After an hour...

As more and more police officers were notified and rushed to the Metropolitan Police Department, more and more police officers participated in the search for Kuroda Shoji's trace.

The difficulty of finding a five-kilogram bomb in the complex Tokyo subway system within 24 hours can be imagined. The only clue so far is the phone call challenging the police. But what Lin Xiuyi cares about is not these, but the real purpose behind Kuroda Akio.

Now that Akio Kuroda has regained his freedom, shouldn't he leave the RB immediately? Instead, he is risking his life to import 30 tons of semtine from abroad. What exactly does Akio Kuroda want to do, he thinks Lin Xiuyi was very curious about what to get.

"The police department, there is a call for you, it seems to be from the Public Security Committee!" Miki suddenly came to Lin Xiuyi, interrupting Lin Xiuyi's thoughts. Lin Xiuyi finally woke up, then picked up the extension phone on his desk.

"Shuichi-kun, I heard that Akio Kuroda appeared and planted a bomb in Tokyo's subway system?" Keiko asked worriedly on the other side of the phone.

"I don't want to lie to you, the situation is indeed like this. Akio Kuroda has given us twenty-four hours. There are still more than twenty hours left, and we are going all out to search for the trace of the bomb!" Lin Xiu was truthful told Jingzi the situation.

"Xiuichi-kun, please resolve this crisis as soon as possible, otherwise, it will bring great trouble to Ando-sensei," Jingzi said to Lin Xiuyi in a commanding tone on the other side of the phone.

"This, I'm sorry, I can't make such a guarantee, unless from now on, the operation of all Tokyo subway lines will be suspended, giving us enough time to conduct a thorough investigation of the Tokyo subway system!" Lin Xiuyi said helplessly.

"This is impossible at all, listen to Xiuichi-kun, you, me, and Ando-sensei are now partners sitting on the same boat. Once you are in charge of the investigation of the Kuroda Shoji case, there is a serious negligence, not only you If you have to stand up and take responsibility, Ando-sensei will also be implicated. Remember, no matter what, there can never be another serious incident like the Tokyo subway bombing..."

Lin Xiuyi and Jing Zi discussed for more than ten minutes. Jing Zi's meaning was very clear. Lin Xiuyi must calm down the incident as soon as possible without any help from the top. After Lin Xiuyi put down the phone, he fell down on the seat, rubbed his forehead with his hand and fell into deep thought.

As the detective in charge of this case, Lin Xiu has a very detailed understanding of Kuroda Akio's resume. Kuroda specifically mentioned the time span of 24 hours, what exactly does that mean. Why is it twenty-four hours, Lin Xiuyi is very puzzled.

Twelve hours, if you really want to do things, this time is too long, and twenty-four hours later, it will be around one o'clock in the morning, when only a few subway lines are still in operation. So to say……

"Well, who knew that the subway line was still in operation after 12 midnight?" Lin Xiuyi suddenly stood up and asked loudly to everyone.

Almost everyone stopped their work and looked at Lin Xiuyi. The entire office area suddenly became very quiet.

"That, sir, it's the Yurakucho Line! There will be the last train at about 12 o'clock in the morning!" A police officer immediately stood up and reported to Lin Xiuyi.

"Immediately contact Tokyo Metro Co., Ltd. and Toei Subway Co., Ltd. and ask them about all the subway lines that are still operating at one o'clock in the morning." Lin Xiu immediately ordered.

Lin Xiuyi suddenly understood a problem. The punctuality of RB's traffic system is the best in the world. Maybe Akio Kuroda intends to take advantage of this? After all, the purpose of detonating a bomb at one o'clock in the morning is definitely not to pursue maximum casualties, but perhaps for some other purpose.

Ten minutes later, the two subway companies in the capital gathered the relevant subway schedules to the Metropolitan Police Department according to Lin Xiuyi's request. In Tokyo, the last train of almost every subway train is scheduled in the early hours of the morning. From 12 midnight, the last train will depart from both sides of the subway line.

Since one o'clock in the morning was chosen, the line must be long enough, and the journey time should be more than an hour, so the shorter circular line recorded by the operation in the city was quickly excluded.

If you consider this way of thinking, then the three lines with the longest distances, the Tozai Line (30km), the Yurakucho Line (28km), and the Oedo Line (27km), are the subway lines that are most likely to be attacked.

Of these three lines, the Oedo Line is a circular line centered on the center of the city~lightnovelpub.net~ Most of the stops are located far from the center of Tokyo, and it seems that it does not make sense to attack this line.

As for the longest east-west line, the section closest to the city center is RB Bridge, Take Bridge, Otemachi, and Kudanxia four stations. It is close to the northeast of the Imperial Palace, surrounded by commercial areas. But what's the point of raiding an empty business district at one o'clock in the morning?

And the last remaining subway line is the Yurakucho Line that Lin Xiuyi takes every day. This route goes through Nagata Town and Sakurada Gate. Among them, Yongle Town is the seat of the RB Prime Minister's official residence. The Sakurada Gate is the seat of the Metropolitan Police Department and the National Police Agency, and the Ministry of Justice is just across the street. If you think about the problem from Kuroda's point of view, perhaps the Ministry of Justice, which sent him to prison and sentenced him to death, is the best target for revenge.

"Who can tell me where the last two trains on the Yurakucho Line will be at around one o'clock in the morning?"

As soon as Lin Shuichi's question came out, the police present immediately opened the navigation software on their mobile phones and started inquiries from Shinkiba Station and Wako City Station at the north and south ends of the Yurakucho Line.

"Report, the line from the south to the north will probably go to the place north of the Kochihara Station at one o'clock!"

"Report, the train heading south from Wako City Station will be in the area near Nagata Town and Sakurada Gate at one o'clock!"

As soon as these words came out, there was an uproar at the scene. There was no need for Lin Xiuyi to say anything, and everyone understood the problem.

Immediately notify Tokyo Metro Co., Ltd., and from now on, pay close attention to the passenger flow of Nagatacho Station and Sakurada Gate Station. See if you can find Akio Kuroda's figure in the video,

"Haha!"
