In many legends today, this sea area is home to the largest pirate treasure that has yet to be discovered.

Experts speculate that many of the treasures either sank to the bottom of the sea with pirate ships sunk by the navy, or were lost due to infighting among pirates.

According to statistics, 45 out of every 100 gold and silver ships shipped from the American colonies to Spain were sunk to the bottom by pirates and storms.

Since 1498, when Columbus crossed the Atlantic for the third time, at least thousands of ships of all kinds laden with gold, silver and jewels have been sunk by storms and pirates.

The Caribbean is a place of pirate treasure and shipwreck legends laden with gold and silver riches.

Chen Rui locked on the target of this underwater treasure hunt in the Caribbean Sea.

The next thing he needs to do is narrow down the treasure hunt target.

You must know that the area of the Caribbean Sea is 2,754,000 square kilometers, equivalent to more than one-third of China's land area, and the average water depth is 2,500 meters.

Therefore, Chen Rui wants to narrow down the scope of treasure hunting to a certain sea area of more than ten square kilometers.

It was the thriving shipping routes that the Spanish ships used to transport gold and silver treasures at that time, or the places frequented by pirates, or the sites of shipwrecks recorded in historical documents.

To this end, Chen Rui has made a lot of careful preparations.

Within a month, I searched for a lot of literature on the Internet, read a lot of books and materials about navigation, treasures, pirates, shipwrecks in the Spanish colonial era in the local library, and finally asked the coastal fishermen for some information.

Eventually, Chen Rui narrowed his sights to a sea area southeast of Belmudez, Cuba.

In this area, a large number of Spanish merchant ships, gold ships and pirate ships have been sunk by storms or raiding pirates, forming a world-famous undersea 'treasure cemetery'.

Half a month later, a lot of careful preparations were made.

Chen Rui came to Belmudez, Cuba, rented a yacht and drove to the sea.

Based on the clues of the previous reading of the literature, it is inferred that the most likely place for a shipwreck has been moored.

During the Spanish colonial era, the area covered an area of several tens of square kilometers, and pirates sank several merchant ships carrying gold, silver, spices, and jewels back to Spain.

This is clearly mentioned in both the materials searched on the Internet and the information found in the library.

After mooring the yacht, Chen Rui jumped into the water.

Chen Rui's strange behavior is not surprising, because in this sea area, there are often such diving enthusiasts.

After jumping into the sea, the water splits and the sea water separates automatically.

Soon, Chen Rui dived to the bottom of the sea at a depth of more than 100 meters.

The bottom of the sea is a little shady, and the water is a little cold. However, the eye can still see the surroundings clearly.

You can see a beach, a reef and a swimming fish, sea creatures.

Chen Rui carried a metal detector with him.

Chen Rui began to search the bottom of the sea.

In the process of searching, Chen Rui did not forget to send the underwater creatures that can be seen on the bottom of the sea to the pregnant Haizhu Ocean to supplement the biological species of the pregnant Haizhu Ocean.

The most common sea creatures are tuna, barracuda, lionfish, grouper, etc.

After searching for most of the day, the carpet searched the seabed several hundred meters nearby, and the ghost of the sunken ship was not seen.

Just when Chen Rui wanted to go up and rest for a while, he suddenly found a fish with a body length of more than 1.5 meters swimming towards him.

The body of the fish is long fusiform, the body is thick, the head is large, the mouth is wide, the teeth are sharp, the body is covered with large and thin oval round scales, and the scales are exposed with many small ridges or wart processes, and the body surface is rough.

Chen Rui almost immediately had a name in his mind, 'speartail fish'.

It is very recognizable because its tail fin shape resembles a spear-like trefoil, hence the name 'speartail fish'. ’

This is a big guy, the length can reach 2 meters, and the weight can reach 90 pounds.

It is also a ferocious predator, with squid, squid, and other deep-sea fish and even tiny sharks on its diet.

What makes it famous is that it is the oldest 'living fossil' in the ocean, the only living totalfin fish, and all other taxa of totalfin fish are extinct on the planet.

This fish, which lived from the end of the Permian to the early Creta, was once thought to have gone extinct 70 million years ago.

However, in December 1938, the first speartail fish was caught in the deep sea off the southeast coast of Africa, near the island of East London, and the mystery of catching speartail fish attracted the attention of all walks of life around the world, sparking a great debate among biologists about the traditional theory of biological evolution.

The second speartail caught in 1954, in the Comoros Islands of Africa.

In 1982, the government of the Comoros donated a precious specimen of speartail fish to China, which is now preserved in the Chinese Museum of Ancient Zoology.

In 1998, a speartail was caught off the coast of Indonesia.

Almost every speartail catch attracts worldwide attention.

Chen Rui stood still, and when the speartail fish approached, Chen Rui suddenly launched and collected the big fish into the pregnant sea pearl.

When the speartail fish entered the sea of the pregnant sea pearl, they immediately became more energetic, and seemed to be extremely satisfied with the environment, and immediately began to chase and prey on the sea creatures that had just been released into it.

Catching a cherished abnormal speartail fish, Chen Rui said secretly, "Today is finally not in vain. ”

He was ready to get on the ship, leaving a mark, intending to look here for a long time.

The previously demarcated search scope is not small, and it will take at least half a year to search for all of them.

Seabed.

Chen Rui is holding a metal detector and scanning the seabed.

I have been searching for the bottom of the sea for more than half a month, and I haven't even seen the shadow of the sunken ship, and I have gained zero.

Fortunately, Chen Rui caught a speartail fish again. This speartail fish is female, and a male speartail fish caught before, one male and one female, just matched into a pair, which is a very unexpected surprise.

According to the usual practice, Chen Rui collected all the discovered seabed creatures into the pregnant sea pearl, supplementing the ecosystem in the ocean of the pregnant sea pearl space, so that the marine system in the pregnant sea pearl space tends to circulate steadily.

Coral reefs, planktonic seaweeds, benthic algae and marine seed plants, various marine organisms, marine bacteria and fungi, as well as inorganic substances involved in the material cycle, such as carbon, nitrogen, sulfur, phosphorus, carbon dioxide, and water, constitute the marine ecosystem of the entire pregnancy pearl space.
