"What do you mean?" Song Yi frowned.

"Aren't you the best guy in the Behavior Analysis Department, and if you want to know what that means, why don't you profile me now, and maybe you'll have the answer." Liu Changshan was still smiling slightly.

Song Yi was silent for a moment, then glanced at Lu Yuan beside him, and then looked at Liu Changshan again: " You were born in a middle-class family since you were a child, life has always been very good, your parents love you very much, they will often take you out to play, but you are very withdrawn, since you were a child, you are different from other children around you, they will like to gather together to play, such as chasing and fighting, and you will be alone from a distance, you actually want to fit in with them, but your IQ is much higher than theirs, you think everyone else is stupid, and playing with a group of fools is intolerable; when other people are still memorizing primary school texts, you have been able to fill in the middle school test papers, your teacher in the first year of junior high school told us that you used to write the test papers, and relied on himself to come up with some problems that were only involved in the third year of junior high school behind the test papers, and then several teachers put these questions in the test papers of the third grade of junior high school, and no one in the whole grade did it. ”

Liu Changshan's eyes narrowed slightly at this moment, but he didn't speak.

"Because there are more and more 'fools' around you, you can't find someone who can really communicate with you on an equal footing, so you let yourself become more and more isolated from the crowd, of course, whether it's your parents or teachers, everyone still cares about you, but you feel that the world is less and less up to your expectations, and the people around you still take some of your own. The mentally retarded idea is imposed on you, what you want no one can give you, and what you don't want, others continue to forcibly instill it in you, our behavior analysis department believes that a person's childhood will have a huge impact on his later life, because that is the period of shaping the three views, and because of this, you will think that parents are people who wear masks and forcibly instill their own things into their children in the name of love, whether they want it or not, like it or not. ”

"To be honest, if we hadn't confirmed that your IQ was really high, then your situation would have been put on other peers, and in layman's terms, you would be a secondary 2 teenager. Song Yi continued: "But it is precisely because of this idea that everyone around you is a fool that makes you more and more establish a perspective of God, you feel that you are another species beyond them, or that you are their evolutionary version, so you feel that you have the power to dominate all fools, just like humans can dissect other primates without psychological concerns, and you will not have psychological pressure to take the lives of 'fools', even if they are your parents." ”

"And I'd venture to guess that the reason you're letting us sit here and talk to you face-to-face is probably because you think we're the same evolutionary species as you. Song Yi looked at Liu Changshan and said.

"What do you think?" Liu Changshan smiled slightly.

"In fact, modern biology can prove that the human brain has not changed much in 10,000 years, and our brain capacity is very similar, so I support the eight billion people on the earth, in fact, all people are similar, and there are many possible reasons for the difference, such as some people are malnourished since childhood, such as some people have not been educated and enlightened since childhood. Song Yi said: "But you don't think so, you didn't even finish high school, you killed your parents on your fourteenth birthday, you don't feel the love they give you at all, but you think it's a kind of forced indoctrination, and in your eyes, these indoctrination that doesn't take into account your feelings is because of something wrong with their brains, so you will hollow out their brains in order to give them a so-called 'cleansing'." ”

"In addition to this, we also learned that when you were thirteen years old, you once took a book of the human body encyclopedia at a neighbor's house, and when you dug up your parents' brains a year later, you may have also had this book, and you may have been puzzled by why you are smarter than everyone else, and you think that it is possible that the brains of these 'fools' are different from the color pictures in the encyclopedia. ”

"Since you killed your parents, you've been addicted, and you're not used to couples who force their thoughts on their children, especially those who are about the same age as your parents, your father is 41 years old after you killed him, and your mother is 39 years old, and when you help them clean their brains, you feel very happy, like you have God-like power, and you can't stop it. ”

"The above is the analysis of you by the Behavior Analysis Department, the reasons for your behavior, your psychological state, and of course, some more, I don't have that much time to explain them all. ”

Song Yi's gushing analysis finally ended, and Liu Changshan, who was opposite him, seemed to be enjoying this analysis, and when Song Yi finished speaking, he was stunned: "It's gone." ”

"What else do you want? What you've done in the five years you've been gone, we can't dissect. Song Yi said.

"You haven't figured out why I'm not going to run away this time. Liu Changshan said: "Or did you fail to meet my expectations?"

Liu Changshan's last sentence directly inspired Song Yi, when the former's voice fell, Song Yi's brain was already running rapidly, his eyes quickly swept over every corner of the room, the little girl squatting in the corner with a frightened face, the victim couple lying unconscious on the ground and not yet dead, and the cake full of candles, and finally Liu Changshan, who was dressed very neatly.

"He's reliving his fourteenth birthday. Song Yi is still looking for clues and analysis, and Lu Yuan, who is good at reconstructing the scene, has already found the answer.

Lu Yuan's words also made Song Yi connect all the clues in the room, he found that there were many candles on this birthday cake, a total of about forty, and according to what Song Yi knew, today was the little boy's thirteenth birthday, and the candles should be thirteen, and corresponding to the current number, there is only one conclusion.

That is, today's birthday cake is for Liu Changshan himself, and he has a fortieth birthday, that day is the beginning of his killing, and the people who were at the scene that day have two identities, one is Liu Changshan himself, that is, the owner of the birthday, and the other is the person who arranged the birthday and offered birthday gifts, that is, his parents.

So it is Liu Changshan who celebrates his birthday now, and who plays the person who celebrates his birthday, and what should be his gift?

No, Song Yi felt that he had overlooked the most critical thing, what was it...

"Could it be that...?" Song Yi understood everything in an instant, and it turned out that everything was like this.

When Song Yi figured everything out, Lu Yuan on the side also looked at him, with a glint in his eyes.

"It seems that you have understood, I really did not misunderstand you, we are the same evolutionary species. Liu Changshan nodded with satisfaction, he touched the gun in his hand, this is a police 92-style 9mm pistol, which he once snatched from a criminal policeman, or in his words, to use it.

"Do you think I'm your birthday present?" Song Yi looked at Liu Changshan, although he already knew the truth, he still behaved calmly.

"I'm going to die here today, it's my last birthday, but I'm not talking about being alone now. After Liu Changshan finished speaking, he directly raised the gun in his hand and aimed at Song Yi's head: "Actually, I said that I have never fired a real gun, do you believe it?"

"Then you have to be careful of the recoil of this gun. Song Yi kindly reminded, and he glanced at Lu Yuan on the side again: "Do you really want to do this?"

When Lu Yuan heard this, he rubbed his palm, and he patted Song Yi on the shoulder: "Actually, I am the best candidate for the position of the leader of the behavior analysis team, you are very good, but you don't understand politics, you may not be able to let this department benefit in the struggle." ”

"You want to be the leader, why didn't you say it at first? I'll give it to you. Song Yi said to Lu Yuan: "I just didn't expect that you would do this for this matter, I've always wondered, why Liu Changshan was discovered by us so easily, I didn't expect that there would be people in the task force who would cooperate with this kind of beast, in fact, you are the one who celebrated Liu Changshan's birthday, right?"

"I'm sorry, but this time you were a gift. Lu Yuan said indifferently: "Don't worry, wait a minute out of this room, I will tell everyone that you were injured by Liu Changshan and died heroically, and I will also become the hero who killed Liu Changshan, by the way, I will correct you, you really don't understand politics, do you think that the position of the team leader is something you let me sit on? As long as you are still in the day, you are the best, I will always be behind you, and a person behind you, how can a person who is behind you be convinced by others and become the head of the behavior analysis department?"

"However, before you die, I have good news for you, and that is that the bombs here don't actually explode, and hearing this news may help you rest in peace. ”

"If Wang Hanyuan knew about this, he would kill you. Song Yi said to Lu Yuan.

"So as long as you don't know, how simple is it?" Lu Yuan smiled faintly.

When Song Yi heard this, he knew that he probably had no way to escape this situation, and it would be Liu Changshan who would shoot next, so the person who killed him was not Lu Yuan, he would not have any legal responsibility, and there were no other witnesses to everything here.

Wait a minute... Other witnesses?Song Yi glanced slightly to a corner of the room, and the frightened little girl actually witnessed everything here.

However, just when Song Yi's pupils were slightly slanted, Liu Changshan already knew his intentions, and saw that he directly turned the muzzle of the gun and aimed at the little girl, and with the sound of a gunshot, Song Yi's whole person froze in place.

The sound of gunfire echoed through the room, and even with the soundproof walls, all the SWAT officers waiting outside could be heard, including everyone standing in the snow outside the villa.

"It's not good! Something happened, everyone will take down the room directly for me!" Wang Hanyuan, who had sharp intuition, gave an order directly, and the armed police personnel who were waiting outside the room also kicked the door open.

At that moment, everyone saw that Liu Changshan's face was relaxed, he smiled with satisfaction, and aimed the muzzle of the gun in his hand at Song Yi, the shot he had just shot at the little girl had already made him feel that he had a talent in controlling the gun.

Is this the end of everything for me? Song Yi thought in his heart that he still had his parents and an older sister at home, and they were still waiting for him to complete this mission and go home for the New Year.

Outside, the snow was blowing, and the wind seemed to be getting stronger, whining in the empty city.

Boom!

The gunshot rang out, and Song Yi felt like a clock that had stopped moving, and he entered eternity.

......
