A diving depth of 100 meters is already the limit for ordinary people.

It can be said that the vast majority of diving enthusiasts have no way to dive to this depth without oxygen.

And Su Yi is now an anaerobic dive, without the help of an oxygen cylinder at all, and just relied on himself to dive to this depth in one breath.

It is said that anyone who has come into contact with an amateur of oxygen-free diving will become addicted to this sport and will never want to leave the sea for the rest of their lives.

Even though this sport is very dangerous and very difficult, it is not something that ordinary people can easily challenge, but every year more and more enthusiasts still participate in it, and there is only one goal in mind, that is, to surpass it.

Going ashore, diving, and repeating again and again, is to complete the challenge again and again, and the charm of this touches the hearts of diving enthusiasts.

Su Yi is in this situation now, he feels that diving is getting more and more interesting, and he wants to know where his limit is.

Although he did not have any professional training in related fields, let alone any relevant equipment, he was just an ordinary swimsuit, and he went into the water like this, but his speed was extremely fast, and the speed of diving into the bottom of the sea was much faster than ordinary people.

The depth of one hundred meters was quickly exceeded, and it immediately headed for the one hundred and fifty meter mark.

Now the diving depth where Su Yi is located has already exceeded the depth of 150 meters, which is equivalent to breaking the record of anaerobic freehand diving.

It's just that he hasn't reached his limit yet, and he feels that he can still try a deeper speed, so his speed doesn't slow down, and he still swims towards the bottom of the sea.

When Su Yi dived to a depth of about two hundred meters, he stopped, not that he had reached the limit, but that he had reached the bottom of the sea, and there was no way to continue unless he continued to swim farther away.

Of course, he didn't really know the specific depth, only a rough estimate, but he could be sure that the depth was more than two hundred meters.

Without relying on diving to a depth of 200 meters, this feat is very amazing, and at the same time, in the eyes of many people, it is also incredible, it is very difficult to accomplish, and it has already exceeded the world record too much.

However, Su Yi knew that he had not yet reached his limit, and he could continue to challenge deeper.

It's just that he also knows that in this regard, it is difficult for humans to compare with some animals.

For example, some marine animals that are good at diving, which are difficult for humans to catch up with even their best efforts, such as sperm whales.

The sperm whale is top-heavy, especially suitable for diving, in order to eat the king squid hidden in the deep sea, the sperm whale can dive to a depth of 2200 meters, and can dive breath-holding for up to 90 minutes, so it is the diving champion among mammals

The champion among the birds was the emperor penguin, which recorded a dive that lasted 22 minutes and reached a depth of 550 meters.

At depths above 366 meters, animals are subjected to 40 times the atmospheric pressure they would be exposed to on the water, and the oxygen supply to the brain and other organs is very limited, because the air in the lungs is squeezed to one-fortieth of the normal volume, and this tremendous pressure causes the nitrogen in the blood vessels to break down, which is a lethal environment.

As for the animals that dive the longest breath-holding in the water, it is the sea turtle, because the turtle does not have gills and also needs to rely on the lungs to breathe, so the turtle will swim to the surface of the water to breathe every once in a while

But turtles can dive underwater for several days and nights after taking a breath, but if frightened, they can drown.

Therefore, it is very difficult to dive for long periods of time with your breath held, especially after reaching a certain level, and there are many animals that have an innate advantage over humans in this regard.

However, these congenital disadvantages can be remedied by the day after tomorrow.

Just like Su Yi now, his body has also broken through the limit and completed incredible feats, and the results are still far from the records of some animals, but he believes that as long as he persists, sooner or later, he can surpass these animals.

After diving to the bottom of the sea, Su Yi was not satisfied, he also wanted to dive deeper.

It's just that this is already the deepest, and if you want to dive deeper, you can only go farther into the deep sea.

So, Su Yi continued to swim forward, he wanted to go deeper into the deep sea, he wanted to continue to test his limit, and once again exceeded the depth of two hundred meters.

It's just that he didn't swim far, but he suddenly stopped.

Because Su Yi suddenly saw a pile of black stones in front of him, there seemed to be something stuck, which seemed to be a big fish that was still struggling.

Out of curiosity, he did not continue to swim forward, but approached the pile of stones.

When Su Yi swam to the stone, he found that it was indeed an animal, but it was not a big fish, but a whale, which made him very interesting.

Next, he grabbed the stone with one hand and observed the whale with the other.

This whale is about two meters long, the head is slightly rounded, with an inconspicuous beak, the body is two-colored, black and white, this surface looks smooth, it has a lot of wounds on its body, I don't know how it came about, part of the injury, it should be injured by the struggle of the stone card owner, it looks like the injury is very serious, and now it doesn't even have the strength to struggle, and it is dying.

After observing for a while, Su Yi realized that this was not an ordinary whale, and judging from these characteristics, he thought it was a killer whale, a juvenile killer whale baby.

The killer whale, also known as the orca or killer whale, is a large toothed whale and the largest species in the dolphin family.

The adult killer whale is 8~10 meters long, weighs about 9 tons, has a slightly rounded head, has an inconspicuous beak, a high and erect dorsal fin, bends up to 1 meter, a black and white body, two wing bones far apart, a large temporal fossa, a slender mouth, and sharp teeth.

Killer whales are carnivores, they have a fierce temperament, and are good at attacking prey, they are natural enemies of penguins, seals and other animals, and sometimes they also attack other cetaceans, even great white sharks, in the ocean, can be called overlords.

In their natural state, killer whales have a lifespan similar to that of humans, with males living 50-60 years and females living 70-80 years.

For killer whales, Su Yi is full of curiosity and wants to see it with his own eyes.

Although some aquariums have killer whales, it is the first time he has seen killer whales in person when he has grown so big, and in the past, he only learned about killer whales through television, the Internet and other carriers.

This time, Su Yi found a killer whale here, which still surprised him. (To be continued.) )
