There was no car on the road at midnight, and the surroundings were eerily quiet. Occasionally a wild cat would stop by, but soon it seemed to sense something and ran away quickly.

"Who are you?"

The detective stood in the muddy back alley, his shoes missing, his feet on garbage, blood oozing from his wounds.

"You can't even recognize my voice?" The man in the shadows walked out slowly, holding a hideous and terrifying hammer in his hand.

The dim light elongated his shadow. The person speaking was clearly a man, but his shadow was the shape of a long-haired woman.

The investigator saw the man's face clearly. He clenched his teeth and squeezed out two words: "Chen Ge!"

"I don't know you at all, but you can call out my name. It seems that I was right." The man blocking the exit of the back alley was Chen Ge. He and Captain Yan searched the entire Building No. 3, but failed to find the last hidden murderer.

Chen Ge began to suspect it at that time. After asking Captain Yan about the hospital that accepted the investigators, he returned to New Century Park, took the skull crusher and quietly ambushed in the hospital.

"How did you find me?" When the time came, the investigator calmed down instead. He stared at Chen Ge's face with a strange smile on his face.

"Why should I tell you?" After pressing the switch of the recorder, Chen Ge walked into the back alley with a hammer in both hands.

"Killing me won't do you any good. This is just a will hidden in my substitute ghost. Besides, don't forget that I am in the body of a policeman now." The investigator was indeed shocked when he first saw Chen Ge, but he quickly calmed down: "If I die, this policeman will be buried with me."

Chen Ge was too lazy to talk nonsense. The phone in his pocket was recording all the time, and all the conversations between the two were recorded in it.

Looking at the ferocious hammer approaching, the investigator's mouth twitched slightly. Chen Ge's cold expression seemed to tell him that everyone was not a good person and he should stop threatening them with such despicable means.

"In fact, we can still have a good talk. Aren't you curious about my identity? Don't you want to know who I am?" The patient was making his last effort. He wanted to communicate with Chen Ge, but from Chen Ge's attitude, it seemed that he was not prepared to pay attention to him.

Seeing Chen Ge approaching, the patient changed his words again: "Don't you want to know who the president of the Ghost Story Association is?"

"Who is the president? This is a multiple-choice question, and I am now using the process of elimination to solve this problem." Chen Ge told the investigator tactfully that he was afraid he would not survive the night.

Chen Ge was not planning to really kill him. The reason why he came here secretly without Captain Yan's knowledge was that he had other plans.

He planned to take the investigator back to the haunted house and interrogate him slowly.

How does the saying go? There is strength in numbers.

"Detain him first, and then hand him over to the police." Chen Ge said this only because his phone was recording. His real thought was to just break his legs first and save his life for the time being.

The investigators could not find any flaws in Chen Ge, but his expression did not change much, as if he still had some cards up his sleeve.

"Chen Ge, you will definitely be interested in what I am going to say next. As long as you let me leave, I will tell you how the door was formed, and how to close and open it." The investigator had a strange expression, as if he was smiling but not smiling. He seemed to be sure that Chen Ge would be tempted.

"Think about it carefully. You should know the value of this information." The investigator looked calm, but his body still took two steps back unconsciously: "The one controlling this policeman is just a substitute ghost, which contains one-third of my will. Even if you kill him, I will not be harmed."

"If you won't be hurt, then why are you in such a hurry to leave?" Chen Ge slowed down: "Let me see your sincerity. This is the premise of the deal."

Seeing that Chen Ge was finally interested, the investigator breathed a sigh of relief: "Since you want to know about the door, I guess you should know the location of a door."

"That's right." Chen Ge did not deny it.

"The reasons for the doors to appear are very complicated, and no one can explain them clearly yet. I only know that they are usually concentrated in places with deep resentment and few people. However, the external environment is only a prerequisite. The most important reason is that there must be someone knocking on the door."

"Who's knocking?"

"The world behind the door is blood red, filled with despair and destruction, and the accumulation of all kinds of negative emotions in people's hearts. It is opposite to the human world, and it gathers countless nightmares." The investigator's voice became a little erratic: "Normal people can't see that world. Only those with a broken personality and who have lost all hope have a chance to push open this door."

"I once heard the first person who pushed the door say that he did not do anything extra that day, just like usual. He pushed open the door he often entered and exited. But the world behind the door became completely different. The door appeared suddenly without any sign."

"No signs?"

"Yes, you own a door, and you must have had similar experiences. For example, when you stand outside the door, you will hear..." When the investigator was halfway through his speech, sirens suddenly sounded outside the alley, and several police cars came roaring in!

"Did you call the police?" The smile on the investigator's face slowly faded.

Chen Ge shook his head: "Go on, tell me the information behind the door, I can help you cover it up."

"Really?" The investigator smiled coldly.

"You can try. You don't have any other choice now." Chen Ge looked around, looking for a place to hide the skull crusher.

"Living in hell, do you think the devil will believe the devil's words?" The investigator turned and ran towards the hospital, with Chen Ge chasing closely behind.

"Don't move!"

A police car also drove up from the other side of the alley, completely blocking the investigator's way. He did not stop and rushed into the hospital without hesitation.

"Take advantage of the complex terrain to escape? Or do you want to kidnap a hostage?" Chen Ge chased after him, and soon he found that he had underestimated the investigator's ruthlessness and decisiveness.

“Bang!”

Kicking open the security door, the madman ran directly to the roof of the hospital.

"Don't come over!" The investigator stepped on the guardrail and stood on the edge of the hospital building!

The night wind blew his hospital gown. The city was beneath his feet. He stood in the darkness, looking down at everything.

Chen Ge, who was chasing the investigator closely, stopped three meters in front of the investigator and did not continue to put pressure on him.

"Chen Ge, I remember your name. Next time we meet, I will give you a surprise." The investigator smiled again. He looked at Chen Ge and slowly opened his arms.

"Yao Qingyi!" The security door on the roof was knocked open, and Captain Yan and other people from the Municipal Branch rushed up.

Seeing them, the smile on the investigator's face became even brighter, and his body slowly lay back, as if the endless darkness was his destination.
