Li You did not aim at Kobayakawa Hideaki, who was closer to Tsushima Island, nor did he clean up Kobayakawa Hideaki's territory south of Kobayakawa Hideaki and Kato Kiyomasa, because these daimyo had suffered heavy losses in the process of invading Korea, among which Konishi Yukinaga was killed by himself off the coast of Busan, and all the 10,000 soldiers and horses under his command who went to Korea were annihilated, and Kobayakawa Jingtaka was also choked by Li Rusong when he invaded Korea for the first time, and about forty percent of the soldiers under his command were killed in battle; As for Kato Kiyomasa, he was first annihilated nearly forty percent of his troops in the first war, and then encountered the most cruel and difficult Battle of Ulsan in the second war.

In short, the forces of these daimyo have been almost lost on the Korean battlefield, so there is not much to attack, so Li You aimed at the Shimazu family of the Satsuma Domain in the southernmost part of Kyushu, and the Shimazu family did not contribute less in the two wars of aggression against Korea, the first time the head of the family, Shimazu Yoshihisa, sent his younger brother Shimazu Yoshihiro to lead 14,500 people, and the battle damage was close to sixty percent, and the second time Shimazu Yoshihiro could only lead 10,000 people, and then was defeated by Chen Lan and Li Sunsin and Lu Lianghai when he fled, Fleeing back with only a few dozen broken boats and a few hundred soldiers.

Although the losses of the Shimazu family are not less than those of the Kobayakawa family, the Konishi family, and the Kato family, the Shimazu family has one thing they lack, that is, the water division, throughout the Warring States period of Japan, the only people who have the water division are the Noshima Murakami Water Army, the Awaji Ataka Water Army, the Ise Nine Ghost Water Army, the Ouchi Family Water Army, the Niko Family Nasa Nisuke and the Shimazu Family.

Li You knew that it was impossible for him to completely conquer the Wa Kingdom with more than 30,000 people under his command, so his strategic goal was to first clean up these few sailors who still had some combat effectiveness, and let the inner and outer seas of the Wa Kingdom become the territory of the sailors under his command, and then continue to harass the mainland, and use the contradictions between the Kanto and Kansai regions to continuously weaken the strength of the Wa Kingdom, so as to achieve his own goals.

So after waiting for so long, when he felt that the time was almost right, he commanded his army to go to sea to the naval garrison of the Satsuma Domain, preparing to start with the Shimazu family's naval division.

Before Zong Yoshichi was happy, he received an order from Li You to lead all the ships of the Tsushima clan to attack the Shimazu clan with him.

It should be noted that the Wa Kingdom at this time was far from being a maritime country that was formed after the Meiji Restoration, and it was a mainland country that could only be said to live on islands, and the various daimyo did not pay much attention to the role of sailors, even if the above-mentioned daimyo were famous for their sailors, the sailors in their hands were far inferior to the Zheng Jiajun.

The foundation of the Sengoku naval army was basically based on pirates who raided the Seto Inland Sea and the coastal waters of Japan, such as the famous Kuki Yoshitaka, as well as Murakami Takeyoshi, Kurushima Dojima, etc., and the daimyo had water combat power by cooperating with these local snakes or recruiting An; With the exception of a few ocean-going merchant ships built for the needs of ocean-going trade, most of the remaining ships were just boxes suitable for fighting in the relatively calm waters of the Seto Inland Sea.

In this era, there are three main kinds of boats used by the Japanese sailors, the so-called "small morning, closed ship, and safe house", these three kinds of ships are flat-bottomed pulp boats, and the sail is its auxiliary power, and the sail is used in peacetime and the pulp is used in wartime.

Xiaozao is basically about ten meters, the form of the ship is different, but the maximum will not exceed forty meters, the house is basically the fire defense of the ship, and the size difference is not big. The main structure of this type of ship is to erect planks on the side of the ship for defense, and large ships will build closed cabins on the bottom of the ship, forming a peculiar box structure, and its main offensive methods are bows and arrows, and white-knuckle warfare on the side of the ship, with less firearms, let alone cannons.

Due to the stiffness of this box-shaped structure and strip-shaped hull, the larger the volume of this kind of ship, the more unstable the center of gravity, the worse the impact resistance, and the clumsy fat man, so there was a situation where Yi Sunsin was previously hoisted by more than 300 warships chasing the Japanese with thirteen warships.

In addition, it was not until more than ten years ago that the Otomo family purchased the first small Furlong machine from the Dutch and equipped it on the ship, but due to the high price and the structure of the Japanese warship did not have the conditions to equip artillery, the threat of the opponent's artillery could be ignored in future water battles; In the face of such an enemy, dispatching the Zheng family army is simply abusing vegetables.

Prior to this, Li You had inquired about the details of the Satsuma Domain, the Satsuma Domain was 605,000 stone high, which was considered the most powerful daimyo on Kyushu Island, according to the conscription standard of 600 people per 10,000 stone before Toyotomi Hideyoshi's conquest of Korea, the Satsuma Domain could take out an army of more than 36,000 people, but they lost nearly 20,000 people in Korea alone, and now it can be said that someone in the domain died in Korea, even if the proportion of Shimazu samurai is relatively high, and the family and the retainers are also more united, they can't draw more soldiers and horses, Therefore, the most critical problem in this battle is to find the location of the Satsuma Domain's water division.

At this time, although Shimazu Yoshihisa, the lord of the Satsuma Domain, had become a monk and gave up the position of feudal lord to his younger brother Shimazu Yoshihiro, the real power was still in his hands, and at this critical moment, he had to come out to discuss countermeasures with many retainers, who did not realize that the disaster was coming, but discussed another matter, seeing that the contradictions between the Kanto and Kansai princes were becoming more and more serious, and their own family had suffered heavy losses in the previous war, so they put the goal of expanding their power and obtaining resources on the Ryukyu Kingdom not far away.

Shimazu Yoshihisa originally planned to accumulate strength for a few years, constantly test the details of the Ryukyu Kingdom, and then when the strength was sufficient, send Shimazu Yoshihiro to lead a fleet to conquer the Ryukyu Kingdom and bring it under the rule of the Satsuma Domain; However, Shimazu Yoshihiro wanted to give this task to another person, Hisataka Kayama, a retainer of the Shimazu clan.

In history, it was he who led 3,000 people to attack the Ryukyus eight years later, and captured more than 100 people including the Ryukyu King Shangning, and his descendant Kayama Shiki participated in the First Sino-Japanese War, and became a naval admiral and the first governor of Taiwan.

But in this world, he didn't seem to have this opportunity, because Li You had already led the fleet of the Zheng family's army to surround the Shimazu family's sailors and was preparing to attack.

When the news came, everyone in the Shimazu family was stunned, and they quickly interrupted their deliberations and rushed to the port, but this movement also attracted the attention of a special person in the Satsuma Domain.
