Dong Qichang heard all the plans discussed by Xu Ruixin and them, these three beautiful girls probably didn't take him a disfigured half-old man in their eyes.

They didn't know that he wasn't old, not even a few years older than them. But a beautiful person will never care about an ugly person. Besides, they don't think that what they are discussing is bad, that they are doing evil, they think that it is just a prank, a prank against someone they don't like.

Dong Qichang hates this kind of prank, especially this kind of prank made up by self-righteous beautiful girls. There is another reason, that is, he has a good impression of Niu Xinyan, a girl.

Other girls, when they saw him, would deliberately avoid him, as if they had seen the plague, only this girl, although she was also afraid of his face, never deliberately avoided her own gaze, and he could even see in her eyes the real concern and the kind of pity for the weak.

Niu Xinyan is a kind-hearted girl, she calls him Teacher Dong, and will quietly come over to help when he sorts out the equipment, and sometimes bring her boyfriend with her. They had come with real objects and had dinner with him.

He is not a good person, since the incident with Jin Ping, he doesn't think he is a good person, he feels that he is a demon, a demon hidden in a dark corner and cannot see the light, but demons also have times when they do not do evil, such as when they meet angels.

Dong Qichang looked at Xu Ruixin and the others brought Niu Xinyan to the classroom, he wanted to go directly and bring Niu Xinyan out, but then he thought about it, forget it, he felt that these three girls who were self-righteous and beautiful and had no one in their eyes should also be taught a lesson.

He followed them into the teaching building and saw the boy who was called over by Zhang Wanwan......

The night was getting deeper and deeper, but the lights in the classroom were always only one on.

Dong Qichang saw Zhang Wanwan, Xu Ruina, Xu Ruixin and Niu Xinyan walk into the classroom where Guo Hua had taken classes, and turned his gaze to the boy who was in the dark.

In the classroom, the ritual of summoning the pen fairy has begun, and the boy listened outside with his ears pricked for a while, and suddenly covered his stomach with his hands, then looked back and forth, got up, and walked in the direction of the public toilet in the teaching building.

The bathrooms in schools are the same, and there is no difference between universities and elementary and secondary schools. The boy entered the bathroom in discoloration, I don't know if he forgot it, or he was too anxious, he didn't turn on the light, but found a squatting position and walked in through the little light that came in through the only small window in the bathroom.

The boy didn't close the door, I don't know if it was because of his habit as he always was, or if he was sure that there wouldn't be any extra people in the school building late at night. Dong Qichang heard the sound of the boy farting, followed by a gurgling diarrhea. After a while, a beam of light lit up in the squatting position, which should be the boy's own mobile phone.

Dong Qichang heard the boy talking to himself, as if he was sending a WeChat voice: "Beauty, you are done, I am here for help." It's not the right thing to eat at night, and you're squatting in the bathroom at this time. If it's convenient, send some paper first. ”

After a while, Dong Qichang heard the boy say again: "Beauty, tonight, if you see no news, you will reply if you see it, you can't let me squat here all night." ”

Dong Qichang didn't speak, but took out a crumpled ball of toilet paper from his pocket, walked to the squatting position, and handed it over.

"Paper? I knew you wouldn't leave me alone. ”

The boy took the paper without looking at it, and when he finished his personal hygiene, held his mobile phone in one hand, and stood up with his pants in the other, he saw Dong Qichang standing there.

"Ghost ......"

That ghost word, the boy was covered by Dong Qichang before he could shout. His mobile phone fell to the ground, and on the screen of the mobile phone was the text message he had just sent to Zhang Wanwan.

"What about the boy, you killed him?" Ding Dang looked through the recent report records and did not receive a report of disappearance.

"No, I just threw him in the big trash can outside the bathroom."

"You mean, you didn't kill him."

"No, but I did, but then I gave up. It's not because I'm soft-hearted, it's not because I'm kind-hearted, it's that I don't want to get my hands dirty. Dong Qichang looked at his hand.

His hands were so slender and beautiful that Ding Dang could almost imagine how he used them to pinch chalk and write knowledge on the blackboard. If it weren't for that accident, he might have become the kind of handsome teacher who is very popular on the Internet now.

"You didn't kill him, so where did he go?" Ding Dang continued to ask.

"I know." Chang Tai threw out a stack of photos, all of which were screenshots of surveillance cameras, and there was a figure in the screenshot that almost looked like a black shadow. His name is Ma Shikang, and he is a normal child, and his father Ma Guomin is a teacher at this normal school, and he retired two years ago because of physical reasons. After Dong Qichang threw him in the trash and briefly fell unconscious in the trash can, he fled from the school. As for the reason for escaping, I probably thought that I had really seen a ghost.

Because his dad was a teacher in this school, he basically grew up in this school, and he knew exactly where there were cameras in the school. Although he is fleeing for his life, because he usually does a lot of bad things, he will subconsciously avoid these cameras, and only here is the east wall, where he took a little shadow of him. ”

"How did you know that he was Ma Shikang by this little shadow?"

"By analysis. I learned that Zhang Wanwan had found an off-campus person and tried to let him pretend to be a ghost to scare Niu Xinyan on the night of Zhao Bixian. But when I looked at the video materials of the school, I didn't find this so-called person from outside the school. Zhang Wanwan, Xu Ruina, and Xu Ruixin are all students of the Normal School, they eat and live in the school, and it is normal that there is no entry and exit record, but when did this person from outside the school come in? ”

"I sneak in when the students are out of school or out to eat. The university is not a secondary school, and the guards are not so strict. ”

"You're right, the access control system at the university is not as strict as that at primary and secondary schools, but the Los Angeles Normal School is different. You forget, there was a murder at this school just a while ago. Because of the case, the normal school has strengthened its management, but all students who enter and leave the school must present their student ID cards, and a facial recognition system has been installed at the door. As soon as a student is found to be not registered with the school, the facial recognition system will be activated and an alarm will be issued.

Of course, according to our years of experience in handling cases, no matter how good the system is, it is just a machine, and if it is a machine, there will be loopholes. So, I deliberately watched these videos again, and finally found this. I took this and went to the school to ask, and it was easy to ask Ma Shikang. If you investigate the relationship between him and Zhang Wanwan again, everything will be clear. ”

Chang Tai said, and took a mobile phone and put it on the table.

"In addition to the ones I just said, I found this. This was picked up in the trash can by the aunt who was in charge of cleaning at the school. The phone doesn't have a boot password, and as soon as the aunt opens it, it's this chat interface. She thought that some student with a big heart had mistakenly thrown her mobile phone into it when she was throwing out the garbage, so she handed over the mobile phone to the Academic Affairs Office and asked the teachers of the Academic Affairs Office to help find the owner of the mobile phone. ”

"This aunt is really a good person, if she changes to someone else, she will see that the mobile phone can be used, and she will not have to take it home."

"Somewhere else maybe, but not at the Teachers College." Dong Qichang said: "Because the people who work in this school are either retired and old teachers who can't stay idle at home, or the families of in-service teachers. These people usually don't have this kind of greedy idea. ”

"Let's talk about Zhang Wanwan, how did you kill her?"

"I didn't want to kill her, at least initially, I didn't have the intention of doing so. I don't know what happened in that classroom, I just know that when I threw that stinky boy in the trash and returned to the classroom, Niu Xinyan was the only one left in the classroom. She seemed frightened, and sat on the ground trembling. I walked over and called her name, but she didn't react at all, just kept talking about ghosts, ghosts.

I picked her up and told her that there were no ghosts in this world, and that even if there were, they were not as scary as people's hearts, and told her to hurry back to the dormitory. She looked at me, screamed and ran away. I regretted it a little, she was already frightened, and when she saw my face like that in the middle of the night, wouldn't it scare her soul away. Fortunately, those three people are no longer there, and I think that Niu Xinyan will recover a little and will always go back to the dormitory. I want to find those three people first and teach them a lesson. If...... If I knew that Niu Xinyan would have an accident when she returned to the dormitory, I would definitely not leave, and even if I did, I would remind the classmates who lived with her and let them watch her well. It's all my fault, it's all my fault. ”

Dong Qichang suddenly hugged his head with his hands, and kept pulling his hair with his hands.

"Dong Qichang! Dong Qichang, you look at me, it's not your fault, Niu Xinyan's matter, it's not your fault! Of course, I'm saying that it's not you who is at fault, you still have to take a little bit of responsibility. ”

"Yes, it's not my fault, it's Zhang Wanwan's fault." Dong Qichang's expression began to become terrifying, and after only a while, he turned into the appearance of a writhing woman: "Beautiful women deserve to die, especially those who are beautiful and bully." ”

"Boss, is he schizophrenic?" Ding Dang took a half step back.

"According to the information provided by the school, Dong Qichang does suffer from mental illness and has been hospitalized." Chang Tai took out a file and handed it to Ding Dang: "But this file does not indicate what kind of mental illness Dong Qichang suffers from. Now, there is still time, you go and make a phone call to contact the doctor who treated Dong Qichang in the first place. ”
