After Edmund Dantès sent a geological survey team led by Xu Xiake to Donggang Town, he took the "Zheng He" to Jeju Island to participate in the expedition and conquest of the area north of the Tsushima Strait by the East China Sea Patrol Office.

On March 26, the ship arrived at Jeju Port, the largest port in the northwest of Jeju Island, the only walled city on the island used by the Joseon Kingdom to exile criminals, and the center of Jeju Island's rule.

After Donggang sent people to take over Jeju Island, Liaodong refugees and some Donggang military dependents began to move to the city in large numbers, and by the time Edmond Dantès arrived, most of the Koreans in Jeju had been moved out of the city, and Liaodong people accounted for most of the city's population.

After the fall of the Yuan Dynasty and the annexation of Jeju Island to the Joseon Kingdom, the Koreans established Jeju Mu on Jeju Island, which consisted of two counties, Daejeong and Jeongui. However, North Korea is not a maritime country in the first place, and it does not attach importance to Jeju Island, which is far from the mainland.

Aside from the fact that the island, far from the mainland, was used as a natural prison, there were no large numbers of immigrants to develop it. Therefore, the population of the island is only more than 10,000 people, and the largest city on Jeju Island, Jeju City, has only 2 or 3,000 residents.

However, the Koreans established Jeju Township School, Jeongui Township School, and Daejeong Township School on the island, and a large proportion of the exiled criminals were political prisoners, that is, officials who had lost the political struggle.

As a result, the indigenous people of Jeju Island have almost assimilated into the North Koreans. The existence of these schools allowed Damyung to accept the jurisdiction of Jeju Island without much resistance.

However, after arriving on Jeju Island, the officers and soldiers of Donggang Town and the refugees from Liaodong forcibly occupied the land and houses of many large local officials, which aroused the resentment of many locals.

But after the New Year, the number of people who migrated from Dongjiang Town had exceeded 20,000, which was almost the total population of the island, and Dongjiang Town had always been on the front line of the war against Houjin, and those who survived had good military experience, and these immigrants had far more force than the local natives.

As a result, some large local families had to move from the more prosperous northeast of Jeju Island to the sparsely populated southwestern part of Jeju Island.

The southwestern part of the island, centered on Seogwipo Port, was a gathering point of population migration from the Ming Dynasty. Originally, it was just a small fishing village, but after the relocation of thousands of Ming people, it gradually revealed the rudiments of a city.

By the time Edmond Dantès arrived at the port of Jeju, the entire ruling order of Jeju Island had been basically established.

Originally, the Jeju Pastor of the Joseon Kingdom has now been changed to the Jeju Mansion of the Ming Dynasty. The two counties of Dajing and Jingyi have also been redivided into three counties: Chiayi, Renhe and Jinghai.

The officials of the Jeju Prefecture of Daming, who arrived in advance, abandoned the method of plundering the land and real estate of local residents by force in Dongjiang Town, and encircled some local officials and large households who were inclined to Daming.

In addition to selecting people from the immigrants to serve as prefectural and county officials, they also appointed a number of local large households to hold some official positions, alleviating the contradictions between the immigrants and the locals, and consolidating the ruling power of the Ming Dynasty on the island.

Chiayi County and Jeju Prefecture centered on the former Jeju Fortress, Inhwa County centered on Seogwipo, and Gyeonghae County centered on Seongsan became the new centers of Jeju Island's government.

However, Jeju Island, which had been agriculturally underdeveloped, suddenly fell into a shortage of food after its population doubled. Although the island has a large area of good pastures and abundant fishing resources near the sea, it is far from quenching the thirst of immigrants.

Therefore, when Edmond Dantès returned here, Jeju officials also asked him to bring a letter of reciprocation, in which they unanimously hoped that the immigration to Jeju Island would be temporarily suspended in order to ease the food pressure on the island.

On 1 April, 11 ships organized by the East China Sea Patrol Office and Edmond Dantès' "Zheng He" formed a large fleet of 12 ships.

On April 3, the fleet passed through the Tsushima Strait and spent two days repairing in Hagi City, a Mori family. As an experienced former colonial officer, Edmond Dantès did not shy away from interacting with the local Japanese.

After being imprisoned by the Japanese for half a year, he now has some understanding of the Japanese psyche. The local Japanese did not blindly welcome the arrival of the Ming fleet, but were still a little vigilant and wary under their enthusiasm.

Therefore, he believes that with the development of the area north of the Tsushima Strait by the Ming Dynasty, the Ming Dynasty and Japan may not be able to maintain the current friendly relations. Therefore, he suggested that after passing through the Tsushima Strait, ships needed a foothold that was under the full control of the Ming Dynasty, such as Wuling Island in the north of Korea.

The voyage from Wureungdo to Hagi City in Japan is only three days, and the voyage to Gangneung in North Korea is only one and a half days. The island's terrain is difficult and easy to defend, and the island has plenty of forest resources that can be used to build a harbor and repair ships.

Under the leadership of Huang Yongshu, who had been here last year, the fleet headed directly from Wuling Island to the Tumen River in the northeast, and did not go to the port of Wonsan in North Korea to the east.

Thus, on April 14, the fleet reached Mokora, where the Udiha were located. It was the first time that the Jurchens had seen such a large fleet arrive, and they thought that the Koreans wanted to attack them.

The Jurchens, who were on full alert, laid down their weapons and let them anchor outside the port of Mokowei after the leader Erjinai recognized Huang Yongshu.

The port built by the Jurchens was very rudimentary, allowing only two ships of more than 200 tons to barely dock, and other ships could only anchor in the bay.

When Uncle Huang Yong unloaded a batch of goods with his people, these Jurchens truly believed that they were here to trade and not for other purposes.

The chieftain Erjinai held a banquet in the village that night, entertaining several fleet commanders such as Zhao Chengdong and Huang Yongshu, and of course some commanders stayed on the ship to prevent accidents.

Because the Jurchens in the northeastern coastal area have always had contact with the Koreans, although they are not as civilized as the Jurchens in Jianzhou, they also have some basic etiquette.

However, these Jurchens also retained a large number of the customs of primitive clan society, such as the banquet where all the men and women of the village participated together, and no one stayed to guard the ships outside the port.

These Jurchens are simple and not very good at talking, but once they recognize the friendship of strangers, they will appear very enthusiastic. They speak and do things from their true feelings in their hearts, and all their emotions will be directly expressed on their faces and will not be hidden.

Because they are this kind of character, they don't like to associate with people who are hypocritical, and they like to associate with people who have a hearty and generous personality.

The Jurchens were very fond of the cotton, iron, boots, and arquebuses they brought with them, but the liquor they carried on board was the one they loved the most.

Because of the bitter cold in the north and the difficulty of conserving fresh water, the ship was equipped with a part of the wine to replace the fresh water reserve in case of emergency, according to European custom.

These drinks range from high-alcohol sugar cane liquor, to light ales made from barley, and some are highly alcoholic from sweet potatoes, which are used as medical supplies to disinfect trauma.

Because of the location in the northeastern coastal zone, in an area where the temperature is below zero for a small part of the year, alcoholic beverages have almost become a necessity of life. The Jurchens, both men and women, have a good amount of alcohol.

However, the backward agriculture and poor wine-making technology in the northeastern coastal area made the Jurchens rarely use grain to make wine. In addition to a low-alcohol drink made from birch sap, ginseng and fur are mainly used to exchange high-priced drinks with Koreans.

The Jurchens showed great interest in the drinks they brought. However, although the Jurchens were good at drinking, these Jurchens rarely developed the bad habit of alcoholism, which may also have something to do with their lack of living materials.

On the instinct of a former colonial officer, Edmond Dantès believed that the supply of cheap and inferior liquor to the northeastern coastal region should be increased. Taking advantage of the abundant material supply of the Ming Dynasty, he destroyed the local daily life and customs, so that these Jurchens were used by the Ming Dynasty.

These Jurchens were industrious and frugal, and if they only established ordinary trade with them, it would only increase the power of this tribe, which was not a good thing for the Ming Dynasty.

But if they can destroy their simple nature with alcohol, then these Jurchens will become the most loyal mercenaries of the Ming Dynasty. A nation addicted to alcohol will not be able to form a unified emerging power.

Edmond Dantès stayed at Mokover until 25 April, after which the fleet headed for Vladivostok in the north with more than 200 Jurchens hired from there.

Prepare to build a city and establish a foothold in this area. The hired Jurchens cost the fleet only 20 barrels of wine, while the hired Jurchens received a ration and a set of iron tools.

After seeing this huge fleet and the abundant materials transported, the Jurchens in the area finally had a vague idea of the richness of the Ming Dynasty. At the invitation of Zhao Chengdong, a Jurchen leader also boarded the ship and witnessed an artillery exercise.

Under this combination of grace and power, the Jurchens of Mokowei finally expressed their willingness to surrender to the Ming Dynasty and pay a number of tributes such as mink, ginseng, and mountain mushrooms to the Ming Dynasty every year.

In addition to handing over his second son to Zhao Chengdong, the leader Erjinai also expressed his willingness to contact the six inland Varkha tribes for the Ming Dynasty and form an alliance with the Ming to resist the Houjin.

Zhao Chengdong, the warden of Vladivostok, who was in charge of the conquest of the northeastern coastal region, was so pleased with Erjinai's deference that he immediately presented 10 pairs of armor and 20 arquebuses, 2 barrels*, and 1,000 rounds of guns.

In addition to promising that after the covenant was reached, he would give more remuneration to the Mokowei Ministry, and also appointed Erjinai as the hundred households of the Ming Mokowei.
