The Rise of the European Emperor

Chapter 1549 Technology

In fact, Marin's method was not his idea, but learned from later generations. In the mid-19th century, all countries in Europe and the United States abolished slavery one after another. Then, the plantation owner who owned the plantation and the black slaves was dumbfounded. Because, the gang of black slaves in the past refused to farm for them no matter what they said. Or, even if they are willing to help with farming, they still spend three days fishing and two days drying nets.

Without the suppression of the whip, the unruly nature of the old blacks was exposed. As long as they make a little money, they will play and disappear, go to the city to have fun, eat, drink and have fun. Then, when the money ran out, I was forced to find work again as a last resort. As for the anger of the ranchers? It's none of their business? Anyway, they didn't have the guts to beat those old blacks with leather whips anymore.

The behavior of black hired workers who come and go when they want, if it happens during spring plowing or autumn harvest, can make the farmer vomit blood anxiously. In desperation, many plantation owners at that time drew on the experience of Southeast Asian plantations and began to abduct honest and capable Chinese laborers to help them work. It's called employment, but in fact, Chinese workers will be strictly guarded when they arrive in the field, and the treatment is no different from that of slaves. However, because they signed an employment contract, they were indeed let go at the end of the year, which also left enthusiasts who opposed the slave trade with no excuse to oppose it. Of course, if they are hired into the mine, very few people can come out alive after the employment expires.

Just in time, Marin has been working hard to suppress Maozi and prevent Maozi from rising. Therefore, this wicked trick happened to be used on Maozi.

, let them help inquire about the feasibility. As a result, the pigeons from the Venice branch brought back the news the next day that several merchants in Venice were willing to take on the business. But the requirement is that each child gets 5 gold coins...

In this way, the Fugger family would have to pay an extra 100,000 gold coins for 20,000 dollars. However, for the wealthy Fugger family, it's really nothing. In this era, the Venetians have not yet fallen out with Turkey. They and the Genoese merchants are the two rare powers that have the right to pass through the Turkish Strait. Even when Marin sent a ship to transport Maomei, it had to fly the flag of Venice to gain the privilege of passing through the Turkish Strait. But the Fugger family didn't have a fleet, so they could only choose to be slaughtered.

Fortunately, the development of Tyrol's silver mines is hugely profitable. Moreover, even if you give the Venetian 5 more gold coins for a Maozi, it will only cost more than a dozen gold coins, which is extremely cheap. Very strong ones, only about 20 gold coins each. 20,000 Maozi slaves, only hundreds of thousands of gold coins. For the Fugger family, which owns millions of dollars, it is not worth mentioning. Among other things, just disposing of those small copper mines would allow the Fugger family to withdraw one or two million gold coins. Spending hundreds of thousands to buy mining slaves is nothing short of drizzle.

, Marin suddenly proposed a condition...

"What? You want to invest in technology? Master Marin, this request...is a bit difficult..."

If it is a copper mine, . However, the Tyrol silver mine is a well-known large-scale silver-rich mine in Europe, so why should it share profits with Marin?

Marin smiled and explained:

"Earl Jacob, listen to my explanation first. My so-called 'shareholding' is not to share the shares of the Runyin Mine, but to obtain the priority purchase right of the silver produced by the Silver Mine. You know, now all Europe is facing a money shortage, and whoever can get the silver will take the initiative."

:

"So that's how it is... However, I won't give you too many discounts. After all, this is silver, real gold and silver! The value is too high. I will give you the lowest price in the market price at most, and it will not be lower than the market price. price!"

Marin immediately agreed:

"I understand, I won't let you suffer. Besides, I will probably only buy silver from the precious silver mine for 30 years. After 30 years, I will almost be able to control and mine the big silver mine in Japan!"

, he knew that 30 years later the Tyrolean silver mines would have strong competitors. Therefore, he must maximize the production capacity of the Tyrol silver mine within 30 years and obtain sufficient benefits in advance.

You know, gold and silver are money by nature. Once mined and smelted,

It can be used directly as money. For the Fugger family, which is mainly engaged in the banking industry, the more silver mines are mined, the more principal the bank has, which can be used for lending.

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

——Marin purchases silver from the Tyrolean silver mine, accounting for no more than half. After all, the Fugger family was still counting on lending that money.

Naturally, Marin would not object, and even, for Marin, purchasing a large amount of silver from the Tyrolean silver mine was just his cover-up. After all, he will definitely send troops to destroy the Aztec Empire in Mexico within 20 years. At that time, he will have a large amount of gold and silver of unknown origin in his hands. If the source cannot be explained, it will definitely arouse the suspicion of European countries. And the silver priority purchase contract with the Fugger family is a very good cover. By purchasing a large amount of silver from the Tyrolean silver mines, he can take the opportunity to successfully launder the gold and silver looted from Mexico and even the Inca Empire...

As for the technology he intends to use to "take shares"...

"Master Marin, what is the silver mining and smelting technology you are talking about for 'shareholding'? Can the efficiency be greatly improved?"

Marin nodded confidently:

"Of course, that's a must!"

The technologies that Marin wants to provide to the Fugger family are mainly blast furnaces, rail mine cars, and high manganese steel mills for grinding.

Rail mine cars are not a sophisticated technology. In fact, in the middle of the 16th century, crude rail mine cars appeared in Europe. It's just that it's a simple wooden track. In the 17th century, horse-drawn rail mine cars appeared in the Newcastle coal mine in England, which became the prototype of the railway.

Marin intends to take one step at a time and directly provide the Fugger family with rails with sleepers and a small hand-pushed mine cart with a tipping bucket to facilitate the transportation of ore.

As for the high manganese steel mill, there is nothing to say about this. Marin asked people to mix pyrolusite and iron ore to smelt high-manganese steel with excellent wear resistance. It is best to use high manganese steel to make steel mills for grinding 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 abrasive tools of this era, used to grind metal ore, 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 the blast furnace of later generations. Its biggest problem is that there is no blower that is common in later generations. And if you use an ordinary bellows, it will not be much more advanced than the smelting furnaces of this era.

Therefore, in order to improve the blowing efficiency, Marin personally "invented" the fan with the help of Da Vinci and other bigwigs. But Marin had no electricity in his hand, and he didn't want to expose the steam engine. Therefore, he adopted a compromise method - using a high-level reservoir to impact the blades to drive the fan to rotate continuously for a long time to provide sufficient wind power for the blast furnace.

This requires damming the river and building a reservoir. Then, build one or several water turbines under the dam. Then the water turbine, through the transmission belt, drives the fan to rotate continuously.

After testing, the fan driven by the water turbine developed by Marin can provide much more wind power than the hand-held bellows or water exhaust bellows of this era. After all, the water falling from a high place drives the water turbine to rotate at a much faster speed than the ordinary water exhaust box. The water exhaust bellows rely on ordinary flowing river water to drive the wind direction, and the speed is not at the same level as the speed of falling water from high-level reservoirs hitting the turbine. Moreover, the Tyrol silver mine is located at the foot of the Alps, so it is easy to find a small river to build a reservoir. Even, ready-made waterfalls can be found...

The faster the speed, the stronger the wind will naturally be. The stronger 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 that it can't bring a huge efficiency improvement to the Tyrolean silver mine...
