Analyzing and collating clues can uncover:

Zhang Jun, a delinquent teenager, Mr. Dai confiscated his cigarettes.

Li Hao, who was in poor health so he took sick leave for a semester, and Teacher Dai physically punished him, Zama Bu and ran the corridor.

Liu Zixuan, whose parents are divorced, lives with her father, and her father has married her stepmother, and Teacher Dai forced her to do housework.

Li Qin, a child of a civil servant, a good girl, will not go against her parents' wishes, and Teacher Dai forced her to have a bullying transaction.

In addition to Zhang Jun, if the other three people take a cursory look, this Teacher Dai grasped the weaknesses of each of these three people and punished them.

Li Hao's health is poor, so corporal punishment is the most painful for him, Liu Zixuan's parents are divorced, and life at home is estimated to be difficult, and he will be forced to do housework for the teacher, Li Qin is afraid that he will be scolded by his parents for his bad grades, so he bullied the teacher.

Anyone who sees these will only grit their teeth with hatred for this Teacher Dai, how can there be such a bad teacher in this world?

"Teacher's dormitory table, Teacher Dai's room ......"

In the information sheet of teachers and staff, there is the room number of each resident teacher, and Su Chen found the room number of Teacher Dai Qiming!

"Let's go, the truth should be revealed. ”

Leaving the school archives, Su Chen took Qin Yanxi and Zhang Meng towards the teacher's dormitory building, and downstairs in the teacher's dormitory, Su Chen and the three of them saw Zhang Jun!

"Isn't this Zhang Jun?"

Zhang Meng shouted as soon as he opened his mouth, but Zhang Jun didn't seem to hear the sound, and didn't even say that he didn't see the three of them, so he ran directly into the classroom dormitory building and went straight to a certain room.

"Keep up!"

Su Chen and the three of them followed Zhang Jun's pace to the door of a teacher's dormitory building, and at this moment, Zhang Jun was holding a fruit knife in his hand that he didn't know where to find it, and he directly kicked the door and rushed in with a fierce face.

"Lao Tzu fought with you!"

Zhang Jun kicked the door open and rushed in directly with a knife, and when Su Chen and the others arrived at the door, they saw a headless man lying in the dormitory, and the head had already been cut off by Zhang Jun.

"Tell you to scare Lao Tzu, Lao Tzu is not afraid of being scared!"

Zhang Jun's state was a little crazy, Su Chen stepped forward and patted Zhang Jun on the shoulder, and at the same time, his right hand stretched out and snatched the fruit knife in Zhang Jun's hand.

"You...... Great God Su?"

Seeing Su Chen, the madness on Zhang Jun's face gradually dissipated, and when he saw the corpse lying on the ground, the whole person was dumbfounded.

"I ...... What did I do?"

"You hacked him to death. ”

Su Chen replied truthfully, ignoring Zhang Jun's mood, and asked directly: "Tell me, why did you come here and hack him to death with a knife?"

"I ...... I am here to avenge Li Hao and them. ”

Zhang Jun had a crying voice on his face, and in his narration, Su Chen and the others knew the reason why Zhang Jun was crazy.

After Su Chen and the three left, Zhang Jun and the four stayed in the dormitory according to Su Chen's explanation, but after a while, the four ghosts appeared in the dormitory, Zhang Jun watched his three classmates be killed by these ghosts, and he escaped from the dormitory under the protection of the three classmates.

Zhang Jun, who escaped from the dormitory, did not look for Su Chen and them, thinking of the tragic death of his classmates, he was so angry that he went directly to the commissary to get a fruit knife, and then came to the dormitory.

"Li Hao, all three of them are dead?"

After listening to Zhang Jun's words, Zhang Meng's face changed suddenly, Li Hao and they are also her classmates, and the relationship is not bad, otherwise she would not come back to participate in this class reunion.

"How do you know about this place?"

Su Chen's expression did not change, and he looked at Zhang Jun and asked.

"Because we also discussed it when we were in the dormitory, we felt that this teacher Dai was the most problematic, and the teachers lived in this building at that time, and when I rushed here, it happened that the lights were on in this house. ”

"So, I see, let's get out of here. ”

Su Chen's eyes narrowed slightly for a while, and the next moment he signaled everyone to leave, but as soon as the four of them walked out of the dormitory building, another figure rushed up, as if they didn't see Su Chen and the four of them, and rushed directly into the dormitory room in front of them.

"It's Li Hao, Zhang Jun, didn't you say that Zhang Hao is already dead?"

Zhang Meng opened his mouth to ask, but Zhang Jun was also at a loss, he obviously saw that Li Hao was killed by those four ghosts, how could he appear in front of him again.

"I'm going to kill you, I'm going to kill you!"

Li Hao was also holding a fruit knife in his hand, and after rushing into the room, Qin Yanxi and the others were shocked to see that the original headless male corpse in the room had disappeared, and a new figure appeared, and Li Hao directly stabbed it in with a fruit knife.

"Alright, wake him up. ”

The process of waking up Li Hao was similar to Zhang Jun, and what Li Hao said after waking up was the same as Zhang Jun, it was because he saw the three classmates dead, so he came to the so-called Teacher Dai desperately.

"What the hell is going on?"

Zhang Jun and Li Hao were completely confused, and the next moment Liu Zixuan's figure also appeared, Liu Zixuan was also holding a fruit knife in his hand, and he also rushed into the dormitory.

This time, everyone was not shocked, silently woke up Liu Zixuan, and then looked at the corridor.

More than ten seconds later, the rest of Li Qin also arrived......

Looking at Li Qin's figure rushing into the dormitory, Zhang Jun and the others didn't know what to say.

"You four, can you tell the truth now? ”

After Li Qin also stabbed the people in the room to death, Su Chen looked at Zhang Jun and the four of them and spoke lightly.

"What the truth, Great God Su, we ......"

"No need to hide it, if I'm not mistaken, you've already recovered some of your memories, remembering what happened back then. ”

Under Su Chen's gaze, Zhang Jun and the four of them all lowered their heads, and after half a ring, Li Qin was the first to speak: "Yes, I did recover my memory, after Zhang Jun and the three of them were killed by ghosts, I ran all the way, ran to the classroom, and also ran to other places, and found a lot of information, which made my memory recover." ”

"Actually, I had a good academic performance and did well in all my homework, but Mr. Dai didn't allow me to get high marks in other homework except mathematics, and if I had high scores in other homework, he wouldn't have selected outstanding students for me. ”

Li Qin's parents are civil servants, but they are just ordinary little civil servants, who have had high hopes for Li Qin since he was a child, and he has applied for various cram school interest classes, hoping to train Li Qin into a talent.

Li Qin is also very angry for her parents, she is excellent in character and learning when she is in school, and she has always been the pride of the family, and every time her parents talk about her to others, they also have a proud expression.

So what Li Qin is most afraid of is that her parents are disappointed in her, after being threatened by Teacher Dai, she can only silently endure Teacher Dai's bullying, until she just knows that she has recovered her memory, and the stimulation of the death of her classmates, this will make a move to kill Teacher Dai.

"Actually, I'm pretty much the same, Mr. Dai kept asking me to clean his house, and I was also angry but then came to kill him. Liu Zixuan also admitted.

"I'm the same, he often corporal punishment of me, and I'm revenge!"

"I don't really like to fight in school, I fight because Mr. Dai instructed me to bully other students, especially the bad ones, and then he will come forward, so that those students will be grateful to him so that he can be selected as the best teacher in the school. ”

Zhang Jun's answer made Qin Yanxi a little dumbfounded, this Teacher Dai was so bad, he was completely a well-dressed beast wearing the skin of a teacher.

"Such a teacher deserves to die. Qin Yanxi said hatefully.

"Alright, let's get out of here first. ”

Su Chen didn't comment too much, but motioned for everyone to leave here, and led everyone towards the school gate.

"Hey, the school gate is open, does that prove that we can escape?"

Qin Yanxi saw the open school gate, with a look of surprise on her face, they had also run to the school gate before, but the school gate was closed at that time, and they couldn't escape.

"In this way, that Teacher Dai is the ghost here, and they killed Teacher Dai, so the ghost domain is over. ”

Hearing Qin Yanxi's words, a strange look flashed on Su Chen's face, and the door of the campus opened, which was somewhat unexpected to him, because everything he had found so far was a little wrong with his judgment.

However, if you can leave the ghost domain, you must leave the ghost domain first.

After walking out of the school gate, the mobile phone restored the signal, Su Chen took out his mobile phone to check some news on the Internet, and when he looked up again, there was a look of clarity in his eyes.

"Let's go, let's go somewhere. ”

"Where are you going?" Qin Yanxi asked curiously.

"Going to the new Cai Gongzhuang Middle School, there are some truths that I don't think should be hidden. ”

When he finished saying this, Su Chen's gaze fell on Zhang Jun and the others, and there was a special color in his eyes.

Half an hour later, an online car-hailing car arrived, and Su Chen and his party got in the car and headed towards the new campus of Caigongzhuang.

"Great God, what are we looking for here?"

"Find the headmaster at the time, the headmaster who knows the truth about this fire. ”

Su Chen handed his mobile phone to Qin Yanxi, and a news content was displayed on the screen of the mobile phone.

"On September 20, 2015, a fire broke out in Cai Gongzhuang Middle School, and four students were trapped in the burning dormitory. ”

Qin Yanxi's pupils narrowed when he saw this news, because in this news, the teacher's name was mentioned: Dai Qiming.

Can a teacher who sacrifices his life to save his students be a bad teacher?

In addition, this teacher rescued four students, and Zhang Jun and they happened to be four people, is there such a coincidence?
