Previously, when counterfeiting French silver coins, Marin deliberately had his men make the mold very rough. In addition, when the coins were pressed, the spiral press did not exert all its strength, resulting in the pressed French "silver coins" being rough and looking like they were made by hand.

But for the production of brass coins for his own country, Marin did not have to deliberately make the molds rough, but ordered the craftsmen to be sure to strive for fine precision. In this way, it is difficult for others to imitate it. Carving a delicate pattern on a copper coin weighing only 1.5 grams is tantamount to dancing on the palm of your hand, which is very difficult. As a result, those traditional handmade coins are often of varying quality. After all, people make mistakes. The machine will not, as long as the mold is not damaged, the copper coin pressed out is the same. Moreover, the convex font can be pressed deeper, just like the steel seal of later generations.

Don't look at copper as hard, but if it is in a high temperature state, copper becomes very soft. As long as you get an annealing furnace and heat the cut round copper sheet to more than 700 degrees, the copper sheet will be very soft. At this time, put the copper sheet into the coin press with a clip, turn the spiral column and press it quickly, whatever pattern you want. Moreover, the patterns are beautiful and precise, and the traces are very deep.

You can't do that if you're handcrafting. Why? Because it's slow to build by hand. The copper sheet is taken out of the annealing furnace and the temperature drops below 700 degrees after a few knocks. Then, the originally softened copper slowly hardens, making it very difficult to process. And machine pressing is different. Since it can be pressed in a short time, it is guaranteed that the machining will be completed before the copper sheet softens.

Sure enough, the copper coin of the Nine Crosses Golden Eagle processed by the mint was of very good quality. The patterns and words are not only exquisite and precise, but also have the depth of the patterns and words almost as much as gold coins. However, if the purity of the gold coin is high enough, it is very soft, and the craftsmen can naturally hammer it by hand to a certain depth. However, today's impure silver and copper coins are often difficult to achieve by hand because of their high hardness.

In addition, it is a copper coin made of brass, which is shiny gold, causing many people to almost mistake it for a gold coin. Fortunately, gold coins are generally 3.56 grams, which is much larger than these small 1.5 gram copper coins. Otherwise, it's easy to be misunderstood.

After making a batch of small copper coins, the mint suddenly declared that brass was in an emergency. It turned out that the metallurgical plant had a limited reserve of copper ore and more copper ingots. However, it is difficult to use copper ingots directly for smelting brass. In desperation, Marin ordered a large amount of copper concentrate powder from the Fayilun Copper Mine, which had recovered half of its shares, for the smelting of brass. The first batch of tens of thousands of small brass coins was sent by Marin to Kohler to Emden, the core trading port of the North Sea Kingdom. As for the first object of use, it is, of course, a tavern. After all, a single silver finney coin can buy a lot of loose beer. Swap it for 8 copper coins for wine, and the amount is more modest...... Then, the large-scale promotion of copper coins can only wait until brass can be produced in large quantities......

……

When Marin made brass coins, it was in the spring of March. This season happens to be a very busy season for spring ploughing. In addition to Manhattan Island, which specializes in winter wheat, and the tropical colonies that do not need to think about the season, the mainland of the North Sea country, and the colonies in North America, they are busy with spring ploughing at this time.

Unlike sheep, which kills males and keeps females, cattle are service animals, and bulls are the main force of servitude, even if they are castrated bulls.

Therefore, the bulls of the North Sea Country, except for a small number of strong bulls without horns, survived because they had to keep their seeds. The other bulls were stabbed in the crotch...... Then, a copper ring was put on the nose......

Next, it's time to train the bulls. If it's obedience, it's fine, but if it's disobedience...... It can only be made into beef......

As for the cow, although it can't catch up with the bull, it can work, but it is only a little stronger, but it is better than no livestock. The most important thing is that a cow can give birth to calves......

Moreover, unlike in previous years, the fields of the North Sea Country, mainly in the old provinces of East Friesland, have once again appeared for arable land......

In the past, because he had always advocated cattle farming and the source of cattle was abundant, Marin did not look down on those horses with high breeding costs. Therefore, the first thousands of horses from the East Friesian Lamber Kingdom were either used to pull carts, or they were sent to the North American twin islands to be used to breed and give birth to mules with donkeys.

Marin even plans to introduce cattle farming instead of horse farming in other North Sea countries outside East Friesland to further save on feeding costs.

But Mikel's words woke up Marin - although the cost of raising horses is expensive, there is a lot of arable land. For Marin, who lacks a population, the use of horse farming is the most reasonable, and the cost of breeding should not be considered......

Then, Marin's attitude changed dramatically, and he made a great adjustment in this year's spring ploughing - estates with enough labor force continued to use oxen for ploughing, and allocated more to ploughing cattle; On the other hand, the manor estates, where there is a slight shortage of labor, mainly use horse farming......

In addition, Marin used tough and semi-hard-line means to replace all the estates of the former nobles and Junker landlords who were not his own people to the province of Bremen. Even the fiefs of the former nobles of the Earl of Oldenburg and the Duchy of Schleswig, which had been on the sidelines before, were transferred to the province of Bremen. In this way, the province of Bremen became a concentration of abandoned people.

However, unlike the exile of other countries, these abandoned nobles did not suffer at all after their fiefs were transferred to the province of Bremen. Because, the land of Bremen is also quite fertile, no less than the land before them. The only bad thing is that Marlin won't be open to them for new farming technology. In this way, the output will not go up. However, for the curved plow, Marin still shared it with them. After all, the curved plough only saves animal power and improves the efficiency of cultivated land, and has little impact on crop yields.

But this also stunned the nobles who stood aside. They even thought it was Marin's agricultural secrets. However, no one dares to leak secrets casually. After all, Marin's ruthlessness is not for fun. Influenced by the ancient Chinese culture, Marin killed the nobles like to "cut off all the doors", and the nobles committed a crime alone, and the whole family died. Therefore, these living nobles have long been killed and afraid, how dare they betray Marin casually?

Moreover, Marin is equivalent to giving up the province of Bremen, and those nobles are tossing around in the province of Bremen. Even, the nobles who were originally restricted in freedom and concentrated in Las Vegas City, Marin allowed them to return to their estates. Of course, it was a manor house in the province of Bremen.

However, many aristocrats have adapted to the luxurious life of Las Vegas and are no longer willing to return to the country estate. In this regard, Marin's attitude is - casually, as long as you don't recruit troops to rebel, or commit crimes and killings, you can do anything else...... In addition, if you want a woman, tell Las Vegas that you have paid a deposit in advance, and you can help bring a few beautiful hairy girls over......

That is, Marin has already decided to abandon the province of Bremen as a region for the old aristocracy in captivity. Of course, there are areas in Bremen that are not part of the old aristocratic estates, and Marin does not care. However, the new agricultural techniques were not easily promoted there, lest the old aristocracy find out about it. However, the plough and the plough oxen, Marin still provided them in abundance. After all, there really is no shortage of cattle right now. The Crimean Khanate now supplies tens of thousands of cattle every year, and Marin has cattle in his hands.

Even, because of Marin's actions, the Crimean Khanate reduced the number of robberies. Why? If there is a chance to make money peacefully, who wants to go out and work hard? Now, Crimea has expanded the scale of cattle breeding. The reason why they always went out to rob people in the past was because other countries were more resistant to the Tatars and were unwilling to trade with them. And the Turks, who were willing to trade with the Crimean Tatars, did not have a shortage of cattle and sheep at all, and only needed women and children looted by the Crimean Khanate...... Then, because of the demand of the market, the Crimeans had to rob the population of the countries of Eastern Europe......

How to put it, market demand determines everything. The Crimean Khanate was a country that saw money, and the market demanded slaves, so they went to Eastern European countries to grab people. When the market demanded cattle, they turned into herders and went to herd cattle.

Of course, the demand for Mao Mei and Mao Zi (Mao Zi's child, referred to as Mao Xiao) in Turkey is also very stable. So, now the Crimean Khanate is grazing cattle and grabbing hairy girls and hairy children. Of course, there is also Grandpa Mao. It is said that Grandpa Mao is also quite popular in the market now. After all, Grandpa Mao is strong and able to work, and he doesn't have to worry about being green, and Turkish beards can also use it with confidence...... Even some wealthy Turkish families from ordinary families like to buy Mao's father-in-law as a slave and help herd sheep......

Then, under the bewitchment of the Crimean side, coupled with the fact that the Beihai country did lack a population, he wanted to buy Mao Mei and Mao Xiao in large quantities. As for Grandpa Mao, it seems that you can also buy a little......

Mao Mei is beautiful and strong, and she can be a wife for the young people of Beihai Country. At the same time, it was also possible to be a woman for the colonists, and giving birth to children was the growing population of the North Sea Country. Usually, the strong hairy girl can still help with the work. As for the furry children, Marin only needs to be under 8 years old. Because, such a small child can be raised and become a real citizen of Beihai Country. If it's too big a teenager, then it won't be able to raise a mature one.

As for Father-in-law Mao, Marin didn't dare to buy more. Why? Because these father-in-law Mao were forcibly castrated as adults, they must have a lot of resentment in their hearts, and they have their own mature values, which is difficult to return. If you buy too much and let them get together, you may take revenge on the society......

It's just that Marin suddenly thought of a good place to settle Mao's father-in-law - the Senegalese grassland......

Marin really couldn't trust the Black Uncles to hunt rhinos, after all, these Black Uncles were not smart enough to ride horses. Even if Marin sent a team to teach them, they might not be able to learn it. And those Mao Gonggongs are different, they come from the Eastern European steppes and near the steppes. It was convenient to send them to the Senegalese steppes to hunt rhinos. After all, many of these hairy fathers can ride horses and use modern equipment. Even if you can't, it's fast to teach.

Unlike the local black natives, if they are given muskets, they may not be able to hit. For example, how poor is the combat effectiveness of the armies of those black countries in Africa in later generations? They use firearms, which are largely unaiming. The AK47 is used on a large scale because the AK can blind the enemy. As for precision aiming shooting? Sorry, but if you look at the AK-wielding shooting posture of the African black guys, you can see if they can shoot accurately - the regular army in other places is holding guns in both hands, stooping forward, and using cover from time to time. And the black uncles, standing right there, lifted AK above their heads in ecstasy, completely wasted...... Often, after a battle of mutual fire, a lot of bullets are knocked out, but there are not a few people killed, and the sound of AKs is heard......

Therefore, although Marin has come up with a steel ball bullet specifically to deal with rhinos, he still has to have a reliable shooter to use it. If you use a musket with low accuracy for local black buddies, it is estimated that the shooting accuracy is comparable to that of the national football team. And Grandpa Mao's shooting talent is better than that of black buddies......

It's just that Marin didn't know that it was this batch of Mao Gonggong he sent who taught the locals to ride horses and shoot. Then, the indigenous people of Senegal grew into one of the most formidable forces in West Africa. Even, in the myths and legends of later generations, this group of Mao Gonggong became the "divine envoys" sent by the gods to guide the black buddies in Senegal. It's just a pity that those gods can't look down on the black girls in Senegal, otherwise, it's better to keep a "god seed"...... (Mao's father-in-law cried and fainted in the toilet - paralyzed labor and management were cut JJ, how to keep seeds...... ）
