"Women's underwear?" Wen Qing didn't notice those details. It was only after she heard Chen Ge's reminder that she felt a little scared: "Is he a pervert who steals underwear?"

"Wu You must have seen his secret, so he came out to dissuade us after he knew we were in contact with Wu You." Chen Ge and Wen Qing stood in the corridor, both of them spoke in low voices so that only the other party could hear them: "What worries me most is not that the man stole the underwear, but what he said. Wu You kept the door open and waited for his parents to come home, which means he thought his family was just out, but the middle-aged man said that Wu You's parents were killed by Wu You."

"You mean, it was the middle-aged man who killed Wu You's parents?" Wen Qing followed Chen Ge, and slowly her way of thinking became very similar to Chen Ge's.

"I guess many people worked together. No one was the direct murderer, but all of them were related to the death of Wu You's parents." After meeting the three tenants, Chen Ge found that this building has its own rules. The tenants have tacitly accepted that if anyone wants to break the rules, they will probably be targeted by everyone: "When a person witnesses a murder, he does not cooperate with the police investigation and maliciously conceals it, then he is an accomplice."

"According to what you said, I feel sorry for Wu You. After we find Xiang Nuan, how about we take him away with us?" Wen Qing is a very kind woman, but kindness is the most useless thing to the natives behind the door. If they want to survive in this place for a long time, the first thing they have to abandon is the goodness in human nature.

"Let's find Xiang Nuan first."

After walking up the stairs to the second floor, Chen Ge and Wen Qing stopped.

An old lady was standing on the eerie second-floor corridor, holding a stained porcelain bowl in her hand, which contained some coins and some leftover food.

The old woman was standing outside a door and was turning the doorknob hard, but no matter how hard she tried, she couldn't open the door.

When Chen Ge passed by, the old lady saw him, turned around and walked towards him.

The stained hands were waving in front of Chen Ge. She was holding the bowl and making a gurgling sound from her mouth, which sounded terrifying.

"Granny Li?" Wen Qing recognized the old lady in front of her. She was very surprised when she saw the old lady's appearance.

"Do you know her? From your neighborhood?"

"She used to be, but then her son said she was lost and he hasn't seen her for a few years." Wen Qing's eyes were full of surprise: "The old lady lived a very refined life. Her hair was combed neatly, and there was not even a wrinkle on her clothes. She often took care of the flowers and plants in the garden by herself."

"Could it be that her son didn't want to take care of her and abandoned her?"

"That's his mother, not an item. How can you just throw it away?"

"Don't overestimate human nature. I was watching the news the other day and saw a man burying his paralyzed mother alive. Even the media wouldn't dare to write about that."

Chen Ge and Wen Qing stood there. The old lady seemed to have been strongly stimulated by something. She was crazy and unable to communicate. She just kept extending the bowl to Chen Ge.

"Are you hungry?" Chen Ge didn't mind the old man's stained coat. He walked up to the old man and said, "Do you want me to take you home?"

Through Wen Qing's brief description, Chen Ge felt that this crazy old lady was a "good person" and a potential partner worth winning over.

The old lady seemed unable to speak a complete sentence. She anxiously stretched the bowl in front of Chen Ge, making strange noises in her throat.

Chen Ge took out a piece of change from his pocket and put it into the old woman's bowl, but the old woman still held the bowl stubbornly, gesturing with her hands. What she wanted was not money, but something else.

The old man made a lot of noise. After a stalemate of more than ten seconds, the door of Room 206 on the second floor near the stairs was opened.

"You again." The person who opened the door was a young man wearing headphones and looking pale, as if he hadn't seen the sun for a long time. "I just kicked you out, why are you back again?"

He looked at the dirty old man with disgust, walked out of the house, and pulled Chen Ge and the old man apart: "Don't get entangled with this old woman, otherwise she will always follow you, like a ghost, and be disgusting."

The young man in Room 206 was the most normal person Chen Ge had seen behind the door so far. Whether in his tone of voice or his physical appearance, he was the same as the ordinary people outside the door.

"Xiao Sun?" Wen Qing recognized the young man, but the young man did not recognize her.

"Who are you? Forget it, I'm not interested in knowing. Just be quiet, I'm recording a song in there." The young man said and closed the door.

"Is that young man a relative of the old lady?" Chen Ge asked softly.

"No, Granny Li lives in 205. Her son looks very fierce and doesn't look like Granny Li at all."

"Who is Xiao Sun? He gives me a different feeling from other tenants." Chen Ge looked at Room 206. As he came into contact with more and more tenants, he became more and more confused. This was the world behind Xiang Nuan's door. What kind of relationship existed between these people and Xiang Nuan?

"Xiao Sun is a college student who likes singing. He once rented a house in No. 206, Jinhua Community for a period of time. He paid the rent for half a year in one lump sum, but left after the second month without asking for the deposit. He also left many things unpacked. The landlord complained to me for a long time."

"What's your impression of Xiao Sun?"

"He rarely leaves his room, doesn't go to class, doesn't talk much, and occasionally goes to the supermarket to buy a lot of daily necessities and food. In my impression, he is just an ordinary homebody."

"A very ordinary otaku disappeared mysteriously after living in your community for two months." When Chen Ge opened the door just now, he used his Yin pupil to glance inside Room 206. He found that there were several cracks on the wall of Room 206, the wall paint was severely peeling, and the interior decoration of Room 206 was extremely poor.

"Why did he disappear so mysteriously? Maybe he just had something urgent to do and didn't have time to inform the landlord. Oh, by the way, I heard from the landlord that the room Xiao Sun rented was very messy, with garbage piled up like a mountain and the furniture was damaged. Maybe he was worried about having to compensate the landlord, so he ran away secretly."

"A sheep lives with a pack of wolves. What do you think will happen to the sheep?"

"What do you want to say?"

"If he hadn't turned into a wolf, he would have been eaten by the wolf. When everyone is an accomplice, if you don't want to be an accomplice, then you can only be a victim."

Granny Li also heard what Chen Ge said. What's interesting is that Granny Li, who was originally very emotional, gradually became more and more emotional. She seemed to understand what Chen Ge said.

Chen Ge had expected Granny Li's reaction. He had just discussed Xiao Sun in front of Granny Li just to test her.

It is very difficult to survive in the world behind the door, and every "person" must have his own reason not to be killed.

Wu You is a liar, Granny Li is crazy, and Xiao Sun looks the most normal, so his future situation will be the most dangerous. Of course, if he has already "compromised", that would be another matter.

Granny Li was speechless as she held the porcelain bowl with trembling hands. She stopped her strange movements and just followed Chen Ge, unwilling to leave.

Everything was just as Xiao Sun had said just now. Granny Li was like a "life-seeking ghost" and refused to leave no matter what.

"Xiao Sun should have experienced something like this before. If I'm not mistaken, Granny Li is actually reminding him, or she wants to ask Xiao Sun for help in this way."

Chen Ge was very curious about why Granny Li couldn't speak. According to Wen Qing's memory, the old lady shouldn't have any problems with her throat.

"Can't say it? Or dare not say it?"

Without staying on the second floor, Chen Ge, Wen Qing and Granny Li followed them and went to the first floor together.

"Uncle Huang lives in Room 104. Only three rooms on the first floor are occupied. The other three rooms have been converted into utility rooms and warehouses." Wen Qing also felt that Uncle Huang could be trusted, so she was even more anxious than Chen Ge. She ran directly to the door of Room 104 and knocked on it.

While Wen Qing was knocking on the door, Chen Ge was looking at the corridor on the first floor.

Unlike the world behind Ying Tong's door, the interior space of this building is not an infinite loop. The entrance to the corridor is right in front of you, but there is a rusty iron door at the exit, and the door is locked. You must have a key to go out.

"The exit door is locked. If Xiang Nuan doesn't have the key, he should still be in the building. But what if Xiang Nuan has the key?"

It has been a while since Chen Ge entered the door, but he still has no clue. He cannot see Xiang Nuan's despair. All he sees is the despair of others. Xiang Nuan herself is more like a bystander.

"The corridor on the first floor has the most bloodstains. The black blood has seeped into the floor tiles, and blood-like lines have appeared on the wall. This floor is likely to be more dangerous than the floors above."

While Chen Ge was thinking, the door of room 104 was opened, and then Chen Ge heard Wen Qing's exclamation.

"What's wrong?"

Chen Ge looked back and was also startled.

The iron door of Room 104 was opened, and an old man with a hunched back stood behind the door. He was very short and seemed to have something pressing on his back.

If it were just this, Chen Ge wouldn't even frown. The most terrifying thing was the old man's face.

That wrinkled face was covered with teeth marks, and all the bite marks were of different depths and not exactly the same, as if they were made by different people.

"Uncle Huang?" Chen Ge asked uncertainly. He forced himself to act normal.

"My surname is Huang. Do you have something to talk to me about?" The old man walked out of the room with a hunched back. An indescribable stench emanated from his room.

"Uncle Huang, I'm Wen Qing..." Wen Qing frowned and said stiffly.

"Wen Qing?"

"Don't you remember me? I often brought you meals. Once you were sick, I took you to the hospital and took care of you every day." Wen Qing had never told Chen Ge about these things before.

"I'm sorry, I'm old and I really can't remember some things. Are you a resident here too?" The old man looked confused. He seemed very weak and coughed every few words.

"Of course, I live in ..."

"Uncle Huang, we want to ask you something." Chen Ge decisively stopped Wen Qing and did not let her continue speaking.

In fact, he had already discovered something was wrong. No one in the world behind the door seemed to know Wen Qing. The person who was most important to Xiang Nuan had no known name in the world behind the door.

The flyers on the wall that insulted Wen Qing did not have Wen Qing's face and had become headless photos.

Just now, Xiao Sun had no impression of Wen Qing, and now Grandpa Huang also has no memory of Wen Qing at all. This is definitely not a coincidence.

The door was pushed open by Xiang Nuan. Chen Ge felt that Xiang Nuan was protecting Wen Qing specifically. He didn't want Wen Qing to have any connection with the world behind the door.

Even if she fell into the abyss, Wen Qing was still the same Wen Qing in the world.

"It's a good idea, but he probably didn't expect that Wen Qing would follow him into the world behind the door." Chen Ge didn't say this out loud. He just thought about it in his mind. The focus now is to figure out whether Mr. Huang is an enemy or a friend.

"What do you want to know?" The old man was in poor health. He held the door with his hands and his back was even more hunched.

"Uncle, has anyone ever left through this door at the entrance of the corridor?"

"Probably not. It's been quite chaotic outside recently, so the landlord put a lock on the door. The key is with the landlord. If you want to go out, you must find the landlord." Grandpa Huang revealed a lot of information in just one sentence.

It's quite messy outside, which means they know the situation of other buildings to some extent. This community is a whole and there are connections between them.

The lock was added by the landlord. If Chen Ge and his friends wanted to go out, they had to find the key from the landlord first.

Finally, Chen Ge understood one thing from the old man's words. At least in this building, the landlord was a very important person. He had completely ignored this person before.

Before entering this door, he didn't have time to contact the landlord because of time pressure. Now he can only rely on Wen Qing's understanding of the landlord to figure out the landlord's situation.

"Is there anything else? If not, I'll go back. I'm old, and my legs hurt after standing for a while." After saying this, Grandpa Huang was about to close the door, but he only closed halfway when the security door was caught by Chen Ge.

"Uncle, can we sit in your room for a while?"

The stench in Grandpa Huang's room was extremely strong, the heaviest of all the rooms. Chen Ge felt that there must be some secret hidden in this room, so even if Grandpa Huang disagreed, he would try every possible way to go in and check.

"As you wish."

Grandpa Huang did not reject Chen Ge's somewhat unreasonable request. He seemed to be really tired. After saying this, he leaned against the wall and sat back on the sofa in the house.

When Wen Qing saw the sofa, her scalp tingled again. The back of the sofa was covered with tiny things that looked like blood vessels.

Uncle Huang curled up on the sofa, and the expression on his face finally relaxed.

Wen Qing wanted to remind Chen Ge, but Chen Ge had already walked in. He seemed to be unable to see those scary and strange things at all, as if he had returned to his own home, and sat down casually opposite Grandpa Huang.
