Dragon Palace on the sea, under the Moon Pool.

A huge ring light illuminates the seabed dozens of meters deep as day.

More than a dozen divers, operating a variety of equipment, are constantly busy at one of the three shipwrecks.

And beside them, there are even more men, who are not wearing any protective or diving equipment, and only have a pair of coarse cloth shorts on their bodies, shuttling underwater like swimming fish.

These people were all crew members from Zheng He's fleet.

Many of the crew members who arrived through the "backstage passage" of the Dragon Palace on the sea were once fishermen and pearl divers.

For them, even if it is not in the case of this system projection, diving to a depth of tens of meters is as simple as eating a side dish, but it is more troublesome to need to surface and dive frequently.

And now, in essence, they are just projections, they can not breathe, they don't have to worry about the water pressure, and they are almost unharmed, so that they are full of energy underwater.

How deep can humans dive without wearing a compression suit?

It can be surprising to say it.

Diving without wearing a compression suit or carrying scuba or other equipment is called freediving.

The current human record for freediving depth is 214 meters.

Yes, humans can dive to more than 200 meters with their own bodies.

Freediving is the only way to dive without any restrictions, fast dives and quick ascent because if you inhale compressed air under the seawater, the strong air pressure can blow up the lungs and boil people's blood when they rise.

And all this is thanks to human instinct.

When the upper part of the lip is immersed in water under the nose of a human being, it opens up a "diving reflex" in human evolution, or in the evolution of all mammals.

The body automatically adjusts to a state suitable for underwater survival.

Blood begins to supply rapidly to the backbone of the human body, such as the brain and heart, and other internal organs, while reducing the supply to the limbs.

Perhaps, this is the reason why washing your face with water can make you feel refreshed, because your body thinks you are diving, and it will supply a lot of blood and oxygen to the brain.

The ocean has always been dangerous for humans. Parents will also tell their children that water is dangerous and should not be approached easily.

But perhaps, humans are closer to the ocean than they think.

Moreover, the speed at which humans swim underwater is also greater than the speed on the surface of the water, because there is no wave resistance.

If someone looks from above, they will see the dozens of people at the scene, like mermaids, swimming in the water at an astonishing speed.

Its free attitude and swimming speed make other divers feel particularly envious.

They themselves, dragging heavy ropes, wearing bloated costumes and compressor tubes, were hung in the water.

Even so, they can't stay underwater for long.

Human beings can stand at the top of the earth's ecology because they are a terrifying machine with super perfect evolution, not because of the combat power of modern otaku with 0.5 geese.

In many fields, human regulation and control are far more reliable than equipment.

Under the efforts of these dozens of people, a shipwreck that has been buried for more than 2,000 years has been buried under the water, in the mud and sand, and the attachments around it have been emptied.

A wreck falls silently into the water.

After 2,600 years, the structure of this wreck is still intact, although the hull has been damaged, but the structure of the entire ship has hardly been damaged.

There aren't even many signs of decay.

One message after another came back.

"The main structure is complete. ”

"The keel is not broken. ”

"The outer wall is broken, the bottom is broken. ”

"Partial repair and reinforcement ...... using foam material"

"The internal sediment is seriously blocked, and the feasibility of floating the pontoons is being evaluated. ”

"The internal sediment is too heavy, and the floating of the pontoon may affect the hull, so it is recommended to use foam material to float up. ”

In the Dragon Palace on the sea, in a room behind the Moon Pool, Pan Guoxiang looked at those people in groups, as if they were on the shore, cooperating and cooperating, operating various modern instruments a little clumsily, and constantly evaluating in his heart.

The kind of foaming material invented by Gu Xiaobai before is most suitable for underwater operations.

The material is ultra-light, the strength is good, it can be used directly underwater, and it can protect the hull itself, and it will not be like many pontoons floating up, but will destroy the hull.

The operation at tens of meters underwater is very covert.

And at this moment, everyone in the Sea Dragon Palace was attracted to the sea by Gu Xiaobai's gaze, and no one noticed that some magical operations were being carried out under the sea.

Even if there is any noise under the surface of the water, it is directly covered by the light and shadow sound effects of the Dragon Palace on the sea.

At this moment, Wang Guanshan issued a warning: "Report, Indonesia's 357 warships are approaching!"

"Stop them from approaching. Pan Guoxiang frowned deeply.

Gu Xiaobai needs to perform live, and the heavy responsibility of directing the salvage falls on his shoulders.

It's a pity that he is not an expert in deep-sea salvage, although the profession is a little bit touched, but in the past few months, he has also been under a lot of pressure.

Fortunately, as a scientific researcher, the most powerful ability is not the amount of knowledge you have, but the ability to quickly learn and quickly change your knowledge system.

Within a few months, he had devoured all the papers he could find on deep-sea salvage, and was finally up to the task.

However, if at this time the Indonesian warships approached and discovered their secrets......

Fortunately, after a few minutes, Wang Guanshan reported: "The 357 ship has left. ”

Before Pan Guoxiang could breathe a sigh of relief in his heart, he heard another heart-beating voice: "A helicopter of the Indonesian Navy is approaching ......"

Could it be that the people of Indonesia have discovered something wrong?

Or is it ...... The attack just now finally caused trouble?

For Pan Guoxiang, Gu Xiaobai was shot, and his first concern was Gu Xiaobai's safety.

But after that, their biggest concern was that it might affect the salvage plan.

If the military police of the other side are stationed to investigate the matter, the impact on the salvage is immeasurable.

Under the investigation of the other party's military and police personnel, how can the Dragon Palace on the sea transport this sunken ship out with a swagger!

Fortunately, after a while, Wang Guanshan said: "The other party has landed on the deck of the 357 frigate. ”

Pan Guoxiang breathed a sigh of relief again.

After such a back and forth, Pan Guoxiang felt that his kidney stones were about to be committed.

Time passed minute by minute, and finally, Pan Guoxiang received the happiest feedback.

"You can float. ”

"It's all right, it's all set!"

Pan Guoxiang raised his head and looked at the other monitor in front of him.

Then he said in a low voice: "Xiaobai, it's ready, and you can float up at any time." ”

Then he paused again and said, "Xiaobai, it seems that the 357 ship is still monitoring us......"

At this time, Gu Xiaobai is performing "Champion Overture" and "Departure Song".

Hundreds of horses danced with swords, and the men separated, the men gathered, and the men rushed to kill each other, and everyone was staring at each other.

It's as if they've been brought into the battlefield thousands of years ago.

I can't wait to be a knight and gallop across the field.

waited until the song "Departure Song" was sung, and Gu Xiaobai's voice came.

"Leave it to me. ”
