Far away in the United States, in a diving suit research and development company, the general manager held an order that had just been sent over, and he was quite high-spirited, and he gave a speech to his subordinates in a passionate language.

"This is an order just sent by a Chinese customer, involving more than 50 million US dollars. They are not very demanding, they only need our wetsuits to go beyond the limit and reach deeper seas. Ladies and gentlemen, this is a great opportunity for our company, do you have the confidence to overcome the difficulties of seabed pressure? The green ticket is beckoning to us, what are we waiting for?" the general manager began.

Foreigners speak differently, and in China, such formal occasions, they generally do not use this kind of intonation, as well as relaxed language.

People who work in large domestic companies know that leaders are generally very serious when they hold meetings, and they just need to create pressure on the people below them to form a so-called official authority, so as to deter their subordinates and make them do things obediently.

$50 million is not an astronomical amount, at least in a place like the United States, in a large company like this. Even for medium-sized companies, if the business is good, the transaction volume can reach this amount in a quarter.

What John really values is the prospect of wetsuits, which become more and more relied upon as the depths of the ocean develop. This product will only become more and more marketable. Of course, if you don't want to be eliminated by the market, you have to constantly update your technology and keep breaking through the limits.

This order is just taken out to stimulate employees. Next, he will develop a reward scheme to reward all employees who participate in the development of better wetsuits.

There is an old Chinese saying that is very good: under the heavy reward, there must be a brave man!

Living in this country, people are more materialistic and have a stronger need for money. Therefore, when the reward plan was distributed, everyone looked at it and became excited.

"Remember. We want to create a world-class wetsuit. Whoever of you has contributed wisdom will definitely not be less bonus. John said to the staff.

Although the diving suit is not as expensive as the spacesuit, it is tens of millions at every turn, but it is better because the sales of this product are more. John believes that there is definitely a premise than a spacesuit.

At least, it's a big trend in the short term. When space development reaches its climax, perhaps the landscape will change.

Aviation clothing can protect against the hazards of environmental factors such as vacuum, high and low temperature, solar radiation and micrometeors in space. Well, the technology it requires is too complex. Therefore, it is difficult to avoid high prices.

The general wetsuit is used to prevent the body temperature from being lost too quickly during diving. It causes hypothermia while also protecting the diver from reefs or harmful animals and plants. There's no technology to speak of, so it's cheap. At present, the market for deep-sea diving suits developed is getting bigger and bigger.

The biggest consideration in the development of this diving suit is the impact of the pressure on the human body on the seabed, and when designing, it is necessary to work hard to solve this problem and eliminate the adverse effects of pressure.

Secondly, there is the temperature factor. As everyone knows. The deeper the seabed, the higher the pressure, the lower the temperature. However, there is a limit to how low it is. It can't be below freezing, after all, the sea is going to freeze at that time.

In the Provincial Museum of Guangdong Province, many people gathered. Among them are experts in antiquities, as well as archaeologists, as well as members of the museum.

"The discovery of this giant ship. It is the largest ship in the history of Chinese salvage. It's a pity that the water is too deep and too far away, so I can only put it over there first. An old-timer spoke.

The tone was full of regret. When he got the news, he rushed over. Everyone was deeply shocked when they saw the content on the video.

Everyone has heard of Zheng He's treasure ship, and there are many records in the history books. But if you don't see the real thing, even your own people will be suspicious, at that time, can you build such a huge ship?

This video confirms the pinnacle of ancient Chinese shipbuilding technology, with huge hulls and complex processes, many times ahead of the world at that time.

"If this technique had not been lost, why would the Qing Dynasty have been bullied by the great powers and could not hold its head up?" someone said.

"That's not easy to say, after all, in the late sun, the West's technology is changing with each passing day, and it has completely surpassed China. We must acknowledge this fact. The old man shook his head.

At this time, they had already discussed with the scientists of the Tangjiacun Biological Research Center to borrow their submersible for the time being.

The submersible filmed the entire salvage process and teleported it directly to this side. In fact, it is equivalent to this is the command center, and those who can't be touched, they can reach Wei Hang's ears in time.

"This young man is good. He seniors praised.

As far as he knows, there are very few divers who can dive that deep, and it is this that has caused the current situation of deep-sea salvage has been stagnant.

"He Lao is not wrong, this kid has made a lot of contributions to the country, a month or two ago, our country discovered a new island rich in products, which he made. In addition, before that, he had salvaged shipwrecks on the high seas and obtained a large number of cultural relics, some of which were auctioned and some of which were donated to major museums. ”

At this time, the owner of the Deng Pavilion was also stingy in promoting Wei Hang and strengthening his connections.

"Well, the country needs a lad like him. He Lao said with a smile.

Inside the hall, a group of people gathered around a large screen to observe.

"Let him go to the room on the left, which is the head room. "That is, the command center of the whole ship, where you should be able to find some useful information.

After receiving the command, Wei Hang took the shooting instrument and walked into the room where the sludge was still flowing. Under the immersion of seawater, the wood of the hull was not broken, and when I rubbed it by hand, it actually glowed.

The people who gathered around the screen to observe were all sighing when they saw this scene.

"It's a metasequoia wood, and it's also the heart of the tree, so it's extremely precious. An expert immediately judged.

Metasequoia is a large deciduous tree with a straight trunk and branches sticking out obliquely to the side, making the whole tree look like a pagoda. Its branches and leaves are sparse, the tree shape is beautiful, both simple and elegant, but also solemn and dignified, the bark is russet, the leaves are slender, very flat, drooping downward, and fall off after autumn.

The economic value of this tree is very high, its heartwood is purple-red, the material is fine and soft, it is a good material for shipbuilding, construction, bridges, agricultural tools and furniture, and it is also a raw material for papermaking with excellent quality.

Perhaps, many people have seen this kind of tree, and it is not unusual.

But few people may know that Metasequoia is the giant panda of the plant kingdom and is known as a living fossil. It is an ancient relict plant that only grows in China, so people call it "China's national treasure".

The expert still remembers that after the discovery of the ancient metasequoia tree in China and its announcement, it attracted the general attention of the botanical circles in the United States, and many world-famous botanists and paleontologists traveled far and wide to observe and inspect the ancient metasequoia tree.

"Metasequoia is a good material for shipbuilding. The person next to him immediately pointed out.

There are many types of wood used in ancient Chinese shipbuilding, which are generally made from local materials, and the best of the best. And according to the different characteristics and properties of wood, it is used in different parts of the ship.

Generally speaking, the material of cedar is relatively soft, and it is not suitable for making things that have to withstand great resistance.

However, the fir core is different, it is hard, the material is light, and it is resistant to blisters. Therefore, it is a good material for making boats. Another reason is that there are many fir trees in China, and they are easy to grow, and some of them have been very tall for decades.

"That deck just now looks like a sassafras tree. "Just now, I didn't actually see it clearly, that guy from Weihang walked around, in fact, he was just looking around, which made these people who wanted to study a little crazy.

There is a saying in ancient shipbuilding, called: a thousand years of needles pine a column, ten years of sassafras trees are good for boats!

As for the bottom where the ship comes into contact with the seawater, it should be teak.

Teak is one of the most prized timber species in the world. The material is yellow-brown or dark brown, the wood is fine, the hardness is high, and the texture is beautiful. In the case of sun and rain, dry and wet changes, it is not warped or cracked, it is water-resistant, fire-resistant, can resist termites and sea insects in different sea areas, and is extremely resistant to corrosion.

"Tell the lad to stop and look to the right, there's a cabinet there, and see if you can open it." "Although He Lao is old, his eyes are very powerful. Wei Hang just shook the camera for a while, and he actually saw it.

After receiving the order, Wei Hang walked towards the cabinet. After walking over, wipe the cabinet with your hands as well.

As soon as the mud on the top was wiped away, a touch of gold appeared in Wei Hang's eyes. And the onlookers also shrank their pupils, revealing shocked looks.

"It can't all be made of gold, right? Third brother, you quickly wipe the whole cabinet. Chen Jianliang yelled on the boat.

Weihang has a black line, do I just wipe it off when I come down?

The mud covering it was roughly wiped away, and the glittering golden cabinet appeared in front of everyone, and everyone on board swallowed. How much is this cabinet worth alone?

It can also be seen how much gold and silver treasures Zheng He earned from overseas when he went to the West. On a ship, built so luxuriously, it must have been a profit.

Wei Hang took a closer look and found that there was a lock on the cabinet, and locked the cabinet firmly. He spread his hands and said that he was helpless.

"Third child, hurry up and get the rope in, tie the cabinet, and I'll let the salvage boat pull it up. Chen Jianliang was a little impatient.

And on the side of the museum, the owner of the Deng Pavilion and others are also curious, inside the cabinet, there must be very valuable things locked. Perhaps, there is some information hidden in it that is very helpful for their archaeology.

"Be careful not to damage the rest of the hull. "They only have one request. (To be continued......)
