This bomb was made temporarily, so it was very rushing. Therefore, many things are used as substitutes, such as this air pressure sensor.￥f, a real air pressure sensor is actually quite complicated, but the thing used on this device is actually not considered an air pressure sensor at all.

This so-called air pressure sensor is actually an air cylinder similar to a syringe needle tube, but its interior is vacuum. Because the oil drum has been in a vacuum state before, the air cylinder with an internal vacuum will not react at all. However, once the oil drum is relieved, the air cylinder will be affected by the external atmospheric pressure, and the external piston will be quickly pressed into the inside of the vacuum cylinder. There are two copper plates at the bottom of the vacuum cylinder, and there is a gap between them, so that the two are not connected, which means they are not powered on. This state means that there is still a vacuum environment around. The bottom of the piston is covered with a layer of copper plate. Once the external air pressure is restored, the piston will be pressed into the bottom of the air cylinder, and the copper plate will contact the two copper contact plates at the bottom of the air cylinder at the same time, so that the circuit is turned on. Once the circuit is turned on, it indicates that the air pressure is restored, and the bomb detonates.

This design is very simple, but it is quite fatal, because the air pressure recovery speed is very fast and the piston is super sensitive. Therefore, as long as the oil barrel is opened, it will inevitably cause an explosion. However, now the frost and snow have sealed the top of the oil barrel, so even if the lid is opened, the air still cannot enter the inside of the oil barrel, so that the air pressure trigger will not start. As for removing it... this is the easiest. Just unplug the piston.

After losing the barometer, Frost and Xue scanned it again with concern and confirmed that there was only one barometer, and then the ice layer on the surface was removed.

After the air pressure was restored, the bomb did not explode because the barometer was no longer working. Now the shell of the bomb has basically failed. We confidently and boldly cut open the entire outer wall of the oil barrel, allowing the bomb to be completely exposed to us.

It looks intuitively. The structure of this bomb is quite complex, with very precise pipe structures outside, and these pipes are the main design that prevents you from dismantling the wires.

The other party actually stuffed the bomb into a set of pipes. In addition to the barometer outside, the pipe was filled with something similar to grease. This thing is not conductive and can shield the electromagnetic field and dissipate heat.

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

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

Because the magnetic field shielding device has failed, it is now impossible to completely block our electromagnetic induction capabilities by just the obstruction of the grease itself. Further scanning the internals can be confirmed that the internal detonation device of the bomb is ultimately connected to the four batteries.

Modern bombs, as long as they are not ignited on the spot, they will inevitably be electric detonation. In fact, modern high-end explosives are quite safe. Many military explosives will not be detonated even if they are thrown into a fire. They must use arcs generated by strong currents to reach a high temperature of several thousand degrees in an instant to detonate such bombs.

This design has many advantages, and its biggest advantage is safety and will not explode inexplicably. However, their disadvantage is that it requires current to detonate.

It does not take too much current to detonate a bomb. A button battery as small as a one-yuan coin is enough to detonate the primary explosives. Then, the tandem detonation method of explosives can be used to detonate any specification of explosives.

The internal structure of this bomb is relatively complex, so four sets of batteries are used. One of them is the main battery, which is directly a lead-acid battery for automobiles. The other three batteries are all the same lithium batteries, which seem to be removed from some kind of remote control. After all, this kind of battery with both positive and negative electrodes on one side is a special battery, which is not very common.

The solution we thought of was on these four batteries.

There are too many protection designs on the bombs, and it will take too long to crack them one by one. Moreover, the enemies around them are not dazed. They have already started to attack us. However, because the electromagnetic barrier formed by Jingjing and Xiaolongnu protects us, the bullets cannot threaten us for the time being. However, it will not last long to withstand the opponent's attacks like this. After all, those outside are not miscellaneous soldiers, and their equipment is very good.

Because we are in a hurry, we need a simple and direct way to solve this bomb. So the ultimate solution we think of is stealing electricity.

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

The reason why we plan to steal electricity instead of cutting the wires is mainly because there is oil pressure sealing in the series pipeline. It is impossible for us to react faster than the current with one knife, so it will inevitably lead to the bomb detonation before cutting off the current. In addition, this bomb has several lines, and if it cannot be cut off at the same time, it cannot be guaranteed that the bomb will not detonate. Even if our dragon clan is very fast and its behavior can be synchronized, this synchronization is only the synchronization on the surface, and there must be some gaps in the subtleties. These wires must be cut off simultaneously to ensure that the bomb will not be detonated. The error interval in the middle cannot be lower than the time when the current in the circuit in the bomb goes through the complete circuit. The speed of electricity is the same as the speed of light. The total length of the line in the bomb will not exceed one hundred meters. You can imagine how long it takes for the current to complete this distance. We obviously cannot cut off all lines at the same time within such a time, so this method is not feasible.

However, synchronous reduction of wires is not possible, but stealing electricity is OK.
