By the time everyone left the victim Kaoru Ishii's house, it was already close to the end of work, and Lin Xiuyi suggested that everyone find a tavern to have a good drink, after all, it was a fortunate thing to have a lovely woman in the group.

"How about we go eat charcoal barbecue meat, don't be polite to me, even if it's for Miki's welcome dinner!" Lin Xiuyi greeted everyone, and his subordinates naturally would not object. Anyway, today's work ended early. The evening is just the right time to relax.

So everyone got in a car and went back to the Metropolitan Police Department to return the car, and then took a taxi to Akasaka. This generation is the closest place to consume in the RB political core, surrounded by high-rise buildings and frighteningly high housing prices. There are plenty of hotels, fine restaurants, and other entertainment venues. Lin Xiuyi chose to entertain the new subordinates here, which can fully show the importance of his subordinates, of course, the cost is naturally expensive. Lin Xiuyi chose a charcoal barbecue restaurant with high praise, so that everyone could not only get acquainted with each other, but also discuss the next step of the case by the way.

"Miki, do you want to drink beer?" Lin Xiuyi and the others all ordered beer, but I don't know if Miki can drink it, the first time I eat with someone, it's better to ask on purpose!

"Police, actually, I can't drink!" Miki said with a look of embarrassment.

"Shop, are there any drinks that girls can drink?" Lin Xiuyi took the initiative to ask the clerk.

"How about the highball wine, although there is whiskey in the raw materials, but it is diluted with soda, and the taste is very light, which is perfect for girls?" replied the waiter without thinking.

Lin Xiuyi turned his head to look at Miki, Miki nodded happily, and gave Lin Xiuyi a sweet smile in return.

It didn't take long for the two large plates of very characteristic barbecue platter to be served by the waiter, and the various parts of the meat on the plate were cut into thin slices by delicate knife skills and neatly placed on the white tableware, and the beef was the best frosted beef, and the bright red meat was dotted with uniform white fat. It looks like you've had an appetite.

"The sauce is specially made at our restaurant, so you don't need to roast the beef too much, as long as the oil is on top and you can eat it, please enjoy it!" said the waiter after explaining how to eat it. Everyone raised their glasses and toasted happily.

"Ah...... Ha, it's really comfortable to have a drink after work!" Lin Xiu drank them one by one, and after the cold beer was swallowed, he felt that the fatigue of the day was swept away.

"Police, can I ask you a question?" After Miki put down her wine glass, she suddenly asked Lin Xiuyi.

"Of course you can!Miki, you behaved very well today, it's not easy to communicate with those children!" Lin Xiuyi replied with a smile.

"Police Department, judging from our confession of Kaoru Ishii's re-investigation today, although there are discrepancies in some places, most of the content is similar to the original record, am I disappointing you?" Miki asked with a frustrated expression, although she had just come into contact with this case, but because the facts of a case were not complicated, Miki looked at it in the car. She had hoped that she would be able to ask for something new from Kaoru Ishii today, but except for some differences in time and details from the last time, Kaoru Ishii's account of the incident was almost exactly the same as what was recorded in the transcript. This made Miki not frustrated.

"How could you disappoint me?" Lin Xiuyi asked with a smile.

"Police Department, so you have found a new clue?" Hearing Lin Xiuyi say this, Hanagaku suddenly came to his senses, and Aizawa, who was silent on the side, also raised his head and looked at Lin Xiuyi.

"I don't know if you've noticed, that Kaoru Ishii doesn't seem to be afraid of the suspect who harassed him!" Lin Xiuyi reminded everyone.

"Ahh

"That's right, that little girl seemed to be quite excited when she spoke, thinking that she had scared the suspect away!"

"Police, what do you mean......" Aizawa didn't quite understand what the little girl's unusual behavior could mean, and hurriedly asked.

"You've heard of Lokar's law of material exchange, as long as the perpetrator commits a crime, he will inevitably act directly or indirectly on the violated object and its surrounding environment at the crime scene, and will consciously or unconsciously leave traces!" Lin Xiuyi reminded.

"But shouldn't we go to the crime scene to see if there are any traces?, why should we go to the victim and record a confession again?" Miki asked, still puzzled.

"The traces of crime I am talking about do not only include material traces such as fingerprints and footprints, but also the impression of the offender that remains in the victim's mind is also an important trace of crime!" Lin Xiuyi explained to everyone.

"Police, I've studied Lokar's law of material exchange, but this is the first time I've heard of yours. But in the case of the victim Kaoru Ishii, this statement is indeed very reasonable!" Aizawa, who had not spoken all this time, suddenly said.

"I've also heard of this law of material exchange in Lokar, but it's also the first time I've heard of your statement that criminal impressions are traces!" Miki Nakayama nodded in agreement when she heard Aizawa's words.

"Forget it, let's not talk about it! Although we cannot allow the victim to look directly at the photographs of the deceased, we can confirm whether the cases were committed by one person based on the victim's impression of the perpetrator. Even if this cannot be directly used as evidence to close the case, it can at least allow us to grasp the direction of the investigation of the continuous indecency case, whether it is really a single person who committed a continuous crime!" Lin Xiuyi did not dwell too much on the issue of the different interpretations of Lokar's law of material exchange. Because this is not an academic discussion of criminology, but a concrete analysis of the case. In fact, what Lin Xiuyi didn't know was that the inclusion of the spiritual traces of crime in Lokar's law of material exchange was actually a Soviet criminological theory. Chinese criminological theories were studied in the Soviet Union, while RB was taught in the United States. It is difficult to say which of the two different systems of crime theory is better, but for now, the Soviet explanation is clearly superior.

"By the way, Aizawa, you will take Miki to continue visiting the victim tomorrow to see if there are any occasional victims who have the same impression of the perpetrator as Kaoru Ishii!Hanagata, tomorrow I will go around the area where the fourth case occurred and see what new discoveries can be made!" Lin Xiuyi commanded.
