Refuse to allow Conan to join the main storyline

"So, this was actually a bit of luck. Because the device had an obvious design flaw, it could only be handled in this way."

Hagiwara Kenji continued seriously, "If the exit down here is designed to be closed and can't be blocked with chewing gum, then we'll be in big trouble."

As he spoke, Kenji Hagiwara quickly removed the electronic display screen, revealing the complex circuitry behind it.

"If we start from here, it's possible to defuse the bomb in one and a half minutes, but the time will be a bit tight."

Hagiwara Kenji dropped the screwdriver and said, "But now that you're here, I don't have to deal with this anymore, right?"

He winked at Koizumi and said with a relaxed smile: "Then I'll leave it to you, Izumi-chan."

Koizumi also laughed: "No problem, no problem. But before I put this thing away, I have a question."

Koizumi pointed at the device in front of him and said, "Just now you said that the timing device here uses the same technology as the tutorial. Does that mean that the maker of this thing and the maker of the tutorial are the same person?"

Hagiwara Kenji thought about it and shook his head: "After all, technology is not exclusive, so it's hard to say."

Koizumi: ...

Although Hagiwara said so, she felt that this must be Pramia's masterpiece.

Perhaps the plot had already begun when Inspector Megure gave her the wedding commission.

That means that wedding must have some connection with Pramya.

Former police officer Tsutomu Muranaka and his fiancée who was threatened with death...

It looks like her cat brother will have more work to do.

Hagiwara Kenji hesitated for a moment, but added: "Actually, I also feel something strange..."

Koizumi looked at him and said, "...Are you talking about the countdown sound just now?"

Hagiwara Kenji nodded: "Yes! Izumi-chan, do you think so too? Among all the explosives I've handled, I've never seen one that had a countdown indicator. This feels more like a means of intimidation."

Koizumi frowned: "Maybe because, this is just an 'exam'?"

She paused for a moment, then continued, "But that's where the contradiction lies. If this is really an 'exam', why is there no invigilator?"

Hagiwara Kenji raised his eyebrows: "Didn't you find the surveillance equipment just now?"

"Yes, not one."

Koizumi smiled at Hagiwara and said, "If there was, would I let you say such sarcastic words? Aren't you afraid that people will do something desperate if they hear it?"

Hagiwara Kenji scratched his head: "Eh, is that so? I thought there was a surveillance device but you have solved it."

Koizumi: “So, rather than being a ‘test,’ it actually felt more like an intimidation, or a provocation, announcing to us that she was back and ready to act.

"But provocation is definitely not without reason, it must be a purposeful act. So what is the purpose of this person doing this?"

[Declare to us]...

The corner of Kenji Hagiwara's eye twitched, and he suddenly realized a problem that he had not noticed before.

As Koizumi spoke, he waved his hand and put the extremely shabby explosive device on the table into the system's storage space.

However, just as the device disappeared from their sight, another object on the table came into their sight.

Another envelope.

An envelope hidden under an explosive device.

The style looked exactly like the one she had just received at the bridal shop.

Koizumi and Hagiwara looked at each other, reached out to pick up the thing, opened it, and pulled out the letter inside.

【BOOM! 】

There was still no signature at the beginning, just four enlarged, bolded letters with a huge exclamation mark at the end.

Koizumi frowned.

What does it mean?

Manual explosion?

Does this mean that the time bomb just now actually has a remote control device?

She deliberately didn't detonate it. Was she actually letting it go?

its not right……

At this time, there were no pursuers behind them and no surveillance equipment here.

The envelope was placed under the time bomb. Did the bomber assume that they would be able to see the letter safely?

Assuming they will be safe...

Like a countdown to intimidation...

An idea suddenly flashed through Koizumi's mind.

She strode to the window and looked downstairs.

In a flash, the refreshed time bomb appeared on the sidewalk downstairs, but the one with the duct outlet not covered with chewing gum.

Hagihara Kenji hesitated: "Sakurai..."

Koizumi stared at the explosive device: "Hagiwara, if I'm right, we may have been fooled."

Hagiwara Kenji: …

The two of them looked down at the thing on the sidewalk and waited in silence.

A minute and a half later, the shrill alarm sounded again.

The old man who was watching the horse racing in the duty room on the first floor was finally alarmed, and he pushed open the door and ran out to check the situation. When he saw the thing placed at the door, he curiously came forward to take a look.

But after seeing the countdown on the electronic display screen, the man seemed to suddenly react. He screamed in fright, turned around and ran back into the building.

The ten seconds passed quickly.

Although standing on a high place, Koizumi and Hagiwara Kenji could clearly see that the liquid in the glass jar was rapidly decreasing.

Soon, pink and blue flowed all over the ground...

"Sure enough... this is just a fake bomb, and the countdown is really just a threat."

Koizumi took another look at the [BOOM! ] in his hand and couldn't help cursing, "Is this the so-called 'final exam'? Pramiya, that bastard, used this thing to lure us here, what on earth did he want to do?"

"…What if the purpose is to attract your attention so as to delay time?"

Koizumi suddenly looked at Hagiwara Kenji.

Hagiwara's face looked very ugly.

"Sakurai, the last letter Pramya sent you, if the 'ur' above was not just talking about you, but about all of you..."

Koizumi's face suddenly changed.

"Hagiwara, call Matsuda right away and check on his situation!"

As she said this, Hagiwara Kenji took out his cell phone and quickly dialed Matsuda Jinpei's number.

"Drip...drip..."

However, there was only a constant busy tone on the phone.

Jinpei Matsuda, who was always very fast at answering the phone, unexpectedly took a long time to answer the phone.

At the same time, Koizumi also sensed the position of Jinpei Matsuda in his mind.

Then she discovered that Jinpei Matsuda, Rei Furuya, Kagemitsu Morofushi and Kou Date were all together at the moment.

Matsuda Jinpei did not move, but the positions of Furuya Rei, Morofushi Kagemitsu and Date Kou were moving rapidly within a small range.

There is a situation!

Koizumi casually grabbed a handful of five-yen coins and stuffed them into Hagiwara Kenji's coat pocket, saying quickly, "Hagiwara, ur doesn't just refer to you, it refers to us! Xiao..."

Before she could finish the word "heart", she had disappeared from the spot.

Of course, Kenji Hagiwara understood the meaning of Koizumi's last words.

Although Koizumi had already left, he still saluted seriously at the place where Koizumi had just stood: "Yes, sir!"

But soon after, Hagiwara became worried about the locked door.

If Sakurai was there, a broken door lock wouldn't be enough to stop them.

But the problem is that now he is the only one left...

Kenji Hagiwara grabbed the door handle and tried hard, but it couldn't be opened.

The door lock must be completely broken.

He reached for the saber in his pocket.

This thing is fine for defusing bombs, but it's definitely not suitable for defusing doors.

The remaining options are...

Kenji Hagiwara looked at the door panel, then stared at the alarm number on the dial-up interface of his mobile phone and hesitated for three seconds. He put away the phone, turned around and walked towards the window.

It’s just the third floor, hmm.
