"Okay, okay," Yang Wenbin waved his hand weakly, "I don't have the strength to quarrel with you now." How much did you write down from the survey just now? ”

"It's all here." Yan Junli took out the small notebook from his breast pocket, but this notebook had been with Yang Wenbin since he first met him. Yan Junli flipped through the contents of the notes.

"It's not very useful, but there's an interesting phenomenon." Yan Junli pressed out the ballpoint pen with his chin and drew some sentences with the tip of the pen, "Anyone who has known Xiao Yang and knows him a little bit well will say that he is a very eccentric, but not bad-hearted person. ”

"Why on earth did he kill those women who had never known him?" Yang Wenbin asked.

“…… I do not know. Yan Junli had no choice but to tell the truth frankly, "I don't know much about serial murderers. To be honest, I can't imagine why a person would go and randomly murder passers-by on the street, there is no motive at all for such a thing......"

"Just like a hunter." "They're different from us, they don't feel like they're human at all. ”

"Oh?" Yan Junli turned his head sideways, revealing a look of "listening attentively".

"I've privately investigated a lot of history's famous unsolved serial murders." Yang Wenbin wrenched his hands and said, "The murder of black dahlia in the United States, Sam's son, and Jack the ripper in Britain...... Then I found out that the murderers of these murders all have something in common. They are extremely conceited, inflated, and regard themselves as gods and others as cattle and pigs. In their eyes, there is only a difference between hunters and prey, and these very few people cannot obtain emotions through normal life, and can only bring a little comfort to their souls by killing. Some even treat killing as a way to show off, and they feel that they are very proud of the crimes they have committed that have left the police like headless flies. ”

“…… Perhaps, sometimes human nature is a terrible thing. Yan Junli muttered, turning to the last page of the notebook. Sandwiched there was a photograph of the prisoner Xiao Yang. The man in the photo is still very young, wearing a prison uniform, his hair is shaved, but his handsome face is cold, and his eyes are glazed in the direction of the camera.

"Do you think such a young man would be the murderer of a serial murder?" Yan Junli flipped the photo to Yang Wenbin.

"It's hard to imagine." Yang Wenbin shrugged his shoulders and judged, "And listen to you, all the victims were killed by a knife cutting their throats?" ”

Yan Junli nodded, "One knife to death, no hesitation." ”

Yang Wenbin frowned, "That means that the result that the murderer wants is the death of the victim." Don't you think that's a little weird? ”

"What's strange?" Yan Junli shrugged his shoulders, "Murderer, murderer, what do you want to do if you don't want to kill?" ”

"But you also said that your profiler analyzed that Xiao Yang's crime was due to his mother-love complex, and he was a person who lacked maternal love since he was a child. The motive for such crimes is often not as simple as 'killing'. Yang Wenbin said affirmatively, "To a large extent, murderers will indulge in the process of sadism, dismemberment, and killing, and this process is what they enjoy." ”

Yan Junli opened his mouth, and just wanted to say something, but was interrupted by the ringtone of his mobile phone.

"Hello?" Yan Junli picked up the phone.

"Team Yan, how is your investigation?" It's Li Hong on the other end.

Yan Junli glanced at Yang Wenbin and shrugged his shoulders, "Huh...... That's it. Nothing important to mention. ”

"Very well, then you don't stay there to investigate what is available." Li Hong still had a slight gasp between words, "You'd better come to the police station." ”

"What's wrong?" Yan Junli immediately asked.

"I think our prison escapees ...... A letter was left for the police. Li Hong held a crumpled piece of paper in his hand and said with a sad face.

——————————————————————————————————

"What's wrong?" Yan Junli strode into the police office, and Li Hong was waving at them.

"That's it, today's evening newspaper." Li Hong unfolded the crumpled piece of scratch paper, pointed to an inconspicuous corner and said, "The criminal was afraid that we wouldn't notice, so he made a special trip to send it over." ”

"I'll see." Yang Wenbin took the paper in Li Hong's hand and browsed the contents on it.

The letter was cut and pieced together from other newspapers or magazines, crooked, and not easy to read, and Yang Wenbin struggled to put all the words together:

- I'm going to have fun with the police, I killed the warden, just as I did five years ago. I didn't want to, but he died a crime he deserved. The demon took control of my body, and the laugher could have the last laugh.

Yang Wenbin finished reading the full text, and several people were all confused.

"What the fuck does this mean?" Yan Junli was puzzled.

"Needless to say? A letter of provocation to the police, of course. Yang Wenbin put the letter back on the table.

"Can you tell me something I don't know?" Yan Junli said helplessly, "I mean, I don't understand what this letter is trying to convey at all. ”

"Me too." Li Hong agreed, "That's why I called you two over." ”

"The content of the letter was originally spliced together with other printed words, so it is normal for it to be difficult to read." Yang Wenbin stroked the uneven place on the letter, "What matters is the tone of this letter. You see, the person who wrote the letter must have been very arrogant, and almost all the sentences in this letter start with the first-person 'I', and the first sentence is 'I'm going to have fun with the police.'" The next few sentences are almost all imperative sentences with an arrogant tone. Then he generously confessed his crime, and there was an element of showing off in it. This is an arrogant and conceited murderer, and in his eyes the police are like a bunch of fools who will never catch him. ”

"And how do you explain the next few sentences?" Yan Junli asked.

"Maybe he's not exactly a mindless villain." Yang Wenbin pointed to the last two sentences and analyzed, "He said, 'I didn't want to (kill him)', and 'The devil took control of my body'." I believe that Xiao Yang still has at least a vestiges of kindness, otherwise he would not have confessed in his letter to the police. ”

"But what's that last sentence?" Li Hong was puzzled, "What is a 'laughing man'?" I couldn't even tell if it was a noun or a verb. ”

Yang Wenbin shook his head, he really didn't understand the meaning of the last sentence. Just when Yan Junli and Li Hong were a little disappointed, Yang Wenbin suddenly said,

"Wait. There are also words here. ”

Yang Wenbin lifted the small newspaper clippings on the paper, and found that there was still blurred handwriting under the stickers. Yang Wenbin immediately carefully tore off all the stickers, and sure enough, the information hidden under the stickers was coherent. But the content is even more creepy.

- I was born in hell, and now I am back in the arms of death.

The handwriting is illegible. It looks like it was written in pencil, and the strokes are trembling, and it doesn't take a good sense of observation to see how nervous the person who wrote the sentence is.

"W-What does this mean?" Yan Junli looked up at Yang Wenbin, "This means that he is going to start killing again?" Or is he already ...... himself?"

"That means, we're going to have to start a full-fledged search soon." Yang Wenbin slapped the letter on the table, "Xiaohong, ask your subordinates to investigate this letter from beginning to end, fingerprints, hair, and any possible traces should not be spared!" Then try to send people to search the whole city, focusing on finding the places Xiao Yang liked to go before he was imprisoned, and don't let go of his school, home, and places where he worked! ”

"Wait," Yan Junli grabbed Yang Wenbin's arm, "You make it clear, what are we looking for?" ”

"Does that need to be said?" Yang Wenbin said decisively, "It's Xiao Yang's corpse." ”

"How are you—" Yan Junli's eyes widened.

"Trust me. Just trust my instincts. Yang Wenbin affirmed.

And it turns out that Yang Wenbin's magical detective-like intuition is really not ordinary.

It didn't take long for the police to find Xiao Yang's body near a stinking sewer.

“…… I regret having eaten so much tonight. This was Yan Junli's first reaction.

"Oh my God." Li Hong pinched his nose the whole time, and his voice was sharp, "I can't tell which is the corpse and which is the dirt from the sewer." ”

"Give, wipe it near the human center, it will be of some use." Yang Wenbin didn't know where to take a box of cool oil and threw it to Li Hong, but he didn't seem to smell it at all, squatted down in front of the foul-smelling corpse, and put on gloves.

The corpse was horrific and no one knew how long it had been soaked in the stinking gutter, but its clothes had become tangled in feces, swill, and other unknown dirt. Yang Wenbin picked up a branch and got the dirty thing down little by little, which was the face of the corpse.

It was indeed the young man Yan Junli had shown him the photo, but his body had been soaked in the water for too long, which looked particularly terrifying. Yang Wenbin swept over the bare skin of the corpse, picked up the corpse's hand and stared at the tip of his index finger for a while, then reached out to pick away the bloodshot eyeballs, and finally opened his mouth to check his tongue.

"He must have been dead for more than a day." Yang Wenbin judged while inspecting, "Judging from the extent to which the corpse was soaked, I'm afraid it has been dead for at least three days." There is no visible trauma, but there is a possibility of poisoning due to dilated pupils, muscle atrophy, and bluish complexion...... What is it? ”

Yang Wenbin frowned, his fingers poking into the corpse's mouth and groping.

“…… That's when I admire you, Dr. Yang. Li Hong, who was still pinching his nose and resolutely refused to let go, said sincerely.

"At your point, you are still the captain of the criminal investigation team." Yan Junli unceremoniously patted the back of Li Hong's head, then turned to Yang Wenbin and asked, "What did you find?" ”

Yang Wenbin struggled a little, but still found what he was looking for. When he pulled his finger out, there was a small bullet between his fingers.

"A bullet?" Yan Junli asked.

"A bullet. That's right. The 7.65mm caliber bullet is supposed to be paired with a small semi-automatic pistol. Yang Wenbin carefully put the bullet into the transparent evidence bag.

"Do you think he's committing suicide?" Yan Junli asked.

"For now, suicide is the most likely." Yang Wenbin raised his head and looked at the building above him, while backing away to get a full view. Directly above this stinky ditch is an office building, and near the office building are some buildings such as restaurants and shopping malls. The possible speculation is that after Xiao Yang escaped from prison and killed someone, he fled here. But the guilt of starting to kill again and the pressure of being pursued by the police overwhelmed him, so he sent such a letter to the police and chose to commit suicide by poisoning in a no-man's corner. Before he died, he had a bullet in his mouth to express his guilt and ask for forgiveness from the victim. ”

Yan Junli nodded, "Reasonable." ”

"yes, it makes sense, except for a few glaring holes." Yang Wenbin narrowed his eyes and threw a "said you were an idiot, but I didn't expect you to be really an idiot" at Yan Junli, "Where did the poison he used to commit suicide come from?" ”

"What?" Yan Junli didn't react for a while.

"Where did the poison he used to kill himself come from?" Yang Wenbin repeated it again, spreading his hands, "Xiao Yang is a fugitive who escaped from prison, he wants to avoid the investigation of the police, and he also has to avoid the eyes and ears of the citizens, and on this basis, he has to find a place to buy this illegal poison?" ”

Yang Wenbin's words completely blocked Yan Junli and he was speechless.

"Also, look at his fingers." Yang Wenbin squatted down in front of the corpse again, picked up the corpse's fingers, and motioned for Yan Junli to come over and take a look. Yan Junli had no choice but to endure the unpleasant smell and squatted down beside Yang Wenbin.

"What's wrong?"

"Look at his index finger." Yang Wenbin erected the fingertips of the corpse, and Yan Junli immediately noticed that the nails of the corpse's index finger were a little off, and the flesh of the fingertips was open, as if they had been worn by something.

"Did he get it when he was alive?" Yan Junli looked at the wound a little worried, and muttered, "It looks like it hurts." ”

"Definitely." Yang Wenbin put down the corpse and said to himself, "Since you are not here, you must be on a higher level......

"What?"

"Let's go, let's go inside." Saying that, Yang Wenbin took a step.

"No, where are you going?" Yan Junli was confused.

"Do you need to talk about it?" Yang Wenbin pointed to the foul-smelling sewer mouth, "The corpse was washed down from there, of course we have to go up there." ”

"Ahh
