After driving for more than two hours, we arrived outside the village where Pei Jianye's old home is located.

Since it was still some time before dawn, we rested in the car outside the village to replenish our energy.

After sleeping for two or three hours, it was daylight.

We washed our faces with mineral water and then entered the village to look for Pei Jianye.

When we arrived at Pei Jianye's home, we found two white lanterns hanging at the entrance, and several elderly people with white armbands sitting in the courtyard, knocking on things.

Pei Jianye's family was holding a funeral!

I felt a bad premonition and hurriedly asked where Pei Jianye was.

An old man replied that Pei Jianye had committed suicide and today was the seventh day after his death.

Chen Wei and I exchanged glances, both seeing shock, confusion, and helplessness in each other's eyes.

After painstakingly investigating for more than a week, we finally found a lead and rushed over overnight, only to be met with this result.

Just as we were unsure of what to do next, a man in a suit walked over.

This man claimed to be Pei Jianye's lawyer. After verifying our identities, he took out a letter from his briefcase.

"This is a letter that Mr. Pei entrusted me to deliver to you both during his lifetime."

I accepted the letter, noting that it was sealed and had not been opened.

Chen Wei and I stepped aside, opened the letter, and took out a piece of paper.

The letter's content was not lengthy, only a few hundred words.

Officer Chen, Mr. Yu:

By the time you receive this letter, you must have already been investigating me.

That's right, I am the culprit of the "serial disembowelment case" you have been investigating for more than a year.

I am deeply aware of my sins and have no face to meet you again; I can only tell my story in this manner.

On August 8, 2008, the night of the opening ceremony of the Beijing Olympics, my daughter, Xiaoyu, was born.

At that time, my wife and I both had stable jobs, and I thought this was the start of my happy life.

But this happiness lasted less than six years.

June 12, 2014, I will never forget that day.

That day, my daughter Xiaoyu went missing while playing in the park. She disappeared in an instant when I looked away.

My wife and I searched for a long time, reported it to the police, sought help online, and organized searches on our own.

We tried all possible avenues, but there was still no news.

During that period, many children went missing in Kun City.

I organized a "child-seeking mutual aid association," hoping to get more help through online exposure.

But before I accepted Mr. Yu's interview, I got information from a channel.

My daughter had been kidnapped by a human organ trafficking gang and was disemboweled alive to harvest all her useful organs!

To avenge my daughter, I secretly approached the human organ trafficking gang and finally got their invitation to become the chief surgeon performing the operations.

In the following years, I collected evidence of the gang's crimes.

The more I investigated, the more terrifying I found this gang.

I knew that relying on my own strength alone, I could not bring down this gang.

In 2017, my wife died of chronic illness, caused by accumulated grief.

Before my wife passed away, she was still haunted by our daughter's disappearance.

I never dared to tell her that our daughter was already dead, disemboweled, and left without a complete body.

After my wife's death, I decided to seek revenge.

I left the hospital and opened a small clinic, spending every night studying criminal investigation and counter-investigation techniques.

The purpose was to exact revenge on my enemies and avenge my daughter.

A year later, I personally killed the seven people directly responsible for my daughter's death.

Six medical staff and one human trafficker who kidnapped my daughter.

I disemboweled them just like my daughter had been disemboweled, taking back the organs from them.

After killing those seven people, I began preparing to destroy the human organ trafficking gang.

Finally, I found an opportunity and used the "counter-killing case" to guide you to investigate the human organ trafficking gang.

When you had no clues, I provided you with clues.

Now, this human organ trafficking gang has finally been destroyed.

My great revenge has been achieved, but unfortunately, my hands are already stained with blood.

I no longer have any relatives in this world, and death is my only true destination.

Officer Chen, Mr. Yu, farewell forever.

Pei Jianye's Final Note.
