Live Wilderness Adventure

When the sea ebbs, white foam is left behind.

At ten o'clock in the evening, for this relatively traditional town, there are few people near the coastline, let alone the rocky area far away from the beach.

Bi Fang stood on the towering cliff, looking down from his position, the black-gray sea undulating, the tens of millions of tons of sea water slowly rising and gradually shrunk, like a terrifying sea beast stirring the wind and waves underwater. , making waves.

Several meters of waves crashed on the cliff below, and the light from the lighthouse in the distance swept across the sea monotonously.

With the help of Mandy and Keko, Bi Fang laboriously put on the diving suit, put on the duck webs, and then detoured from the bottom of the cliff into the shallow sea.

In this operation, Bi Fang and Mandy were responsible for the installation of underwater cameras, and Keke sent guards and guards on the shore.

Mandy put on his goggles and joked, "I thought you were going to jump directly from it, like the protagonist of the movie, jumping from a cliff into the sea and escaping death."

"You seem to have misunderstood me."

Bi Fang bit the breathing valve and rolled his eyes.

It's not a live broadcast, and the situation is not critical. One is not to pursue the sense of picture, and the other is that it is unnecessary. Only a fool will take the risk of jumping into the sea.

"Sorry, you've always felt like this to me, like... um, that kind of personal hero movie?"

"If you have time to talk about this, why don't you save your energy and go into the water. We only have two oxygen cylinders, and you are not a Bajau." Bi Fang didn't say more, and threw himself into the sea.

In order to facilitate the carrying of supplies, the two of them did not carry many oxygen cylinders, only one person and two, which required them to fight quickly.

"Bajau? What is that?" Mandy suffered the loss of lack of culture again.

Bi Fang didn't explain and went directly downstream.

There is something really a mystery about human potential.

Zhang Shun, the "white stripe in the waves" in the classical novel "Water Margin", and Jiang Ping, the "River Rat" in "Three Heroes and Five Righteousness", can hide in the water for several days, even if heroes like Li Kui and Bai Yutang are caught by them. Dragging into the water and pouring a belly of water will only turn you away.

It is an exaggeration of the ancient literati to hide in the water for days and nights.

In the absence of diving equipment, the average person will not spend more than two minutes lurking in the water. Even the current Bi Fang, without any auxiliary equipment, can only be active for about five minutes.

However, the Bajau people living in Southeast Asia can dive into tens of meters of water for fishing and pearling with only a pair of goggles and no other equipment. The diving time is more than 5 minutes, sometimes as high as more than ten minutes. minute.

With this ability, the Bajau have lived by boats at sea for thousands of years and fished for a living, and rarely set foot on land.

The word "Bajau" means "people of the sea" in Indonesian.

To say that the Sherpas have one more lung lobe than ordinary people is nonsense, but the Bajau who are good at diving are indeed born with an abnormality. Their spleen is 50% larger than that of other people.

When they dive into the water, the spleen contracts, squeezing the oxygen-containing red blood cells into the blood vessels, increasing the oxygen content of the blood by up to 9 percent, extending the dive time.

Therefore, in theory, the larger the spleen, the better the diving advantage. The spleen of the deep diving seal accounts for a larger proportion of the body than other animals.

The Bajau's extra-large spleen is not the result of acquired diving training.

Even the Bajau who do not dive have larger spleens than those of other races, which is genetically determined.

The mutation of the PDE10A gene of the Bajau can increase the level of the thyroid hormone T4 in the body, which can promote the enlargement of the spleen, so that the Bajau have extraordinary diving ability.

Bi Fang felt that with the ability of the system, it might be possible to give him this kind of reinforcement last time.

Perhaps in the future, the world diving champion will be himself.

Seeing that Bi Fang didn't mean to explain, Mandy shrugged: "Hey, sometimes I really envy you for being a natural diver. Like me, you can only win the world championship if you keep working hard."

"Come down for me."

Seeing that Mandy was well dressed, Keko kicked his **** and forced him into the water.

With a thud, the heavy object fell into the water.

The warm sea water instantly enveloped his body, Bi Fang opened his eyes, turned on his headlights, and his field of vision was filled with the silver reflections of bubbles.

Bi Fang tightened his waist and abdomen, moving up and down like a swimming fish, diving into the water quickly, without even stepping on the duck webs.

What is diving like and why do you like diving?

Everyone's answer may be different.

Some people like the colorful and different creatures in the sea.

Some people like the feeling of weightlessness under neutral buoyancy.

Some people enjoy drift diving with the flow.

Some people like to explore the historical relics of the dark seabed

Or simply seeking excitement...

But for Bi Fang, there are large areas of land on the earth that can be traveled, and more than 70% of the oceans have never been touched by many people.

Diving gave him a way to explore such a new world.

Perhaps, this answer is enough.

It's quiet underwater.

The only sound that can be clearly heard may be the sound of bubbles exhaling from his own breath.

In the ocean at night, there is no direct sunlight, and the flashlight can only shine at a distance of six or seven meters, and the surroundings are dark.

At the bottom of the water, all human sensory abilities will be reduced, the visibility in the water is very low, the nose is covered by a mask, cannot speak, and cannot hear any sound.

The beam of light swept across, and the tiny silver fish swam away quickly, leaving a piece of bubble water in the air.

Mandy rarely had such an experience, or had never experienced it, performing a certain mission like a special force. Even though he had dived thousands of times, he still felt an indescribable emotion floating in his heart at this time.

At the same time, what surprised him even more was Bi Fang on the side.

It was obviously dark all around, but the other party seemed to have opened his eyes extra, and he was even able to avoid the coral reefs that had not yet appeared in the light in advance!

Mandy is very sure that ten seconds ago, Bi Fang avoided the coral reef that had not yet appeared!

Hell!

Bi Fang didn't know Mandy's inner thoughts, but he did have an extra pair of "eyes".

The electromagnetic induction of sharks is so **** easy to use in the sea!

In the 1960s, scientists marked sharks with sensors, and for the first time let humans know the speed and location of sharks.

But what has surprised scientists most is that many sharks can find their way precisely in the deep sea where they can't reach their fingers.

The reason is the magnetic induction ability of sharks.

Sharks have tiny protrusions on their heads that sense the tiniest changes in the underwater electric field.

They will have some small magnetite particles in their bodies. These particles are very similar to the material of the compass and can sensitively feel the earth's magnetic field.

Since a certain marine survival mission, Bi Fang has also successfully possessed this ability. Of course, it cannot be compared to the shark itself.

But no matter how weakened it is, it cannot deny the power of this ability.

Bi Fang, who was only on land, usually had a hard time feeling the help of the shark's electrical induction. He could only barely use the water molecules in the air to sense the activities of living organisms about half a meter around his body.

But in the sea, this function skyrocketed dozens of times in an instant. Bi Fang was like a radar, which could clearly reflect everything around him in his mind.

The lamp post above his head is completely redundant, he can feel any situation within ten meters!

There are many small fish living on the coral reefs on the seabed. With the help of these biomagnetic fields, Bi Fang can easily perceive the existence of rock walls and reefs and avoid them in advance.

Such behavior falls in Mandy's eyes...

It turns out that you are not Superman, but the **** Sea King!

After sinking more than ten meters, Bi Fang's body felt a little cold.

Maybe it is still warm here during the day, but now, the sea water is gradually cooling down.

The resistance of the water is great, but it can't stop Bi Fang and Mandy in the slightest.

Both are good swimmers and scuba divers.

Most people are diving for the first time. This kind of unfamiliar environment and feeling really makes people very nervous.

Not only psychological factors, but also physiological reactions.

The world's best divers, such as New Zealander William Trubri, can dive to a depth of 100 meters in one breath.

But even in 10 meters of water, a person's lungs will be compressed to half of their normal volume. In 100 meters of water, a person's lungs are only the size of two baseballs.

Athletes like Trubri can complete such deep dives because humans have an innate ability called "mammalian diving reflex".

There is also a more poetic name for this physiological reflex, called the "Master Switch of Life".

When people bury their face in water, various physiological reflexes are triggered in the brain, lungs, heart and other organs.

The deeper you dive in the water, the more pronounced these reflexes become, ultimately triggering a physiological change.

The blood in the human body will start to flow from the limbs to the vital organs in the body. In extremely deep water, the blood can even penetrate through the cell walls of the organs to support the organs and protect the organs from implosion under strong water pressure.

Moreover, as long as a person enters the water, the heart rate will drop significantly. Even if you exercise vigorously in the water, the heart rate will be slower than when you are on land, which means that people will consume less oxygen in the water, and the energy in the water will be lower. Stay longer.

This is the real reason why humans can go deeper than 100 meters.

One of the ancient occupations in Japan and other places, "Ama", is to conduct deep diving by turning on the "master switch of life".

Ten meters deep, the first photography line can be arranged.

Bi Fang opened the bag he was carrying, gestured to start moving, and threw a stone-shaped camera to Mandy.

The two surrounded the rock formation and began to install.
