Tang Hai's whole person swims in the water, his strength is very strong, and he can swim far away with a single movement.

He estimated his true speed, which should be about the same as that of an adult dolphin without the help of the home court.

He came here to find out if there were any shipwrecks from hundreds of years ago.

The United States is a country of immigrants, originally a 'prison' for the exile of the most vicious people, and later it became a place where the people of the lower classes of European countries liked to immigrate.

Until the American Monopoly War, the United States was seen as a penal colony for the wicked.

Actually, that's true, and it continues to be so for more than a hundred years.

For example, Lincoln, the great leader of the 'emancipation of black slaves', who would have thought that he would promulgate the Homestead Act and support the "killing of all Indians", and the remaining 4 million of the 80 million Indians in the Americas were killed, and the remaining 200,000 were killed by 10 million Indians in the United States under his orders. In those days, human skin was also a leather material.

The reason why Tang Hai explored this place was because he thought that so many people who were exiled at the beginning were extremely vicious people, and such people often had some private property, plus they drove boats around, and there were also those who secretly escaped during the Civil War...... There's a bit of a shipwreck here, and it makes sense......

According to the study, there are about 3 million shipwrecks in the ocean, and only a very small number have been salvaged!

Tang Hai was skeptical of this number, but he firmly believed that there were a lot of treasures in the ocean.

Shipwrecks, ruins, minerals, high-quality large fish, whatever is found, is a great treasure! There are even family-based expedition companies in the United States, and there are quite a few of them, and they look for treasures in the sea all day long when they have nothing to do!

As soon as he came out of the fishing grounds, he couldn't beat the big fish Tang Hai, he couldn't recognize the minerals, and the ruins were estimated to be tens of thousands of years ago, and they must have been buried, and it was not easy to find.

Thinking about it, apart from looking for a ship, Tang Hai couldn't find anything else.

It's just that most shipwrecks are in the deep sea area, and for every 10 meters of ocean depth, the water pressure will increase by one atmosphere, in other words, the depth of 13,000 meters in the deep sea is a full 1,300 atmospheres! Even if the poplar willow wood falls to that position, it will be compressed by the sea pressure by half of its volume, and Tang Hai will definitely not be able to go down now!

The closer the shipwreck is to the coast, the easier it is to be found, especially some very important ships, whose routes are known and where they sank are also found......

Of course, there are exceptions!

In an area as developed as San Francisco and as modern as the Golden Gate Bridge, a sunken treasure ship was found near the Golden Gate Bridge last year!

In the antique market, everything is sold by the piece, which is basically a modern handicraft.

In shipwrecks, artifacts are often found by the ton, and they must all be antiques.

It's not hard to see why Tang Hai is here!

……

With Tang Hai's physical fitness, there are also limits to going to the sea without anti-pressure suits, for example, now that he has gone to a depth of 60 meters under the sea, Tang Hai's lungs are full of seawater, and his lungs can now be used as gills, which is also a little uncomfortable, not to mention that his ears are starting to hurt.

In front of him is a ** seagrass, the bottom of the sea is dense with fine sand, and there are many corals, antler-shaped, cactus-like trees, mushroom-shaped......

Separate the seaweed in front of you, and there is a big rock in front of you!

"Damn it!" Tang Hai's legs were forced, and the whole person rose more than ten meters high!

It's not a way to go down to explore, how long will it take to explore such a large sea area?

There is no way to come up, although his eyesight is estimated to be many times higher than that of dolphins, but the shipwreck hundreds of years ago must have been covered with seagrass or sediment, and even if there is, Tang Hai can't see it from too far away.

"Fatty, do you know what shipwrecks are there?" Tang Hai patted the dolphin next to him, this dolphin was obviously overweight, and he heard the boss say that the owner of the raft used to be a good fisherman, Tang Hai knew the reason why this guy was overweight when he thought about it.

It's a pity that the big dolphin didn't understand Tang Hai's words, thinking that he was going to play with it, and knocked Tang Hai over again......

"I want to be calm, I must have the right skills to use at this time!" Tang Hai floated in the sea, clenching his fists to cheer himself up.

A school of sea fish, more than a foot long, numbering about hundreds, crossed over the top of Tang Hai's head!

Tang Hai raised his head and saw the blue waves on the water, as well as this group of fish dancing, and the shock in his heart.

He once saw a picture where a photographer was lucky enough to come across a school of millions of fish and photographed it.

It's just that the things on the picture are different from seeing them with your own eyes!

"Wait, and then think, I must have the skills to find a shipwreck! I'll look for matsutake mushrooms, I'll look for mushrooms! ”

But it's not about finding a boat!

"I am a senior geographer who knows the topography by looking at the mountains and knows the water waves......

It's still useless to think about it.

"I'm still looking for winter bamboo shoots!"

Winter bamboo shoots grow in the soil, and after being unearthed, they will be hard when they are unearthed, and they will not taste good.

Tang Hai can look at the withering glory of the bamboo, and he can know if there are new bamboo shoots coming out, many middle-aged bamboo shoots diggers don't have this ability!

It doesn't seem to work......

"I can also fish! Forget it, fishing is not too difficult a skill to learn, Rose has learned it all......"

"Wait, it works! As a good fisherman, I actually forgot about wreck sea fishing! Tang Hai suddenly became excited!

The reason for the formation of the strongest fishing ground is the convergence of cold and hot currents, the heat flow automatically rises, and the cold current automatically sinks.

However, what many people don't know is that if a shipwreck is a little bulky and can block the current, it will also cause an upward or downward current, which can also impact the minerals!

With minerals, there will be aquatic weeds and small fish and shrimp, and then there will be big fish......

And there will be many cabins in the wreck, and when a fierce undercurrent or storm comes, many small fish like to hide behind!

Tang Hai used to go fishing near the open wrecks provided by some anglers, and the harvest was obviously several times more than other places in the same waters!

If there is really a shipwreck, even if it is covered with a layer of sediment and aquatic plants, Tang Hai can also be seen from the density of biological life!

This is the synthetic technique after the wreck fishing method and a pair of heavenly eyes: treasure hunting!

Tang Hai swam upward, turned around the neighborhood, and finally found a place where the white life light was suspiciously dense, these lights were not seagrass, but small creatures!

He landed vertically, and the dense seaweed swarms were stacked on top of each other, and it was really terrifying......

Tang Hai fell to a 'ground', and as soon as he stepped on it, even if it was covered with a layer of sand, he knew that it was a plank!

"Sure enough!" Tang Hai was excited, increased hormone secretion, stepped on it violently, and tens of thousands of pounds of huge force couldn't remove much even from seawater, and directly cut out a small hole!

The treasure is in front of him, where would Tang Hai think too much, and he plunged into it directly!

The seagrass below was so dense that it was impossible to see what was going on at the bottom, and the dolphins didn't dare to go down, so they just watched Tang Hai 'disappear'.

Suddenly, it sensed extreme danger and whined a sonic alarm!

It is clear that Tang Hai does not have the ability to receive such alerts.
