Refuse to allow Conan to join the main storyline

The moment Matsuura Shun turned his head, he put on the mask of a good teacher again: "Koyamada-san? Why are you still here? Go downstairs and take shelter!"

Oyamada scratched his head and laughed innocently, saying, "I, I came to inform Mr. Matsuura to take shelter. I was afraid you were too busy with work to notice."

This stupid kid.

Matsuura Shun cursed in his heart and was about to chase the man away, but a thought suddenly flashed through his mind and stopped him from saying anything.

He took Xiao Shantian's hand and walked downstairs, saying gently: "You are such a silly boy, how could the teacher not notice it? But the teacher has to go to the basement to get something first."

Oyamada's eyes widened: "Hey, have you found the key?"

Matsuura Shun knew that the key that Oyamada lost was taken away by Detective Sakurai when he was moving things into the warehouse in the morning, and now he only had a spare key. But he said, "Yeah, I found it. It fell in the corner of the warehouse door."

"Eh?" Oyamada scratched his head. "I looked for it many times but couldn't find it. Matsuura-sensei, you are amazing. But, what are you doing in the warehouse now?"

Hearing the child asking this question as he expected, Matsuura Shun showed a mocking smile on his face for a moment, but said with full emotion as if singing an aria: "Of course, we are going to rescue your 'handicrafts'. We spent so much effort to make things, we can't let them be burned by the fire. These are important memories of us."

As expected, Oyamada took the bait.

The child was originally a very emotional but simple-minded person. He was feeling guilty about his mistakes in the morning. After hearing such emotional words, he was immediately moved to tears. He shouted, "I want to go too! I want to help the teacher get it!"

"But……"

Matsuura Shun acted embarrassed.

Oyamada grabbed his arm and shook it hard: "Let me go, let me go, Mr. Matsuura, I can help! There are so many things, you can't carry them all by yourself."

After "considering it over again and again", Matsuura Shun sighed and compromised: "Alas, there is really nothing I can do about you."

At the fork in the stairs, Matsuura Shun solemnly handed the spare key to Oyamada and said seriously, "Oyamada-san, our important memories are now in your hands to protect!"

"Ok!"

Oyamada didn't even think about why he was the one who suddenly went to the warehouse to get something. He just felt very happy to be entrusted with an "important matter" and ran down the stairs with the key.

Matsuura Shun looked at the child's back disappearing around the corner of the stairs, a smug smile appearing on his lips.

Okay, go ahead, you little idiot.

Although you are a really good helper, you are involved in too many parts. Your existence itself is the biggest threat to me.

Go and keep Detective Sakurai company!

Under the remote guidance of Jinpei Matsuda, Koizumi finally successfully dismantled the first bomb.

With the successful experience, her self-confidence increased greatly, and her bomb disposal speed became faster and faster.

Seeing that the progress was already halfway through, she suddenly heard a noise coming from upstairs.

Koizumi stopped what he was doing and asked, "Matsuda, what's going on? It's suddenly chaotic outside."

Matsuda Jinpei was moving quickly, and answered in a somewhat unstable voice: "Mouri Kogoro sneaked into the school and set a fire, which caused a fire alarm. Now all the teachers and students in the school are evacuating outside the teaching building. Officer Megure has led a team to guard the school, just waiting for the guy named Matsuura Shun to show up and arrest him. Hagiwara, your big assistant and I are also rushing to the school. How many more do you need?"

Koizumi glanced at the paper bag beside him: "Five."

"Good efficiency, keep it up."

"Ah."

Koizumi responded, tilted her head to rub the sweat running down her temples on her shoulder, and continued to concentrate on studying the bomb line in her hand. But not long after, she suddenly heard an unusual sound.

Someone was running down the stairs quickly.

Is Matsuura Shun back?

Koizumi's eyes fixed. She dropped what she was holding, dodged to the door of the warehouse and hid behind it, waiting for the person outside to come in so that she could knock him down immediately.

However, as the footsteps became clearer, she felt something was wrong.

Why did the weight and frequency of these steps feel different from what she had heard before?

The key was inserted into the keyhole, and soon the door was pushed open from the outside without any hesitation.

A little kid rushed in and ran towards the unfinished bombs deep in the warehouse, not noticing that there was anything wrong with the half-dismantled bombs and scissors lying on the ground.

Xiaoquan frowned. She listened for a moment and found that there was no one else outside. Then she quietly stood behind the little boy and pressed his shoulders: "Boy, who are you?"

Matsuda Jinpei's vigilant voice immediately rang through the headset: "What happened? Did someone enter the warehouse?"

Koizumi didn't have time to answer Matsuda Jinpei's question. She had a bad feeling in her heart, so she quickly grabbed the little boy and asked again, "What are you doing here?"

The little boy was frightened by her and screamed "Ah", and said with a little stammer: "I, I am..."

When he saw clearly that the person standing behind him was a strange young woman, Xiao Shantian bravely asked back: "Who are you? Why are you in the warehouse?"

Koizumi frowned, deliberately grabbed his shoulders harder and asked loudly: "Tell me! What are you doing here?"

Feeling the pain, Oyamada panicked again. He tried to break free from Koizumi's grip and shouted, "I, I will help Mr. Matsuura save important memories!"

Koizumi's hair stood on end instantly.

She hugged the little boy in her arms, turned around and ran outside, shouting, "Matsuda, you're exposed, don't come in! He wants to silence us, he wants to lure..."

"boom!"

Jinpei Matsuda just ran to the school gate at this time. Koizumi's voice was still echoing in his ears when it was covered by the shrill roar.

The teaching building in front of him suddenly shook violently, and a large amount of dust flew up from the ground.

The noise on the playground suddenly disappeared, and everyone turned their eyes to the teaching building where the unusual noise came from.

The students who were playing and laughing were stunned.

The teachers who were waiting for the firefighters to arrive out of boredom were stunned.

The police who were searching for the criminal on campus were stunned.

The plainclothes officers who were standing outside the school for surveillance were stunned.

What happened? An earthquake? But wasn't that a fire alarm?

Until the entire teaching building began to slowly tilt and collapse, the playground suddenly became chaotic, and the people shrouded in the shadow of the teaching building began to flee desperately.

A moment later, the teaching building collapsed to the ground and turned into rubble.

Although the teachers had tried their best to lead the students to avoid the direction of the collapsed building, many people were still injured by the flying bricks and stones, injured by falling and being trampled, and crushed under the collapsed building because they could not dodge in time.

Amid the panicked screams and cries, Officer Megure ran up to Jinpei Matsuda, grabbed his collar and shouted, "Where's Sakurai? Where is Sakurai? Has she come out yet?"

Jinpei Matsuda was breathing rapidly, his eyes were red, and he gritted his teeth and couldn't utter a word.

Next to him, Kenji Hagiwara, who had been acting calm and composed, turned pale at this moment. He stared at the ruins in front of him with wide eyes, his lips trembling.

Then, the cat next to them roared and rushed out like a locomotive: "Boss! Boss!"

Jinpei Matsuda and Kenji Hagiwara followed closely behind him, running madly towards the ruins.

After seeing this, is there anything Inspector Megure that you don’t understand?

He lowered his head slightly, stretched out his hand and pressed hard on the hat on his head, his throat rolling. After a while, he suddenly raised his head and roared, quickly issuing a series of instructions: "Call the headquarters for support! Call an ambulance! Have the fire brigade on standby come over immediately and start the search and rescue work immediately! Tell the second and third teams outside to open their eyes and not let go of any suspicious persons. Find the damned criminal! Don't let him get away!"
