Lin Huan quickly said, "Xu Xu, calm down."

"I know what you want to ask, why don't you ask me why I didn't call the police?!" Xu Xu seemed to break free from the restraint chair, and said angrily, "What happened after I called the police?! Go through what happened seven years ago again?! Run away again One more time?! Change another place to live again?! Even if you catch him, the crime of rape is only ten years! If you behave well, you can get a reduced sentence, and he can continue to live after being locked up for four or five years! But what about me? ! What should I do?! What else can I do?!"

Yan Lan swiped her hand back and forth on the table a few times, and after a while Qiao Chen opened the door and came in to change Yan Lan out.

Ten minutes later, Yan Lan pushed open the door of the observation room. Su Xing was still in the room and was about to stand up when he saw him coming in. Yan Lan waved his hand to signal him to sit down, and then stood at the door.

Su Xing asked, "Why doesn't Team Yan sit down?"

"I just smoked."

"It's okay, Captain Yan, sit down."

Yan Lan didn't speak or move, she leaned against the wall by the door and looked towards the interrogation room on the other side.

Qiao Chen asked, "How did you know Zhang Mingzhi?"

"Lu Huizi told me." Xu Xu lowered her head and said, "After we got to know Xie Yao, Lu Huizi told me that she had a school girl who was bullied by her father since she was a child, but she didn't tell me the school girl's name. I know that Lu Huizi went to Lingyan No. [-] Middle School in both junior and senior high schools. I just met a younger brother at HKUST who also graduated from Lingyan No. [-] Middle School, so I asked him. I didn’t expect that he and Zhang Jiayi were classmates. Well, I also learned about Zhang Mingzhi from him. An old man like Zhang Mingzhi is easy to lie to, and after a few times, the sperm got into his head and wanted to sleep with me, so I tricked him into my house and killed him."

Qiao Chen continued to ask: "You said you met Zhang Jiayi's classmate at HKUST? What's his name?"

"Qian Peng."

"Why did he tell you this?"

"He... heh, he wants to chase me."

Yan Lan turned to look at Su Xing, and asked, "Has she finished explaining about Duan Zhuo?"

Su Xing nodded: "Duan Zhuo got drunk that night and regarded her as his ex-girlfriend, so he didn't remember her at all. Later Xu Xu approached Duan Zhuo several times, and Duan Zhuo thought Xu Xu was interested in him. At that time Xu Xu had already decided to take revenge, she changed her hairstyle, bought mobile wifi and a new SIM card, registered on WeChat and started fishing."

"What about Luo Pingwen?"

"When she was out of the clinic, she met a girl from the University of Science and Technology who came to see the doctor."

"Isn't she an orthopedic doctor?"

"Yes." Su Xing lowered his voice involuntarily, "I played too much, that girl's trapezium was broken."

"What bone?"

Su Xing explained: "It's a bone in the hand, one of the metacarpal bones."

"Broken palm?"

"It's okay to understand in this way." Su Xing said, "When asking about the medical history, she would always ask how she was injured. The girl hesitated until the end and said that she was injured by the teacher on the bed. Xu Xu paid attention, Luo Pingwen was found."

In the interrogation room, Qiao Chen asked about Jiang Hai, but Xu Xu was silent again at this moment.

Qiao Chen looked at Xu Xu and said, "We already have conclusive evidence to prove that you are related to Jiang Hai's death. You are wasting your time if you don't speak now. Whether you killed one person or five people, you have committed a deliberate crime." Homicide, the crime you committed against Duan Zhuo and the other four is considered serious, if you don't cooperate with the police now, the most severe punishment awaits you."

Yan Lan knew that Qiao Chen had started a psychological battle with Xu Xu. The evidence they had so far could not prove that Xu Xu killed Jiang Hai. There was no monitoring, no fingerprints, and no crime scene.However, Xu Xu's psychological defense is not strong. Long-term psychological warfare and repeated interrogations are enough to expose her flaws. It is only a matter of time before she confesses.

At this moment, Su Xing took out his mobile phone and quickly pressed a few words.Immediately afterwards, Lin Huan in the interrogation room said, "The simulation laboratory on the 21st floor of the second teaching building of the Medical University."

Xu Xu showed an expression of disbelief.

Yan Lan asked, "How do you know?"

"I guessed right." Su Xing took a long breath and said, "Xu Xu didn't bring Jiang Hai home, and the head injuries of the next few deceased were the same as Jiang Hai's. It was caused by oxygen cylinders, so the first scene of Jiang Hai’s death could only be in a place that also had oxygen cylinders. Jiang Hai was the courier responsible for the delivery near the Medical University, so he had no reason to go to the Second Hospital, more than 30 kilometers away from the Medical University. And Xu Xu is unlikely to make an unnecessary move to kill Jiang Haiyue in the hospital and bring him back to the Medical University. The most likely thing is to throw the body nearby after the killing of the Medical University. Fortunately, the Medical University only has the simulation laboratory on the 21st floor of the second teaching. That kind of oxygen cylinder, otherwise I would never have thought of it."

"Looks like I'm going to visit your school again." Yan Lan opened the door, "Let's go, Doctor Su."

No matter how late the medical school is on vacation, it will not be able to detain students until the end of July. At this time, there are only a few students in the school, and the second teaching has been locked because there are valuable instruments and equipment inside.

After greeting the school, Su Xing led a group of people into the Second Teaching.

As soon as he entered the building, Sun Mingrui tugged at his clothes involuntarily: "Su, why is your school so spooky?"

Su Xing said with a smile: "Brother Rui, you are exaggerating. You didn't feel eerie when you were at Xu Xu's house in the morning."

"It's really different!" Sun Mingrui said solemnly, "Xu Xu's house is just disgusting, and your school feels really spooky. I felt it last night, but I always thought it was because the temperature was low at night, but just now I feel a chill in here."

Su Xing: "Is there? Are you psychological?"

"Isn't there? It's really cold! Look, I've got goosebumps!"

Yan Lan patted Sun Mingrui's outstretched arm, and said: "If you continue to be so poor, this year's party will let you have a cross talk with Fatty, and let you two talk once."

Sun Mingrui: "Team Yan, don't tell me, I really learned cross talk when I was young!"

Su Xing pushed Sun Mingrui into the elevator and said, "Okay Brother Rui, the elevator is here, hurry up!"

Yan Lan followed into the elevator and saw that Su Xing pressed the button for 20. Su Xing explained: "The structure of the second teaching building is rather strange. Below the 10th floor is the teaching area. From 11 to 20 are the administrative office area and the teacher's office. 21 Above the first floor is the simulation laboratory. All kinds of equipment and instruments in the simulation laboratory are very expensive. In order to prevent accidental entry, the external elevators only go to the 20th floor. "

Sun Mingrui turned on the Tucao mode: "What kind of arrangement is this? The elevator must not be crowded when you catch up with the group class?"

"Elevator grabbing is a major feature of our school." Su Xing explained with a smile, "In the beginning, the 1st to 15th floors of the second teaching building were teaching buildings, and the upper floors were offices. Later, with the expansion of enrollment, more students and more equipment Too much, but the school is so big, so we compressed the teacher’s office area, moved the equipment up, built a few small second floors, and separated the animal experiment building and the anatomy building separately, which was barely enough .”

Yan Lan: "At any rate, it's a university directly under the Provincial Department of Education. Why is it so shabby?"

"The money is all spent on buying equipment." Su Xing said, "Be careful when you go up to the 21st floor. Any equipment costs tens of thousands, and the expensive ones even cost eight figures."

Sun Mingrui sighed: "Who would have thought that such a small school has trained more than half of the medical workers in our city!"

Su Xing smiled: "It will be fine in the future. I heard that the nail households occupying the land at the back have moved out, and the future master's and doctoral students and clinical students will all move to the new building at the back for classes."

Sun Mingrui shook his head and said, "Is this the same thing... Renovate as soon as you graduate from your alma mater?"

"That's right." Su Xing said with a smile.

Yan Lan watched the two of them talking back and forth, and realized that Su Xing was not so polite to everyone. He was obviously much more relaxed when chatting with Sun Mingrui than when talking to himself. There is more youthful flavor in the tone of voice.

Su Xing led them to change the elevator and go straight up to the 21st floor. After getting out of the elevator, Sun Mingrui clicked his tongue repeatedly: "Isn't this a hospital?"

Su Xing: "Yes, they are all decorated according to the standard of the hospital. There are wards, dispensing rooms, and equipment rooms, just to simulate the working environment in the hospital."

After several small staff in the trace room fixed the fingerprints on the object at the door, Su Xing put on his shoe covers and gloves, walked to the door of a simulated operating room, lifted his foot and stepped on the pedal next to the door, and the electric The door slowly slid to the sides, Su Xing signaled Yan Lan and Sun Mingrui to enter the room first.

This is a very standard operating room, with ventilators beside the operating bed, ECG monitoring and equipment carts, etc. are all available.Su Xing looked around and said, "According to the time calculation, when Jiang Hai died, it was the pre-exam review week, and the practical exams had already been completed. There are probably some traces left here."

Sun Mingrui nodded, put the toolbox on the ground, took out the camera from it and handed it to Yan Lan, saying, "Team Yan, please."

Yan Lan took the camera and said, "Can't you recruit another person if you are in prison?"

"It's not that easy!" Sun Mingrui said while mixing the occult blood blu-ray reagent, "It costs 2000 yuan a month. With a professional camera, you can shoot dead people or live scenes. If someone is really capable, go out and take a photo of someone. The set starts at [-] yuan. But when you come to our place, it’s a bit unreasonable to go to work, and you have to be on duty when you don’t have money during the holidays. Back then, Mr. Wang could do everything from trace inspection to physics and chemistry. Let me use you, a great photographer, to take pictures of the blood stains for us."

"You talk a lot!" Yan Lan touched Sun Mingrui's leg with the instep, "I must let you have a cross talk with Fatty this year!"

Sun Mingrui stood up holding the watering can, and said, "Turn off the lights after wearing the protection!"

Su Xing nodded, turned off the lights in the room, and Sun Mingrui took the watering can and sprayed it in parallel from left to right. After a while, a large piece of blue fluorescent light appeared on the operating bed, and there were dots of blood dripping on the ground. Yan Lan was very familiar with it. He raised his camera and started taking pictures.

One advantage of the latent blood blue light reagent is that it can take clear pictures with an ordinary camera. Yan Lan clicked to take pictures while Su Xing rummaged through the cabinets in the room.

Sun Mingrui: "Su, what are you looking for?"

"The murder weapon...cough cough cough..."

Yan Lan walked to Su Xing's side, pulled the hat behind his clothes and dragged him out: "I'll get it."

"I was strangled to death by you before being choked to death by Ash." Su Xing stood aside, "Aren't you afraid that others will pull your hat like this when you wear a hoodie every day?"

"That's impossible!" Sun Mingrui answered from the side, "The last person who dared to pull Yan Dui's hat was thrown on the ground by Yan Dui."

Su Xing: "..."

Sun Mingrui gloated and said, "Su, you said that if you wore a police uniform shirt, you would be fine? Don't learn from them in criminal investigation. It's inconvenient for them to run around outside wearing police uniforms, and we don't need plain clothes to lurk."

Yan Lan took out the oxygen cylinder from the cabinet and said, "Comrade Sun Mingrui, do you also want to be thrown on the ground?"

"I was wrong Captain Yan! I will work hard!"

Yan Lan handed the oxygen bottle to Su Xing: "See if it's this one?"

Su Xing nodded: "Yes, there is still spray paint from the Second Academy on it, and there should be a base inside."

Yan Lan reached into the cabinet again to feel for a while, and then pulled out the base.Su Xing pointed to a few black spots on the base and said, "Look, Captain Yan, these pieces are exposed to iron, and the bottom of the oxygen bottle is also a little worn, so it's easy to scrape off these pieces."

"Is there any blood?" Yan Lan asked.

Su Xing took a closer look, then took out the specimen box for sampling, scraped the bottom of the bottle a few times, then sealed the specimen and put it in the evidence bag.

Yan Lan put the oxygen bottle flat on the ground and said, "I have to carry it back."

Su Xing stood up: "I'll go to another place to see, you are busy first."

Yan Lan: "Are you alone?"

Su Xing blinked: "Ah...? Is there a fourth person in this room?"

"Stop talking!" Sun Mingrui squatted beside the operating bed and said, "My goosebumps are coming back!"

"You're exaggerating!" Su Xing turned and left the room.

While taking pictures, Yan Lan said, "You and Su Xing have a pretty good relationship."

Sun Mingrui took a piece of hair from the operating bed and put it in the evidence bag, and said: "The criminal department is only about our age, and they just chat and fool around when they are free. Take a look at the few pieces of material left in the forensic room." , a boring gourd who can't kick a fart with three legs, a clean freak who can wash his hands eight hundred times a day, and a nerd who memorizes all the time, finally came a good-tempered and easy-to-get along with, and naturally got close."

Are you easy to get along with?Yan Lan sneered in her heart, how could a person who doesn't like living people be really easy to get along with?Su Xing!You can really pretend.

Sun Mingrui walked around to the other side of the operating table: "Team Yan, is this case almost over this time? I think you've relaxed a lot."

"It's almost there." Yan Lan kept the shutter in his hand, "Qiao Chen and Lin Huan are interrogating the suspect."

Sun Mingrui: "Is the time to solve the case going to break the record again? It is true that there is meat to eat with the King of Hades."

"Following the King of Hades can only bump into little ghosts." Yan Lan snorted, "You guys arrange me behind my back."

Sun Mingrui pointed to a spot on the operating bed to signal Yan Lan to take a picture, and then said, "If you know it, then it's not called behind-the-scenes choreography. By the way, Team Yan, can you give your team a vacation if you solve the case this time?"

"What?"

Sun Mingrui smirked a few times, and said, "I have asked Sister Huan several times and she always said she was busy."

"You're so brave, you dare to covet the eldest lady of our detachment?!" Yan Lan put down the camera, "I'll go to another place to see if you're all right here."

"Team Yan, please!"

Yan Lan walked out of this "operating room" and found that Su Xing was in the "dispensing room" next door. He knocked on the door and asked, "Can I come in?"

Su Xing glanced back, then nodded.

Yan Lan asked, "What did you find?"

"According to regulations, the teacher will take all the medicines used in practical exercises and exams. After the students leave, the teacher will check again and lock the door to leave after confirming that they are correct. Captain Yan, look here." Su Xing pointed out Pointing to the trash can in the house, "The yellow trash can is for storing medical waste. When I was in school, the teacher said that this trash can is here for us to be familiar with, not for us to use it."

"What do you mean?"

Su Xing explained: "I don't know much about their clinical practice classes, but I guess they are similar to ours, which is simulation training. For example, the simplest suture kit, which must be disposable in the hospital, because It is for patients. However, when students practice, they will not dismantle new ones every time. They are basically reused. So unless it is really unusable, or there are some unexpected circumstances, generally the yellow trash can is If there is nothing, there is no possibility of blood."

Yan Lan looked down and saw a small drop of blood left inside the bag of the yellow trash can.

Su Xing: "According to the regulations, all items contaminated with the patient's blood, body fluids and excrement should be thrown into the yellow trash can. As a doctor, Xu Xu must have been used to disposing of bloody medical waste, so she is very happy. It is possible that things like gauze stained with Jiang Hai's blood were thrown into this trash can, and then taken out after realizing that it was not in the hospital, and the uncoagulated blood rubbed on the bag without being noticed."

Yan Lan took out his mobile phone and took a few photos and sent them to Pang Guanglong, then typed: [Show Qiao Chen].

"But it will take time to confirm that it is Jiang Hai's blood." Su Xing said.

Yan Lan nodded: "I know, but this photo is enough for Xu Xu to tell the truth."
