On the surface, the latest batch of human specimens was obtained from donors from off-campus hospitals, but when Shi Hao and the hospital were suitable, they found that there was an extra human specimen. The hospital showed that it had provided two specimens to the medical school, one of which was a normal human specimen donated by an elderly man after his death, and the other was a rectal cancer patient who signed the donation before his death, hoping to study his body through guò to obtain better methods and drugs for the treatment of rectal cancer. The two corpses had obvious features, so the three investigators from the medical school who were present immediately denied the possibility that the corpse in the autopsy room could come from the above two corpse sources, first of all, the old man was an old smoker with 40 years of smoke, but the lungs of the corpse in the autopsy room did not show dark black pathological features, on the contrary, the lungs did not have any symptoms indicating that the corpse had a habit of smoking; Although the corpse was carefully treated before being presented to the students, some traces could be found by careful observation, the corpse's colon was diseased, which was poisoning death, and some poisons (such as inorganic mercury compounds) were excreted through the colon and the lesional reaction, but the hospital immediately denied the possibility that the corpse was the body of a rectal cancer patient, the rectal cancer donor had an anorectal fistula operation before his death, and the patient had been hospitalized until his death, and the drugs used were provided by the hospital. However, there is no component of inorganic mercury in the patient's medication. There were no surgical marks on the rectal part of the corpse, and there were no obvious features of cancer metastasis in the liver, so the hospital denied that the body in the autopsy room was from the donor with rectal cancer.

Ruling out two possible sources of corpses, Team Xiao speculated that this corpse might be the body of the wanderer who unfortunately died in Shiyàn, and when the school lacked human specimens, they used the reason of a donor of 100 million yuan as a cover, and sent it to the dissection room together with the other two corpses for students to observe and study. Li Jing and Mr. Lu agreed with the idea of the school team, so Team Xiao and his colleagues deliberately went to many places to find another wanderer who had successfully escaped from the accident that broke the news to the media about the medical school's accident. Because of the impact of that incident, some of the leaders of the medical school ostensibly went to visit the wanderer, but in fact went to solve their so-called troubles. Because of public opinion, it was unlikely that the wanderer would be killed directly, so they sent him to a psychiatric hospital in another city far away from here and imprisoned him.

When I first asked the school board that was dealing with the matter at the time. The person concerned has been keeping his mouth shut, unable to read the text, and in a hurry to confirm the identity of the body, Teacher Lu asked to investigate the whereabouts of the teaching director Feng Xin during that time. By the way, several hospitals that are usually closely connected with the academy were also the focus of investigation, and another wanderer was finally found in a psychiatric sanatorium that a medical school had cooperated with. On the other hand, Shi Hao's investigation revealed that Feng Xin, the director of education, had indeed driven to that city when the incident occurred, but he was afraid that the train ticket would leave evidence, so he chose to drive there, and the car was from the school. At that time, the registered car user was Feng Xin, and the visitor to the nursing home registered by his nephew was also Feng Xin, so it can be speculated that Feng Xin went to that sanatorium at that time, and then there was no news of the wanderer. Later, when the party school felt a sanatorium for them, they found the wanderer.

After the director of the psychiatric sanatorium knew that something had happened to the medical school, he immediately isolated the homeless people who were sent here separately, and when he was about to confirm with the medical school, the Xiao team had already brought people to find someone. Fortunately, because of the short time they were sent to the nursing home, the treatment at the hospital was also cautious. No damage was done to the wanderer's brain tissue, and after police professionals tested him to confirm his ability to identify, Team Xiao took him to see the body. The wanderer confirms that the deceased is his companion at the first glance of the corpse, and even after blocking his face between the three corpses, the wanderer can still accurately identify which one is his companion's corpse. The wanderer said that his companion's second toe was significantly shorter than the others, which was easily recognizable even when the face was blocked.

After confirming the identity of the deceased, Team Xiao unconsciously asked the wanderer if he recognized a person named Maoya, and the wanderer's hand subconsciously wiped his chin, then shook his head and said that he didn't know. But his subconscious work in the Year of Buddha caught the attention of Teacher Lu, and this action was an obvious hint of lying. Children will habitually cover their mouths with their hands when lying, while adults will abandon this action and instead pull the hair from the side of their mouth or other actions around the mouth. So Mr. Lu immediately speculated that the wanderer was lying, and he must know Mao Ya.

If this wanderer knows Maoa. Could it be that he asked Maoya to avenge him? Mr. Lu does not agree with this speculation, he thinks that the wanderer may have been through the news or was inadvertently revealed during the whole process of identifying the corpse, Mao Ya may be the murderer who used the corpse to cause the serial murder on campus, and he thought that Mao Ya was avenging them and was unwilling to reveal what he knew about Mao Ya. The main issue now should be to understand what channels connect two people who have nothing to do with it. For this reason, Team Xiao sent Shi Hao and Li Jing to Mao Ya's former alma mater to learn about Mao Ya's situation after she went to school.

The other medical school they were going to visit was actually in another neighboring city, not very far away, but because it was later merged with other schools. Some of the old professors have already moved to other schools to teach, and there are not many faculty members who can remember Mao's class. finally found an old professor, but he was not Mao Ya's teacher at the time, but he still had some impression of Mao Ya.

When Mao Ya was mentioned, the old professor pursed his lips and said that Mao Ya was talented but not doing his job, and if he had been more attentive in his studies at that time, he might not have dropped out of school halfway. Li Jing remembers that when he interviewed the villager with the same name as Wang Qing before, he said that Mao Ya's academic performance had always been very good, so how could he drop out of school halfway. The reason for this is that the old professor recalled for a long time before saying that when Mao Ya first arrived at the school, although he could feel that he didn't seem to like the courses of the Mountain Medical College very much, his grades in the school were still excellent with his extraordinary talent. But the turning point seems to be in the second half of his freshman year, I heard that something happened to his family, and when he came back from dealing with family affairs, his grades plummeted, and then he went home a few times, and every time he came back from home, his grades would fall even further, and finally his grades became very bad and he was dropped out of school. Knowing that when she dropped out, the old professor heard that Mao Ya returned to his hometown at that time because his father, who was a doctor, was beaten to death by the family of a troublesome patient, so he was disappointed in the industry, so his grades have been declining since he came back. The old professor expressed between the lines that he was sorry that Mao Ya could not continue his studies. The angel who could save lives gave up his mission like this, and the old professor was full of regret. Li Jing asked the old professor about Mao Ya's situation, but the old professor shook his head and said that he didn't know, and asked them to go and see the school's reference room. It may help, but since it is a student who has been dissuaded from school, it also reminds Li Jing not to have too much hope.

Li Jing and the others were lucky, although the medical school had been swallowed up by another larger medical school, but the original information was still very well kept. With the efforts of Shi Hao and Li Jing, they finally found Mao Ya's information back then, because he was persuaded to quit halfway, so the student registration information was not perfect, but the only remaining information did confirm the old professor's words, Mao Ya's studies were still quite good in the year of admission, and it is also a fact that his grades were regressing in the posture of Waterloo. At the end of the information, Mao Ya took the file and transferred to a junior college, majoring in computer science.

Originally, I wanted to go to the junior college to ask about the situation again, but Li Jing suddenly had a bad premonition. He recalled the old professor's words repeatedly, and suddenly a light flashed in his mind, and then a creepy conjecture suddenly collapsed into his mind, he asked Shi Hao if he remembered when the old professor said that Mao Ya's changes began, Shi Hao said impatiently that the old professor had said several times that it was a change in the second half of the second semester of his freshman year, and before he finished speaking, Shi Hao suddenly stopped, and looked at Li Jing with his mouth half open, he seemed to know Li Jing's thoughts. But he still looked at Li Jing unconvincedly, didn't Mr. Lu deny Li Jing's statement before?

Li Jing asked Shi Hao to retrieve all of Mao Ya's identity information from the identity verification database. Including the identity information of the people close to him, Mao Ya's marital status shows that he is divorced and has no children. Mao Ya divorced his wife this summer, and there is no other record of him in his identity information. After that, Mauya quit his job and didn't even pay for health insurance, and his profile was blank after the summer. He left the house after marriage, and now even if he goes to find him, it will take a lot of effort.

Li Jing and Shi Hao analyzed. The change in Mao Yaqing's xù may have started this summer, and the second blow he received after the divorce may have made him have murderous intent again after seeing the son of the enemy who killed his father, but why he killed the two children, in addition to objective reasons, Li Jing still had no clue at the time, and how he met the wanderer, Li Jing and they did not find any useful clues.

They went to meet Team Xiao and Teacher Lu with their own ideas, and Li Jing boldly expressed his guess, he thought that Mao Ya, who was now unconcerned, might eventually commit suicide in this school, because according to his previous speculation, the order of death of each deceased person before was in a state of complete thought with the order in which they changed, and He Wei was the transformation that occurred at the end of his senior year, so he was the first victim to be killed by Mao Ya; After that, there is Li Wei, who was the second to be killed in the transformation that took place in the early part of her junior year; Then there is the teaching director Feng Xin, because of his father's death and his grades regressed in his sophomore year, so they found the number two in his jacket pocket, in fact, he was the third victim to be killed, the same as Li Jing speculated, the order of the murderer's murder began with their own change The order is diametrically opposite, then the last victim, his change occurred in the freshman year, that is, the person who represents one who is likely to educate the murderer, is likely to be the murderer himself - Mao Ya.

Teacher Lu asked Li Jing why he could believe that Mao Ya would kill him, Li Jing said the information that Shi Hao found out, Li Jing thought that Mao Ya now has no concern in this world, since he killed the first victim, he has planned his own suicide, and the only thing he really resents is himself from beginning to end.

When he was in college, he studied medicine at his father's behest of the people, but from an early age, he was confronted with incomprehensible shoving and swearing instead of the respect of the villagers for his father, the only doctor in the village. When he was forced to study medicine, his father was killed by the patient's family, and at that time, no one enlightened this child who had lived in the shadow of fear since he was a child, and even the villagers hid the truth from the police because they were afraid of the patient's family, and justice could not be served. The lack of heart finally led Mao Ya to a desperate path of revenge, and at that time Mao Ya had just been expelled from medical school, under all kinds of pressure. He chose to take revenge on Feng Xin's father, the murderer who killed his father. And this revenge released his long-suppressed heart for the first time, and also relieved the pain after the loss of his loved ones. In the years that followed, he studied computer maintenance. lived a life contrary to what his father had envisioned. And Feng Xin's father's case has not been solved, and he has been at large, this life lasted for more than ten years, with the breakdown of the marriage, Mao Ya once again returned to the dark moment. And at this time, he happened to meet Feng Xin, a member of the family who led his entire tragic life, and the fire of his anger was ignited again, and he attributed all the faults of his life to this man. Like many serial killers, Mao Yatong guò got inner satisfaction from killing people, and when he recalled the feeling of being relieved and released when he killed Feng Xin's father, he should have had murderous intent towards Feng Xin at that time, so at first he just wanted to experience this feeling again, and then when he pretended to be a fellow villager and infiltrated the school to repair the camera, he knew the big secret inside the school.

And at that time. The teachings he received from his father about medical ethics from an early age made him immediately disgusted with the school's practices, and then he changed his entire murder plan. The school's irresponsible attitude towards the real person stimulated Mao Ya and reminded him of his father's teachings, and the participation of Feng Xin, the director of education, gave him the illusion of a reappearance of the past, which he had never witnessed. He unconsciously mistook the dead wanderer for his father and combined the fates of the two, and Feng Xin represented the person who killed his father by mistake in this new death, while He Wei and Li Wei represented those who concealed the truth in order to protect themselves. At that time, the double stimulation (divorce and the reappearance of the fantasy father's death) left Maoya's mind completely confused.

Pure confusion. made him decide to avenge his father, in fact, when Li Jing found Mao Ya's ex-wife again, his ex-wife said that the reason for the divorce at that time was because Mao Ya had let her have many abortions but never said the reason, and even refused to live with her as a couple until the divorce. Mao Ya's ex-wife said that Mao Ya was always immersed in a deep melancholy when she mentioned her children. These reasons may be a kind of self-blame in Mao Ya's heart for not being able to save her father's life, or a kind of grief that she can't do anything in the face of her father's corpse. So when he saw something similar repeating itself in front of his eyes, he uncontrollably released his inner self-blame and decided to avenge his father. And the escaped wanderer met Mao Ya at this time, and then the wanderer was captured, which made Mao Ya firmly believe that he was breeding with his father's death scene again. The wanderers who were captured were treated as the villagers who had been retaliated against for telling him the truth. He completely overlapped the two scenes, killing He Wei and Li Wei, the two victims, was revenge for the villagers who concealed the truth back then; Killing Feng Xin is revenge for killing her husband and enemy, and killing yourself at the last step is a punishment for her powerless self back then.

At the same time, when he took revenge, he regarded the public in the school as the police officers who participated in the investigation back then, and he wanted to make all the truth public, and Maoya's later experience in computer science also allowed him to hide himself well and bring his so-called 'justice' to justice. He is proficient in computer design, and he also learned about the general situation of the people in the real building during the repair of the camera in the real building, and undertook the business of privately copying the access control card at a very low price, and got the access control card of the student in the real building with his own size, and then he could easily hide his identity in the later crime. The team speculated that when the security captain first found him, he deliberately smashed the disinfectant bottle to attract attention, and after verifying his identity, the security captain naturally removed his vigilance from him, so that he would not arouse suspicion when he reappeared in any corner of the campus. After that, he used the excuse of knowing the truth to ask the victim out and find a way to kill him, his father was a doctor, and he also had medical school experience, his size advantage and this medical knowledge allowed him to quickly put his opponent to death without being noticed

Later, during a conversation with the wanderer, when Shaw told him that his 'so-called' benefactor might commit suicide, the wanderer was shocked and finally couldn't help but tell the police the location of their first meeting. Li Jing finally speculated that Mao Ya found him on TV when he learned that the Wanderer had exposed the medical school scandal, and the Wanderer recalled that Mao Ya's gratitude to him at that time even made him feel a little flattered. But the wanderer didn't think too much about it at that time, and when he was sent to the mental sanatorium later, when he learned about the murder on TV, the wanderer connected the two things, because he wanted to avenge his companions, the wanderer never revealed to the police that he knew Maoya, but he didn't know, from the details of his expression, those psychoanalysts present had a rough understanding of the friendship between them.

According to the clues provided by the wanderer, the Xiao team finally found Mao Ya who looked not in good shape in the basement of a dilapidated and dangerous building, he was really writing something on the computer with a pale face, and when he saw someone breaking in, he suddenly laughed and said, 'It's finally time to wait for this moment', and then fell to the ground with a 'bang'. He checked his computer and found that it was an unfinished letter with the evil truth that the medical school had tried to bury.

Teacher Lu looked at Mao Ya who was setting up the ambulance on the table, shook his head, and didn't say anything, Li Jing knew that Teacher Lu was sighing in his heart that this man finally chose to understand his father who was following in another world this time, he was too desperate to insult the meaning of life in the most extreme and wrong way.

When Li Jing graduated, Mr. Lu once deliberately looked for Li Jing, and he said to Li Jing at the end of that dinner: Life is a self-redemption for oneself, and the mission of doctors for those who cannot complete self-redemption is to heal the darkness in their hearts and help them complete their self-salvation.

"Did you do it?" I asked Li Jing.

Li Jing flicked my head: "I don't know if I helped them heal their psychological pain, but I know that I have cured your idiocy." ”

"Nasty." I had a falling out with Li Jing, and although I didn't know what Li Jing's medical skills had reached, I always felt that the patients who were able to meet him should have smelled the sunshine like me. (To be continued.) )
