Dong, Dongdong.

The dull, weird knocking sounds still sound at a fixed frequency, like a adjusted alarm clock making a sound.

The classroom door was not locked or even tied, it was just closed casually, and could be easily pushed open with a little force.

But what is creepy is that the old man in a black long gown and covered in corpse spots did not open the door, but still grew stiffly outside the door and knocked on the door, without any intention of coming in.

But although the old man did not come in, the darkness as thick as ink outside the corridor quickly came.

The entire classroom began to undergo unimaginable huge changes.

The new walls became mottled and moldy, and the wall skin continued to fall off and turned into uneven walls. Black and green mold grew on the bumpy walls, emitting a cold and humid smell. The books on the seats quickly turned yellow and then rotted. Even the cement on the ground began to weather quickly, revealing rusty steel bars, and some places even began to collapse.

It seems that in a moment, it has been decades of time and has been destroyed by time.

However, the lights in the classroom were still fighting for the darkness. The bright white lights were like candles in the wind, emitting the last dim light, as if they were about to go out at any time.

Fear appeared on the face of every student, some screamed, some called for help, and some trembled...

The only calm thing is Zhou Zheng on the podium.

He didn't move, his eyes looked around, paying attention to any movement around him.

A ghost of dangerous level can also have a ghost domain... This is not something he can deal with.

All he had to do was to try his best to find a way out and let these students live and leave here, even if it was just a small part of them.

"Zhou Zheng, look."

At this time, Fang Jing suddenly shouted, his face looked particularly ugly, and he pointed at several classmates on the desk in the classroom.

I didn't notice it before, but I saw that I had just realized that several classmates were lying on the table without moving. They opened their eyes and mouths, their faces were slapped, and their bodies emitted a rotten smell of corpses, as if they had been dead for several days.

"Dong, dun dong." The knock on the door sounded again.

At this time, the male classmate who was alive who was standing in the crowd just now suddenly trembled all over, and then fell to the ground stiffly.

"Zhao Lei, what's wrong with you?"

Someone wanted to help him up, but when he touched his body, the man screamed and retreated frantically.

Cold, stiff, like a corpse.

Zhao Lei opened his eyes and mouth as big as the classmates before him, his face was ashamed, and he was not distracted... His body gradually began to emit a rotten odor.

Dead, dead.

Moreover, more than one died, and at least six or seven students were lying on the table with a dead face.

"How could this happen? Why did this happen? Who will save us?"

A female classmate was so scared that she collapsed on the ground and cried.

"I was fine before, why did I die suddenly?" Someone said tremblingly and tremblingly.

Fang Jing, who was beside him, looked as if he was blushed: "What are you calling out? There is a ghost outside the door. No matter how we die, you will know how terrifying the ghosts that can produce ghost realm are."

The others looked at him in horror, like prey falling into a cage, full of fear and trembling.

"Zhou Zheng, haven't you come up with a solution yet? If you can't think of it, we will all die here." Fang Jing said angrily again.

His heart was trembling, because anyone in the ghost realm might die, including him.

"Talk, if you can't wait, run away by yourself, don't count on me."

Zhou Zheng also looked anxious, and he did not dare to act rashly.

"I run around in the ghost realm to die faster. Do you think I don't know anything?" Fang Jing said.

"Since you know, stand there and stay honestly. If you really want to die, you think you will die. Everyone is the same. Don't think that you feel special when you know something. Everyone is equal in front of ghosts." Zhou Zhengdao.

"Oh shit."

Fang Jing couldn't help but curse.

Yang Jian was also cold at this moment, so he forced himself to calm down because it was not a joke at this time, but it was really dead, and more than one died... If he continued, he would probably die a lot.

But when he accidentally saw the blackboard that was almost falling from the wall, he was stunned.

My eyes were stuck at the three sentences written by Zhou Zheng before, especially the last sentence: Insight into the laws of ghosts.

"Zhou Zheng dared not act rashly because he was also observing the old man outside the door and looking for his rules. Only by finding the rules can he dare to act. Think quickly, think quickly, think quickly, what rules does this old man have to find..."

His mind began to turn wildly.

Think back to everything recorded in the forum, and then think of what happened in front of you.

There must be similarities and similarities.

The netizen named Thunder and Lightning Dharma King was at home. At that time, the door of his house was closed. The old man stood outside the door and knocked on the door... and then came in, then came to the door, knocked on the door again, and then came in again.

At this moment, the ghost appeared outside the corridor and was also knocking on the door... but had not come in yet.

Why did the old man come in at the netizen's house but not here?

The same situation, the same thing, what causes the difference.

Is there not enough time?

So what is not enough time?

Is it because there is not enough time to knock on the door?

Maybe this is the key.

Fight.

Suddenly, Yang Jian plucked up the courage and shouted: "Zhou Zheng, it's a knock on the door."

"Knocking?"

Zhou Zhengyi Ning stared at the student who suddenly made a sound: "What do you think?"

Yang Jian suppressed his fear and said, "Although it's just a guess, I think this thing is killing people by knocking on the door. Maybe the old man is counting the time, maybe it's something else, but it must be related to knocking on the door. If that thing can be stopped from knocking on the door, it might be useful..."

Knock on the door and kill people.

If this is true, then this ghost would be too terrible.

"This guy's potential began to show off so quickly..."

Fang Jing looked at him with a bad look and clenched his fists: "You must not let him leave this school alive."

"I believe you once."

Zhou Zheng solemnly withdrew his gaze, and he had no choice.

If you don't act, everyone here will die.

Zhou Zheng immediately moved, and he rushed out like a violent beast, with a thin and fat monster body with explosive power that ordinary people could not achieve.

"Bang~!"

With a loud bang, the door of the classroom was knocked open by him, and at the same time, the old man outside the classroom was wearing a black long gown, with a gray face and covered with corpse spots.

The old man knocked down and fell to the ground, but no one dared to help him.

His body was in a strange position, like a stiff doll that swung his hands and feet casually, without the toughness and softness that a living person should have.

Ghosts cannot be killed.

Of course, I will not forget what Zhou Zheng wrote himself.

Even if the old man is crushed into meat paste and burned into ashes, he will still not die, and will continue to appear in an incredible way.

The only one who can deal with ghosts is ghosts.

Zhou Zheng gritted his teeth and turned around and shouted: "You see the right time and escape whenever you have the chance. I'll hold on to this thing."

After saying that, under his wide windbreaker, his bulging belly squirmed strangely.

A hand, to be precise, is the outline of a hand, stretched out under a layer of skin. The hand was gray-green and had sharp nails, as if it was about to tear open the belly and poke it out from inside.

But the belly that wrapped the hand was very resilient and was not torn. What was frightening was that the hand stretched out more than two meters.

Is this still a human hand?

In this way, this gray-green strange hand grabbed the old man on the ground.

"Sizzy~!" The sound of the light tube flashing.

In an instant, the darkness shrouded in the classroom disappeared, and bright lights appeared again. Although the walls were still mottled and the ground was about to collapse, it seemed that the disaster had been stopped.

"It's useful." Zhou Zheng breathed a sigh of relief.

But then his eyes suddenly opened wide, and his thin, almost skinny face was covered with fear.

The old man who fell to the ground slowly stood up at this moment, his dead gray eyes slightly turned, as if he was looking at Zhou Zheng.

"Impossible, I can still move if I am restricted?" Zhou Zheng's face changed drastically, and he immediately turned around and shouted. "Let's go, hurry up, leave here before the ghost realm has appeared, I will stay here to hold on to this thing."

This ghost is definitely not just a dangerous level.

He was sweating coldly in his heart.
