In the diving world, the highest record for a human dive was set by Egyptian Amund Jabbar in 2014 at a depth of 332 meters. It is also the deepest record for a human dive, and the sea above this depth is still a no-go zone for humans.

Therefore, deep-sea salvage is a completely different concept from shallow sea salvage.

At a depth of less than 100 meters, humans can rely on their own abilities to make various aids for salvage, but beyond this depth, everything has to rely on machines to work.

The seabed where the Mercedes sank was more than 1,920 meters deep, a depth that could not be infiltrated by the flesh, and all the work had to be carried out by two robots.

The two deep-sea robots are now responsible for most of the work tasks, and due to the constraints of charging work, the unmanned robots can work for 23 hours each time, but the manned robots only work for 15 hours.

Every time you work for such a long time, you need to go through eight hours of charging before you can carry out the next salvage.

In this case, the two most important positions of the whole ship are Zhou Minghong and Liang Hao, because only they can skillfully operate the two robots.

Although Zhou You also has the ability to operate robots, it is impossible for him to do it himself in order to catch up with the schedule, because this is completely unnecessary.

On May 6, after another test of the manned robot, Liang Hao sat in the robot.

With everyone's expectations, the salvage of the Mercedes officially began, and multiple cameras faithfully recorded this historic moment.

After fifteen minutes, the robot was released to the predetermined sea area, and the robot used the mechanical arm to remove the cable and counterweight, and fixed the main cable on a flat seabed not far from the Mercedes, and only a soft rope was left between the robot and the main cable.

When the manned robot entered the intended work area and began to cut the hull, another cable was lowered. However, instead of a robot, it is equipped with four one-cubic-meter cages welded with steel bars and wires.

The cage is welded with steel bars and then woven into a cage with a gap of no more than two millimeters around the steel bars. Even if it is a silver coin, it is impossible to leak out of the cage, but the liquid, of course, will pass through the gap.

Not only are the cages carefully woven, but they also have a sealed top cover, plus a clasp that is easy to close with the robotic arm to turn it into a sealed container.

The four wire cages were put down, and then the unmanned robot was put down, cooperating with the manned robot for salvage operations.

In terms of operation, unmanned robots are of course inferior to manned robots, because the price of the two robots is doubled, and the functions are far from the same.

So, manned robots will do some precision work, while unmanned robots will do some auxiliary work.

In order to facilitate salvage and save costs, even the Spanish experts did not think about keeping the hull of the Mercedes, because the wood had been decayed for more than a hundred years and had almost no preservation value.

The wood has rotted under the pressure of the change of pressure, even after it has been cut, before it has even surfaced.

The opening was opened from the belly of the ship, and before that, Liang Hao had already cleared the nearby sea mud and aquatic weeds, so although there was a lot of movement under the water, Liang Hao's every move could still be clearly seen through the camera.

Almost everyone's eyes were glued to the screen, and even environmental experts did not question his irregular behavior, expecting a major discovery.

The Mercedes' hull had completely decayed, and the cutter felt like it had been cut into the mud, and soon an opening of more than two square meters was made in the hull.

When the robotic arm pried open the hull, it was like a building block collapsing, and the hull collapsed in one fell swoop.

Fortunately, Liang Haocub was warned, and the parking position was relatively far away, and he turned on the power plant and retreated as soon as possible, so that he was not buried.

When the blisters and mud calmed down, everyone saw through the screen, and the vision was full of glowing silver coins.

In the workshop, all the Spaniards shouted, high-fived and hugged each other.

And in the main command cabin, they all cheered as well. Everyone understands that this time everyone is going to be developed.

The two robots worked together to begin to clean up the poured silver coins little by little, and the two wire cages were filled in a few moments.

Then the cages were covered, hung on a cable, and slowly hoisted up.

The salvage at the beginning is always the easiest, because the treasure at this time is like a newly developed mine, and the ore is just a hoe.

But later on, it will be slower and slower, because there will be fewer and fewer things, and there will be more time to look for than to work.

When the first batch of silver coins was salvaged out of the water, even Zhou You couldn't control his excitement and took most of the people to the workshop, waiting for the silver coins to come out of the water.

In the warehouse, the Spaniards are ready, and they have set up two airbag-shaped swimming pools next to the water outlet. Each pool is about 10 cubic meters, but instead of water, it contains special antioxidants.

After draining, the coins are poured into the first pool, soaked, then cleaned and cleaned, and in good condition, they are soaked in the second pool, and finally packed into a PVC plastic box that has been prepared for a long time.

If it is not in good condition, it will be marked, stored separately and then shipped back to Spain for further restoration work.

This kind of plastic box is still custom-made in Malaysia, a little smaller than the original porcelain box, but it is thicker, and can hold 100 kilograms of items without deformation.

According to estimates, a Spanish silver coin is about 30 grams, and this box can hold 1,000 pieces, and the weight is only more than 30 kilograms.

In order to preserve the silver coins in good condition, the Spanish side sent a team of nearly twenty people, who could not even interfere with the travel.

As the cable slowly rose, no one paid attention to the underwater situation, and they all ran outside to wait for the moment when the silver coin came out of the water.

The two cameras of the TV station were also pointed at the water outlet, looking forward to the moment from different angles.

Orti was the only one still talking, looking at the camera, excitedly introducing the equipment and arousing everyone in front of the TV.

When the two cages were hoisted, everyone couldn't help but start applauding and cheering, and two of the more emotional experts even couldn't hold back their tears, and they also attracted the attention of the two photographers and pointed the camera at them.

It is conceivable that after this moment, Orti will definitely interview them and enrich the video material.

After the coin was hoisted out of the water, the camera took pictures from all angles, and after about three minutes, the water drained a little before slowly leaving the spout and hoisting it next to the first antioxidant pool.

The staff unhooked the hook and began to use a small plastic dustpan to transfer the silver coins into the pool little by little.

If you follow the practice of traveling around, you will hang the hook directly at the bottom of the cage and pour the silver coins directly into it. But this will certainly not be agreed to by the Spanish side, because if a silver coin is damaged, it will cost more than a thousand dollars!

It took about twenty minutes, and a dozen staff members were exhausted and panting, to transfer all the two cages of silver coins into the pool.

Several experts couldn't wait to come to the pool, reached out and scooped up silver coins from the antioxidants, and looked at them obsessively in their hands.

Zhou You also wanted to get closer and have a look, but seeing that the camera had been shooting at them, Zhou You decided not to join in the fun.

However, Paris and Gracia had no such concerns, and the two of them, unable to resist their curiosity, ran to the front, and after obtaining their consent, one of them took a silver coin and admired it.

Buried underwater for nearly two hundred years, most of these coins are well preserved, but they all have green embroidery, which is really nothing to look at.

The two of them soon lost interest, returned the silver coins to them, and retreated to the side of Zhou You.

A photographer unconsciously pointed his lens at Gracia and Paris, two of them, one is a famous "entrepreneur" in Spain, and the other is a celebrity in the United States and even the world, both of whom are extremely beautiful.

The photographer was probably attracted to them and wanted to shoot more of their footage.

Although he knew that when editing, he had to have his own permission to make it, Zhou You still waved his hand and asked the photographer to turn the camera around.

If he secretly made a copy of these video materials and then secretly sold them, the impact would not be ordinary.

It is precisely because of the extraordinary identities of the two of them that some things cannot be left outside, even if they are known to everyone.

The photographer didn't know what the reason was, he didn't pay attention to the movements of the tour, and still shot at them. Zhou You found that he was still adjusting the focus, as if he wanted to shoot more clearly.

Zhou You's face sank, turned his head to look at Cai Zhongwei on duty, and glanced at him.

Cai Zhongwei immediately rushed forward and reached out to grab the other party's camera.

"What do you want to do?" The other party paused for a moment and shouted at Cai Zhongwei.

It's a pity that Cai Zhongwei doesn't even speak English, let alone Spanish. Seeing the other party yelling, he didn't care about 3721, kicked him in the stomach, and snatched his camera.

Everyone was stunned, and the experts frowned, not understanding what was happening.

Orti, who was interviewing an expert, turned her head to look at the photographer who had fallen to the ground and asked, "Mr. Zhou, what happened?" Zhou You beckoned her to come over. Then I turned on the playback function of this camera, and I saw that most of the shots were shots of Zhou You and two girls.

Her face stiffened, she looked sternly at the photographer and said, "Santos, I need an explanation." (To be continued.) )
