Yin Dahang followed closely behind Fujiwara Yoo, and the two took the elevator all the way down, until they entered the parking lot and made sure that there was no one else around, and then he asked his doubts: "Why did you ask Yuji to retrieve the eucalyptus file that happened in Fuchu City six years ago, it must have something to do with the eucalyptus file on the day of the first day of school, right?" Fujiwara Yo couldn't help but pause when he opened the door, he raised his eyes and looked at Yin Dahang without answering in a hurry, and after sitting in the car and fastening the safety belt, he nodded silently.

It was impossible for him to forget the eucalyptus that he had faced with Matsuda Jinpei six years ago, and the follow-up to that eucalyptus, Onizuka Hachizo, did not mention it to himself, but only asked a question that made him wonder even now when he recalled it.

——

"Fujiwara, you were the only one who participated from scratch last night, and when you recorded your confession, you made it clear that you were hit in the head because someone threw a hypnotic gas bomb, right?" The change in Onizuka Hachizo's expression after receiving his affirmative answer is still remembered by Fujiwara Yoshi, so the case was not resolved, and the mastermind behind the scenes was not arrested...... But why did the Metropolitan Police Department choose to hastily form eucalyptus?

After Yin Dahang saw Fujiwara Yoo's nod of affirmation, he took out a toothpick from the physical evidence bag in his pocket and put it in his mouth, and his logical reasoning ability was also very strong, and he knew the problem after a little thought: "No wonder you asked Yuji to retrieve the file that has been closed, when the previous department was first established, you asked us to sort out all the unresolved suspense that existed in the Metropolitan Police Department, and you noticed at that time that this case was classified as a eucalyptus case, right?" ”

"Well, I didn't think much of it at the time, if only I pulled up the file out of curiosity and took a look." Fujiwara's brows furrowed tightly, this case meant a lot to him, it could be regarded as the first case he had handled.

"There are some things that can't be changed, and you don't have to be in a place like this."

"yes, there are some endings that can't be changed." The two drove to Fuchu City and spent nearly an hour arriving at the 2-chome apartment building in Honjukucho.

This apartment with a good location was rented by Chie Matsuoka, and after graduating from high school, she joined the society and moved out of the house directly after becoming financially independent, but judging from the information sent by Yuji Hashimoto...... She changed jobs and rented so often that her profession was in the service industry.

Either a cashier at a convenience store or a waiter at a family restaurant are some professions that don't pay well, but these positions happen to not care about your resume and education.

The apartment building is tucked away in an old street, the surrounding environment is very dilapidated, and the wall on the first floor near the staircase is splashed with red paint, which is not the result of debt collection, but more like a cover for those crooked graffiti.

Fujiwara Yu took two steps in one step and quickly came to the door of room 402 where Matsuoka Chie lived, and was about to raise his hand to knock on the door when he found that it was not locked.

Yin Dahang, who also discovered this situation, quickly pulled out the gun on his waist, and after the two tacitly exchanged glances, one was responsible for kicking the door and the other was responsible for holding the gun to remain vigilant.

Peng! The security door that was not strong did not resist Fujiwara Yu's kicking, and the security door that fell to the ground also made his face show a trace of embarrassment, and he didn't expect to kick the door with all his strength.

There was a slight movement in the room, and the two of them rushed towards the source of the sound, only to find the body hanging from the chandelier without any vital signs.

They were still late, and Chie Matsuoka was already dead...... And the time of death was more than six hours.

Yin Dahang stretched out his hand and patted Fujiwara Yoo's shoulder, and said comfortingly: "The corpse has shown obvious stiffness, indicating that she was killed before receiving the letter, do you say that the murderer will notice her and ask for help from the outside world, so we did it before we arrived." ”

"I don't rule out this possibility, but what's going on with the noise just now?" Just when the two of them were puzzled where the strange sound came from in the room, a hand suddenly stretched out on the edge of the bed, and when they realized that there was a third person in the room in addition to the body, Yin Dahang did not hesitate to aim the gun at the side of the bed, and shouted: "Who is it?" Hands up! ”

"I'm a police officer, not a ...... Hey? Monitor? fuji？ How did you end up here? The man who pulled him on the edge of the bed to support himself to sit up was Matsuda Jinpei, and when he got up with a curse, he saw that the person with a gun aimed at him was Yin Dahang, so he swallowed the rest of the words back.

Matsuda? Why Matsuda? Fujiwara Yu tightened his brows and was a little panicked in his heart, could it be that the mastermind who didn't arrest Gui Yu back then had already noticed that Sosuke Takaji was Fujiwara Yo?

This coincidence made him wonder about the possibility.

"Matsuda?!" Yin Dahang's expression was even more surprised than the other party, he quickly stepped forward to support Matsuda Jinping, whose legs and feet were a little weak, and asked out loud: "We just want to ask you, why are you here?" Matsuda Jinhei rubbed his back with one hand and explained why he fell here: "Didn't I go on a business trip the other day? As soon as I got home yesterday, I fell asleep, and when I woke up, I found that there was a letter stuffed in the crack of the door, and there was only a string of addresses on it, which belonged to a convenience store. I thought it was a little strange, so I went to Fuchu City alone to investigate, and after asking the owner of the convenience store, he said that there was only one female employee at the convenience store, and it was Chie Matsuoka, who had quit her job a week ago, so I came here. Fujiwara Yu wondered why Chie Matsuoka would look for Matsuda Jinpei, you must know that Matsuda is not a person who searches for a lesson, and if he asks for help, he should also go to the Fuchu Police Station.

And even if she remembered herself, she shouldn't remember Matsuda, she hadn't met Matsuda.

"Why did you fall at the scene of your death?" Yin Dahang asked. Matsuda Jinhei looked at the body hanging from the chandelier, and was silent for a few seconds before he scolded angrily, "...... When I entered the room, I was attacked. ”

"Anyone else can sneak up on you?" Fujiwara raised an eyebrow and asked.

"Cut, it's just despicable." Matsuda Jinpei lifted his clothes and glared, "Look, haven't you tried the power of the stun gun?" Fujiwara Yu rolled his eyes, he naturally tried, and was even stuffed into the trunk of the car by the gangsters.

He didn't reply, he stepped on the bed and took advantage of his height to easily remove Matsuoka Chie's body from the sling, and in the process of examining the body, he found that the victim had several thoughts of suicide.

There are no less than ten marks on the wrist of the wrist, why would a person who has suicidal thoughts write a letter for help to himself?

"It's not a suicide, is it?" Matsuda Jinhei asked with his hands in his pockets. Fujiwara Yu stared at the ditch around Matsuoka Chie's neck for a long time, then shook his head silently.
