The three found that the small black room of the academy was actually an incinerator, and Huang Tingting, who was suspected of not being dead, was the person in charge of opening the door in the small black room.

However, the temperature in the small dark room is very high, and there is no way for normal people to survive in it.

After the inside of the small black house was quiet, Ning Qiushui circled around the small black house.

In addition to a chimney, there is only one door left in this small black room to open to the outside world, and the chimney has been emitting black smoke, and the students in that place should not be able to get out, otherwise they would not have knocked on the door just now to test whether there was anyone outside.

"The surrounding garden is full of dead trees, with traces of being cut, and when this little black house was built, was it already ready to be used to burn the students?"

"There is no other exit to the small black house, and the temperature seems to be very high in all directions, and a little further up the room is the smoke cage and the steamer, even if a partition is built on it, it is impossible to live people, the only way is to hide underground...... But it was useless to hide underground, she always had to come out and open the door, and at this temperature in the room, even if there was no smoke, it would kill someone in less than half a minute......"

Ning Qiushui stared at the iron cage in front of him, and kept deducing in his mind the situation that Huang Tingting might survive inside.

"Normal methods definitely won't work, there's no way she'll survive......"

The temperature inside the small black room was not all caused by the fire, but also partly due to the resentment of the students who were killed by the fire in the room.

Their bodies are surrounded by dead heat, and the small black room does not know how many students have died, and the room is simply a hot hell formed by a group of ghosts.

Ning Qiushui couldn't help but think of Liu Chun.

He glanced at Liu Chun, and a broken clue in his mind suddenly connected.

"Liu Chun can also come out of the small dark room alive, so if you say that, the note that Liu Chun got is likely to have special power."

"Is it ......?"

Ning Qiushui suddenly remembered a detail that was very easy to overlook.

That is, Liu Chun told him before that Huang Tingting had been called by the head teacher to talk a few times because of the decline in her academic performance.

“…… Huang Tingting also got the same note as Liu Chun? ”

The moment this thought came to Ning Qiushui's mind, the whole thing began to become interesting.

Huang Tingting, like Liu Chun, entered the small black house because of failing grades.

But unlike Liu Chun, everything Huang Tingting did was probably planned by her.

So how can Huang Tingting be sure that when she enters the small black room, the head teacher will definitely give her a life-saving note?

The biggest possibility is that the head teacher is also one of the participants of Huang Tingting's plan.

"Grass ......"

Thinking of this, Ning Qiushui couldn't help but curse a dirty word.

He found things more complicated than he thought.

As a faculty member of the college, the head teacher should be standing at the other end of the college, but it seems that things are a little different from what they saw.

However, until now, they still don't know what the head teacher, Huang Tingting, and Zheng Shaofeng want to do.

Do you want to release all these black evil spirits imprisoned in the little black room?

There was another knock at the door of the little dark room.

However, this time Ning Qiushui did not respond, he directly led the two of them in the direction of the teaching building.

After they left, the room rang for more than three minutes.

Until a certain moment, the knocking on the door suddenly stopped.

The tin door made a screeching and unpleasant grinding sound.

The rust-stained door was slowly pushed open, but the hands that appeared were white and soft, showing no signs of burns.

After the door opened, a strange dark face suddenly appeared, staring in the direction of the teaching building, with a strong resentment in its eyes......

…

Ning Qiushui and the others returned to the classroom.

Most of the students have started their lunch break or are continuing to read.

A small number of tricksters are still wandering around the school, and they seem to have found some clues, and they have not returned.

When it was time for class in the afternoon, the head teacher was unusually late, and the classroom was quite quiet, Ning Qiushui glanced at Liu Chun and asked:

"Has this homeroom teacher ever been late before?"

Liu Chun shook his head.

"Since Mr. Zuo replaced Mr. Dong to teach our class, I haven't seen him be late, and this is the first time."

Ning Qiushui frowned, and wanted to ask something more, but saw a person walk in at the door of the classroom, and when he saw this person, all the tricksters were stunned.

Because this is a person who should have died a long time ago - Zeng Shen.

On that day, he was sent to a small dark room by the head teacher (left) because of the confrontation with the teacher, and if nothing else, he had no note on him.

Zeng Shen sat back in his seat with a blank face, and then buried his head in the book.

Yang Mei and Bai Xiaoxiao were relatively close to him, and seeing that there was no head teacher outside the door, Yang Mei gestured to Bai Xiaoxiao and said to her with lips:

"Sister Xiaoxiao, what's the matter?"

Bai shook her head slightly to indicate that she didn't know, and told her to be careful.

The Zeng Shen in front of me is obviously different from before.

The previous Zeng Shen was arrogant and domineering, looking unhappy with anyone, but now he has become extremely silent, and Yang Mei is relatively close to him, and when he observes Zeng Shen's face up close, he always feels as if he is smiling.

The smile that doesn't smile is very crazy.

No one knew if he was still human, so the tricksters were amusefully silent and kept a distance from him.

After about five minutes, the head teacher returned.

But his face was not very good.

It looked much paler than before, and one hand remained in his trouser pocket.

It is a very common movement for men to put their hands in their trouser pockets, but the head teacher (left) does not have this habit.

"Are you hurt...... There was a fight, and with whom...... And the black man who escaped from the little dark room? ”

"The students in the small black room should be in the same group as Huang Tingting, and the head teacher is also part of Huang Tingting's plan, but looking at his current situation, isn't he from Huang Tingting's side, but was just used by Huang Tingting?"

Ning Qiushui looked at the head teacher on the podium seriously, touching his chin with one hand.

All the people in the class who should have come back have returned.

There was even a person back who shouldn't have come back.

According to the usual practice, the head teacher first glanced at the number of people in the class, and when his eyes touched Zeng Shen, he was obviously stunned, but it didn't take long to move away.

"Brush up on physics in the afternoon, and take the exam tomorrow morning."

"If you have any questions you don't understand, you can come up and ask me."

After the head teacher finished speaking, he sat on the podium and buried his head in his mobile phone.
