No matter what case is investigated, the work of finding and visiting is the hardest, and at the same time one of the most clumsy methods, but no matter how hard, clumsy, and inefficient, the work of finding and visiting is an indispensable part of solving the case.

Now the police in S City and T City are busy for one thing, that is, to investigate Yu Hongxuan's past, and it is a past that is no matter how big or small, this work is nothing for the criminal police, it is not difficult, it just takes some time, but now, what Xu Lang lacks is time, because there are less than 41 hours left before the detention period of 48 hours, and the police of the two cities must take it within this short 41 hours, otherwise, there will be a lot of variables.

Generally, to investigate a person's past, the first thing to investigate is the person's bits and pieces in the recent period, after all, the closer the time, the easier it is to investigate, which is also a common sense that all people who are criminal police officers know, however, when they investigated Yu Hongxuan, they encountered an extremely abnormal situation, since Yu Hongxuan finished high school and went to college abroad, Yu Hongxuan has no archives, no one knows where he went, no one knows what he is doing, I don't even know what he's doing.

The only people who knew all this were Yu Hongxuan's relatives, that is, Yu Zhen and Lu Qinxuan, however, these two people were also dead, and the corpses were still lying on the cold dissecting table by the forensic doctor with a scalpel, and it was impossible for the dead to speak.

Mao Wenshi and the others felt that Yu Zhen's house and conducted a careful search of the deceased's home when they conducted a scene investigation, but they did not find a diary, no photos, and no items or records related to Yu Hongxuan.

Yu Zhen and Lu Qinxuan are dead, it is impossible to come back to life, tell the police about Hongxuan, then you can only learn about the situation through Yu Hongxuan's relatives and friends, so Mao Wenshi arranged for his subordinates to contact relatives who are related to Yu Hongxuan's family, however, the result once again disappointed everyone.

Since the car accident seventeen years ago, Yu Tian died, Yu Zhen retired, and Lu Qinxuan was paralyzed again, and the relatives who had often interacted with Yu Zhen's family before slowly began to become estranged, they did this for a very simple reason, that is, they were afraid that Yu Zhen would open his mouth to borrow money, after all, Yu Tian drove and killed someone, and afterwards the relevant departments judged that Yu Tian was fully responsible, although Yu Tian died, but his family had to pay a large amount of compensation to the family of the deceased, and Lu Qinxuan needed surgery at that time, and also needed a large amount of money, It is human instinct to seek advantages and avoid disadvantages, in the past, when Yu Zhen's family did not have an accident, those relatives who often came to visit the door, after learning about Yu Tian's affairs, also went to the hospital to visit Lu Qinxuan a few times, and after saying some words that did not hurt or itch, they never went again, especially when the final verdict came out, these relatives seemed to have evaporated from the world, and they never contacted Yu Zhen's family again, as for how Yu Zhen's family has lived over the years, whether Lu Qinxuan's legs are good, Where Yu Hongxuan went to school or worked, when the police asked, they didn't know.

At that time, the police officers who went to Yu Zhen and their relatives to inquire and investigate, after learning the result, were very depressed, when they told them the news of Yu Zhen and Lu Qinxuan's death, these people also showed very indifference, it seemed that the death was just a person who had nothing to do with them, no grief, no anger, and no sympathy, which made the police officers very angry, but they couldn't do anything but anger, after all, this was their own private matter, and the police had no right to interfere.

When you have money, power and status, those relatives who can't fight with you will come to you, once something happens to you, these people will run faster than anyone else.

For this result, Xu Lang and Mao Wenshi were also very angry after learning about it, but they had already been mentally prepared, after all, it was not the first time they had encountered similar things, in fact, such things happened all the time, Xu Lang and they were used to it.

Since there was no result from Yu Hongxuan's relatives, Mao Wenshi and they had to find another way, they checked forward from the blank place where Yu Hongxuan's archives appeared eight years ago, first of all, they found the high school where Yu Hongxuan once studied.

In T University Key High School, the police met the principal of the school and the head teacher who had taught too Hongxuan, and the police got Yu Hongxuan's former school file in their hands, the information on the file is limited, except for showing that Yu Hongxuan is a very smart person with excellent academic performance, there are not too many other useful clues, the only thing worth noting is that all the teachers' evaluations of Hongxuan will be written, this is a taciturn child.

The police questioned the head teacher of Yu Hongxuan High School, according to the memories of the head teacher, he remembered that Yu Hongxuan was a child who studied very hard and hard, usually in addition to studying or studying, he rarely talked to people, and he was unwilling to communicate with anyone, in the three years of high school, he had almost no friends, and at the end of the inquiry, the head teacher told the police that when Yu Hongxuan was in high school, he was a day student, not a boarding student, and he rented a house next to the school, as for where he rented it, he was also unclear, In addition, after so many years, there are so many students he has brought with him that he can't remember them at all.

The police took the files of Yu Hongxuan's high school days, and found Yu Hongxuan's junior high school class teacher, but unfortunately, the head teacher who taught too Hongxuan had already retired, and he had passed away two years ago, and the police had no choice but to find the school to get the files of Yu Hongxuan's junior high school period, and then left.

Yu Hongxuan's junior high school files are no different from his high school files, and all the teachers' evaluations for him are that he studies hard, has excellent grades, and is a little taciturn, these comments are nothing special.

Just when the police were about to look for the teacher of Yu Hongxuan Primary School, they unexpectedly learned that Yu Hongxuan had studied in two primary schools, one primary school was a key primary school in T City, Yu Hongxuan was in the experimental primary school in T City before he went to the third grade of primary school, and the primary school was not far from the Third People's Hospital in T City. It was also burned during a previous school clean-up file, and the police had to return disappointed.

Yu Hongxuan's second primary school is in Fengcheng Township, when the police came here, they found that the previous primary school had been merged into another primary school ten years ago because of planning problems, as for the archives or something, there is no more, but, fortunately, the police still found the primary school teacher who taught too Hongxuan, this teacher has retired, and the police also got the news unexpectedly in the school.

When the police found the teacher, the old man recalled for a long time, only to vaguely remember some fragments, the old man told the police that Yu Hongxuan was when he was nine years old, came to the primary school to study, because he was a transfer student, so, as Yu Hongxuan's homeroom teacher at that time, he was still very concerned about Hongxuan, and the old man still remembered the reason for Yu Hongxuan's transfer, because it was a white-haired old man who sent Yu Hongxuan to school at that time, that is, Yu Zhen.

The old man recalled that Yu Hongxuan used to go to school in the urban area, and he went to a key primary school, so his cultural foundation was very good, and after transferring to school here, he still performed very well, however, Yu Hongxuan seemed to be very taciturn after the accident at home, and he didn't want to talk to anyone. After all, children are only in elementary school, so what can they know, at most, is just a joke.

When Yu Hongxuan was transferred here to school, he was often bullied, but Yu Hongxuan was very stubborn, neither telling the teacher, nor telling the parents, not saying anything, but, once, when he was out of school, Yu Hongxuan had a fight with all the children who bullied him, and the fight was very serious and bloody, Yu Hongxuan fought with seven or eight children alone, he was beaten with a blue nose and swollen face, and two front teeth were knocked out, but he still relied on that intelligence, beat all the children who bullied him, and in the end, it was because the other children ran back and told their parents that the adults came, so that the two sides of the fight were separated.

This incident was still very sensational at the time, and the parents of the children who were injured by Yu Hongxuan at that time all went to school, but when they saw Yu Zhen and learned about Yu Hongxuan's family situation, and then under the mediation of the school, this matter was over, but since then, no child dares to provoke Yu Hongxuan, and no child is willing to play with the guy who is like a stuffy gourd and ruthless like a madman, so Yu Hongxuan didn't have any friends from elementary school to high school.

When the police officers who went out to investigate and visit Yu Hongxuan's previous archives came back, Xu Lang, Mao Wenshi and Ning Yanran began to analyze Yu Hongxuan's character after seeing these materials.

"From the archives of these schools, it can be seen that Yu Hongxuan is a taciturn person, and this kind of person who is unwilling to talk and communicate with others is divided into two situations, one is a person with extreme inferiority, he is like a turtle, habitually closing himself in his small room, and the other is a person with strong self-esteem, this kind of person is like a hedgehog, they have a very strong sense of territory, and they don't want others to get close to them, once they get close, they will be pricked with blood." Ning Yanran looked at the information and said.

"What kind of situation do you think Yu Hongxuan belongs to?" Xu Lang looked at Ning Yanran and asked.

Hearing Xu Lang's question, Mao Wenshi didn't react, Ning Yanran was like seeing a ghost during the day, she heard Xu Lang ask her opinion for the first time, she used to ask Xu Lang's opinion, but when she saw Xu Lang's deep eyes, Ning Yanran didn't ask the question to her mouth, but said directly: "I think Yu Hongxuan belongs to the second situation, a person with strong self-esteem." ”

After Xu Lang listened, he nodded, and did not say whether Ning Yanran's analysis was right or wrong, but continued to ask: "Except for Yu Hongxuan who is a person with strong self-esteem, is there anything else?" ”

"He's a very smart guy, and that's something you can see from his report card from elementary school to high school, where he consistently tops his class in exams, and he's been in the top three." Ning Yanran continued.

Xu Lang was not surprised that Yu Hongxuan was a person with a high IQ, if Yu Hongxuan was not a person with a high IQ, he would not let Xu Lang until now, there is no direct evidence to prove that Jin Enpei was killed by him, and it is impossible to find Jin Enpei's body until now.

Ning Yanran took one of the interrogation records among the many materials and said: "At the same time, he is a ruthless person, and he is also a person with a strong sense of revenge. ”

Xu Lang and Mao Wenshi have roughly read these materials, Xu Lang took the interrogation record that Ning Yanran picked up and looked at it, and found that it was the testimony of the teacher of Yu Hongxuan Primary School, Xu Lang nodded after reading it carefully, and agreed with Ning Yanran's analysis.

Ning Yanran saw that Xu Lang actually agreed with her analysis, Ning Yanran was sincerely happy in her heart, this was even happier than when she scored 100 points in the school exam, Ning Yanran herself didn't know why she had this emotion.

Xu Lang, Mao Wenshi, and Ning Yanran came to the conclusion after some analysis that Yu Hongxuan is a person with high intelligence, high emotional intelligence, strong self-esteem, and even some conceit, in addition, Yu Hongxuan is still a person with a strong sense of revenge, this kind of person, if he can't get the right guidance, once he embarks on the road of crime, the harm he causes is not as simple as the harm caused by ordinary criminals, in other words, a person like Yu Hongxuan, unless he doesn't commit a crime, once he commits a crime, it is a big case, And there will be very little evidence and clues left for the police, which can be seen from the case of his murder of Jin Enpei.

Yu Hongxuan's character has been analyzed, but it is still not of much help to find the evidence that he killed Jin Enpei, and after Yu Hongxuan graduated from high school, all his information is gone, blank, and now, what the police want to figure out is that in the past eight years, where Yu Hongxuan went, what he did, and how he changed from a man to a woman, this is the point.

Just when Xu Lang and the others were at a loss, Mao Wenshi suddenly remembered someone, he thought about it, and said, "There may be someone who will know about Yu Hongxuan's situation." ”

"Who?"

"Who?"

Xu Lang and Ning Yanran raised their heads in unison and asked in unison.

Mao Wenshi saw Xu Lang and Ning Yanran's straight eyes, Rao is he was also a little unnatural by the two of them, and after he coughed, he said, "Ruan Kangan, the director of the Third People's Hospital." ”

"Nguyen Kang An."

Hearing Mao Wenshi mention this name, Ning Yanran didn't feel anything, she just felt that she had heard this name somewhere, but she couldn't remember it for a while, but Xu Lang remembered it all of a sudden, Ruan Kangan was the president of the Third People's Hospital of T City, he and Yu Zhen were college classmates, and the two worked together in the Third People's Hospital, and later, Yu Zhen became the director of surgery of the hospital, and he became the president, when Yu Tian was alive, he also worked in the Third People's Hospital, Yu Tian and Ruan Kangan are also teachers and friends, after Yu Tian's accident, the person who has been busy with Yu Zhen is this person, maybe he really knows something.

Now that Yu Zhen is dead and Lu Qinxuan is dead, the only one who knows where Yu Hongxuan has gone in the past eight years is Ruan Kangan, and, according to the police investigation, Yu Hongxuan's study abroad was still successful under Ruan Kangan's operation, since Yu Hongxuan did not go abroad, it is impossible for Ruan Kangan, as a party, not to know.

Thinking of this, Xu Lang and Mao Wenshi glanced at each other, and the two of them could see what the other was thinking from each other's eyes, so Xu Lang and Mao Wenshi looked at each other and smiled, Xu Lang stood up and said, "Let's go, let's go and meet this dean." ”

Mao Wenshi nodded, Xu Lang's identity is special, Ning Yanran is a police officer from S City, handling cases in T City, although Ning Yanran has the same position as Mao Wenshi, but it is still more convenient for Mao Wenshi, who is half a landlord, to investigate the case on his own territory, so Mao Wenshi took Xu Lang to the Third People's Hospital, while Ning Yanran continued to investigate other things, in fact, Ning Yanran has a lot to do, but most of them need to wait, Ning Yanran had to go to the interrogation room and where Yu Hongxuan soaked mushrooms.

It's just that when Yu Hongxuan saw Ning Yanran, she still didn't say a word, just a mocking smile on the corner of her mouth, and her eyes were full of provocation and disdain to look at Ning Yanran, Ning Yanran was not angry, she just asked according to the process, she asked a few questions, and after not getting a reply, Ning Yanran gave up asking, and began to start the mode of staring at Yu Hongxuan again.

Mao Wenshi drove, Xu Lang sat in the co-pilot, and the two of them drove to the Third People's Hospital, Mao Wenshi had already asked the hospital before he went, and learned that Ruan Kangan was in the hospital, so that they could save a lot of trouble, as for whether there would be any result of asking, it would depend on Xu Lang and Mao Wenshi.
