How long has it been, and he still cares about hide-and-seek? Yuantai must be too nervous...
Conan sighed for a while, but he also knew that now was not the time to talk about this, so he calmly said:
"Don't worry about it for now. Wasn't there an earthquake just now? Were you not injured?"
"Oh... I'm not injured, but the cabinet I used to hide in almost turned over." Genta said.
That's good……
Conan breathed a sigh of relief: "Anyway, come to the first floor quickly. We have to get out of here quickly."
Here, Yuantai happened to stroll to a door and was still considering whether to hide inside. Hearing this, he said in surprise:
"Eh? But the game is not over yet."
"..."
Conan felt a little tired:
"Hey, maybe there will be aftershocks. If you want to play, go home and put down your schoolbag first, and then go to a park or something."
After an earthquake, the geological structures in some areas may become unstable. For safety reasons, you can choose a nearby environment such as a park or open space with a wide view to take refuge and observe.
For the five members of the Young Detective Team, the top priority is to leave this building that is in disrepair and is scheduled for demolition as soon as possible.
"Okay then..." Genta muttered, "But when the time comes, Conan, you will still have to be a 'ghost'."
"I know." Conan agreed.
At the same time, a slow and rhythmic knocking sound suddenly came from the corridor.
Yuanta was startled and turned around hurriedly to look at the corner at the other end.
It happened to be noon, and the sun's rays shone slantly into the room, hiding that area in shadow.
"H-Hey...Conan...it seems there are other people in this building..."
"Eh?" Conan was startled: "Did you see something?"
"No, I heard a sound like something banging on the wall."
Yuantai took a few steps in that direction and added: "It's not far from me. I just can't tell whether it's upstairs or downstairs."
It's possible that the earthquake damaged something in the building... Conan made a preliminary judgment and continued to ask:
"Is that sound always going on?"
"No……"
Yuantai recalled briefly: "At first, I heard 2 sounds, then 5 sounds, and then 2 more sounds and then stopped."
252? This is the call code for the Tokyo Fire Department, bad! Someone was trapped inside because of the earthquake just now...
Conan immediately took action and ran towards Genta's floor.
The other three followed soon after.
In the process of climbing the stairs, Mitsuhiko asked Ayumi, who was completely ignorant, about this aspect of science.
To put it simply, in a disaster-stricken area, once trapped in a collapse, shouting will not only consume physical strength and body moisture, but also make it difficult for the sound to accurately convey useful information due to coverings such as cement boards. .
Therefore, similar signal codes, in addition to 252 indicating the need for rescue, there are also codes 254 for people to wait for a while, 554 for calling the police, etc...
The four found Yuantai to meet up.
After some questioning, Yuantai said that except for the previous 252, during the period when they came here, there was no similar knocking sound in the building.
"It seems that if we want to find out the source of the sound, we can only investigate one by one." Mitsuhiko glanced at the row of rooms in the corridor.
At this time, the banging sound echoed again.
Conan was shocked and strode to the stairs.
"It lasted so long." Yuantai looked up in confusion.
"And it's not 252..."
Mitsuhiko silently counted the tapping rhythm and could confirm that there was no obvious gap in between.
Conan continued to lead the way: "I can only go up and have a look. You guys remember to stay behind me."
The five people climbed up another flight of stairs.
The banging sound became more and more obvious.
You can confirm the first room just around the corner.
Conan cautiously turned the doorknob, pushed the door open, and saw two uniformed staff, one fat and one thin.
At this time, the thin man was holding a hammer and hammering on the load-bearing wall of the room.
Noticed 5 of them.
The thin man stopped tapping and said in a stern tone:
"Hey! How could you run into an abandoned building and play?"
If it were an ordinary child, he would definitely be frightened by the scolding, and then run away without looking back.
But it's a pity.
Conan not only refused to accept this, but walked into the room with his hands in his pockets:
"Uncle, what are you doing?"
"We're going to hit the wall to test the hardness before demolishing the building."
As the thin man spoke, he took the hammer and chiseled it a few more times.
"He likes to play to the rhythm of pop music when he's happy." The fat man explained from the side.
"What, it turns out it was just a coincidence." Mitsuhiko and Genta were convinced.
Conan looked at the wall coverings that kept falling on the floor and the shopping bags from the convenience store not far away. He walked over to check and soon found something new.
The lunch boxes are all empty...
He asked while the two were discussing how to go to other rooms to test the hardness of the walls:
"Uncle, are there only two of you here?"
"ah?"
"Oh, yes……"
The two people's minds were obviously not on this matter, and their answers were very perfunctory.
Conan didn't give up. He took the opportunity and took the receipt in the shopping bag and asked:
"But - this is the bento you just bought at noon today, right? It says that all three portions have been eaten."
This kid...
The thin man frowned and explained along with the topic: "It's this guy. He can eat two lunch boxes by himself."
"That's right," the fat man patted his belly and agreed, "I finished the lunch for two in a matter of seconds."
The thin man no longer looked at Conan, but looked at the other four people standing outside the door and asked:
"Children, how are you if you weren't affected by the earthquake that just happened?"
"Um."
"We didn't suffer any injuries."
"And the earthquakes stopped immediately."
Ayumi, Mitsuhiko and Genta each answered one sentence at a time.
"That's it." The thin man responded: "Then you should go home quickly and don't let your parents worry."
His tone was no longer as harsh as it was at first.
No need to be scolded, Ayumi, Mitsuhiko and Genta were very cooperative and wanted to leave.
Conan moved to the door lazily. He already had the answer in his mind but still habitually collected more clues. He turned around and asked:
"By the way, uncle, can I ask another question?"
"Um?"
The two of them were alert and stared at the detective boy.
Conan said bluntly: "Approximately how much explosives will be used to demolish this building?"
