Zhu Long pulled Zhou Tu and they looked behind them. It was pitch black around them and they could vaguely hear footsteps, but they definitely couldn't see any living people.

"Where is the person?"

"I saw them when I was picking up the kitchen knife just now. They were all standing upside down and following us, as if they were living in a world that was upside down from ours." Zhou Tu was still in shock. "Those people were staring at Zhang Ju and Wang Yicheng. Should we tell Teacher Bai?"

"Okay." Zhu Long looked behind him in confusion. Zhou Tu didn't look like he was lying.

While the two were stunned, Chen Ge and Zhang Ju had already walked to the middle of the corridor. The closer they got to the toilet, the more nervous they became.

"Teacher Bai, Zhou Tu just saw someone following us from behind. They were all standing upside down. I don't know what to say. Forget it, you should ask Zhou Tu." Zhu Long dragged Zhou Tu to Chen Ge's side.

"Just now when I bent down to pick up the kitchen knife, I saw that there were people behind us. They were upside down, floating in the air. No, they were like walking on the ceiling. Those guys should have been attracted by Zhang Ju and Wang Yicheng. I saw with my own eyes that those upside-down monsters were staring at Zhang Ju and Wang Yicheng." Zhou Tu didn't want to get close to Zhang Ju. It was an instinctive disgust.

"People standing upside down?" Chen Ge had seen those guys in the laboratory building before. "Let's go to the bathroom first to make sure the 'door' exists. If we don't find anything in the bathroom, we'll leave immediately."

This school is too weird. Even with the protection of the red clothes, Chen Ge cannot feel safe.

Quickening his pace, when Chen Ge was only a few steps away from the toilet, his neck was suddenly grabbed by a pair of hands.

Two cold, skinny arms locked around his neck. The other party was slowly exerting force, and Chen Ge's breathing gradually became difficult.

"Wang Yicheng? Are you awake?" Chen Ge turned his head and saw Wang Yicheng's head resting on his shoulder, his eyes full of black and red bloodshot. He seemed to be fighting against something in his heart.

"Don't go in, they're inside."

The voice Wang Yichen made was very different from his usual voice. It was filled with deep regret, and gave people the feeling that he was a scarred stray dog ​​who protected the body of his companion with all his strength and then allowed others to beat him.

"They? Who are they?"

"Classmates, seniors, all the people who hate you are in there, don't go over there, I have already told the teacher secretly." Wang Yicheng tried hard to force a smile, but he couldn't.

"Did you hit this kid silly? What nonsense is he talking about?" Zhu Long held a pink cell phone and quietly approached Chen Ge. The atmosphere in the teaching building was too depressing. Only by following Chen Ge could he feel a little relieved.

"Wang Yicheng, did you remember something?" Wang Yicheng's memory was triggered at the door of the toilet in the West Campus. At that time, Chen Ge was worried about being exposed and knocked him unconscious. Although he has woken up now, he seems to be a little confused mentally.

"They asked me to trick you into going in. I refused, so they beat me and made me climb the stairs with a limp. I listened to them, but they still didn't intend to let you go. Remember, no matter who tells you to go to the toilet on the top floor of the teaching building, don't go! Never go there!" Wang Yichen's voice was weak and his body seemed to be extremely weak.

"Besides you, did they find someone else to lure Lin Sisi?"

"I don't know, but I have told the teacher everything, why hasn't he come yet?" Wang Yicheng was a little anxious. The only life-saving straw in his heart was the teacher, but the teacher didn't seem to show up. Maybe the teacher also hated Lin Sisi very much.

"It's okay, I just went over to take a look."

"Don't go over there! Don't go in!" Wang Yicheng mistook Chen Ge for Lin Sisi. These were his true thoughts. It could be seen that he felt very guilty and wanted to make amends.

Having already reached the door, it was impossible for Chen Ge to give up. In addition, he now had Zhang Ju's help. This half-body red-clothed man who was constantly getting stronger was one of Chen Ge's supports.

Wang Yibo's arms were getting stronger and stronger, and veins were popping out on his arms. The boy tried desperately to stop Chen Ge from going in. He probably didn't want to see the tragedy happen again before his eyes.

The toilet on the top floor of the teaching building is at the end of the corridor. The air here is filled with a pungent smell of disinfectant. Yellow-brown stains can be seen on the wall tiles, and there are water stains and shoe prints on the ground.

Those shoe prints came from many different people.

The toilet door was locked, and Chen Ge took out a tool and forced it open.

When pushing open the wooden door of the toilet, Chen Ge took a step back and looked carefully inside the toilet.

The toilet in the East Campus looks completely different from the one in the West Campus. It is very dirty and messy, as if this place has been forgotten by the school, never cleaned, and no one has ever entered.

"Has this toilet been locked since Lin Sisi's accident?" Chen Ge turned around and asked Wang Yicheng. The child was unable to speak at this time, and his body was shaking violently as if he was sick.

Compared to the West Campus, this toilet felt more real to Chen Ge. He carried Wang Yicheng on his back and entered.

As soon as he stepped into the toilet, Wang Yicheng closed his eyes. He didn't dare to look, let alone recall.

"This room gives me a different feeling from the other rooms." Zhang Ju looked around and saw something like blood crawling all over the wall. They were like cracks all over the toilet.

The ghost faces painted on the wall have become blurred, like memories that are about to be forgotten.

Those dried blood threads crawled across all the patterns on the wall, wrapping them up, as if they didn't want to see them again.

Walking to the door of the first cubicle, Chen Ge took out Lin Sisi's mobile phone and inserted it into the gap between the cubicles. There were several figures moving on the screen.

"Who's in there?"

Chen Ge opened the compartment door with force, and the scene before him was beyond his expectations.

In the first compartment was a puppet model. He was wearing a pair of black leather shoes and was about thirty to forty years old. He looked very much like Teacher Bai whom Chen Ge had met before.

"There is a pair of shoes in the toilet of the West Campus, and there is indeed a doll in the first cubicle of the East Campus. Why is there such a difference?"

The Teacher Bai puppet in the cubicle lowered his head, clasped his hands behind his head, and stood straight, as if he had made a mistake.

Chen Ge couldn't see anything wrong with his Yin pupil. Finally, he took out Lin Sisi's phone and took a picture of the first compartment. The picture that appeared on the screen surprised him.

There was a doll of Teacher Bai standing in the cubicle, but the picture taken by the mobile phone showed a faceless boy with his hands behind his head, doing the same posture as Teacher Bai.

"Could this boy without a face be Lin Sisi? Teacher Bai has punished him in this way before? So he is using the same method to target Teacher Bai?"
