In fact, Marin's method was not something he came up with, but was learned from later generations. In the mid-19th century, slavery was abolished in Europe and the United States. Then, the plantation owners who owned the plantations and the black slaves were dumbfounded. Because, in the past, the black slaves said that they would not farm for them anymore. Or, even if you are willing to help with farming, you will fish for three days and dry your nets for two days.

Without the suppression of the leather whip, the indulgent and uninhibited nature of the old blacks was exposed. As long as they make a little money, they will disappear and go to the city to have fun, eat, drink and have fun. Then, when the money was spent, he was forced to find work again. As for the anger of the farmer? What's the matter with them? Anyway, they don't have the guts to whip those old blacks anymore.

The black hired man's act of coming and leaving when he wants, if it happens during the spring ploughing or autumn harvest, can make the farmer vomit blood in a hurry. In desperation, many plantation owners at that time learned from the experience of plantations in Southeast Asia and began to abduct honest and capable Chinese workers to help them work. It is called hiring, but in fact, when Chinese laborers arrive in the field, they will be strictly guarded, and the treatment is no different from that of slaves. However, because they signed employment contracts, they were indeed let go in the year, and the ardent opponents of the slave trade could not find an excuse to object. Of course, if you are hired into a mine, very few will come out alive after the employment expires.

It just so happens that Marin has been committed to suppressing Maozi and preventing Maozi from rising. Therefore, this immoral trick happened to be used on Maozi.

Jacob. On the same day, Fugger contacted the Venice branch with a carrier pigeon and asked them to inquire about the feasibility. As a result, the next day the carrier pigeons from the Venetian branch brought back the news that several Venetian merchants were willing to take on the business. But the requirement is that each hair is drawn into 5 gold coins......

In this way, if it is 20,000 maozi, the Fugger family will have to pay an extra 100,000 gold coins. However, for the wealthy Fugger family, it is really nothing. At this time, the Venetians had not yet fallen out with Turkey, and they and the Genoese merchants were the two major powers that had the right to pass through the Turkish Straits of Turkey. Even Marin sent a ship to transport Mao Mei, and he had to fly the Venetian flag in order to gain privileges through the Turkish Straits. But the Fugger family had no fleet, so they had to choose to be slaughtered by this sword.

Fortunately, the development of the Tyrolean silver mine is hugely profitable. Moreover, a maozi, even if you give the Venetian an extra 5 gold coins, it will only be a dozen gold coins, which is very cheap. Very strong, only more than 20 gold coins each. 20,000 Maozi slaves, which is only hundreds of thousands of gold coins. For the Fugger family, who have millions of fortunes, it is simply not worth mentioning. Not to mention anything else, just disposing of those small copper mines can allow the Fugger family to return one or two million gold coins. Spending hundreds of thousands of dollars to buy mining slaves is simply drizzle.

Seeing Jacob. Fugger made up his mind to develop the silver mines in Tyrol, and Marin suddenly put forward a condition......

"What? Do you want to take a stake in technology? Marlin-sama, this request ...... It's a bit of a strong man......"

If it's a copper mine, Jacob. Fugger didn't mind Marlin getting a piece of the pie. However, the Tyrolean silver mine is a famous large silver-rich mine in Europe, so why should the profits be distributed to Marin?

Marin smiled and explained:

"Count Jacob, listen to me first. By 'shareholding', I don't want to get a share of the silver mine, but I want to get the right of first refusal to purchase the silver produced by the silver mine. You know, there is a money shortage all over Europe right now, and whoever can get the silver will take the initiative. ”

Jacob. Fugger breathed a sigh of relief:

"I see...... I'm not going to give you too much of a discount, though. After all, this is silver, real money! The value is too high, I will give you the lowest price in the market price at most, not lower than the market price! ”

Marlin immediately agreed:

"I understand that I won't let you suffer. Moreover, I will probably only purchase silver from the precious silver mine for 30 years. Thirty years later, I'm pretty much able to control and mine that big silver mine in Japan! ”

Jacob. Fugger's heart tightened, he knew that in 30 years' time the Tyrolean silver mines would have a strong competitor. Therefore, he must explode the production capacity of the Tyrolean silver mines as much as possible within 30 years and obtain sufficient profits in advance.

You know, gold and silver are naturally money. Once mined and smelted, it can be directly used as money. For the Fugger family, which is dominated by banking, the more silver ore is mined, the more principal the bank has to lend.

In this era, the minimum interest rate for lending is 10% per annum, and high-interest loans of 20% or even 30% abound. Getting this silver, and then lending it, is the way for the Fugger family to get rich.

Jacob. Fugger and Marin agreed that Marin should not buy more than half of the silver from the Tyrolean silver mines. After all, the Fugger family was counting on lending that money.

Naturally, Marin would not object, and even, for Marin, the purchase of a large amount of silver from the Tyrolean silver mines was just a cover for him. After all, he would have sent troops to destroy the Mexican Aztec Empire in 20 years. When the time comes, he will have a large amount of gold and silver of unknown origin in his hands. If the source cannot be explained, it will certainly arouse suspicion in European countries. And the silver priority purchase contract with the Fugger family is a very good cover. By purchasing large quantities of silver from the Tyrolean silver mines, he was able to launder the gold and silver he had stolen from Mexico and even the Inca Empire......

As for the technology he intends to use to "take a stake......

"Lord Marin, what are the techniques you are talking about for silver mining and smelting that are used to 'take a stake'? Can you dramatically improve efficiency? ”

Marin nodded confidently:

"Of course, that's a must!"

The technology that Marin wanted to provide to the Fugger family was mainly blast furnaces, as well as rail minecarts, and high-manganese steel mills for grinding ore.

Minecarts are not very advanced technology, in fact, around the middle of the 16th century, rudimentary minecarts appeared in Europe. It's just that it's a rudimentary wooden track. In the 17th century, the Newcastle coal mine in England also appeared with horse-drawn rail mine cars, which became the prototype of the railway.

Marin intends to provide the Fugger family with rails with sleepers and small trolleys with dumpers directly to facilitate the transportation of ore.

As for the high manganese steel mill, there is nothing to say about this. Marin had people mix soft manganese ore with iron ore to smelt high manganese steel with excellent wear resistance. It is better to make a steel mill from high manganese steel and use it to grind the ore. At least, it is much better than the current grinding equipment, and it is also durable because of its wear resistance. After all, the abrasives of this era, which are used to grind metal ores, wear out very quickly.

……

As for the blast furnace, although the structure of Marin's blast furnace is similar, the quality is actually far inferior to that of the blast furnace of later generations. The biggest problem is that there are no blowers that are common in later generations. And if you use an ordinary bellows, it is not much more advanced than the smelting furnaces of the current era.

Therefore, in order to improve the efficiency of the air blast, Marin personally went out and "invented" the fan with the help of Leonardo da Vinci and other bigwigs. But Marin had no electricity in his hands and did not want to expose the steam engine. Therefore, he adopted a compromise method - using the high-level reservoir to impact the blades, driving the fan to rotate continuously and provide enough wind power for the blast furnace.

This necessitated the construction of a dam and the construction of a reservoir. Then, build one or more turbines under the dam. Then the water turbine, through the transmission belt, drives the fan to rotate constantly.

After testing, the wind power provided by the fan driven by the water turbine made by Marin is much more than that of the hand-pulled bellows or water exhaust bellows of this era. After all, the speed of the turbine driven by the water falling from a high place is much faster than that of an ordinary water exhaust box. The water exhaust box relies on the general flowing river water to drive the wind direction, and the speed is not at the same level as the speed of the falling water in the high-level reservoir impacting the water turbine. Moreover, the Tyrolean silver mines are located in the foothills of the Alps, and it is easy to find a small river to build a reservoir. Even, you can find ready-made waterfalls......

The faster the rotation, the stronger the wind will naturally be. The higher the wind, the higher the efficiency of the blast furnace and the faster the smelting speed. With a three-pronged approach, Marin doesn't believe it can bring a huge efficiency boost to the Tyrolean silver mines......
