The extraction of artemisinin was of great significance, because it meant that Marin could safely conquer and control the colonies in the tropics in the future.

The colonies in the tropics were of great importance, not to mention the fact that spices and sugar needed to be produced by the tropical colonies, and that canned tropical fruits could also be developed into an important commodity. In addition, Marin will also promote the cultivation of special cash crops such as tea, coffee and cocoa in the tropics. These crops all need a tropical environment, or prefer a tropical environment.

Take tea as an example, although tea is also produced in temperate regions, tea trees prefer hot and humid environments, and tea trees in tropical areas can also be grown. For example, the famous Ceylon black tea was produced in the tropical island country of Sri Lanka.

The climate in Cuba is similar to that of Sri Lanka, and tea plants can be grown and produced for tea. Moreover, tea trees have the advantage of preferring sunny slopes and do not occupy the cultivated land of the plains.

Therefore, in tropical and subtropical regions, it is completely possible to promote the cultivation of tea in hilly areas. Combined with sucrose and milk, it can form a high-value milk tea industry.

In fact, milk tea has become a very fashionable drink in Europe now. Because of the scarcity of tea, the "Earl Grey Milk Tea" "invented" by Marin has become a rarity that can only be enjoyed by the top nobles in Europe. After all, now in the European market, a tea brick can be exchanged for a war horse, which is simply black. Therefore, being able to drink Earl Grey milk tea is also a very luxurious life. If anyone entertains guests with Earl Grey milk tea, it will be more face-saving. It's a pity that the current trade in tea bricks is in the hands of the Crimeans, and if you want tea, you have to go bankrupt to buy it. If Marin can open up the route of the Ming Dynasty and obtain a large amount of tea, it will definitely be a good business.

Moreover, in addition to tea, Earl Grey milk tea also needs a lot of milk and sucrose. In this way, the promotion of milk tea, while also stimulating the sales and consumption of sucrose and milk, forming a huge industry and feeding many people.

It is said that because of the popularity of Earl Grey milk tea, the price of black and white cows in the Netherlands, which have strong milk production ability, has risen by half......

……

Speaking of which, Marin's occupation and development of Cuba is imperative!

It's just that Tara, this guy, may know how to develop, but he is really not good at expansion. This guy went to Cuba last year, and as a result, soon, he had to build the Havana Castle and take control of the large unowned forest near the Havana Castle. As for the surrounding tribes, he failed to conquer any of them......

Why? Tara's report to Marin argues that he had sent troops against a nearby tribe, but failed. It's not that they can't beat the other party, but after the other party failed, they fled directly into the jungle depths of the island of Cuba, making it impossible for Tara to pursue.

Moreover, although the militia composed of hundreds of strong men under Tara surpassed the natives in combat because of their firearms, they had no way to deal with the natives in the jungle. even, suffered a loss, losing two people. Moreover, these two men were not killed by the natives, but by the poisonous snakes in the jungle......

In desperation, Tara had no choice but to admit that she was not suitable for jungle warfare on the island of Cuba and asked Marin for support......

When she receives Tara's letter for help, Marin is furious. However, after getting angry, I have to admit that Tara has a good point......

From ancient times to the present, jungle warfare has been a difficult problem. Tropical jungle warfare, in particular, is a difficult problem within a difficult problem. Why did the cultivation of poisonous products in the Golden Triangle in later generations continue to be banned? Isn't it because jungle warfare is too difficult for Thailand and Myanmar to handle? It is said that in order to conquer Southeast Asia during World War II, Japan specially recruited a group of mountain people from the indigenous people of Taiwan for jungle warfare in Southeast Asia, and the effect was not bad......

Thinking of this, Marin suddenly remembered one thing - many of the troops under his command seemed to have been recruited from the Duchy of Württemberg, and many of them were mountain people living in the Black Forest......

These people have good stamina, are good at running, and are also very adapted to the forest environment. Although the temperate forest environment is not quite the same as the tropical forest, these mountain people of the Black Forest are certainly more adapted to jungle warfare than the soldiers of the plains.

As a result, Marin decisively recruited the generals and asked them to begin counting the number of soldiers in the army who had previously lived in the Black Forest.

As a result, a few days later, Marin received good news - about two thousand people in the army were from the Black Forest in the Duchy of Württemberg.

The most surprising thing about Marin was that more than 400 of them had worked as hunters in the Black Forest. Because of their good level of shooting and aiming, they all joined the musket team......

Some people may ask, since he is a hunter, why not be a hunter and become a soldier instead? Hunting a few deer or something can sell them for a lot of money, just like Marlin did in the first place......

In fact, this is unrealistic. Why? Because Marin originally rode into the depths of the forest to hunt. Do regular hunters have horses? No! So they can only hunt on the outskirts of the forest, and the harvest is not so big.

Moreover, this is secondary. The most important thing is that after these hunters hit their prey, how to shoot is a big problem. If you go into the city and sell it, you can easily get extorted.

In this era, the beasts in the forest are also the property of the lord, and ordinary people cannot hunt casually. If discovered, the prey taken away will be light, and in serious cases, it will be executed.

When the gate was crossed to pay the city tax, the ordinary hunters might be extorted by the soldiers guarding the gate, and even steal the prey. If you encounter a vicious lord, you may even be put to death.

Therefore, those hunters in the forest often do not dare to go to the city to sell their prey, so they can only eat at home and cannot sell it for money. In this way, those hunters are poor. Because they had no money, they couldn't afford to buy clothes, so they had to make rudimentary clothes from animal skins they had hunted. Many hunters were so poor that they went to join the army.

And Marin was different at the beginning, he was a wandering knight, a "ruthless man", and one person could fight several ordinary soldiers. Therefore, although Marin poached without a license, those ordinary soldiers defending the city did not dare to provoke. Moreover, Marin was originally a wandering hunter, hunting and shipping here today, and riding to another territory tomorrow. Even if the lords who learned that their forests had been poached learned the news, they wouldn't be able to catch up with Marin! What's more, later Marin took a group of attendants to form a group of poachers, and his combat effectiveness was very strong. If some small lords rush to chase after them, they may be killed back. Therefore, those weak little lords also turn a blind eye to shameless poachers like Marin. Unless, the other party refuses to leave in their territory, and they will drive it away.

Therefore, poachers with high weapons like Marin live well, while ordinary hunters have difficulty selling their prey, so their lives are bad. When Marin sent people to recruit mercenaries, many hunters who had a bad time simply followed Marin......

These hunters were poor, but they were familiar with the forest. Moreover, he is good at tracking and setting traps, and his vigilance is also very high. With these jungle hunters to fight those natives, it will do twice the result with half the effort.

Therefore, Marin selected more than 300 hunters from the more than 400 hunters of the former Black Forest and prepared to send them to the island of Cuba to participate in the attack and pursuit of the natives. With these hunters present, no native can escape.

In addition, Marin selected 300 soldiers who had lived in the Black Forest to provide cover for the hunters. After all, those more than 300 hunters are all musketeers, weak in melee ability, and need protection. The more than 300 assistants selected by Marin for them are all sword and shield soldiers, and their covering ability is very strong.

Those who have been eliminated by the cure are mainly people who are afraid of heat. People who are afraid of heat cannot stay in the tropical jungle for a long time. Only people who have better endurance and are not afraid of the heat can adapt to the kind of climate on the island of Cuba.

Now, Marin has a large amount of artemisinin in his hands, and with such a team adapted to the forest environment, it is very suitable to conquer the indigenous tribes of the Cuban island. Only by conquering the indigenous people of the island of Cuba was Marin able to cultivate sugar cane plantations on the island and organize the cultivation of cash crops such as tea trees......
