After Christmas, Columbus returned to debrief. In fact, Columbus's debriefing was not too important. Because, Marin will not use this route often in the future.

However, this route is still needed. Mainly, Marin wants to use this route as a cover, covering the Pacific route.

Therefore, in the future, Marin will still send one or two ships every year to pretend to take this old route. But the main force, in fact, is taking the Pacific route.

Why cover the Pacific route? The reason is simple - if Marin's fleet only took the Pacific route, then European navigators and adventurers would have been curious about this route.

Once they are curious, they will secretly go in search of the Pacific route. Then, inevitably, there will be a voyage along South America. If they discover the richness of South America, with Marin's current control ability, they will not be able to keep South America at all. After all, South America is too far away, and Marin's fleet has not yet exploded.

Therefore, Marin needed an eastern route, covering the Pacific route. As soon as the Eastern Route opens, it will inevitably attract the attention of the whole of Europe. When the time comes, those daring navigators and adventurers will be focused on the routes along the coast of Africa, and they will have no time to look westward. Of course, these secrets cannot be kept forever. When the eastern route is overrun, there will always be navigators who set their sights on the western hemisphere. However, by the time they discovered the problems in the Western Hemisphere, Marin would be able to explode the superfleet. When the time comes, whoever disobeys will be beaten. It's just that the process takes decades at least. Therefore, Marin must keep a low profile during this time. If you want to be in the limelight, let Portugal go out......

Moreover, Marin saw a lot of intrigues and tricks, and also pointed out an underworld path for the Portuguese - to occupy Malacca and tear his face with Daming......

In this way, Portugal will inevitably not be able to develop normal trade with the Ming Dynasty. However, the Portuguese are not stupid. When they have a problem, they will find a way to solve it. Therefore, Marin even thought of a solution for them - to rob the tributary ships of other Ming vassals......

In this way, Portugal can definitely get the precious goods such as porcelain and silk that they want. However, the relationship with the Ming Dynasty will be more rigid - not to mention the younger brother of the family, but also to rob the goods of other younger brothers...... With the characteristics of the Ming Dynasty to save face, Portugal will definitely not be forgiven......

When the time comes, if Portugal wants to obtain the goods of the Ming Dynasty, there is only one way to smuggle. However, this road is very difficult, because it is smuggling, and the scale must be large. Moreover, the bid will certainly not be low. Otherwise, the smugglers of the Ming Dynasty would not have risked great danger to trade with the Portuguese.

As for Marin, he will pay tribute to the Ming Dynasty on Taiwan Island, plus offer sweet potatoes in exchange to obtain the right to legally enter the Ming Dynasty for procurement.

At that time, there will be two channels for obtaining goods from the Ming Dynasty in Europe - goods obtained through the smuggling channels of the Portuguese, and goods legally purchased by Marin......

The two goods are similar, but the cost is very different. Ma Lin remembered that in the last years of the Ming Dynasty, the Spaniards purchased silk sent by smuggling merchants in Manila for 240 taels per quintal of raw silk. But in the Ming Dynasty, the price of a load of raw silk is only a few dozen taels. Even if the Dutch occupy Taiwan Island and are so close to the mainland, the purchase price is as high as more than 140 taels per quintal, which is more than twice the normal price of the Ming Dynasty.

Therefore, when the time comes, although the same goods of the Ming Dynasty, the purchase cost of Marin is less than half of that of the Portuguese, and the profit obtained is much higher than that of the Portuguese.

As for the Portuguese have an opinion? Marin had already given himself the colonial rights of the Japanese archipelago, the Ryukyu Islands, and the island of Taiwan through an agreement signed at the Holy See.

When the time comes, Marin will trade with the Ming Empire in the name of a colony, what can the Portuguese say? Marin did have the right to colonize the islands, and Portugal recognized it. Could it be that you can still prevent Marin's colonies from trading with the Ming Empire?

As for the Portuguese themselves, they can't get the trade rights of the Ming Empire, what does it have to do with Marin?

……

In the final analysis, it is the Portuguese who are not familiar with the national conditions of China. In the beginning, they treated the Ming Empire in the same way that they treated ordinary small indigenous countries. After being hurt by the Ming Dynasty, he faced up to the strength of the Ming Dynasty. Then, the idea of obtaining a trade license through bribery came to mind.

But when this is compared with Ma Lin, the gap immediately came - Ma Lin was a Chinese in his last life, and he didn't know anything about the Ming Dynasty?

Therefore, Marin is destined to take the lead. Moreover, it was possible to bribe important and bigwigs to secretly stumble the Portuguese. By then, even if the Portuguese had figured out the way to bribe, the important people had already been taken care of by Marin. If they want to bribe, they have to have a door......

……

Columbus's debriefing was very simple, and he mainly recounted some of the observations during the voyage. But will Marin know less than he does? Marin, who had both history and geography in his previous life, was very familiar with world geography. What Southeast Asian climate, local folklore, don't be too proficient in it. However, out of respect for Columbus, Marin still pretended to be very interested and listened to Columbus's report.

Then, there's the most important thing – Columbus handing in his logbook......

This is the most important because it is an important reference that will be needed for later navigation. In particular, the coordinates were the most important reference for later captains to sail.

In addition, there are some special climates that need to be noted, as well as reef distribution points, which are also important.

Until there is no sonar for underwater reef exploration, it is better to follow the ready-made routes explored by previous people. As long as you check the coordinates and follow the map, there will be no major problems.

In fact, Marin also made a great contribution to this voyage. His greatest contribution was to warn that during the peak typhoon season in summer and autumn, it is best not to take the South China Sea route lightly. If you encounter a typhoon, God will not be able to protect you......

Therefore, Marin demanded - to take the South China Sea route, preferably in the first half of the year. Because, typhoons mostly occur in the second half of the year. As long as you don't encounter a typhoon, you will lower the sails in case of strong winds, and there will be no major problems. As for the problem of sinking on the rocks, there is also a solution - that is, multiple ships act together. If one ship runs aground, the other ships come to the rescue. The real danger is that a single ship goes to sea. No matter what danger you encounter, you are dead. Because, no one else saved them......

……

After sending off Columbus, Marin immediately ordered another seafaring god, Amerigo, to be found.

Amerigo came to Marin's office, and before he could take his seat, Marin said in a loud voice:

"Amerigo, are you ready to take another route to the Eastern Empire?"

Amerigo hadn't sat down yet, but he immediately rebounded and stood up straight. Then, with a serious face, Amerigo replied:

"Yes, Grand Duke, I'm ready! I've been waiting for this day for a long time, and I can go at any time! ”
