The Treasure Hunt of an Antique Dealer

The Chinese food is plentiful and there are plenty of fresh tropical fruits, but the meal has not been finished yet, and there is new news from the "Great Shark".

Early-stage pathfinders searched this area not because they got the news of the sunken ships in shallow water, but because of the steel wreck at a depth of 50 meters: a small trawler was unlucky over there and picked it up. Corroded steel small construction.

There is a shipwreck, but the local fishermen are not interested: the water depth of nearly 50 meters is not something that ordinary fishermen can eat and salvage, even if they bring diving exhalation equipment!

For diving, a depth of 18 meters is the first hurdle, and 30 meters is the second hurdle; unless there are advanced safeguards and equipment, the absolute offline depth of 40 meters for recreational diving is the line of life and death for ordinary divers!

Besides, within the thousands of square nautical miles nearby, there were many steel battleships and cargo ships that sank during World War II. The fishermen nearby did not take it seriously.

The water was too deep, and the fishermen didn't dare and were not interested in going down. The guys who explored the way didn't give up. They inquired and searched around here, and they found five sunken ships in a short time.

When the "Big Shark" arrived, I went down and watched it with a small underwater unmanned submarine. It was initially determined that it was a cargo ship, and this made it possible for today's designated dive.

Because they have used unmanned micro-submarine to explore before, two divers this time are not wearing the kind of diving suits with compressed air bottles on their backs, but heavy duty diving suits with snorkels and communication cables connected, otherwise the news is impossible. Passed back so quickly.

At a depth of nearly 50 meters, the dive can be fast, as long as you can afford it, you can reach the seabed within two minutes without any problem.

But below, in addition to the zero-pressure rigid diving suit, no matter what kind of diving suit you wear, the working time is up to 50 minutes. This is the time that the best professional divers can reach. The average professional diver can take half an hour. Float up.

When the time is up, you must come up, and you can't go up all at once, otherwise the limbs and joints will become sore, and the limbs and joints will be sore.

The ascent to the depth of 50 meters needs to be divided into several sections, and the ascent time is about 40 to 50 minutes.

You can dive twice a day, but the dive time must be more than 6 hours away from the time of the previous water release, otherwise it is easy to get "diver's disease", and the working time on the seabed after the second dive that day must be strictly controlled , Must be less than a quarter less than the first time.

As for the first dive on the next day, the time for this dive should be more than 12 hours away from the second dive on the previous day. There is no discussion!

This is science. The iron rules engraved by countless experiments and the lives of divers must be followed if you don't want to die or become disabled!

This time the situation on the bottom of the sea was transmitted by divers through the intercom in the big helmet, and it took too long to float up: starting today, the biological clock will need to be in shifts according to diving needs, so there is no lunch or lunch time.

"The sunken ship below is about 130 to 140 meters long, with a tonnage of six to seven thousand to ten thousand tons. It should have been sunk by a torpedo.

The ship came to lie on its side when it was sinking, and it might have gone through a roll. Two large holes about 30 meters apart were exposed on the port side of the ship, reaching the cargo hold.

Divers found many black-brown surface oxidized metal ingots on the seabed near the shipwreck, and more in the cargo hold.

It is very heavy, each piece is not large, but at least more than 30 kilograms, which will be initially salvaged. "

Okay, after listening to this report, we will set off to go to the "Big Shark" side.

"What will it be?"

This is the idea of ​​a group of people: it will oxidize, then it is not gold, is it silver?

After soaking in the sea for a long time, the silver will look dark and brown and ugly.

The amount of silver transported by cargo ships will not be small, right?

It didn't take long for the yacht to get on the cargo ship, and as soon as a group of people climbed up, it happened to hit the first basket of metal ingots.

Unlike the removable mini cranes on the "Sunshine Star", the smallest crane on the cargo ship can lift tons of heavy baskets. This basket is also a big guy welded with steel bars. There are more than ten metal blocks inside. , There can be about half a ton!

Before opening the lid of the hanging basket, Zhang Nan said on the side: "It's not silver."

When a woman on the side listened to this very affirmative judgment, she looked at him with an expression of "how do you know?" Dixit asked.

Come together in Chinese and English, "I used to be a buyer of the Material Bureau, does the Material Bureau know?...

Forget it, you still don't understand.

I used to deal with all kinds of metals. These metal ingots are cast in non-ferrous metal molds, and the two ends of the rectangle are protruding from one section, which cannot be stored wrongly.

If each piece weighs about 37 kilograms, it is a tin ingot. "

Speaking forward, watching the sailor take out a piece from the inside with a little effort and put it on the deck.

He stretched out his hand, "Knife."

Without a bodyguard, the deck sailor on one side handed a diving knife with a blade length of about 15 cm.

After taking it, the thumb interviewed the lower edge, which was very sharp: Holding the handle of engineering plastic, I pushed forward along a corner of the metal ingot and cut a knife, immediately revealing a silver-white corner.

He handed the knife back to the sailor, picked up a small piece of metal cut off the deck, and looked at it.

"It can't be wrong, it is pure tin, which is estimated to have a purity of more than 90% and almost contains no lead."

In this tone, self-confidence is bursting!

Although the buyer has been a buyer for five or six years~www.wuxiaspot.com~ but the professional quality is not to be exaggerated: the purity of tin is not high, the price difference is very big, it is not that you say that pure tin is pure tin !

Confident men are very attractive, in the eyes of women. However, in the eyes of Dixit and Sawaguchi Yasushi, this tin ingot is a common industrial raw material that I have heard of, and I still feel a little pity: if it is silver, it will be a fortune!

Zhang Nan was in a good mood and asked Jamie Bostwick, the captain of the "Big Shark": "How much can there be below?"

Jamie, in his forties, smiled and said, "There are quite a few scattered on the seabed. If you explore again, there will be more than a few dozen tons of sand under the sea sand.

It’s hard to say that the cargo holds at least hundreds of thousands of tons, but it takes a lot of effort to get it all out, and it requires large-scale underwater cutting. But it's worth it, it can make a fortune! "

The sailors and divers present were in a very good mood after the boss judged that this was a pure tin ingot: For them, compared with the ancient sea-fished porcelain, the freight shipwreck transporting non-ferrous metals and strategic materials is real. Good stuff!

Now Dixit and Sawaguchi Yasuko realized that they could not underestimate the tin ingots in front of them, and the Indian beauty asked in a low voice, "It's very valuable?"

When Zhang Nan heard it, he smiled and said, "Of course it's worth it. Ten years ago, it was even more valuable. At that time, a ton was more than 18,000 U.S. dollars. Now even if it has plummeted, it can still maintain between 8,000 and 8,800 U.S. dollars per ton.

At least a few hundred tons, or even a few thousand tons, is not necessarily at least a few thousand tons. Do you think it's worth?"

As far as the cost of salvaging the seabed is concerned, this time it is really profitable: the absolute value of this money cannot be measured by Zhang Nan's worth, but should be calculated from the output ratio of the salvage company.

37 kilograms of an ingot is tin?
