The seaplane stayed on the sea about 300 meters away from the southern end of the lagoon of the Maug Islands, George placed the C4, and after it took more than 20 minutes to rise to the surface, Yang Jing and the four of them took two motorboats to the seaplane.Here, George, who had changed out of his diving suit, personally pressed the detonation button, and the next moment nothing happened at a depth of fifty meters underwater, it was not the kind of deep-water bomb explosion that would make people on the surface feel it, this small yield of C4 was detonated, and people on the surface of the water could not feel any vibration and sound at all.Yang Jing and his party waited on the water for more than half an hour, and after making sure that the volcano had nothing to do, they returned to the lagoon again.This depth is the only one he can quickly ascend and dive, and Chris and they can't be elite.In order not to delay time, Yang Jing had to act as an old scalper again and personally put on the battle.A hole about two meters in diameter has appeared at the site of the underwater blasting, and the rock layer about one meter thick has been stripped away by C4, revealing the steel plate inside.Similar to Yang Jing's guess, the entrance to this secret base is one or two steel gates, but in order to cover up the existence of the entrance, there is a layer of rock about one meter thick attached to the outside of this gate, only because the gate is opened and closed horizontally or up and down, so this layer of attached rock also needs to be indented with the gate into the surrounding rock layer, so this piece of rock wall will be so flat.The rock wall in the lower left corner of the gate had been completely blown open, revealing the steel gate inside.Yang Jing took out a hammer and struck the exposed steel plate of the gate, judging from the sound it made, the thickness of the gate exceeded ten centimeters.Such a heavy gate, and it is very likely that it was made of special steel, was able to be immersed in seawater for more than 70 years without being completely corroded by seawater.Although Yang Jing is the best at dealing with this kind of gate, there is storage space, and there is no gate in this world that can stump Yang Jing, but Yang Jing can't do this, and there are a few bodyguards behind him.The door opened with storage space is absolutely different, anyone who sees that kind of trace, can know that there is a huge cat in it, Yang Jing doesn't want to expose the secret of the space, so he can only take the most primitive way to break this piece of steel plate.After Yang Jing floated up, he explained the situation, and several bodyguards began to discuss how to break down the door, which was at least ten centimeters thick.For this kind of thing, Yang Jing is a complete layman, he can only provide the situation of this gate, as for how to break the gate, he can only listen to Chris and discuss there.John Bruno says: "Let's cut with an oxygen-hydrogen cutting lance, which has an optimal vapor pressure for combustible gas, is easy to maintain the flame, and is lightweight, allowing it to cut to a depth of about 100 meters.This time we need to cut to a depth of only more than 50 meters, and it is completely possible to break through this gate in this way, and we also brought this equipment this time. ”Chris shook his head and said, "John, your method is good, but the cutting speed of this method is too slow. ”Kevin Martin also said: "Yes, we can't stay underwater for too long, we need to break down this door as soon as possible."
The most important thing is that this oxygen-hydrogen cutting method can deal with general ferrite materials, but it seems to be a bit insufficient to deal with the gate made of this special steel.And don't forget what the boss said just now, the thickness of this door is at least 100 mm or more, and the oxygen-hydrogen cutting method cannot deal with such a thick special steel plate. ”John shook his head and said, "With such a thick special steel plate, I think even if it is cut with an arc-oxygen steel pipe cutting strip, I'm afraid it won't be able to cut it." ”Several people nodded silently, and George Bruce on the side looked at everyone with a smile, and then said to Yang Jing: "Boss, I have two ways to break the steel plate of this steel door here." ”As soon as several people heard this, they all looked at George.Several of them didn't come up with a solution, this guy actually has a way, and he said that it was two.George shrugged his shoulders and said, "Actually, it's not that hard to break the steel plate of this steel door.I don't know if you've heard of the underwater formed charge explosion method?
To put it bluntly, this method is to use the power of directional medicine to directly blast the steel plate, and the use of this method can cut pipes, cable I-beams, cut holes, special steel, etc., and the cutting thickness can exceed 100 mm.However, this method is more violent, and it is easy to cause damage to the components near the cutting point. ”Yang Jin nodded thoughtfully and said: "It doesn't matter if the nearby components are destroyed, anyway, I don't know how long this base has not been activated, and if it is blown up, it will be blown up."
It's just that we have this off-the-shelf equipment now?
”George shook his head with his hands outstretched, "Boss, we don't have this kind of equipment ready.However, this kind of equipment is very simple, and it can be easily purchased on the market, so let's fly back to Saipan first and buy it back and then break it. ”Yang Jing shook his head slightly and didn't make a sound, Chris said, "George, didn't you say that there are two ways?"
What's the other way?
”"That method is more violent than this method, which is to use the special thermite to forcibly melt this steel plate."
When everyone heard this, they couldn't help but gasp, they were all retired soldiers, so they naturally knew the power of this thermite.Thermite is a mixture of aluminum powder and refractory metal oxide, ignited with an ignition agent when used, the reaction is carried out violently, alumina and elemental iron are obtained and a large amount of heat is released, the temperature can reach a terrifying 2500 degrees Celsius, and almost most of the metal or alloy steel can be melted.It is said that it is most appropriate to use thermite to melt this special steel plate, but if thermite is applied in water, it will decompose into oxygen and hydrogen due to the high heat generated, and once these two products are mixed and ignited, it will cause an explosion.Chris expressed this concern, but George shook his head with a smile and said: "This is not a problem, I have several thermite formulas that can be cut underwater, as long as you are careful, it will not cause an explosion." ”After a pause, he continued: "In fact, since the invention of thermite, various thermite formulations have been developed accordingly to cope with different welding or cutting environments, as early as more than 30 years ago, this underwater thermite cutting method has appeared, and now it is very mature, so you don't have to worry.The main thing is that the speed of breaking the steel plate with this method is the fastest. ”Yang Jing nodded, "George, if you're sure, then use this cutting method."
On the premise of ensuring safety, use this method to break the damn steel plate!
”George smiled and nodded, "Don't worry, boss, I promise you'll be able to enter that damn secret base before evening comes!"
