"I remember, above the ceiling of that warehouse, there should be a mezzanine space......"

In the president's office of the East Leaf Building, fragments of memories popped up intermittently in my mind, and Kanako Shimazaki raised her hand to cover her head, closing her eyes and trying to recall.

"Mezzanine space?" Conan looked at her suspiciously.

"Well, I have the impression that when designing the ventilation duct on that floor, the construction team directly made a mezzanine space in the ceiling of that floor in order to save costs, and then left a vent in the ceiling of the corresponding room, so as to perfunctory......

No, it's not just that floor, I remember that there are many places in Clover Villa that seem to be cutting corners......"

[Really? 】

Looking at Konanko Shimazaki, who was still trying to remember, the corners of Conan's mouth twitched twice.

He finally knew now why the Dongye Mansion had only been shaken twice by the explosion and started to crook......

Co-authored with you, Clover Villa is simply a dangerous building that cut corners......

"Sister Nanzi, as the architect of Clover Villa, haven't you tried to stop this situation?"

Feeling that Conan's eyes were a little prickly, Konanko Shimazaki silently looked away, and subconsciously defended herself:

"I tried to stop it, but it didn't work......"

She wasn't lying, and in the fragments of memories she had just recalled, she did quarrel over the construction team cutting corners.

But after knowing that the construction team's behavior was actually instructed by Hiromichi Moriyama, she seemed to have given up on this effort.

In my impression, it seems that because of the financial resources of the Moriyama Foundation at that time, it was impossible to build Clover Villa in full accordance with her design, but it was impossible for Moriyama Hiromichi to give up the construction of Clover Villa.

That's why he chose this common "compromise" and finally completed this new Tokyo landmark with a standard that completely failed to meet the building's safety specifications.

[Forget it, now is not the time to discuss this. 】

Without further questioning, Conan looked down at his phone and quickly uploaded another graphic in the software.

He is now more concerned about the situation in the North Leaf Building than about the construction of Clover Hills.

According to the previous declaration of the leader of the liberators, those who were captured by the terrorists and taken to the North Leaf were likely to be killed by them in the end.

Because of the hijacking of the radio tower, he is still unsure if the police outside know what is happening on the artificial island.

In this case, it is obviously unreliable to sit and wait for the police to act, and before the police can actually act, he must first find a way to do something.

Luckily, although Conan is now temporarily trapped in this office, Gray Plains Wai happens to be in the North Leaf.

"Sister Nanzi, are you sure that the ventilation ducts on the first floor of Beiye are all connected?" Conan looked at Kanako Shimazaki and asked.

"It's not so much connected, it's just a whole mezzanine space, just a vent in the corresponding room......"

"In other words, no matter which of the other vents on that floor you enter, you can actually go up to the ceiling of that warehouse, right?"

"Well, that's true...... Alas? Shimazaki Kananko was stunned for a moment, looked at Conan in disbelief, and asked, "Conan, do you want those children to use the mezzanine space to find out the situation in that warehouse?" ”

Conan, who didn't answer her and got an affirmative answer, quickly posted a graphic on that app.

[Gray Yuan, I need you to do me a favor, according to Shimazaki Kananko's memory, the ceiling of your floor is actually a mezzanine space, I want you to sneak in there, use the vent of that warehouse, help me observe the situation inside the warehouse, of course, don't tell the three children about this. 】

It's a very dangerous move, but it's also a no-brainer.

In any case, he couldn't just sit back and wait for the police to come to the rescue.

If it was him who was in the north at this time, then Conan would definitely not hesitate to confirm the situation by himself, but now it was Gray Plains who was in the north leaves, and he could only choose to rely on her.

“……”

At the same time, in the North Leaf Building, Gray Yuan sighed softly after seeing this picture and text sent by Conan.

[I really can't help it......]

In an instant, she guessed the idea of a certain great detective, and although she could choose to refuse, the great detective would not force her to do it......

However, if there was no way before, it would have been forgotten, and now that she can help a little, she really can't just leave those people and turn around and leave......

Moreover, this is not a very dangerous thing, but it is just a matter of sneaking into the ceiling to observe the situation inside the warehouse, as long as she is careful, there will be no danger.

"Well, sure enough, there's still no signal......"

Thinking like this, Gray Yuan Ai put away his mobile phone, looked at the three little ones who were still squatting in the corner, thought about it for a while, and then said:

"It seems that we can only escape on our own now, but before that, I want to observe the situation outside, you stay here and wait for me, don't wander around, I will be back soon."

This kind of dangerous thing, even without Conan's reminder, she has to act alone.

"I—We're going too!" When the three little ones heard this, they immediately spoke.

"Nope." Gray Yuan Wai rejected them directly.

"But ......"

"Have you forgotten what I said again?" Hearing her words, the three of them immediately lowered their heads again.

"Okay, that's it, I'm just going out to have a look, you're all waiting for me here, do you hear?"

“…… Well. ”

After receiving a reluctant reply from the three of them, Gray Yuan Wai turned around and quietly left the stairwell.

[Ashbara, in the windowside corridor on the west side of your floor, there is a vent that is larger than the other vents because of the architectural error at that time, according to Shimazaki Kanako's memory, this vent should be in a corner of that corridor, you look for it. 】

The picture and text sent by Conan came from the software again, and Gray Yuan looked a little helpless when he saw this.

It's really going to make people callous, detective.

Leaving the stairwell, she took a closer look at the uninhabited hallway, and as Conan had said, cautiously came to the windowside hallway on the west side of the building.

The west side of the window on the north leaf corresponds to the direction of the West Leaf Building, because she was worried that she would be discovered by the terrorists of the West Leaf Building, she bent all the way, hid under the window and moved quickly, and found the corner that Conan said very smoothly.

This vent was indeed larger than the other vents in the building, as Conan said, and although it still couldn't be passed through by adults, at least it was enough for a child like her.

It's just that she suddenly found a problem.

[Detective, I can't reach this vent. 】
