The Rise of the European Emperor

That night, there were bursts of "strange noises" from the tents in the military camp in Schleswig. These eager soldiers, after holding a mass wedding in the daytime, will impatiently hold their newly married daughter-in-law in their arms in the extremely soundproof military tent, and then they will begin...

For a time, "strange sounds" were everywhere in the entire camp. At night, when Marin went to inspect the military camp, he naturally felt these voices coming towards him...

Suddenly, Marin began to miss Angela and Ferris too...

The next day, Marin called Schwartz, Stade and other generals to discuss the issue of troop stationing. The Principality of Schleswig is next to Denmark, and the Danes may not be convinced. Therefore, here, a large army must be stationed in case the Danes come back. You know, the Danes also have an army of 10,000 people. Although the capital was breached, more than 10,000 people in Sweden suffered no losses.

Therefore, in order to prevent the Danes from attacking, Marin decided to leave 10,000 troops and stationed in the Principality of Schleswig, mainly in the northern region and the eastern coast, to guard against the Danish attack.

And Stade, as the commander of the 10,000 army, will sit in the city of Schleswig to guard against the Danes' counterattack. In order to allow Stade to obtain timely information, Sauert left 100 excellent scouts to inquire about the military intelligence on the Danish side, so as to leave enough responses for Stade and the 10,000 troops left behind. time.

In fact, the best commander in Marin's mind was Woolf Esbrand. However, Woolf Esbrand was born in a wild way. Although he had a lot of ideas, he had not received the education of formal military command. Therefore, Marin intends to bring Woolf Esbrand back to East Friesland for a period of time. At least, let him learn the training methods of the East Frisian army and the application of the "Marin phalanx" before he can be entrusted with the important task.

In order to ensure the safety of the soldiers, Marin decided to arrange a cement factory and a steel factory to produce a batch of cement and steel bars after returning to the Principality of Schleswig. In the north of the Principality of Schleswig, a batch of steel bars will be built Concrete fortress, used to fend off possible enemy attack.

In addition, the steel factory will also be responsible for the production of several cast iron city gates to equip several cities in the Duchy of Schleswig. After all, after the war, the artillery created by Marin blasted through the oak gate, and then buried the gunpowder barrel deep in the oak gate to blow open the oak gate. It has been spread out. If you use the oak door again, you will wait for the other party to break the door easily.

Fortunately, the steel mills in East Frisian can produce several tons of steel a day, and can build a big iron gate in two days. However, what gave Marin a headache was how to prevent the rust of the big iron gate...

You must know that Marin's current control areas are all coastal areas with humid climates. In humid climates, iron doors are prone to rust.

This era is not the afterlife, waterproof paint is easy to buy. Right now, there is no professional waterproof paint. Some paint is applied to the large iron door, although it can be waterproof in a short time. But as soon as it is washed and soaked by rain, those paints are easy to fall off. Then, the big iron gate is still easy to rust...

Right now, the most realistic technology is tinning and galvanizing. Tin plating is to make tinplate. Tinplate can prevent rust and corrosion, but tin-plated iron doors cannot be scratched. Once the tin layer is scratched, once the hole is opened, it is easy to start rusting.

Therefore, zinc plating is much more reliable than tin plating. The galvanized iron sheet is the legendary white iron sheet that is not afraid of the wind and the sun. In later generations, especially in the 1990s, when the urban management was still unremarkable, there were many tin sheds made of white iron on the streets, which were not afraid of the wind and the sun. It's just that after entering the 21st century, these tin sheds made of white iron have been demolished by the "strongest in the universe" urban management as illegal construction...

Moreover, the galvanized white iron sheet is not afraid of scratches. As long as the scratched area is not too large, the tinplate is not easy to rust. Therefore, tinplate has a wide range of applications in later generations.

And the price is not too expensive.

However, for now, pure zinc has not yet appeared in the world. Even in Huaxia, it was not until the reign of Emperor Jiajing that zinc-containing brass was used on a large scale for casting copper coins. The specific extraction of zinc ingots is about in the middle and late Ming Dynasty. Because Song Yingxing's "Tian Gong Kai Wu" in the late Ming Dynasty recorded the method of refining pure zinc.

The Europeans have been unable to master the method of refining pure zinc. This is because when the temperature of zinc reaches 906 degrees or more, it is easy to be volatilized as zinc vapor. And ordinary metal smelting reduction furnace, after adding carbon, the temperature can easily reach more than 1,000 degrees. Therefore, Europeans have not been able to obtain pure zinc. It was not discovered and confirmed as a new metal by German chemists until 1746.

The secret of this is that a condenser tube is added at the top of the reduction furnace. After the zinc vapor evaporates, it naturally transpires upwards. If a curved condenser tube is added on the top of the furnace, there is water cooling outside the tube wall. In that way, after the zinc vapor enters the condenser tube, it is easily cooled down and then adheres to the wall of the condenser tube. Then, the crude zinc on the tube wall is scraped off and further refined to obtain pure zinc.

Thinking of this, a message suddenly flashed in Marin's mind—the largest lead-zinc mine in Europe seems to be the Tara lead-zinc mine in Ireland. The Tara lead-zinc mine is located under the Tara Hills near Naveen, more than 40 kilometers northwest of Dublin, and was only discovered in 1970.

This mine, the ore reserves reached 70 million tons, and contained 10.1% zinc and 2.7% lead. That is to say, the ore produced by the Tara Mine has a total zinc metal content of 7 million tons and a lead metal content of 1.89 million tons...

7 million tons of zinc, how much tin can be made...

Unfortunately, as far as Marin knows, Dublin and the surrounding area are currently directly under the British royal family. If Marin wanted it, he had to ask Henry VII whether he would agree or not...

In line with the principle of voluntariness, Marin quickly selected 10,000 people from the remaining 19,000 troops to stay and stationed in the Principality of Schleswig. And Marin himself, with the remaining 9,000 people, a large number of livestock and baggage, and more than 10,000 people responsible for logistics, returned to East Frisland by land.

After obtaining the nominal sovereignty of Dittmarschen, Marin found out that - now the German region (excluding the Netherlands), the North Sea coast, except for the coastal area of ​​the Archbishopric of Bremen, all fell into his own. under control...

"Should I find a way to get the Archdiocese of Bremen into my hands?" Marin thought for a while, but gave up the idea for the time being.

In his view, obtaining the Bishopric of Münster is more important than obtaining the Archbishopric of Bremen. Because the southernmost part of the Bishopric of Münster is located in the Ruhr area.

According to the intelligence collected by Marin's subordinates, the Ruhr area currently mainly belongs to three forces - the Earl of Mark, the Bishop of Münster and the Free City of Dortmund and Hanseatic City.

Among them, most of the coal mines in the Ruhr area are located in the territory of the Earl of Mark, and some are located in the territory of the Bishop of Münster. Even Essen, the headquarters of the later Krupp Steel, currently belongs to the Bishopric of Münster. Moreover, there is already a coal mining industry in the area. And Dortmund Hanseatic Free City, because of its small area, only a few coal mines outside the city can be mined.

As for the land on the far west side of the Rhine, it belongs to the Duchy of Clifford. However, there are no coal mines, mainly farmland along the river. The area with coal mines is mainly concentrated in the northern part of the country of Mark, as well as the southern end of the Bishopric of Münster and near the Hanseatic Free City of Dortmund.

Just put the father-in-law Archbishop Rovere on the pope, and then help the Papal State to bring down Florence. Then, Julius II, who ascends to the Pope, can use his exploits against the Holy See as an excuse to give himself the Bishopric of Munster. Owning the Bishopric of Münster is equivalent to owning some coal mines in the Ruhr area, which is definitely a great deal...
