After the two of them finished the barbecue, Xu Lang paid the bill, and Alan did not say that he would go to Xu Lang's house, nor did he ask Xu Lang to send her back to the bar, but took a taxi and left alone.

After Xu Lang and Alan separated, they returned to their home, first entered the bathroom, took a cold bath comfortably, and after washing, Xu Lang felt a lot more relaxed, and then he entered the bedroom.

Before going to bed, Xu Lang took out the medicine that Shu Yue had left for him from the drawer of the bedside table, poured a glass of water, and after taking the medicine, he went to bed, and it didn't take long for Xu Lang to fall into a deep sleep.

One night without a dream, the next day.

When Xu Lang woke up, it was already seven o'clock in the morning, after opening his eyes, Xu Lang sat up from the bed, leaned on the bed and lit a cigarette, and then, after smoking, he got up to wash, and after washing, Xu Lang returned to the bedroom, changed into a new set of clothes, and then picked up his mobile phone and went out.

On the way to the Public Security Bureau, Xu Lang bought breakfast, and ate it while walking, and when he came to the Public Security Bureau after breakfast, he found that everyone was sitting on the chair tiredly, and everyone's face was not very good, while Wu Yong was sitting on the chair and smoking vigorously, and the ashtray in front of him was immediately filled with dense cigarette butts.

After Wu Yong saw Xu Lang coming, he just raised his head and glanced at Xu Lang, then continued to smoke, and did not speak, in fact, there was no need to ask, Xu Lang saw Wu Yong's expression, and knew that the surprise interrogation of Xue Sheng would definitely be inconclusive, if Xue Sheng confessed, then Wu Yong would not have a black face.

On a chair not far from Wu Yong, Ning Yanran was sleeping on the table, I don't know if Wu Yong had been smoking until Ning Yanran choked, or if he was lying on the table to rest uncomfortable, Ning Yanran didn't sleep well, would she shake her body, Xu Lang was also very speechless, but it seemed that Ning Yanran should have been tired last night, after all, there were many people involved in the arrest last night, and it was also necessary to appease the people at the scene, the workload must be very large.

Xu Lang sat directly opposite Wu Yong, took the information that Wu Yong put on the table and looked at it, and found a lot of new things.

First of all, after a careful on-site investigation was conducted in the 301 rented by Xue Sheng, it was found that no other people's fingerprints were found in the room except for Xue Sheng's fingerprints, which shows that Xue Sheng has always lived in 301, and no one else has come in.

Secondly, in room 301, in addition to finding a few glass jars containing formalin with a soaked tongue, a large number of photos of the deceased and three people who were protected by the police were also found, and two notebooks were also found, one of which Xu Lang had seen before when he entered the room, basically the investigation results of several deceased people, and the first notebook was a diary, in which many things about Xu Lang were recorded, in addition to Xu Lang's photos, There are still many reports about Xu Lang, and there are several pages of them that Xue Sheng used a red pen to record the news of Xu Lang's resignation from the police station for more than three months, this paragraph, he drew a lot of key points, Xu Lang saw this, he was very surprised, he was very curious about how much Xue Sheng's notebook recorded more than himself, but the notebook was not here, Xu Lang did not see it for the time being.

Finally, when a thorough search of room 301 was conducted, a lot of women's clothes were found in Xue Sheng's bedroom, and these clothes were all black without exception, in addition to these, a small set of tattoo equipment was also found in one of the rooms, and a lot of tattoo photos were placed in the room, among which the most tattoo pattern was a pair of butterfly-shaped tattoos, as for why Xue Sheng had a soft spot for this tattoo, it is not clear for the time being.

When Xu Lang read the information, Wu Yong had already smoked two more cigarettes, and after Xu Lang finished reading the information and put the information down, Wu Yong said: "It's been a night of interrogation, and that guy hasn't said a word until now, if it weren't for the fact that he said he was going to go to the toilet during the period, I thought he was a dumb person." ”

Seeing Wu Yong with an indignant face, Xu Lang smiled and said: "The murderer who can kill so many people in a row, after being arrested, is still so calm, naturally it is not a simple character." ”

Wu Yong glanced at Xu Lang and asked, "Do you have any good ideas?" ”

Xu Lang shook his head and didn't answer Wu Yong's question, but asked, "Is the result of the examination of the tongue soaked in formalin out?" ”

Wu Yong saw Xu Lang shaking his head, thinking that he didn't have any good way, so he said, "Not yet, it should be soon." ”

After Xu Lang listened, he stood up and said, "Then I'll go to the forensic office to have a look." ”

After speaking, Xu Lang went to the forensic office, and when Xu Lang came to the forensic office, he found that Ye Xuefei was sitting in front of the computer and looking at things, Xu Lang walked over and asked, "Are the test results of those tongues soaked in formalin out?" ”

Hearing Xu Lang's voice, Ye Xuefei raised her head and glanced at Xu Lang, then stretched out her finger and pointed at the desk, and then continued to look at the computer.

Xu Lang looked in the direction of Ye Xuefei's finger, and then saw a stack of autopsy reports on the desk, Xu Lang picked it up and took a look, and found that the eight tongues soaked in formalin were indeed human tongues, six of which were the tongues of the six deceased who were cut off and lost, and one of the remaining two tongues was the tongue of the deceased Chen Xiao, as for the last tongue, I don't know whose it was for the time being, but according to the autopsy report, the owner of this tongue is a middle-aged man, And the tongue has been soaked in formalin for more than half a year.

With this result, it is basically certain that the murderer is Xue Sheng, but there is a problem that has not been solved, that is, the ethanol found in the body of the deceased has not been found in the room rented by Xue Sheng, and the tool he used to cut off the deceased's tongue has not been found.

Xu Lang now suspects that Xue Sheng may not only have this one residence in S City, but also a secret residence, but it has not been found by the police for the time being.

What Xu Lang should do most now is to think about how to make Xue Sheng open his mouth and take the initiative to explain the facts of the crime, and if he wants Xue Sheng to speak, the first thing to do is to figure out his criminal psychology, how he embarked on the road of crime after being released from prison, only by figuring out these can he find a breakthrough and break through Xue Sheng's psychological defense.

First of all, the reason why Xue Sheng embarked on the road of crime should be related to the fact that he entered prison to serve his sentence and was bullied by the cell boss, according to the investigation of Xue Sheng before he was imprisoned, although Xue Sheng lived in a single-parent family since he was a child, and his father Xue Yiming liked to drink heavily, but the father and son lived a good life, and Xue Sheng was very sensible, whether it was elementary school or junior high school, or later high school and college, his academic performance was very superior, and he got a full scholarship every year, which is an unthinkable thing for many people. But all this changed because of Chen Xiao.

Because Chen Xiao spread rumors everywhere, causing Xue Sheng to be discriminated against at school, many people avoided him, and his girlfriend also chose to leave him at this time, which made Xue Sheng, who was eager to be recognized and respected by others, have great psychological pressure, because he did not go through timely guidance and catharsis, so Xue Sheng chose an extreme way, which was also the simplest and most rude way, that is, he injured Chen Xiao, and he also paid a huge price for it, not to mention losing money, and spent two years in prison.

The reason why Xue Sheng worked so hard was that when Xu Lang was handling Xue Sheng's injury case, he had an understanding that Xue Sheng's father Xue Yiming liked to drink heavily, he was an alcoholic and a drunkard, and the wine was not good, Xue Sheng's mother Chen Hua left Xue Sheng because she couldn't stand Xue Sheng's beating and abuse.

Xue Sheng grew up in the beating of his father Xue Yiming since he was a child, if it weren't for Xue Sheng when he was five years old, because he was sick and went to the hospital and needed a blood transfusion, maybe Xue Yiming always thought that Xue Sheng was not his biological son.

It was also at that time, after returning from the hospital, Xue Yiming never mentioned in front of Xue Sheng that he was a wild seed, but Xue Yiming still did not get rid of his alcoholism, and every time he drank too much, he would still commit domestic violence against Xue Sheng, so Xue Sheng rarely felt his father's love when he lacked maternal love since he was a child, so he was very sensitive, insecure, and paranoid.

When he was in school, he found that as long as he studied well, he could gain the love and respect of teachers and classmates, which gave Xue Sheng a great sense of achievement, so Xue Sheng's academic performance has always been among the best, and Chen Xiao is the one who destroyed everything for him, Xue Sheng naturally hated Chen Xiao very much, so he would go violent, but at that time Xue Sheng was still relatively restrained, he did not kill Chen Xiao, but just injured Chen Xiao, the knife Chen Xiao was injured and hospitalized, Xue Sheng knew that after committing a crime, he went to the Public Security Bureau to surrender, That's why he was sentenced to two years.

And at this time, Xue Sheng was still a relatively normal person, so why did he serve two years in prison, and after he was released from prison, instead of reforming himself and becoming a new person, he carried out a series of operations after being released from prison? This is something Xu Lang can't figure out.

When thinking back on the whole case, Xu Lang found that everything Xue Sheng did from before he was released from prison to after he was released from prison seemed to be planned.

First of all, the cell head of Xue Sheng's cell died unexpectedly shortly before he was released from prison, although the prison investigation results show that the cell head died of a heart attack, but now it seems that the cell boss's death should have some relationship with Xue Sheng, as for whether Xue Sheng killed him personally or indirectly, further investigation is needed.

Secondly, not long after Xue Sheng was released from prison, he did not immediately look for a job, or continue to go to college, but went to Chen Hua, and how he knew that Chen Hua was in TW City, this is not clear for the time being, but Xue Sheng looked for Chen Hua for a purpose, and Chen Hua also told Zhao Hua before the purpose, that is, Xue Sheng took the 150,000 yuan from her, and this money, when Xue Sheng took it, said that it was used to learn tattoos and buy tattoo equipment, but according to Zhao Hua's investigation in TW City, After Xue Sheng got 150,000 yuan from Chen Hua, he did not open any tattoo parlor, but went to have sex reassignment surgery, but the operation was completely completed, Xue Sheng did not completely become a woman, but became a yin and yang person, someone has the appearance of a woman, but the reproductive organs are male, that is, what people often call a ladyboy, as for why Xue Sheng did not continue to complete the operation, it is unknown for the time being.

Then there is Chen Xiao's death, why did Chen Xiao leave S City and go to TW City, and appeared in Xue Sheng's rented room in TW City, what is the secret here, it has not been found for the time being, but it is certain that the reason why Chen Xiao died in TW City must be related to Xue Sheng, as for whether Xue Sheng killed it himself, there is no direct evidence to prove this for the time being.

After that, Xue Sheng used Xue Linhe's identity to return to S City, and after planning for three months, he began to kill people like crazy, why Xue Sheng did this, and what he did it for, it is not clear for the time being.

What makes Xu Lang even more puzzled is why Xue Sheng left a challenge letter for himself after killing Qi Lan, if he didn't leave that challenge book on the Internet café computer, maybe Xu Lang wouldn't think of him, and he wouldn't doubt him, is it really just a challenge to Xu Lang's IQ? It shouldn't be, maybe Xue Sheng already had the idea of giving up killing at this time, the reason why he left the challenge letter was to let Xu Lang find himself and stop him from continuing to kill, as for whether the truth is like this, we still need to wait until all the investigations are over to know the answer.

And all of Xue Sheng's behaviors show that Xue Sheng is planning to kill, and killing Chen Xiao should be his original purpose, only why he returned to S City to kill the six dead may be related to the blow he received before, but what is the truth, we still need to wait until Xue Sheng speaks before he can really understand Xue Sheng's psychological activities.

Now as long as you figure out the above problems, then you can solve the case, but how to make Xue Sheng speak? Xu Lang didn't think of it for the time being.

"Xu Lang, you are here, hurry up, Xue Sheng wants to see you."

Just as Xu Lang was thinking about the autopsy report, Ning Yanran didn't know when she came to the forensic office.

Interrupted by Ning Yanran's thoughts, Xu Lang came back to his senses, looked at Ning Yanran and asked suspiciously, "Xue Sheng wants to see me?" ”

Ning Yanran nodded, she was also a little puzzled, why did Xue Sheng see Xu Lang, just now a colleague bought breakfast from outside, she was woken up from her sleep, and when she was eating breakfast, she also took a breakfast and gave it to Xue Sheng by the way, but she didn't expect Xue Sheng, who didn't speak all night, to take the initiative to speak, and named her to see Xu Lang, Ning Yanran immediately came to the forensic office to find Xu Lang after hearing Xue Sheng's request.

Seeing Ning Yanran nodding, Xu Lang didn't think too much, so he stood up, took the autopsy report and followed Ning Yanran to the No. 1 interrogation room.

Because Xue Sheng asked to see Xu Lang, Xu Lang walked into the interrogation room, and Ning Yanran also followed, holding paper and pen in her hand, ready to take notes.

After the two of them sat down, Xu Lang looked at Xue Sheng, who was sitting opposite, and found that although Xue Sheng hadn't slept all night, he seemed to be in good spirits, which was different from the panic and fear that ordinary prisoners showed after being arrested.

Xue Sheng was eating breakfast before Xu Lang came in, and when Xu Lang came in, Xue Sheng put down his chopsticks, took the initiative to push the lunch box to the edge of the partition in front of the interrogation chair, and then raised his head to look at Xu Lang.

Xu Lang also looked at Xue Sheng, and the two looked at each other for a while, and Xu Lang took the lead in asking, "Do you want to see me clearly?" ”

Xue Sheng looked at Xu Lang and grinned, revealing his white teeth.

Seeing Xue Sheng like this, Xu Lang had to admit that Xue Sheng did look like a woman after plastic surgery, it can't be said to be, it was completely true, whether he was eating, or the expression on his face was very feminine, including the eyes that looked at Xu Lang now, they were all very womanly, which made Xu Lang have an inexplicable illusion, and for a moment, Xu Lang felt that Xue Sheng was actually a woman.

Xue Sheng saw that Xu Lang was stunned when he looked at him, so he raised his hand and brushed the short hair in his ear, and then said: "Officer Xu, oh, no, I should call you Advisor Xu now, I'm very happy, we meet again." ”

Xu Lang looked at Xue Sheng, narrowed his eyes, and then said indifferently: "I'm not happy to see you at all, on the contrary, I feel very sad, it seems that the two years of prison life have not changed you." ”

"NO, NO, NO, Advisor Xu, two years in prison have changed me a lot and taught me a lot, such as killing people." Xue Sheng looked at Xu Lang and smiled.

Xue Sheng and Xu Lang's expressions when they spoke were not like a prisoner facing a policeman, but more like old friends meeting each other, greeting each other, and making family routines.

After hearing Xue Sheng's words, Xu Lang's face did not change much, while Ning Yanran, who was sitting on the side, frowned, anger had already appeared on her face, if she wasn't worried about affecting the next interrogation, maybe Ning Yanran would have exploded in the small universe now, she had never seen a prisoner say murder so lightly, so easily, it seemed that killing people for him was just doing a very ordinary thing, just like studying, like eating, drinking, and Lazar, This is something that Ning Yanran didn't expect.

Xu Lang and Xue Sheng ignored Ning Yanran, and Xu Lang asked directly: "So, do you admit that you did all the six public toilet sinking cases in S City?" ”

Xue Sheng surprisingly did not deny it, but nodded naturally and said: "You are right, I did all six murders, and the body of Chen Xiao that you have found now in TW City, he also killed him." ”

Hearing this, Xu Lang squinted his eyes, he looked at Xue Sheng's eyes, Xue Sheng also looked at Xu Lang, Xu Lang looked at it for a while, and then said, "Then you can tell me more about it." ”

"Advisor Xu, this is a very long story, you have to be a little patient, but don't be like the female police officer next to you, get angry easily." Xue Sheng said with a smile.

When Ning Yanran heard this, she was immediately furious, if it weren't for Xu Lang stretching out a hand and pulling Ning Yanran under the table, Ning Yanran would have slapped the table.

Xu Lang looked at Xue Sheng and nodded, there was no change in expression on his face, he just made a gesture of please.

No one is born a criminal, and no one is born with the desire to commit a crime, and there are many factors that cause and motivate all criminals to eventually embark on the path of crime.

Xue Sheng's family structure has passed before, so I won't repeat it here, the things that changed Xue Sheng's life were actually not Chen Xiao spreading rumors about him on campus, but an incident that happened when he was just in high school.

Xue Sheng's father, Xue Yiming, since he learned that Xue Sheng was indeed his biological son, in addition to feeling deeply guilty about Xue Sheng in his heart, he also missed Chen Hua, and he has not remarried for so many years, which is one of the reasons.

After Xue Sheng went to school, no matter what he wanted or what he lacked, although Xue Yiming still scolded Xue Sheng, he would still meet all Xue Sheng's requirements, of course, Xue Sheng also knew, at the beginning, Xue Sheng was still young, and he would always ask Xue Yiming, why did everyone else have a mother, why didn't he have one? Xue Yiming was always speechless, he didn't know what to say, Xue Yiming lived on alcohol for the first half of his life, although he had a short marriage, but it didn't last long, he resumed his single life, naturally he didn't know how to educate his children, and before Xue Sheng was five years old, he had always beaten and scolded Xue Sheng, Xue Sheng was afraid of him since he was a child, and he didn't want to be close to him, which Xue Yiming also knew.

Once when Xue Sheng asked this question again, it happened that Xue Yiming had drunk, and his problem of drinking too much and getting drunk went crazy again, yelling at Xue Sheng, saying, "Your mother doesn't want us anymore, you should treat yourself as if you don't have a mother." After speaking, he gave Xue Sheng a slap, and then fell asleep, and since then, Xue Sheng has never asked Xue Yiming about his mother's affairs.

In this way, after Xue Sheng finished junior high school, because of the normal performance of the exam, he was successfully admitted to a key high school in S City, Xue Sheng was very happy at that time, and Xue Yiming was also very happy after knowing it, but when Xue Sheng was in the first year of high school, Xue Sheng found that his father seemed to love drinking more than before, almost every day he was drunk, and he was also confused when he went to work, and there were always problems at work. talked to Xue Yiming a few times, and told Xue Yiming that if he didn't change his drinking habits, he would let him get out of the machinery factory, and Xue Yiming had a change.

Later, Xue Sheng knew why his father Xue Yiming became like this, it turned out that at that time, Xue Yiming knew the news of his mother Chen Hua, knew that Chen Hua was in S City, and was married and had children, and Xue Yiming didn't know how to tell Xue Sheng, so he could only drink alcohol, and Xue Sheng only knew about it after he was in his third year of high school.

Xue Yiming once asked Xue Sheng if he went to find Chen Hua and Chen Hua was willing to come back, would Xue Sheng recognize Chen Hua? Xue Sheng had grown up at that time, and he had his own ideas, he shook his head very resolutely, saying that he would not recognize Chen Hua, so Xue Yiming gave up the idea of going to Chen Hua.

Later, during the college entrance examination, Xue Sheng applied for S University, with his excellent results, he was naturally admitted to S University very easily, in the three and a half years of college, Xue Sheng not only studied well, got a full scholarship, but also used the vacation time to do part-time work outside, Xue Sheng has done a lot of part-time jobs, what a tutor, hotel waiter, KTV selling wine, etc., he has done these part-time jobs, in his junior year, during the summer vacation, his father Xue Yiming was hospitalized because of long-term drinking caused stomach perforation, and needed money, Xue Sheng went to an entertainment venue to be a young master, although he didn't do it for a long time, only more than a month, but it happened to be inadvertently seen by Chen Xiao, and then the news about Xue Sheng being a young master in an entertainment venue spread after the start of school, and it spread in S University, many classmates who were closer to Xue Sheng before all stayed away from him, and seeing him was like seeing a plague god, and his girlfriend Susie ran to the entertainment venue to be a young master when she knew that he was actually dating herself, although she didn't do anything illegal, But Susie still couldn't accept it, and the two broke up.

And after Susie and Xue Sheng broke up, about Xue Sheng being a young master, and his father Xue Yiming beat his mother because of alcoholism, which caused Chen Hua to be unable to stand the domestic violence, and the matter of abandoning Xue Sheng gradually spread on the campus of S University, which made Xue Sheng, who had always avoided the truth that Chen Hua abandoned himself and his father, unable to accept it, especially when he saw those classmates who admired him in the past and greeted him with a smile, but now he can't avoid it, which makes Xue Sheng feel very sad, and their counselor naturally knows about it. I also talked to Xue Sheng, which meant the cancellation of Xue Sheng's full scholarship, which made Xue Sheng suffer a huge blow again after being hit by his classmate Bai Yan and his girlfriend Susie leaving.

And he felt that all these news and rumors were spread by Chen Xiao, and this is indeed the case, because Chen Xiao is not only a classmate with Xue Sheng, but also a neighbor who goes up and down the stairs, Chen Xiao's parents and Xue Sheng's father Xue Yiming both work in the machinery factory, and although Xue Yiming loves alcohol, he has a good working ability and has helped the machinery factory solve a lot of problems, so Xue Yiming is the leader of Chen Xiao's parents in the machinery factory, and in school, from childhood to adulthood, Xue Sheng has studied very hard, but Chen Xiao is more playful, The surrounding neighbors will naturally compare the two of them, especially after Chen Xiao goes home every time he goes home for the exam, Chen Xiao's parents will compare Xue Sheng and Chen Xiao, at the beginning, Chen Xiao also felt that Xue Sheng was indeed his own learning model, but after a long time, Chen Xiao also had rebellious emotions, just like finding Xue Sheng's shortcomings, to take revenge on Xue Sheng, so that this good boy in the eyes of adults became a bad child, and the final result was naturally that Chen Xiao succeeded, and Xue Sheng was known because he was doing the young master's thing in an entertainment venue. Everyone will point their fingers when they see Xue Sheng.

Xue Sheng after a painful ideological struggle, finally found Chen Xiao's theory, the last two people talked very unpleasantly, the two people broke up unhappily, not only did the two not talk, Chen Xiao also threatened to completely stink Xue Sheng, so that he could not get a graduation certificate, admitted to graduate school, afterwards, the more Xue Sheng thought about it, the more angry he became, after a strong ideological struggle, I don't know if Chen Xiao's words really made Xue Sheng feel threatened, or Xue Sheng's negative emotions that had been accumulated for many years were finally released, Xue Sheng waved his fist at Chen Xiao.

After Xue Sheng injured Chen Xiao, he went to the police station to turn himself in, because Chen Xiao was seriously injured, and Xue Sheng was a well-known student of the school, coupled with the media at the time, the school gave Xue Sheng the punishment of expulsion, Xue Sheng was also sentenced to two years for intentionally hurting people, in addition to being imprisoned, he also paid a large amount of compensation to Chen Xiao's family, which made Xue Sheng very unwilling.

The reason why Xue Sheng had the idea of killing people was because of prison life.

I also talked about Xue Sheng's appearance before, Xue Sheng is very gentle, very delicate, looks like a girl, he has not enjoyed maternal love since he was a child, and his father Xue Yiming does not know how to communicate with him except for meeting his material requirements, and Xue Sheng is unwilling to tell Xue Yiming about his own affairs, which also leads to Xue Sheng forming a more introverted personality.

When Xue Sheng was sentenced to two years in prison and entered prison to serve his sentence, on the first night he entered the No. 1 room, he did not sleep in bed but paused next to the toilet in the No. 1 room, and the next day he was humiliated by several other prisoners in the cell with the cell boss, because Xue Sheng was very good-looking, so he naturally received special care from the cell boss.

It was at that time that Xue Sheng's psychology gradually became negative, he had been studying hard at school, making progress every day, and working hard to make progress, just to win the respect of others, but now he not only had no studies, but also was treated inhumanely, so he gradually developed a revenge mentality.

In addition to what Xu Lang learned in Fengyun Prison before, Xue Sheng likes to read English books, he also likes to chat with many murderers when he is out of the wind, and learn from them how they kill people, just like this, Xue Sheng is serving his sentence in prison, and he begins to plan his revenge plan after he is released from prison.

First of all, he wanted to kill the cell boss who had bullied him before he was released from prison, and he not only thought so, but also did it, because everyone lived in the same cell, and he knew a lot about the cell boss.

The cell head is a gangster in society, a frequent visitor to the prison, this time he came in because of a fight, cut a person and crippled, was sentenced to ten years, and has now served more than four years in prison, in addition to these basic circumstances, he accidentally learned in a physical examination that the cell head actually has heart disease, and when Xue Sheng was reading in prison, he knew that people with heart disease could not do anything to be greatly stimulated, otherwise it would be easy to cause heart disease because of emotional excitement.

After Xue Sheng knew the news, he made a preparation plan, half a month before he was about to be released from prison, one night, he suddenly found the cell boss and told the cell boss that he was going out soon, and after he got out, he would find the cell boss's daughter-in-law and his children, and kill them when he went out. His face was covered with blood, but despite this, Xue Sheng still looked at the cell head with a cruel smile, and later after the prison guards found out about the situation here, they immediately rushed over and came out, and after pulling the cell head away, they took Xue Sheng to the infirmary to bandage it.

Xue Sheng returned to the cell after the bandage, Xue Sheng has been sleeping next to the cell head in the cell, this night, Xue Sheng still slept next to the cell head, after Xue Sheng came back from the infirmary, he lay on the bed next to the cell head, looking at the cell head with a cruel smile, talking to himself from time to time, talking about how to kill the cell head's family, and after the cell head heard it, his emotions were naturally very excited, and the prison guard was outside, he didn't dare to do anything to Xue Sheng, he could only stare at Xue Sheng fiercely.

In the end, Xue Sheng told the cell boss, "I heard that your woman is already in junior high school, and now she is fifteen years old, and she has begun to develop, and when I get out, I will take good care of your daughter, just like you took care of me after I came in." ”

Just because of Xue Sheng's words, the blood of the cell head suddenly filled his head, and he just wanted to get up from the bed to teach Xue Sheng a lesson, but he didn't expect that at this time, the cell head had a heart attack, and the other prisoners were asleep, so naturally he didn't notice this, Xue Sheng saw that the cell head was sick, instead of calling the prison guard, he covered the cell leader's mouth with his hand and didn't let him shout, and not long after, the cell head died of a heart attack.

When the other prisoners got up the next day, after finding that the cell head was dead, they hurriedly called the prison guards, and when the prison guards came in to check, the cell head had already been dead for a long time, whether it was the prison guards or the other prisoners in the cell, they were all suspected of Xue Sheng, but after conducting an autopsy on the cell leader's body, it was found that the cell head died of a heart attack, and there was no evidence that Xue Sheng killed the cell leader, so after Xue Sheng's sentence expired, he was released from prison.

This is Xue Sheng's first murder, although he did not directly kill the cell head, but the cell boss's death has a lot to do with him, Xue Sheng After killing people, he suddenly felt that killing people was so simple, so he was even more determined to get out of prison and kill people in revenge.

When Xu Lang heard this, he figured out why Xue Sheng did seven murders in a row after he was released from prison, at least seven murders have been found so far, if you add the dead cell bosses in prison, there are a total of eight, as for whether there are other murders, you still need to wait for Xue Sheng to explain slowly.

There was no maternal love since he was a child, which made Xue Sheng insecure since he was a child, because Xue Yiming would only use violence to educate his son, so Xue Sheng did not enjoy the fatherly love that his peers should enjoy, which also led to Xue Sheng's very sensitiveness, making him eager to gain the respect and recognition of others, which when he was in school, he worked hard to learn and progress, and he has always been a good student in the eyes of the teacher, and a scholar in the eyes of his classmates, which is one of the very important performances.

And after he learned that his father Xue Yiming had intensified his alcoholism because he knew the whereabouts of his mother Chen Hua, he had a lot of negative emotions in his heart, in addition to resenting his mother for abandoning him not long after he was born, he also resented his father, if it weren't for his father's suspicion and alcoholism, his mother would not have left him, and he would not have become a child of a single-parent family.

And Chen Xiao exposed a lot of things about him, not only spreading around that he went to the club to be a young master, but also revealing the situation in his family, which made Xue Sheng lose the only thing he has that he has now, even Xue Sheng's belief, which completely ignited the powder keg in Xue Sheng's heart, and he beat Chen Xiao at that time, causing Chen Xiao to be seriously injured and hospitalized, which was just a manifestation before Xue Sheng's psychology completely evolved and distorted.

After he was imprisoned, he was bullied by the cell boss, ridiculed by others, and the other prisoners stood by and watched, and the prison guards did not pay enough attention to it, Xue Sheng was greatly stimulated both physically and mentally, and his distorted psychology was completely transformed, from a prisoner who studied hard and worked hard to reform, to a ruthless murderer, and the death of the cell boss was only the beginning of his complete transformation into a murderer, and it also paved the way for his subsequent continuous killings.

Although for the time being, Xu Lang still doesn't know how Xue Sheng tricked Chen Xiao from S City to TW City, nor how he killed Chen Xiao and the six dead people behind, but Xu Lang knew that Xue Sheng went from one extreme to the other at this time.

When Xue Sheng finished saying these words, he also stopped talking, looked at Xu Lang with an indifferent expression, and said slowly: "Can you give me a cigarette?" ”

Ning Yanran looked at Xue Sheng and found that Xue Sheng was telling what happened before he killed the first person, and he was talking so lightly, as if he was telling someone else's story, which made Ning Yanran a little unacceptable, she really couldn't figure out why Xue Sheng became so extreme, of course, Ning Yanran couldn't figure it out and couldn't blame her entirely, after all, before she came to S City to serve as the captain of the second criminal investigation team, she had been engaged in civilian work in the H Provincial Public Security Department, so naturally she rarely came into contact with this kind of prisoner.

Xu Lang took out a cigarette case from his pocket, took out a cigarette, stood up, came to Xue Sheng, handed the cigarette to Xue Sheng, and then took out a lighter to help Xue Sheng light it.

Xue Sheng lowered his head, held a cigarette, and when he lit the cigarette, he subconsciously blocked the lighter with his hands, in fact, this action was meaningless, because there was no wind in the interrogation room, but he still did it, which shows that Xue Sheng is a very insecure person.

After the cigarette was lit, Xue Sheng raised his head, looked at Xu Lang, and said with a smile, "Thank you." ”

Xu Lang didn't speak, took back the lighter and put it in his pocket, sat back behind the interrogation table, and looked at Xue Sheng with an expressionless face.

"Ahem"

Xue Sheng obviously didn't know how to smoke, and after taking a puff of cigarette, he coughed violently, coughing while continuing to smoke, and then Xue Sheng looked at Xu Lang and said with a smile: "Wait until I finish smoking this cigarette and continue to talk." ”
