Once the areas of focus have been identified, a magnetometer is used to carefully search for those areas. Exact coordinates are marked where there is a metal reaction, and when all the key areas have been scanned, the diving equipment will be used. Divers will descend to these key areas and use portable metal detectors to carefully search square meter by square meter. Once a strong signal was found, it was possible to carry out a small-scale excavation to see if evidence of a wreck could be found.

After exploring all the key areas, if there is no evidence that can prove that there is a target shipwreck here, then it is necessary to analyze it again to see if there are any possible misses, and if possible, it is necessary to go and search carefully. If it has not yet been discovered, it is necessary to reconsider the reliability of this sea area, or expand the search area, or Mingjin will withdraw his troops and go back to continue the search for information, looking for clues from it, and see if there can be new discoveries and new clues.

It sounds like treasure hunting is a very exciting, fun, and mysterious job, and it really has to be done, and most of the time is no different from a field archaeology team or exploration team. Not to mention sleeping in the open and risking one's life, there is nothing to stimulate or be proud of in what you do every day. It is nothing more than putting away and putting down the towed sonar and magnetic array over and over again, putting the electric detonator into the rock layer on the seabed through a small drilling machine one after another, and then staring at the seismic wave feedback device and pressing the detonation button, and then inputting the obtained various curves and data into the computer, and generating a more intuitive three-dimensional image of the structure and texture of the nearby seabed piece by piece.

Hong Tao only endured it for three days before he got bored, he originally thought that this job was like 20,000 miles under the sea, and he could encounter countless new and strange things under the sea. But after tossing for several days, not to mention the novelty and weirdness. Not even a chance to dive. Every time I asked Jim, he said soon, soon. I don't know what his basic value of fast and slow is, if it is a year, Hong Tao is not going to wait.

That is to say, everyone else is busy with work, and it doesn't matter if you don't help yourself, you can't make trouble for others anymore, right? What can you do if you're bored? It's easy to do, happiness has always been found by yourself, and Hong Tao is not lacking in the spirit and means to find happiness. Isn't there no one to play with? yes, I'll play by myself. Take Lada, Singh and Levine, drive your own little submarine, and set off to explore the treasure!

For Hong Tao's behavior, which is equivalent to nonsense, everyone has no reaction. Jim had long expected that Hong Tao's mallet couldn't bear the loneliness, and it was already rare that he could endure three days without coming to give orders to everyone to make trouble, as for where he went and what he went, in addition to telling him about safety. No one cares, don't come back.

Compared to the sunny, calm Caribbean Sea, the North Atlantic, especially in winter, is hell. The wind is raging on the surface of the sea, and there are also undercurrents surging at the bottom of the sea. There are also countless tiny floating debris in the water, and visibility is very poor, if the lights are not turned on. At more than 20 meters underwater, you can't see objects 2 or 3 meters away. No wonder the divers didn't come down to search for it themselves, and it was in vain to come down. Even with the high-powered searchlights on the submarine turned on, the visibility was still less than ten meters. Divers certainly don't have such a large light to carry, and there are no snorkels to allow them to walk around the ocean floor without any worries. The main thing is the cold, the water temperature here is less than 10 degrees, and you can only stay in the water for 20 minutes at most to recover your body temperature when you enter the water in a thermal wetsuit.

No matter how bold Hong Tao is, he doesn't dare to drive the submarine around in this sea condition, the underwater current is too fast, and if the submarine is washed into some reef crack, it will be shrimp. His range of movement is limited to a range of 500 meters around the Mouse Superman, beyond which the snorkel and power supply cannot be obtained from the ship. Using the submarine's own electricity and oxygen, it was not enough for him to toss around at the bottom of the sea like a big crab picking up rags.

"Left! Left! Try this,! Who is so lacking in morality, throwing down all the broken tires, I don't know how to protect the environment!" It was Lada who drove the submarine, and it was Hong Tao himself who controlled the manipulator, and under his command, the small submarine was scurrying around the bottom of the sea. As long as he sees something that doesn't look like a natural object, he will go over and grab it with a manipulator and take a closer look, and put it in the salvage warehouse to take it back for study.

To say that the Spaniards are no better than the Chinese, there is everything on the bottom of the offshore sea, from shipwrecks and cars tens of meters long, to wine bottles and canning boxes, and there are basically things on land underneath, if you really pick up rags to sell, you can pick up a lot of them in an hour. Hong Tao did not tire of rummaging through these rags, and when he returned to the mother ship in the evening, he really picked up a lot of rags that he thought were worth studying and studying, and stuffed them all into the salvage warehouse and brought them back.

"This should be a lifebuoy on a sailboat, right? Look at the material is wood, this is the first time I have seen a wooden lifebuoy, is it possible that it was on a Spanish galleon in the 18th century?" After dinner, Hong Tao ran to the bottom cabin with his arms and sleeves rolled up to check the treasures he got back, and in order to accurately identify the age of the item, he also dragged Jim alive and dead.

"The lifebuoy wasn't invented in the 18th century, and it was first during the First World War. Jim was tired from a day, and he wanted to lean on the recliner and smoke Hong Tao's high-end cigar, drink Hong Tao's good wine, chat with his companions or read a book, but now he was pulled to see the tatters, and he was very unhappy. But he can't refute Hong Tao's face, who makes the family a major shareholder, if he is unhappy, maybe the standard of food will drop by N grades tomorrow, and don't think about cigars and whiskey.

"What about this? This is the nameplate of the ship, right? Look at this material, I feel like amber!" Hong Tao was not tired at all, and took out a board tightly wrapped by a barnacle shell, and pointed to the material leaking out of the gap, his pupils were almost square.

"It's enamel...... The back is alloy, at least in the 70s. Jim didn't even ask Hong Tao's permission, and with a wave of his hand, he threw the board back into the sea.

"This! Look at this again! Look at its shape, does it look like a front-loading cannon?" After repeated blows, Hong Tao was still not discouraged, pulled away all the garbage, and pointed to a column with a thigh-thick and more than two meters long below, full of confidence.

"Bang bang...... Dear Aite, this is an oxygen cylinder, and I can tell you exactly the date of its production, October 1987, the place of production is France! Okay, take this thing, if you encounter something that you can't see clearly, you can smash the outer wrapping layer of it, I don't think the chance of using me here is not very large, I have to have a meeting with the team, discuss tomorrow's work, and I won't bother you. Jim looked at the big creature left and right, then reached out and picked up a hammer from the tool box, and in a few clicks chiseled open the calcareous shell that was wrapped around it, revealing a dark green metal object with a steel stamp on it.

That is, I don't know much about the history of you white people, otherwise I still need you and me stinky cow X?" Hong Tao understood that people didn't want to play with him, but he couldn't force people to play with him, so he could only curse in Chinese, picked up the hammer and began to smash it one by one.

"How is it, what is the harvest today? Look at this shape, is it a pot? Could it be that you have fished up the royal soup pot of the King of Spain?" At ten o'clock in the evening, Hong Tao returned to the bar with a black plastic bag, and most of the people went back to their rooms to sleep at this time, only Levin and a few crew members were watching TV.

"Help me see, is this an American steel helmet or a German helmet? There is a bullet hole in it, what a lesson from history! A bloody lesson, don't you arms dealers know how to repent? Give me a cup of fire!" Hong Tao threw the plastic bag in his hand on the bar and asked the bartender for a glass of wine.

"Well, it's German, it's a bullet hole, but unfortunately I've never sold a steel helmet or a rifle to anyone. Tomorrow I won't go to the bottom of the sea with you, my leg hurts a little, it just so happens that the Puyol brothers play chess, and we talk about European history on the boat, and it's not bad to play chess. Levin took out a fairly complete steel helmet from the plastic bag, looked at it carefully by the light on the bar, and then carefully handed it back to Hong Tao as if he were holding a crown. At this time, he knew very well what state Hong Tao was in his heart, but if he dared to knock this steel helmet, Hong Tao would dare to let him pay a golden crown.

In the face of cynicism and sarcasm, Hong Tao stood still, firmly carried out his treasure exploration plan, and after eating at noon every day, he drove a small submarine to the bottom of the sea to claim the king, and never floated until dinner time. No matter what he did with Radha and Singh in the submarine, anyway, every time he came back, he promised not to be empty-handed, and it was all a dozen salvage warehouses full of broken copper and iron. After dinner, he went to the bilge to take a hammer and beat it became Hong Tao's daily homework, he said that smashing for an hour is equivalent to taking a walk after dinner, both exercising and breathing.

At the end of November, the Mouse Superman finally completed the scanning of more than 500 square kilometers of sea area, found out six areas that are more likely to have submarine shipwrecks, and began to carry out magnetic exploration one by one from north to south. On the first day of harvest, the magnetometer showed a strong metal signal in a piece of silt more than 50 meters underwater, and according to the strength of the signal, the object had a range of hundreds of square meters.

Such exciting news immediately made Hong Tao like a chicken, volunteered to be the operator of the submarine, and personally took Jim and Dan to dive. Since he did not have an excavation permit and could not use large-scale excavation equipment, Hong Tao had to use a manipulator to hold a portable water flow and use the strong water flow generated by it to wash away the silt in the target area little by little, and clean up the buried objects below.
