C4 can almost be regarded as the special explosive for American soldiers. No matter in real battles or in those American blockbusters, as long as there are explosion scenes, this highly explosive that can be molded at will will make a grand appearance.

Of course, given the power of this thing, there is almost nothing that cannot be dealt with in the movie.

To paraphrase a line from a martial arts novel - just a light press, and everything turns to ashes...

Although C4 is very powerful, this explosive is absolutely safe. It can only be detonated by a detonator, whether it is an old-fashioned fuse detonator or an advanced electronic detonator. As long as it is a detonator, it will be fine. Without a detonator, C4 will basically not be detonated.

C4 will not explode even if you shoot it with bullets; even during the Vietnam War, American soldiers often ignited C4 to keep themselves warm - after ignition, this thing is like gas, it will only burn but not explode...

Therefore, something like this, which is safe, powerful, and can be used as fuel for heating or even cooking anytime and anywhere, must be the favorite of retired soldiers like Chris. It is also the best choice for killing and arson at home, traveling, and so on!

Looking at George Bruce, who appears to be quiet on the outside but is actually a violent man at heart, Yang Jing could only smile bitterly helplessly.

"George, is this thing reliable? I mean, we have to detonate it fifty meters below the water surface. Can we detonate it at such a deep place? Another thing is that this is a crater. Although it has not erupted for a long time, the volcano under our buttocks is an intermittent active volcano. If this thing explodes below, don't detonate this volcano, it will be a lot of fun..."

The tall and strong Clark was not only the firepower man in Chris's team, but also occasionally acted as a demolition man. He was very familiar with this kind of work.

"Boss, don't worry about this. C4 can be safely detonated under fifty meters of water. As for detonating the entire volcano, boss, you think too highly of C4. We only have so little C4, not even enough to tickle this volcano, how can we possibly make this big guy lose his temper? Don't worry, since George has said this, he must be fully confident that it will be safe."

George smiled but said nothing, but his expression was full of confidence. When he was in the Delta Force, this guy was the vehicle driver and demolition expert in Chris's team. He was very good at using C4. Yang Jing once talked about George with John Bruno. John Bruno admired George's talent in demolition very much, and John also did something that sounded a little incredible.

When John and his team were on the battlefield in Afghanistan, George once made a bet with the chief demolitionist of the 426th Forward Support Battalion under the 101st Airborne Division in his free time. As a result, in that bet, George used C4 to accurately smash a 60-kilogram rock into pieces from the bottom, but a porcelain plate for eating placed on the stone was safe and sound.

This kind of control is even more amazing than cutting meat from a balloon, and it makes the chief demolitionist of the 426th Forward Support Battalion feel inferior. You have to know that the 101st Airborne Division is one of the most elite troops in the United States, and the 426th Forward Support Battalion directly under the division headquarters is recognized as the elite of the 101st Airborne Division. The chief demolitionist of this elite among the elite troops is inferior to him in terms of demolition, which is enough to prove George's awesomeness.

"Okay, George, you win. But you have to be 50 meters underwater to place the explosives. When you come up after placing the explosives, you must pay attention to your ascent speed. Don't get decompression sickness because of this. Otherwise, I would rather not use explosives to blow up this damn rock wall."

George said seriously, "Boss, don't worry. When I was on a mission in the army before, I once performed a blasting mission at a depth of more than 80 meters. A depth of 50 meters is no problem."

"Well, then you just need to be careful. Clark, you wait for George at a depth of thirty meters. Keep an eye on him and don't float up too quickly."

Several people started to laugh.

While George was changing into his diving suit, Yang Jing said, "Don't use too much medicine. I suspect there is a steel plate or something behind this layer of rock. The outer layer of rock should be used for cover-up. Although it is one meter thick, we only need to blow down these rocks."

George put on the compressed air bottle with the help of Klak and said, "Don't worry, Boss. I'll go down and take a look at the specific situation. I'll place the medicine according to the actual situation."

Because George has to dive to a depth of fifty meters and stay underwater for a long time, he cannot use the free diving method like Yang Jing. Yang Jing has energy protection and can ignore the diving depth of fifty or sixty meters, but George can't. He needs to wear a proper deep-diving dry diving suit and a huge compressed air bottle to ensure that he has enough air to stay underwater for a long time.

After everything was ready, four people led by Yang Jing went into the water, and the remaining five bodyguards, led by Chris, drove the seaplane out of the lagoon.

Safety first, no one can guarantee that the explosives will not detonate the volcano.

Under Yang Jing's guidance, George soon came to the flat rock wall. After seeing the rock wall, Chris swam to the edge of the flat rock wall, looked at it carefully for a while and said, "Boss, this rock wall is used for concealment as you analyzed. I just looked at the edge of this rock wall. Obviously, if this is really the entrance to the base, then when the gate is opened, this rock wall will be driven into the rock layer next to it. There are some inconspicuous gaps here."

George was wearing a sealed helmet, so he could make a wireless call. Yang Jing and the others were wearing waterproof headphones. Although they couldn't speak, they could hear what George said.

Yang Jing made a few gestures to George, and George nodded and began to place the C4 at the bottom of the flat rock wall.

This time the blasting would not blow up the entire rock wall. Yang Jing only asked George to make a hole in the lower part of the rock wall. He did not want to blow up the steel door inside, but only wanted to blow up a gap in the rock wall outside that was used as a cover.

George was very efficient. He spent more than ten minutes placing several pieces of C4 at that location, plugging in several electric detonators, and then connecting the wires between the radio detonator and the electric detonators. He then placed the detonator in an automatically inflating airbag and let the airbag bring the detonator to sea level.

It is absolutely impossible for Yang Jing and his team to detonate the explosion underwater. Not to mention other dangers, the huge crater beneath them alone makes them dare not act rashly.

The electric detonator and the radio detonator are connected by a waterproof wire more than 50 meters long, and then the detonator will rise to the sea level. After Yang Jing and his team return to the surface, they will leave the range of the crater and detonate the detonator from a distance using radio control.
