Li Ju turned on the searchlight on his mobile phone, and the four of them found that outside the iron gate was a narrow corridor, the left side of the corridor was blocked by a stone wall, and at the end of the right side were two rotten wooden doors.

"This is the multipurpose hall, and maybe we can find another exit in it. Li Ju shone a searchlight on a wooden board with the words "multipurpose hall" written on it above the wooden door, and said to the other three people.

"Let's go, go inside. Chai Yu said. His tone was surprisingly calm, as if he had forgotten the struggle and shouting he had just been in the elevator.

Ke Tong walked over, clenching the short knife in one hand and pushing the wooden door tentatively with the other. The two doors opened silently, and the dust moved slowly in the glow of the searchlight, making people feel suffocated.

The four of them stood at the door, Xue Kaimo, Ke Tong and Chai Yu also took out their mobile phones, and four strong white lights entered a spacious and empty classroom, all that could be seen were scattered tables, chairs and lecterns, as well as a curtain behind the lectern and four tall windows.

"Maybe we're overthinking. Li Ju was the first to walk into the classroom as he spoke, followed closely by the other three.

Xue Kaimo reached out and pressed the light switches next to the wooden door, and found that they were all broken, just like the switches in the hallway.

"Let's check separately, Li Ju and I will go to the back, and you and Chai Yu will go to the front. Xue Kaimo said to Ke Tong.

"Good. After Ke Tong finished speaking, he and Chai Yu walked to the front of the classroom, and Xue Kaimo and Li Ju walked to the last row of the classroom.

The classroom seemed surprisingly large, even with hundreds of desks and chairs, it still seemed empty. Xue Kaimo and Li Ju started from the last check, and the two beams slowly moved forward, and finally converged at the seats in the middle of each row. Ke Tong and Chai Yu also used the same method, but from time to time there was the sound of desks and chairs colliding from the front of the classroom, which made everyone's hearts tremble from time to time.

The last four returned to the door, each with a fine bead of sweat on their heads.

"Eh, a false alarm, maybe those people came yesterday and are a bunch of boring guys. Xue Kaimo let out a sigh.

"There's nothing special here, except for the tables and chairs. Chai Yu said and took out a cigarette and handed one to Xue Kaimo and Ke Tong.

"Let's take a closer look, there must be other exits, or how the people who came here yesterday got back. Li Ju dodged the smoke and walked to the front of the classroom.

"Come and see. Li Ju shouted to the three people who were smoking. The atmosphere that had just been eased suddenly condensed again, and the three of them threw their cigarette butts and ran towards Li Ju.

Li Ju stood next to a desk in the first row, on which was an old diary, the cover of which was covered with dust, and it was no longer possible to see its original face. But on the thin layer of ash, there was a vague outline of the handprint, like a girl's hand, slender and thin.

Perhaps sensing the strangeness of this diary at the same time, none of the four of them reached out to touch it, they stood quietly around the diary, until Xue Kaimo noticed that the huge curtain behind the podium was a little strange.

The curtain hanging behind the podium may have been for the projector, but unlike the rest of the room, it was clean and white, as if it had just been freshly scrubbed.

"Look here. Xue Kaimo said, using the searchlight of his mobile phone to shine at the corner of the curtain.

In a circle of white light, a figure with a clearer outline appeared, and the figure gradually stretched out and began to run towards the edge of the other end of the curtain. The other three rays of light joined in, and more and more shadows began to appear on the curtain, and from their forms it appeared that there were men and women, all running in the same direction. As they ran, people kept falling, others stepping on their bodies and frantically rushing to the more crowded front. Eventually, all the figures piled up on the edge of the curtain, as if they were being blocked by something. Li Ju shone the searchlight out of the curtain, only to find that next to the curtain was a window that had been sealed with cement, and he looked at the other three windows, and found that they were also sealed, only a dark square appeared. The figure on the curtain begins to despair, and one of the figures reaches out and clasps the upper and lower rows of teeth in each other, and then tears them so hard that a bloody jaw (a spot on the curtain) falls to the ground. A figure picks at other people's eyeballs, picks them out and puts them into his mouth one by one, and finally he jams his neck and flips wildly on the ground. A man took out a lighter and set his hair on fire. In short, the scene on the curtain became more and more bloody and cruel, even if it was just a group of black and white shadows, enough to make the four people in front of the curtain stunned.

Suddenly, the lights in the multipurpose hall turned on at the same time, illuminating the empty classroom in a miserable white, and the figures on the curtain disappeared in an instant, leaving only a dazzling reflection.

"Look!" Li Ju suddenly shouted.

The three of them followed Li Ju's guidance and found that a slender and thin girl's hand stretched out from under the desk where the diary was placed, and quickly took the diary. After the diary was taken away, the lights in the classroom went out again, and the four of them ran to the door of the classroom together before they had time to discuss with each other.
