside. It was a woman who was putting away her rifle and preparing to leave.

"stop!"

Luo Fei roared, his voice echoing in the rainy night.

Instead of waiting for support, he jumped directly from the third-floor platform, performing a forward roll upon landing to dissipate the impact, and then rushed towards the hillside.

His body has undergone special modifications, and his muscle fiber density is three times that of an average person.

Luo Fei sprinted through the rain, his speed far exceeding that of the world's sprint champions, leaving a silver trail of raindrops behind him.

In less than a minute, he had closed in on the dark figure.

"Stop! Or we'll shoot!"

Luo Fei raised his gun and aimed, simultaneously activating the night vision function of his tactical goggles.

The woman in black glanced back; her face appeared an eerie green in the night-vision goggles, but Luo Fei was still struck dumb.

Han Zixuan! His first love, whom he lost ten years ago!

This realization made Luo Fei hesitate for a second on the trigger.

In that very second, Han Zixuan had already turned around and raised her gun.

Luo Fei instinctively pulled the trigger, and the bullet struck her shoulder precisely.

Han Zixuan let out a muffled groan and tumbled down the hillside.

Luo Fei's heart almost stopped beating.

He rushed to the bottom of the slope and found Han Zixuan lying in a pile of dead leaves, her right leg twisted at an abnormal angle, and black blood seeping from the corner of her mouth. She had taken poison!
"Zixuan!"

Luo Fei knelt beside her, his trembling hand touching her cheek.

That once radiant face is now as pale as paper, with fine lines appearing at the corners of its eyes.

Ten years have passed. They were high school students when they parted ways, but now they meet again as a policeman and an assassin.

Han Zixuan's pupils had begun to dilate, but she recognized Luo Fei, and a weak smile appeared on her lips.

"Xiao Fei."

"Why? Why did you kill Teacher Qin? Why did you take poison?"

Luo Fei's voice was broken and fragmented, and rainwater mixed with tears slid down his face.

Han Zixuan struggled to raise her hand and touch Luo Fei's face.

"I'm protecting you."

Her breathing grew weaker and weaker.

"Teacher Qin knows. It's too dangerous about your parents; it could kill you."

Luo Fei was trembling all over.

"Who sent you? The Blueberry Organization?"

Han Zixuan's eyes showed some surprise, which quickly turned into relief.

"So you already knew."

Her fingers slipped limply.

"The organization sent me to investigate you, but when I heard you mention our past..."

Her voice grew softer and softer, forcing Luo Fei to lean down and press his lips close to hers.

"I just recognized you."

Tears suddenly welled up in Han Zixuan's eyes.

"You still remember? Our little secret has been going on for ten years. You actually still remember?"

Luo Fei felt as if an invisible hand was squeezing his heart.

He remembered their time in high school, hiding under the big banyan tree on the hill behind the school, Han Zixuan whispering in his ear. (End of Chapter)
