In East Asia, because for thousands of years, China has occupied the most elite region, and the four directions of the southeast, northwest, and northwest are either grasslands and deserts, or lofty mountains, or simply the sea, so those dynasties of the Central Plains often did not have much interest in the territory of the surrounding vassals, so they formed a unique tributary system.

Due to the rich land of the Central Plains and the low demand for trade in the feudal era, the Central Plains Dynasty did not like to use force to coerce and submit and establish colonies to squeeze the surrounding countries like the West, forming a hierarchical network political order system with the Central Plains Empire as the main core, which lasted for more than 2,000 years.

After the establishment of the Ming Dynasty, Zhu Yuanzhang, the Taizu of the Ming Dynasty, clearly stipulated that Annam, Champong, Chenla, Goryeo, Siam, Ryukyu, Sumatra, Java, Huheng, Baihua, Sanfuqi, Boni and other Western and Nanyang countries were "non-conscripted countries", which actually established the actual control scope of China; He also established the tributary principle of "thick and thin"; Thus the tributary system was finally established, which became the prevailing system of international relations in the Eastern world; In this system, the Central Plains regime of China became the center of the unitary power, and the tributary states recognized this central position and constituted the outer vassals of the central power.

Under the influence of the tributary system, the East Asian region gradually formed an East Asian cultural circle with Chinese characters and Confucianism as the core, and those vassal states did not need to worry too much about the attack of the Central Plains Dynasty on them, but only needed to pay tribute to them according to the requirements of the Central Plains Dynasty, so as to maintain peace between the two countries and get rewards several times that of tribute; And the Central Plains Dynasty did not have to bear the high military expenses of the vassal states, which seemed to be very beneficial to both sides at first glance.

Therefore, the envoys of the Li Dynasty thought that as long as they sincerely pleaded with the Ming as before, they could be forgiven by the Ming Dynasty, and they could not bear some reprimands, and then they could continue to shrink into their own small land and live the same life as they had for hundreds of years before, but the words of the officials of the Ministry of Rites shattered his illusions and made him panic.

"What Lord Shangguo said is the compensation for land cession? This... I'm afraid this can't be done! The messenger who woke up from the shock thought that he had misheard, and after receiving a definite answer, he hurriedly brought out many Confucian classics, saying that the Central Plains was a country of generosity and mercy, how could he treat his subjects so harshly?

In fact, the officials of the Ministry of Rites also have a general idea in their hearts, in their opinion, the Ming Dynasty is rich and has everything, how can they look down on the barren land of North Korea? However, Li You understood that this tributary system established under the feudal system would soon be out of line with the development of the times, and if the Ming Dynasty wanted to still occupy the position of the world's first-class power for hundreds of years, it would have to change this ancient policy.

Daming's goods need markets, Daming's factories need raw materials, and Daming's army needs suitable military bases, all of which cannot be done by the tributary system that has lasted for thousands of years, and North Korea's rash action provides a suitable excuse for change, how can he not hold it tightly in his hands.

"Since you know that you are a vassal country, why do you dare to invade my Ming territory! Tens of thousands of Korean soldiers brazenly invaded the territory of my name, killed our Ming people, and looted property. The Ministry of Rites Shangshu reprimanded, although he didn't understand, but he still had to complete the task assigned by His Majesty the Emperor.

"Those... Those people who are by no means the Ming Dynasty are slaves. The Korean envoy trembled and said, "We also want to do our best for the kingdom, and we will return to the country when we solve the problem of Jiannu, and we have no other ideas!" ”

"Humph! Although Jiannu is a rebel, he is also a member of my Ming Dynasty. The Ministry of Rites Shangshu quickly seized the loophole in this person's words, although Jiannu had been founded, but it had never been recognized by the Ming Dynasty, and they had always regarded it as a rebellion in the country rather than an enemy country, "Do you say this to have recognized Jiannu as an enemy country?" ”

"Don't dare, I won't dare." Although they all think so in their hearts, they never dare to admit it; However, under the pressure of the Ministry of Rites, the North Korean envoy had to back down step by step, and the Ministry of Rites Shangshu vaguely mentioned a few words about the legitimacy of Li Liang's succession, so he didn't dare to say much, and began to put away his luck and ask about the plans of the Ming Dynasty, wanting to see what kind of conditions they would offer.

"Ceded Jeju Island to the Ming Dynasty for horse breeding and as a transit point for caravans going to sea." The conditions of the Ming Dynasty are quite generous, and they did not covet the core land of North Korea, but just claimed a desert island in North Korea, and the status of Jeju Island in North Korea is not important now, and there are no great nobles, so the envoy relaxed a little, maybe it is not unacceptable to use such a desert island in exchange for the forgiveness of the Ming Emperor to North Korea.

Of course, the Ministry of Rites Shangshu said that it was used as a transit station for the Ming caravan, but in fact, Li You planned to build Jeju Island into an important base for the Ming Navy Division in the north, and use it as a springboard to deal with the Japanese State in the future.

Jeju Island is strategically located close to both Korea and Wakoku, has a natural harbor that can accommodate a strong sailor, and the island's fertile soil is ideal for farming and horse breeding.

The envoy sent Daming's request back to China, and after several back and forth, Li Liang and the civil and military officials of North Korea saw that Daming was resolute, and Jeju Island seemed to be no big deal in their eyes, so they had to agree to Daming's conditions, ceding Jeju Island to Daming, and then spent a lot of money to ransom those captured officers, as for those ordinary soldiers, no one cared about them at all, and they would be sent to Liuqiu Island by Daming to contribute to the development of Liuqiu.

After the treaty was signed, Yu Zhigao immediately led his fleet to occupy Jeju Island and expelled the Korean officials who remained on the island, but the people did not react much, and it seemed to be the same thing to them anyway.

A shipload of craftsmen also set out from Jinmun and soon arrived on Jeju Island, where they began to build the port with the help of sailors; In addition, the Jeju prefect and the Jeju general army appointed by the imperial court also took office with their subordinates, and established a new ruling system on Jeju Island. In addition, Jin Yiwei gradually blended into the merchant ships bound for the Wa Kingdom, and began to inquire about the information of the Wa Kingdom, and His Majesty the Emperor was very concerned about the Wa Kingdom.
