The sound of glass marbles sounded in this silent building, clear and weird, Yan Sheng's heart was furious, he rubbed his goosebumpy arms, and said tremblingly: "Hammer, I heard that the sound of glass marbles is because of the bouncing sound of steel bars expanding and contracting, we, we have no one upstairs, it should be like this."

Chu Wei didn't answer him, he still stood firmly, waiting for something.

"Click... Click... Click... Click..."

The sound of glass marbles rang out again, and it grew louder and louder.

"Click... Click... Click... Click...", a glass marble bounced down the stairs on the third floor, and Yan Sheng felt his legs tremble uncontrollably.

The glass marbles rolled to Chu Wei's feet.

It's weird to the extreme.

Yan Sheng couldn't stand anymore, he simply squatted down against the wall, but Chu Wei was still unmoved.

"Hammer, I'm afraid." Yan Sheng covered his mouth, and his teeth began to tremble.

Chu Wei's face was expressionless, and even a little, he wanted to laugh.

One second, two seconds, three seconds.

"Hahahahaha

A familiar figure came down from the third floor.

"Zhao Yi!" Yan Sheng obviously hadn't reacted yet, he didn't expect Zhao Yi to appear at all. The trembling of his teeth did not stop, and he quickly covered his mouth again.

Chu Wei squatted down and patted his head, his eyebrows and eyes full of teasing, "Yansheng, it's funny that you look scared." ”

Zhao Yi also squatted down, his body trembling slightly because of laughter, "Hahahahahaha, I didn't expect it, the captain of the basketball team, the rough man of 188, was scared like this by me, you said, hahahahaha, you said that this let others know what to think, hahahaha~ But Chu Wei, you rarely laugh so much." ”

Chu Wei immediately regained his expressionless face and looked at her, Zhao Yi closed his mouth very interestingly.

"Because he's stupid." He said coolly.

The three of them returned to the herbarium, closed the door, and found a comfortable place to sit and lean.

As soon as he sat down, Yan Sheng was excited and angry: "What the hell is going on? Are you kidding me?" The voice was much louder, as if it wasn't him who was shaking his teeth and legs just now.

Zhao Yi replied: "I didn't tease you, you also saw it, except for the two of you, no one remembers me at all."

"Then why are you here again, why don't you go to us?" Yansheng asked again.

"Because I can't get out, you can't see me during the day, but only at night. In other words, I'm not a human being anymore, and I don't know what state I'm in right now. ”

Yan Sheng's heart was shocked, and he gasped, and the materialist outlook that had been maintained in his heart for many years completely collapsed.

He remembered what Chu Wei said just now, "Zhao Yi, she came in, but she couldn't get out", so he asked Chu Wei: "You already knew, didn't you?"

Chu Wei said "um" and said, "I found it three days ago." ”

Three days ago, Chu Wei passed by the anatomy building on the way to the library after the last class of the afternoon, perhaps thinking of Zhao Yi, he decided to go in and have a look.

The dissection building was quiet, even the doorman uncle was not in the duty room, and from time to time there were frolicking sounds of classmates returning to bed outside the building.

Chu Wei walked slowly up to the third floor, the dry and faint smell of formalin in the air made him frown, and he walked through the corridor and down the stairs on the other side. Walking very slowly, he thought that there might really be a lot of unexplained things in this world, if you have to explore, you may have to pay some price, Zhao Yi's disappearance may not be a clue, but a punishment.

I don't know when the sunset outside the window has set, and the sky is getting darker. He went down to the first floor, and the anatomy building was going to be locked at half-past six.

Just as he walked out of the door, he seemed to hear someone behind him shouting his name, the voice was ethereal and made him think it was a hallucination, and the voice came again, it seemed to be a bit like Zhao Yi. He decided to follow the sound anyway.

A voice came from a room with a small black door, "Anyone?" He knocked on the door, but it was unlocked, and he walked in.

It's a room full of discarded mannequin teaching aids.

"Anyone?"

He thought he might be hallucinating.

"Chu Wei", Zhao Yi's voice came from behind.

"Zhao Yi!" He turned around, and Zhao Yi was standing behind him.

"It's completely dark now, or you won't be able to see me." Zhao Yi smiled helplessly.

Chu Wei was quite puzzled: "You didn't disappear?"

"I don't know, I don't know why, but it seems like I've been here since that night, like an invisible spirit during the day and an entity at night. Moreover, I found that I could not get out of this building, and I could only stay in this room during the day and walk around the building at night. ”

Chu Wei was silent for a few seconds after listening, there was more than one strange thing like this, he wasn't sure whether to talk about it or not, so he said it again and again: "After you disappeared, some strange things happened around us, except for me and Yansheng, no one remembered you, and a girl named Wan Fei appeared, replacing all the traces of your existence." ”

Zhao Yi was stunned.

"But even if others forget, Yansheng and I still remember", Chu Wei's tone was warm and full of comfort.

Zhao Yi came back to his senses and pretended not to care, "Thank you, it's okay, anyway, I have a big heart, I still like this state these days, I don't have to do my homework, haha." Laughing dryly, "By the way, it's a full moon night the day after tomorrow, that thing, I have a way." ”

So before the next full moon, Zhao Yi sprinkled phosphor and took a video with his mobile phone.

The information of the explosion scrambled into his ostrich brain, and he struggled to make sense of things.

"That is to say, after being discovered by that thing, Zhao Yi, you have become a strange state, we can't see it during the day, and we can only see it at night, and then the hammer first discovered your existence, so let you scare me?"

Zhao Yi gave him a slap on the back of the head, "I'm here to see if that thing is good or not, of course, by the way, scare you, hehehe." ”

"Okay, Zhao Yi, take out your phone and watch the video." Chu is helpless.

"Wait, I have one more question", Yan Sheng held up a hand.

"Say", Zhao Yichu said in unison.

"Zhao Yi hasn't been hungry for so long?"

"Damn, I'm retarded, sprinkle salt on the wound, what do the wandering souls eat", Zhao Yi glanced at him angrily, took out his mobile phone and watched it with Chu Wei.

The video was shot from a location where you can see the corridor and stairs on the second floor.

The video doesn't change at first, until a minute later, a white mist appears on the floor of the hallway that glows with a faint green glow, without a shape. The white mist was slowly moving towards the herbarium at the end of the hallway, leaving a trail of winding trails on the floor it passed, and when it moved to the door of the herbarium, it came to a sudden halt. It seemed that the door was blocking its continued movement, and the white mist could only flow on the door and spread all over the door. A few minutes later, the white mist on the door shrank back into a cloud and went downstairs. In the video, you can only see the traces of the white fog moving.

"Looks like this white mist is that thing." Zhao Yi said.
