The three of them were playing cards together in the bedroom, and Xue Kaimo threw out a red heart seven, already a little absent-minded.

"Have you ever heard of the multi-purpose hall in Building 1?" Li Ju, who was lying on the top bunk on the side, suddenly turned over and said to the three people playing cards under the bed.

"Where?" asked Chai Yu, looking up.

"The multipurpose hall in Building One. Li Ju repeated.

"Nope. Chai Yu said as he threw the last card in his hand.

"It's on the seventh floor. Li Ju was still reminding him senselessly.

"Isn't there only six floors in Building No. 1?" Xue Kaimo asked.

"Yes, I've seen the button in the elevator hall for the multipurpose hall on the seventh floor. Li Ju said with certainty.

"Sleep, sleep. Ke Tong, who had not spoken, waved his hand and let out a long yawn, and turned away from the table.

At night, Xue Kaimo heard Li Ju call his name while he was half asleep.

"What's wrong?" Xue Kaimo asked in a daze.

"There really is a button for the seventh-floor multi-kinetic hall in the elevator in Building 1, if you don't believe it, we can go and see it together tomorrow. Li Ju said.

"Okay, okay. Someone committed suicide by jumping off the second building today. Xue Kaimo was startled by himself in a trance, and he couldn't tell why he suddenly thought of someone jumping off the building, but fortunately, the heavy drowsiness hit him at this time, he turned over, and finally fell asleep.

The next day, almost everyone forgot about last night's conversation, and only Li Ju continued to doubt the existence of that floor. After dinner, Xue Kaimo returned to the bedroom and found Li Juzheng facing out of the window alone in a daze. The window of the dormitory faced the basketball court downstairs, and next to the basketball court was an open space behind Building 2, but Li Ju was obviously not interested in those who were playing, and his eyes had been fixed on the open space, as if he had been thinking about it for a long time.

"Have you eaten?" Xue Kaimo sat on Ke Tong's bed and asked Li Ju while lighting a cigarette.

Li Ju turned his head with an extremely strange and curious expression on his face. "Do you really not believe that Building One has seven floors?" he asked Xue Kaimo.

"Do you still remember?" Xue Kaimo asked with a little surprise.

"Let's go tonight, call Chai Yu and Ke Tong. Li Ju proposed.

Xue Kaimo hesitated for a moment and agreed to Li Ju. Faced with such an inconsequential and seemingly game-like decision, Xue Kaimo obviously didn't need to think too much, but he wouldn't have thought of what kind of cruel price he would pay for his rashness this time.

Chai Yu originally planned to go to the Internet café outside the side door of the school to surf the Internet, but there were surprisingly many people in the Internet café today, and there was no spare machine after waiting for a long time, so after receiving Xue Kaimo's call, he returned to the dormitory directly from the Internet café and waited for Ke Tong with Xue Kaimo and Li Ju.

Li Ju couldn't get through to Ke Tong's mobile phone, and the three of them waited until nearly seven o'clock when Ke Tong suddenly appeared at the door of the bedroom. Ke Tong's face was gloomy and terrifying, as if he had just seen a ghost, he didn't wait for the three people in the bedroom to speak, and preemptively said, "Let's go, I'll go with you." ”

On the way to Building One, none of the four people spoke, and no one asked how Ke Tong knew that there was someone waiting for him in the dormitory, and no one proposed to cancel the event. The four of them walked on the silent sidewalk, the white light cast by the street lamps overhead, and the cool breeze of early autumn blew on the weaker leaves of the trees beside the roadside, making a simple and dull sound.

In the elevator room of Building No. 1, the other three people really saw the button of the multi-purpose hall on the seventh floor, and Li Ju pressed the button while casting a smug look at the other three people.

"Maybe it's always there, it's just that we don't usually notice. Chai Yu said with a little disdain.

The elevator rose smoothly and soon reached the seventh floor, only after the elevator stopped, the elevator door only opened a narrow gap, and it was just enough to reach in with a hand.

The four of them looked at the darkness behind the gap, and no one spoke. Chai Yu couldn't bear it for a while, and reached out to press the button on the first floor, but the long and narrow electronic board had failed, and Chai Yu was still indifferent when he smashed it. Ke Tong grabbed Chai Yu and motioned for Li Ju and Xue Kaimo to pull the door open. Xue Kaimo and Li Ju exerted their strength left and right, the gap remained unchanged, Ke Tong and Chai Yu joined in, and the two doors were finally opened silently and slowly.

Behind the elevator door was an iron door covered in dust and cobwebs, but the handle of the door was sleek, apparently having been opened before.

"I want to go back, I have to go back. Chai Yu suddenly shouted hysterically, and Ke Tong hugged him again, covering his mouth.

Chai Yu's shouting made the atmosphere in the elevator room suddenly condense, this was a boring game, but at this time, it brought the four people into an inexplicable predicament. Xue Kaimo looked at Li Ju, and for the first time noticed a look of fear on his face.

"There's no way, it looks like we'll have to go in. Li Ju said, pressing his hand against the handle of the iron door.

"Wait. Xue Kaimo grabbed Li Ju's other arm. "If there really are people inside, what are we going to do with them?"

Ke Tong let go of Chai Yu, who had calmed down, and took out a silver-white short knife from behind him.

"I should have enough for self-defense. Ke Tong said.

"We only had a knife, but no one knew how many people were inside, and it took us four people to pull open the elevator door. Chai Yu reminded Ke Tong in a low voice. Maybe it was the short knife that lifted his spirits, and at this time Chai Yu's face had regained some blood.

"Then I don't want to be trapped here. Li Ju said as he pressed down the handle of the iron door, and pushed the iron door in front of him open, and a loud and dull echo came from not far away, and the scalps of the four people tightened at the same time.
