Starting from Zero

This bomb was made temporarily, so it was in a hurry, so many things used substitutes, such as this air pressure sensor. The real air pressure sensor is actually quite a complicated thing, but the stuff used on this device is actually simply not a pressure sensor.

This so-called air pressure sensor is actually an air cylinder similar to a syringe needle, but its inside is vacuum. Because the inside of the oil drum has always been in a vacuum state, the inner vacuum cylinder will not have any reaction. However, once the oil drum is depressurized, the cylinder is affected by the outside atmospheric pressure, and its external piston will be quickly pressed into the vacuum cylinder. internal. There are two copper sheets at the bottom of the vacuum cylinder, and there is a gap between them, so that they are not connected, that is, they are not energized. This state means that the surrounding is still a vacuum environment. The bottom of the piston is covered with a layer of copper. Once the external air pressure is restored, the piston will be pressed into the bottom of the cylinder, and then the copper will contact the two copper contacts at the bottom of the cylinder at the same time, so that the circuit is connected. . Once the circuit is connected, the air pressure is restored and the bomb detonates.

This design is very simple, but quite terrible, because the air pressure recovery speed is very fast, and the piston is super sensitive, so as long as the average person opens the oil drum, it will inevitably cause an explosion. But now the frost and snow have sealed the top of the drum, so even if the lid is opened, air still cannot enter the inside of the drum, so the air pressure trigger will not activate. As for dismantling it... this is the easiest. Just pull out the piston.

After the barometer was gone, Frost scanned it again, confirming that there was only one barometer, and then removed the ice on the surface.

After the air pressure was restored, the bomb did not explode because the barometer was no longer working. Now that the shell of the bomb has basically failed, we confidently and boldly cut the entire outer wall of the oil barrel directly, leaving the bomb completely exposed in front of us.

Intuitively, the structure of this bomb is quite complicated. There are very sophisticated pipe structures on the outside, and these pipes are the main design that prevents you from removing wires.

The other party actually stuffed the bomb into a set of pipelines. In addition to the outside barometer, the inside of this pipe is filled with something similar to grease. This thing does not conduct electricity, and can play a role in shielding electromagnetic fields and heat dissipation.

All the lines used by the bombs are sealed in this pipeline, and the grease filling inside the pipeline is the second insurance, because once we open the pipeline, the oil pressure inside the pipeline disappears. Without oil pressure, the bomb will be immediately detonated by a trigger device. Therefore, this grease-filled pipe is also a tamper-proof design.

Of course, we are not going to dismantle the pipeline, but want to directly attack the bomb itself.

Because the magnetic field shielding device has failed, now it is impossible to completely shield our electromagnetic induction ability by relying solely on the shielding of the grease itself. Further scanning of the interior can confirm that the internal detonator of the bomb is ultimately connected to the four batteries.

Modern bombs, as long as they are not ignited on the spot, they must be detonated electrically. In fact, modern high-end explosives are quite safe. Many military explosives will not be detonated even if they are thrown into the fire. They must be detonated with an electric arc generated by a strong current, reaching a high temperature of several thousand degrees in an instant.

This kind of design has many advantages, the biggest advantage is safety, it will blow up without being unfathomable mystery. However, their shortcomings are very uniform, that is, they need electric current to detonate.

It does not require too much current to detonate a bomb. A coin battery the size of a dollar coin is enough to detonate the most primary level of explosive, and then the tandem detonation method using explosives to detonate the explosive can detonate anything. Specifications of explosives.

The internal structure of this bomb is more complicated, so it uses four sets of batteries, one of which is the main battery, which is directly a lead-acid battery for a car. The other three batteries are all the same lithium batteries, which appear to have been removed from some kind of remote control. After all, this kind of battery with both positive and negative poles on one side is a special battery, which is not very common.

The solution we thought of to solve this bomb lies in these four batteries.

There are too many protection designs on the bomb, and it will take too long for us to crack them one by one. And the enemies around are not in a daze, they have already begun to attack us. It's just that the electromagnetic barrier formed by Jingjing and the small dragon girl protects us, so the bullet can't threaten us temporarily. However, it would not last long to carry the opponent's attack like this. After all, those outside were not miscellaneous soldiers, and their equipment was terribly good.

Because we are in a hurry, we need a simple and direct way to solve this bomb, so the final solution we thought of was to steal electricity.

No matter how complicated the bomb is, it must require electricity to explode the bomb. Even for a nuclear bomb, the initial detonation part requires electricity. There are no mechanical nuclear bombs, but at least this is not. What we need to do is to drain all the batteries that can be discharged inside the device. As long as the battery is dead, no matter how many detonating devices we trigger, the bomb will not detonate because there is no current to detonate the bomb.

The reason why we plan to steal electricity instead of cutting the wires is mainly because there is oil pressure in the pipelines in series. We are impossible to react faster than the current, so it will inevitably cause a bomb before cutting off the current. Detonate. In addition, this bomb has several lines. If they cannot be cut off at the same time, there is no guarantee that the bomb will not explode. Even though our Dragon Clan is fast and the behavior can be synchronized, this synchronization is only a superficial synchronization, and there must be some gaps in the subtleties. These wires must be cut off synchronously to ensure that the bomb will not be detonated, and the interval between errors cannot be less than the time for the current in the bomb's circuit to go through the entire loop. The speed of electricity is the same as the speed of light. The total length of the lines in this bomb plus one piece will not exceed one hundred meters. You can imagine how long it takes for the current to complete this distance. Obviously, we cannot cut off all the lines at the same time in such a short time, so this method is not feasible.

However, it is not possible to reduce the wires simultaneously, but it is possible to steal electricity.

There is no voltage detection system in this bomb, so if we discharge the battery, the bomb itself will not respond when the voltage drops gradually. When the voltage drops until the voltage stabilizing capacitor can no longer maintain a stable voltage When outputting, the detonating device of the bomb may indeed be connected to the detonating line, but when the time comes, the remaining power in the battery is no longer enough to detonate the bomb. In this way, this bomb is tantamount to being completely scrapped.
