But soon, Li Xuan discovered that he was overly worried.

The quality of this diving equipment is really beyond words.

Moreover, the strong pressure of sea water at a depth of about 300 meters will cause huge damage to the human body and will directly cause irreversible permanent damage to the internal organs of the human body. However, it is really not a matter for the alloy materials and synthetic rubber that make this set of deep-sea diving equipment.

According to relevant scientific research, humans can reach more than 11,000 meters under the sea.

This is the deepest place on the planet, the Mariana Trench.

As far as Li Xuan knows, the pressure in the deep sea is very high, and the closer it is to the seabed, the greater the pressure.

The pressure on the seabed will have a very terrible impact on the human body. It will not only affect human hearing, but also the body's blood circulation, muscles, retina, brain, etc. will be subject to pressure and lead to imperfect blood circulation.

Moreover, the terrifying pressure of the deep sea will greatly affect people's hearing. In the past, many people who have been engaged in deep sea diving operations for a long time had symptoms of deafness in both ears.

The seabed, which is 300 meters deep, can definitely be regarded as the deep sea.

Li Xuan was very sure that if he hadn't worn this diving suit, he would definitely be bleeding from his seven orifices now.

But with the protection of this deep-dive equipment, Li Xuan did not feel the slightest pressure brought by sea water.

"Hey, Brother Li, Li Xuan, can you hear it?" At this time, Fatty Wang's voice appeared in the breathing helmet again.

"You can hear it, you said." Li Xuan looked around and spoke.

To be honest, Li Xuan was not very comfortable in his heart.

Under such deep water, light basically won't appear here.

Under this deep pool, it was basically pitch black and there was no sight of five fingers.

Moreover, the sea water in this deep pool is different from normal sea water, and it does not flow.

Deep, dark, and closed, Li Xuan couldn't stop feeling shivered in his heart.

In this environment, if you stay for a long time, it will have a great impact on people's hearts.

At this time, Fatty Wang's voice made Li Xuan feel particularly friendly, and he felt the urge to chat with him more.

"Ha, it's okay, I just want to chat with you." Fatty Wang's voice sounded again, "Do you feel okay now at the bottom of the water?"

"It's pretty good." Li Xuan smiled on his face. There was a voice in his ear under such deep water. It felt so good.

"It's good. You can move around under the water and try the effect of this set of equipment." Fatty Wang said happily.

Li Xuan nodded softly, looked around him, but he thought about the actual effect of this deep diving equipment.

Li Xuan suddenly realized that he could not use such an advanced set of diving equipment.

In such a deep sea water, even if Li Xuan took the crew to the bottom of the sea and was able to move flexibly, he seemed to be unable to perform underwater operations normally.

It’s not that fishery resources are no longer abundant under such deep sea water.

Under this deep sea water, fishery resources are very rich, and most of them are rare fish, and each one is expensive.

But at this depth, there is no light. Even if a sea area swims past the divers, it is generally difficult for divers to discover it.

According to the division on the ocean, the area with a depth of no more than 200 meters is a marina, also known as a photosynthesis belt.

At this depth, the sunlight can effectively pass through sea water, and the plants in it can perform photosynthesis.

It is estimated that microorganisms floating on the sea produce half of the Earth's oxygen.

For ocean areas with a depth of more than 200 meters, they can be called the deep sea.

The average depth of the global ocean is about 3,800 meters, which is about the same height as Mount Fuji.

Humans have only reached the bottom of less than five percent of the sea area.

Usually humans swim in the sea within three meters of depth, which is a casual scuba diving.

Generally, even professional divers have a maximum diving depth that will not exceed forty meters.

According to physiologists' calculations, if you have received professional training in diving, the limit of diving depth is about 120 meters.

Of course, this is a general situation, and some talented people cannot be counted.

Deep diving is a huge challenge for humans, because the human body's ability to withstand pressure is limited.

Without equipment, a man named Herbert Nich set a world record, with a diving depth of 113 meters.

With equipment, the deepest record of diving in Amedgapur is 332 meters.

This depth is about the same height as the Tokyo Tower.

The normal diving depth of the submarine is 300 to 500 meters, which is also the depth of the safe sinking of the atomic submarine.

At this depth, only about one percent of the sun's rays can be reached.

It's a completely dark world.

This completely dark world is also a very mysterious world, with too many unsolved mysteries, even today's scientists still seem as incredible as a fantasy.

At a depth of one thousand meters, sea water can compress the volume of wood to half of its original size.

At this depth, it is said that the habitat of giant octopus will begin to appear.

The area of ​​depth used to be three hundred meters was the habitat of goblin sharks, and they are said to be deep-sea demons, and ecologically they are still a mystery to this day.

The deep sea with a depth of 1,700 meters can be even more surprising.

Southern elephant seals are said to be able to dive into this depth of water to find food.

The southern elephant seal is the largest seal in the world. It is a giant animal with a maximum length of about seven meters and a weight of five tons. It is said to be able to reach five tons and has excellent diving ability.

If someone dives three thousand meters below the sea, he will enter a new level.

The sea water pressure at that depth was above 300 atmospheres, and the deep-sea fish swimming almost disappeared.

But sperm whales can penetrate to that depth.

Sperm whales are the most extensive whales in the deep sea, and they spend two-thirds of their entire life in the deep sea.

It is a mystery to why sperm whales can dive so deep under the sea without being affected by the pressure of sea water.

But some people have raised the possibility that the sperm whales will take many long deep breaths during their float until their blood and muscles are filled with oxygen, and then they will start to dive slowly so that their internal and external pressures will remain consistent, and they will not bear strong water pressure in the deep sea.

But this assumption was not unanimously recognized by everyone.

Because there is a confusion, it is very difficult to explain.
