Thinking about it carefully, Ma Lin felt that it was very necessary to open up the route of Daming as soon as possible. Needless to say, wheat with a shorter growth cycle is a must. In addition, Taihu pigs with many cubs and fast growth are also needed by Marin.

In addition, tea marlin is also in demand. Most of the European aristocrats were carnivores, and their diet was greasy, and they needed tea to clear their greasy. Moreover, Marin's English-style milk tea, that is, with cane sugar and milk, is simple but delicious, suitable for the tastes of all kinds of people. Moreover, it can also be sold with sucrose, which can be described as killing two birds with one stone.

As for silk and porcelain, although they are not urgently needed, they cannot stand the likes of Europeans. As long as you ship it back, you can make a lot of money.

Marin's only concern was whether there was so much gold and silver in Europe to buy high-end consumer goods such as silk and porcelain from the Ming Dynasty. You know, there is no goods in Europe that the Ming Dynasty urgently needs. Therefore, if you want to buy silk and porcelain from the Ming Dynasty, you must spend real money, and it is a large price.

Although Marin came up with a way to use perfume to open the Daming market, the output of perfume was limited after all. If you want to avoid serious entry in the trade with Daming, you have to think of other ways.

At the beginning, the British solved this problem by adopting the evil method of selling crows. But Marin would certainly not do this, and besides, the Ming Dynasty was not a Manchu Qing dynasty, and it was impossible for a foreign country to do so.

So, Marin hit the idea on the head of Japan. Coincidentally, Japan now happens to be in the Warring States period of village chiefs, and the country is in chaos. And the famous Iwami Silver Mine has not yet been developed.

Marin's plan was to take advantage of the civil strife in Japan and take the opportunity to send troops to capture Iwami Ginzan in Iwami Province. As for those village chiefs of the Warring States of Japan? Marin believed that a few thousand musketeers would be enough to hold Iwami Ginzan.

Don't look at the little devil's samurai martial arts are good, and he can go to the southeast coast of the Ming Dynasty to scourge, but that's useless, because, "no matter how good the kung fu is, you can knock it down with one shot"......

Even Ip Man, who "I'm going to fight ten", had to bow his head and admit his cowardice in the face of the little devil's 38 big gun. Otherwise, no matter how good the kung fu is, it will be destroyed by one shot.

If it was a close fight, the musketeers would not be able to defeat the Japanese samurai. However, the role of the musketeer is to keep the other side from approaching. In the face of a platoon of guns, no matter how high the martial arts are, it is in vain. If the castle walls can be built, a few thousand musketeers will be enough to withstand the attacks of tens of thousands of samurai, and they will have the upper hand. After all, the Musketeers are the best at defending......

As long as the extremely rich reserves of Iwami Silver Mountain are developed, Marin will not be short of silver. In Daming, silver is scarce and highly valued. When the time comes, Marin can spend the devil's silver to buy the goods he wants in Daming, and he can also have a large amount of surplus. At that time, the merchant ships under his command could not only bring back a large amount of silk and porcelain, but also a large amount of silver produced in Japan to meet the needs of European coinage.

In addition, Japan is also rich in copper mines, and since the late Ming Dynasty, Japanese copper has become an important commodity for Japan's export trade, and it is sold to various places by Japanese ships and Dutch merchant ships. If the copper produced by Sweden's Faylen copper mine caused the first sharp drop in European copper prices, the second sharp drop in European copper prices was caused by the fact that Japanese copper was brought back to Europe by Dutch merchants. Since then, the price of copper in Europe has gradually decreased, gradually approaching the level of the East, and is no longer high.

Of course, Japan's gold production is also amazing. For example, the gold reserves of Sado Island and Kagoshima are also very large, both of which are hundreds of tons. It's just that the Ryokari gold mine in Kagoshima is under the control of Japan's most powerful Satsuma domain, and it is much more difficult to capture than Sado Island. But the Ryokari gold mine also has its advantages, which is that the gold content of this gold mine is very high, reaching a staggering 80 grams per tonne (ore). The first of the world's top ten gold mines, the Indonesian Glasberg gold mine, has an ore gold content of only 0.703 grams per ton. The difference in gold content between the two is a staggering 113 times. What does such a large difference in gold content mean? Means a huge difference in the cost of extraction! In addition, if the Glasberg gold mine produces one ton of gold per year, the Ryokari gold mine can reach 113 tons with the same amount of labor......

Therefore, for the current situation of low mining technology, the production efficiency of mining super rich ores such as Ryokari gold ore is obviously much greater. Generally, gold mines pay a lot of manpower and material resources, and the annual output of gold may only be one or two tons, but the Ryokari gold mine can achieve the same level of one or two tons of gold per year with less labor, which is the gap.

Of course, this refers to the rich mine under the Lingkari gold mine. In fact, there are two gold mines in the Ryokari gold mine. One is a gold mine on the surface, which is an ordinary gold mine with low gold content. And the Ryokari gold mine underground is the real super bonanza. As long as you find that surface mine, you can continue to drill holes and explore to find that underground bonanza.

As for the Satsuma Domain, which was a powerful vassal state, Marin was actually too worried. The powerful Satsuma Domain in Marin's impression was actually the Satsuma Domain after the maritime trade began. Since the beginning of the trade with the Dutch, the Satsuma Domain, which was located in the southeasternmost part of Japan, actively participated in maritime trade, accumulated a large amount of capital, and became one of the richest feudal states in Japan at that time. However, it was not until 1592 that the trade in seals began. The current Satsuma Domain is just a village chief-level feudal state with a slightly larger land area, and its economy mainly relies on fishing. Marin thought about it and felt that it would not be difficult for him to conquer the Satsuma Domain if he sent a few thousand more people over......

……

It's just that to run Japan and beat those Japanese village chiefs, you have to wait for the cement road in Panama to be repaired. Otherwise, the traffic is not very convenient...... Marlin scratched at his hair in anguish......

While eating lunch, Marin had been thinking about things and accidentally knocked over his golden plate. So, the servant helped Marin change another piece of food. However, this suddenly gave Marin infinite inspiration......

"Change the food...... Change ......," Marin muttered. After a while, Marin suddenly slapped his thigh and said:

"yes, I'll try to think differently!"

Then, he pushed away the plate and hurried back to his office to think of a new approach......

Previously, Marin was limited by the Panamanian road, and always felt that he could not sail until the Panamanian road was repaired. However, with the technology of this era, it is estimated that it will not be possible to cut down forests and build a concrete road of 60 or 70 kilometers in Panama in two years, perhaps even longer.

However, if you really have to wait for two years, Marin feels that the daylily is going to be cold.

Moreover, in any case, even if the concrete road across the isthmus in Panama were repaired and a port was built on the side of Panama City, it would be necessary to take ships from the Atlantic Ocean around the Strait of Magellan, the southernmost point of the American continent, and then go north to Panama City!

So, in any case, sending the fleet south, and bypassing the southernmost tip of the American continent, this process is unavoidable.

That being the case, it is better to act late than to act early. Marin decided to send Columbus to lead the fleet south along the east coast of the South American continent, to the Strait of Magellan, and then to the west, around the west coast of the South American continent. Then, head north in the direction of Panama......

However, on the way, Marin plans to find an outlet for a large river on the Chilean coastline and establish a transit port. This port, in the future, will become a transit port for Marin's ships, and at the same time, it will also be a fresh water supply base for the development of Chilean saltpeter.

Marin knows that Iquique, the outlet for Chilean saltpeter, has not rained for hundreds of years, and fresh water is also dependent on ships from the outside world.

Therefore, if you want to develop saltpeter in the Chilean desert, you must first find a fresh water supply base in the central region of Chile. Large quantities of fresh water are then loaded in wooden barrels, heated and sealed, and stored for months before being sent to Iquique, where they can provide enough fresh water to Iquique and inland saltpeter mines.

And after obtaining this transit port, the ship can also continue north to find the location of Panama City. That way, you don't have to wait for the concrete road in Panama to be completed.

Even before the concrete road was completed, Marin could send a fleet of ships to Panama City to build a port and castle. By the time the concrete road was paved, the port and castle were almost finished. Then, you can directly use Panama City as a base to start a new voyage to the west, and go directly to find the route between Daming and Japan......

I'm sorry, I'm just sleepy, and I'm asleep on the table again, and I'm freezing to death. I woke up in the middle of the night and continued to finish the code, so everyone waited for a long time. Alas, I'll squint in bed for a while, and I'll have to squeeze the bus again, and I'm going to doze off during the day today......
