The people from the technical investigation department brought over the monitoring device, and after adjusting it, they raised their heads and made an 'ok' gesture to Li Zan.

Li Zan pressed the communication switch and signaled the young detective to continue questioning.

Little detective: "Hello? Are you still there? Hello -?"

The mysterious man who claimed to surrender said: "Five minutes and 10 seconds."

Young detective: "What?" He looked up at all the detectives gathered around him, pointed at the communication device and shook his head to express that he didn't know what the time meant.

Li Zan raised his hand and said nothing, but Chen Jie quickly handed over a piece of white paper and a ballpoint pen. She mouthed silently, "Boss, please!" She was undoubtedly a complete bitch.

Li Zan wrote a few words on a piece of white paper, turned it over and showed it to the little detective: Silence time.

The young detective suddenly realized that from the moment he learned that the mysterious man had committed a murder and said he wanted to surrender, to the time everyone in the criminal investigation team learned that Li Zan came out and the technical investigation department moved in the monitoring equipment, the total time it took was 5 minutes and 10 seconds.

In other words, during this period, this mysterious man had been counting the time silently, otherwise it would not be accurate to 'seconds'.

The little detective's mind was running at high speed, and when he was trying to lower the vigilance of this mysterious man, he heard the mysterious man say: "I know you are monitoring me... Don't waste your efforts, I can tell you clearly, you can't find it."

Where am I? You need to know that you are the passive party and I am the active party. Okay, let someone else answer the call and I will tell you the murder I committed."

The little detective held the headset, sweating on his forehead. He had been in control of the conversation between the two until now. He opened his mouth, trying to find one word from the countless topics that would allow him to regain the initiative.

The headset on his fingertips was suddenly taken away. The young detective raised his eyes in surprise. When he saw that it was Li Zan who took the headset, he took the initiative to step aside.

Li Zan said into the headset: "Who do you want to answer the call?"

The man was laughing, his laughter distorted by the voice changer: "Chen Jie. Let her answer."

Chen Jie, who was suddenly called out, pointed at herself and couldn't believe it: "Me?" She wondered how the other party could call her name accurately, took the headset, cleared her throat and said, "I am Chen Jie."

"Chen Jie."

"Well. You took the initiative to call me to answer the call. I can understand that you trust me?"

"You are different from them."

"you know me?"

"Don't you want to know how I kill people?"

"……you say."

There was silence in the criminal investigation office. There was only the faint rustling sound from the monitoring equipment and the strange voice disguised by the voice changer describing the murder process unhurriedly. It felt like listening to some midnight radio murder case.

"The first time I committed suicide was when I was 20 years old. I was under a lot of pressure when I just graduated. The boredom and resentment accumulated in the past turned into a knife that cut my heart over and over again. My heart was cut into pieces, and it cut me again.

My brain... the pain drove me crazy. I screamed and roared in pain. I often saw the doctor and took medicine on time, but it was of no use. I can’t do it anymore. Chen Jie, I can’t do it anymore.”

The accent was weird, as if he was out of control, and the pitch was ups and downs, but was forcibly suppressed by the voice changer, making it appear harsh, as if an earthworm was twisting its body in an attempt to crawl out of the dark, damp soil, but was screaming due to exposure to the sun.

"...I went to kill people, and I found peace. My heart is gradually healing, and my brain no longer hurts."

Sounds like a mental patient. Chen Jie thought to herself and answered the question non-stop: "Who did you kill?"

―――

Silent silence.

Just when Chen Jie thought the other party wouldn't answer, she heard the word "garbage".

The word "garbage" was the fuse, quickly igniting the anger on the other end of the call. The sharp and mechanical voice roared angrily, echoing in the ears of everyone in the criminal investigation office, and the effect was comparable to the three-dimensional surround sound of human beings.

"Those are garbage! Scum!! I killed them, I saved them! Only death can completely wash away their sins!" After the other party roared, he unexpectedly quickly regained his composure: "It was a rainy day, the sky

It seemed like a big hole had been broken, and heavy rain poured down, and the sky was as dark as night. It was very quiet all around, the weather was a bit cold and a bit stuffy, I took off the smelly towel stuffed in the garbage mouth, and he stared at me fiercely,

Swearing loudly and using harsh words, like a gossip in the market, hahaha..."

"Then I cut off his hamstrings and hand tendons, and then cut off his two calves and ten fingers. As soon as he started scolding him, and when he realized that I was serious, he started begging for mercy, offering one million, ten million, five thousand

I bought his life at a price of 10,000. How is his life worth 50,000,000? Alas, he couldn’t even figure out his own position. Seeing that I was indifferent, he cried and fussed, became incontinent with fear, and howled like a slaughtered pig.

, it sounds so unpleasant." The other party sounded disgusted, and then asked excitedly: "Then I will cut off his - guess which part of him I will cut off?"

Chen Jie's scalp went numb just by hearing the description. She hesitated for a while and guessed: "Tongue?"

"wrong!"

Fuck! If it’s not a tongue, what is it? Eyes? The feet and fingers have been chopped off. Which part of the body is missing that can most intuitively create a sense of shock and oppression?!

Li Zan knocked on the table and turned over the white paper. Two words were written on the white paper -

"Castration." Chen Jie read out.

"Correct answer!" the other party said: "Genitalia is the root cause of male crime."

Li Zan wrote a line for Chen Jie to read: Ask him how many people he has killed.

Chen Jie asked, and the other party replied regretfully: "Only one person died in my hands."

Phew - everyone breathed a sigh of relief at the same time. Only killing one person meant that he was not a serial murderer.

Chen Jie asked cautiously: "Where are you now?"

"I want to surrender, not now."

Chen Jie asked: "When was that? What's your name? How old are you? Where are you from? You -" She looked up at her colleagues who were staring closely at her, spread her hands and said: "Hang up."

Everyone was in an uproar: "What kind of surrender is this?", "If not now, then when? Thirty years later? Fifty years later? He is provoking the public security system!", "This person has a performing personality. He said he

Murder, there is no body, no detailed information about the deceased, just a few words is a waste of police power."

…

"What if what he said is true?" Ji Chengling looked around at the policemen present, and finally looked at Li Zan. The latter had no expression, but listened carefully, which invisibly gave Ji Chengling the courage to encourage him to continue his analysis: "This person

Frequently seeing a doctor and taking medicine shows that he has psychological and mental problems. But he should stop seeking medical treatment now because he says it is useless."

Lao Zeng: "What if he had a hallucination and fantasized about killing people when he was sick? On the other hand, if he really killed someone, what was his psychology for actively provoking the police?"

Chen Jie: "Get attention?"

Lao Zeng: "Then he should contact the media. The killing scene he described is abnormal, torturing and humiliating. Compared with the common reasons for killing, its starting point is punishment. This person mentioned that 'death can cleanse you.

"Sin', treating the victim as 'trash', he thinks he is cleaning up dirty things, and may be packaging himself as a savior - based on the premise that he really kills people."

Ji Chengling: "As long as we find the person he killed, we can prove it."

Chen Jie opened her mouth, then closed it, and pressed the inner wall of her right cheek. She was actually very confused as to why the person on the call knew her.

Li Zan asked the technical investigation personnel: "Can it be located?"

Technical investigation personnel: "Locate a public telephone booth in Yanziling, Electronic Industrial Zone, Lianzhi District. There is an abandoned factory there, but there is no surveillance nearby. It is difficult for us to find the caller's information, but we can restore the call processed by his voice changer.

sound."

Recovering the caller's voice can roughly determine his age. Li Zan said: "How long will it take?"

Technical Scout: "Half a day."

Half a day has passed very quickly, and the audio they recorded has some artificial noise and jitter, which is difficult to recover.

After Li Zan had a few discussions with the technical investigation personnel, the technical investigation personnel moved the monitoring equipment back to the technical investigation department and sent the recovered audio later.

Chen Jie came over and asked: "Boss, how should we handle this case? There are no conditions for filing a case, and we are not sure whether the murder is true or false, so we cannot waste police resources on the investigation. But if it is true, we will miss the opportunity to arrest the criminal."

Ji Chengling: "Why don't we check the unsolved murder cases in recent years? Chen Jie, when did you transfer to Dongcheng District? Which district did you work in before?"

"I worked in the anti-pornography team in Lianzhi District for two years." Chen Jie asked hesitantly: "Do you suspect that the caller has had face-to-face contact with me? He lives in Lianzhi District?"

Ji Chengling: "Not necessarily. But he knows you, which means you were very close to each other. Captain Li, we will investigate the unsolved cases in Dongcheng and Lianzhi districts."

Li Zan walked around behind Wang and took a look at his computer. The black screen and white codes were densely packed like thousands of ants stacked together.

At a glance, it was clear that Wang was using his working hours to try to crack the firewall somewhere. Li Zan lightly kicked Wang's chair: "Comrade Wang, please restrain yourself."

Wang was startled. With a trembling hand, he held down the mouse and deleted an important line of code. In turn, it was blocked by the firewall on the opposite side. He glanced at Li Zan resentfully, who had no guilt at all and his face was filled with anger.

Say honestly: "I am doing it for your own good."

Wang moved the green plants on the right corner of the desk to the left to block his annoying colleagues and become an autistic mediocre person.

Li Zan tiptoed, pulled the swivel chair next to him and lay down lazily. He said without raising his eyelids: "Which years do you want to investigate the case? The caller said that he killed someone when he was 20 years old. If he is 40 now,

You are not allowed to investigate unsolved cases from 20 years ago?"

Ji Chengling was a little unconvinced: "Then what do you think we should do?"

Li Zan: "There are two possibilities for this matter. One is that the caller lied, and the other is that he did kill someone, but the murder was not discovered."

Ji Chengling: "Why?"

Li Zan: "Because the deceased's death was too brutal. He had his arms and legs cut off, he was castrated, and there may have been more cruel torture that he did not describe. The unsolved case of this kind of death is enough to shock the society... and I have never heard of this."

An unsolved case."

Chen Jie thought for a while and then said: "I haven't heard of it either. If such a bad case really happened, it would have spread throughout the entire police system. Ji Chengling, did you hear about it when you were studying at the Public Security University?"

"No." Ji Chengling did not forget to ask: "What if it is indeed a long-standing case?"

Li Zan: "No."

Ji Chengling asked: "How are you sure?"
