, Dolgon brought two "days" himself, one is called Ito Ren, the other is called little Linnaeus, both of which were recruited by Dolgon after he came to the "day", and they are Dorgon's assistants. They're all the kind of people who have milk and are mothers, and they don't care who they give their lives to.

Zhou Zhengyu said: "The weather is very good, so we will discuss things on the deck. ”

Dorgon said, "Okay. Kobayashi, you give Commander Zhou a detailed introduction to the situation on Sado Island. ”

Tong Zhengyu shook his head and said, "No need." ”

He took out a document, handed it to Dorgon, and said casually, "This is what the Governor told me to give you, and he said that after you read it, you will understand what to do." ”

Dolgon, a little confused, opened the information and read it carefully. There is nothing special in this information, it is all about Sado Island. However, it was this brief that made Dorgon very curious. Because, this brief is more detailed and far-sighted than his investigation on the island.

According to Zhang Zhun's description, Sado Island is a large island on the northern coastline of Japan, with an area of about 100 square kilometers, which is equivalent to Chongming Island in the Ming Kingdom. However, Chongming Island is an island island in the Yangtze River Delta port, with the destruction of the environment in the upper reaches of the Yangtze River, the turbidity of the Yangtze River water quality, in recent centuries has been rapid, and the exhibition area has been expanding. Sado Island, on the other hand, is an island outside of Japan that has existed for a long time.

The distance between Sado Island and Honshu Island is very narrow, slightly wider than the Qiongzhou Strait of the Ming Kingdom (Hainan Island) and the Big 6. If the entire land of "Japan" is like a pine caterpillar, Sado Island is on the ridge behind it. If the "Hichimoto Islands" resemble a large lobster, "the six places in the Kanazawa area protrude northward like a fin back," and it is behind the fin back. The island of Honshu, which slopes from north to southwest, is like a solid wall, blocking most of the east and south, making this area very open from the south to the north.

Of course, none of this is the most important thing. On top of that, there are a lot of gold and silver mines on Sado Island. In addition to Iwami Ginzan, this is the largest gold and silver producing area in Japan. In terms of pure gold mines, Iwami Ginzan is not as good as Sado Island. It is precisely because of the large amount of gold produced on Sado Island that the price of gold in Japan has been very low.

At the peak of the gold mining period, Sado Island could dig about 10,000 taels (about 40 tons) of gold every year.

Forty tons of gold, according to the price of silver in the Ming Kingdom, is exchanged for more than one million taels of silver. In other words, Sado Island can produce more than one million taels of silver every year. Such a number, of course, is considerable. If you add the production of Iwami Ginzan, "it will be even more abundant."

In the Ming Kingdom, under normal circumstances, a tael of gold can be exchanged for about two to ten taels of silver, and during the Wanli period, the maritime trade was rapidly developing "a large influx of overseas silver, resulting in a continuous decline in the price of silver, and the price of gold repeatedly hit new highs." By the fifth year of Chongzhen, one tael of gold can already be exchanged for more than thirteen taels of silver. There is even a trend that continues to rise.

Because of the rising price of gold, "Zhang Zhun is of course crazy to find the origin of the gold mine." In Shandong, there are many gold mines, and the gold mines in Zhaoyuan and other places are still relatively famous. It's a pity that the Zhaoyuan gold mine was opened by the Yuan Dynasty and the Ming Dynasty. Coupled with the fact that the Tiger Ben Army did not want to die, it dried up and fished, and it is estimated that it will not take many years for the Zhaoyuan gold mine to dry up.

In the long run, Zhang Zhun must look for more untapped gold mines. Sado Island is here that it came into Zhang Zhun's sight. In fact, at the beginning, Zhang Zhun was still staring at Iwami Yinshan. However, Iwami Ginzan is the object of the shogunate's key protection, and it is in the inner 6 of the "Day", which is not easy to control. Considering all the conditions, he had to start with Sado Island.

For the Tiger Army, Sado Island is indeed a rare and good place. It was basically on the periphery of the shogunate's rule, and the shogunate army was only a symbolic station, with no real combat effectiveness. Sado Island is also isolated from the sea, separated from Honshu Island by a strait. The Tiger's naval strength is strong, and it can basically contain the Japanese navy. Therefore, after the Tiger Army took Sado Island, the shogunate army's counterattack, even if they wanted to be brutal, they couldn't be brutal.

After reading the information, Dolgon looked at Zhou Zhengyu suspiciously, he suspected that this information was made by Zhou Zhengyu himself, and then lent it to him in the name of Zhang Zhun. Otherwise, how would Zhang Zhun, who was thousands of miles away, know about Sado Island? And I know it in such detail.

Of course, Zhou Zhengyu didn't know Dolgon's guess, and when he saw Dolgon's suspicious gaze, he followed. "Do you have any questions?" ”

Dolgon said in disbelief: "Can Sado Island really dig up 10,000 taels of gold every year?" Ten thousand taels of gold, that's more than a million taels of silver! ”

Zhou Zhengyu said affirmatively: "Lord Governor said so, it should be right. ”

Still a little disbelieving, Dorgon said: ...... But as far as I know, there don't seem to be so many gold mines on Sado Island! Even if you count all the silver mines, it is impossible to have such a high output! ”

He said to little Linnaeus, "Tell me about it." ”

Xiao Linnaeus is obviously a standard Japanese traitor, very obedient, and immediately stood up when he heard the words, and explained in detail. He knows a lot about Sado Island. It can be seen that Dolgon is also paying attention to Sado Island.

Sado Island is not unoccupied, there was a Sado country on the island a long time ago, and the history of the indigenous people is as long as the history of Honshu Island. However, Sado Province is indeed too small, and the total population may be less than 10,000. At the time of the Sengoku period, Sado Province had always existed as Echigo Province, a large country dependent on the island of Honshu. Later, the Tokugawa shogunate basically unified the whole country, and it also affected Sado Island.

Twenty years ago, Sado Island became the "Tenryo" (i.e., Governor) of the Tokugawa Shogunate, and the Shogunate set up a Kaniyama Prefecture here to be responsible for the development of gold and silver mines on Sado Island. Therefore, it can be said that the shogunate also noticed the gold and silver of Sado Island. The location of the shogunate officials is in Aikawa Castle to the west.

Zhou Zhengyu cautiously asked, "How many troops are stationed here in the shogunate?" ”

Dorgon replied, "Five hundred."

Zhou Zhengyu nodded and said categorically: "Okay!" Let's go to Aikawa Castle right away! Ascend 6 there! Let's take control of Sado Island first! ”

At the sound of the order, the fleet immediately turned around and headed north, approaching the position of Aikawa Castle. Soon, they reached the sea opposite Aikawa Castle. Looking through the clairglass, the so-called Aikawa Castle is actually a small fortress, plus a small port, and a scattered market. Vaguely, you can see that there are some people coming and going. This is the busiest place on Sado Island.

Now that a large number of warships arrived, the shogunate troops stationed at Aikawa Castle hurriedly fired warning shots. The people on the shore also hurriedly looked for a place to hide. The weapons of the shogunate army were all imported from Portugal, and there were quite a few so-called iron cannons (i.e., muskets), and after the warning shots were fired, more gunshots began to crackle. Of course, their weapons are a bit far behind the Tiger Army.

"Three salvos!"

"Fire!"

Zhou Zhengyu shouted awe-inspiringly.

"Tom tom!"

"Tom tom!"

"Tom tom!"

Moments later, sixteen saber-tooth ships opened fire together.

The first salvo was nearly 300 pieces of artillery, and the fierce sound of artillery shook the entire sea in front of it. The people of Sado Island have always been accustomed to peaceful days, but now, when the deafening sound of cannons is heard, they are almost all frightened.

The shogunate was stationed in Kanayama in Aigawa Castle, and the person in charge was called Junjiro Koizumi. He was enjoying tea when he suddenly heard the sound of cannons in the distance, and he was stunned. Immediately after, countless hailstones fell on the roof of the fortress. The roof of the tea room where he was located was also smashed by shells. Fortunately, his life was too big to be hit.

Almost subconsciously, Junjiro Koizumi hurriedly ran out of the tearoom and hid behind the walls of the fortress. He escaped quickly and was lucky, and he narrowly avoided the bombardment of the shells, but the followers behind him were not so lucky.

In the process of running, Junjiro Koizumi's three entourages were all smashed by solid bullets, and they immediately turned into a ball of meat sauce. The most exaggerated thing is that there is still an entourage, whose head is smashed off, and he runs desperately with Junjiro Koizumi until he runs twenty or thirty meters, and then staggers and falls to the ground.

Junjiro Koizumi just turned around and saw this scene, and was suddenly frightened to the point that his brain went blank, and he stuck to the back of the city wall, shouting hysterically around him: "What's the matter? What's going on? Who's fighting? ”

"Tom tom!"

"Tom tom!"

"Tom tom!"

Before the words fell, another series of cannon shots came.

Junjiro Koizumi was frightened and hurriedly curled up behind the city wall, not daring to move.

The falling cannonball smashed all the debris behind him. Even the stone table, which was as thick as a palm, was smashed to pieces. The house behind him, not only the roof was smashed, but even the walls were smashed. Those who couldn't hide were hit by a series of iron bumps, either dead or injured, and the scene was chaotic.

After a while, an entourage hurriedly arrived at Junjiro Koizumi's side and kept reporting something to him. However, no matter what he reported, Junjiro Koizumi felt that he hadn't heard. He only saw the shape of the other party's mouth, but could not hear the other party's voice. Everything in front of me has changed from color to black and white! ~！
