"All the possessions will be left to my wife, and I will dedicate my life to the vast snowfields of Hokkaido, and I don't have to worry about my whereabouts, so be it—— Yasuo Hashimoto"

Lin Xiuyi gently scribbled the letterhead with a pencil, and under the illumination of the light, the indentations written on the paper were immediately revealed.

"What is this, suicide note?" Kono Shohei sat in the tea room of Lin Xiu's box, and said in surprise in a low voice.

"It looks like this!" Lin Xiuyi put down the letterhead, and then carefully clipped it into his notebook. The contents of this piece of paper convey important information, so that even the paper becomes important evidence.

"If it's a suicide note, it's okay to say it more or less if you don't go out all night!" Shohei Kono asked Lin Xiuichi.

"Then we also have to look at the reason for his suicide, if he chose to kill himself because he killed Ms. Erika Shiraishi, Yasuo Hashimoto's suspicion still can't be ruled out!" Lin Xiuyi sighed silently in his heart, and then got up and walked towards the door.

"Where are you going?" Shohei Kono hurriedly asked when he saw Lin Xiu together.

"There is one last suspect left, Mr. Heizo Ishibashi, who lives in car nine, and I'm going to visit him now!" Lin Xiu said as soon as he turned to Shohei Kono.

"Wait a minute, I'll go with you!" Kono Shohei hurriedly got up and chased after Lin Xiuyi.

"Kono-kun, this is your purpose!" Lin Xiuyi suddenly said to Kono Shohei with a smile on his face.

"Purpose, what purpose?" asked Kono, puzzled.

"Approaching my purpose, maybe Kono-kun came over to say hello last night because he mistakenly thought I was a friend of Mr. Heizo Ishihashi!" Lin Xiuyi said directly.

"Is this ...... Sometimes...... The policeman's observation is really amazing!" Kono was suddenly recognized by Lin Xiuyi's true thoughts in his heart, and he couldn't help but feel a little embarrassed, he laughed dryly a few times, trying to resolve this embarrassment.

"So, Kono-kun should know some information about Mr. Heizo Ishibashi, I wonder if you would like to provide it to me, the policeman?" Lin Xiuyi stopped going around in circles with Kono, and simply made a direct request.

Kono Shohei lowered his head, thought about it seriously for a long time, and then finally said to Lin Xiuyi:

"It seems that I can't hide it from you, but it is rumored that Senior Minister Heizo Ishibashi of JR East will be appointed as the Minister of Economic Affairs of the Ministry of Foreign Affairs and participate in the Shinkansen cooperation program between the Ministry of Foreign Affairs and India. So......" Shohei Kono whispered to Shuichi Hayashi.

Lin Xiuyi immediately understood Kono's true purpose, it turned out that Kono ran to the Senhoua train for this, no wonder! This kind of thing is worthless to Lin Xiuyi, a bureaucrat in the police system, but for a Ministry of Foreign Affairs bureaucrat like Kono, it is an opportunity to actively fight for it no matter what.

"Xiu Yijun, if you can help me this time, I will remember this favor deeply!" said Kono Shohei pleadingly.

Lin Xiuyi was silent for a while, and then replied to Kono Shohei: "As long as you don't violate the requirements I made, as for other things, I won't interfere too much!"

Although Lin Xiuyi didn't agree explicitly, Kono Shohei still understood what he meant, an excited smile appeared on the corner of his mouth, and then followed closely behind Lin Xiuyi and walked towards the No. 9 carriage together.

"May I ask what Mr. Ishibashi is doing now?" Lin Xiuyi came to the door of the ninth carriage and asked the train staff standing at the door.

"Mr. Ishibashi has already informed us, if you come, I can take you in directly, but this gentleman is ......" The train staff couldn't help but ask with some confusion when they saw Kono Shohei behind Lin Xiu.

"This is my fellow traveler, Kono-kun from the Ministry of Foreign Affairs, can we go in together?" Lin Xiuyi said with a calm expression.

"Ah, I'm sorry, it's me who is too talkative!" The train staff no longer asked Kono's identity, he turned around and opened the door of car 9 for Lin Xiuyi and Kono, and then bowed down to Lin Xiuyi and Kono, and let the two into the box.

When Lin Xiuyi stepped into the No. 9 box for the first time, he also had to marvel at the imagination of the designer. There is a luxury that is not lost, ah no, is beyond the top suites of a five-star hotel. Not to mention that the carpet is a high-end foreign product, even the walls around the carriage are wrapped in silk, because it is located at the rear of the train, so the rear of the train has completely become the exclusive observation deck of the No. 9 car, Lin Xiuyi really wants to experience what it is like to live here.

"I heard that there was a terrible criminal case on the train, and now you are investigating, right?" Ishibashi Heizo saw Lin Shuichi and Kono Shohei who entered the door, and immediately couldn't wait to ask about the case.

"Hey, but if there is no result by the time the train arrives in Aomori City, I plan to transfer the case to the Aomori Prefectural Police Headquarters!" replied Hayashi Shuyi to Ishihashi Heizo.

"If, I'm asking you, if I ask you to find the real prisoner before the train arrives in Aomori, can you do it?" Ishibashi Heizo suddenly stood up, walked in front of Lin Shuichi, and asked in a serious and low tone.

"I'm sorry, this kind of thing can't be guaranteed!" Lin Xiuyi replied without hesitation. The work of solving cases sometimes depends on luck, and bold assumptions and careful verification are the guiding ideology for handling cases. But sometimes, even the right path suffers setbacks, so whether to continue the quest or go back to the beginning and start over is always the hardest choice. Even Lin Xiuyi, who has been handling cases for many years, still doesn't dare to guarantee anyone that he can solve all cases. Even the legend of the Japanese police circle, Hiratsuka Hachibei, the former head of the first search section known as the first person in the Japanese criminal police, finally lost his name in the 300 million yen robbery.

"You have to do it, you must not drag this case until the train arrives in Aomori!" Ishibashi Heizo said to Lin Shuichi in an emotional and commanding tone. When he said this, he immediately realized that he had made a mistake, how could he talk to the police of the Metropolitan Police Department, or to a police department. The other party is also a middle-level bureaucrat in the police world!

"I'm sorry, I was rude!" After Ishihashi Heizo, who knew that he had lost his words, calmed down, he immediately bowed deeply to Lin Xiuyi, and then said sincerely.

"But if you can't help, then today's Senhoua train will probably be the last Cassiopeia train......8)
