After leaving Yang Yungui's house, Li Yuntian went straight to the Jiangwu Hall, because the Jiangwu Hall was under militarized management, so the officials were concentrated in the dormitory provided by the Jiangwu Hall, Li Yuntian quickly gathered several military attachés in charge of the Jiangwu Tang Government Affairs Hall, and arranged for them to receive the fifty percent of the property allocated by the household department.

Among them, the most important thing was naturally the movement of the 5 million taels of property used as military funds, which would be secretly transported to the port of Tianjin according to Li Yuntian's request, and then loaded onto the sea ships parked there, and then transported to the Korean state.

Since the situation in Liaodong was responsible, for the sake of safety, Li Yuntian was prepared to place those belongings in the territory of the Korean state, so as not to be coveted by others, and then cause any incidents.

After explaining the affairs of the military attachés of the government affairs hall, it was late at night, Li Yuntian went to bed in a side room of the martial arts hall, Lei Ting carefully brought him water to wash his face and feet, and waited for him to untie his clothes, if it were not for Lei Ting to take care of him all these years, Li Yuntian's life would definitely be a mess.

Therefore, Li Yuntian has a special affection for Lei Ting, the two have not only lived and died together, but also spent the longest time together, so the relationship is naturally deep.

"Xianggong, this time the three guards of Wuliang Ha are menacing, and there are Tatars and even Warats to help, plus there are people planning behind the scenes, the war situation in Liaodong is not optimistic."

After some warmth, Lei Ting lay in Li Yuntian's arms and stroked his cheek worriedly, although the Northern Yuan Dynasty has been dispersed into three major tribes, it is difficult to show the majesty of the Mengyuan Empire back then, a single tribe is not terrible, and it is difficult for a single person to become a climate, but if the three are deliberately united, it will be a powerful force that cannot be ignored.

In particular, Zhang Hao and Liang Kun were unexpectedly defeated one after another, which was enough to show that the other party had made sufficient preparations for the Ming army's conquest, which made Lei Ting feel uneasy.

"The soldiers will block, the water will cover the earth, the national strength of the Ming Dynasty is at least ten times that of these remnants of the Northern Yuan, they may be able to win for a while, but the final winner must be my Daming." Li Yuntian smiled disapprerovingly, reached out and hugged Lei Ting tightly, and comforted him softly.

"Xianggong, are you worried that the people of the Northern Yuan Dynasty have gone to Korea?" Lei Ting immediately smiled when she heard this, in her impression, Li Yuntian had never flinched when she encountered difficulties, and then remembered one thing, and couldn't help asking.

"If Xianggong is a person from the Northern Yuan, in order to make the war situation in Liaodong favorable to them, then he will definitely appease and win over the king of Joseon." Li Yuntian bowed slightly, and explained to Lei Ting with a smile, "Xianggong went to Korea this time not only to find out the truth of the King of Joseon, but also to set up a military affairs office there. ”

"Xianggong, the concubine heard that the weather in Korea is cold, poor and barbaric, and the palace of the king of Korea is not even as luxurious as the mansion of the southern merchants, why do you attach so much importance to it?"

Lei Ting's eyes suddenly showed a suspicious look when she heard this, it was already very abnormal to let Li Yuntian go to North Korea in person, and now Li Yuntian actually wanted to set up a martial arts hall office there, which really made her a little puzzling, in her opinion, there was nothing worth Li Yuntian's attention in North Korea.

Although it seems that the Jiangwutang Office is only a subordinate yamen in charge of the local affairs of the Jiangwutang, if it is set up in the Korean State, it will undoubtedly assume the responsibility of collecting intelligence and co-opting the officials of the Korean State.

"The DPRK and our Ming Dynasty have a long history, but in recent years, there has been constant friction on the border with our Ming Dynasty, and the establishment of the Jiangwutang Office can also avoid a greater conflict between the two sides." Li Yuntian smiled when he heard this, and looked at Lei Ting meaningfully.

Lei Ting saw Li Yuntian's high-sounding tone, and immediately laughed out loud, she had been with Li Yuntian for so long, and naturally knew that what Li Yuntian said was just a cover, and it seemed that Li Yuntian wanted to strengthen his control over North Korea.

The next day, Li Yuntian quietly left the capital, and rode straight to Tianjin Wei, where he had already handed over the more than 10,000 soldiers of the Suzaku Army to reinforce Liaodong under the command of Li Daniu, who would lead those soldiers from Tianjin Port to Liaokou Port of Gaizhouwei on the Liaodong Peninsula, where they landed and galloped to the Ming army in Liaoyang City.

Li Yuntian, on the other hand, took a boat from Tianjin Port to Incheon Port, west of Seoul Prefecture, to inquire about news and arrange follow-up matters.

On the carriage to Tianjinwei, Li Yuntian took a piece of information related to the Korean state in his hand and looked at it slowly, which Yang Yungui had sorted out and sent overnight, and listed the territory and political system of the Korean state.

The state of Korea divides the territory of the country into eight provinces, commonly known as the eight provinces of Korea, namely:

Gyeonggi-do: Including Seoul and Kaesong, the capital is in Seoul.

Gyeongsang-do: including Gyeongju Mansion, Sangju Pasture, and Jinju Pasture, with the left barracks, right barracks, left water barracks, and right water barracks, and the capital is in Gyeongju Province.

Jeolla Province: Including Jeonju Pastoral Camp and Naju Pastoral Household, with barracks, left water camp, and right water camp, and the capital is in Jeonju.

Chungcheong-do: including Chungju pastor, Cheongju pastor, Gongju pastor, set up water camp, the capital is in Cheongju.

Huanghai Road: including Huangzhou Mu and Haizhou Mu, the capital is in Huangzhou.

Pyongan Province: Including Pyongyang Province, Yongbyon Dadu Protectorate, and Uiju Mu, the capital is in Pyongyang Province.

Gangwon Province: Including Gangneung Metropolitan Protectorate and Wonju Mu, the capital is in Gangneung.

Hamgyong Province (Ning'an Road): Including Hamxing Province, Gyeongseong Metropolitan Protectorate, and Northern Qing Metropolitan Protectorate, the capital is in Hamhung Province.

The province of Korea is equivalent to the provincial-level local body of the Ming Dynasty, with prefectures, prefectures, counties, and counties under it.

Among them, the five provinces of Gyeongsang, Jeolla, Chungcheong, Hwanghae, and Gyeonggi were later divided into two provinces, the left and right, the Nyeongan Province (Hamgyong Province) was divided into two provinces, the North and South provinces, the Pyongan Province was divided into the East and West provinces, and the Gangwon Province was divided into two parts: Yeongdong and Yeongseo.

In addition to this division of local administration, ancient Korea also traditionally divided the country into six regions, namely:

Kanbuk (Hamgyong Province, Pyongan Province); Kansai (Hwanghae-do, southern Pyongan Province, and western Gangwon-do); Kanto (the part east of Taebaeksan, Gangwon-do, also known as Yeongdong); Gihu Lake (all of Gyeonggi-do and part of Chungcheong-do); Hunan (part of Chungcheong-do plus Jeolla-do); Yeongnam (Gyeongsang-do)

It is worth mentioning that in the early years of the Joseon Kingdom, the area around Hamgyeong-do and Pyongan Province in the northern part of the Korean kingdom was not inhabited by Koreans, but was an area where the Jurchens lived.

During the 400 years of the Liao, Jin, and Yuan dynasties, the northern border between the three dynasties and the Goryeo Kingdom, the predecessor of the Joseon Kingdom, was basically stable in the Yongxing region of Gangwon Province, the Joseon Kingdom.

After the establishment of the Ming Dynasty, the northern part of the Korean State was governed by the Tielingwei established by Ming Taizu, and the Tielingwei retreated north after Yongle of the Ming Dynasty, so that the king of Korea took advantage of the situation to send troops into this land.

At that time, the area around Hamgyeong-do and Pyongan Province was inhabited mainly by Jurchens, and the Jurchen tribes formed the northern barrier of Korea.

During the reign of King Sejong of the Joseon Kingdom, the Joseon State forcibly relocated Koreans from the south to settle in the northern region, and gradually implemented effective control over the northern region.

According to the Records of Sejong of the Yi Dynasty, the migrated Koreans were not adapted to the climate in the north, and the epidemic was epidemic, so that "the new migrants were uneasy and wanted to return to their homeland, or die."

In order to ensure the stability and security of the northern region, the Joseon king had to deal with the relations with the local Jurchen tribes, and in order to control the Jurchens, he took two measures, restraint and military conquest, to ensure effective control of this region.

The Joseon king's strategy of restraint against the Jurchens was first of all to show grace and envelop them, giving the chiefs the positions of guards and generals, and at the same time, in case of natural disasters for the Jurchens, they would also provide relief.

Since the Joseon Kingdom Taizong began to show favor to the Jurchens, according to the "Records of the Emperor of the Li Dynasty", the Mengge brother of the Jianzhou Wei chief at that time asked to see, that is, with his "dwelling in my realm, for my fence, it is appropriate to treat it thickly".

During the reign of Sejong of the Joseon Kingdom, the Jurchen chieftains were given the title of guard. "The Records of Shizong of the Li Dynasty" recorded: "Yu Yidi of the Chinese Dynasty, who did not hesitate to remove those below the rank of governor, did not want to guard, but also wanted to be restrained." At the beginning of the country, Wanhu Xuanluo was a general, and he did not hesitate to grant it remotely, but also wanted to be restrained. ”

Not only did he grant official positions to the children of the officials of Jianzhou at that time, but also ordered him to marry a wife in Korea, so that he could serve the guards with peace of mind, "so that he could go back and forth to visit his relatives, then he would have his own heart of permanent peace."

During the reign of King Sejong of the Joseon Kingdom, there was a rare drought in the left, middle, and right three guards of Jianzhou, and the grain and food were all dried up, so the Joseon State gave grain, and people gave two liters of rice and one liter of salt to relieve the famine, which made the Jurchen tribes grateful, and this was a cohesive measure.

The relationship between the Korean kingdom and the Jurchens was good and bad, and when the relationship was good, they lived in peace and traded with each other, and when the relationship was bad, they inflicted wars.

When the Jurchens were unable to trade with the Korean Kingdom, they often looted goods on the border of the Korean Kingdom to make ends meet, and the Korean Kingdom sent troops to attack, so the war continued.

Since the Joseon kingdom was always in a dominant position in its long-term dealings with the Jurchens, it had the strength to control the Jurchens, while the Jurchens were in a scattered and passive situation. This long-term unequal status has created a cultural mentality that despises the Jurchen in Korea, and has been deeply branded with the concept of the Jurchen as "Yidi".

"Four counties and six towns!" After reading the information provided by Yang Yungui, Li Yuntian's brows couldn't help frowning slightly, and his expression became stern.

After Sejong of Joseon succeeded to the throne, he sent Kim Jong-seo, a general from Jinshi, to serve as an observer envoy to Wanghamgyong Province in the northern part of Joseon to open up six towns in the northern frontier to ensure the security of the northern part of Joseon.

At that time, the Korean court had mixed reviews of Kim Jong-seo's trip, fearing that this move would anger the Ming Dynasty, but Kim Jong-seo "strongly advocated his own affairs", but fortunately Sejong approved and was able to succeed.

Hamgyong Province was the territory of the Jurchen Udiha tribe at that time, and Kim Jong Seo Shun defeated the Udiha tribe, revoked the Jianzhou Left Guard established by the Ming Dynasty, and established the six towns of Hoeryeong, Wenseong, Zhongcheng, Gyeongwon, Gyeongheung, and Maoshan in Hamgyong Province.

Subsequently, Sejong of the Joseon Kingdom took tough measures against the Jurchen tribes in the northern part of the Korean state, conquering a large area of land that originally belonged to the Jurchen tribes of the Ming Dynasty in the northern and northeastern frontier areas, and then obtained the land of the Jurchens in the northeast of the Korean Peninsula, completely resolving the territorial dispute of Baozhou (Liao Dynasty) left over from the war between the Liao State and Goryeo, and the territory exceeded the unified Silla era and the heyday of Goryeo.

In order to stabilize the northern border, Sejong of Joseon set up four counties in the north of Pyongan Province, which is adjacent to the Liaodong Metropolitan Division of the Ming Dynasty.

However, because the Jurchens in the northeast of the Korean Peninsula were under the jurisdiction of the Ming Nuer Gandu Division and the Liaodong Capital Division, this move of the Korean State was undoubtedly an invasion of the territory of the Ming Dynasty, so although envoys were sent to Beijing many times to ask Emperor Yongle and Emperor Xuande for the territory east of Tielingwei and the territory of Jianzhou Zuowei, the Ming Dynasty never agreed.

Due to the remoteness of the Korean State and the subject state of the Ming Dynasty, the hundred officials of the Ming Dynasty did not pay attention to this matter, and the matter dragged on, so that the Korean State was later able to border the Yalu River and the Douman River with the Ming Dynasty.

King Yi Geun of Joseon used Kim Jong-seo to defend the six towns of Hamgyong Province and Choi Yeon-deok to defend the four counties of Pyongan Province, and often clashed with the Jurchen tribes who were unwilling to be driven away.
