The Rise of the European Emperor

Taking advantage of the opportunity of several new governors, Marin thought for a while, and planned to convene these four new governors and start a governor training class to teach them some precautions. Of course, the most important thing is to make them understand the specific responsibilities of sending them to be governors.

For example, Albert went to the twin islands of North America in order to expand inland, and the method was more gentle. Tara went to Havana, mainly to farm the land, but also to conquer those Tainos.

Gollard's task is relatively simple, he is a subcontractor, he goes to Panama to chop trees, plant grass (pyrethrum and wormwood), and build roads. In order to be able to get through the passage to the Pacific Ocean. Of course, he was at the greatest risk, and if he had yellow fever or something, he wouldn't be able to save him.

As for Wiltz, his mission is also quite special. He went to Cuba to mine. Fortunately, the laterite nickel ore is bright red and very easy to explore. If mines of other colors are found, they may not be so easy to find. Moreover, Marin remembered that in his previous life, there was a large red mine in the middle of the two lakes east of Moa. Therefore, it is also very easy for Wiltz to find laterite nickel ore. On the other hand, chromium, another ore that makes stainless steel, is a little troublesome to find. Marin knew that there was a million tons of chromite near Moa, but he didn't know exactly where. Fortunately, Wiltz is a prospecting engineer. When the time comes, let him look for iron ore near Moa, find all the iron ore nearby, and then slowly judge which one is chromite...

Anyway, the iron ore found is directly restored with a simple blast furnace. The reduction of chromite is ferrochromium alloy, also known as chrome steel, which is not easy to rust. Those that rust easily are definitely not ferrochrome. Next, the nickel extracted from laterite nickel ore is mixed into ferrochromium and refined to obtain stainless steel. Although the content of chromium and nickel is not well controlled, it is not wrong to use stainless steel. What I need is to be able to replace the copper skin to wrap the lower part of the waterline of the hull, and it is not used to manufacture any precision instruments. Therefore, the requirements for stainless steel are not so high, as long as the corrosion resistance is not worse than that of copper.

Although it is said that these four people can be trained individually, there is no need to take classes together. However, Marin believes that as a governor, one should have a wealth of experience and a good view of the overall situation. Therefore, when explaining to one of the governors, the other three can listen. Maybe they will need to use some of this knowledge in the future? After all, their current governorship is not for life. Maybe they work in this environment today, and maybe they will be in a different environment tomorrow. It's like Tara, who used to work in Twin Isles and now goes to Havana...

...

Looking at the four people sitting below listening to the lecture like elementary school students, Marin was very satisfied. If someone is not serious when learning knowledge, Marin has to consider whether it is time to change someone.

First of all, Marin wrote the sentence "No drinking of raw water" on the blackboard, and then let the four of them remember it firmly and implement it resolutely.

"But, Brother Marin, why is drinking raw water banned?" Albert asked inexplicably.

"Albert, from the moment you sit here, you are a reserve governor, no longer a child. Therefore, you must obey the rules, and at work, you should call me the Duke, not my brother. Only in private situations, you can call me brother! Understand?" Marin reprimanded sternly.

"Oh..." Albert responded aggrievedly.

"Albert, you are about to become the governor of the management side. Therefore, the first common sense I will teach you today is to distinguish between public and private. This governor training course is obviously a public occasion, not a private occasion, so, I asked you to change your title, do you understand? As a governor, the first thing you must do is to distinguish between public and private! Tell me, do you understand?"

"Understood!" Albert stood up and replied firmly and loudly.

"Very good, that's how it should be."

"Then, let me explain to you why you can't drink raw water..."

Then,

Marin and everyone explained in detail what microorganisms are, and the knowledge that some harmful microorganisms will cause people to get sick after entering the human body... Unfortunately, after the talk, the four of them all looked confused...

Obviously, they don't have an intuitive understanding of microbes. Unfortunately, Marin doesn't have a microscope right now to show them the existence of microbes.

Finally, Marlin caught fire and said loudly:

"Anyway, you only need to know that drinking raw water will make you sick. Especially in tropical areas, it is easy to get plague!"

"Plague?" All four were startled. Although they don't understand what a microorganism is, they still understand what a plague is. So, the four people who were frightened nodded one after another.

"Also, once a plague or infectious disease occurs in any place, it proves that there may be a problem with the water source there. At this time, the best way is to dig a well and drink well water. Of course, it has to be boiled and drunk."

"Then, Lord Duke, is it okay to drink cold water?" Wiltz asked weakly.

"Liang Bai Kai is also boiled water, no problem. However, the cooling time should not be too long. Otherwise, microorganisms will still invade. That is to say, the boiling water will cool down for a short time, and it will be fine to drink it. After a long time, it must be no."

The four nodded in succession, so the first principle of colony finally left a deep impression on the hearts of the four.

Then, Marin started tutoring Albert, the highest-ranking of the four, while the other three listened in:

"North America... Abu, the Indians of the Northern Wilderness Continent are divided into several branches, some of which are relatively mild, such as the Delaware, and the Wampanoag people that Tara has just contacted. However, the big Some Indians are more belligerent. Because they often hunt in the dense jungles of the northern wilderness, they have developed a fighting skill to fight against nature."

"Of course, it's not terrible to fight them openly. The most terrible thing is that those Indians hide in the dense jungle and shoot you with cold arrows. That's why I let you win over the Delaware. Because, the Delaware Familiar with the forest, not afraid of bows and arrows from other Indians."

"When the time comes, if you hire people who are proficient in archery among the Delaware and Wampanoag, and replace them with excellent bows and arrows made in Europe, you will definitely be able to suppress the indigenous bows of the Indians..."

Albert nodded again and again with a look of admiration on his face. Using Indian old jungle drivers to deal with hostile old jungle drivers, and suppressing them with special weapons and equipment, there is definitely a chance of winning.

"In addition, you have to hire friendly Indian tribes, cut down the trees desperately, and cut down the trees. Those Indian natives who are good at jungle warfare will not be worth mentioning. As long as the cavalry charges a simple charge, they will win."

"How many troops will you send me?"

"You just went now, don't think about war, first try to get a good relationship with the Delaware people, and buy Manhattan Island as a foothold. At the same time, buy oak logs aggressively. The war, it is estimated that it will wait. In addition, I have to choose strong plate infantry for you. Besides, you are the governor, and the war has nothing to do with you."

"All right……"

...

Next, Marin pointed to Wiltz:

"The place you're going has a very precious mineral called nickel... um, don't know what nickel is? No problem, I'll tell you..."

Barabara talked about nickel for a long time, and after Wiltz almost fainted, Marin stopped.

"Anyway, in the southeast of Moa, between these two lakes, there is a red soil area..." After speaking, Marin drew the approximate locations of the two lakes.

"After finding the laterite area, dig out the laterite, set up a furnace to calcine at high temperature and add air... At this time, irritating gases will escape. At that time, your entire desulfurization tower will be desulfurized with water..."

"Sir, what is the whole desulfurization tower?" Wiltz was a little stunned...

"Mad, it's nothing, you just need to know how to use it... Specifically, the exhaust gas from the calciner is passed through a pipe into the pool to avoid escape... Because, this gas, it dissolves in Water...collected to make sulfuric acid..."

"What is sulfuric acid?" Wiltz was curious.

"Your uncle, what sulfuric acid is not, you don't need to know what it is, you can collect it, you don't need to know the rest! Remember, the water should be changed frequently, otherwise the sulfur dioxide dissolved in water will be saturated..."

"Oh..." Wiltz nodded obediently without refuting.

As for how the generated sulfurous acid turns into sulfuric acid, Marin decided to let it take its course and how much it can convert. Anyway, by constantly stirring the sulfurous acid and mixing in air (oxygen), it can always convert part of it. Over time, it can slowly transform a lot.

As for how much it can be transformed in the end, it is purely up to God's will. Anyway, Marin's demand for sulfuric acid is not large. In fact, Marin knows how to convert SO2 to SO3 commercially, but that requires vanadium pentoxide or platinum as a catalyst. And neither of these two, Marin, so, had to choose natural transformation. Although the efficiency is low, it is also a helpless choice. Furthermore, because the chemical industry has not developed, the demand for sulfuric acid is not large.

...

Seeing Wiltz's vague understanding, Marin didn't expect him to understand immediately. So, he simply asked the craftsmen to make a complete set of equipment for calcination and water desulfurization tower, and let Wiltz use it directly.

After calcination, nickel sulfide is converted into nickel oxide, which can be reduced to nickel in a blast furnace...

Then, Marin told Wiltz to carefully look for iron ore near Moa. If you find iron ore, immediately use a blast furnace to smelt it out. If it doesn't rust, it's ferrochrome. Then it is melted, mixed with pure nickel, and it becomes the legendary stainless steel... It is said that there is a chromite called Mersedita near Moa, with reserves of up to one million tons, of which chromium oxide (dioxide trioxide) Chromium), up to 38.40%. As long as you find this chromite... Well, it is estimated that you have to add some iron to it, otherwise, the smelted metal will contain too much chromium...

Marin remembers that the 304 stainless steel commonly used to make stainless steel lunch boxes in later generations contains 18% chromium and 8% nickel. Because of the limited level of technology, Marin certainly cannot make 304 stainless steel accurately, but it can still be done with more chromium content, which is not a bad thing anyway. As for nickel, because it is separated from ferrochromium, it is easy to control the content. Anyway, the higher the chromium content, the stronger the corrosion resistance. What Marin wanted was corrosion resistance. At that time, if you fiddled with it, you would be able to get the iron sheet that wraps the hull. Moreover, at the industrial level of this era, the 1 million tons of chromite, it is estimated that Marin can't be used up...

After tutoring Wiltz, Marin tutored Tara and Gollard. For Tara, Marin is still very relieved. Especially in the frontier area, Tara is already very experienced. After all, Tara had already experienced the pioneering of Shuangdao. It's just that Marin told him to establish a good relationship with the local Taino patriarchs in the early stage and to establish a foothold. If those Taino patriarchs think Havana is their territory, then they can give them some glass ornaments to "buy" the land to avoid disputes.

Then, in the nearby tribes, find and support people who are close to the colonists, support them as leaders, and finally bring those tribes under their own rule. In the next step, train a group of Indian warriors who specially disguise themselves as the mortal enemies of the Tainos - the Caribs, attack and kill the chiefs of the remaining tribes, and then, as rescuers, go to take over the members of those tribes, and cooperate with those " The Caribs" pretended to fight a fight, which made them reconcile...

Listening to Marin's intrigues against the Indians, the four new governors were in a cold sweat - oh my god, I'm just here to be the governor, not to be a conspiracy to harm people... But these methods sound amazing Oh……

As for Gollard, Marin didn't say anything, just let him build a base in Cologne now. Then, plant wormwood and pyrethrum all around the base, and then rely on black slaves bought from the Portuguese to let them cut down trees, cut in the direction of the Pacific Ocean, until a road is cut. In the future, we will transport some cement over there and build a concrete road that leads directly to the Pacific Ocean to facilitate transportation... In short, Gollard's job is to be a contractor who builds roads and chops down trees... Of course, he has to pay attention to safety at ordinary times. Avoid contracting terminal illnesses such as yellow fever...
