At ten o'clock in the morning, Song Wen parked his car on the outside of a red wall. On both sides of the road, tall ginkgo trees were planted. Golden yellow leaves were scattered on the ground. From a distance, the place was bright yellow.

Lu Siyu opened the door, and Song Wen asked, "Did you bring everything?"

Lu Siyu gave a serious grunt, especially touching the gun behind him. Since the last accident, Song Wen has applied for a gun for him in case of emergency.

Song Wen also turned off and got out of the car and looked up.

In front of me is a somewhat outdated school. This is the alma mater where Xia Weiwei studied at that time. The former Nancheng Medical University, which later became the Faculty of Medicine of Nancheng University of Technology.

Ten years ago, Nancheng University of Technology, Nancheng University of Mining, and Nancheng Medical University merged and later became Nancheng University of Technology. The old site of this medical university has been preserved.

Although this school is not the most famous medical institution in Nancheng, it also trained many doctors in its early years. Those medical workers rescued the wounded and worked hard on their posts.Stepping into this campus, Song Wen couldn't help but admire him.

Two people walked to the gate of the school, and there was a middle-aged man who was nearly 50 years old. Although this man was very old, he was in good shape and condition. He wore glasses, and there were some age-old men in the corners of his eyes. Crow's feet, high hairline and a few strands of silver in his hair revealed his age.

The man wore a dark blue trench coat and looked very capable. He greeted him with a smile and asked, "Captain Song? Hello, this is Zheng Huaian. Although I am a vice principal, his surname happens to be Zheng."

"We also have a team leader with the surname Fu." Song Wen had previously contacted President Zheng. He was the vice president of Nancheng Polytechnic in charge of logistics and a senior who was two terms higher than Xia Weifang. "President Zheng, today sorry to bother you."

Then Song Wen pointed to Lu Siyu and said, "This is my colleague, Lu Siyu."

Lu Siyu turned his head and was facing Zheng Huaian. He glanced at him and then lowered his head.

Principal Zheng thought this little policeman was a little bit shy. He was very talkative and didn't see outsiders: "It's not a trouble. We should help the police to provide clues."

Song Wen chatted with him: "President Zheng, I guess many people have looked for you over the years."

Principal Zheng said: "Yes, recently, a Captain Xu came here."

This President Zheng stayed on to teach here after the postgraduate entrance examination, but later transferred to an administrative position. He can be said to be an insider close to Xia Weiqi, so every time he finds this case, he often comes to him. case.With so many people here, Principal Zheng has become accustomed to this.

Song Wen didn't want to talk about Xu Changying's death in duty, and turned the subject away: "Now this case is returned to me to continue the investigation."

Principal Zheng sighed and said: "I didn't expect that such a'celebrity' would appear in the school. To be honest, our school was also tired of her reputation a few years ago, and the number of students dropped sharply in several sessions. I had to rely on subsidies to reduce scores to recruit some poor students. If it were not for the merger of several schools, the source of students would almost become a problem. Fortunately, the school changed its name and got investment. In the past few years, many famous teachers have been invited. The old facilities have also been renovated, and this is getting better."

Then Principal Zheng turned his head: "Two police officers, what do you want to ask?"

Song Wendao: "Principal Zheng, are you familiar with Xia Weiqi?"

Zheng Huai'an said: "It's hard to say that we are very familiar. At that time, there were less than 30 students in a clinical class and very few school girls. Although I enrolled two years earlier than Xia Weiqi, we had some elective courses together. On, so I know her."

Song Wendao: "When we came here, we first wanted to check the list of teachers in the school. The police compiled a list based on the time of the incident that year, that is, the list of teachers and employees in the medical school. We want to know, these teachers What are the personalities and special features of each employee."

Principal Zheng said: "Oh, this year, the relevant people should have been questioned."

When he said this, he took the form and introduced the people on the form one by one. His memory must be more detailed than the record on the form, but when he finished speaking, Lu Siyu was still light. He shook his head slightly.

Among the people he described, more or less, there are some profiling points that are not consistent with Beluga whales.

Principal Zheng sensitively caught their disappointed eyes and asked: "Um, sorry, did I not help you?"

Song Wen put away the list and said, "No, it has been very helpful, and the many details in it may be of great help in the investigation."

Lu Siyu said next to him: "President Zheng, can you take us around the campus?"

Principal Zheng was taken aback: "Where do you want to go shopping?"

Song Wen explained: "It's the places Xia didn't know where you would go when you were in school. We just wandered around and felt the environment of your school."

It was probably the first time that President Zheng saw such a method of investigating a case. Then he said: "Okay, but after more than 20 years have passed, the campus has changed a lot, so I will take you around. "

So Principal Zheng walked ahead, Lu Siyu and Song Wen followed behind him.

As they walked, Principal Zheng pointed out to them: "The campus of this school is not big, and a new campus has been built in the north of the city. You are in front of the teaching building, on the left is the laboratory building, over there is the student dormitory, behind The two floors are the dining hall, the gymnasium and the library on the right... However, these buildings here are of little reference value for you. They are all newly built in recent years, and they have long been completely different from the past."

Lu Siyu followed and watched, Song Wen continued to ask Zheng Huaian: "Well, President Zheng, in your memory, what kind of person is Xia unknown?"

Principal Zheng recalled: "When we went to school, I really didn’t think she was too special. She looked very quiet and beautiful. She often sat at the back of the classroom and spoke very softly, although she was silent. It's not loud, but I remember she was very courageous and her temper was not small."

Song Wen asked, "Are there any specific things?"

Principal Zheng smiled helplessly: "It's been more than 20 years, how can I remember?"

"Then how was her class grade at that time?"

"Your police should have retrieved her transcript? I don't remember the details. After all, I and she are not in the same class. I only remember that she once complained that the English exam was not good. Other... It's not bad. I remember the teacher often praised her back then."

Song Wen asked again: "Then Xia Weiqi almost dropped out of school back then, why?"

Principal Zheng said: "At that time, I was already in graduate school. She didn't come to school for almost a month. She seemed to say something was wrong with her body. Later, when she came back, she became very thin and became a mellow girl. Skinny. I didn't care about these things anymore."

Lu Siyu interrupted their conversation suddenly and pointed to a building in front of him and asked, "Where is it?"

The place is behind the school. It is an inconspicuous building. It can be seen that the building is very old. The bricks and construction methods are all from the last century. On the door, a handful of iron is hung. The lock of the chain.

Principal Zheng helped his glasses: "Oh, ah, that is the old anatomy building. Later, a new anatomy building was built. It was no longer needed there. He kept saying that it was going to be demolished and wanted to build a basketball court for the students. Haven't started it yet."

"Anatomy building?" Lu Siyu read these three words, standing downstairs and looking upstairs.

This is the place where the teacher died, which is the focus of their trip.

"It's the place where medical students dissected the corpses." President Zheng was afraid that he would not understand, so he explained.

Lu Siyu said: "I know, I have studied forensic medicine, and often take anatomy classes." He paused and continued, "However, the rules of forensic anatomy are completely different from those of medical schools. The methods of use and storage of corpses are completely different. , Is also completely different. Generally, complete and high-quality corpse sources are given priority to the medical school, and those in the corners, or even violently dead, decayed, and not required by the medical school, can be used in our turn."

Principal Zheng said, "For us medical students, the corpse is called the general teacher, and it has always been the most scarce resource. The anatomy class is simply the class I remember most. Every time we go to class, we I have to bow deeply to the teacher. I have thought that after I die, instead of cremation, it is better to go back to school so that every student can be assigned a corpse. That is the anatomy teacher’s wish. ..."

Lu Siyu suddenly asked, "Can we go in here and take a look?"

"This... this building hasn't been opened for many years, and the key may not be found." Principal Zheng was slightly embarrassed.

Song Wen said: "It's okay, we can find an unlocker, as long as we can open it." In his words, there is a meaning that we are not in a hurry, and we will not leave if we don't let it look.

"I'll call and ask." Principal Zheng finished speaking, went to the side of the road to make a call, and walked back after a while, "The logistics guy said to help find the keys."

Song Wen nodded, "Then let's go to the cafeteria nearby."

The three of them went around in the cafeteria and returned to the neighborhood again. They saw an old man riding a battery car and handing a bunch of keys to Principal Zheng's hands. Principal Zheng came over with the keys and distinguished it. I chose one of the labels above.

The lock was a bit old, and it shook a few times before opening it with a light click.

"This, I can make an exception to show you, but this place is not a good place." Zheng Huaian looked serious.

Song Wen pretended to inadvertently mentioned: "I remember it was written on the file, it seems that you have had a murder case back then."

Principal Zheng's face was obviously stiff: "That was an accident."

Song Wendao: "Listen to President Zheng, there is a story behind?"

Principal Zheng paused, and then said: "Well, I won't keep you from telling you. This is an accidental death. A teacher named Qiu drank too much and went down to the corpse pool below. I accidentally stepped on the air and fell down. After struggling for a long time, I was drowned. I waited for several days before I was discovered..."

Having said this, he sighed, seemingly unwilling to recall the tragic situation at that time.

Song Wen asked: "Did the family members ask for a strict investigation?"

"The teacher Qiu usually has a bad relationship with his wife. The two have been separated for many years. It took almost three days before I remembered to find someone. I couldn't find it in various places. There was still a class when the body was collected in class, and one of them was found. There is something wrong with the body."

"What did the police say?"

President Zheng knew a little bit, and replied: "Anyone can come to this anatomy building at that time. Professor Qiu also came often, and there was no surveillance video at that time. Formalin was the most suitable for keeping corpses, and the police did not know that he was. When did I fall in, the investigation result came out as an accident. After all, this is not a glorious thing, and the family will not be held accountable, and the school has issued a password to the student."

Song Wen asked: "Why did that professor come to this anatomy building in the middle of the night?"

"Who knows?" There was a helpless expression on Principal Zheng's face. "Maybe he missed something and came back to find it. Maybe he couldn't think about it and wanted to commit suicide. He has been dead for more than 20 years. I am neither the client , It’s not the police, and I don’t know the details."

Principal Zheng took a deep breath after speaking these words, and then dignifiedly opened the heavy door in front of him, and a strange smell suddenly emerged from the door. The smell was formalin mixed with the rotting body. The smell has lasted for so many years.

Song Wen coughed a few times directly by the smell, and Principal Zheng also covered his nose and mouth and frowned.Among the three, only Lu Siyu looked calm as usual. He took out a pair of gloves from his pocket and put it on his hand, then raised his eyes to look at the dark corridor and walked in with his long legs.

Principal Song Wen and Zheng hurriedly followed him.
