"Xiu Yijun, what specific thoughts do you have for the next search plan?"

After the day's work, Lin Shuichi was called to Roppongi's bar by Nagao Keiko to discuss the next work plan. Lin Xiuyi has not yet adapted to the sudden identity gap between him and Jingzi, so he seems very restrained. However, he more or less guessed that he was suddenly assigned to be in charge of the case of Shoji Kuroda, which should be because of Keiko Nagao.

"Why did you put me in charge of Shoji Kuroda's case?" asked Lin Shuichi plucking up the courage to ask Keiko Nagao.

Keiko took a sip of the margarita in front of her, and then asked the bartender for a copy of the same, which was fruity and popular with ladies, and the margarita of the bar that Keiko chose had her own unique recipe and was very famous in the Roppongi area.

"Xiuyi-kun, with all due respect, you and the Special Search Department have now been abandoned by the search lesson!" Jingzi turned his head to Lin Xiuyi and said extremely seriously.

"This ...... What does it have to do with me being in charge of Shoji Kuroda's case?" Lin Xiuyi couldn't help but feel a little embarrassed when Jingzi revealed his old secrets. But after thinking about it carefully, there seems to be nothing bad about the unit by the window, there is more money and less work to get off work early, what else can I ask for?

"Xiu Yijun is a bureaucrat from the elite group, and it stands to reason that he will be promoted to a police officer after three years, after all, he is an elite who has passed the national first-class civil service examination. Please rest assured, even if you continue to stay in the special search department, you will be promoted step by step at that time, because this is what the elite group civil servants deserve, but it is difficult to say whether you can continue to stay in the search department!" Keiko said as if she had come over.

Lin Xiuyi actually understands these things very well. As long as he doesn't make any major mistakes, he can still be promoted to the police officer without suspense after three years. This is because if a civil servant from an elite group cannot be promoted to the police station, it will greatly damage the credibility of the national first-class civil service examination. But after that, Lin Xiuyi may be transferred out of the search section and sent to a unit under the Metropolitan Police Department to take charge of some inconsequential matters until the day he retires. This kind of day may be interesting at first, but after a long time, it is as if you have been thrown into an abyss that will never see the exit, and there is no hope in sight. And this time, the opportunity brought by Jingzi may be Lin Xiuyi's hope to finally change his fate.

Lin Xiuyi had something in his heart, and left in advance after drinking a few glasses of wine, Jingzi still had work matters to deal with, and after everyone separated, Lin Xiuyi took a taxi back to his apartment alone.

Nothing to say all night......

The next morning, Lin Xiuyi and Miki rushed to the dock where the explosion occurred a few days ago to investigate the site, which had been completely sealed off by the Metropolitan Police Department, and the scene was a mess. Due to the large area of the explosion, the large amount of evidence left at the scene, and the fact that dozens of policemen died here, the forensic section, the mobile search team, and the scientific search and research institute all participated in the evidence collection at the scene.

"You've done a great job!"

Lin Shuichi and Miki wore the armband of the search lesson and walked into the blockade area with white gloves. Dozens of field technicians were searching for evidence at the same time in the cordoned off area. From time to time, a low-ranking police officer raised his hand to salute Lin Xiu, and Lin Xiu nodded in response.

"Ahh If it continues like this, I'm afraid that we won't be able to successfully end the search at the scene in a week!" Shinsuke Narita, the head of the mobile search team, walked to Lin Xiuyi's side, grabbed his hair and said distressedly.

"It doesn't matter, just tell us everything you've discovered!" Lin Xiuyi said politely to Narita.

"The bomb was supposed to have been planted in the trunk of a car, and we found some unreacted explosive components on a piece of automotive metal attachment. It was confirmed that it was indeed a Semtin 1A explosive, which contained a content of up to 70 percent PETN (pentaerythritol tetranitrate), which was the same type of explosive used in the Tokyo subway bombing 20 years ago......"

Lin Xiuyi couldn't understand the analysis report of the explosives at all, because it was difficult for ordinary people to get their hands on explosives of this level as Semtin, but he could find some clues from the subtle differences in the various components of the explosives. The content of various components of explosives produced in the same batch should be basically the same, even if it is the same formula, the explosives produced in different batches have subtle differences in some aspects.

PETN (pentaerythritol tetranitrate) is a more reactive explosive than TNT, so it is not usually used alone. Some other ingredients need to be added to blunt the reaction of the explosives. Therefore, in addition to PETN (pentaerythritol tetranitrate) and RDX (), some sealants, plasticizers, and antioxidants will be added to the semtin 1A explosive. The proportions and production processes of these ingredients are basically in the hands of explosives manufacturers and the military, and ordinary people have no access to them.

For those who have not mastered the formula, it is too dangerous to make semtine explosives. Therefore, the safest way is to buy semetin that has been produced on the market, among which semetin without the addition of explosive tracer is the most popular in the market. These dangerous things are often made by terrorists to easily evade security bombs.

Now that Lin Xiuyi has obtained the explosives as an analysis report, the next step is to find out the production batches of this batch of explosives to determine the true source of these explosives.

"What did you find in terms of the detonating device?" asked Shuichi Hayashi, while Miki took notes. There are only two people in the special search department now, so the specific work has to be handed over to the relevant departments to be responsible. Now that time is pressing, Lin Xiuyi is no longer allowed to continue waiting for the on-site investigation report, so using all the clues that have been found to carry out the search work in advance is Lin Xiuyi's only choice at present.

"The detonation device should have been modified from an ordinary mobile phone. Just call the corresponding phone number!" replied Shinsuke Narita without thinking.

"Oh, that means it's possible that Shoji Kuroda didn't appear here? he just needs to use the phone to remotely detonate?" Lin Xiuyi asked suspiciously.

"It's a possibility, but there were a lot of people who saw Kuroda walk into the warehouse, and after the explosion, Kuroda hacked into our communications system......" Shinsuke Narita explained to Hayashi.
