Refuse to allow Conan to join the main storyline

When the bell rang, Matsuura Shun immediately announced the end of get out of class.

These were not the most difficult 45 minutes in his life, but they were the most unbearable 45 minutes.

He is Matsuura Shun, a graduate student of the Department of Chemistry at the University of Tokyo. He should have had a perfect life, but his life plan and everything he had were ruined by an experimental accident. Moreover, he was not the original cause of the experimental accident, he was just an unlucky scapegoat!

But no matter how he explained, how he struggled, or how he proved his innocence, he was still convicted, expelled, and ruthlessly thrown out of the school!

It's obviously not my fault! It's my instructor! It's the school! It's this damn system!

During the following two years of low life, Matsuura Shun came into contact with the dark web and saw the wonderful other side of the world.

Using the knowledge he learned, Matsuura Jun produced and sold some rare chemical products, and gained considerable reputation on the dark web for his high quality, rarity and accuracy. With this skill, he earned his first pot of gold and established his own small laboratory.

After that, some people even came to him to win him over, saying that they wanted him to do some "taboo research" with them.

A bunch of middle school patients!

Matsuura Shun ignored those guys. There was only one thought in his mind: revenge!

Where should I start?

Matsuura Jun cheered up, passed the teacher qualification examination, and was eventually hired by Victoria Private Elementary School. He finally found his foothold in this society again.

So, let’s start here.

Coincidentally, he bought something quite interesting on the dark web.

The so-called explosives tutorial was a piece of cake for a top student like him. Matsuura Jun quickly learned how to make a "Pramya" brand time bomb.

But his own efficiency was too low, so Matsuura Jun turned his attention to his innocent and lovely students.

Matsuura Shun made some minor modifications to the tutorial, removing the most dangerous and easily exposed parts, and distributed the assembly of the casing and circuits as children's handicrafts, under the pretext of "asking them to help make some small preparations in advance for the next chemistry experiment."

Except for a few particularly stupid idiots, most of the students completed their handicrafts, and some of them even produced works that could be called perfect.

So Matsuura Shun organized several special activities, took these people to the underground warehouse, and assembled more semi-finished explosives.

In order to increase their interest, Matsuura Shun also specially customized a large number of wires with beautiful colors and bought them the most expensive tools.

The results are remarkable.

Every time he looked at half of the warehouse filled with unfinished bombs, Matsuura Shun would sincerely become more patient with those kids.

However, because his chemical laboratory did not need too much gunpowder, his stock was exhausted. So he found the largest gunpowder supplier in Tokyo on the dark web and ordered a new batch of goods.

Then, for some unknown reason, he was targeted by a female detective named Sakurai Izumi.

But it’s not a big problem. As long as he can get rid of this person without anyone noticing, his plan can still go on perfectly.

In fact, according to the concentration of the bottle of ether in his hand, it would only make a person unconscious for a few dozen minutes, and no more than an hour at most.

Matsuura Jun looked at his watch. 45 minutes had passed. Could the woman have woken up? But he tied her up very tightly. Even if she wanted to get out of the trap, it would take her a long time. If he rushed over now, he should be in time.

Just throw another bottle of ether over there to knock her out. And then...

What a hassle. It would be better to kill her while she is unconscious. Pretending it was hanging was a good idea. It would not make his warehouse dirty and would be easy to clean up.

With these thoughts in his mind, Matsuura Shun walked down the stairs leisurely and reached into the bottle of ether in his pocket.

Inadvertently, he turned his head and glanced out the window of the corridor, and saw a familiar-looking man walking hurriedly towards the teaching building downstairs.

Hey, that person...

I remember it was the parent who brought his child here for the interview today.

Didn't he go back? Why did he come back again? And he didn't bring his child with him this time...

Ah, I see. Are you here to "talk about investment"?

Hum, capital...

Matsuura Shun withdrew his gaze and continued walking downstairs.

Just as he was about to walk up the stairs leading to the basement, an alarm suddenly sounded in his ears.

Matsuura Shun frowned.

Fire alarm?

He turned around to look at the corridor and didn't find anything unusual, so he leaned out of the window and found that black smoke was indeed coming out of a side window on the first floor.

That's the storage room?

Moreover, Matsuura Shun noticed with his sharp eyes that the figure who was suspected to be the student's parent flashed past the corner of the teaching building and ran into the blind spot of his sight.

Matsuura Jun felt something was wrong and immediately ran towards the storage room on the first floor. There were three other male teachers who had the same reaction as him, so Matsuura Jun's behavior was not out of place.

When they pushed open the door of the storage room, the teachers were frightened by the billowing smoke. They hurriedly ran away, calling on the students who were watching nearby to evacuate immediately.

After all, the school spends a lot of manpower and material resources on fire drills and earthquake drills every year. No matter what, since the alarm sounds, we must respond immediately. Otherwise, if we are judged as dereliction of duty afterwards, we will be doomed.

The teachers began to run into the classes they were responsible for and direct the students to retreat in an orderly manner.

Matsuura Shun stood at the door of the storage room for a while, his eyes flickering.

There was smoke but no fire, a fleeting figure, the parents of students who came and went, Sakurai Izumi's video commentary disguised as a personal investigation, the delivery truck in the morning... a series of things flashed through his mind quickly.

Could it be that there was a problem with the shipper? Otherwise, how did his personal information get leaked?

He clearly did not leave any personal information on the dark web, and was very careful not to show up during transactions. He always paid agents to conduct transactions, and the pickup and delivery of goods were always passed on multiple times to prevent any possible leaks in the middle.

He has been so careful, what exactly is the problem?

Escape, must escape immediately!

Matsuura Shun quickly ran up to the second floor, ready to take away all the important things he had left in the office.

He was about to push open the window on the second floor when he suddenly noticed something unusual.

The street, which is usually very busy, was now completely quiet with not a single car on the road.

Although these people sitting or standing on the street were all dressed like ordinary passers-by, they all had serious expressions, their eyes occasionally fell on the teaching building, and they all wore headsets.

Every one of these people is in plain clothes!

Matsuura Shun felt a chill in his heart.

It turned out that his intuition when he saw Sakurai Izumi was right! That woman didn't come here alone to investigate. She was here to help the police divert his attention and cover up for them!

Matsuura Shun cursed in his heart, turned around and ran out of the office.

Damn it, Detective Sakurai, you fooled me so badly! If I hadn't been alert, I would have almost fallen into the police's trap!

Damn it! Die! All of you die!

As soon as he stepped out of the office door, he heard a voice behind him shouting, "Teacher Matsuura!"
