I have to say that the efficiency of the Metropolitan Police Department after the reform is still acceptable, especially for those things that are beneficial to the entire organization, the efficiency will be faster.

Tang Ze just finished talking about these things on Monday, and the event was held the following Wednesday.

Tang Ze also found a job for himself and became busy.

Tang Ze did not recognize many of the criminals who came to the meeting. The criminals from various prefectures that he was familiar with were basically gone. The only one who came from Gunma Prefecture was Yamamura So, whom he was familiar with.

But this is normal. After all, young criminals have a stronger ability to accept new things. On the contrary, old criminals are a little difficult to understand because of their age.

But they are the main force of the search in each county, and their experience and search ideas are also what young people need to continue to learn.

What Tang Ze has to do this time is to make up for their shortcomings as much as possible and let them understand how to use these weapons.

Obviously, the effect is quite good. After Tang Ze explained many cases that were solved by scientific research, many criminals were enlightened.

There were even two veteran criminals in two counties who got inspiration and used the scientific research tools to remotely control their subordinates and solve two cases directly.

As soon as this result appeared, the meeting became more lively.

To be honest, as a criminal, the first priority is to catch the criminal. The means don't matter.

The main reason why they did not use the tools in their hands and still used the old methods to solve the case was that they did not understand these things.

Although they know how to use machines like lie detectors, they don't understand more advanced things.

For example, they didn't even know that it was possible to test certain substances or even identify multiple fingerprints in the same place.

If you don't understand it, you naturally can't use it, and the researchers at the Science and Technology Research Institute don't participate much in case investigations, so naturally they can't give any advice.

It's as if there's a barrier between the two sides, just like gears that can't fit together and are stuck together, so naturally they can't perform efficiently.

Tang Ze's explanation was to bring the two sides closer together and let these criminals understand that although these people from the scientific research institute are researchers and not professional investigators, they can provide them with search suggestions from a scientific perspective.

This will change the mindset of criminals and allow technical personnel in scientific research to participate more deeply in the case, rather than passively waiting for work to be assigned like the original forensic department.

The meeting ended on Friday morning, which was a small benefit. After all, if you are not in a hurry to go back, you can stay in Tokyo for two and a half days before leaving.

As for Tang Ze, he naturally planned to take a break after he was busy.

After all, this exchange meeting was basically initiated by him, and he was the one who was concerned about it during the meeting.

Although it seems that he is just looking for something to do, Tang Ze actually gained a lot in the hidden gains.

First of all, it was he who proposed to establish the Scientific Research Institute. If it only functions in Tokyo, other places will feel that this initiative is not suitable for the local conditions, and it will naturally fail over time.

This meeting solved these problems. When the county leaders see the results, they will naturally pay attention to it.

In this way, Tang Ze's influence in various places will also increase invisibly. After all, Tokyo is the headquarters of the Scientific Research Institute, and he is the general manager.

In addition, this can also be regarded as Tang Ze's political achievement. Although he does not care about these, this is also a real capital for promotion.

After being lazy all afternoon on Friday, Tang Ze was originally planning whether to stay at home and rest for a while on Saturday and Sunday.

But the tree wants to be still but the wind does not stop. In the evening, as soon as Tang Ze got home, he received a call from Hattori Heiji, saying that there was a case to be handled in Tokyo and asked him to meet at the Mouri Kogoro Detective Agency on Saturday.

Upon learning that Hattori Heiji was coming to Tokyo, Karasawa naturally asked about the details of the case with great concern.

After learning that the case had occurred, Tang Ze roughly understood the circumstances of the case and did not ask any further questions.

After all, the case has already happened, so there is no need to prevent it. Let's listen to the details of the case tomorrow and then go to the crime scene to solve it.

And whether it is a murder case is actually still somewhat doubtful.

The next day, after washing up, Karasawa said goodbye to Ayako who was resting at home, and went to meet Kogoro Mori, Heiji Hattori and others.

There was no other way. Even if it was a case that had already happened, since it had not been solved and was still in Tokyo, whether for the reward or for the face of the Metropolitan Police Department, Tang Ze had to go even if he knew about it.

I drove to the Mori Detective Agency and chatted with the Mori father and daughter and Conan for a while. Soon, Hattori Heiji and the other two came.

That’s right, this time they were not only him and Kazuha, but also Detective Otaki from the Osaka Police Station.

The reason why this case happened in Tokyo and is related to Osaka is because the witness of this murder case is Detective Otaki.

This case was named by Hattori Heiji as the "locked room murder case that cannot be touched by hands or feet."

The deceased was murdered at some point while under criminal surveillance.

"Yes, last month, a man in his seventies died at home in an apartment in Haido-cho."

Sitting on the sofa in the office, Otaki looked at everyone and began to narrate: "The deceased's name was Kanzuki Hideri, and she was a high school teacher before she retired.

Among the students he taught was a man named Hito Kiriya."

"Aitō Kiriya?" After hearing the name, Maori Kogoro touched his chin and pondered.
