“This is my first month here and my first vigil.”

"I heard from my seniors that although the salary in this hospital is high, sometimes some inexplicable things happen. At noon in the cafeteria, they would tell some ghost stories, which are quite scary."

"But in hospitals, there are always stories about deaths. I heard them when I was in nursing school. It's no big deal."

"In the evening, the other nurses went off work, leaving me and Sister Wang Ping to keep watch. Sister Wang Ping went to sleep in the second half of the night. When I went to the cafeteria to eat, I ate with Sister He. When she heard that it was my first night watch, she spoke to me in a mysterious way."

"She said that this hospital violated a taboo when it was built. This place was originally the vegetable market in ancient times, a place where people were killed. Now it is used to build a place to save people, which is in itself a conflict. Therefore, there were many problems during the construction of the hospital, and people died. In the end, human stakes were driven into the ground before it was finally completed."

"I asked what the human stakes were. Sister He laughed and said that the hospital paid a large sum of money to the families of the workers who died in accidents on the construction site and asked them not to keep the bodies, saying that they had been crushed by machinery. But in fact, the bodies were sealed in the foundation, in those pillars. Only in this way can the things here be suppressed. After saying that, she pointed to the pillar next to me."

"Although Sister He is an old senior, it seems that she had an accident a few years ago. After that, she sometimes talked nonsense. However, she is also going to transfer to a public hospital this year, so no one cares about her anymore. After she finished talking about this, she told me that I should never go to the room at the end of the corridor on the fifth floor when I am on night watch, otherwise bad things will happen."

"I thought, isn't that a storage room? Why would she go there? But I didn't ask any more questions. Sister He just picked up the bowl and left."

"When I got back to the nurses' station, Sister Wang Ping had already fallen asleep. I waited until the time was almost up, then I took the flashlight and went upstairs. They all liked to take the elevator, but I liked to walk and exercise."

"But when I was going upstairs, I always felt like someone was following me. I looked back several times but saw nothing. When I reached the fifth floor, I even heard footsteps."

"I turned around and shone the flashlight. There was no one there. But when I looked around, I found a series of footprints on the ground behind me."

"These are more like crawling marks than footprints. Yes, they are the marks left by a child crawling on the ground. It seems that the child was covered in dirt, and the crawling marks were left on the ground little by little."

"There are no children in the hospital. It's impossible. For some reason, our hospital doesn't have an obstetrics and gynecology department. We don't deliver babies, so there are definitely no children."

"I squatted down to see where the footprints came from, and I saw that they had already passed me and were crawling towards the end of the corridor."

"Most of the lights in the intensive care units on the fifth floor have been turned off. It's pitch black at the end of the corridor. I shone a flashlight around, but there's nothing there except the wall at the end."

“But the footprints just kept moving forward, step by step, towards the room at the end.”

"I feel a little guilty, but what if I really have a child?"

"After thinking about it, I decided to go and take a look. I walked past a few wards and came to a room at the end of the corridor. It was strange that there was light coming through the crack in the door, but there should be no one in this room."

"Did the cleaning lady forget to turn off the lights? I thought of this and pushed open the door, ready to turn off the lights."

"But I saw that thing in the room at the end of the corridor."

"I was startled and hurriedly closed the door. I ran away, not daring to look back, for fear that thing would catch up with me. No, I had to tell Sister Wang Ping. I saw the elevator had just reached the fifth floor, so I pressed the button to start the elevator. Before entering, I mustered up the courage to take a look at the room at the end of the corridor. I saw the door slowly open and a shadow lingered at the door."

"The elevator door finally closed. I was so scared that my legs went limp and I couldn't think of anything. As soon as the elevator door opened on the first floor, I immediately went to the nurses' station. I don't know why, but the lights in the nurses' station were turned off. Maybe Sister Wang Ping thought it was too bright. I turned on the lights and shook Sister Wang Ping hard for a long time before she woke up."

"I told her what I saw in the room at the end of the corridor on the fifth floor. She was also surprised. She put on her clothes and prepared to go with me to see it. We took the elevator upstairs. When we got to the fifth floor, the door of the room was closed. I pushed open the door with the greatest courage in my life. Then, I found that Sister Wang Ping was gone, and the things in the room were gone too. There was nothing in the room except for miscellaneous items."

"I turned around and saw that the patient in the ward was gone. It was very strange. I didn't know what happened. I could only go back to the nurses' station and call the police."

"But the phone was not working. I looked outside and it was very dark. There were no stars."

"I didn't dare go out, so I turned on the light at the nurses' station and sat here waiting for others."

"I'm so scared, is there anyone who can save me, is there anyone..."

"Can you save me?"

Lu Ban saw that the handwriting had become messy and sloppy at the end, and even the sentences were incomplete and unreadable.

He sat here, reading these words, and suddenly felt as if there was someone beside him.

It was as if the nurse, who had no idea what unexpected situation had occurred, was sitting in her chair, recording bit by bit the last scene she saw.

"Xu Xiao's record and Wang Ping's record match in some parts, but they don't match in many other places. In Wang Ping's record, Xu Xiao was already abnormal when he woke her up, but in Xu Xiao's record, he was normal the whole time. It was only when he came to the end of the corridor for the second time that something went wrong. It seems that one of the two people's records is wrong, or what they saw was real, but there was a deviation?"

"What's in that room at the end of the corridor?"

Lu Ban became more and more curious. According to Xu Xiao's records, the room at the end of the corridor was originally a storage room, but it looked like something surprising was stored in it and there were people guarding it. It seemed that all the secrets of this hospital were in that room.

All the information and clues pointed to that one room. It seemed that as long as Lu Ban pushed open that door, all his problems would be solved and all the answers were waiting for him there.

It would be more accurate to say that Lu Ban was not going to explore the house, but that the house was chasing Lu Ban, like the devil's whisper, leading him to go there.

"This memo is still missing pages, but it looks like there is no movement for the time being. Do I have to take it to the corresponding location to make the records inside emerge?"

Lu Ban immediately thought of the Sister He mentioned by Xu Xiao. According to this description, this Sister He should be He Bisong.

"The only place related to her, besides the nurses' station... is Room 502."
