Chapter 921 Underwater Excavation
Sea Dragon Palace, under the moon pool.

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

More than a dozen divers, operating a variety of equipment, were constantly busy at one of the three sunken ships.

And beside them, there are even more men who don't wear any protective or diving equipment, and only have a pair of coarse cloth shorts all over the body, shuttling through the water like fish.

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

Many of the crew who arrived from the "backstage channel" of the Sea Dragon Palace were fishermen and pearl divers.

For them, even without the projection of this system, diving to a depth of tens of meters is as simple as eating a snack, but it is more troublesome to go up and down frequently.

But now, they are essentially just projections, they don't need to breathe, they don't need to worry about water pressure, and they are almost invulnerable, which makes them very motivated underwater.

How deep can humans dive without a pressure suit?
It might come as a surprise to say so.

Diving without wearing anti-pressure suits and without carrying scuba equipment is called free diving.

The current human free diving depth record is 214 meters.

Yes, human beings can dive down to more than 200 meters with their own bodies.

Freediving is the only way to dive quickly without any restrictions, because if you inhale compressed air under the sea water, the strong air pressure can blow up your lungs when you float up , making people's blood boil.

And all of this is due to human instinct.

When the upper part of the lip, under the human nose, is submerged in water, it turns on a "relic" of human evolution, or a "relic" in the evolution of all mammals-the "diving reflex".

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

Blood began to be rapidly supplied to the main parts of the human body, such as the brain and heart and other internal organs, while the supply to the limbs was reduced.

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

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

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

Moreover, the speed of human swimming underwater is also faster than that on the water surface, because there is no wave-making resistance.

If someone looked from above, they would see the dozens of people at the scene, like mermaids, swimming back and forth underwater at an astonishing speed.

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

They themselves, dragging heavy ropes, wearing bulky suits and compressor pipes, hang 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 human beings are a super-evolved horror machine, not because of the 0.5 goose fighting power of modern otaku.

In many fields, human beings' ability to regulate and control themselves is actually far more reliable than various devices.

With the efforts of these dozens of people, a shipwreck that has been buried underwater for more than 2000 years has been buried under the water, and all kinds of sediment have been emptied.

A sunken ship fell silently into the water.

After 2600 years, the structure of the sunken ship is still intact. Although the hull has been damaged, the structure of the entire ship has hardly been damaged.

Not even much sign of rot.

A piece of information was fed back.

"The main structure is complete."

"The keel is not broken."

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

"Foaming material is being used for partial repair and reinforcement..."

"The internal sediment is seriously silted up, and the feasibility of floating the buoy is being evaluated."

"The internal sediment is too heavy, and the floating of the buoy may affect the hull. It is recommended to use foam materials to float."

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

The foam material that Gu Xiaobai invented before is most suitable for underwater operations.

The material is ultra-light and has good strength. It can be used directly underwater, and it can protect the hull itself, instead of floating up like many buoys, which will damage the hull instead.

The operation under tens of meters of water is very concealed.

But at this moment, everyone in the Sea Dragon Palace was attracted by Gu Xiaobai to the surface of the sea, and no one noticed that some magical operations were going on under the sea.

Even if there was any noise under the water surface, it was directly covered by the light, shadow and sound effects performed by the Dragon Palace on the Sea.

At this time, Wang Guanshan issued a warning: "Report, Indonesian warship 357 is 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 he is a little bit professional, he has been under a lot of pressure in the past few months.

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

Within a few months, he gnawed through all the papers he could find on deep-sea salvage, and was finally qualified for the salvage task.

However, if the Indonesian warship approaches at this time and discovers their secret...

Fortunately, after a few minutes, Wang Guanshan reported: "Ship 357 has left."

Before Pan Guoxiang breathed a sigh of relief, he heard another heart-pounding voice: "A helicopter from the Indonesian Navy is approaching..."

Did the people in Indonesia find something wrong?
Or... the attack just now finally caused trouble?

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

But since then, their biggest concern is that this may affect the salvage plan.

If the other party's military and police stationed in to investigate the matter, the impact on salvage would be immeasurable.

Under the investigation of the other party's military and police personnel, how can the Sea Dragon Palace transport this sunken ship swaggeringly!

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

Pan Guoxiang breathed a sigh of relief again.

After doing this again and again, Pan Guoxiang felt that he was about to suffer from kidney stones.

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

"It can float."

"Okay, everything is ready!"

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

Then he said in a low voice: "Xiaobai, I'm ready and can go up at any time."

Then he paused again, and said, "Xiaobai, Ship 357 seems to be watching us..."

Right now, Gu Xiaobai is performing "Champion Overture" and "Expedition Song".

Hundreds of horses danced with swords, separated suddenly, gathered together, rushed to kill each other, and everyone watched intently.

As if, it has been brought into the battlefield thousands of years ago.

I wish I could become a knight on horseback and gallop across the battlefield.

Gu Xiaobai's voice didn't come until the "Song of Expedition" was sung.

"Leave it to me next."
