"The blood stain instructions should start here." Looking at the closed door of the sports equipment room, Lin Xiko from Donghai put down the watering can containing the lumino solution in her hand and looked at Mikoto Sancheng and Chen Yu.

Standing at the door of the sports equipment room, Mikoto Misumi glanced at the closed equipment room, looked a little hesitant, and she swung for a moment and opened the door.

Like any school's sports equipment room, the sports equipment room of Cuichuan High School is also full of various sports equipment. However, some students obviously used this place as a base and sorted out a lot of activity spaces, so it was not full. There were still unfinished snacks on the table, and there were a bunch of comics and photo magazines on the ground. You can imagine what the high school students staying here were in.

After UDI's forensic trio came in, he immediately began to look for clues, but Chen Yu just watched Mikoto Misumi and Tokai Lin Xiko and Ritsuko Kube Rokuro busy, and had no intention of interfering. He even asked Hiromi of the Castle to stay outside the door.

The extraordinary perception immediately made him smell the bloody smell left in the air here and the unwillingness and resentment in the hearts of the deceased.

When he walked to the corner of the wall, he took out the rolled-up mat and spread it on the ground in the surprised eyes of Mikoto Misumi and others. The large bloodstain on the mat immediately made Lin Xiko Donghai turn his head and show an unbearable expression on his face.

This is also one of the reasons why Chen Yu didn't want Bomi from the city to come in. The scene of the murder was generally cruel, and Chen Yu didn't want his girlfriend to see this scene.

"From the area of ​​this blood stain, at least two liters of blood have flowed, it can be confirmed that it has died of excessive bleeding." Chen Yu took out a pair of surgical gloves from his body, checked the blood on the mat, and then looked at the traces on the ground. He saw some white powder on the side of the stacked comic books: "Doctor Sancheng, collect the blood stains and hairs and send them for DNA comparison. By the way, the white powder on the ground is also sent for testing. This should be the crime scene."

Looking at such a large piece of blood on the mat, Mikoto Misumi also agreed with Chen Yu's judgment, so she started working with Lin Xiko Tokai and Rokuro Hirobu, collecting various samples and preparing to send them for analysis.

However, after Mikoto Misumi collected the blood and hair on the mat, Chen Yu made a move that made her dumbfounded, and he lay directly on the mat.

"Doctor Chen, what are you doing?" Mikoto Misumi looked at Chen Yu in surprise, not understanding why he was lying on the mat. Now it has been confirmed that this is the crime scene, and the one Chen Yu is lying on is undoubtedly the location of the deceased. What is he going to do when he is lying in the location of the deceased?

"From the amount of bleeding and the position where the weapon stabbed, the deceased did not die within five to ten minutes after being stabbed, and he should have been lying on this mat, so he left such a large piece of blood on the mat." Chen Yu lay on the mat and looked left and right while explaining to Mikoto Misumi: "Since they are still alive within five to ten minutes, the deceased should have struggled for at least a while... But there are no traces of struggle left behind here."

"There are no signs of struggle?" Mikoto Misumi heard Chen Yu say this, and hurriedly looked around the mat. The piles of comics and the tables and chairs around were indeed as neat as Chen Yu said. They did not look messy, nor did they show signs of struggle: "What's going on? Did you say that the deceased just lay on the mat for more than ten minutes without moving?"

"Not only that..." Chen Yu sat up from the mat, then stood in front of the mat and looked at Mikoto Misumi: "From the wounds on the deceased and the clothes on his body in the video, he should be lying on the mat on his back, but he was stabbed behind him. If that's the case, then he should be facing the mat like I am now, so that he can explain why there is no blood in front of his clothes."

Looking at Chen Yu's back to the mat and explaining himself, Mikoto Misumi simulated the scene in her mind and immediately realized what Chen Yu was going to say: "But the wound is on the back, which means that the deceased is facing the murderer or weapon, so how did he get stabbed?"

"I'm also very interested in this question. Let's simulate it." Chen Yu showed an interesting expression on his face, looked at Kube Ryuro who was beside him, and said to him: "Ryuro, do you have a pen on your body? Use that simulated weapon, you pretend to poke me three times in the back."

"Yes, Brother Yu." Liulang nodded, took out a water-based pen from his backpack, held it in his hand and pretended it was a knife.

Chen Yu turned his back and signaled that Kube Rokuro could start.

Seeing this, Kube Rokuro walked forward and poked Chen Yu's back three times, thinking that it was a simulated murderer stabbing the deceased three times. Then Chen Yu turned around in surprise, then fell back down to the mat, but his posture was strange no matter how he looked. In the end, his body did not turn around, but just fell sideways on the mat.

"Brother Yu, is it okay?" Seeing Chen Yu lying on the mat, Rioro Hibe hurriedly reached out and pulled him up.

"It's okay." Chen Yu clapped his hands, stood up from the mat, and also looked at Rioro Kube: "Ruoro, where did you poke just now?"

"I didn't pay attention, I just stabbed it randomly." When Kube Rokuro heard Chen Yu's question, he thought for a while. It seemed that he didn't pay attention just now, so he stabbed it randomly three times.

When Chen Yu heard what Kube Ruo said, he closed his eyes and thought about it slightly, and signaled Kube Ruo to change his position with himself: "Ruolang, come here, I'll try stabbing you."

Upon hearing this, Rioro Kube nodded and exchanged positions with Chen Yu, standing in front of the mat, while Chen Yu stood behind him with a water pen.

I recalled the location of the wound on the corpse in my mind, and after comparing with Rioro Kube, Chen Yu raised his hand and stabbed him. After only two strokes, Chen Yu's movement suddenly stopped when he was about to stab the third stroke.

"What's wrong with Chen Yujun?" Seeing Chen Yu's movements suddenly stopped, Mikoto Misu known that he must have discovered something was wrong.

"No, no." Chen Yu signaled Rioro Hibe to stand and stop moving. After trying it a few times again, he felt very awkward: "Why do you need to stab here? Even if you need to stab two more, it's not right... Struggle? Then the second knife should be tilted... Why are you so far apart?"

"Chen Yujun, what's wrong?" Miko Misumi looked at Chen Yu and fell into doubt, and hurriedly asked him with concern.

Chen Yu shook his head and was still thinking, but he still answered Mikoto Misumi's question: "The location of the wound is wrong. If it is pierced three times in a row, the wound should be more concentrated according to the length of the arm and weapon."
