Ghost cannot be killed.

　　 Only ghosts can deal with ghosts.

　　 Insight into the laws of ghosts.

　　 The three sentences were clearly written on the blackboard, scribbled but clear, which shows that I was writing very hard this week.

　　 But the students studying late at night looked at each other.

　　 Is this person really here to teach? It wouldn't be a neurosis that came out of somewhere, it's just talking about something that you don't understand to fool people.

　　 Some students shook their heads underneath and expressed that they did not believe what he said.

　　 Some students also started talking quietly, and even laughed loudly.

　　 Obviously most people didn't take this Zhou Zheng's words to heart.

Only Yang Jian's face was a little dignified, because the story in the forum yesterday and the photo made him feel very uneasy, plus this person's weird words...Is it true that something is happening in this world? Don't know the changes?

After Zhou Zheng wrote three sentences, he did not continue to say anything. Instead, he looked at everyone with his haggard and bloodshot eyes: "Students, if you have any questions next or if you have any weird things happening around you, you can ask. I, I will answer for you. If there is nothing to ask, then today's safety lecture will end here."

　　 is just a society to ask questions.

　　 "Would you like to ask him about the picture of the old man."

　　 Yang Jian took out the phone with a look, opened the forum, and turned to the old man's photo again.

　　 But when he hesitated, the lights in the classroom suddenly dimmed, and the whole classroom became a little dim.

"Um?"

　　 Zhou Zheng's expression on the podium moved slightly, and he immediately became very vigilant.

Yang Jian also subconsciously raised his head and looked at it, but when he inadvertently saw a figure outside the classroom hallway through the glass window, his eyes widened, his whole body tense subconsciously, and an extreme fear surged from his heart. He came out and quickly enveloped his whole body. At this moment, his body even lost consciousness.

　　 Outside the window, an old man wearing a black gown with corpse spots on his face stood there stiffly. A pair of gray, silent eyes looked towards the classroom without a trace of expression, like a cold corpse standing upright there. 16

　　 Around the old man, it was pitch black without a trace of light. The lights in the corridor seemed to have been completely extinguished at this time, and a thick darkness eroded into the classroom like mercury.

The wall close to the old man was aging at a speed that was visible to the naked eye. The newly painted wall suddenly felt like more than ten years had passed. It began to be covered with moss. , The smell of corruption gradually permeated.

　　 "It's the old man in the forum story...impossible, why is he here?"

Yang Jian's palm was a little white due to excessive force. He firmly held the phone, and the picture of the old man was displayed on the screen of the phone. It was exactly the same as the old man outside the window, except that the old man outside the window was more terrifying than the picture... ....

　　 Then he stood up directly from his position in shock. He overturned the seat because of his excitement.

　　Because of his aggressive behavior, all the other students in the class looked at him all at once.

　　 "Yang Jian, what are you doing when you stand up, don't hurry up and sit down, don't disturb classroom discipline." The teacher behind Wang shouted when he saw this.

　　 But Yang Jian didn't hear the same at this moment, his horrified eyes stared at the old man in black shirt outside the window.

This narrative has been unlawfully taken from Royal Road. If you see it on Amazon, please report it.

　　 That old man moved...

　　 The stiff body turned in a mechanical way, gray, silent and shocked eyes, as if they were out of focus, just numbly following his head.

　　 "Da, da da~!"

　　 The clear sound of footsteps without echo rang out of the corridor and vaguely passed into the classroom.

　　 "Is he leaving?"

　　 Yang Jian broke out in a cold sweat, and looked forward to the old man being able to leave here and not to walk in.

　　 If the story in that forum is true, then once the old man walks in...the consequences are hard to imagine.

　　 But things backfired. The old man didn't leave. He just walked a few steps and finally stopped at the door of the classroom.

　　 "Yang Jian, don't you sit down yet, didn't you hear what I said? Do you dare to make trouble when giving lectures safely?" Teacher Wang became a little harsh.

　　 "Ah~!"

　　 At this time, a female classmate uttered a scream, then pointed to the book on the table and was so shocked that she couldn't speak.

　　, however, saw the books on the desk in front of her quickly turn yellow, then moldy, then rot... Finally, it became a pile of black and rotted things.

　　 "It smells so bad, Su Lei, how come there is a hump on your table." Zhang Wei pinched his nose.

　　 But the face of a male student next to him was pale, he stood up abruptly, and quickly backed away several steps.

　　 "Fang Jing, what is your ghost name?" 8

　　 Teacher Wang was very angry. What happened to all the students who are usually more self-disciplined at work tonight?

　　 On the podium, Zhou Zheng narrowed his eyes, his whole body was full of vigilance, his previous haggard color was swept away, his whole person was like a beast that came out of the cage, becoming a bit violent and ferocious, he stared at the square mirror.

　　 Fang Jing showed a calmness that was not in line with ordinary people.

　　 "It seems that you know a lot, are you also a ghost master?" Zhou Zhengdao.

　　 "Zhou Zheng, this is my business, you don't have to worry about it."

Then Fang Jing stared at Yang Jian fiercely: "It's you guy. You brought everything. I should have killed you sooner. Otherwise, it won't be like this, and in the future. You are terrible."

　　 Yang Jian looked at Fang Jing with some doubts. He didn't understand what he said, but what he cared more about was the old man in black shirt standing outside the classroom.

　　 Other students were shocked when they heard this

　　 "Fuck, Fang Jing, what you said just now almost scared me."

　　 "What the ghost master, what the future, what you said is too esoteric, I don't understand it at all, can anyone explain it for me."

　　 "Fang Jing seems to know the inside story, my thighs, please take care of me. I vaguely feel that something is wrong around me. I don't know if I am alone."

　　 "It's over, it's over, what's going on today, every one of my brains is abnormal. Is it because I can't keep up with the times, or the world is changing too fast? By the way, how come my books have become soaring."

　　 Facing the weird things that have happened, these classmates who talked didn't seem to realize that the danger had come. They were just curious and even a little excited and excited.

Sudden.

　　 dull and clear, like a knock on everyone's heart, suddenly sounded, with an almost weird tone, and passed into the classroom.

　　 At this moment, everyone feels that their soul is pinched by something, and there is a kind of depression that can't breathe under the water.

　　 "It's the knock on the door... exactly the same." Yang Jian's heart trembled.

　　 This is exactly the same as the sound from the audio file in the forum, except that it is more clearly heard on the spot.

　　 Zhou Zheng's face was extremely solemn. He picked up a special phone and pressed a button urgently, and the phone was connected immediately.

　　 "Zhou Zheng? Report the situation."

　　 A woman's voice rang on the other end of the phone.

　　 "It has been recorded."

　　 The voice on the other end of the phone was very fast: "Can you deal with it."

　　 Zhou Zhengdao: "The ghost has formed a ghost domain, and it has begun to affect where I am. I can't see the lights outside. It is estimated that the ghost domain is larger than I thought."

　　 "Ghost domain...the situation has escalated. You can't deal with it. Please retreat quickly."

"It is very dangerous to use the power of ghosts in your current state. There may be more than one ghost in your place, but two. I suggest you retreat. although your limit is fast It's here, but even if you fight for your life, maybe even one person can't be saved." The voice on the other side of the phone said immediately.

Zhou Zhengdao: "There is no time. I'm less than five meters away from the toy. I'm just outside the classroom. I might even be eyeing me. Then I will keep the communication. If it breaks, it means I'm dead. Please also transfer the suicide note to my parents for me, and that's it, I'm going to start acting."

　　 "Boom. Boom."

　　 A dull, depressive knock on the door still sounded outside, one long and two short, with a constant knocking frequency, constantly knocking on the classroom door.

　　 "Mr. Wang, someone is knocking on the door." Some students who did not know the situation shouted. 2

　　 Teacher Wang hesitated a bit, but from Zhou Zheng's appearance, it seemed that a serious problem had occurred, but couldn't help being curious. He opened the back door of the classroom and went out to see who was knocking on the door.

　　 "Don't go out." Zhou Zheng hurriedly shouted.

　　 But it was too late when he spoke. Teacher Wang had already walked out, but the strange thing was that Teacher Wang just opened the door and went out as if there was no trace in the blink of an eye.

　　 Yes, it's gone.

　　 It was pitch black outside the classroom, and the thick darkness seemed to be able to swallow any ray of light. Teacher Wang walked out and there was no more movement, not even a sound came, as if the whole person had disappeared out of thin air.

　　 And as the classroom door opened, the darkness outside quickly penetrated in like a thick black mist, constantly eroding the classroom space.
