"So, Professor, what is the most important reason?"

"Now, you see, it's been more than a year since D committed the first crime, if this is D's birthday, these people won't have only this one action, at least twice, right? But why is it only this time that these people can be so motivated to celebrate his birthday? So, the reason why these people left this sentence should not be because, or not just because it was D's birthday, I think, more because, that day was a very important day for D, similar to ...... Rebirth from the fire and the like......"

"However, according to the previous inference, D should be a boy, isn't it a bit inappropriate to use this word?" Before others could refute their opinions, Ji Ning first raised doubts, Ji Ning frowned, not knowing what to say, but D's gender had become blurred in his mind, and he thought, perhaps, should he abandon D's gender now, and then see, is there anyone who matches the portrait in his heart......

"Professor, which case should we start investigating, Professor?" Lin Ruoyun had to give Ji Ning an affirmative answer, when she didn't know the existence of those people in her kingdom, she could deduce this, it was really powerful.

"Huh?" Ji Ning came back from his contemplation, looked at Lin Ruoyun, and unconsciously compared D's portrait with Lin Ruoyun in his mind: a year ago, there was a sudden accident at home, and a very important person was killed; he came to Jiang City from City A for some special reasons around September; when Fang Yu killed someone, D must have appeared nearby; and in the days when Lin Xiangshen held a press conference, a special thing happened to D......

After comparison, Ji Ning was a little horrified to find that if you ignore factors such as gender and age, Lin Ruoyun is almost exactly the same as that portrait......

How could this be? When he realized his intentions, someone actually told him that the D he had been looking for was Lin Ruoyun he liked? Maybe he felt wrong, according to Fang Yu's portrait, that person was obviously Ji Wen, yes, it wasn't Lin Ruoyun, D was a man.

"What's the matter, Ruoruo, what were you talking about?"

"I mean, you say, we should start with that case?"

Look at me, where do you think, if you care so much about the development of the case, what's going on D, if it's D, she shouldn't care so much about starting with that case, who would think so much about letting the police arrest her?

"If it were me, I would start with the Hutong heart-digging case, after all, there were witnesses to that case. Ji Ning desperately shook off the strange thoughts in his mind and concentrated on answering the question raised by Lin Ruoyun: Judging from the portrait given by Fang Yu and the strange email that Ruoruo once said, Ruoruo should also be a victim, right?

"Wei Anyi, remember to ask the woman who reported the crime to come to the police station to make a record, Ji Han, then please hypnotize her to see if she can draw a portrait of the murderer. At the same time, Song Caiwen, you go and see if there are any people between the ages of 25 and 39 who have ever received harm in this regard. After finding a very reasonable excuse for Lin Ruoyun, Ji Ning returned to his previous indifferent expression.

Of course, these are all ignoring the smirk in the face of Lin Ruoyun......
