Number 10 might be an acquaintance who helped Chen Ge, or he might be a mentally ill person in disguise. If he wanted to find the answer, he had to go to the Linjiang Blood Prevention Station in person.

After making sure that nothing else was missed, Chen Ge walked out of the room, crossed the long corridor, and returned to the elevator entrance.

"There must be other secrets behind those closed security doors. Maybe the secret passages that the association members used to leave are hidden in them." Chen Ge regretted not bringing a skull crusher with him. Otherwise, he would have tried to break open all the doors. "Learn from this lesson and be more careful next time."

Entering the elevator, Chen Ge watched the numbers slowly change, and his nerves finally relaxed. He tied the butcher knife to his calf, took off the skull-crushing doctor's mask, and took a deep breath.

The elevator opened on the first floor. Before Chen Ge walked out, he heard someone talking outside in a stern voice.

"How did he get in? I ask you how did he get in!"

"Manager Huang, I really don't know why he appeared in the residential building."

"The murderer has sneaked in! Don't you know?"

"sorry."

"I paid you to come protect the property owner! I'm not here to listen to your apology! How many things have happened in the past few days? Just do the math yourself!"

Chen Ge glanced outside the elevator and found that Zhu Xiu, who he had thrown into the corner, was gone.

"Where is he?" Chen Ge looked into the distance and saw Gu Feiyu wearing a security uniform, holding his phone, with his head down.

Standing opposite him was a young man who looked very gentle but actually had a very bad temper.

"Xiao Gu? What's going on?" Chen Ge walked over.

"Who are you?" The middle-aged man looked at Chen Ge: "I don't know you. You are not a resident here, right?"

After he finished speaking, he glared at Gu Feiyu fiercely: "He is your friend?"

There are clear regulations that strangers are not allowed to enter or leave the community after midnight. Gu Feiyu knew that he had made a mistake again. He took off his hat and nodded.

"Manager Huang." A police siren sounded outside the building, and a middle-aged man in plain clothes walked in: "That's my friend."

Seeing this person coming in, Chen Ge was very surprised: "Captain Li?"

"I noticed something was wrong with you when you came out of the police station. I didn't expect you to be so capable. This guy was hiding so secretly, but he was still found." Captain Li pointed at the entrance of Building No. 3, where Zhu Xiu was lying on the ground unconscious.

"Have you been following me since I came out of the police station?" Chen Ge didn't notice anything at all. He felt a little scared when he thought about it now.

"I've been a police officer for almost 20 years. It would be strange if I was discovered by you who was completely unprepared." Captain Li said to Supervisor Huang, "You don't have to blame this young man. He did a good job. The criminal this time was very cunning and had a strong anti-reconnaissance awareness. Even our plainclothes officers failed once. It's normal that he didn't notice it."

"Even plainclothes police failed?" Supervisor Huang looked at Chen Ge and quickly apologized. His expression changed like turning the pages of a book: "Then this person is also a policeman, right? Thank you for your hard work, police comrade."

Chen Ge ignored him and looked at Captain Li with a guilty look on his face: "You have been guarding outside the building this whole time?"

"Nonsense, I waited for you at the entrance of New Century Park for an hour and a half, then followed you to Fanghuayuan Community, and have been waiting outside the building until now." Captain Li flexed his arms: "When I saw you find the suspect just now, I was ready to come over, but who knew you took the elevator upstairs again."

"Uncle Li, it's very dangerous for you to do this."

"If I wasn't afraid that you would do something stupid out of impulse, do you think I would have the time to care about you?" Captain Li lowered his voice and pulled Chen Ge aside: "Zhu Xiu seems to have been stimulated by something. Was he like this when you saw him?"

Captain Li's tone was a little strange. Chen Ge looked at Captain Li's expression and suddenly came to his senses. He insisted: "He was already like this when I saw him. The reason why I left him in the corridor and went back was to go upstairs to find out the reason."

"Yeah." Captain Li nodded: "This is very strange."

Not long after Zhu Xiu was put into the police car, an ambulance drove over and also stopped outside Building No. 3.

Several people in the room looked at each other.

"Who of you called the emergency number?"

No one admitted it. After a while, the numbers on the elevator display suddenly began to change and finally stopped at the thirteenth floor.

"Residents in the building rarely use the elevator at night. Something must have happened." Manager Huang and Gu Feiyu ran to the elevator door at the same time. Not long after, the elevator door opened to both sides, and a middle-aged man ran out in a hurry carrying an old lady on his back.

"Doctor! Doctor!"

The middle-aged man's mother seemed to have fainted due to a sudden illness. Chen Ge didn't pay much attention to it at first, but when he looked at the old woman's face, a hint of surprise flashed in his eyes.

This old lady is the one on the 13th floor who is about to take the elevator downstairs!

At that time, she looked into the elevator and muttered - why are there so many people in the elevator so late at night? It's full.

The old man's attire was completely different from what Chen Ge had seen. He was not sure whether the person coming down the stairs was the old man or his soul.

"She should be able to get through this by not taking the elevator."

After the ambulance left, it was time for Chen Ge to leave, but he had one more thing to do before leaving.

"Xiao Gu, how much can they earn in a month if you work as a night security guard?"

"A little over three thousand."

"I think you are very brave and have a good personality. If you don't want to be a security guard in the future, or have nowhere to go, you can come to the New Century Park in the western suburbs to find me." Chen Ge raised his mobile phone: "I will contact you by phone then."

Gu Feiyu showed obvious excitement this time: "Okay."

After saying hello to Captain Li, Chen Ge rushed back to New Century Park. Only after returning to his own haunted house did he completely relax.

"It's still comfortable here."

He wrote down the things that needed attention, memorized them again, and then burned them all.

"Tomorrow is a new beginning. After the business is closed, if you have time, you can go to the Linjiang Blood Prevention Station at dawn."

It was already very late. Chen Ge fed the white cat some cat food and was about to fall asleep. But before he had even laid down for long, his cell phone rang again.

"Is that Captain Li?" Chen Ge thought that something had happened to Zhu Xiu again, but after answering the call he found out that it was Captain Yan calling.

"Excuse me, Chen Ge, we have something we want to confirm with you."

Captain Yan was very polite, so Chen Ge couldn't refuse: "If you have something to say, just tell me, but it's better to be quick."

"I have sent you the picture. You can take a look. We found this scene when we checked the surveillance cameras around Haiming Apartment."

The message was received successfully. Chen Ge clicked on the picture and took a look. It was a picture captured from the surveillance camera and had been processed for clarity.

There is a man in a sweatshirt in the picture. He holds a mobile phone in his right hand as if he is talking to someone, and holds a flyer of Chen Ge's haunted house in his left hand. Cigarette scars and small wounds can be vaguely seen on the back of his hand.

"Do you know the man in the picture?"
