Thermite underwater cutting is indeed the fastest underwater cutting method, but it is also the most violent cutting method.

This cutting method is usually used for cutting ultra-thick steel plates, because this method is simple and violent, so don't expect to use this cutting method to cut out any regular graphics.

For example, if the plasma arc cutting or arc-oxygen/steel cutting method is a rigorous meticulous painting, then this thermite cutting method belongs to the impressionist painting
However, using this method to break open the underwater door steel plate of the secret base is the most suitable.Yang Jing didn't want to cut the gate into any regular pattern, as long as the steel plate of the gate can be broken and people can get in, it's OK. It doesn't matter whether the broken hole is round or square.

With the cooperation of Yang Jing, George Cruise melted the 120 mm thick steel door into a large hole with a diameter of one and a half meters in less than half an hour.

The thickness of this steel door exceeded Yang Jing's estimation. A 120 mm thick steel plate was enough to serve as the frontal armor of a medium tank in World War II, but it was used here as a door, and it was such a large door. It is enough to witness the importance that Onishi Takijiro, who built this base at that time, attached to this base.

But Yang Jing estimated that the moment the gate was broken open, the sea water outside the gate did not flow into the gate. Obviously, there was also sea water inside the gate.

When Onishi Takijiro built this secret base, it was obvious that submarines were used to transfer and transport the property looted from various places into the base.After all, this kind of base hidden under water is the most hidden. More than 70 years ago, it was almost difficult for anyone to find it here.

Therefore, it is impossible for this kind of underwater base to completely block the water. It must be able to allow the submarine to dive smoothly and float up. Therefore, there should be a large pool inside the gate to facilitate the submarine to float up, and then transport the transported water. The property is shipped out.

Under such circumstances, George Cruise naturally couldn't follow in. Because there is air in this kind of submarine cave, the air floats on it, and the air pressure can resist the pressure of seawater, so water won't pour in.The kind of movies where people go into a cave like this and take off their diving suit instantly, that's pure nonsense.

The reason is very simple. Although seawater will not be poured into this kind of submarine cave, the pressure of the seawater in the cave is still very high. It seems that at this depth, George Bruce is actually bearing up to five atmospheres of pressure, and He has been breathing with scuba, because of the seawater pressure, the nitrogen in his body has already been decomposed into his blood by this time.

If he swims in and immediately goes ashore from the cave, takes off his diving suit, and is directly exposed to the same air pressure as the sea level, it means that he has reached the sea level instantly from a depth of 50 meters, and the blood in his blood Helium will rush out of the blood due to the rapid decrease in air pressure, eventually forming a large number of air bubbles in his lungs, and in severe cases it will directly burst his lungs!

This is known as decompression sickness.

Although it's not clear what's behind the gate, for safety's sake, it's best for George Bruce to slowly float up according to the regulations, so that the pressure in his body can gradually adapt to the smaller and smaller air pressure, so as to avoid The emergence of decompression sickness.

George waved his hand at Yang Jing and began to slowly float up. Clark McCann was still waiting for George at a depth of about 30 meters. The two of them would slowly float up together and finally return to the surface of the sea.

Yang Jing has energy body protection, so he naturally wouldn't worry that he would get decompression sickness, so after seeing George slowly rising up, he turned on the waterproof spotlights on the top of his head and shoulders. Drilled into the melted hole.

The quality of the sea water near the Mauge Islands is quite good. When I was cutting the gate outside, I didn’t even need to turn on the lights, because under this excellent sea water quality, the sunlight can even penetrate the sea water at a depth of more than 50 meters, allowing Yang Jing They can all see at this depth.

But it was completely dark inside the gate.

The powerful waterproof spotlights on the top of the head and shoulders can illuminate more than ten meters away even in the water. Compared with the occasional groups of tropical fish swimming freely outside the gate, it completely changes after entering the gate. It became a world of silence and darkness.

It is not surprising that there is not even a shadow of a fish behind the gate. Considering the degree of sealing of this gate, the seawater behind the gate may not communicate with the seawater outside for more than 70 years. How can there be fish?

Not long after swimming in, Yang Jing began to float up quickly. After floating up to about [-] meters, Yang Jing only felt light on his body, and his head and upper body were already out of the water.

The surroundings are still invisible, but the spotlights on the top of the head and on the shoulders can now directly illuminate a place three to forty meters away because there is no barrier from the sea water, so Yang Jing can easily see the light that is seven or eight away from him. The slipway made of reinforced concrete meters away.

The berth is about six or seven meters above the water surface. This height is just enough for the submarine to float up. The position of the bridge is level with the berth, which is convenient for cargo delivery.On the west side of the slipway, there is a ladder made of steel bars to climb up the slipway.

But Yang Jing was not in a hurry to step on the slipway, but continued to step on the water to keep his body balanced, and began to look around.

This submarine cave is obviously a huge cave formed naturally. It should have been formed when the magma erupted from the depths of the earth's crust was mixed with a large amount of gas during the volcanic eruption.

This situation is common in volcanoes, because when a volcano erupts, the huge heat will melt the rocks of the mountain body. At this time, once there is a large amount of gas, it will easily form in the soft mountain body. Huge void.And if the impact force of the gas is not enough to break through the magma, when the magma cools and forms rocks, the gas will be left in the mountain forever, forming such strange caves.

The huge cave in front of him was obviously formed in this way, after all, just a few meters away is the huge crater.

The top of this cave is 30 meters from the water surface. As for the length and width, Yang Jing can't see the end.However, in the middle of World War II, the main submarines of the Japanese Navy were all about 100 meters long. This large pool that can be used by submarines is at least more than 100 meters long.

The width of this large pool is about 15 meters, which is about the same as the width of the gate.The widest submarine of the Japanese army during World War II was the U142 submarine technology imported from the Germans, a first-class patrol submarine built by itself. This kind of submarine has the widest hull of 1970 tons (water)/2791 tons (underwater). Reaching 9.22 meters, it is the widest submarine among all the models of the Japanese army.

Therefore, the gate and pool with a width of 15 meters were enough for the widest Japanese submarine at that time to enter safely.

In this huge hollow, except that the berth is made of reinforced concrete, almost all of Yang Jing's sights are the most primitive rock walls.Obviously, this secret base was a natural cave that Onishi Takijiro accidentally discovered back then, and then slowly transformed into such a secret underwater base.
