There is a detail in the story told by Zhang Ju. On the senior's birthday, a girl confessed her love to him. After he rejected her politely, he and his roommates celebrated his birthday by drinking and singing.

When Chen Ge first met Zhang Ju, the other party said that his face was burned by a fire while he was singing in a KTV.

Originally, Chen Ge did not connect these two things together, but now Zhang Ju's behavior was too abnormal, which gave Chen Ge an idea.

All club members' memories of summer vacation are vague, which means that their memories of summer vacation have been altered by someone and that memory is unreliable.

Zhang Ju was very familiar with the school and knew the story between the senior and the girl who confessed her love to him. The most important thing was that his face was burned by the fire while he was singing, which was consistent with what the senior did that night.

After connecting all of this together, Chen Ge had several guesses. The first one was that Zhang Ju was the senior who killed the girl. He was a complete scumbag and a pervert who was good at disguising himself.

Second, Zhang Ju was a senior, and the girl was killed while waiting for him, and he happened to witness the process. However, due to fear, panic, or other reasons, he did not stand up to stop the murderer, so he felt very guilty.

Third, Zhang Ju was a passerby or a friend of the senior. He accidentally witnessed the senior killing the girl, but for some reason, he did not stand up to testify against the senior.

In just a few seconds, Chen Ge had thought of several possibilities: "Desperate, vicious, and some people who emit negative emotions were all transported to the East Campus. Zhang Ju should not be the murderer."

The murderer not only killed the girl, but also did so in a very cruel way. It is unlikely that such a person will show any remorse.

"Teacher, can I take this frame away?"

"Does this frame have any special meaning to you?" Chen Ge narrowed his eyes and asked tentatively: "After all, this is something from the anatomy lab. If you take it away directly, I need to tell the teacher in charge here."

"I don't know why. This was the first time I saw this mirror, but after entering the autopsy room, I went straight to the curtain, as if I knew there was a mirror hidden behind the curtain." Zhang Ju's face was scary, but his expression was somewhat cute. In Chen Ge's opinion, it was almost impossible for such a child to be the murderer.

He has always been good at judging people, especially after having come into contact with so many perverted murderers.

"Okay, but you have to promise me not to break or lose this frame."

"Yeah!" Zhang Ju nodded heavily. In front of Chen Ge, he was just a kid who had just taken the college entrance examination.

Holding the frame tightly with both hands, Zhang Ju's confused eyes revealed a hint of guilt, which was revealed inadvertently without him even realizing it.

“Bang!”

Chen Ge was talking to Zhang Ju when a loud noise suddenly came from the front of the autopsy room.

He turned around and saw Zhu Long turning over the entire metal test bench.

He was not a medical student and did not know that there was an adjustable spring next to the test bench. Instead, he used violence to force open the test bench.

"What are you doing? You have to pay compensation for damaging school property." Chen Ge walked towards Zhu Long, who was bending over and standing next to the test bench, and put his head into the test bench.

"Zhu Long?"

The bad-looking boy didn't reply, his shoulders were shaking slightly.

"Are you okay?" Chen Ge grabbed Zhu Long's shoulder, and the other party slowly turned his head.

Zhu Long's facial muscles twitched, and there were two tear marks on his face. His eyes were full of panic, as if he had seen something extremely terrifying.

Chen Ge gently pressed Zhu Long's shoulder and took a look inside the test bench. The back of the test bench was engraved with the word "Zhu Long" with a sharp weapon.

"Why does my name appear on the back of the dissecting table in school?" Zhu Long's voice was trembling, and his body was shaking even more violently.

"I want to know why too." Chen Ge bent down and touched the names with his fingers: "The person who carved the names must hate you so much to use such force."

"I don't know anyone in this school! Why did they carve my name in the anatomy room!" Zhu Long kicked the test bench hard, making a loud noise again.

Chen Ge ignored him and took out Lin Sisi's phone to take a photo.

His finger slid across the names one by one, and then stopped at the lower left corner of the test bench. In addition to the name, there was a sentence written there - I came to find you, and you said that as long as we can both become students of this school, you will be with me forever!

"Is Zhu Long's story true?" Looking at the words on the back of the test bench, Chen Ge shook his head again: "Zhu Long doesn't seem like the kind of person who is good at calculating. There are many steps to donate the body to the school after death. The most important thing is that the body is a suicide, and the school rarely accepts it."

"Don't panic. Check if there is an attendance list and seating chart in the autopsy room. It will take a lot of time to carve so many names. The perpetrator should sit in this position every time." Chen Ge quickly calmed down. He and Zhang Ju looked around, but Zhu Long just stood there stupidly.

After a long while, he wiped the tears from his face and said in a very slow tone: "Don't look for it, these words give me a very familiar feeling, they should be... carved by me."

"You carved it?" Zhang Ju was still immersed in his own affairs at first, but he woke up immediately after hearing Zhu Long's words. The more he thought about it, the more scared he became: "Zhu Long, what do you mean? Now is not the time to joke!"

"I don't remember when I carved it, but I know I carved these words!" Zhu Long hit his head hard. He used a lot of force.

"It doesn't matter if you can't remember. Do you remember what I said before? All the students I choose to join the club are not ordinary people. I will help you remember." Chen Ge took out the scalpel he used to pry open the door from his backpack: "Don't be affected by those words. Carve your name on the spot according to your feelings."

Zhu Long took the scalpel and carved his name on the back of the test bench with trembling hands.

The sound of metal friction seemed even more harsh in the silent night. Zhu Long stopped after carving just the red characters. The red characters he had just carved were exactly the same as all the red characters on the back of the test bench.

The words on the back of this metal test bench were indeed written by him!

"bite!"

The scalpel fell to the ground, and Zhu Long suddenly covered his head. He knocked over the test bench with force, and veins popped up on his face.

"Hold him down!"

Chen Ge and Zhang Ju grabbed Zhu Long's hands and legs. Zhu Long was still struggling desperately. All the data and records in the No. 1 test bench fell to the ground.

"Teacher Bai, what's wrong with him?"

"It's too noisy, let's get out of here first!" Chen Ge hugged Zhu Long, and when he was about to leave, he found an old-fashioned mobile phone with a pink shell in the pile of information.

Chen Ge used his free hand to pick up the phone and stuffed it into his backpack. In the blink of an eye, Zhu Long broke free.

He banged his head against the test bench, screaming, "Let me go! Let me go!"
