If I fail to overcome the tribulation, I can only return to the Ming Dynasty and become a prince.

Chapter 173 Linggao Gold Mine
When Marco Polo wrote "Marco Polo's Travels", he once described a country full of gold.

"It is said that there is gold, and its quantity is endless. The monarch has a large palace, and the roof of the palace is made of fine gold...The houses of the palace are paved with gold bricks, replaced by stone slabs."

This country whose houses are paved with gold bricks was the Japanese country that was still in the Kamakura Shogunate period.

It is definitely an exaggeration to boast that the house is paved with gold bricks. Although the floors of the Chinese imperial palace are indeed paved with "gold bricks", they are not made of real gold, and it is even more impossible in the Japanese country.

As for the roofs of the palace being made of fine gold, this is actually possible.

Because the gold reserves of Japan, a small country, are so high that they can actually use gold to decorate their houses.

If Zhu Zhanjun remembers correctly, Ashikaga Yoshimitsu, the current Japanese shogunate general who conquered barbarians, gave up his position as general to his son to become a monk. He built a Luyuan Temple in Kyoto of the Japanese country. There was a three-story attic in the temple. The whole body is covered with gold foil.

Although this level of luxury is not impossible for the Ming Dynasty across the sea, at least Zhu Yuanzhang rarely experienced luxury when he built the Forbidden City in Nanjing. The decorations in the palace were all made of real gold, and the overall consumption was not Less than building a three-story loft.

But this still reflects the rich gold reserves of this island country.

In fact, according to later statistics, from the Warring States Period of Japan to modern times, this island country, which is less than one province in China, has dug out at least thousands of tons of gold and tens of thousands of tons of silver.

Just the three mines of Hisikari, Sado and Konomu produced at least [-] tons of gold and more than [-] tons of silver. The Japanese country's mineral reserves in this area are staggeringly rich.

Although this is the total amount that has been excavated over hundreds of years, the fact that there is so much gold and silver buried underground makes the Ming Dynasty, which is extremely short of silver across the sea, very envious.

I was so envious that six Ming vassal kings came across the sea to incorporate this island country into the Ming Dynasty and let the people of Japan bathe in the grace of the king.

The Linggao gold mine on Kyushu Island chosen by Zhu Zhancheng was the only large gold mine in operation in the Japanese country in later generations, and it was also the largest gold mine in the Japanese country. From the time of discovery to the time Zhu Zhancheng crossed over, 200 million gold mines were mined. Many tons.

At first glance, it may not seem like a big number, but more than 200 tons of gold is already a very outrageous number.

In particular, this large gold mine has not been completely dug even in later generations, and there are still at least more than 100 tons of reserves waiting to be mined.

In this era, this gold mine has not been discovered at all, and the surrounding gold mines such as Kushikino, Akaishi, Iwato, and Kasuga are also waiting to be discovered and mined.

An important reason why these gold mines were discovered only in later generations is the depth of burial of these gold mines.

For example, the burial depth of the main vein of the Linggao Gold Mine is approximately between 200 and [-] meters. This depth is very difficult to mine in this era.

However, there are also some broken veins on the surface. Although these veins are not coherent, have poor mineralization continuity and small ore bodies, their burial depths are also relatively shallow. They are suitable for small-scale mining when technical conditions are insufficient. Mining.

As for the large ore veins buried deep underground, not to mention the difficulty of mining, smelting is also a troublesome matter.You must know that in this era, the Japanese nation did not even have the technology to refine silver, such as the gray blowing method. This technology could not be introduced from Korea until the end of the Warring States Period.

Of course, for Zhu Zhanqi, the depth of burial and the difficulty of mining and smelting are not problems.

If he were in the world of immortality, he could even directly communicate with the earth veins, and then use great magic power to pull up the entire gold mine from the ground, turning the deep veins into shallow veins, which can be mined directly in the open.

If it is too troublesome, it is not impossible for Jindan Zhenren to directly extract all the mineral deposits in the entire vein.

Otherwise, where did the veins in Zhu Zhanqun's cave gourd come from?This is not something that the Cave Sky Gourd grew by itself.

Although in this world, due to the lack of spiritual energy, Zhu Zhanqi needs to be careful when using powerful spells. For example, the lightning strike on Fukuoka City caused him to consume too much real energy. After the war, he immediately went to the hot springs to check himself and the Dragon Balls. In addition to the problem, another factor that was not too important was that he needed to take a break to recover his true energy and mana.

If you were in the world of cultivating immortals, this would not be a problem at all. Even if Zhu Zhanchun washed the entire Kyushu Island with thunder, his cultivation would be enough to support him to complete such a thing.

But in this world that lacks aura, chopping down a castle cost Zhu Zhanquan more than two-thirds of his mana. This inevitably made him need to think carefully before using spells to ensure that he could afford the consumption of mana. .

After all, if he really uses up all his mana and true energy, it doesn't mean that he can't recover. It's just that it's still very uncomfortable for Zhu Zhanchun in that state, and even if he recovers with the spiritual energy provided by the cave gourd, the recovery speed will not be as fast. Not fast.

Therefore, Zhu Zhanqi just asked the palace officials to summon craftsmen who were good at mining and sent them to Lingjia, where the Lingjia gold mine is located, and asked them to find the mines themselves and arrange matters related to mining and smelting.

As for Zhu Zhanjun himself, he planned to use great magic to lift the vein upwards after these craftsmen confirmed the location of the Lingjia gold mine, in order to reduce the difficulty of mining.

The officials of the royal palace naturally knew the reason why the six vassal kings of the Ming Dynasty raised troops against the Japanese country.

To put it mildly, only two feudal lords, Yan Wang Fan and Ning Wang Fan, were involved in Jingnan back then, and the other feudal princes were all waiting and watching.

In this war against Japan instigated by Zhu Zhankui, including his own Ming Dynasty, which dispatched six vassal kings and their royal guards at one go, this was a huge force that was not even available during the Jingnan period.

Obviously, these princes are not here to do charity and pass on the teachings of the sages to the Japanese people. What they want to do has always been clear, and that is to mine the countless gold and silver buried underground in the Japanese country.

For this matter, Zhu Di, Zhu Gaochi and Xia Yuanji in the court jointly suppressed the court, so that there was no objection from the government and the public. Later, they provided Zhu Zhanquan and other vassal kings with almost the same treatment as the emperor's personal expedition last year. Food and grass supplies.

It can be said that, except that the emperor's personal troops were not dispatched, this expedition against Japan was not much different from the imperial commander's personal expedition.

After the imperial court spent such a high price, the goal it sought was naturally to produce at least one million taels of silver a year.
