Live Streaming: Great Adventure in the Wilderness

```

The sea left behind white foam as the tide receded.

At 10 PM, for this relatively traditional town, few people could be found near the coastline, let alone the rocky area away from the beach.

Bi Fang stood atop the towering cliff, looking down at the dark grey sea that undulated rhythmically, masses of water slowly bulging and then receding as if a terrifying sea creature was stirring up the waves beneath the surface.

Waves several meters high crashed against the cliffs below his feet while the distant lighthouse monotonously swept its light across the sea surface.

With the help of Mandy and Keke, Bi Fang struggled to put on his diving suit and flippers, then took a detour to enter the shallow sea from beneath the cliff.

The mission was for Bi Fang and Mandy to set up underwater cameras while Keke kept watch and stood guard onshore.

Mandy, donning goggles, joked, "I thought you were going to leap straight down from up there, like a movie protagonist diving into the sea from a cliff and miraculously surviving."

"You seem to have some misconceptions about me."

Bi Fang rolled his eyes as he bit down on the breathing valve.

This was not a live broadcast and the situation was not dire; there was no pursuit of cinematic effects, nor was there a need for it. Only a fool would risk jumping into the sea—wasn’t it more pleasant just to enter the water in the ordinary way?

"Sorry, you’ve always struck me that way, like... um, a kind of one-man-hero movie?"

"Instead of talking about this, save some energy for the dive. We only have two oxygen tanks, and you’re not Bajau," said Bi Fang, no longer engaging in the conversation, as he plunged into the great ocean.

To facilitate carrying supplies, the two of them didn’t have many oxygen tanks, just two each. This required them to act quickly and decisively.

"Bajau people? What is that?" Mandy suffered from his lack of knowledge.

Bi Fang didn’t explain and simply swam downward.

The potential of humans is truly a mystery sometimes.

In the classic novel "Water Margin," "White Stripe in the Waves" Zhang Shun and "River Overturning Mouse" Jiang Ping from "The Three Heroes and Five Gallants" were able to lurk underwater for days. Even strong men like Li Kui and Bai Yutang would be pulled underwater by them and, with their bellies full of water, had no choice but to disarm and surrender.

Lurking underwater for days and nights was an exaggeration by ancient literati.

Without diving equipment, ordinary people couldn’t stay submerged for more than two minutes. Even now, Bi Fang, without any auxiliary equipment, could only move about for about five minutes.

However, the Bajau people living in Southeast Asia, wearing just a pair of goggles and without any other apparatus, can dive dozens of meters deep to fish or collect pearls, staying submerged for over five minutes, sometimes even as long as fifteen minutes.

With this ability, the Bajau have lived on the sea for a thousand years, using boats as their homes, relying on fishing for a living, and rarely setting foot on land.

"Bajau" in the Indonesian language means "People of the Sea."

If it is nonsense to say that Sherpa people have an extra lobe in their lungs, it is indeed true that the divers among the Bajau are born different, as their spleens are 50% larger compared to other populations.

When they dive into the water, their spleens contract, squeezing the oxygen-rich red blood cells into their vessels, increasing their blood’s oxygen content by up to 9%, thereby extending their diving time.

Theoretically, the larger the spleen a creature has, the more advantageous it is for diving; deep-diving seals, for instance, have spleens that comprise a larger proportion of their body than other animals.

The exceptionally large spleens of the Bajau aren’t the result of training through diving.

Even among the Bajau who don’t dive, their spleens are larger than those of other ethnic groups, a characteristic determined by innate genetics.

The Bajau have a mutation in their PDE10A gene, which causes an increase in the level of the thyroid hormone T4 in their body. This hormone promotes the growth of the spleen, thus endowing the Bajau with extraordinary diving capabilities.

Bi Fang felt that, with the System’s capabilities, perhaps he could also undergo such an enhancement.

Maybe he would be the future world diving champion.

Seeing that Bi Fang had no intention of explaining, Mandy shrugged, "Ah, sometimes I really envy you natural-born divers. Unlike me—I have to keep working hard to become a world champion."

"Get down there," Bi Fang replied.

Keke, seeing Mandy was fully geared up, kicked him in the buttocks and forcefully sent him into the water.

With a splash, a heavy object entered the water.

The cool sea instantly enveloped him. Bi Fang opened his eyes and turned on the headlamp, his vision filled with the silver reflections of bubbles.

Bi Fang tightened his core, his body moving up and down like a fish, rapidly diving into the water without even fluttering his flippers.

Diving is a feeling hard to describe. What makes people like diving?

Each person’s answer might be different.

Some are fascinated by the colorful marine life in the ocean.

Some enjoy the sensation of weightlessness under neutral buoyancy.

Others take pleasure in drift diving, flowing with the currents.

Some like the adventure of exploring historical relics on the dark ocean floor.

Or perhaps it’s just a simple quest for thrills...

But for Bi Fang, while there is plenty of land to travel on Earth, over 70% of the ocean has never been set foot in by many people.

Diving gave him a way to explore this new world.

```

Perhaps, this one answer was already enough.

Underwater was very quiet.

The only sound that could be clearly heard was perhaps the bubbles made by one’s own breathing.

The ocean at night, without direct sunlight, the flashlight could only illuminate up to six or seven meters, the surroundings were dim.

Underwater, all of a person’s sensory abilities were reduced, visibility in the water was very low, the nose was covered by the goggles, unable to speak, hearing almost nothing.

As the beam of light swept over, tiny silver fish swiftly swam away, leaving only a trail of bubbles.

Mandy had rarely experienced this, or rather had never experienced it, performing some kind of task like a special forces soldier, even though he had dived thousands of times, he still felt an indescribable emotion surfacing in his heart.

What surprised him even more was Bi Fang beside him.

Even though it was pitch-dark all around, the other person seemed to have grown an extra pair of eyes, even managing to avoid the coral reefs that hadn’t yet appeared in the light!

Mandy was very certain that, ten seconds before, Bi Fang had preemptively avoided a coral reef that hadn’t yet appeared!

Damn it!

Bi Fang didn’t know what Mandy was thinking, but he indeed had an extra pair of "eyes".

Shark’s electroreception was too fucking useful in the sea!

In the 1960s, scientists tagged sharks with sensors for the first time, letting humans understand information such as the speed and location of sharks.

But what surprised the scientists the most, without a doubt, was that many sharks were able to accurately find their way in the deep sea where one couldn’t see their hand in front of their face.

The reason was the sharks’ magnetic reception ability.

The shark’s head had tiny protrusions that could sense the slightest changes in the underwater electric field.

Inside their bodies were small particles of magnetic minerals, very similar to the material of a compass, which could sensitively detect the Earth’s magnetic field.

Since a certain ocean survival mission, Bi Fang had also acquired this ability, of course, not as good as the sharks themselves.

But no matter how weakened, the strength of this ability could not be denied.

However, for Bi Fang on land, it was difficult to feel the help brought by electroreception, only barely using the water molecules in the air to sense the activity of organisms within about half a meter around him.

But in the sea, this function surged dozens of times in an instant, Bi Fang was like a radar, able to clearly map everything around in his mind.

The light on his head was completely superfluous, he could feel any situation within ten meters!

There were many small fish living on the coral reefs at the bottom of the sea, and with these biological magnetic fields, Bi Fang could easily sense the existence of rock walls and reefs in advance, avoiding them.

This kind of behavior, in Mandy’s eyes...

So you’re not Superman, you’re the fucking Ocean King, huh!

As they descended over ten meters, Bi Fang’s body felt a bit cold.

Perhaps during the day this place was still warm, but now, the seawater was gradually cooling down.

The water resistance was great, but this couldn’t stop Bi Fang and Mandy at all.

Both were good swimmers and divers.

For most people diving underwater for the first time, this strange environment and sensation indeed made one very nervous.

It wasn’t just a psychological factor, but also a physiological reaction.

The world’s best divers, like New Zealander William Trubridge, could dive to a depth of 100 meters in one breath.

But even in 10-meter-deep water, a person’s lungs would be compressed to half the normal volume, and in 100-meter-deep water, the lungs were no bigger than two baseballs.

Athletes like Trubridge were able to dive so deep because humans have an innate ability called the "mammalian dive reflex".

This physiological reflex has another more poetic name, known as the "master switch of life".

The moment a person’s face is submerged in water, various physiological reflexes that are triggered in the brain, lungs, heart, and other organs.

The deeper the dive in water, the more pronounced these reflexes become, ultimately leading to physiological changes.

The blood inside the human body will start to flow from the limbs towards the vital organs, and in extremely deep water, the blood can even permeate the organ cell walls to support the organs, protecting them from imploding under great water pressure.

Moreover, as soon as one enters the water, the heart rate drops significantly, even if you exert yourself in the water, the heart rate is slower than on land, which means that you consume less oxygen in the water and can stay longer.

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

Ama divers in places like Japan use the "master switch of life" to perform deep dives.

At ten meters deep, the first line of photography could be arranged.

Bi Fang opened the bag he was carrying, made a gesture to start the operation, and then threw a rock-shaped camera to Mandy.

The two began installation, surrounding the rock layer.
