If you don't do something shameful, you won't be afraid of ghosts knocking at your door." Although there was a limit to what Han Chun Sheng said, his behavior had exceeded what a normal person should have. It was more like he was doing something shameful …

Was there a connection between the "well-deserved" words left on Luo Mu's corpse, the "enlightenment" note left on Yang Wenzhao's doorstep, and the paints written on the paper were all from Han Chunsheng's study. Now Han Chunsheng was frightened by the invisible words in his study?

Suppose there really were words on the wall, but for some reason, only Han Chun Sheng himself could see them. Then, who was the person who left these words?

Could it be that Han Chun Sheng wasn't a person who broke into the police station at night, but a victim?

Also, when did the other party leave these words behind?

Before dinner, Han Chunsheng was in his study reading a book. He put the book down and went out when it was time to eat, and at that time he should have looked at the wall, but he did not show any unusual reaction. Was it because he did not notice the words on the wall, or were there no words on the wall at that time?

In terms of time, it was possible.

However, I can't be sure if there are any words on the wall or not. If there were words, what was even more unfathomable was how the other party had done it, leaving behind words for Han Chunsheng to see but not for us to see.

We examined the wall and found no problems...

The words that can only be seen by Han Chunsheng, Han Chunsheng, Han Chunsheng, and Han Chunsheng on the red wall of the study...

What's the connection?

Han Chunsheng is very smart and very conceited. From his previous performance, I thought he was the same as us, a semi-finished experiment. I even suspected that he was the guy that sneaked into the police station to practice calligraphy on Romu's corpse.

After studying in the study for a long time, they were unable to come to a conclusion.

Xu Haoqing: "Let's go out and see Director Han."

Returning to the living room, Xu Haoqing asked, "Director Han, explain what's going on clearly. Only then can we help you."

Han Chun Sheng looked as if he still had some lingering fear as he quickly shook his head. "I already said it, why are you still holding on to it? It's just a joke. What, is there a problem? "

His mood was unstable, and his tone was not friendly. It was as if his fear had turned into anger.

Xu Haoqing frowned slightly, "Director Han, if you don't work together like this, we won't be able to …"

"Cooperate with what?" I already said that everything is fine, are you done yet? It's getting late, we need to rest, please go back. "

Han Chun Sheng ordered for the guests to leave. Zhang Yingying was a little worried, but she couldn't go against his orders.

She leaned over and whispered, "Captain Xu, Shu Jing, Li Fengyun, all of you should be fine now. You should go back. I'll accompany him here."

That said, I was not at all at ease.

Xu Haoqing called Zhang Yingying to another room, and they chatted for a few minutes before coming out. No one knew what he was talking about.

Li Fengyun winked at Zhang Yingying, "Why don't I stay and protect you?"

Han Chun Sheng glared at him and snappily said, "Li Fengyun, I appreciate your kindness. Say it again, please go back."

Xu Haoqing left a phone call to Zhang Yingying, telling her to call him if anything happened.

Even though everyone was extremely unwilling to leave, but from the looks of it, we don't have any evidence of Han Chunsheng's crime. Although Xu Haoqing is the captain of the Criminal Police, he couldn't possibly take any forced measures to stay here.

I have a feeling that Han Chunsheng has a lot of secrets on him …

Paint, study, words on the wall...

What other secrets did Han Chunsheng have?

He was so scared tonight, it was unlikely that it was just a self-directed prank. He had to throw out smoke bombs to disguise himself as the victim, right?

It shouldn't be necessary, and even if he did, he wouldn't be able to clear himself of suspicion.

Returning to the car, Xu Haoqing asked me to repeat what I saw. This time, I told it very carefully. Xu Haoqing also listened very carefully. Only Li Fengyun used his binoculars to observe Han Chunsheng's home.

After finishing the narration, I looked at Han Chun Sheng's home. At this moment, there was no longer any trace of Han Chun Sheng in the study room. Even the lights were turned off.

The main bedroom on the side had drawn the curtains, which didn't have a very good shading ability. Through the curtains, one could see a graceful figure on top, that was Han Chunsheng's lovely wife, Zhang Yingying.

Xu Haoqing: "That's weird, the situation in front of us is such a mess. Just when we found out about Han Chunsheng, Han Chunsheng suddenly became confused and confused as if he just bumped into an evil being, and decided not to let us stay and protect him. Sigh, I really don't know what he is thinking. Shu Jing, just as you said, I also feel that Han Chun Sheng's mind is clear. He wasn't hypnotized by anyone or took some hallucinogenic drug.

"That's right. I don't know what the words are like or what the content is about. To be able to scare the chattering Han Chun Sheng to such an extent." Boss, what are you looking at? "

Li Fengyun was still looking through the binoculars as he said, "Don't be noisy, I'm looking at Zhang Yingying."

Xu Haoqing had a sullen look on his face, "Feng Yun, what time is it? If you don't try to find a way, why are you still looking at beauties?"

"Looking at beauties? Don't you guys think that this beauty is a little special? " Li Fengyun said softly. From his tone, it seemed that there was something in his words.

"Boss, what do you mean?" I asked.

"Her husband was scared half to death. As his mistress, he didn't seem to show his due fear. She knew Captain Xu's identity. Shouldn't she ask the police for help in this situation? But she didn't. Although there was also a look of alarm on her face, to a certain extent, she didn't show it enough. "

After hearing what Li Fengyun said, I had the same feeling.

Xu Haoqing nodded and passed a cigarette to Li Fengyun, "Fengyun, I was wrong about you. Are you suspecting Zhang Yingying?"

Li Fengyun said, "It's a little bit, I keep having the feeling that Zhang Yingying's reaction wasn't intense enough. Judging from the daily contact and the scene Shu Jing told me about when they were eating, the relationship between the two of them should be very good. For such a couple, no matter how calm the wife is, even if she's scared half to death, she shouldn't drive us away without doing anything. At the very least, she should take Han Chun Sheng to see a doctor, right?"

"It's not without reason. Although I can't be sure that Zhang Yingying was involved in Han Chunsheng's shock, but from the looks of it, she really is suspicious." Also, Shu Jing, from your narration, after Han Chunsheng and his wife finished their meal, Han Chunsheng very consciously went to wash the dishes. He washed very earnestly and attentively, and for ten minutes, that is to say, you stared at him for over ten minutes, right? " Xu Haoqing said.

"Yeah, of course I have to keep an eye on him."

"In the past ten minutes, where has Zhang Yingying been, and what did she do?" Xu Haoqing asked again.

"Uh, I should be reading in my bedroom …"

"Should? You're not sure, are you? Because you were staring at Han Chun Sheng, if Zhang Yingying didn't immediately return to her bedroom to read, and instead went to Han Chun Sheng's study room to work, you would have no way of knowing, right? "

Xu Haoqing's question made me realize that I had made a mistake.

Indeed, my target had always been Han Chunsheng. I watched him from the south while he was reading in the study, and I watched him from the north as he ate in the dining room, and I watched him as he washed the dishes.

This way, I ignored Zhang Yingying.

When Han Chun Sheng finished washing the dishes, I returned to his study room to continue reading. I turned south and saw Zhang Yingying reading in his bedroom. I subconsciously thought that Zhang Yingying had been reading in his bedroom for the past ten minutes.

But I didn't see it.

Zhang Yingying is Han Chunsheng's wife, if she took advantage of Han Chunsheng washing the dishes to mess things up in the study, Han Chunsheng won't notice, and I won't know.

Even if there had been people staring at the study from the south, Zhang Yingying could have just pulled the curtains and turned off the lights after she entered the room, before leaving after she had worked on the wall. After all, she was the hostess of her family.

And this process, if you move quickly, should be done in a minute or two?

Taking a step back, even if she did something, Han Chun Sheng would put down the dishes he was washing and return to the study room. Zhang Yingying could also say that she had entered the room to look for a book and had done nothing.

Furthermore, from the way Han Chun Sheng cleaned up the dishes after their meal, it could be seen that the rules of their lives were clearly divided. Zhang Yingying cooked while Han Chunsheng washed the dishes.

In that case, Zhang Yingying must be very clear about the amount of time Han Chunsheng spent washing the dishes, as well as the amount of time Han Chunsheng spent washing the dishes.

Perhaps people like Han Chunsheng would be very dedicated to everything they did …

Zhang Yingying's illogical calmness, her understanding of Han Chunsheng, her status as the mistress of the family, and so on all hinted that there might be a problem with Zhang Yingying.

Thinking about this, I finally understood why Li Fengyun kept staring at Zhang Yingying.

He slapped his forehead and felt that he was too stupid.

Xu Haoqing and Li Fengyun didn't personally see what happened here, but from my narration and my observations of Zhang Yingying, they could tell that something was amiss. As a witness, I wasn't sensitive enough.

Indeed, it couldn't compare to three years ago.

Three years ago, I wouldn't have made such a mistake, right?

As if he had felt my depression, Li Fengyun put down his binoculars and lightly patted me on the shoulder, "Third brother, don't let your thoughts run wild. My guess and Captain Xu's guess may not be accurate. Let's each express our opinions and research on it …"

I nodded, thinking about Zhang Yingying and Han Chunsheng.

"Captain Xu, what did you call Zhang Yingying over to the other room to talk about?" Li Fengyun asked.

Xu Haoqing: "I asked her if Han Chun Sheng had a mental illness. He looked more like a paranoid patient, but after combing through, I felt that Han Chun Sheng was not being murdered, but was actually being targeted. "Tell me, is it possible …"

"After eating those meals, his body either secreted or produced some substance that could be used on his eyes or his optic nerve. Then, while he was washing the dishes, Zhang Yingying went to the study and wrote something on the wall that would frighten Han Chunsheng, of course, ordinary people wouldn't be able to see it. When Han Chunsheng returned to the study, perhaps he didn't pay attention to the words on the wall at that time, or maybe that thing didn't have full effect at that time, so he didn't show any abnormalities. It wasn't until nine o'clock when he hung up, rang the bell, looked at him, and found that the writing on the wall was extremely frightening to him." When we got there, the effect of the substance lessened. From his point of view, the words on the wall gradually disappeared, so the guilty Han Chunsheng thought that he might have seen wrongly and chased us away? "

After Xu Haoqing finished his analysis, he looked at Li Fengyun and me in anticipation.

What he was saying was not impossible, but it was too inconceivable.

Was there really such a magical substance?

As the elders said, after one's eyes are smeared with black dog blood or cow tears, one can see dirty things?

A bit mystical …

Li Fengyun also disagreed, he scratched his disheveled hair, "Captain Xu, what you're saying is very strange …"

"What's strange?"

"I can't say. I remember that Zhang Yingying studied architecture, not biochemistry, right?"

Xu Haoqing: "Maybe I taught myself later …"

"Self-taught biochemistry can achieve such a level and effect? I don't agree. "

Both of us disagreed with Xu Haoqing's conjecture. Xu Haoqing spread out his hands, "Then tell me, what happened? Why is it that only Han Chunsheng can see the words on the wall?"

Nonsense, this was the crux of the problem. If he could understand this point, then Han Chun Sheng's matter would be easily resolved.
