Refuse to allow Conan to join the main storyline

The five people in dormitory No. 144 were assigned to different departments with their own work and rest schedules. Today, it was a rare occasion that all of them returned before lights out.

Everyone was chatting in the study room, introducing each other to the situation in their respective departments. Kenji Hagiwara looked at the time and stood up again to look out the window.

Zhu Fu Jingguang asked: "What's wrong, Hagiwara? It seems that you are a little restless today?"

Hagiwara Kenji smiled and said, "There is a guest who has an appointment but has not arrived yet."

"An appointment guest?" Zhu Fujingguang glanced at the window and immediately responded: "Heijiang?"

Fūya Rei was concerned about another point: "Is it an appointment?"

"Well, when we met yesterday she mentioned that she needed books and notes on explosives, so Jinpei and I put together a copy for her."

Idahang frowned slightly: "Speaking of which, have there been more cases related to explosions recently?"

Matsuda Jinpei was busy disassembling a watch when he suddenly looked up and said, "Come to think of it, I seemed to smell chocolate in your mouth yesterday."

What kind of weird focus is this...

Everyone was speechless.

Idahang was speechless for a long time before he replied, "My girlfriend is here. But when you arrived, I asked her to take shelter in another store nearby."

"Tsk!" Matsuda smacked his lips in an unclear manner.

Hagiwara Kenji smiled and opened the drawer to show him the chocolate he received: "Do you want to eat it?"

Jinpei Matsuda unceremoniously reached out and grabbed the two most expensive-looking pieces, then continued to tinker with the things in his hands.

Kenji Hagiwara picked up two more pieces and threw them to Furuya Rei and Morobushi Kagemitsu, then looked at Date Kou and closed the drawer.

The time was approaching half past ten, and just when Hagiwara Kenji thought that the black cat probably would not come today, there was a sudden "click" sound from the window.

Kenji Hagiwara immediately turned his head and looked, but there was no cat outside the window, nothing at all.

Then there was another "click" sound.

This time Hagiwara saw clearly that it was the sound of a small stone hitting the window.

Kenji Hagiwara opened the window and looked out, then exclaimed "Huh" in surprise, then walked away from the window.

A moment later, a figure climbed in through the window, raised the brim of his hat slightly, and smiled at the people in the room, "Good evening."

"Sakurai?"

"Sakurai!"

Koizumi's appearance indeed caused several exclamations.

Kenji Hagiwara walked to the window and looked out. He was relieved to find that everything was quiet and there was no one around.

"Didn't you tell the cat to come over? Why did you come here by yourself?"

Xiaoquan smiled and said, "Didn't you say that there were so many things that you were afraid the cat couldn't carry them? It just so happens that I have something to ask you, so I'll make this trip myself."

She looked up at the people in the room, hesitated for a moment, and asked, "...Hey, you should have bomb disposal tools, right?"

"Eh?!"

Knowing that this person would not speak without a purpose, the five people were all shocked.

"You didn't find a bomb nearby? Where is it? It can't be inside the police academy!"

Fūya Rei even looked directly at her backpack: "You wouldn't..."

"Um……"

Koizumi took off his backpack and placed it on the long table, then opened the zipper so that everyone could see what was inside.

That was the time bomb she had summoned just before going upstairs.

Seeing that there were more than 6 minutes left on the LCD screen, the five people in the room immediately took action without any discussion.

Jinpei Matsuda dragged a chair over and sat down to start studying the structure of the bomb.

Kenji Hagiwara ran back into the house and took out his toolbox.

Zhu Fu Jingguang and Furuya Ling quickly cleared away all the things that were in the way on the long table.

Ida Hang pulled all the lamps on everyone's desk to increase the light source.

Koizumi touched her nose a little embarrassedly, but fortunately everyone's attention was focused on the time bomb at that time, and no one noticed her guilt and embarrassment.

She originally wanted to practice with the time bomb in the storage space, but because she was afraid that she was not skilled enough and might cut the wrong line, she decided to take this opportunity today to let the two bomb disposal experts take a look.

She was very confident that she could ensure its safety. At worst, she could just take it back before the time was up.

But, she still scared everyone...

She came close to Matsuda Jinpei, pointed at one of the wires and asked, "It should be safe if we cut this one, right?"

Matsuda Jinpei didn't even raise his head: "Unrelated people..."

Feeling his collar being grabbed again, Matsuda Jinpei immediately changed his words: "...You guessed right."

Koizumi said "Hey" and loosened his collar: "I know a little bit, okay."

Matsuda Jinpei turned his head and glanced at her, then suddenly stood up and stood aside, his hands folded across his chest: "Then you do the cutting."

Koizumi: ...

I'll come if I want!

She reached out and picked up the wire cutters that Jinpei Matsuda had thrown on the table, gestured with them awkwardly, and turned to look at Jinpei Matsuda.

Matsuda crossed his arms, raised his eyebrows at her provocatively, and said nothing.

Koizumi: ...

He turned around and looked at Kenji Hagiwara again.

Hagiwara smiled, but it was unclear why.

Koizumi: “…Then I really cut it.”

Matsuda Jinpei sneered: "You still say you're not just guessing?"

Koizumi: ...

Well, since you guys won't stop me, then it's fine! I'll do it then!

Koizumi secretly made preparations. As long as there was the slightest sign of explosion, he would quickly put the thing back into the storage space, then gritted his teeth and cut the fuse.

The ticking sound of the time bomb stopped and the numbers on the LCD screen stopped decreasing.

Seeing this, Koizumi waited for another two seconds to make sure that there was no problem. Only then did he return to normal with his breath and his heartbeat gradually stabilize.

My god, things like bomb disposal are still so exciting even if you are 100% sure of safety.

She couldn't help but breathe a sigh of relief: "Matsuda, Hagiwara, didn't you two feel scared when you were defusing the bomb?"

Matsuda Jinpei pushed her aside, sat back in front of the bomb and began to dismantle it: "Is being afraid useful?"

Hagiwara Kenji also smiled and said, "Compared to a slow death, at least this is less painful?"

Koizumi: ...

I felt like my heart was cut by a knife.

Seeing that both of them looked indifferent, Matsuda Jinpei even planned to continue the dismantling work. Koizumi said with a gloomy face, "I told you, even a bomb that has been dismantled may still explode."

The five people who had originally relaxed were all stunned. Matsuda Jinpei and Hagiwara Kenji even froze and suddenly turned to look at Koizumi.

Koizumi shook the remote control in his hand and sighed, "You really don't learn from your mistakes."

Humph, I told you to dare to stab me, but I can’t scare you to death!

------

Watching Koizumi putting the disassembled time bomb and remote control into her backpack, Hagiwara Kenji asked in confusion: "Why don't you give the bomb to us? According to the process, these things should be collected and destroyed in a unified manner."

Koizumi: “I am still useful.”

It would be disastrous if these things disappeared right under your noses!

Five people:……

It worked? You're not going to try to put it back together, are you?

"So where did you find this bomb? Was it in the police academy?"

Koizumi: ...

Well, this is a little hard to explain, so just use your imagination.

Yi Dahang slammed the table and said angrily: "These bastards are really getting more and more outrageous! Not only did they throw it at the door of the police station, they even ran to the police academy to drop dangerous goods! What on earth do they want to do!"

Furiya Ling suddenly asked: "Sakurai, does this group of people have anything to do with your mission?"

"Probably not." Koizumi answered simply, "But I'm still investigating."

As she spoke, she casually stuffed the study materials that Hagiwara had prepared for her into her backpack.

At this moment, Matsuda Jinpei suddenly saw Morobushi Kagemitsu coming over with a disposable water cup. He rolled his eyes and quickly walked over to intercept the cup and took it away. In the puzzled look of Morobushi, he said with a sly smile, "I'll do it, I'll do it."

While Koizumi was answering everyone's questions, she saw Matsuda Jinpei placing a familiar small bowl on the table next to her.

Eh? Isn't this the cat bowl I used to drink water when I turned into a black cat?

Matsuda Jinpei laughed strangely: "I didn't know you were coming here, this is all I have. Make do with it."

Koizumi: ...

Do I dislike the things I use?

Pick up the small bowl and drink it all.

Then she glanced at Matsuda Jinpei and said, "Oh, you childish boy."

Then, she took out five chocolate bars from her pocket, threw four of them to Date Kou, Furuya, Morobushi, and Hagiwara respectively, and the fifth one... she unwrapped it and threw it into her mouth: "Let's go, bye."

After saying that, he picked up his backpack and left through the window.

Matsuda Jinpei:......

Who is the childish one after all!
