As robotic arm operators and submarine pilots, Hong Tao and Lada are certain to join the underwater exploration team. No one else has played much with this small submarine, and Lada and Hong Tao have been driving for two years, especially the technology of controlling a pair of robotic arms, Hong Tao said that no one dared to say the first. Catching crabs and lobsters with a robotic arm at the bottom of the sea every day has allowed Hong Tao to practice this skill perfectly.

In order not to attract the attention of the islanders, the Mouse Superman did not approach the sea area where the gold coin was found, and anchored at the mouth of Asaro Bay 7 or 8 kilometers away, and still used the modified patrol boat to drag the small submarine to find a predetermined area according to the coordinate position recorded on the GPS, and the small submarine dived first to determine the exact location, and after putting the float up, Dan and Jim then wore diving gear and dived along the rope of the float.

In fact, even without the guidance of GPS coordinates, Hong Tao can still find this piece with the help of the surrounding landmarks. This area is only a little more than 500 meters away from the main island of Salvora, and less than 100 meters next to it are two large reefs that have been hit by a strong crosswind. As for being so close to the island, why no one survived, it was possible that the time when they hit the reef was at night, most of the people were resting in the cabin, and the impact was too violent, the ship sank directly, and there was no chance for the people on board to escape.

But why 7 or 8 ships are missing here, then Hong Tao can't find a reasonable explanation, even in the 18th century, every ship had a huge oil lamp hanging on the stern bow, like the Spanish galleon, when a ship with a displacement of 4 or 500 tons was moving. At least a few hundred meters away, no matter how bad the weather is. The front has lost its marker light, and the ships behind should always see and dodge.

It was hundreds of years ago. It's too difficult to find the truth, and any small accident can cause completely different consequences, and that's what it means by a fraction of a millimeter. Now the important thing is not to analyze how the fleet sank, but to salvage one or two pieces of evidence about the fleet, only then can you apply for a salvage permit, otherwise everything will be in vain.

"Alright, cast the float, tell the above. There are modern shipwrecks underwater, don't bring metal detectors, that thing is useless, just come down with a ducted fan, and we have to dig more than a meter thick sediment to see below. Soon, the small submarine came to the side of the big pit from yesterday, and there was no dense shell-like object at the bottom of the pit, and in the course of one night, a thin layer of sediment had been covered on it. The currents here are strong. In addition, there is an estuary of a freshwater river in the bay, so the sediment content in the sea is very high.

When the float was raised, the antenna of the small submarine was also brought up, so that the submarine and the mother ship could communicate by radio. While waiting for Dan and Jim to get into the water. While telling the elder brother of the Puyol brothers how the gold coins were found, Hong Tao used a robotic arm to drive away the mud and sand, revealing the shell-like object underneath. Due to the loss of the air supply of the mother ship to the small submarine. So in order to allow it to stay underwater a little longer, except for the Rada and the Hongtao. Only Puyol's brother was with him, and he mainly provided Hong Tao with the necessary historical knowledge. By the way, Hong Tao is prevented from treating these ancient treasures in a rough way. Four or five of the gold coins salvaged yesterday had serious scratches and even chips, all of which were punctured by chisels on the mechanical arm, and the Puyol brothers were distressed for a night.

Soon, two humanoid objects with round heads and round brains, round hands and round feet descended the rope like a weighing stone. This kind of deep diving equipment is like wearing a spacesuit, heavy iron shoes and waist weights make the diver able able to walk very steadily underwater, and is not afraid of any sharp object stabbing the body, big iron shoes step on, everything is a floating cloud. Moreover, this deep-diving device, like a small submarine, is connected to the snorkel through the mother ship, and as long as the temperature and physical strength are sufficient, in principle, it can work underwater indefinitely. But this is also its biggest drawback, once the snorkel is entangled, then the diver is finished, he can't swim, and the equipment is too heavy.

"Jim, get rid of this gold and see how many of them there are, maybe you can find evidence here. Hong Tao was already able to communicate with the two divers by radio.

"This wreck is too much of a hindrance to be scanned with magnetic force, only by hand. Dan and I are going to probe the range of metal objects under the mud, and the task of digging the pit is up to you, dig lightly, and don't hurt the items again. "Jim and Dan only have a portable metal detector and no digging equipment, and they don't seem to be very interested in digging, and are more interested in comprehensive detection.

"Leave it to me, I'll be good at digging pits!" Singh, put down the snorkel and watch my brother dig treasures for you!" Hong Tao likes this task the most, what is it like to explore blindly through a lot of mud and sand, it is better to take care of what is in front of you, how much to get up, whether he is legal or not.

This time, Hong Tao found a good way, he didn't use any ducted fans to blow away the sediment, and directly used the snorkel of the small submarine. It's much easier to use, and the high-pressure airflow is much stronger and more powerful than the water flow of the ducted fan. You only need to use the manipulator to grasp the metal interface of the snorkel, and then it is like a water spray gun, pointing where to spray, where to spray the sediment and get out, the power is all controlled by the pressure of the compressor on the Singh mother ship, the pressure is maximized, and the hull of the iron ship next to it can be sprayed to pieces, which is very fun.

"It's too much pressure! It's too much pressure! Miss Singh, take the pressure down a little more. Unfortunately, with Puyol, the old man, Hong Tao couldn't enjoy the pleasure of spraying anywhere, he radioed Singh, and lowered the air pressure again and again, and finally the air flow in the snorkel was only enough to blow up the sediment layer by layer, and it was very slow to clean up. But just like that, Puyol was still too stressed, so he put his face against the observation window and stared at the mud and sand that was washed up by the air current, for fear of missing any small objects.

If you look down from the water, the patrol boat anchored below the sea surface is like a monster, the turbid sea water keeps tumbling, mixed with a large number of bubbles, through the sun's light, you can also see a thick cigar-like figure, waving two arms, dangling under the water, like a big lobster. The clean-up work was carried out until noon, the original 3 or 4 square meters of the big pit was expanded to more than 20 square meters by the flood, the east side has been dug to the side of the wreck, can no longer dig in, the west side dug 2 or 3 meters away, there is no object below, the shell-shaped gold coin is almost next to the side of the wreck.

Seeing that there was no gain further west, Hong Tao simply continued to dig in the north and south directions, digging a round pit into a long strip. Not to mention, Hong Tao is still very strong in hands-on ability, and his judgment is accurate, when this 3 square meters of gold coin layer is all cleaned out, and then dig south, what appears is not a shell-like gold coin layer, but some cylindrical objects, and a lot of small watermelon-like semicircles.

"Damn! This isn't an egg laid by the opposite sex, right? Puyol, why don't we cut off those gold coins and go, in case these eggs are broken, as soon as the big opposite sex comes out, we will all be finished!" Hong Tao didn't dare to blow those round things with air currents anymore, the eggs laid by alien creatures in science fiction movies were exactly the same as these things, and he panicked when he looked at them.

"Scientists believe in this kind of thing?" Pujol listened to Hong Tao's words and pondered for several seconds before determining what Hong Tao was talking about.

"Scientists aren't saints...... What do you think of those?" Hong Tao's face was rare for a few milliseconds, and he kept saying that he was Hong Taostan, but this time he was a little timid.

"That's about 20 pounds of shells! Looks like we've got a catch, let's see if we can get them out, but for God's sake, don't touch them with your big claws, don't touch them at all!" Pujol glanced at Hong Tao, and instructed Hong Tao in disgust what he should do and what he should not do.

"Puyol, you just met me in the state of a scientist, if you met me in the state of a businessman and in the state of an athlete, you would have been floating in the sea by now! I don't care about you, who made you old. Hong Tao wanted to reach into the cabin with a mechanical hand and catch the old man out to wash his brain with high-pressure airflow, but for the sake of the overall situation, he still held back. Although these two old men speak hard to hear, they do have some real talents.

Under Puyol's supervision, Hong Tao used a mechanical hand to hold the snorkel and carefully blow away the sediment in the middle of the pile, because the air pressure was not large, he had to clean it up little by little, and tossed for an hour to make this pile of debris roughly show their original shape.

According to Puyol, it should be a 6-inch cannon, which was the main gun on Spanish galleons at the end of the 17th century, and could fire 24 Spanish pound shells, and the weight of the gun itself was about 5,000 Spanish pounds, which was about 2,000 pounds and about 1,000 kilograms.

A bunch of eggs of the opposite sex don't need to be said by Puyol now, Hong Tao can also see that these are not eggs, they are too round. A few jars of pickles, Puyol judged to be containers of water or oil on board. There's also a larger, metal birdcage-like thing, more than half of which is buried in the mud and sand, which Puyol recks to be a ship light. From this, he further judged that this piece should be the stern of the ship, because the ship lights are usually hung on the stern, whether it is as he said, it will have to wait for large-scale excavation.
