Yan Lan walked around the room, pointed to two cabinets and asked, "Are there medicines inside?"

Su Xing: "Yes. The big cabinet is for commonly used medicines, and the small one next to it is for medicines that need to be checked by two people."

"What's the difference?" Yan Lan asked.

Su Xing explained: "Those that need to be checked by two people are relatively dangerous drugs that require strict dose control, such as opioid analgesics."

"Is the medical school still qualified to store such drugs?"

"There is only a box, and I am afraid that students will take it randomly."

Yan Lan pointed to a few small glass bottles and asked, "What about these?"

Su Xing took a look and said, "It should be penicillin. Although there is a high probability that it is a waste bottle, you should stay still. If you are allergic, I can't save you."

"I'm not allergic to penicillin." Yan Lan withdrew his hand, "You're not allergic to penicillin, are you?"

Su Xing shook his head: "No. But it's hard to say. Everyone's physical condition is different at different periods. It is possible that they were not allergic before and then suddenly became allergic. So every time you inject penicillin into a patient, you must be careful and do a skin test. .”

Yan Lan asked casually, "Is the penicillin allergy serious?"

The movement of Su Xing's hands stopped for a moment, and then he replied: "It depends on the person and the situation. If it is serious, you will die within a few minutes."

Yan Lan walked to Su Xing's side, stretched out his hand to straighten the hat behind him, and asked, "Did you be strangled just now?"

"No." Su Xing said, sorting out the evidence bag in hand, "If you want to strangle me to death, you have to use a little more force."

Yan Lan shook her head slightly: "Can you stop using your honorific title? I sound awkward."

"Alright Captain Yan." Su Xing turned around, "There's nothing else going on here."

Yan Lan raised her hand and pointed to Su Xing's cheek: "It's dirty, wipe it off."

"Ah?" Su Xing rubbed his face with the back of his hand, but the dirt on his face got bigger.Yan Lan took off the gloves and gently wiped off the ashes on Su Xing's face, Su Xing's face turned red visibly, Yan Lan smiled and said, "Okay, wipe it clean."

Su Xing took a step back and said in a low voice, "Thank you Captain Yan."

Yan Lan asked: "Don't you have a straight elevator in this building? With Xu Xu's body and strength, it is not easy for him to take Jiang Hai's body to the elevator and go downstairs."

Su Xing thought for a while and said, "There is a straight elevator, and that elevator is usually set to go down."

"Go and see in a while."

Su Xing nodded, and immediately said: "Captain Yan, Jiang Hai may not have been killed by Xu Xu."

Yan Lan looked at Su Xing with her hands in her hands, and asked, "What do you mean?"

Su Xing took out his mobile phone, found a section map of the brain, enlarged it, and handed it to Yan Lan: "Because Jiang Hai's brain bleeding was more than the other four corpses, so I went back and re-examined his brain. It was found that he had an aneurysm and it had ruptured."

Yan Lan only glanced at it, then pushed the phone back, and said, "Then you mean that Jiang Hai died of a ruptured cerebral aneurysm?"

Su Xing shook his head: "I think it's more like a double effect. He must be alive when Xu Xu hit him, but there is no isoflurane here. How did Xu Xu make Jiang Hai lie on the operating table obediently? It can't be Jiang Hai wants to die, even if Xu Xu hits him, he won't resist, right?"

Yan Lan: "Is the fatality rate of cerebral aneurysm rupture high?"

"Very high." Su Xing explained, "If the hemorrhage is not corrected in time, it is very likely that he will fall into a deep coma. If Jiang Hai had reached the fifth level of Hunt-Hess at that time, he would have died if Xu Xu hit him or not. "

Yan Lan nodded thoughtfully, and after a while Sun Mingrui also finished handling the things at hand, and the three left the medical university after handing over the finishing work to the other criminal police present.

On the way back to the police station, Sun Mingrui poked his head out from the back seat and said, "Captain Yan, is there any over-standard work meals?"

"Yes." Yan Lan turned the car to the side of the road and stopped, and said, "You go and buy it, and I will transfer the money to you when you come back."

"Ah...? Just McDonald's?" Sun Mingrui pouted.

Yan Lan turned on the double flash and said, "I'll give you 10 minutes, or I'll go back and eat a sandwich."

Sun Mingrui quickly pushed open the car door and ran out. Five minutes later, he got back into the car with a big bag in his arms. He quickly took out a hamburger from the bag and handed it to Yan Lan and Su Xing.

"Thank you, Brother Rui." Su Xing took the hamburger and opened the package, hesitating for a moment before bringing it to his mouth, but Yan Lan snatched the hamburger from his hand and replaced it with another one.

Sun Mingrui swallowed a mouthful of Coke and said, "Team Yan, why are you still grabbing food from other people's mouths!"

"I want some chicken, can't I?"

Sun Mingrui patted Su Xing on the shoulder and said, "Captain Yan doesn't know what to buy, so let him eat cheap ones."

Su Xing looked at the replaced beef burger in his hand, and said in a low voice, "Thank you, Team Yan."

Sun Mingrui handed the drink to the front: "Su, you are too honest, Team Yan just bullied you, and you still thank him?! Let me tell you, we have a cooperative relationship with the detachment, and you just scolded him. I can’t wear small shoes for you, don’t worry, if you have to resist, resist, there is our entire criminal department behind you to support you!”

"Do you believe I'll put on shoes for you right now?" Yan Lan turned around and stared at Sun Mingrui.

Sun Mingrui made a face at Yan Lan, then retreated to the back seat to eat a hamburger.

Holding the two cups of drinks in his hand, Su Xing said, "Team Yan snatched my hamburger, so I will snatch the coffee from Team Yan."

Yan Lan reached out to take the juice handed over by Su Xing, smiled at him, and drove in the direction of the Municipal Bureau.

When the group returned to the police station, Lin Huan stopped Yan Lan in the courtyard, and after everyone else had left, she said to Yan Lan, "Boss, there is no problem with the Technical Detective, the data they got is with me. The mobile phones of the deceased were all the same. None of the mobile phones of the deceased had appeared in the Tianwan community. After Xu Xu explained, she always asked the victims to go to another place and asked them to turn off their phones before taking them back to the residence, because the victim The location where the mobile phone is not online is different, and the technical investigators thought it was a signal loss or shut down automatically, and didn't think much about it, so they missed it."

Yan Lan nodded and said, "What else?"

Lin Huan lowered his voice: "Old Yu has come to inquire about our case again."

"Don't talk to him!" Yan Lan waved his hand, "This guy is idle, and he owes a beating."

Lin Huan shook his head and said, "It's different this time, I always feel that Lao Yu is a little deliberate this time."

Yan Lan smiled and said, "You're overthinking. Which of our cases doesn't he care about? He was in a hurry to show off and wanted to make up for it. If he was the one who fell down the stairs at the beginning, he would be the captain of the detachment right now, so there is no need to hang up." Under the name of an agent."

Lin Huan pouted: "Can it be your fault? Boss on the fourth floor! You were scared to death when you fell down!"

"Okay, miss, let's talk about Xu Xu."

"Deputy Qiao and Fatty are interrogating, and Jiang Hai's matter has also been explained." Lin Huan sighed, "She went back to school to help the teacher with errands, and Xu Xu saw Jiang Hai sneaking into the girls' dormitory on the 2nd day. Unexpectedly, he slipped into the school again the next day. I think Jiang Hai’s death was a bit wronged. The colleague who was in charge of contacting Jiang Hai’s wife just now told me that when Jiang Hai’s wife picked up the phone and heard it was the police station, the first sentence she asked was "Did he steal things again?" Xu Xu said that she met Jiang Hai in the second teaching building. Didn't Xiao Su say that the things in the second teaching building are very expensive? I guess Jiang Hai was not peeping when he entered the girls' dormitory building. It's about stealing."

Yan Lan nodded: "Just now Su Xing said that Jiang Hai has a cerebral aneurysm, and the information Bai Ze found also shows that Jiang Hai has been saving money. He probably wants to steal some valuables and sell them to raise money for surgery."

Lin Huan went on to say: "Xu Xu said that she met Jiang Hai on the 21st floor and thought that Jiang Hai was trying to mistreat her, so she picked up the oxygen bottle and hit Jiang Hai while Jiang Hai was squatting down, but after hitting Jiang Hai, he never got up again. .”

"Jiang Hai's cerebral aneurysm ruptured."

Lin Huan asked: "Then how did he die?"

The two had already walked into the main building at this time, and Su Xing happened to go back and forth. As soon as he saw Yan Lan, he said, "Team Yan, I just received a piece of surveillance."

"What monitoring?" Yan Lan asked.

Su Xing took out his mobile phone, clicked on the video and handed it to Yan Lan, saying, "The simulated operating room has monitoring. I just asked the teacher to help us adjust it, and it just passed it to me."

Yan Lan didn't answer, and said to Su Xing, "Transfer it to the computer to watch."

Su Xing nodded, found the nearest computer and uploaded the video.

The video recorded everything that happened in the simulated operating room on the night of July 7.

First, Jiang Hai sneaked into the simulated operating room and rummaged through the cabinets, and then Xu Xu came in, apparently hearing a noise to check.When Xu Xu turned on the light, Jiang Hai was obviously taken aback, while Xu Xu stood at the door very vigilantly, as if he was talking to Jiang Hai, Jiang Hai walked to where Xu Xu was emotionally, Xu Xu panicked and wanted to escape.

Su Xing pressed the pause button at this moment, and said, "Captain Yan, look here, Jiang Hai is not quite right here."

"Where?" Lin Huan came up and asked.

Su Xing pointed to Jiang Hai's face in the video and said, "Eyes. His eyelids droop abnormally."

Su Xing turned the video back a little bit, and said, "Pay attention to Jiang Hai's eyes and head movements at this time, and then compare the following section." Su Xing played this short video back and forth three times before Lin Huan hesitated to speak. "What happened to his neck?" he asked.

"I suspect that his aneurysm has ruptured at this time." Su Xing explained, "His movement of lowering his head was obviously blocked, but his movement of raising his head was very comfortable, which was more in line with the performance of a stiff neck, and he was walking towards Xu Xu's side. The shambling gait, profuse sweating, distressed countenance, and drooping eyelids are all clinical signs of a ruptured posterior cerebral aneurysm."

In the back of the video, Jiang Hai squatted at Xu Xu's feet, covering his head with one hand and scratching Xu Xu's clothes with the other hand. Xu Xu seemed to be greatly stimulated. Xu Xu screamed in horror.Immediately afterwards, Xu Xu picked up the oxygen cylinder standing in the corner and threw it at Jiang Hai's head as if grabbing a life-saving straw.With only one hit, Jiang Hai fell straight to the ground.Xu Xu turned around and ran out of the operating room, but came back in less than 5 minutes. She reached out to check Jiang Hai's breath and pulse, and then slumped beside her without moving.If it weren't for the time code of the video still beating, Lin Huan would almost have thought it was a picture.

After that, Xu Xu calmed down obviously. She took out a blue sheet from the cabinet and put it under Jiang Hai's body, then pulled the sheet and moved Jiang Hai to the operating bed.It is an auxiliary sheet for patients weighing more than 200 kilograms to pass through the bed. This sheet is specially made, with a smooth surface and very strong.When passing an oversized patient over the bed, fold the sheet in half and stuff it under the patient. Due to the different contact surfaces, the friction between the sheet, the gown and the bed is large, and the friction between the two layers of sheets The frictional force is small, so that the patient can quickly complete the bed by just grabbing the upper layer of cloth.

Lin Huan looked at Xu Xu's movements and said in surprise, "Why is she so energetic?"

Su Xing: "Many postoperative orthopedic patients are unable to move on their own. Doctors and nurses need to pass the patient's bed together. She will use her strength and save effort."

Next, Xu Xu in the video rummaged through the cabinet for a while, took out a scalpel, hemostat, gauze and other equipment, and tried Jiang Hai's lower body for a while, but her temptation was not successful.She inspected the corpse for a while, then raised the scalpel to Jiang Hai's face.

Lin Huan took a step back and said, "No, I won't watch it!"

Yan Lan stretched out her hand to stop the video, and asked Su Xing, "The school told us just now that there is no surveillance, where did you come from?"

Su Xing explained: "The monitoring in the corridor is turned off, but there is a set of monitoring equipment in the simulated operating room that is connected to the invigilator's room. It will be used in clinical exams at the undergraduate level. It was installed last year, and I can't use it. However, it was Cao Xuanyu who said it."

"Have you seen Cao Xuanyu again?"

"No." Su Xing shook his head, "I've been with you all the time. He saw the police and the cordon in the school and came to ask me. Don't worry, Captain Yan, I didn't disclose the case information."

At this moment, Qiao Chen came out of the interrogation room and said, "Xu Xu has explained almost everything, and Lu Huizi does have an alibi, can she be released?"

Yan Lan thought for a while, and said to Qiao Chen: "Let's let it go first. Now that Xu Xu has caught her, it's meaningless to detain Lu Huizi again. You can beat her again and let her explain everything she knows."

After a while, Lu Huizi came out of the interrogation room. She went straight to Su Xing and asked, "Can I have a word with you alone?"

"Follow me?" Su Xing looked at Lu Huizi in surprise.

Yan Lan stood aside with her hands in her hands and said, "If you have anything to say, just say it here."

Lu Huizi snorted and said, "Officer, since you let me out, it proves that I'm fine, so what I say to this forensic doctor Su is between us, isn't it too lenient for you?"

The atmosphere was a little awkward for a while, Su Xing made a rescue and said, "If it's related to the case, you'd better say it here."

Lu Huizi shook her head, leaned into Su Xing's ear and said something.Yan Lan was standing behind Su Xing at this time, and from his angle, he could just see Su Xing's gradually solidified smile.

After Lu Huizi finished speaking, she retreated to a safe distance, and said to Su Xing: "My WeChat ID is my mobile phone number. You are welcome to add me at any time."

After Lu Huizi left, Lin Huan patted Su Xing and said, "Su, are your peach blossoms about to bloom? I think Lu Huizi is the same to that Zhao Zhiqi, why don't you try with her? In fact, Lu Huizi is quite beautiful, so pretty I'm going to give you the girl... Cough, don't delay such a beautiful girl, you two are considered half of the same company, add a micro..."

"Lin Huan!" Yan Lan interrupted, "Are you free from work?"

Lin Huan raised an eyebrow with a smile: "Okay boss, I'm off to work."

Su Xing turned around and said to Yan Lan, "Team Yan, if nothing happens, I'll go back to the forensic room first."

Yan Lan stretched out her finger and pointed at the transcript on the table: "Don't you add Lu Huizi's mobile phone number?"

"No need, I don't add strangers on WeChat."

Yan Lan stretched out a finger to gently close the folder, and said to Su Xing: "If what she said has something to do with the case, you should tell me the truth."

"Does Captain Yan want to know what she told me?" Su Xing smiled perfunctorily, "There's nothing you can't say, she said she likes me and wants to chase me, it's as simple as that."

Yan Lan's hearing is very good. He actually heard Lu Huizi's words just now. It was a question without beginning and end—"I don't know where I can buy sour tricolor now?"
