"The submersible and submarine diving methods are the same, both injecting seawater into the air compartment. However, the floating method is different. When the submarine floats, compressed air will be used to force the seawater in the air compartment out; while the deep-sea submersible has deep diving and high environmental pressure, and the compressed air is not enough to force the seawater in the air compartment. It will use the method of discarding ballast iron to achieve floating."

"It is worth noting that deep-sea submersibles generally control ballast iron through electromagnets, so if the deep-sea submersible loses power and the electromagnet fails, the ballast iron will automatically leave the submersible under the action of gravity, causing the submersible to float."

After pausing, David continued: "The pressure of 5,000 meters underwater is equivalent to 500 atmospheres, which is equivalent to a weight of 5,000 tons over an area of ​​1 square meter. Boss, imagine how much pressure this submersible needs to bear?"

Fang Yuanshan knew this, but before, he had just scanned the book and had no intuitive understanding. At this time, when he heard the explanation of "Tank", his face changed. Under such a great pressure, it was a deep test for the shell of the submersible.

"What about its material? Under such a large pressure, ordinary materials cannot bear it!"

"Well, currently, new composite materials are mainly used. As long as they are within their dive regulations, there is no need to worry about compression resistance."

Today, "Uncle Sam" from New Zealand asked the manufacturer to deliver the deep-sea submersible. Looking at the large round ball in the container, Fang Yuanshan thought of a question and asked: "What about the power of this thing? How to sneak underwater and what is the range?"

The engineer who came with the car also stood beside him. When he heard him ask such a question, he couldn't help but turn his eyes to David for help. David was also a little helpless. The boss thought that he had spent millions of dollars to buy a submersible, and didn't ask how to use it.

Seeing that the boss was still waiting for his answer, he shrugged and said, "Boss, I'm sorry to tell you that the main technical difference between a deep-sea submersible and a submarine is that the deep-sea submersible is not completely autonomous, and must rely on the mother ship to replenish energy and air."

"What's the meaning?"

"Uh... Simply put, you also need to buy a supporting large ship. Then after each dive, the submersible will be recycled onto the mother ship instead of driving in the sea. You should see that this deep-sea submersible is small in size and has a short range. It does not have the living facilities of a crew like a submarine, so naturally..."

David understood what he meant very well. Just such a big thing, you have to consider safety, and you have to be equipped with electronic equipment and basin items, and also have a certain battery life. What else do you want?

"I...Fuck, I spent millions of dollars to buy a piece of iron to come back?"

The engineer next to him was a little embarrassed and blushed, "You can't say that either, at least the things inside it are the most advanced in the world."

"Forget it, teach me how to use it."

Fang Yuanshan, who was depressed for a while, finally followed the engineer to the container. In addition to a whole shell, there were some scattered external instruments and equipment. After the engineer opened the hatch and entered it, he explained the uses of each button and how to operate it. Finally, he said: "Mr. Fang, I suggest you buy a mother ship produced by our company, which will have a great effect on the later use of the submersible."

"How much?"

"Uh...not expensive, about 4.5 million US dollars"

"No need, I'll put this submersible back to play at home."

“…”

The engineer looked like he ate a fly and finally said helplessly: "Okay, if Mr. Fang has any questions, you can call me anytime, and I will stay in Rio for a week."

"Okay, you go, I'll study it myself."

After the engineer left, Fang Yuanshan's face did not show any disappointment. In fact, it doesn't matter whether this submersible has power or not. He might have needed to sneak in the deep sea before. Now that he has space to move, just wrap the submersible and "run" forward...

After seeing that there was nothing wrong, Frank and others began to prepare for things to go to Colombia. Jonson Lance and the American girl were all driven away by him, leaving him and a few transport masters behind.

Without the mother ship, the external connection equipment of the submersible was not needed for him. The group drove the container toward Villa No. 1 in Copacabana, where a hoisting machine was already waiting.

When the container came, several workers connected the snaps and then went into the water with a "boom". The owners of the yachts and cruise ships basically knew Fang Yuanshan. When he saw him getting a lump of iron, they all surrounded him and asked.

"Hey Fang, what are you going to do?"

"Mr. Fang, are you a new yacht?"

“…”

Many of the people who surrounded him were company bosses, chairmans and the like in the commercial area. In addition to being curious, these people also made more of their efforts to make good friends with him. After all, Fang Yuanshan is worth tens of billions and is "kind" and has no airs. If something happens in the future, as long as it is not too outrageous, according to his personality, he will probably not be able to save him.

Although it was already past four o'clock in the afternoon, the sun in the sky was still hanging high in the sky. When tourists in the distance saw such a big movement here, they all wanted to lean towards it. Unfortunately, due to the large number of people on the beach recently, the yacht marina has been subject to control, and most people cannot enter, so they can only watch from a distance.

Fang Yuanshan, who was standing on the dock, had a smile on his face and said with a smug expression: "Hey, it's boring to always play cruises. Recently, I'm thinking about going to the bottom of the sea to play. Isn't I buying a deep-sea submersible? How about it? Isn't it okay?"

There are no less than 100 cruise ships of various types on the yacht pier here, and there are more in Rio State. But so far, Fang Yuanshan, who plays underwater submarines, is probably the only one. This courage to be the first immediately made the boss and chairman be flatter him, making him laugh.

The water was still debugging. Among the tourists watching from a distance, a beautiful figure came over, with a slim figure, fair skin, and a high-pinned bun that looked like a noble lady.

Seeing a large group of people around here, the "Niu Miss" took off the wide-edged sunglasses on the bridge of her nose, and a standard beauty face was exposed. It was the uninvited "white and rich beauty".

Bai Rui is naturally familiar with cruise ships and yachts. She has seen all kinds of yachts in China, and there is also a super luxurious cruise ship at home. After looking at them, she lacks interest. As soon as she was about to wear sunglasses and leave, a familiar figure came into her eyes in the distance.

"Hey, isn't this guy? Why did you come here?"

If you want to talk about the reason why Bai Rui came to Brazil, in addition to Fang Yuanshan showing her a superb "magic" on the plane, there is another reason that she has never been to Brazil before, so she just came to play for a while. And to be honest, Fang Yuanshan gave her a feeling that she had a "game of the whole picture".

Seeing Bai Rui, who was "acquaintance", looked at her eyes, found a white man who looked like a local, walked over and asked in English with a smile: "Hello hello"

After being called up by a pretty woman, the young white man smiled and returned with a smile: "Hi beauty, is there anything wrong?"

"Do you know what the Chinese man in white T-shirt on the dock does?"

The man subconsciously glanced at the direction she was signaling, and turned around and said disrespectfully: "Oh, you said Fang, he is the owner of Villa No. 8."

Bai Rui blinked and asked, "What else?"

The white man who thought there was something "good" looked at her, then looked at Fang Yuanshan in the distance, and understood it immediately. Both of them were Chinese, so this girl might have fallen in love with that Fang. He spread his hands and said, "Sorry, I don't know anything else."

Before Bai Rui could reply, the white man followed and said, "Miss, how about I treat you to a drink?"
