After Xu Tian and Sitong went upstairs, they found that everyone had returned to the room where they stayed, and the four rooms that had been renovated had not yet installed the doors.

But Xu Tian didn't see Teacher Jin, and after walking around, Xu Tian vaguely heard Teacher Jin's snoring from a rough room not far from the staircase.

Xu Tian rarely heard Teacher Jin snoring, but Xu Tian still heard Teacher Jin's voice.

When Xu Tian walked in, Teacher Jin immediately stopped snoring and sat up immediately.

"Your business is settled?" Teacher Jin asked.

"It's been sent away, how's it going upstairs?" Xu Tian asked.

"The situation is not optimistic, it seems that Kang Yuliang doesn't know who gathered everyone here, but Kang Yuliang didn't show any fearful demeanor and movements." Teacher Jin said.

"What about the others? Is that all there is to the phone that is recorded? Xu Tian handed the phone back to Mr. Jin and said.

"I don't have a lot of time to store information on my phone, you know, but what I'm trying to say is, we should find a way to get out of here, and I have a hunch that this building won't last long, because there's no sign of wanting to finish it." Teacher Jin said.

"This is an abandoned and unfinished building, if there are workers working here in this building, there will definitely be people mentioning it when we are in Caogang Village." Xu Tian said.

"That's right, it's not just an unfinished building, but the workers we saw before who were pushed downstairs by Kang Yuliang shouldn't be the real workers working here." Teacher Jin said.

"The only thing that can be explained is that those workers should have come here to do preliminary work, and the four rooms that have been renovated should have been completed in a hurry." Xu Tian said.

"Now Dr. Lin occupies one room by himself, Li Zhitong occupies one room by himself, Hongmei and Fang Lu occupy one room, and the last room is occupied by Yanzi." Teacher Jin said.

"It's still reasonable to distribute like this, I'm afraid that something will happen to them, where are the other men?" Xu Tian asked.

"It's all on the opposite side of the stairs, because only the rooms over there are not damp, and this thing looks very suspicious, as if those dry rooms were deliberately left." Teacher Jin said.

"Are we going to get out of here tonight?" Xu Tian asked.

"Better hurry up! Hopefully the blizzard will stop tonight, and if you stay here too long, there will definitely be trouble. Teacher Jin said.

"I thought of an escape plan, now we will definitely encounter obstacles when we go out through the main gate, it is better to follow the footsteps of those workers." Xu Tian said.

"You also suspect that there is a staircase outside the building?" Teacher Jin said.

"Let's go together, do you remember the room where you saw those workers in the afternoon?" Xu Tian asked.

"Come with me!" Teacher Jin got up and said.

Teacher Jin took Xu Tian and Sitong to a room with a pile of cement, and after opening the window, a snowstorm blew in instantly.

Xu Tian did not stick out his head, but stepped on the windowsill and looked down from the inside of the house, in the dark night, Xu Tian did not see the stairs outside.

Teacher Jin made a gesture to tell Xu Tian and Sitong not to speak, and then Teacher Jin took off his coat, which was wrapped around the shovel rod in the cement pile.

Mr. Jin picked up the shovel and stretched the part of his coat out of the window.

Suddenly, some liquid fell from it, and Mr. Jin hurriedly withdrew the shovel, only to find that the coat wrapped around the shovel rod had been eroded by concentrated sulfuric acid.

"I knew it wasn't going to go that way, this happened in a hotel in Shanghai, do you remember the first hotel we stayed in when we first arrived in Shanghai? I had encountered this phenomenon at the time of the fire, so it can be seen that what happened at that time should be similar to what it is today. Xu Tian said.

"I'm most worried about a fire here, if you look at the stairs here, they lead directly downstairs, and if there is a fire upstairs and downstairs at the same time, then everyone can only stand on the stairs to avoid the fire." Teacher Jin said.

"So everybody would be stuck on the stairs, and the fires upstairs and downstairs would put everybody in between, and if that happens, everybody will be trapped in fear before the stairs collapse." Xu Tian said.

"It's a terrible thing that we can't let a fire happen, or get out of here before it happens." Teacher Jin said.

"Can you do it?" Xu Tian asked.

"What did you say?" Teacher Jin was surprised.

"You can't leave those people here, do you want to say that Sitong and I will get out of here?" Xu Tian asked.

"Shouldn't it? Behind this building may be the way down the mountain, even if the snowstorm is heavy, you will definitely be able to go down the mountain, after you go down the mountain and find the nearby pier, you will definitely see the police boat, or the helicopter that Li Zhitong is riding in is parked at the bottom of the mountain, this is no longer your stage, listen, return to Dong'an City, solve all the mysteries. Teacher Jin said.

"What do you mean...... Do you yourself stay here to deal with those people? Xu Tian asked.

"Now Lao Chen below should think the same way, you will definitely not be able to get out of the main gate, Mr. Xu, who was sent away, does not know what trap he has encountered, and can only hope that Mr. Xu will be safe." Teacher Jin said.

……

At this time, Mr. Xu, who jumped out of the window, had fallen into a deep pit, and Mr. Xu's legs and feet were not very good, and before he could go far, Mr. Xu stepped on the air and fell into a two-meter-deep pit.

Mr. Xu was about to be buried in the pit by the blizzard, and he used his last strength to write two bloody words on the wall.

……

Just around Mr. Xu, the name of the police dog sounded, and Mr. Xu did not send a distress signal, but took out the mobile phone he carried with him and took a picture of the two blood words.

Mr. Xu raised his mobile phone, he wanted the mobile phone to receive a signal, but it was useless, and now even Xu Tian, who was on the top floor, could not receive a signal.

However, Mr. Xu still sent the photo of the blood letter, and then Mr. Xu threw the phone outside with his last breath.

Mr. Xu, who was lying in the pit, could no longer move, and instead of showing fear on his face, his whole face was smiling.

After about ten minutes, the people above began to remove the snow and dirt, and Mr. Xu's body was gradually buried by the snow and mud, along with the mobile phone he threw on it.

After Mr. Xu's face was buried in the mud, the pit was permanently filled.
