In fact, even if François I knew about this, he would not take it too seriously. At most, he would be unhappy. Why? In history, the German princes chose him to fight against the powerful Charles V and prevent the Habsburg family from being too strong.

But now, because of Marin's intervention, Prince Juan of Spain was not dead and Charlie failed to inherit the Spanish throne. The German princes naturally would not worry that the Habsburg family was too strong, nor would they have the idea of ​​pulling the French king and Charlie into battle.

Of course, when the Habsburgs conquered the entire Switzerland, the princes would still feel pressured. However, there was no pressure from Charles V, who had united Spain.

In other words, Marin's disruption this time was just a break of François I's extravagant hope, not something he could get. The two sides would definitely have a rift at that time, but they would not be able to fight.

However, Anthony, Duke of Lorraine, who was exposed by Marin, completely hated Marin. After all, Marin was very disrespectful this time. Originally, Anthony, who also served as Duke of Lorraine and Duke of Barr in France, was very generous in both Germany and France, and everyone was very proud of his face. Unlike Marin, this time, he made him unable to come to Taiwan on the spot. What the aristocrats wanted was face, and sometimes they had to give way to face. Therefore, Duke Anthony and Marin had formed a bond. If there was a chance to stab him, the other party would never be vague. Even if Marin agreed to purchase more iron ore of Lorraine, it did not reduce Duke Anthony's hatred of Marin.

Why did Marin buy Lorraine's inferior iron ore? This involves the problem of weapons and equipment. Lorraine's iron ore has low grade and high phosphorus content. This kind of steel smelted by iron ore is OK to make agricultural tools and simple tools, but it is very fatal to use it to make weapons and armor.

High phosphorus content will make the steel highly brittle and easily break when it collides with enemy weapons and armor. It will be more fatal when used on firearms and will cause explosions.

Even if Marin uses quicklime as a slag-making agent, it has a certain desulfurization and dephosphorization effect, which is good for desulfurization, and the dephosphorization effect is not very good. Dephosphorization mainly relies on oxidation reactions to produce P2O5 discharge. However, dephosphorization is best at low temperatures. How high is the temperature of the steelmaking furnace? Not only is it not conducive to dephosphorization, it may also reversely regenerate phosphorus-containing impurities, reducing the dephosphorization effect.

In later generations, oxygen top blowing was mainly used to increase oxygen supply, so that oxygen and phosphorus could generate P2O5 (360 degrees sublimated into gas). This method has a strong ability to remove phosphorus. But in this era, it was difficult to blow the oxygen top, not to mention oxygen top blowing, air top blowing.

Therefore, even if quicklime is used to remove phosphorus, the steel produced by Lorraine iron ore with high phosphorus content is still of poor quality and cannot be used to cast guns and manufacture gun barrels. It is not that it cannot be manufactured, but that it is just that the quality is poor.

Why did the French fail to defeat the British in the naval battles in later generations? In addition to the British having the technology of refining steel for reflex furnaces to cast guns, the Lorraine iron ore used by the French themselves was also an important factor in the French's always suffering.

The same is the bombardment of naval guns. The French used steel cast guns smelted by Lorraine iron ore to frequently explode. How can they compare with British naval guns?

In fact, German Gothic plate armor and Italian Milan plate armor are unwilling to use steel produced by Lorraine iron ore. It has nothing to do with it, it affects the quality.

What does Marin want to do for Lorraine iron ore? Build agricultural tools! The steel smelted by Lorraine iron ore is not good for use as weapons and armor, but it is no problem to build agricultural tools. For example, hoes deal with soil, not things that are both steel. Therefore, high phosphorus content is not a problem. Of course, it is not good to use as a mineral pickaxe, which is easy to collapse. After all, high phosphorus content is cold and brittle. But the mineral pickaxe is not considered a agricultural tool...

On the one hand, Malin wanted to sell agricultural tools to these unfriendly princes. After all, the blast furnace iron smelting in Beihai Kingdom is relatively low, so it is still a coke.

However, Malin was worried that these hostile princes would buy the iron farm tools made in Beihai and melt them into weapons and armor to attack the Beihai Kingdom. Therefore, Malin had been reluctant to sell iron tools to the various princes before.

But the iron tools produced with Lorraine iron ore are different. Even if this inferior steel product is melted, the quality is still not good. There is no problem in making agricultural tools and daily tools. If you create weapons, armor and even guns and cannons, there will definitely be problems.

While selling iron farm tools to make money, you don’t have to worry about hostile forces using weapons and armor to deal with yourself. Why not do it?

If we travel to ancient China, Malin would find a way to trade with the grassland tribes and deliberately trade with the grassland people with high phosphorus content. In this way, if the other party uses it to build a sword, it would be unlucky, and it would be easy to break down when chopping...

What? You said that iron ore with high phosphorus content like Lorraine iron ore is difficult to find? Don’t you know that the high phosphorus content in bones? Especially fish bones. When smelting iron, add some fish bone meal and the smelted iron content will increase. At that time, there is no problem in building an iron pot, and it is easy to break if it is made by creating a scimitar...

Ashes are a magical thing. This thing is added to porcelain clay and the ceramics burned are the best bone porcelain. However, when added to iron ore, smelted, they are inferior brittle iron.

Of course, the phosphorus content should not be too high. If the phosphorus content is too high, there will be problems in building agricultural tools, which will lead to easy breakage of agricultural tools. Therefore, Marin also needs to ask his craftsmen to test steel with multiple phosphorus contents and choose steel that is just suitable for making agricultural tools but not suitable for making guns and cannons.

If it is too obvious, even the agricultural tools are made, then no princes will use them to melt the weapons and armor. Therefore, there are more attempts to do this proportion...

In order to make the princes willing to buy the iron farm tools of Beihai Kingdom, Marin brags with confidence, that is, using our new iron farm tools, the Beihai Kingdom has only had a bumper harvest every year...

As for the real high-yield secret fertilizer of the North Sea Kingdom, Marin didn't mention it at all, and asked it was Italian volcanic ash. There is a species, you go to compete with France and Spain for the Kingdom of Naples...

Under the obviously misleading propaganda of Marin, many princes became interested in the iron farm tools of the Beihai Kingdom.

Moreover, Malin is not just a scam. In order to enhance his persuasion, Malin even took out the curved plow, which amazed the princes. However, Malin did not take out the most advanced magical artifacts such as Prade Pear Cart and Mali. He was here to make money, not to lead the princes to get rich together. Therefore, giving a little bit of good things is enough. It would be too stupid to take out all the good things.

In fact, the Quyuan Plough is a magical tool for self-cultivated farmers, and for the nobles, it is just that.

Why? Because the biggest feature of the curved plow is to save animal power. The straight plow that originally required two cows to pull becomes a curved plow, and one cow can pull it.

This is of great significance to ordinary self-cultivated farmers and can save animal power. But for the great nobles, animal power is not a problem at all. Some of them are cattle and horses. In this era, self-cultivated farmers did not have to pay taxes. Therefore, even if Marin sold the bell plows to various countries, it would not bring huge changes to the nobles' farms. At most, it saved the number of animals used, but the labor efficiency still did not improve much and had no significant impact on output.

Of course, this does not affect the princes present's surprise after hearing Malin's introduction. After all, this thing sounds tall and above. Moreover, it is said that it comes from the legendary Eastern Empire, which seems even more mysterious...

Moreover, the so-called "Prad plow truck" in the Beihai Kingdom is actually transformed by combining the curved plow and the Saxon heavy plow. The Saxon heavy plow is also called the Saxon wheel plow, which has a wheel that controls the depth of the plow land and the direction of the plow. However, the plow bar of the Saxon heavy plow is straight, while the curved plow is curved. The Prad plow truck replaces the straight plow bar with a curved plow, allowing the three curved plows to be arranged side by side on the wheel plow to form a plow car with higher tillage effect, and that's all.
