"Walk close to the wall and stay away from the railing. Be careful not to fall." Captain Yan found Room 104 and entered.

The biggest difference between this room and other houses is that it is filled with all kinds of shabby furniture and there are many children's graffiti on the mottled walls.

"It feels like a family of three has lived here." Chen Ge followed behind Captain Yan. He had Yin pupils and didn't need a flashlight. He walked around the house on his own: "What is this?"

There were many shriveled apples thrown next to the wooden table with a missing leg, and bitten apples could be seen under the table.

"The people who live here must love eating apples." Chen Ge picked up an apple with a piece of paper under it and took a look. It was rotten and had mold growing on the surface. Seeing this apple, he suddenly remembered the apples he had seen in the underground morgue. "For corpses, apples seem to have a special meaning. I can ask those doctors when I have time."

"Look here!" Tian Lei, who had always had a weak presence, suddenly spoke. He shone the flashlight on the left wall of the living room.

There was a slightly strange painting on the cracked wall. Two adults and a girl were talking together, and not far away there was a little boy drawing.

"These two adults should be the child's parents. The girl is their daughter, and the one drawing on the wall is a boy." Li Zheng tried to analyze: "It turns out to be a family of four."

"When we asked Jia Ming before, didn't he say that they didn't have children because of Huang Ling's health?" Tian Lei raised his eyebrows slightly: "Could it be that this guy has a mistress? Or did he lie to us?"

"He must have lied to us, but he probably didn't deceive us about the child." Captain Yan walked out of the kitchen: "The house hasn't been fully built yet. It's not Jia Ming and Huang Ling who live here, and the child who's painting may not be related to them."

"Are they homeless children?" Li Zheng stood by the window and looked outside. "But why do they have to live in this room? There is no elevator in the building. Wouldn't it be more convenient to live on the ground floor?"

"The answer may be hidden in this room." Chen Ge looked up at the ceiling, unable to move his eyes away for a long time.

Seeing him like this, the other three policemen also looked up.

On the ceiling of Room 104, someone had carved four human faces out of sharp stones.

The four faces are in the four directions of east, south, west and north, with a little girl in the middle. The four faces are biting the little girl's limbs.

"What does this painting want to express? It doesn't look like something a child could draw."

The names of the two adults were Jiang Long and Zhang Chuyu, and the names of the two children were Jiang Bai and Jiang Xiaohu.

"Jiang Long? Isn't this the name of the investor who jumped off the building? How did someone write it here?"

"These seem to be the names of his family of four." Tian Lei thought for a while and said, "I guess the owners are venting their resentment on Jiang Long. After all, he is the developer."

"Even if the owner has lost his mind, he probably won't vent his hatred on a dead person. Besides, the content of the painting is Jiang Long biting someone." Team Leader Yan looked at the painting above his head: "The handwriting is childish, as if it was written by a child. However, the child certainly can't reach the ceiling, and there is no place to step on in this room."

The three policemen were thinking about various possibilities, but Chen Ge entered the bedroom alone at this time. He had to control his expression.

He was the only one among the people present who knew that Jia Ming had been possessed by Jiang Long. The appearance of the names of Jiang Long's family of four in the room further confirmed Chen Ge's guess. Jiang Long occupied Jia Ming's body, most likely for Room 104.

"Is there anything different about this room?"

Chen Ge searched for a long time but found nothing. He stood up and looked out the window. Standing in this position, he could vaguely see a large dark building in the distance.

"Liwan Town?"

There was not a single light in Liwan Town in the dark night, it looked like a dead city.

"I still can't figure out what Jiang Long is going to do. If Captain Yan hadn't insisted on coming over, I would have probably controlled Jiang Long by now."

Chen Ge glanced at the buildings nearby, and suddenly found a problem.

The four buildings are located in the east, south, west and north, all with 19 floors. The tenth floor is right in the middle, and there are four rooms on each floor. Room 104 is located at the westernmost location.

"The layout of the four buildings is very similar to the positions of the four faces. Jiang Long's face is also at the westernmost side, which matches the position of Building No. 1." Chen Ge went out to take another look at the painting: "Why did they bite that girl? If each face corresponds to a building..."

Chen Ge couldn't figure it out, so he subconsciously went to the westernmost side of Room 104.

After moving the garbage off the ground, Chen Ge discovered that the color of the ground here was different. He found some heavy objects in the house and smashed the area, cracking the thin layer of cement on the surface as the police looked at him in confusion.

"It's empty indeed." Chen Ge reached his hand into it and felt as if he touched something. It was not soft, but not too hard either. He grabbed the thing completely out.

The moment he raised his arms, all the police officers in the room, including himself, were stunned.

The shadow suddenly changed into the shape of a woman, but Chen Ge was unaware of it at this moment. He looked at the slender, pale arm wrapped in plastic wrap that he had grabbed, and turned his head with difficulty to look at the policemen.

To be honest, he didn't expect that there would be an arm hidden inside.

"Don't move! Put it down slowly!" Captain Yan was the first to speak. He slowly approached with a flashlight in hand and picked up the tightly wrapped arm. After just a few quick glances, Captain Yan seemed to have confirmed something: "Tian Lei, have your people get here within 20 minutes! Li Zheng, notify the criminal investigation team on duty to come to Dongjiao Mingyang Community immediately! Be ready to take over the dismemberment case!"

"yes!"

After giving the order, Captain Yan's expression eased a little. He asked Li Zheng for a cigarette and handed it to Chen Ge: "Are you scared? Go outside and have a cigarette to calm down."

"No thanks." Chen Ge didn't take the cigarette. He looked very unhappy. "Captain Yan, do you remember when we first came to Mingyang Community, I asked Captain Tian a question?"

"What's the problem?"

"Why is the room number on the 10th floor of Building 1 104? If this is the arrangement, how are the numbers of the other buildings arranged?"

"Yeah, I remember. What's wrong?" Captain Yan didn't quite understand what Chen Ge meant.

"There are four buildings, each with nineteen floors and four rooms on each floor. Normally, the numbers should be four digits. For example, the number of Room 1 on the eleventh floor of Building 1 is 1111. But Captain Tian said at the time that the four buildings were a whole, and the builders were also planning to build a corridor at high altitude to connect the four buildings, so the number representing which building was omitted." Chen Ge tried his best to express his meaning.

"What exactly do you want to say?"

"Look up." Chen Ge pointed at the painting on the ceiling. "We found the left arm of the body in the west building, which corresponds to the picture. If the four buildings are a whole, then does Mingyang Community represent the girl whose face was bitten in the picture? And are the other parts hidden in the corresponding rooms on the floors?"
