"Good morning!"

"Good morning, police department, why did you come so early today?" Miki came to the special search department early in the morning, and couldn't help but feel a little surprised when she saw Lin Xiuyi making coffee in the office with great interest.

"Come and try it, this is the black coffee I made by drip filter from the newly bought coffee pot, and I deliberately put a lot of effort into the grinding of the coffee and the mastery of the water temperature......" As soon as Lin Xiu saw Miki, he couldn't wait for her to come over and taste his latest coffee experiment. At this moment, a strong aroma filled the room of the special search department, and under Lin Xiuyi's patient preparation, the essence of the coffee powder was fully extracted.

"It's so fragrant!" Miki picked up her panda coffee cup, first took a deep sip of the aroma of coffee, and then took a gentle sip, the entrance was slightly bitter, and then the mouth was full of the smell of charcoal-fired coffee.

"Are you busy!" While the two of them were leisurely enjoying their first cup of coffee in the morning, Section Chief Matsuda, a regular visitor to the Special Search Department, also walked in.

"Section Chief, by the way, does the section leader have time, I want to ask you a few words?" Lin Xiuyi suddenly stopped Section Chief Matsuda, and then whispered to him. Section Chief Matsuda felt a little curious, so he followed Lin Xiuyi to the coffee machine. Seeing this, Miki returned to her workstation with interest.

"Section Leader, I would like to ask who I should go to if I want to buy Semtin in China?" Lin Xiuyi asked cautiously in a low voice.

"You're asking Shoji Kuroda about that batch of semtin?" asked Matsuda vigilantly.

"Yes, I want to know how Shoji Kuroda got those semtins, which have been strictly controlled explosives since the Tokyo subway bombing ten years ago, and now it's no less difficult to get them than drugs. Such a large number of Semtins, if it weren't for a gang with strong strength, would never have been able to do it......" Lin Shuichi explained the clues he had obtained from thinking last night to Section Chief Matsuda, who took a sip of coffee and then fell into deep thought.

"Why don't you go to the police for this kind of thing?" Section Chief Matsuda asked uncomfortably.

"Public security, actually, I think there are some problems with the police interrogation record, and they are likely to cover up something for me......" Lin Xiuyi shook his head helplessly, and then said with a sigh.

"If you ask that, I really have a few suspicions! Among the Vietnamese underworld organizations in RB, the most powerful is the Silver Dragon Society, which started by smuggling arms in the early years, but in the past few years, it seems to be ......slowly bleaching," Matsuda said after pondering and meditating.

"Can you let me talk to the people of the Silver Dragon Society, it's best to help me inquire about Semtin!" Lin Xiuyi asked Matsuda as Chief Matsuda.

"Well, well, but I can't promise you anything right now, I'll try to inquire first, and I'll let you know if there's any news!" replied Matsuda, the head of the section, and then turned around to leave the special search department.

"Thank you for your trouble!" Lin Xiuyi said respectfully.

After sending off Section Chief Matsuda, Lin Xiu called Miki to his side and explained a few words to her, and then Lin Xiuyi left the special search department alone.

……

In the afternoon of the same day, Lin Xiuyi received a call from Section Chief Matsuda, asking him to go to Café 1894 in the Mitsubishi No. 1 Museum Art Museum (a good place to talk about things in RB criminal investigation dramas) to meet with the people of the Silver Dragon Society.

Café 1894 is a famous Western restaurant in Tokyo, known for its authentic Western cuisine, but it is also famous for its afternoon tea. All kinds of pastries, coffee, and English black tea are widely acclaimed, but the price is naturally not affordable for ordinary people. When Lin Xiuyi arrived here, as soon as he entered the door, he saw Section Chief Matsuda sitting in the corner, and there was a person opposite Section Chief Matsuda with his back to Lin Xiuyi.

Lin Xiuyi walked quickly to his seat, and the waiter pulled out a chair for him, and then asked him what his preferences were!

"Please bring me a cup of lemon black tea!" Lin Xiuyi said without thinking.

"This police officer, don't you want to taste the coffee here, the raw materials are all imported from the place of origin......" Just as Lin Xiuyi looked at the third person in the seat with his eyes, the other party suddenly opened his mouth and recommended it.

"No, for me, the caffeine intake in the morning is enough for my needs for the day!" Lin Xiuyi politely refused.

……

After the drinks were all served, Section Chief Matsuda began to introduce Lin Shuichi and the strangers to each other.

"This one is my colleague, Lin Xiuyi Police Department, and this one is the eldest son of the previous president of the Silver Dragon Society, Ruan Xuan Fuzhong!"

"Speaking of which, Section Chief Matsuda is also my benefactor, so since it is Section Chief Matsuda who got rid of it, I naturally won't hide anything, if there is any problem, you can just ask!" Ruan Xuan Fuzhong said very happily.

"Since you said so, I'm not welcome, I won't hide it, I want to ask you which of the Vietnamese gangs in RB has the ability to import 30 tons of semtine explosives?" Lin Xiuyi lowered his voice and asked in a low voice.

"With all due respect, I don't think any Vietnamese gang can smuggle such a large amount of explosives! In fact, Director Matsuda now knows that gangs prefer industries such as drugs and pornography, which are less risky and more rewarding, and in addition, we will also get involved in some legal businesses, such as smuggling explosives, and those gangs with deep roots will probably not take this risk, and those smaller gangs basically do not have that ability......" Nguyen Xuan Fuzhong thought about Lin Xiuyi from the perspective of the gang.

"That's right, the explosives from the Tokyo subway bombing......"

"Those? Actually, I was very skeptical about the authenticity of the official announcement back then, smuggling explosives, such a dangerous thing was transported from Vietnam to RB thousands of miles away, do ordinary gangs have the ability to do this?

Listening to Ruan Xuan Fu's methodical analysis, Lin Xiuyi felt more and more that there were other problems in the investigation of the Tokyo subway bombing, first of all, the problem of explosives, if even those powerful gangs were afraid of danger and were unwilling to smuggle explosives, then where did Yoshii Yizhao buy the explosives used back then?

"So I would like to ask, if anyone is willing to pay a high price for Semtin, who should they go to?"

"That kind of thing doesn't need to be smuggled from Vietnam, in fact, there are sellers in RB, don't you know who those Semtin who stayed in Vietnam back then?" asked Ruan Xuan Fuzhong to Lin Xiuyi.

"Americans?" As soon as these words came out, Lin Xiuyi immediately broke out in a cold sweat.
