The street lights stretched Chen Ge's shadow very long. There was no one on the street. Occasionally, stray cats could be seen running past the trash can, making rustling sounds.

"Behind the bustling city, there is actually such a quiet neighborhood." Chen Ge walked through the dark buildings and along the narrow concrete road to the deepest part of the residential area.

There was a faint stench in the air. The trash cans on the roadside had not been cleaned for a long time. Various household garbage in plastic bags were piled together, and things would occasionally fall out of them.

Compared with the previous buildings, the building in front of Chen Ge looked more dilapidated. There were various stains on the walls of the first floor, and there were a lot of sundries placed at the entrance of the corridor.

"Found it." Chen Ge looked at the six-story apartment building in front of him. This was the place mentioned in the advertisement outside the residential area.

"The mission location released by the black phone is Room 303 on the third floor. Men Nan should live there." Chen Ge checked the time. It was six minutes to eight in the evening. "When Doctor Gao comes, it may be a little inconvenient. I'll go in and find out the situation first."

He didn't call Dr. Gao and went straight into the corridor.

The floors are very low, only about two meters high per floor. The guardrails are made of iron, and there is a red rope wrapped around them at regular intervals. No one knows what they are used for.

After entering, Chen Ge smelled a strange smell. It was very light, and not smelly. People who were used to living there would even slowly ignore the smell. Chen Ge was also very sensitive because it was his first time here.

"It's a bit like the smell of rotten food." Chen Ge stopped on the first floor for a while. He tried to find the source of the smell, but to no avail. The smell seemed to come from the apartment building itself, permeating into every brick of the wall.

There was no light in the corridor, so Chen Ge took out his cell phone to illuminate it.

There are four families living on the first floor, which makes it very crowded. The sound insulation of the building is not good, and the quarrels inside can be clearly heard from outside.

Chen Ge tiptoed to the third floor. He did not knock on the door of room 303 rashly, but stood outside the door and listened to the sounds inside the room first.

There were four households on the third floor. The TV volume in 301 was turned up very loud. In 302, a man was on the phone. He was not very emotional. The two sentences Chen Ge could hear him repeat the most were "Don't force me anymore" and "Do you want to kill me?"

There was no sound in rooms 303 and 304; it was extremely quiet.

After staying for two or three minutes, Chen Ge gently knocked on the door of Room 303. What's interesting is that as soon as he knocked on the door of Room 303.

The volume of the TV in 301 was immediately turned down, and the man in 302 seemed to have stopped making phone calls. The entire third floor suddenly became quiet.

Chen Ge knocked on the door for a minute, but it still didn't open. He was confused and whispered, "Men Nan? Are you home?"

After about ten seconds, the door of Room 301 opened. A very slovenly middle-aged man was leaning on the door frame. He smelled strongly of alcohol. "Hey! Who are you looking for?"

"Men Nan from Room 303. He is a student at Jiujiang Medical University."

"You've got the wrong person. I don't know who Men Nan is, but he definitely doesn't live in 303." The man scratched his face. It looked like he had been bitten by a mosquito on the left side of his face, and the skin had been scratched off.

"But my friend told me that he lives in this room." Chen Ge tried to get information from the middle-aged man. "Besides, you don't know Men Nan, so how can you be sure that he doesn't live in this room?"

"Someone died in 303. This house has never been rented out since the accident. Why do you think that is?" The middle-aged man put his hand in front of his eyes and looked at the blood on his fingertips. He scratched the wound even more. "Don't knock on the door of 303 anymore. Do you hear me? It's really unlucky."

After saying that, the middle-aged man closed the door, but Chen Ge noticed that the volume of the TV in the room was not turned up. The middle-aged man probably did not leave, but was hiding at the door and watching his every move.

Chen Ge did not knock on the door again. He had obtained a very important clue from the man: someone had died in Room 303, and since the accident, this room has never been rented out again.

The mission site mentioned by the black phone has been found. The key now is to find a way to get in and check it out before midnight.

"The black phone has never gone wrong. The cause of Men Nan's illness is probably related to this room." Chen Ge looked at his watch. It was already eight o'clock.

He called Dr. Gao, but the doctor was afraid that he couldn't find the way, so he was waiting outside the residential area and hadn't come in yet.

After explaining the situation on the phone, a few minutes later, Dr. Gao led Men Nan into the corridor.

When Chen Ge saw Men Nan again, he was shocked. This young man now looked completely different from a normal person, as if he was born with a deformity.

His head and spine were almost dislocated, and his head was drooping as if someone was pressing it down hard.

Chen Ge pointed at Men Nan and gave Dr. Gao a questioning look.

Doctor Gao immediately understood what Chen Ge meant and shook his head gently. "The situation has gotten worse. After taking the medicine, it has finally stabilized. Let's go in and talk about it."

Men Nan lowered his head and took out the key from his pocket. The light in the corridor was dim, and he tried several times but couldn't get the key into the keyhole. He was so angry that his arms were shaking, and he seemed to be sick again.

Seeing his state, Chen Ge quickly took the key and helped him open the door of room 304.

The three of them entered the house. Dr. Gao and Men Nan were already used to it and didn't think anything of it, but it was Chen Ge's first time here. As soon as he entered the room, he smelled a strange odor as if something had gone bad.

"It seems to be coming from the wall." Chen Ge looked around. The house was very clean. There was no garbage in the wastebasket. He couldn't find anything that could emit a foul smell. "Could it be that there is a body hidden in the wall?"

Chen Ge quickly rejected this guess. The wall at the deepest part of the corridor on the third floor of Ping'an Apartment was specially thickened by Wang Qi. A corpse could not be stuffed into the wall of a normal apartment.

"What are you looking for?" Doctor Gao noticed that Chen Ge behaved abnormally as soon as he entered the room, so he asked.

"Do you smell a strange smell?" Chen Ge finally stopped next to the wall between 303 and 304, where the stench was the strongest.

"Yes, a little bit. Old houses will have some strange smells." Doctor Gao helped Men Nan to the bedside, but Men Nan refused to get close to the bed. He would rather stand than sit in the bed.

Chen Ge glanced at Men Nan and asked softly, "What's wrong with him?"

"He was afraid that he would fall asleep. In his last dream, the man had strangled him by the neck. If he fell asleep again, he might never wake up again."
