A diving suit of hundreds of thousands of dollars is a bull fork, and after the diver wears it, he becomes a humanoid monster, and Iron Man is not so domineering!

By the way, will this Iron Man come out?

I don't know, Zhang Nan's media group acquired Marvel, but he didn't have the heart to pay attention to those "American heroes" at all, he just felt that many of the characters in it were set with a strong American stupidity!

This chivalrous and that chivalrous, and the little devil has been fighting a bunch of Ultraman monsters for decades and can never finish fighting.

But this will make the "Underwater Iron Man" in front of Zhang Nan look like a complete cargo on the ship, because the diving captain Vita Bruno is now wearing this newt 2000 full-human armored atmospheric diving suit is very heavy, and the weight in the air has reached 378 kg!

It allows divers to go deep into a maximum depth of 2,000 feet (310 meters) for a variety of operations, but in the air, the diver can only move with the help of a crane when wearing it.

It was already 7:30 a.m. on the second day of the "Searcher's" arrival in the salvage area, and the "Big Shark" had already left the sea area and returned to the United States.

Colombian Navy patrol boats all came in and circled the neighborhood yesterday evening, while the two salvage boats were communicating with each other by transport boats.

The Colombian saw that both ships were flying the Stars and Stripes, and that they were clearly on the high seas, and after a few glances from afar, they left.

They are not warships, and the Colombians can't control this stop on the high seas.

Besides, U.S.-flagged ships sail in the Caribbean, and other than the waters off Cuba don't go to find something to make themselves unhappy.

At that time, the people on both large ships did not bother to pay attention to the patrol boats of the Colombian Navy, busy with work and transporting supplies.

In order not to intersect with Colombia, the "Big Shark", which has been out for a month, only relies on refrigerated vegetables and fruits to supplement vitamins in the diet during this time.

At this point, there were Chinese cabbage, onions, carrots, burdock and even green peppers left on the ship's vegetables.

The "Searcher" is in good condition and has good facilities, and there are many refrigerated and fresh vegetables, and even a lot of perishable leafy vegetables such as spinach and lettuce, which will be quite fresh, and the "Big Shark" will be used to get some of it by boat.

As for the "Big Shark", the small number of items found in the early stage and the few divers who were in good condition and had nothing to deal with at home were transferred to the "Seeker" - continuous deep-sea diving requires enough spare manpower, and the work is very challenging for people.

Fortunately, the divers of Xingchen Company are in good condition, and besides, the boss is here, it won't take too long to stay on the ship for more than ten or twenty days.

The boss is very busy, he can't live on the salvage ship for a month or two, and when he has had enough, these few deep-sea divers who came to support and serve as reserves can return to the United States with the boss.

……

The water is too deep to anchor, and the "Big Shark", which is a modified cargo ship, has no side thrusters, and often has to play the trick of going with the flow, which is also the most important reason why it will leave: after the water depth exceeds 80 meters, it cannot carry out fixed-point salvage.

If there are currents in the sea, the anchor chain is not long enough, and the consequence of going with the tide is that you always have to start the engine to circle around the sea, and the work efficiency is very low.

In contrast, the "Seeker" has several relatively complete sets of closed-opening lateral positioning propulsion systems, although it is not as good as the "Deep Diver", when it does not anchor on the sea surface, it can automatically control the thrusters to reach the level of almost "immobility", but it will not run around with the ocean current.

If a diver on the bottom of the sea wants to ascend and the boat above floats for miles, it is not only funny, but it may even become a fatal one!

Three divers in regular diving suits have already been disembarked from the transport boat that had been lowered in advance, and the most dangerous is when the crane is hoisting Vita Bruno like water with steel cables, and they will escort the humanoid monster into the water.

Divers in regular wetsuits would then return to the transport boat and wait until a few hours later, when Vita returned to the surface with the suit's own buoyancy control, and then hung him on a steel cable and returned to the deck of the mother ship.

Seeing the diving captain being hoisted up, Zhang Nan turned around and went to the diving control room. The newt 2000 fully humanized armored atmospheric diving suit is connected to a cable and has a camera on it, which can not only communicate with the control room in real time, but also see the underwater picture in the control room.

Yasuko Sawaguchi wore a sun hat and followed Zhang Nan to the diving control room.

"Alan, is that shipwreck under the water really have a treasure from 300 years ago?"

Even if she had seen a treasure hunt for the bottom of the sea in the northern part of Jawa last time, she would still feel a little fresh.

Zhang Nan said as he walked: "If it's the San Jose, then you can't be wrong."

There are more than 280 years of legends, and there are various versions, at least some say that the treasure of the San Jose is worth 1 billion US dollars, and some say that it can reach 15 billion, anyway, it will not be less.

Not only did a group of sub-experts speculate about this, but even the writing was lively.

The Colombian writer García Márquez, winner of the Nobel Prize in Literature in 1982, published a book entitled "Love in the Time of Cholera" in '85, in which he said: 'On board the ship, a part of the treasure was loaded: three hundred chests of Peruvian silver and Veracruz silver, one hundred and ten chests of pearls collected and counted on the island of Contadora;

The San Jose also contained a treasure that was going to save the Kingdom of Spain from poverty: one hundred and ten chests of Musso and Somondoc emeralds, and thirty million gold coins. '

If it is the usual eight gold escudos, one weighs about 27.7 grams, and the smallest escudo is 3.46 grams.

If that Garcia's research, or hearsay data, is true, even if it's small, that's..."

Zhang Nan is not good at math, so his brain turned, and then he understood: "It's about 103 to 104 tons." If it's all eight escudos, more than eight hundred tons, this San Jose obviously can't fit.

However, the Spaniards minted gold coins in South America generally in a mixed ratio of models, not all 1 or 8, and the proportion of large gold coins is much smaller, about 1 to 40 top sky.

If true, at least a hundred tons ...

As he spoke, he arrived at the place, Zhang Nan sat down on a chair in the diving control room, and could see a display screen of the boss: the humanoid monster "driven" by Vita had already entered the water.

"According to the analysis of preserved Spanish gold coins, the gold content of Spanish gold coins minted in South America at the end of the 17th century and the 18th century is about 9 percent, more than 100 tons, and I don't bother to calculate the price change of the gold coin itself in the past 300 years, even if it is gold, at the very least, it should be 2 billion US dollars. ”

Speaking of this, Zhang Nan stopped, and he found a problem: the estimate of "15 billion US dollars" was calculated 20 years later, when the price of gold was about four times that of the current according to the US dollar, that is, at least 8 billion.

Add to that the other messy treasures, such as more than ten tons of silver, which may not have been swallowed up by the sea and time, and the pearls of the sea that are counted in tons, then the San Jose may really be worth tens of billions of dollars.

At this point, from the perspective of the armored wetsuit, Weta can be felt slowly diving: there is no obvious reference in the water, but the light can be felt.

From time to time, the dive instructor in the control room spoke to Vita, and the voice said, "Everything is fine in the wetsuit, it feels good." ”

At about fifty or sixty depths, a few rays of light suddenly appeared in the water, and Weta turned on the lights on the armored diving suit: the further down the light became, the dimmer it became, and once it reached a depth of 200 meters, it was basically pitch black!

The diving suit worn by the dive leader has its own power supply, and the lights are battery-powered. The connected cable does not supply power to the wetsuit, but only transmits communication signals.

The dive was fast and then slow, and it took about five minutes before the display showed a silt bottom that looked grayish and white under the light.

There were a few strange-looking fish swimming by on the bottom of the sea, and Zhang Nan also saw crabs crawling with no names.

The sunlight that can still reach this depth is almost negligible, and the pressure of more than 20 atmospheres is not a joke, but there is no shortage of life here.

In fact, not to mention the water depth of more than 200 meters, there are complex life in the Mariana Trench at a depth of tens of thousands of meters, but it is basically unknown.

Last night, the Searcher released an unmanned small submarine to explore the bottom of the ocean below, and the location where Weta arrived was on top of the remains of the wreck, very accurate.

Imprecision is impossible: a metal object protruding thirty or forty centimeters on the seabed is a Spanish cannon of the late 17th and early 18th centuries!

Vita didn't even need to turn on a few thrusters to move his position, relying on buoyancy, it took a little effort to stretch his legs to remove the silt from the bottom of the sea.

When the stirred up silt dispersed, through the display screen in the diving command room, Zhang Nan saw something on the bottom of the sea: a small black disc.

These are obviously metallic, and judging by the color, these are silver coins!

This will make Weta perform a seemingly difficult maneuver underwater: he kneels with his right leg in turn, and the knee joint of his armored wetsuit allows him to do this.

I had to make such an awkward shape, otherwise the two large multi-functional pincers on the two anthropomorphic, super thick arms of the wetsuit would not reach the seabed.

Weta controlled the movements of the big pincers in the "aluminum alloy super thick arm", and Zhang Nan, who was watching the screen on the ship, sent him a command through the headset: "Weta, turn over those coins." ”

"Yes, boss. ”

Vita's voice was clear and crunchy.

The large pliers are very flexible, not to mention flipping coins underwater, and even clamping coins is no problem.

But here's the problem: it's not that there are astronomical coins, just this coin that Weta kicked out, and he couldn't finish painting it for hours just by manipulating the metal tongs to clean it.

Zhang Nan looked at the situation and said to the others in the diving command room: "It's too time-consuming, it seems that you have to put a shovel on one of the arms of the diving suit." ”

Everyone had no objections, and Vita, who heard the voice, went down to the bottom of the sea and said, "Boss, next time you dive, you have to get the shock pump down and blow this silt away." ”

Shallow sea salvage can be dredged with an air pump, but not in the deep sea: how can the air be pressed?

Then you have to use cables to electrify and put a flow pump on the bottom of the sea to deal with the silt.

Do not spray high-pressure air, and temporarily use the accelerated water flow to impact the sludge. This device "Seeker" is on it, and it is also expensive!

Just a water pump, it is cheap to use on the road, but once it is paired with the word "deep sea", the treatment of cod liver oil is not particularly expensive, and the others are not cheap.

A piece of metal was turned up, and Zhang Nan saw it clearly, "It seems that they are all silver coins of the Eight Mile Cross." ”

said to Guan Xingquan, who was watching the excitement on the side: "In Huaxia, the old man calls it 'Benyang'." ”

He will have two in his pocket, which were salvaged by the "Big Shark" before.

Spanish Barilee silver coin with the Spanish coat of arms on the obverse and the royal coat of arms on the reverse.

There are also Latin letters and Arabic numerals on the edge of the coin, and the pattern of the coin is divided into four small patterns on the obverse and reverse of the coin, separated by a cross, and the four small patterns can be combined into a large pattern.

The obverse depicts "Two Lions and Two Cities", with two castles facing each other in the upper left and lower right, and two standing lions facing each other in the upper right and lower left: this is the national emblem of Spain, and the standing lion and the castle represent the ruling king.

The cross represents the cross, indicating that the Anglican religion of Spain is Christian, and because of the cross on the silver coin, this type of money is also called a cross coin.

On the obverse of the coin is the inscription: Hispania RVM, which means King of Spain and Holy Roman Emperor.

As for why it is called eight liels, because of the Spanish numismatic octal system, 8 rils are equal to one Spanish dollar, or "a piece of silver": one dollar is the standard, and 8 lils are divided into 4 liels, 2 liels, and 1 lil.

As for the name of this "Benyang", it is unique to China, and it can be confirmed that the earliest Spanish silver dollar that flowed into China should be COB Benyang.

COB, which is a Western transliteration, is generally called cobmoney in Europe and the United States, abbreviated as cob, which is "Kaber".

Benyang is actually a type of minted coin, which is supposed to be a silver bullion, irregularly shaped, but with appropriate weight and fineness, and has been minted since the reign of Philip II in Spain in the mid-to-late 16th century.

This type of "kabo" can also be divided into two categories, one is the cross on the back of the Spanish coat of arms on the front, and the other is the cross on the back of the double column.

The "caber" was minted in Central and South America until 1732, when a new type of double-column silver coins began to be machine-minted at the mint in Mexico.

Because the "Kabo" is a silver coin, although the fineness and weight have a certain return, but in the actual minting process, the situation of stealing color and reducing weight also occurs from time to time, which is similar to the silver in China.

Zhang Nan had Benyang in his previous life, and he also knew that this "Kabo" had been circulating according to the method of silver bar weighing for nearly 200 years from Huaxia to China, and did not play a role in counting silver coins.

The new double-column silver coin is different, because it is machine-minted, the fineness is standard, the pattern is exquisite, and it is easy to carry, and it can be denominated by the piece.

As a result, these double-column Spanish silver coins replaced silver taels as the accounting standard in coastal areas during the Qianlong period of China!
