In an ordinary hut, an extremely well-dressed woman lies in the bathtub with a deep guilt on her face, and a few words are written on the wall: I am guilty, I deserve to die......

Ji Ning and the others just took a look here, and then went back to the police station. In fact, they came here just to let Ji Ning have better contact with the scene, so as to make a more appropriate psychological portrait.

In the police station, Ji Ning silently looked at the photos of various scenes posted on the whiteboard: in the first scene, the man was lime-painted with the word "happy", and he cared about the three scenes, and there was an envelope at the end of the silver thread, and the word "birthday" was written in the letter. From these two scenes, it seems that if this is a team crime, the other two will also leave something at the scene, but where?

Ji Ning's gaze kept moving on these photos, and he always felt that the Hutong Murder Case and the Hut Murder Case also had some hints like the other two cases, otherwise it would be difficult to explain some of the things that happened in them.

This is......

Ji Ning's gaze stayed on one of the photos, his pupils dilated slightly, he rushed forward, picked up the photo, and looked at the several men lying in the alley on it: No wonder I thought the shape of these people was so strange at the time, it turned out to be like this.

If that's the case, then the person who committed suicide in his own home probably had a similar effect.

However, in this case, where is the hint of the woman who committed suicide in her own home? Is it as bold and subtle as in the alley, or does it need to change something like in the museum to get this hint?

If I were this murderer—

I went to this woman's house, maybe I didn't enter her house, but somehow got in touch with this woman, and then controlled her, made her kill herself, and then I wrote those words on the wall, but how can I leave the message I want to leave here? Ah, here, this is where I can leave my message, so that D can see it, and it won't be known to those stupid cops!

Ji Ning opened his eyes and looked at the photo on the whiteboard, in the photo, the woman was lying in a pool of blood, and there were big subtitles on the wall: I am guilty, I deserve to die......

"Professor Ji Ning, what are you looking at here?" When Ji Ning was looking seriously, Lin Ruoyun patted him on the shoulder from behind and asked with a smile.

"Are you here?" Ji Ning was not as bored as he was at the beginning because he had just seen the commonalities of these four cases, and because his beloved came forward to talk to him, Ji Ning said that he was very happy, "I am looking at the commonalities of the deaths in these four cases." ”

"So, do you see that?"

"Of course. Ji Ning put his hands behind his back, pretended to be profound, and sold a pass, looked at Lin Ruoyun, and said with a smile: "Do you want to know?"

"Hmm. Lin Ruoyun nodded seriously and said, hiding the doubts and horrors in his heart: Can this man really know the meaning of their actions?

From the very beginning, from the moment she saw the second case, Lin Ruoyun had a guess, guessing that this might be a good thing done by those people, and also guessed their intentions to do these things, but she didn't expect that Ji Ning could know the intentions of several of them so quickly......
