"Find the trigger first, huh...... Do you know what a trigger looks like? It's just a gray plastic ......."

Inside the Tokyo Tower, Conan is defusing a bomb under the teachings of Uncle Bomb Disposal Ban.

"I found it, I've seen the construction of the trigger on TV. Conan interrupted, he was now talking to the expert with the flashlight he had just sent down in his mouth, and he kept fiddling with the bomb in his hand, and he had already cut six or seven wires, as for the expert guidance? Conan, who had learned almost everything in the world in Hawaii, said that he couldn't see his progress on it anyway.

The bomb is a very delicate thing, why do you cut so many wires, as long as you don't understand the last two lines, should they explode or explode at a timed explosion? What are so many threads cut before?

In fact, the structure of a time bomb can be very simple, a detonator is buried in the explosive, two wires are connected to the battery box, and a timer switch is placed in the middle, even if it is clockwork, and if it doesn't kill, it doesn't matter if the bomb is kicked as a ball, as long as it is not a flame foot, it is easy to kick and not explode.

But such a bomb is easy to dismantle, you can cut the wires as soon as you cut them.

In order to prevent the bomb from being easily dismantled, the bomber also had to add some insurance.

For example, in this bomb, in order to deal with the means of directly removing the battery, the bomber designed the battery box as a metal box and a metal cover, and at the same time connected to another circuit, if the cover was taken off and the circuit became a short circuit, there was a logic switch to detonate the bomb in advance, that is, to form a "device to prevent the battery box from being destroyed." ”

In order to prevent the "device from being destroyed by the battery box", the bomber also had to design a "device to prevent the destruction of the device from preventing the destruction of the battery box", and then continue to add the next level of the "...... prevention" device until the bomber himself could not see which wire was the last level, and this aspect was completed.

Then, in order to prevent the battery box from being shorted directly, the bomber installed a coil in the circuit, and if the current in the circuit changed, it would detonate.

For example, in order to prevent the gunpowder from being directly separated from the detonator, the bomber welded a sturdy metal box, and if you want to use the gunpowder, you have to disassemble the bomb and take out the gunpowder.

In the same way, other parts such as timers and wires are also protected layer by layer, so if you want to defuse the bomb, you have to repeatedly cut the wires that will not affect the normal detonation of the bomb at all.

In fact, the general processing mode of this kind of neuropathic bomb is to transport it to a deserted wilderness where no one is around, and it is directly detonated by the police on the spot, only like the kind of bomb that Conan encountered that is stuck in the elevator shaft, and there is a mercury rod that cannot be easily moved, it needs to be dismantled a little bit, and this kind of bomb specially designed to be dismantled is actually only a few, and the structural design of more bombs is actually very simple, after all, this thing is made to blow things up, not to be dismantled for the police to play.

As the experts above chattered, Conan cut another thread, and seven eighths of the way had been dismantled, and at this time the bomb triggered a program hidden in the bomb, and a line of words began to appear on the display screen that originally only had a countdown.

"Brave policeman, I want to praise you for your courage and praise you, but you can't let that make you relieved. I've also hidden two other bombs, both in a crowded ant-colony area, and 3 seconds before the bomb explodes, I'll show you a hint telling you the location of another, even greater, fireworks celebrating the end of the game, may you fight tirelessly, Gui'an. Conan reads, but he keeps holding his phone in his hand.

"Conan...... What are you talking about?" Takagi, who was waiting in the elevator, had a hint of foreboding when he heard Conan's words.

"Officer Takagi, we won the lottery. A tremor sounded in Conan's voice, reaching the ears of Takagi and the bomber.

"I see, I heard that it was the same situation four years ago. Takagi took a deep breath and said.

"Is there going to be a repeat?" asked Conan, who was said to have come four years ago.

"But the water ......," Takagi wanted to ask, didn't he mean that the Mizuma Police Department found a bomb last night?

"It says that there are two dense bombs, how many people will it be, how many times will it be two?" Conan's words sounded to the ears of the bomber as if a child was doing the psychological work of a police officer, and let the police officer who was afraid of death die with him.

However, Takagi heard that Conan was telling himself to pay attention to the fact that there were two bombs, and so far only Mizuma had found one, which meant that the other had not been found.

Takagi's expression changed, and he hurriedly called to convey the matter to the outside, he didn't dare to make his own decision if he needed instructions from above.

"What's wrong with you?" Miwako Sato looked at Mizuma curiously, why did she suddenly change her face after sending and receiving two text messages.

"Just now, the bomb defuser at Tokyo Tower sent me a text message, after all, the bomb was repackaged, and he asked me what the situation of the bomb is now, can it explode?" ”

"And ...... your expression?"

"The bomb appeared the same as four years ago, and the text said there were still bombs, but it said that there were two more. Mizuma said with a gloomy face.

Since we are talking about two, and there are a total of four bombs in Didan High School, the two bombs must refer to two different places.

In fact, it can be imagined that the butterfly effect appeared, and four years ago, because Mizuma found another bomb, he almost saved Matsuda Jinpei, who was originally going to die, and the bomber probably installed two bombs in order to prevent it.

And since it is to prevent other bombs from being found first, the so-called second bomb should not actually exist, otherwise there is a chance that it will be found no matter how many are arranged.

But Mizuma remembered the 100 grams of explosives, because he didn't dare to deny the existence of the second bomb.
