It is worth mentioning that in order to facilitate the tribute and trade between the Ryukyus, Ming Taizu gave the Ryukyu Kingdom many large ships, and sent the shipwrights and sailors who went with the ships to stay in the Ryukyu Kingdom.

"The Fujian people have thirty-six surnames, and those who are good at boating make tribute."

These surnames are: Liang, Zheng, Jin, Cai, Mao, Chen, Lin, Zeng, Gao, Wu, Li, Ruan, Shen, Wei, Tian, Wang, Ma, Qian, Weng, Mu, Han, Zong, Kun, Yin, Cha, Wu, Xiang, Wu, Ji, Ying, Tao, etc.

Since the Hongwu and Yongle years of the Ming Dynasty, "the Fujian people were given thirty-six surnames, and those who knew the books were given doctors, and they thought that they were Gong Xie Si, and those who learned the maritime affairs were given general affairs, and they were always prepared for the guide." ”

According to the record of "Mingshenzong Record", most of these 36 surnames are from Hekou, Fujian, and those with excellent descendants study in Nanyong (Taixue), and after graduation, they are generalists, and then promoted to Changshi doctors.

It is also recorded in the "Famous Mountain Collection" that the Ryukyu Kingdom was "a doctor official, a chief historian, and a general officer." Si Gong also, Wenchen also, after passing the Chinese book and the 36 surnames of Fujian. ”

Li Yuntian was very surprised by the attack on Songjiang Mansion by the Japanese Invaders, because both Aoki Mingxin and Shan Hai Mitsutaka had already expressed their intention to surrender, how could they attack Songjiang Mansion at this time?

Although Li Yuntian didn't want to believe it, but things had happened, and in the face of the living facts in front of him, he could only plan countermeasures, otherwise not only his face would be affected, but also the reputation of the Ming Army's sailors.

"Xianggong, the concubine feels that this matter is very strange, unless those widows are crazy, aren't they afraid that the sailors of the Ming army will go to encircle and suppress them?" Seeing that Li Yuntian's expression became solemn, Lei Ting groaned and said, "Do you want our people on Ryukyu Island to check what happened?" ”

"No matter what the conspiracy is, since those robbers are looking for death, then Xianggong will fulfill them!" Li Yuntian couldn't help but sneer when he heard this, he naturally felt that something was wrong, it stands to reason that unless those would-be robbers had their brains in water, they would definitely not take the initiative to provoke him.

Anyway, Li Yuntian's holy decree was to exterminate the Japanese pirates, so the Japanese on Ryukyu Island were also within the scope of suppression, and he originally wanted to wait until the affairs on the small Ryukyu Island were settled, and then deal with the Japanese on the Ryukyu Island, but now it seems that those Japanese pirates want to force him to act in advance.

For Li Yuntian, since he was slapped hard, he would definitely return the blow in the shortest possible time.

"Pass my order, the sailors will set off for the Ryukyu Kingdom the morning after tomorrow, and take this opportunity to wipe out the Japanese invaders entrenched in the Ryukyu Kingdom, so that the Japanese will lose the last pedal to attack the Ming Dynasty at sea." After groaning for a while, Li Yuntian whispered to Lei Ting.

Li Yuntian wanted to personally lead his army to the Ryukyu Kingdom this time, first, to suppress the Japanese invaders, and second, to discuss with the king of the Ryukyu Kingdom the matter of establishing a military port on Ryukyu Island, and he wanted to use Ryukyu Island as a fortress to eliminate those Japanese who were rampant on the sea, and at the same time, to maintain strong military pressure on the Japanese to make them dare not act rashly.

This not only served as a deterrent to the Japanese people, but also served as a warning to the Japanese people, so that they could watch their own subordinates so as not to go wrong again.

So, under Li Yuntian's secret arrangement, two days later, in the morning, the people of the port got up and were surprised to find that many of the warships of the Ming army and sailors moored at the wharf were missing.

Since the people of Xiaoliuqiu Island did not know that Songjiang Mansion was attacked by the Japanese invaders, the people did not have the slightest doubt about the explanation of the martial arts, and no one would have thought that Li Yuntian would start a new war just after the Lantern Festival.

In Li Yuntian's view, the warplanes on the battlefield were fleeting, and since the Japanese on Ryukyu Island dared to provoke him, then he would take advantage of the carelessness of those Japanese to destroy them in one fell swoop, so that they would be punished as they deserved, and I am afraid that those Japanese would never have imagined that he would launch a counterattack so quickly.

"Lord Wang, I hope to hand over the matter of land warfare to us." Driving on the Mingyang on the rippling sea, Keiko Yamaguchi, dressed in military uniform, asked Li Yuntian to fight, looking quite high-spirited.

In order to distinguish themselves from the Japanese invaders, those who recognized Keiko Yamaguchi as their main prince have all changed into new military uniforms similar to the shobudo system.

After half a year of training, Keiko Yamaguchi's Japanese have become accustomed to the new military uniforms on their bodies, and at the same time, they have also adapted to the daily training of the martial arts.

Although the daily training is very hard, the food in the barracks is very good, and the standard of food treatment enjoyed by those Japanese is the same as that of the Ming army sailors on Xiaoliuqiu Island.

A middle-aged Japanese man with thin cheeks bowed down and stood beside Keiko Yamaguchi, his eyes full of expectation, he was the person Keiko Yamaguchi was looking for on Xiaoliuqiu Island, named Yamaguchi Kai, and Keiko Yamaguchi called him "uncle".

However, in Li Yuntian's opinion, Yamaguchi Hai was respectful in front of Keiko Yamaguchi, not like an uncle and niece at all, but like a lord and a subordinate.

Yamaguchi Hai is a leader of hundreds of Japanese bandits, and he has been looking for Keiko Yamaguchi in recent years, he never expected that it would be Keiko Yamaguchi who came to him, and there is also Li Yuntian, a big backer, and he was surprised and happy in his heart, with mixed feelings.

According to the report of the military attache who witnessed the meeting between Yamaguchi and Yamaguchi Keiko at that time, Yamaguchi Hai immediately knelt in front of Yamaguchi Keiko and cried loudly after confirming her identity, calling her "Miss", and only later called her "Keiko" at Yamaguchi Keiko's request.

From this, Li Yuntian can be sure that Keiko Yamaguchi is definitely a nobleman in Japan, but because he doesn't know the situation in Japan, and there are dozens of daimyo in various parts of Japan, it is not easy to guess Keiko Yamaguchi's identity.

In fact, Li Yuntian did not deliberately inquire about Keiko Yamaguchi's background, because when the time was right, Keiko Yamaguchi would definitely tell him the truth.

"Okay, this king will order you to be the vanguard of this eradication of the Japanese on Ryukyu Island, and you must wipe out all the Japanese on the island!" Seeing that Keiko Yamaguchi took the initiative to ask for battle, Li Yuntian nodded with a smile, he also wanted to know how effective the would-be were after the reorganization of Keiko Yamaguchi in the past six months.

"Don't worry, the prince will never let go of a widow!" Seeing that Li Yuntian agreed to her request, Keiko Yamaguchi couldn't help but breathe a sigh of relief, she also wanted to take this opportunity to test the strength of those widows under her.

"The attack on Matsue Prefecture by the Japanese is too strange, and since Aoki Akishin and Yamakai Mitsutaka have already expressed their intention to belong, there is a chance that they will not invade Matsue Prefecture on a large scale at this time, so this king now suspects that the people who attacked and harassed Matsue Prefecture were not the Japanese on the island, but the people of Kyushu Island in the Japanese country, and this time they deliberately wanted to confuse our sight and let me point the finger at the Japanese on Ryukyu Island."

Looking at Keiko Yamaguchi, who was eager to try her posture, Li Yuntian pondered for a moment and said, "They can make a windfall by doing this, and when they stop using, they also frame the charges to others."

"People from Kyushu?" Keiko Yamaguchi showed a look of surprise on her face when she heard this, she didn't expect Li Yuntian to think of this.

"This king has received news that high-ranking people from the Satsuma Domain of Wakoku have been frequently traveling between Kyushu Island and Ryukyu Island recently, and things will definitely not be easy according to this king!" Li Yuntian bowed slightly when he heard this, and replied quietly.

"Satsuma Domain!" Keiko Yamaguchi's face suddenly changed slightly when she heard this, if it was the Satsuma Domain, it was not without the possibility that Li Yuntian said.

Satsuma Domain, also known as Kagoshima Domain, Shimazu Domain. Appearance of the daimyo. It was part of Satsuma Province, Osumi Province, and Hyuga Province, and was located in southwestern Kyushu, part of today's Kagoshima and Miyazaki prefectures.

The Satsuma Domain was a large domain of 770,000 Ishitaka, the lord of the Shimazu clan, in the middle of the twelfth century, Yoshihisa ruled and served as the guardian of the Three Kingdoms, so he became the guardian daimyo, the Sengoku Daimyo, and when Yoshihisa was in power, he controlled most of Kyushu.

Speaking of the Satsuma Domain, then we have to say that the Satsuma samurai, the Satsuma samurai respected the strong, admired force, regarded cowardice, cowardice and illness as dung, respected a samurai who died on the battlefield for the lord, and spurned a samurai who escaped from the battle.

The Satsuma samurai can be said to be synonymous with excellent samurai, capable of fighting well and strong.

As early as the Muromachi period, the Ashikaga clan was shocked by the strength of the Shimazu army, and this phenomenon was further continued in the Sengoku period, and after the Satsuma sage, Shimazu Hishin Gong Tadaya, established a perfect samurai training code, the Satsuma Hayato became synonymous with invincibility.

The Satsuma Samurai have a glorious track record:

With basically no casualties, the Shimazu army won more with less, and broke the Hyuga Ito army in Kisakihara, beheading more than 900.

With 4,000 soldiers, he defeated the Hyuga Expeditionary Force of 30,000 people in Otomo Sorin, completely breaking the hegemony of the Otomo family in Kyushu.

In the battle of Okita Tsui, the Shimazu army of 4,000, the combined army of Arima and Omura of 3,000 (a total of 7,000) broke the Ryuzoji army, and the commander of the Ryuzoji army, Ryuzoji Takanobu was killed by Kawakami Tadajian, and the four heavenly kings of Ryuzoji Temple were killed in battle.

In the Battle of Tojigawa, 8,000 troops ambushed the Shikoku army (17,000 in total) that crossed the Tojigawa River, Tosa Nagamune's army, known as the strongest army in the world, was killed and wounded, the military commander Fu Senishi Hidehisa was wounded, the coalition army supervised the army Tokawa Tsubo was killed in battle, and the famous Tosa generals Kuwana Yoshinari, Furuyi Shige, and Morikin, the son of Nagamune's first family, were killed in battle.

Because the warriors of the Satsuma Domain were good at fighting and were among the best feudal clans, Keiko Yamaguchi was a little jealous of them.

It is worth mentioning that before the Meiji Restoration, the Satsuma Domain was the birthplace of the Shogunate Movement, and there were many famous people. After the Restoration, the Satsuma Domain mastered the navy, and together with the Choshu Domain, it was called "the army of Choshu and the navy of Satsuma", and the limelight for a time was unparalleled.

The earliest old Japanese navy was almost all from the Satsuma domain, and whether it was the Sino-Japanese War or the Russo-Japanese War, the three giants of the navy (the Minister of the Navy, the head of the Naval Command Department, and the commander of the Combined Fleet) were all Satsuma.

"The king now suspects that the Satsuma clan is connected to some people with ulterior motives in the Ryukyu Kingdom." Li Yuntian naturally knew how powerful the Satsuma Domain was, but he was not worried about this matter, but the complicated situation on Ryukyu Island was being used by the Satsuma Domain.

The reason why it is said that the affairs on Ryukyu Island are complicated, but I think that after the "Three Kings Period", the Ryukyu Island seems to be calm on the surface, but in fact there is an undercurrent.

In the fourth year of Yongle, the "Ba Zhi" of the Zhongshan Kingdom Sashiki captured the royal city of the Zhongshan Kingdom, Putian City, overthrew the rule of Wu Ning, the king of Zhongshan, and established his father Si Shao as the king, and established the first Shang dynasty.

Subsequently, "Ba Zhi" defeated the Beishan Kingdom in the 14th year of Yongle, and the Nanshan Kingdom in the 4th year of Xuandeok, unified the Ryukyu Island and moved the capital to Shuri Castle.

Emperor Xuande sent an envoy to canonize Ba Zhi as the king of the Ryukyus, giving him the surname "Shang", after which, the Zhongshan Kingdom was officially renamed the Ryukyu Kingdom, but Zhongshan is still used as another name for the Ryukyu Kingdom.

For example, in the official history books of the Ryukyu Kingdom, "Zhongshan Shijian" and "Zhongshan Shipu", "Zhongshan" refers to the "Ryukyu Kingdom". In the 21st year of the Kangxi reign of the Qing Dynasty, Emperor Kangxi gave King Shangzhen the plaque of "Zhongshan Shitu", and the "Zhongshan" here also refers to the "Ryukyu Kingdom".

Shangbazhi made the Ryukyu Kingdom prosperous, but after the death of Shangpazhi in the ninth year of Xuandeok, there was a civil strife in the Ryukyu Kingdom for the throne, Shuri Castle was almost completely destroyed, and the national strength of the Ryukyu Kingdom was weakened.

After the death of Shang Bazhi, the Ryukyu National Law Department wanted to make his son king, but was unanimously opposed by the ministers, and the princess of Shang Bazhi saw that the situation was not good, and fled with her son and was found and killed by the sergeants, and the ministers supported a person who had no blood relationship with the Shang clan as the king.

The tributary trade of the Ryukyu Kingdom to the Ming Dynasty was very developed, and the goods brought to the Ming Dynasty included gold and silver pots, gold and silver powder boxes, gold jars and wine seas, mud and gold color painting screens, mud gold fans, mud and silver fans, painting fans, banana cloth, ramie cloth, safflower, pepper, suma wood, waist knives, fire knives, guns, armor, horses, saddles, silk, cotton, and snail plates, and there was no fixed amount of additional tribute.

Even after the fall of the Ming Dynasty, the Ryukyus paid tribute again in the nineteenth year of the Kangxi reign of the Qing Dynasty, and the emperor ordered the exemption of some luxury goods, so in the later tribute, there were only horses and cooked sulfur, conch shells, red copper and other things.

The bulk of the Ryukyus' overseas trade was the sale of Japanese silver, lacquerware, swords, folding screens, and fans to the Ming Dynasty, the resale of medicinal herbs, porcelain, silk, and copper coins produced in China to Japan and Korea, and the sale of rhinoceros horn, sumac, spices, tin, sugar, ivory, frankincense, and ambergris from Southeast Asia, India, and the Arabian Peninsula to Japan, the Ming Dynasty, and Korea.

The Joseon Dynasty also developed entrepot trade from the Ryukyu to the South Seas, from which medicines, spices, and luxury goods such as pearls, tortoiseshell, and coral were imported. In Shurijo Castle (known as Haepo in Korea), the capital of the Ryukyu Kingdom, there were Ryukyu trading ships that sailed specifically to Korea.

Relations between the Ryukyus and Korea developed both politically and economically, but the role of the economy was greater than that of the government, as they both belonged to the vassals of the Ming Dynasty.
