Detective Conan: Knifeman? I'm a good citizen of Beihua

Sakura Police School, located in the suburbs of Tokyo, is affiliated with the Metropolitan Police Department. It is a product of Sakura's modern police system. It is responsible for the pre-job training of new police officers in Sakura and is one of the main sources of Sakura police.

Since its establishment, the school has attached importance to theoretical knowledge while also focusing on practical exercises and personality training. It has rich teacher resources. Countless outstanding police officers have graduated from here, and countless students are full of admiration for this place.

Today, it should have been a normal training time, but the school was unusually silent.

A row of police cars were parked at the gate, and the students who were supposed to be in class stopped outside the school to watch, huddled together and whispered to each other.

In the police car, Kenji Hagiwara and Jinpei Matsuda, who were wearing black uniforms, got out of the car and looked at the huge stone tablet at the door, feeling a lot of emotions in their hearts.

Hagiwara Kenji let out a long sigh, pointed over there, and said to Matsuda Jinpei with a smile, "I remember that was where we took our group photo. I never thought seven years would pass in the blink of an eye."

Matsuda Jinpei, cigarette in hand, glanced over from behind his sunglasses, then chuckled, "It's been so many years."

"Matsuda, Hagiwara! It's you two!"

A rough voice came from the other side, and a fierce-looking, burly man slowly walked over.

"Hey, Ghost Boss~" Jinpei Matsuda was the first to greet.

As a student who was often punished by Hachizo Onizuka, after so many years, he still couldn't change his bad habit of being lazy.

Hagiwara Kenji was a little more polite and nodded slightly: "Instructor Onizuka, long time no see."

Onizuka Yazo looked at the two of them with a satisfied look on his face: "Not bad, not bad. I heard that you two have made great achievements many times and have a bright future ahead of you."

He glanced at Matsuda Jinpei and slapped him on the back of the head. "I've told you so many times, you have to be serious and rigorous in your work. Don't try to be cool by slinging a cigarette between your lips while working. People will think we're only training thugs."

Matsuda Jinpei choked and almost swallowed the cigarette. He helplessly covered the back of his head with one hand and took out the cigarette with the other hand: "I know, I know, Boss Ghost, after all these years, you should change your bad temper."

"What? Why? After all these years, you still dare to teach me a lesson?"

Onizuka Hachizo's eyes widened in anger, while Hagiwara Kenji suppressed his laughter and tried to calm the master and apprentice: "Let's get to work first, and then catch up after we're done."

Matsuda Jinpei crossed his arms and muttered, "What good is there for me and him to reminisce about?"

Onitsuka Yazo snorted and laughed: "You kid, it's better to be able to dismantle it. If you can't, I promise to make you go back to the furnace and rebuild it."

Where is this? The Police Academy! Most of the teachers here are retired officers or current officers, and the teachers who specialize in bomb disposal are experts in the field!

Even they couldn’t dismantle it, so they had to ask for help from the mobile team. You can imagine how complicated the bomb was!

If this matter were to get out, it would become a small-scale joke in the industry.

Hearing Onitsuka Yazo's words, Matsuda Jinpei became interested: "Then I want to see what kind of bomb even our police academy teachers can't dismantle."

Onitsuka Hachizo glared at him and said, "Whether we can demolish it or not, just keep your mouth shut. You all know that those old experts have bad tempers. They might even talk behind your back again."

Jinpei Matsuda and Kenji Hagiwara showed great talent in bomb disposal when they were in the police academy. Kenji Hagiwara was okay, being more tactful and not so ostentatious, but Jinpei Matsuda was different. He could dismantle an experimental object that even the teacher couldn't dismantle, without giving the teacher any face at all.

For those arrogant experts, this was a slap in the face, and they naturally held a grudge against Jinpei Matsuda.

Hachizo Onizuka didn't know how many times he had been pulled over and scolded by those old guys, saying that Jinpei Matsuda disrespected the teacher and disrupted classroom order.

Matsuda Jinpei was clearly thinking back to the past, and chuckled, "I think they're just taking advantage of their age. Staying stuck in school, they naturally can't keep up with the changing times, and it's normal they can't defuse the bombs of the new era. As for their love of gossiping behind my back, I don't mind."

Hachizo Onizuka's blood pressure instantly rose.

"Oh, don't worry, Instructor Onizuka. Matsuda has always been like this. They should know it very well." Hagiwara Kenji put his hand on Matsuda Jinpei's shoulder like a protective child. "Anyway, those people can say whatever they want. We can't hear it. The sooner we finish it, the sooner we can get out of here. Don't stay and listen to their sarcasm."

Matsuda Jinpei: "That's what I meant."

Although the police academy did leave me with many unforgettable memories, and Instructor Onizuka is actually a very nice person, but... some guys are really annoying.

Onizuka Hachizo opened his mouth, wanting to say a few more words, but looking at his two most proud students, he finally sighed and said, "Forget it, forget it, I won't say anything to you."

The group walked all the way to the office building and went straight to the fifth floor.

The bomb was found in the fire hydrant in the corridor. Several members of the bomb disposal team were already waiting there. However, the bomb disposal experts that Onizuka Hachizo was worried about were not there.

I guess he knew that Matsuda Jinpei's words were rude, so he slipped away first.

"According to the information left at the scene, there should be a few more distributed inside the school, but we are still investigating them, so I will give this one to you first." said Yazo Onizuka.

Kenji Hagiwara nodded in agreement, but Jinpei Matsuda seemed distracted, not knowing what he was looking at.

Kenji Hagiwara quickly tapped Jinpei Matsuda's arm with his elbow.

Matsuda Jinpei came to his senses and immediately said, "No problem."

Hachizo Onizuka did not stay and left the scene directly, leaving only the bomb disposal team members who were responsible for bomb disposal.

Hagiwara Kenji was a little surprised: "Xiao Zhenping, what were you thinking about just now?"

Matsuda Jinpei opened the toolbox and pointed in another direction: "Over there——"

Hagiwara Kenji followed his gaze.

At the end of the corridor is the police academy's archive room!

For various reasons, Sakura is still a country that prefers paper archives. Although Internet technology has become increasingly advanced, the old guys who control most of the resources and power are still nostalgic and have not innovated the old management methods.

This often leads to the situation that if a fire occurs in a relevant data room or the old storage space is replaced with a new one, archival materials will often be lost. Disputes caused by this situation are common every year.

Therefore, the archives room is basically a very important key protection area in a place.

As for the police academy, needless to say, the information inside is of paramount importance.

But today is a little special. A time bomb was found here and everyone on the entire floor has been evacuated.

Almost at a glance, Kenji Hagiwara understood what Jinpei Matsuda meant.

"You mean the Shirakawa incident?"

Hagiwara Kenji asked in a low voice.

"Yeah," Matsuda Jinpei responded, "it ended so abruptly back then... Didn't Hagi have any doubts in his heart?"

Hagiwara Kenji curled his lips: "How is it possible? If Shirakawa hadn't refused..."

"But after so many years, the files inside may have been updated long ago."

This is the truth. After all, one archive room cannot hold so many years of student information. Every once in a while, the information will definitely be transferred to a more secure archive.

In particular, information that needs to be kept separately, such as information on certain important police officers, will be transferred to a higher-standard place and sealed to prevent it from being snooped by interested parties.

Kenji Hagiwara felt that even if he went in and looked through it now, he might not find any useful information.

"But this opportunity is rare." Matsuda Jinpei stared over there and whispered, "I've encountered the same type of lock in the archives room before, so I'm sure this one can be opened. We're the only ones here this time, so I'll just go in and take a look around."

Jinpei Matsuda has never been a man who follows the rules. If possible, he hopes to help his friend find out the truth of what happened back then within his limited abilities.
