In fact, Redondo as the Duke of Coimbra, Jorge. Morality. The important business representatives of Rencastel have a lot of authority on this issue, and can even make decisions on this cooperation.

However, Redondo came this time to get porcelain and silk for the in-house price. Therefore, he deliberately made the issue very complicated. Then, as expected, he asked to buy another batch of porcelain and silk. Moreover, this thing is very righteous and awe-inspiring on the surface, as if it will not let Marin suffer. However, now that Marin has a request for them, how can he not suffer?

In the end, Marin could only pinch his nose and take Redondo to the warehouse, where he selected dozens of fine porcelain and a batch of fine silk. As for the price, it must be a very good price......

Of course, Marin will not suffer either. Even if he was given a preferential price, he still had a huge profit. For example, porcelain, although it does not have more than 60 times the windfall profit at the Lisbon auction, but after a 5% discount, there is still a 20 or 30 times windfall profit.

As for silk, it was not so profitable. This is because porcelain cannot be produced in Europe, but silk is still available. For example, Florence in Italy and Lyon in France are both important silk spinning centers in Europe. Although the quality of European silk is somewhat inferior, it still solves the problem of having and not having it. Therefore, silk cannot be sold for a sky-high price. But because of its good quality and fame, it is still several times more expensive than local European silk.

……

Redondo took advantage of it, and naturally went back satisfied. But Marin did not lose either, in addition to the low cost of porcelain and silk, he was also very advantageous in this trade cooperation.

According to the initial intention reached with Redondo, once the cooperation is confirmed, Redondo will establish a trading company in Portugal specializing in the trade of rhino horn and skins in the West African grasslands. The business area was in the area of Senegal and southern Mauritania in later years. Of course, you have to have the ability to go deep into the hinterland......

Once this permission is obtained, Marin will form a team and travel to the Senegal region to work on the acquisition of rhino skins and horns. Of course, they also have a very important job of instructing the local black uncle to hunt rhinos......

The Black Uncles are not very intelligent, and are somewhat helpless against the rhinoceros with too thick skin and very ferocious. Therefore, Marin's team will instruct local blacks to use traps to kill rhinos.

At the same time, Marin would also have the forge make a batch of extremely sharp high-carbon steel short knives to give to the local black leaders. The function of the short knife is to allow the black uncles to cut the thick rhinoceros skin after killing the rhinoceros. In order to prevent the rhinoceros skin from being too difficult to cut, this special short knife will also have serrated teeth. If you can't cut it, you can still use a saw......

It may not be the best to make a long saber from high-carbon steel, because the toughness is not enough. However, in the case of short knives, toughness is not so important because of the short blade. In addition, the short knife will not collide with other weapons......

As long as the local blacks were taught how to hunt rhinos and given them short knives to cut rhino skins, Marin would have been able to buy enough and cheap rhino skins. Because, those black uncles are really easy to deceive......

As for the number of rhinos, according to Sir Redondo, who was in charge of trade in West Africa, rhinos were everywhere in the savannah of West Africa in this era. In the grasslands off the coast of Senegal alone, there are no less than a few thousand black rhinos. If you go deep inland, it is estimated that it will be more. Anyway, it's all over the grassland......

In fact, these rhinos are also a scourge to local blacks. Why? If there are rhinos, it will affect their agricultural activities!

As a frontier region of the Mali Empire, Senegal actually has a relatively primitive agriculture. The local people also rely on large rivers such as the Senegal and Gambia rivers to cultivate sorghum, rice and cotton. Moreover, there is cattle breeding and a more extensive fishing industry.

However, large and ferocious animals such as rhinos and elephants have become the biggest hazard to local agriculture. They are even more harmful to agriculture than carnivores.

You know, those carnivores will definitely not go to the scourge of crops. At most, trample on the crops as you pass by. However, elephants are different from rhinoceros, they are herbivores! And crops, unfortunately, are also one of the herbaceous plants......

As long as elephants and rhinos pass through the crop fields, their huge bodies can not only trample on many crops, but also often eat large quantities of crops.

On the contrary, most of these crops were planted on the Yamato side for easy irrigation. Elephants and rhinos also like to go to the river to drink...... Therefore, there are naturally many crops that have been plagued by elephants and rhinos......

And the local blacks, lacking the weapons to deal with rhinos and elephants, often have to watch them scourge the crops and dare not stop them. Otherwise, if you anger these uncles, you will be killed......

……

How to say, with the existence of these herbivorous giants, the locals don't want to farm well. Even if you build a fence, in front of the elephants and rhinoceros, the fence or something, if you arch it slightly, it will disappear immediately...... Then, the crops should be stepped on, and the food should be eaten......

Dealing with these formidable herds of elephants and rhinos often requires the use of armies armed with metal weapons. But Senegal is a remote area of the Mali Empire, so naturally there is no army and no metal weapons. Faced with the ravages of elephants and rhinos, local farmers have no choice but to ......

In fact, the extinction of the black rhinoceros in West Africa in later generations was inseparable from the driving and killing of local farmers. If you want to farm well, these grandfathers must die, or they must be driven away.

And after driving out these tyrannical masters, agriculture in West Africa has indeed developed to a certain extent. At least, not as lacking food as in East Africa.

On the other hand, East Africa is the case. Wildlife in East Africa is very well preserved. In order to protect the animals in the East African savannah, the brain-dead leaders of East Africa have followed the advice of Western countries and established a large number of nature reserves to protect wild animals such as wildebeests, zebras, antelopes, and bison......

And with these herbivores roaming the savannah, the local people don't want to farm. Why? You just grow food, and once you encounter a herd of wildebeests or antelopes that pass by your house, you can also eat up your crops. The herd passes, and the crop does not leave a piece of armor......

Then, the East African country was very short of food, starved to death every year, and the children were as thin as skeletons......

But these fools never thought that as long as they hunted a large herd of migratory wildebeests, they could make a lot of jerky and feed a lot of people who were dying of starvation.

Then, without the herbivorous fauna, the local food can be grown. Even if the land is not fertile, grow potatoes and corn in a nutshell, right?

But those black uncle officials have different brain circuits than people, they would rather starve a large number of citizens to death, but also protect those wildebeests, antelopes, and zebras...... It seems that those animals are their citizens, and their citizens are inconsequential animals......

……

Anyway, Marin felt that he was sending people to help the locals hunt rhinos in the West African savannah, for the sake of the locals. This is a win-win situation, for the sake of the survival and development of local people. As for the brutes, can they compare with people? So, it is righteous to hunt rhinos. Don't believe it, you see that agriculture has developed in China, and rhinos and South China tigers are almost extinct...... If rhinos and South China tigers are still everywhere, can everyone still farm well?
