Refuse to allow Conan to join the main storyline

Koizumi heard Matsuda's sly voice saying, "Hey, Sakurai-san, it's time to test your learning results."

She pulled the corner of her mouth and said in Matsuda's tone: "Hey, Mr. Matsuda, it's time to test your teaching level."

"Hey, you can still tell jokes. It seems you are in good shape."

"It's OK. I'm just a little dizzy and nauseous. I might have misjudged the color of the wire."

Matsuda Jinpei sneered: "How funny."

"Thank you for the compliment, but unfortunately this is not a joke. Wait for me for half a minute..."

Koizumi couldn't hold it in any longer and held onto the wall to retch. Fortunately, she had barely eaten or drunk anything today, so her stomach was empty and she couldn't vomit anything.

Listening to the noise from the other side, Matsuda Jinpei frowned, "Hey, what's going on? If it doesn't work, don't force it. You can wait for Hagiwara and I to go over and deal with it."

"How much ether did that bastard use... Ugh..."

Koizumi stood up slowly, took a deep breath to adjust himself, and said, "I'm afraid I won't be able to wait for you to come. Matsuura Shun is a highly intelligent person with a calm personality and strong self-control, but he is simply mentally ill and very difficult to deal with. I'm worried that Officer Megure and the others' arrangements will not fool this guy at all. To be on the safe side, it's better to get rid of the things here as soon as possible. This is also for my own safety."

Matsuda Jinpei suddenly remembered something: "He didn't tie you up?"

"How is that possible? I just broke free."

Jinpei Matsuda raised his eyebrows.

It's only been a few minutes since you woke up from your coma, and you've already escaped? You're really fast at escaping.

So was there something wrong with the way Matsuura Shun tied him, or did Sakurai just happen to have a knife hidden on hand?

"Okay, I can. Let's get started."

“Do you have any string trimmers handy?”

"I only have a pair of scissors. They are a little small, but they are enough."

"Well, a pair of scissors is enough. First, take a look at the appearance of the bomb. Is it the same as the previous ones?"

"The bags are different. Maybe Matsuura Jun likes to drink red wine, so all of them are paper bags called Qingya Winery."

“Green Bud Winery.”

Jinpei Matsuda repeated the name and turned to look at Kenji Hagiwara who was standing next to him.

Hagiwara was lowering his head and taking quick notes in his little notebook.

Jinpei Matsuda stretched his head to take a look and was immediately speechless.

You should write down something useful. How come you even wrote down my previous jokes word for word?

Noticing that Matsuda Jinpei had stopped talking, Hagiwara Kenji looked up and met Matsuda Jinpei's half-moon eyes.

Kenji Hagiwara smiled and gestured to him, "Please continue."

Matsuda Jinpei rolled his eyes: "Okay, the bags are different, then what? Give me some meaningful information."

"Hehe...does it count if the wires are different colors? Red, white, gray... Hey, where did this guy get rainbow-colored wires? That's weird. Wait a minute, I have a bad feeling..."

Jinpei Matsuda heard a rustling sound coming from the other side, followed by Koizumi's helpless cursing.

"You're crazy! The one next to you uses all these rainbow-colored wires!"

Matsuda Jinpei listened to her description carefully, picturing the appearance of the bomb in his mind, and was speechless: "I now understand what you mean by his mental illness."

"...Ah, I understand."

Koizumi's voice suddenly dropped. She paused for a long time before saying, "There are a lot of semi-finished products next to them, using the same wires. These may be the 'handwork' of his students... this bastard."

"Hey, girls, don't swear."

“…Baga, baga baga baga!”

"Humph, childish... Hey, Hagi, I think you did it on purpose, don't remember these, just cross them out!"

While sorting out the threads in his hand, Koizumi listened to the noise of two people arguing over there. The corners of his mouth lifted up involuntarily, and his originally nervous mood relaxed a lot.

"Hey, Matsuda, I've sorted out the colors. There are five wires here, red, white, and gray. Well, let's call these two orange and green. I remember the tutorial originally said there were supposed to be four wires, right? It seems that Matsuura Shun also made some changes based on the original tutorial. Can you figure it out based on what I've described to you?"

"Idiot, if you don't believe me, then change to Hagiwara." Matsuda sneered, "I can take the initiative to give up my position this time. How do you think?"

Xiaoquan was immediately furious: "If you have the guts, I will never be able to pull your collar for the rest of my life."

She originally thought that Matsuda Jinpei would continue to talk to her, but she didn't expect that as soon as she said this, he changed his tone and his mocking tone suddenly became serious: "Okay, Sakurai, have you found the main power source of the bomb? Remember the steps written in my notes, it may be through a fuse, battery or other forms of energy storage. Find and isolate it."

"finding."

Matsuda Jinpei said patiently, "Don't be impatient, take your time. The first one is the most difficult. Once you understand the structure of this one, the rest will be easy. Be careful, observe the path of each wire, and find their starting and ending points. The main power source is usually located closest to the core of the bomb."

After a while, Koizumi's voice came again: "Found it, this should be it. What next? Cut it off?"

Matsuda Jinpei pursed his dry lips and swallowed his saliva involuntarily, but his words were still relaxed and fluent: "No one will help you check this time, so be careful not to get dazzled. Remember to find something to replace the wire crimper to push aside other irrelevant wires so that the wire can be exposed as clearly as possible. Hold the scissors with a steady hand to ensure that the blades of the scissors do not touch any other wires."

There was a soft "click" sound.

What followed were two breathtaking seconds.

“…Did you cut it?”

“…I cut it.”

Matsuda Jinpei could tell that the voice on the other end was a little dry. He wanted to say something to ease the mood, but his mind went blank in an instant.

"…Hey, I'm still alive."

"...Oh, you are really amazing then."

"Hehehe...Matsuda, you get nervous too. Well, I have some bad news for you. I probably cut it wrong, and the timer started."

Jinpei Matsuda felt a buzzing in his head.

He gritted his teeth, took a deep breath, and said in a calm tone, "How long?"

"five minutes."

"Okay. We need to reanalyze the bomb, and you need to pay attention to…"

Inspector Megure, who had been standing nearby and watching without even daring to breathe, glanced at his watch and reached out to pull Kogoro Mouri, who was also stiff beside him.

The two of them stepped back a considerable distance, and then Officer Megure pressed his hand on his still violently beating chest: "It's time to go, Maori. Are you sure you want to do this? You are not a policeman now."

Maori Kogoro withdrew his gaze from Matsuda Jinpei and said, "Even if I'm not Officer Maori, I'm still Detective Maori. When encountering something like this..."

He took a deep breath and said firmly, "We have to do what we can. Besides, I just went in for an interview this morning. I'm a familiar face, so it won't be too abrupt if I'm the only one going in."

Officer Megure stared at him for a moment, then nodded slowly: "Okay, I'll leave it to you then."
