Knock, knock.

The dull, eerie knock on the door still rings at a fixed frequency, like a set alarm clock.

The door to the classroom wasn't locked, not even tethered, just closed at random, and could be easily pushed open with a little force.

But what was creepy was that the old man in a black robe covered with corpse spots did not push open the door, and still stood stiffly outside the door knocking on the door, without the slightest intention of coming in.

But although the old man did not enter, the darkness outside the corridor was as thick as ink.

The whole classroom began to change dramatically and unimaginably.

The brand new walls became mottled and moldy, the wall skin continued to fall off, and became uneven walls, and the potholed walls grew black and green mold, exuding a cold, damp smell, the books on the seats quickly turned yellow, and then rotted, and even the cement on the ground began to be quickly weathered, revealing rusty steel bars, and even began to collapse in some places.

It seems that in an instant, the kung fu here has gone through decades, and it has been destroyed by the years.

However, the lights of the classroom were still fighting against this darkness, and the white light was like a candle in the wind, emitting the last faint light, as if it was about to go out at any moment.

Fear appeared on every student's face, some screamed, some called for help, and some trembled......

The only one who was calm was Zhou Zheng on the podium.

He didn't move, his eyes looking around, watching for any movement around him.

Dangerous ghosts can also have ghost domains....... It's not something he can deal with.

All he had to do was to find a way to survive and get these students out alive, even if it was only a small part of them.

"Zhou Zheng, look. ”

At this time, Fang Jing suddenly shouted, his face was extremely ugly, and he pointed to a few classmates on the desks in the classroom.

I hadn't noticed it before, but now I saw that several students were lying motionless on the table, their eyes and mouths wide, their faces were gray, and they exuded a rancid smell of corpses, as if they had been dead for several days.

"Knock, knock. The knock on the door rang again.

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

"Li Ming, what's wrong with you?"

Someone tried to lift him up, but as soon as he touched his body, the man screamed and stepped back frantically.

Cold, stiff, like a corpse.

Li Ming's eyes and mouth widened like those previous classmates, and his face was dead and gray, without any distraction...... Gradually, the body began to emit a rotten stench.

Dead, dead.

And there was more than one dead, and at least six or seven students were lying motionless on their desks with dead faces.

"How can this be, how can this be, who will save us. ”

A female classmate sat on the ground in fright and cried.

"It was fine before, why did you die suddenly, suddenly?" said someone with a trembling voice.

Fang Jing on the side turned pale: "What do you call it, there is a ghost outside the door, it is possible for us to die, how terrifying the ghosts that can produce the ghost domain are, you will soon know." ”

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

"Zhou Zheng, haven't you figured out a way yet? If you can't figure it out, we'll all die here. Fang Jing said angrily again.

His heart trembled, too, because anyone in the ghost realm could die, including him.

"Long-winded, if you can't wait, run away by yourself, don't count on me. ”

Zhou Zheng also looked anxious, he didn't dare to act rashly.

"Running around in the ghost domain is faster, don't you know anything about me?" Fang Jing said.

"Since you know, just stand there and stay honest, if you really want to die, you think you will die, everyone is the same, don't think that knowing something makes you feel special, everyone is equal in front of the ghost. Zhou Zhengdao.

". ”

Fang Jing couldn't help but scold.

Yang Jian was also cold at the moment, and he forced himself to calm down, because it was not a joke at this time, but he was really dead, and there was more than one death...... If it continues, there is a good chance that many more people will die.

But when he accidentally saw the blackboard that was almost falling off the wall, he suddenly froze.

His eyes stayed on the three sentences written by Zhou Zheng before, especially the last sentence: insight into the laws of ghosts.

"Zhou Zheng didn't dare to act rashly because he was also observing the old man outside the door, looking for his rules, only by finding out the rules, he dared to act, think quickly, think quickly, what kind of rules can this old man find......."

His mind began to spin wildly,

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

There will be similarities, there will be similarities.

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

At this moment, the ghost appeared outside the hallway, also knocking on the door...... But it hasn't come in yet.

Why did the old man come in at that netizen's house, but he didn't come in here?

Same situation, same thing, what caused the difference.

Is there not enough time?

So what is the lack of time.

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

Maybe that's the key here.

Spelled.

Suddenly, Yang Jian mustered up the courage to shout: "Zhou Zheng, it's a knock on the door." ”

"A knock on the door?"

Zhou Zheng stared at the student who suddenly spoke up with burning eyes: "What do you say." ”

Yang Jian held back his fear and said: "Although it's just speculation, I think this thing is killing people by knocking on the door, maybe the old man is timing it, maybe it's something else, but it must be related to knocking on the door, if you can stop that thing from knocking on the door, maybe it will be useful......"

Knock on the door to kill.

If that's the case, then this ghost is terrible.

"This guy's potential is starting to show up so quickly......"

Fang Jing looked at him very unkindly, and clenched his fists tightly: "You must not let him leave this school alive." ”

"Trust you once. ”

Zhou Zheng solemnly retracted his gaze, he had no choice.

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

Immediately Zhou Zheng moved, he rushed out like a raging beast, and his strange body, which was thin and fat, had explosive power beyond ordinary people.

"Bang~!"

With a loud bang, the door of the classroom was slammed open by him, and at the same time, the old man outside the classroom who was wearing a black robe, with a dead face and corpse spots covered in corpses.

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

His body takes on a strange posture, like a stiff puppet with his hands and feet swinging at will, without the toughness and softness that a living person should have.

Ghosts can't be killed.

Of course, Zhou Zheng will not forget what he wrote.

Even if this old man is crushed into pulp and burned to ashes, he will still not die, and will continue to appear in an unbelievable way.

The only one who can deal with ghosts is ghosts.

Zhou Zhengyi gritted his teeth, turned around and shouted: "You see the opportunity, escape as soon as you have the opportunity, and I will drag this thing down." ”

After speaking, under his wide trench coat, his bulging stomach squirmed strangely a few times.

A hand, the outline of a hand, to be exact, stretched out under a layer of skin, this hand was grayish-blue, and the nails were sharp, as if to tear the belly open and peek out of it.

But the belly that wrapped that hand was very resilient and not torn, and frighteningly, the hand and foot protruded more than two meters.

Is this still a human hand?

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

"Zizi~!" the sound of the light tube flickering.

In an instant, the darkness that enveloped the classroom disappeared, and the bright lights reappeared, and although the walls were still mottled and the floor was still collapsing, it seemed that the disaster had been stopped.

"It worked. Zhou Zheng breathed a sigh of relief in his heart.

But then his eyes widened suddenly, and a sense of fear enveloped his emaciated, almost skinny face.

The old man who fell to the ground slowly stood up at this moment, his dead gray eyes turned slightly, and he seemed to look at Zhou Zheng.

"Impossible, can you still move if I am restricted?" Zhou Zheng's face changed greatly, and he immediately turned around and shouted, "Go, go quickly, while the ghost domain has not yet appeared, leave here, I will stay here and drag this thing." ”

This ghost is definitely not just a danger level.

A cold sweat broke out in his heart.
