After the 'water escape' became small, Chen Rui felt that he was like a fish in the sea, swimming was like his natural instinct, and he was at ease in the water and acted as he wished. As long as he gently stroked his arm, his body was like an arrow from a bow, and the person had appeared dozens of meters away.

Swimming back to the shore and standing on the reef, Chen Rui looked at the boundless sea in front of him, and suddenly a thought came to Chen Rui's heart.

I remember watching a documentary on the Internet about the treasure of a shipwreck under the sea.

According to UNESCO, there are about 3 million undiscovered shipwrecks in the world's oceans, although most of them are of limited value.

However, experts have estimated that there are more than 3,000 shipwrecks carrying gold and silver treasures on the seabed, and there are many more shipwrecks that are not loaded with gold and silver treasures, but their goods are extremely valuable today, including ivory and porcelain.

The wreck was kept in the absence of air in the ocean, and part of the cargo lying in the deep water was very well preserved.

For example, in China's coastal waters and the South China Sea, the Song, Yuan, and Ming dynasties, China's maritime trade was very prosperous, when the main items of Sino-Western trade were silk, tea and porcelain, etc., it is estimated that there are 2,000 to 3,000 shipwrecks in China's coastal waters and the South China Sea, most of these shipwrecks are ancient Chinese fine porcelain, experts say that these shipwrecks constitute a 'submarine porcelain capital'.

In the Persian Gulf, from the 8th century AD to the Age of Discovery, a period when the flourishing maritime trade brought endless wealth to the Arabs, it also left countless shipwrecks in the Persian Gulf.

Because the Arabs were good at reselling Western luxury goods to the East, and then selling Eastern spices and porcelain to the West, there were many treasures on the shipwreck, including porcelain from the East, gold and silver art, ivory, etc. from the West.

In addition to the South China Sea and the Persian Gulf, there are also the Mediterranean, the Atlantic coast of the Iberian Peninsula, the British Sea, the Baltic Sea, and the Caribbean, where a large number of shipwrecks have sunk on the seabed.

These shipwrecks include merchant ships, treasure ships and pirate ships.

The treasures in the shipwreck include gold, silver, jewelry, gold and silver art, ivory, porcelain, etc.

Only a small fraction of these mysterious treasures have been discovered by explorers, and most of them remain in a corner of the ocean floor, attracting treasure hunters, archaeologists and more.

Most of the time, shipwreck treasures look like legends until explorers salvage them from the ocean floor and turn them into real, piles of gold coins.

The world is not only looking for treasure by pirates and ocean exploration companies, but also by individuals, families and even entire families.

For example, the 'treasure hunter' Mel. On July 20, 1985, Fisher's family went into the water to search, and on July 20, 1985, they found the "Lady Atoka", the wreck of the largest treasure under the sea, with 40 tons of treasure, including 8 tons of gold and 500 kilograms of precious stones, worth 400 million US dollars.

Of course, Mel. The Fisher-Price family is a very lucky family, and most of the treasure hunters or ocean exploration companies have found nothing.

The underwater treasure hunt was supposed to be an adventure full of hormones, mysterious maps, and intrigue.

It is very difficult to find the location of a shipwreck, and it is a huge undertaking from research to exploration.

For example, when Odyssey was looking for the Republic, it first collected documentary information, then carefully analyzed the shipwreck of the Republic, and used computers to simulate the line and speed of the ship in that year. Eventually, the wreck was locked within 1,500 miles.

1,500 miles -- just combing through such a large area of ocean floor with sonar is a tremendous amount of work.

For Chen Rui, it is relatively simple to find the location of the wreck on the seabed.

Moreover, from research, search, exploration to salvage, the most difficult step and the most expensive step is salvage.

The simplest example, Jasonii, a deep-sea work machine, costs $2.5 million, and now the price of a more advanced deep-sea work machine has tripled.

There are also large submarine excavators, which are more expensive.

After all, the machine is not human, and during the salvage process, some valuable, fragile items, such as porcelain, and artworks can be accidentally damaged.

Another point is that no matter what kind of texture the utensils are, soaking them in seawater for a long time will generally have a negative impact on their protection. In addition to the gold products are more corrosion-resistant, generally silver, copper, iron, tin and other materials will be affected by the strict, many metal cultural relics just out of the water when the section is as bright as new, but after contact with the air is quickly oxidized, and eventually become powdery.

In addition, once the porcelain itself is separated from the environment surrounded by seawater, and after being exposed to the air for a long time and dried, the salt that has been infiltrated into the body of the porcelain will continue to precipitate from it, causing the glaze layer to crack and cause peeling from the carcass.

However, Chen Rui has a pregnant sea pearl, these are not a problem, and he directly collects the treasure into the pregnant sea pearl for preservation.

The water division + water escape gave Chen Rui great convenience in searching for the wreck.

Pregnant Haizhu brought great convenience to Chen Rui to salvage and preserve treasures.

Come to think of it! Chen Rui's idea of treasure hunting under the sea became even more urgent.

The next day, Chen Rui stayed in the rented hotel and did not go out.

The undersea treasure hunt is a three-step process.

Research, search, exploration, salvage.

Chen Rui's undersea treasure hunt starts with research.

Search for information about shipwrecks, stories from fishermen, and logbooks.

In fact, there is no need to deliberately look for it, now that Zixun is so developed, as long as you search and enter the undersea treasure + Caribbean on the computer, or the undersea shipwreck + South China Sea, you can search for countless pieces of information about this.

But that's all there is to it, and more detailed information is not available with Chen Rui's current ability.

After searching on the Internet, Chen Rui quickly locked on the Caribbean.

When it comes to the legend of the treasures of the sea, the Caribbean Sea will definitely come to mind first.

During the colonial era, the gold plundered by Spain and Portugal from Central and South America had to be shipped back to Europe through the Baltic Sea, so this area was also one of the busiest seas at that time. In addition to merchant ships and official ships, there are also a large number of treasure looting pirate ships. This makes the Caribbean region the most frequented area for man-made shipwrecks.
