In fact, the Portuguese were very envious of Marin's method of using the island as a territory to claim his vassal to the Ming emperor, and they also wanted to learn from it.

However, they didn't know that the reason why Ma Lin was able to pass and become Daming's own person was not because he was willing to be a vassal, but because he offered sweet potatoes, a high-yield crop. For the Ming Empire, which is based on agriculture, Ma Lin's move is very crediting, and he is naturally qualified to become the "own person" of the Ming Dynasty.

Portugal is different, and the Portuguese do not have food to offer with this artifact, but only know how to use money to buy things. Such a person is dispensable for Daming, and naturally he can not be a bird.

What's more, Portugal actually occupied the capital of the Ming Dynasty's younger brother Manchuka Kingdom (Malacca Kingdom), and also occupied a large amount of the younger brother's territory. This would be a slap in the face of the Ming Dynasty, if it weren't for Liu Daxia hiding the navigation charts, the belligerent Emperor Zhengde almost wanted to restore the treasure fleet and go south to compete with the Portuguese.

Fortunately, the most important enemy of the Ming Empire at the moment is Mongolia, and Zhengde is now preparing for the Mongol war, so he did not have trouble finding the Portuguese who occupied Malacca.

However, the Ming court sent envoys several times to ask the Portuguese to withdraw, but the Portuguese refused. At this moment, the face of the Ming Empire could not be hung up. As a result, it was ordered that the Portuguese should be completely forbidden to come to Daming, and that any officials who colluded with the Portuguese should be severely punished. As a result, the two sides completely turned their faces.

The Portuguese were also depressed, if it weren't for the discovery of the huge reserves of super tin mines in Kuala Lumpur, they would have given up Malacca. It's a big deal, go and occupy Luzon Island, learn from Marin and give the Ming Dynasty a vassal state. But the existence of Kuala Lumpur's super tin mine makes the Portuguese really unable to let go. Therefore, I can only watch and turn my face with Daming.

At present, since the two sides cannot live in peace, the Portuguese government and opposition have begun to discuss how to deal with it.

Obviously, without intending to abandon Malacca, Portugal and the Ming Empire had no possibility of peaceful coexistence. However, the Portuguese were reluctant to give up the trade benefits of the Ming Empire.

In the end, the Portuguese government and the opposition reached a consensus, and Portugal planned to send a fleet to the Ming Dynasty, attack the coast of Fujian and Guangdong, and force the Ming Dynasty to make concessions.

The Portuguese were not as arrogant as the Spaniards, and would not have thought that they could conquer the Ming Empire by sending a fleet (historically, the Spaniards really intended to send more than 10,000 people to conquer the Ming Empire). Of course, the reason why the Spaniards came up with such a brainless plan was probably carried away by the subjugation of the Aztec and Inca empires with a small number of people.

But the Ming Dynasty and those barbarian empires are not the same thing at all, whether it is the Aztec Empire or the Inca Empire, there are no metal weapons, no cavalry, and no firearms. But the Ming Dynasty has all of them, although the combat effectiveness of the southeast guard post of the Ming Dynasty is very bad, but the northern border army is still very strong. Therefore, when later generations of Chinese people heard about this plan, they all thought it was extremely funny.

The Portuguese were not as self-defeating as the Spaniards, but their ships surveyed the Ming coast until the Ming navy was mediocre. Although there are many ships, they are mainly small boats, and they are still at the level of broadside warfare.

The Portuguese government and the opposition believed that if a powerful fleet of 30 warships was dispatched, not to mention that it could defeat the Ming Dynasty, there would be no problem in destroying the Ming Dynasty's naval divisions. Once a huge advantage was achieved in a naval battle, there was no need to worry about the uncompromising Ming Dynasty......

Therefore, the Portuguese concentrated their national forces and formed a fleet of 30 warships of two or three hundred tons. The battleship was equipped with a lot of furlong cannons, which were ready to be used against the Ming Dynasty sailors.

And the commander of this expeditionary fleet was none other than the famous Da Gama......

……

When Marin's spies stationed in Lisbon learned the news, they hurriedly released carrier pigeons to report to Marin. After Marin received the report, he was also dumbfounded, and the Portuguese played a big game......

Marin shook his head and smiled, because he knew that the Ming Dynasty was a country that would never give in. Even if the Portuguese fleet really wiped out the sailors, the Ming Dynasty would never give in. What's more, the current Emperor of the Ming Dynasty is an extremely warlike Zhengde.

So, the Portuguese will not get the results they want. Even if it has the upper hand for a while, it will anger the Ming Empire. When the time comes, the Ming Empire will fight with the strength of the whole country, and the Portuguese will definitely not be pleased.

……

However, after thinking about the consequences, Marin's face changed......

Why? Because Marin thought that if the Portuguese really angered the Ming Empire, Zhengde might be desperate to develop a navy. When the time comes, the Ming Dynasty has a navy, and it is likely to go to sea to grab benefits.

After all, if there is a real fire with Portugal, no matter how brain-dead Liu Daxia is, he must take out the navigation charts and shipbuilding materials. Otherwise, it will inevitably be stinking for 10,000 years.

When the time comes, the Ming Dynasty, which has restored the treasure fleet, will easily come to "Zheng He's voyage to the West" a few more times. Once the people of the Ming Dynasty go abroad, what is the matter with Marin?

Perhaps, when Marin sent a large army to invade Japan, the Japanese king asked the Ming Dynasty for help, and the Ming Dynasty treasure fleet would also intervene.

Marin was not afraid of the strength of the Ming Dynasty fleet, but was afraid that the two sides would turn their faces and cut off the trade route......

……

Therefore, the Ming Dynasty could not lose this battle. Otherwise, the enraged Ming Dynasty may explode the treasure ship. Once a treasure ship is built, it will certainly not rot in the harbor.

In order to ensure that the Ming Dynasty could win, Marin could only find a way to secretly help the Ming Dynasty......

After thinking about it, Marin finally decided to send someone to report to the Ming Dynasty in advance, and at the same time, send a batch of 12-pounder Napoleonic cannons to the Ming court, and even dedicate the method of casting this cannon to Zhengde.

At the moment, the Portuguese warship was not too big, and the main gun was also 12-pound. If the Ming Dynasty had a batch of 12-pounder guns, it would not be afraid of the Portuguese warships. Even if there are not a few cannons placed on the Ming Dynasty warships, they can't support the Ming Dynasty sailors. A ship is equipped with three or four doors, and hundreds of ships are thousands of doors, and they are not afraid of small Portuguese warships at all.

Therefore, Marin sent people to load 20 12-pounder Napoleonic cannons, and sent a craftsman who knew how to cast cannons with clay film (iron mold casting cannons are a secret of the Beihai State and are not passed on), and personally went to Daming to instruct the craftsmen of Daming's Ministry of Engineering to cast 12-pounder Napoleon cannons.

Marin's men took the route to Panama and then across the Pacific. Although the distance was longer, it was faster than the Portuguese fleet because of its smooth sailing in the Pacific. As long as the Ming Empire was prepared in advance, the Portuguese would not be pleased.

Of course, Marin is not concerned with whether Portugal can take advantage. He was just worried that the Ming Dynasty would restore the treasure fleet, and as long as the treasure fleet was not restored, the trade of the Ming Dynasty would still be monopolized by him. This is a huge profit, and there is no room for loss......
