Standing next to Chen Ge, Wen Qing did not dare to ask why. She was worried that walls had ears and others might have heard some important information.

"You and Granny Li should stay in the living room first."

Chen Ge stayed alone in the bedroom. He closed the door, squatted beside the bed, and checked the boy's body.

The burn marks from the electric shock and the bruises from the beatings. Chen Ge's eyes finally stopped at the boy's neck. "He was strangled to death by an electric wire. There are sawdust left under his fingernails. Before the boy died, his arms were tied to the bed..."

Chen Ge untied the ropes on the body and covered the boy with a clean sheet. "On the surface, the electrician is a quiet, harmless, low-level worker. In fact, he is more irritable than ordinary people. He just keeps all his anger in his heart and vents his dissatisfaction by bullying the weaker ones. He is a thug at heart."

The electrician's situation was not an isolated case in the building. Chen Ge began to think more deeply: "Under the constraints of morality and law, their true nature is hidden, but in the world behind Xiang Nuan's door, the worst part of their character is completely exposed. This door seems to amplify the malice in human nature, making everyone become twisted and terrible."

Chen Ge tried to guess what the ghost fetus was thinking, but unfortunately there were too few clues and he had no idea.

Flipping through his backpack, Chen Ge discovered that blood had begun to appear on the comic book. He tried to call out to his staff, but still received no response.

"Chen Ge!"

Wen Qing's voice came from outside the bedroom, and then the bedroom door was pushed open: "Something seems to have happened downstairs!"

The corridor was filled with the sounds of running, shouting, and crying, creating a chaotic atmosphere.

"Don't worry, let them make a fuss for a while longer."

Chen Ge walked out of the room slowly. The faces of the neighbors flashed through his mind: "Who will be the next one?"

Several people came to the second floor. There was a faint smell of blood in the air, and fresh bloodstains could be seen on the stairs.

"What's going on?" Chen Ge heard Aunt Ding crying before he got close. Other neighbors gathered in the corridor, blocking the road tightly.

"The electrician is dead." Xiao Sun leaned on the steps, his face pale.

"Dead?!" Chen Ge looked very surprised. He quickened his pace and walked through the crowd: "Get out of the way!"

Standing at the corner between the second and first floors, Chen Ge seemed to be stunned. He saw Aunt Ding lying on the ground, crying out Jiaqi's name, her hands and upper body covered in blood.

Aunt Ding seemed to have lost her mind due to excessive grief. No one could approach her, or no one was willing to approach her now.

"You... killed him?" Chen Ge's pupils trembled: "He is our only clue!"

"Jiaqi is the first child I adopted. He disappeared in this community! I have been looking for him!" Aunt Ding, with disheveled hair, pressed her hands on the blood on the ground: "That's my child. Can you understand my feelings as a mother? Do you know how I felt when I saw that child..."

Aunt Ding burst into tears. She seemed to have lost all her strength and fell in a pool of blood.

"It's true that we can't say that Sister Ding killed him. I saw with my own eyes that Sister Ding had a conflict with the electrician. They both fell down the stairs, and the fruit knife just happened to pierce the electrician's neck. This is also called karma for evil." The person who spoke was a tenant on the fifth floor. He was very tall and always stood with Aunt Ding. This was his first time communicating with Chen Ge.

"A surprise?" Chen Ge looked past Aunt Ding and towards the corridor on the first floor.

The electrician had already run out of the corridor. His body was at the entrance of the corridor, and bloody handprints could be seen on the locked iron door.

"There's a knife stuck in his neck. Even if he's not dead, he can't speak. It's a pity that the clues we found with great difficulty are gone." Chen Ge's tone was quite helpless. He glanced at the tall man and asked, "What's your name?"

"My last name is Li."

"Why do you smell like medicine?"

“I’m a pediatrician.”

"Does the smell of medicine used on children have such a strong smell?" Chen Ge changed the subject without waiting for the other party to reply: "I was not there when the electrician died. Did you hear what he said at the end?"

"He called Aunt Ding's full name..."

Xiao Sun wanted to say something else, but was interrupted by Doctor Li: "The electrician is dead now. We must confirm as soon as possible whether he is the murderer of Qu Gui."

"But..." Xiao Sun insisted on speaking, but was interrupted by Chen Ge again: "Yes, the most urgent task is to catch the murderer first. If the electrician is the murderer who killed Qu Gui, then everyone will be happy. I am now worried that the electrician is just an accomplice, and the real murderer is still hiding in this building."

Living people were being killed right before our eyes, and the atmosphere in the building became increasingly depressing.

"I'll take Aunt Ding back to her room first. She saw her adopted son's body and was very shocked today." Doctor Li wanted to help Aunt Ding up from the pool of blood, but he failed after several attempts. He looked at the crowd and waved to one of the short men: "Big Head, come and help me."

The short man had no hair and a large area of ​​swollen face, looking a little deformed.

Datou and Doctor Li helped Aunt Ding to the fourth floor, while Chen Ge silently watched their backs.

"Doctor Li is tall and looks very strong. It's impossible that he couldn't help Aunt Ding. He was just looking for an excuse to ask Datou to leave together. The three of them should know each other and be a group."

Chen Ge suspected that Dr. Li, Datou, Aunt Ding, and the electrician were the four who teamed up to kill the landlord and stole the keys to all the rooms.

As for the reason why they killed the landlord, Chen Ge roughly guessed it. The landlord had peeped into their secret, so the landlord must die.

"Um... what to do with the electrician's body?" Qu Ying was now having a headache. Qu Gui's body was still lying in the living room, and now there was another body in the building. Their original intention was to track down the murderer, but things inexplicably began to get out of control, as if someone was secretly doing something and wanted to kill all the tenants in the building.

"Don't worry about the electrician's body for now. I just made a horrible discovery." Xiao Sun saw that Dr. Li and the others had walked away, so he dared to speak: "The electrician was pushed down the stairs. The person who did it was not Aunt Ding, but Dr. Li. They were the two running in front at the time."

"Jiaqi is Aunt Ding's adopted son. Why is Dr. Li so impulsive? He doesn't look like a man with a strong sense of justice." Chen Ge was slowly guiding the neighbors' thinking. He couldn't be too blunt like Xiao Sun, because he didn't know how many other people in the building were involved in the murder of the landlord.

But one thing is certain, there shouldn't be too many people involved in the murder of the landlord, otherwise they would have no need to be afraid of Chen Ge, let alone sacrifice the electrician.

"I find it strange, too." The middle-aged man who hid women's underwear at home stood alone in the corner. Now he didn't trust anyone: "The woman surnamed Ding was not right today. She usually treats her adopted son very badly. It's more like raising a pet than raising a child. She beats and scolds him when she is not satisfied."

"So you think Aunt Ding killed the electrician not to avenge her adopted son? But because she was worried about something else?"

"I didn't say that!" The middle-aged man looked at Chen Ge and waved his hands. He was an old tenant here and knew that talking nonsense could sometimes lead to disaster.

"Why don't we go ask Wu You? He's the kid who lives in 301. The neighbors in the building say that the kid loves to lie, but I think the kid is actually a good person. It's just that he may have some psychological problems because he has no one to accompany him for a long time. Don't we have a psychologist here? You can help take a look at him." Xiao Sun suddenly spoke, scaring the middle-aged man into a cold sweat.

"Wu You is a full-mouthed liar. You can't believe a word he says. Besides, he's just a little kid. What does he know? Let him see the corpse. Don't scare him directly." The middle-aged man shook his head pretending to be calm.

"Okay, I'm just offering a suggestion. After all, that kid is always running around in the building, so maybe he knows something." Xiao Sun was analyzing rationally. He had no idea that he had become a thorn in the eyes of most people.

Chen Ge also wiped the sweat from his forehead. As an ordinary person involved in a murder case, the first thing he should do is not to learn to solve the case like a detective, but to protect himself.

He understood Xiao Sun's behavior of repeatedly jumping on the edge of death, but he did not agree with it.

"I also don't think it's necessary to question a child, but the killer is hiding in the building. It's too dangerous to let Wu You stay at home alone. It's better for him to stay with us." When Chen Ge said the first half of the sentence, the middle-aged man nodded, but when he heard the second half of Chen Ge's sentence, his head froze.

"Will it be inconvenient to bring a child with you?"

"It's okay, I'll protect him. Let's go to 301 to pick up Wu You now." Chen Ge went straight to the third floor. As soon as he entered the corridor on the third floor, he saw a boy's face sticking out from the room at the end of the corridor. It was a bit scary at night.

"Wu You, there's a murderer in this building. It's not safe for you to be alone. Follow us first." Chen Ge wanted to hold Wu You's hand, but Wu You dodged.

"Murderer?" Wu You looked at Chen Ge and the tenants and said in a very childish voice, "Aren't you all murderers?"

"Look, this kid just knows how to lie." The middle-aged man spread out his hands, looking helpless.

"You know we are all murderers, so why are you still here? Aren't you afraid?" Chen Ge looked at the child in front of him.

"I'm waiting for Mom and Dad."

"If you get killed, your father and mother won't be able to find you, so it's better for you to follow me obediently." Chen Ge's way of reasoning with the child was extremely hardcore.

Grabbing Wu You's hand, Chen Ge asked him to follow him.

Seeing Chen Ge's firm attitude, the middle-aged man suddenly said that he was not feeling well and wanted to go home. Chen Ge did not stop him and let him leave.

In fact, Chen Ge knew very well that the middle-aged man left at this time because he was definitely worried that Wu You would let the cat out of the bag, so he was in a hurry to go back and destroy those shameful things.

After the middle-aged man left, the rest of the people walked together towards Aunt Ding's room on the fourth floor.

Doctor Li called Datou and Aunt Ding together, they must be discussing something, Chen Ge didn't want to give them too much time.

When Chen Ge arrived at the fourth floor, he saw Datou guarding the door of Aunt Ding's room before he even went over.

"Is Sister Ding feeling better?"

"With Doctor Li here, there should be no problem." Big Head looked strange, but spoke very kindly, giving people the impression that he was an honest man who was particularly easy to bully.

"Something happened after you left. I want to ask Aunt Ding in person."

"She needs to rest."

"You'd better get out of the way. This is a serious matter." Chen Ge was followed by Qu Ying, Xiao Sun, Wen Qing and Granny Li. They had the advantage in numbers. "I'll go in alone. I won't disturb Sister Ding's rest."

"Okay." Big Head knocked on the door. After more than ten seconds, the security door opened and Chen Ge walked in alone.

Although Aunt Ding is no longer young, the interior decoration of her house is very girlish, with pink as the main color.

As soon as Chen Ge entered the room, he smelled a strong scent of perfume and air freshener. He coughed lightly and took the initiative to close the security door.

Aunt Ding was lying on the sofa, and Doctor Li was standing beside her. When they saw Chen Ge come in, their faces didn't look very good.

"Are you okay?"

"Do you have any impression of that wretched middle-aged man on the third floor?"

"What's wrong?"

"He just said that the electrician didn't fall down the stairs by himself, but was pushed down by someone. Then he hinted to us to go ask Wu You." Chen Ge had a cold face.

"Did you find out anything?" Aunt Ding's face turned pale and her voice trembled.

"That child has been traumatized. We can't understand what he said. For example, Aunt Ding always carries the child up and down the stairs, and there are children appearing around him like ghosts, etc." Chen Ge seemed to be unable to see Aunt Ding's increasingly pale face, and said to himself: "The focus is not on this child, but on the uncle on the third floor. He lives opposite Wu You. I doubt that he taught Wu You to say these words. After all, even if a child loves to lie, he won't always say these things."

"That makes sense." Doctor Li and Aunt Ding nodded at the same time.

"In addition, I discovered one thing. That uncle always seems to interfere with our search for the truth. I suspect..." Chen Ge raised his head, his eyes bright: "Could he be the murderer who killed the landlord?"

"It's very likely. There are many strange things about that person." Aunt Ding's face became a little redder and she spoke more fluently: "He has a lot of women's underwear at home. I don't know where he got them from. Anyway, that person is very disgusting."

"You suspect him, and he wants to lead the matter to you." Chen Ge hesitated for a while: "I don't know who to believe. Let's do this. We will pretend to go to a room on the third floor to check, and then go directly to his house for a surprise inspection to see if we can find any evidence. If there are items related to the landlord's murder in his house, then we can be sure that he is the murderer of the landlord."

Chen Ge is very bold. His real purpose in doing this is to make the murderer produce the evidence himself. This is a chain trap.
