One night, Jiang Chenghuan invited Zhou Yin to his office. There are some situations that need to be checked with him.

It's a full moon night, bathed in clean moonlight along the way. When he arrived at the gate, Zhou Yin was already waiting there, and for some reasons that did not need to be explained, the doorman did not let him come in first. He said hello, and Zhou Yin followed him to the door of the office. Jiang Chenghuan took out the key and opened the door of the office, the table was sprinkled with moonlight, and he stood at the door and looked like a white frost. Jiang Chenghuan walked in quickly and turned on the lamp. The temperature was a little cold, not much worse than that on the Broken Soul Slope that night. Because of looking for Zhou Yin, he naturally thought of Ma Kaili, and thought of the situation lying upright on the Broken Soul Slope that night, and he couldn't feel a chill in his heart.

Under the night, Zhou Yin's figure seemed to be not so certain, and he always felt that it was swaying in front of him, flickering, and he really wanted to reach out and touch his face to confirm. He shook his head, smiled helplessly, secretly scolded himself for being insane, and hurriedly bent down to plug in the electric barrel. When it was over, I ran to make a cup of hot tea, then turned around and brought it over.

Clinker, as soon as he turned around, met Zhou Yin's flurry gaze. Zhou Yin's eyes wandered and dodged, and his heart chuckled unconsciously. Because, under the desk lamp, the gaze just now looked a little hideous, and the expression on his face was not so frank, what made him even more incomprehensible was why this man showed such a gaze and what he was thinking.

"Why don't you bake the fire?"

Zhou Yin asked and sat down silently. He didn't answer, still staring at him.

He knew it was time for him to speak, after all, he had called someone else.

Well, well, it is said that it is inconvenient for our police to intervene in your family's affairs, but there are some things that I think it is still necessary to intervene appropriately. I'm looking for you today, just to communicate, if you find it convenient, just say a little, otherwise, it's okay not to say it. In short, when the person returns home well, everything is fine, and nothing else matters.

Speaking of this, Jiang Chenghuan stopped and looked at Zhou Yin, as if waiting for his statement.

However, Zhou Yin did not speak, but continued to look at him. That expression seemed to have told him, well, it doesn't matter, you go on and want to know something, just say it.

Well, that's the case, your wife Ma Kaili is in danger this time, thank God, but at the same time, I have questions, I don't know what you think. I also came to you for this reason, and I hope you can cooperate with us to figure out some key issues. At this point, he paused again, but quickly continued. He said, for example, what was the reason for being unconscious in the middle of the night on the Broken Soul Slope. Although there is an explanation, but, to be honest, we still don't believe it, I don't know what you think. Another example,...... When Jiang Chenghuan said this, he hesitated again and did not continue. Originally, he was going to talk about the black shadow, and he wanted to say what was going on with the black shadow. But when the words came to his lips, he suddenly thought that Zhou Yin actually didn't know about this matter, and it was always bad to say it, so he simply stopped abruptly, and turned away from the topic and talked about other aspects. For example, he said, when he was a child, he was frightened and left with sequelae, and he wanted to know more about these things.

Zhou Yin listened silently, but still did not respond, he stared at Jiang Chenghuan with a scrutinizing gaze with a thoughtful expression.

This made Jiang Chenghuan a little embarrassed, and he was at a loss for a while, not knowing how to deal with this kind of scene.

Zhou Yin rubbed his hands suddenly, and then stretched out his hand to the electric stove while looking back at the whole room. Obviously, these abnormal manifestations are actually a preparation for speaking. But at this critical juncture, an unexpected scene happened.

Jiang Chenghuan suddenly heard a crisp and rhythmic knock outside the door.

"Knock, knock, knock"

They both looked at the closed door.

Although it was still early, and although there was still an old man on duty at the gate, the knock on the door still startled the two of them.

There seemed to be only the two of them in the whole building, the corridor was pitch black, and more importantly, Jiang Chenghuan was thinking about the scene on the Broken Soul Slope in his mind, and his heart was hanging.

"Who, who?"

Jiang Chenghuan roared, but Zhou Yin on the side trembled. Obviously, Zhou Yin didn't have this intention to prepare.

However, there was no response from outside the door, Jiang Chenghuan quickly stood up, walked straight towards the door, and reached out to hold the doorknob. He hesitated slightly as he held the doorknob, but opened it quickly.

The door was empty.

"Strange, why is there no one, who is it?"

He put his head out of the door, and as he spoke, he took a step back and closed the door again.

"What the hell is going on?" Jiang Chenghuan looked up at Zhou Yin, who looked puzzled.

Zhou Yin's answer was beyond his expectations.

"Do you believe there was a knock on the door?"

"Ahh

Jiang Chenghuan was taken aback, because he didn't expect Zhou Yin to say this at all.

"Isn't it an illusion?"

"Hallucination, what do you mean?" Jiang Chenghuan didn't understand at all.

"Are you sure you heard a knock at the door?" Zhou Yin then added.

"Didn't you hear a knock at the door?"

"No, I didn't hear anything."

"No, didn't you hear it just now, the knock on the door was clear. Otherwise, why don't you look at the door? ”

Hearing Zhou Yin say this, Jiang Chenghuan was a little lacking in confidence. Hell, when there was a knock on the door, why didn't he hear it? As he spoke, he sat down and stared at Zhou Yin with a puzzled look, his expression clearly said, how could you ask such a strange question.

"Actually, I didn't hear anything."

"Ah, how is this possible, no," Jiang Chenghuan was very surprised, paused for a moment, and then said, "Are you staring at the door?" ”

"I was attracted by your gaze, actually, I didn't hear a sound." Zhou Yin said very firmly, "I'm sure. ”

"Hey, that's, that's weird...... Could it be that I have heard the wrong thing? Jiang Chenghuan became less confident.

"It's weird, it's scary, but it's not strange at all," Zhou Yin's tone was very calm, "Once, I encountered such a thing, if you are interested, I might as well talk about it." ”

Jiang Chenghuan didn't squeak, it wasn't that he didn't want to hear it, but he felt incredible, it hurt his self-esteem too much, and he felt that if Zhou Yin confirmed what he had just said, he couldn't hold his face, but he still stared at Zhou Yin, his eyes didn't blink. Because, he really wanted to know.

Seeing this, Zhou Yin coughed, and then slowly narrated.

He said that in the place where he lived, there was a strange phenomenon, that is, in the dead of night, he could hear footsteps like slippers coming from the roof of the building, dragging them over his head, and it was repeated and haunted by him. At first, he didn't take it seriously, and soon after he realized that something was wrong, because he knew that there had been no one living upstairs, so how did this noise come about, the more he thought about it, the more he felt that he had no bottom in his heart, and he couldn't help but think of cranky thoughts in his mind, and even thought of ghosts or something.

He was reluctant to tell anyone about this feeling, because he was jealous and afraid that people would be laughed at when he said it. He had the mentality of luck, feeling that it would naturally pass after a while. However, the unmistakable sound of footsteps, which has never disappeared, is particularly frightening. Gradually, it seriously interfered with his life, and before he could get a reasonable explanation, his nervous system became more and more unbearable, and he suffered a nervous breakdown for a time.

One night, the voice rang out again, and he almost lost control, and ran upstairs with a flashlight in his hand to check, but found nothing. Strangely, the sound of the slippers disappeared. This strange situation intensified his fear, and the bright flashlight shone on any dark place from time to time, but he always felt that there was a pair of eyes staring at him all the time in an unseen place behind him. So he kept turning and turning again, lest he fall into some unseen corner.

Later, he couldn't take it anymore, and just before a certain night came, he waited early in the corner of the upper floor. In addition, he brought a bottle of liquor, a flashlight, and even, a knife. The bottle is for courage, the flashlight is for viewing, the knife is for defense, in short, he is out of the way.

Hours passed, and when it was time to speak each night, nothing happened. And he seemed to have passed several years, alone in the dark corner, a pair of eyes like nocturnal animals, always searching for all the targets in front of him, almost collapsing. Fortunately, it was in the dark in advance, and the feeling of fear was much better than suddenly coming to the dark place.

Apparently he was busy in vain, and when he turned on his flashlight and was dazed about to go downstairs, a strange scene happened. Suddenly there was a familiar voice in his ears, clearly the sound of slippers, and he was startled and pricked up his ears. But the voice was not in front of me, but in the next building, and the sound was so small that it was not easy to hear if you didn't pay attention.

He continued downstairs, not thinking it was the voice. However, as soon as he went downstairs, the voice seemed to grow louder, and it was always felt in his head. Gradually, he seemed to know what was going on, it was this voice, the sound of walking from the next building. The owner of the house had just moved in and liked to wear slippers, as long as he was at home, and he could hear them in the dead of night. Actually, the voice was not loud, but somehow, when Zhou Yin was alone in the room, he felt that the voice was quite loud, and even, he felt that the voice was above his head.

"Everybody has the experience of hearing something, and sometimes they are troubled, but in the end it turns out that it is not, it is an illusion, or an illusion, which is caused by psychogenic factors."

Zhou Yin said this and summed it up in one sentence.

Jiang Chenghuan didn't squeak, because he had indeed encountered this kind of situation. But he didn't think so about the knock at the door, he really heard it. He just didn't understand, why didn't Zhou Yin hear it. However, he couldn't argue and couldn't convince Zhou Yin with evidence.
