Conan: The Mechanic

The person with the gasoline barrel, heading towards them? This doesn't seem like a good call... If Chiba puts herself in the perspective of a villain, what can be done with so many gasoline cans is too frustrating.

"Uh..." A more subtle expression appeared on Qianyu's face.

No... No... I must find a way to find an interface that can say that I am aware of the other party's trace...

"Did you smell any gasoline?" Chiyu asked after taking a deep breath. "It's the kind of gasoline that burns."

"No, are you sure your nose is correct?" Officer Shiratori sniffed carefully and asked Conan in a very determined tone. "I ask myself if my nose is still in the more sensitive group."

"Gasoline?" Pu Si Qinglan gave a positive answer. "That said, I seem to have seen some gasoline smell on the people who came with me... wait, if you really smell something like this, doesn't it mean that the other side might be- no Ah, if I die, how are they going to get the money I haven't paid them yet?"

"By the way, you said there were collaborators," Officer Nakamori asked sharply. "How many are they?"

"A lot of them were initiated by the survivor back then, the descendants of the martyrs," Pu Siqinglan bowed and turned into a kneeling posture under the watchful eye of the crowd. "The eldest may be in his 80s or 90s, but the person in charge is a middle-aged man in his fifties. Maybe it's because the old man has run out of energy? I made an agreement with them that everyone will get what they need and everything will be done. After that, I will pay them two million yen as a reward, and they probably won’t plan to burn the gold master who gave them the money, so they get nothing in the end, right?”

"Actually, I didn't want to make any comments, but I still have to say that you are too naive, miss." The phantom thief Kidd, who released a pigeon, interjected. "If you just talk about treasures, there are too many good things in this castle - as you said before, many of the secret spaces here are well known to those in the engineering team. So no matter what Mr. Kasaka Kiichi Designing those ingenious mechanisms, they can use the stupidest method to use the internal money as a possession: for example, directly prying out the safe and taking it away, or shooting the safe with live ammunition, breaking the lock and the like. As long as you take half the contents of a safe in this way, it will be enough to recover the lost commission for your death, right?"

"This..." Pu Si Qinglan, who was awakened by the thief Kidd, didn't look good.

"You are very good at fighting, and your marksmanship is very good," Kaitou Kid sighed. "But seriously, you're still a little too naive to deal with people who are scheming."

While they were having such a conversation, Chiba stood on the spot and was making calculations.

In the standard fire model of a pool with a diameter of more than 2 meters, the burning speed of gasoline will be basically stable at a depth of 3.6 mm per minute, and the ignition point is 100 meters away from here (if Chiba intends to start, it can be before the other party reaches this distance line. Ready) means it takes a fair amount of time to flow over. In other words, if Chiba figured out some way to do it first when they were about to dump the gasoline and burn everyone to death—

In principle, it is feasible. The reconnaissance instrument he flew before (the flying action he made when he exposed Kidd) was electric. If the gasoline was dumped and slammed into it, the working electric components should be short-circuited in the gasoline. cause burning.

As for whether the gasoline burning will hurt them... If six people grab the gasoline barrel and dump it at the same time, the oil output per second should be 2-3 kilograms, which is similar to a gasoline belt of 3 mm * 100 meters * 1 cm. In the case of sufficient oxygen, the burning speed of a pool of gasoline is about 3.6 millimeters per second, which means that if the gasoline is ignited at a distance of 100 meters from them, they will not be able to burn the gasoline and the flame no matter how they dump the gasoline barrel. Go near the dungeon, because the gasoline burns out before it reaches them.

When did you become so cruel? After finishing the calculation, Qian Yu was tangled in a self-deprecating manner.

But it wasn't him who was the most ruthless, because next he saw the phantom thief Kidd beside him act even more frantically and directly.

"..." When Chiba's reconnaissance instrument observed the pigeons released by Kaitou Kid, Kaitou Kid glanced in the direction of his right ear, and then showed a rather dignified expression. A few seconds later, he released the second pigeon, which had a strap with two vials attached to its leg.

The bottle looked very thin, and the straps didn't look strong. It seemed that the pigeons only needed to shake the body a little to throw the straps away from their legs. And if the straps are thrown on the ground, the two bottles will inevitably shatter, and then they will react as they should when they are close to each other, such as... Boom?

"???" Qianyu stared at the figure of the second pigeon and disappeared at the door of the underground palace gate, and then turned her gaze back to the phantom thief Kid, only to find that the other side was also looking at her with interest.

"Forget it, I think we'd better find a way to get out of here without going through the secret passage." In the end, Kidd gave up looking at each other, but reminded everyone of the current top priority. "Also said, her collaborator is on the top. Maybe everyone has a gun now, waiting for us to go up one by one. It's better for us to go out in another way."

"Is there really a second way in this kind of place?" Xiao Lan was worried. "After all, it's a secret way. If there is another way, wouldn't it be easy to invade from the outside world?"

"But in other words, if there is no other way, it means that once the opponent occupies the castle, it can easily seal the occupants inside, leaving no room for the defender to turn around." Fei Yingli reminded her daughter. "After all, this is the castle where the royal family once lived for a long time, and the secret passage must be developed enough. In other words, if there are multiple secret passages, I don't find it strange at all~www.readwn.com~ I am outside. It has been checked carefully, only this door has not been checked in detail." Kaitou Kid spread his hands. "Don't look at me, I haven't been able to solve the puzzle of the gate like you, so naturally I have no chance to come in. But at least from the outside inspection, I can guarantee that there is no potential secret passage. If this underground fortification group has access If you go to the secret passage outside, it must be here."

"As evidence, Miss Pu Siqinglan also said that 32 of 33 people were burned to death, and the person who was not killed still had such an organ set up in the underground palace, right?" Qian Yu added. "33 people were burned in the passage, but only 32 died, and one person survived, indicating that there is a place to escape the fire. And the arrangement of its own organs in the underground palace means that you can freely obtain props. The two phases are superimposed, and the most likely situation is to escape from some escape channel in the secret passage, and then slip back through this passage."

"Thousand feathers," Kaitou Kid suddenly ordered. "Go and close the gate of the underground palace."

Qianyu raised her eyebrows, and then showed a surprised expression that seemed to have seen something very visually striking.

With such amazement, Qianyu came to the wall and pressed the button to close the gate of the underground palace.

"Goo~~~Goo~~~" A few seconds later, the two doves released by Kidd flew in through the gap at the bottom of the underground palace, and the gate of the underground palace closed again.

At the last moment before closing, Chiyu seemed to see a ray of fire coming from the other side of the gap.

Remark:

Pool fire burning rate data - "Research on the combustion characteristics of oil pool fire under free combustion" by Shanghai Fire Research Institute of the Ministry of Public Security, when the diameter of the oil pool is less than 2 meters, the burning rate is lower than the stable value.
