At half past ten o'clock in the evening, in the temporary office of the Yaoming City Special Investigation Group, Zhao Yuzheng was talking to Miao Ying on the phone with a proud face:

"What's going on, meow meow?

"You know what? When I told the doctors in the psychiatric hospital about what Liu Cheng said to me, the doctors were stupid!

"In their eyes, it was simply an impossible task, and my deeds even enlightened them......"

"Okay, you," Miao Ying disagreed, "You're just a blind cat and a dead mouse, if it weren't for your bad habits, how would you know that Liu Cheng has been focusing on stones instead of flowers?"

"Hey, you're still not convinced, are you?" Zhao Yu said, "10 days! 10 days! If you were an ordinary person, you would have been crazy with you! You just praise me, baby......"

"Hey, it's still ...... if you're coquettish," Miao Ying smiled, "Okay, I have to say, if it were me, I would definitely not have your perseverance! You are a fool and a fool, no matter how unreliable things are, miracles can always happen to you!"

"Hmm...... You don't seem to be praising me when you say this!" Zhao Yu was not satisfied.

"Okay, let's get down to business!" Miao Ying returned to seriousness, "Since it has now been proved that the murderer of the sanatorium murder case is not that Nong Zhifa, then this matter really needs to be investigated!"

"It seems that your original hunch was right!"

"Well......" Zhao Yu said, "Before I went to the mental hospital, I watched all the confession videos about Nong Zhifa, and I always felt that this person was very problematic!"

"Oh, what's the problem?" Miao Ying asked hurriedly.

"Actually, the reason why I want to stay in a mental hospital for so long is not entirely for Liu Cheng," Zhao Yu finally revealed his true intentions, "Actually, I want to feel the world of the mentally ill, experience it well, and then ......make a comparison with Liu Cheng."

"Ah, won't you......" In an instant, Miao Ying was startled, "Zhao Yu, you don't want to say that Nong Zhifa is also a mentally ill person......, right? This is also ......"

"That's right," Zhao Yu nodded, "You still know me best, from the moment I saw the video, I felt that Nong Zhifa's spirit was abnormal!"

"Now, after my experience from a psychiatric hospital, I'm even more sure of this speculation!

"Nong Zhifa's eyes, demeanor, and numb expression when he spoke are exactly the same as those mentally ill, and they can't be pretended to be at all! I suspect that Nong Zhifa is likely to have paranoia!"

"Delusional?" Miao Ying was surprised, "I ...... I've also seen the video, but ......"

"That's right," Zhao Yu said, "It is precisely because of Nong Zhifa's melancholy eyes that it is easy for normal people to naturally have an illusion after reading it, thinking that this person is very similar to those psychologically unbalanced perverted murderers!"

So, most likely, from the very beginning, we fell into the established stereotypes and fixed this person!

"But what if...... He's just a paranoid patient?"

"This ......," Miao Ying gasped, "This is also terrible......, isn't it? So...... The real murderer...... Who could it be? Surely ...... Someone who is very familiar with Nong Zhifa, right?"

"Anyway, all this is just my personal speculation," Zhao Yu said, "I plan to go to the prison where Nong Zhifa is located next, and ask the people there to see if I can get any clues?"

"Me...... Tsk......"

"What's wrong?" Miao Ying was familiar with Zhao Yu's routine, and instantly heard the question, and hurriedly asked, "Have you already thought of something?"

"Well...... Zhao Yu said, "I don't want to show my bottom until the critical moment......"

"Don't sell it with me, okay?" Miao Ying urged eagerly, "My big detective, good detective, tell me quickly, I can help you think of ideas!"

"Well, okay!" After thinking about it, Zhao Yu said, "I suspect that the key point of the memoir murder record is likely to be in prison!"

"Oh?" Miao Ying asked, "You mean, the real murderer is also the prisoner in that prison?"

"No!" Zhao Yu said affirmatively, "I feel that the real murderer is not the prisoner inside, but the prison guard!!"

It's really shocking, Zhao Yu said a word, and Miao Ying on the other end of the phone was instantly stunned.

After slowing down for more than ten seconds, Miao Ying woke up from the shock and said in a trembling voice: "What do you mean...... There are prison guards...... What is it that makes Nong Zhifa confess his guilt...... Why?"

"I don't know," Zhao Yu said bluntly, "I just think that the real murderer knows the police's methods of handling cases, and it is very likely that he is someone inside the police system!"

"Also, according to prison records," Zhao Yu said, "Nong Zhifa is a lonely person and has no regular cellmates, so only the prison guards are more convenient to contact him!"

Moreover, only the prison guards know more about Nong Zhifa and know that he is the best candidate......

"And ...... From a class standpoint, prison guards are a kind of strength to prisoners, and it may be easier to implement psychological cues!"

"Psychological suggestion...... Miao Ying said in surprise, "My God! Do you think that there was a prison guard who saw that Nong Zhifa had paranoia, so he implemented psychological suggestion to make Nong Zhifa think that he was a serial killer, so that he could recognize the charges in the murder memoir?"

"Is that ...... It's a little outrageous, isn't it?"

"There is indeed this kind of scene in the movie, and I haven't studied it carefully yet," Zhao Yu said frankly, "So, I'm going to discuss it with Wu Xiumin when I go back and see if there is such a possibility?"

"Meow, look ......" Zhao Yu spread out his palm and analyzed, "Assuming my previous guess was right, Nong Zhifa is a mentally ill person, then...... Why is there never a record or report on the report given by the prison authorities?

"And ......," Zhao Yu said again, "I have read the prison interrogation report, and the testimony of those nong zhifa's cellmates is also vague and evasive, and it seems that ...... It's like you're afraid of something......

"Therefore, I think there is probably something wrong with the prison, and this cat is likely to be the key to solving the case!"

"You...... Well......" Miao Ying thought for a long time and said, "It sounds like you are indeed very reasonable, but you seem to have overlooked an important issue!"

"What's the problem?" Zhao Yu asked.

"Is the murderer full of food?" Miao Ying also bluntly expressed her suspicions, "The murderer is obviously at large, and no one knows about the murder memoirs, so ...... Why would he take such a risk to induce a prisoner?

"It will increase his chances of exposure, and if he is a prison guard, then it is even more unreasonable, right?"

"Well, indeed!" Zhao Yu admitted, "I have indeed considered this before, and I think that there should be two possibilities for the real murderer to do this."

"First, he is old, maybe he has a terminal illness or something, he doesn't want the case he committed to be forgotten like that, so he wants to express his desire under the pretense of Nong Zhifa.

"It's like some kind of perverted show-off!

"Second, I don't know what happened, so that the murderer thought that his crime was about to be exposed, and he was anxious to find a scapegoat, so he chose Nong Zhifa!"

"Tut-tut......" Miao Ying smacked her lips and said, "I still don't agree with your speculation! I always think that psychological suggestion is too detached from reality, and the chance of success is not at all."

"Nong Zhifa is still an important suspect in the murder memoir!

"It's just that some cases are not his doing, maybe ...... He also has an accomplice, or...... It's something else!"

"Okay then," Zhao Yu said, "Actually, I also hope that I was wrong, but ...... I still think that Nong Zhifa does not meet the basic characteristics of a murderer at all......

"So, let's wait until I go to the prison to investigate and come back, and then let's continue the discussion......"
