Stay away from beasts in the world of Siheyuan

The moon was bright and the stars were sparse. Su Yun's sister knocked on Xu Changping's door for a long time, but there was no response from inside the room. She couldn't help but complain to Deputy Director Zhou and the head of the security department who were waiting outside:

"Could this kid not be at home? Such a loud noise could bring a dead person back to life."

"He must be at home. Someone is helping me keep an eye on him. He hasn't gone out since he came back." The head of the security department saw that both of them were looking at him, and quickly spoke out to assure them.

"Otherwise, this kid is just feeling guilty and doesn't dare to come out." Sister Su Yun said with an angry look on her face.

"So what should we do now? Keep knocking on the door?" asked the security chief with a shrug.

He was invited by Deputy Director Zhou. Seeing that things were not making any progress and they could not force their way in, they began to back off.

"Chief Li, thank you for your help today. Let's go back to the backyard and have a couple of drinks." Deputy Director Zhou said with a smile when he saw the chief of the security department like this.

At that time, the steel mill was still a key unit, and the security department was independent. The head of the security department was invited by Deputy Director Zhou.

"Then let's go." The head of the security department looked at the two of them and said.

The three of them returned to the backyard. Sister Su Yun set out the wine and food for them and went back to the inner room to sleep.

Xu Changping heard the conversation between several people in the house and couldn't help but spit and said, "These plague gods are finally gone."

After practicing calligraphy for half an hour, Xu Changping quietly left the house and came to the backyard.

Hearing the sound of two people drinking and talking inside the room, Xu Changping glanced at the door that was not closed tightly and threw a sleeping pill in.

"3.2.1." Xu Changping counted three numbers outside the door, and then he heard two "plop" sounds coming from inside the door.

After opening the door and ignoring the two people lying on the ground, Xu Changping went straight to the inner room. Seeing Sister Su Yun sleeping on the bed, Xu Changping thought to himself: Since you want to know what happened to Su Yun so much, you can experience it yourself.

Thinking of this, he used his internal energy to condense needles at his fingertips and inserted them into several major acupoints on her head.

After doing all this, Xu Changping made the two men look like they were drunk and lying on the table, then he quietly left.

In the morning, Xu Changping was sorting out medical records when two people in police uniforms walked in.

One of the police officers, a pretty female police officer, asked Xu Changping seriously, "Are you Xu Changping?"

"Yes, what's the matter, comrade from the police?" Xu Changping was also confused. He didn't know why the police came to see him.

Seeing Xu Changping's confused expression, the female police officer calmed down a little and asked, "Where were you at 11 o'clock last night?"

"I'm at home!" Xu Changping said directly.

"Then why didn't you open the door when someone knocked on it last night?" The female police officer stared at Xu Changping as she spoke.

"I didn't hear anyone knocking on the door!" Xu Changping said innocently.

"The other party was knocking loudly outside your door for fifteen minutes. How come you didn't hear it?" The female police officer's tone became stern, and she looked at Xu Changping as if he was a bad guy.

"Comrade Public Security, can I ask what happened?"

Xu Changping felt very uncomfortable with her look and asked in an unpleasant tone.

The young female police officer glanced at the middle-aged police officer next to her, and after getting the other party's approval, she said:

"Last night, Ms. Su Hong knocked on your door for a while, then went back to sleep and became a little mentally disturbed."

"Wait a minute, you mean a woman knocked on my door for 15 minutes in the middle of the night, right? What did she want from me?" Xu Changping asked directly.

"According to the family's account, she suspected that you had done something to her sister, Ms. Su Yun, and she went to confront you on purpose."

The young female police officer also knew that this reason was untenable and said it hesitantly.

"She stopped me during the day to ask me about this matter. I told her clearly at that time that it had nothing to do with me." Xu Changping held his forehead with his hand and said with a sigh.

"But both sisters went to see you and became insane."

"Her sister didn't look for me. As for Su Hong saying that she looked for me last night, I really don't know. Maybe I wasn't at home at that time."

"You're not at home, then where did you go? You just said you were at home." The young female police officer seemed to have discovered a loophole in Xu Changping's language, and her tone was stern but also slightly excited.

"I have the habit of going to the toilet before going to bed, but I didn't pay attention to the time." Xu Changping glanced at the female police officer and said calmly.

"You are lying. We have investigated and found that you built a toilet inside the house when you renovated it some time ago." The female police officer became even more excited and shouted sternly.

"Comrade Public Security, my toilet is only used temporarily for emergencies. Besides, you can't use it." Xu Changping said to the female police officer with a smile.

"you...."

The female police officer looked at Xu Changping's expression and choked with anger.

"Me? What evidence do you have to prove that their affairs have anything to do with me? I am not familiar with that Su Yun at all. She only worked as a nurse in our infirmary for a day and a half before she was transferred away. I don't even know her sister."

Xu Changping teased the female police officer for a while, then became a little impatient. Since they had no evidence anyway, he spoke with a cold face.

"Okay, thank you for your cooperation. If there are any questions later, we will contact you again."

The female police officer wanted to say something but was stopped by the middle-aged police officer.

"Okay, come to me if you have any questions."

Xu Changping nodded, returned to his desk, sat down, picked up the medical record and started reading it.

"Master, this Xu Changping is clearly a major suspect."

After leaving the infirmary, the young female police officer complained to the middle-aged male police officer.

"Do you have any evidence? You said he is a major suspect, then what suspicion do you think he has?" The middle-aged male police officer glanced at the female police officer and said in a cold voice.

"I don't have any evidence, but the person who reported the case said that the problem occurred after the two of them knocked on his door and went back." The female police officer retorted dissatisfiedly.

"Do you remember what I told you when you started working here?" The middle-aged policeman's expression was already very bad, and his tone became stern.

"Remember, you must be fair and just...you must not break the law." The young female police officer glanced at the expression of the middle-aged male police officer and recited a bunch of regulations.

"Just remember these. Didn't I tell you not to trust the reporter's words too much? Especially this kind of person, most of their words are in their own interests."

"But...."

"No buts. I know what you're thinking, but do you know what the consequences would be if Xu Changping opened the door last night? Do you know how serious the crime of hooliganism is? If a man knocks on your door in the middle of the night, would you dare to open it?"

The middle-aged policeman looked at the young female policeman with disappointment and yelled.

"I understand, Master. I won't do it again next time." The young female police officer's face turned pale. She had not thought of this before and thought that Xu Changping had done something wrong by not daring to open the door at home.

Now she followed the middle-aged male police officer obediently, with her head hung like a defeated rooster.
