In late October, Li Yuntian, Lei Ting and others left Seoul and rushed to Pyongyang Province in Xijing, Pyongyang Province, Pyongan Province, under the escort of the Korean army, to meet with Zhao De, who was sitting in Pyongyang City.

Zhao De originally thought that he would be very idle in Pyongyang City, but when the Ming fleet of goods arrived at the dock in Pyongyang Province, he was stunned to find that there were many things waiting for him to do, so he was so busy that he didn't even have time to eat every day, arranging the transportation and storage of military supplies.

When Li Yuntian entered the city of Pyongyang, he happened to encounter a convoy loaded with military supplies heading north to the Yongbyon Dadu Protectorate in Ping'an Province, which was only more than 100 miles away from the Yalu River, and across the river was the territory of the Ming Liaodong Metropolitan Division.

Before the heavy snow closed the road, Zhao De had to arrange as many people as possible to transport those military supplies to the Yongbian Dadu Protectorate for storage, so that they could be used as military supplies for the war with the remnants of the Northern Yuan Dynasty in the coming year, so Zhao De could be said to be shouldering a heavy responsibility this time, knowing that these military supplies were related to the success or failure of the war in Liaodong, he naturally did not dare to be sloppy in the slightest.

Due to the urgency of time, Li Yuntian did not stay in Pyongyang City for long, and two days later, under the escort of the 3,000 sergeants of the Suzaku Battalion of the Xiaowu Army, he rushed to Hamgyong Province, preparing to cross the Yalu River from North Hamgyong Province and go to the Nuer Gandu Division, which is across the river from the Korean Kingdom, and will meet the Jurchen tribes of the Nuer Gandu Division.

Li Yuntian knew very well that those recruits recruited from the Korean Kingdom needed at least half a year of rest, otherwise they would not be able to fight in the field with the Mongol soldiers of the remnants of the Northern Yuan Dynasty, so the Jurchen tribes of the Nuer Gandu Division naturally became the object of his vigorous wooing, and if he could get the support of the Jurchen tribes, then he would solve the trouble of insufficient troops.

Speaking of Hamgyong Province, there is one person who has to be mentioned, and that is the right of the North Korean National Assembly and the Hamgyong Province Soldier and Horse Festival Kim Jong-seo.

As the supreme commander of the six towns in the northeast of Hamgyong Province, Kim Zongrui sits in the Gyeongseong Metropolitan Protectorate in South Hamgyong Province, but Li Yuntian did not enter the city to see Jin Zongrui, and Jin Zongrui did not go out of the city to meet him, and he did not even have a person to say goodbye, which really surprised Li Yuntian, and also made him understand why Jin Zongrui was reused by the king of Joseon.

Li Yuntian is too lazy to deal with Jin Zongrui about the entanglement of etiquette now, since Jin Zongrui does not welcome him, then he will not be bored to cause trouble.

At the beginning of November, Li Yuntian crossed the Yalu River and entered the territory of the Jianzhou Jurchens of the Daming Nuer Gandu.

After the founding of the Ming Dynasty, it successively set up 25 guards of the Liaodong Capital Division and 384 guards of the Nuer Cadre Division to govern the northeastern region of the Ming Dynasty.

The Jurchens are distributed in a vast area east of the Songhua River, west of the lower reaches of the Heilongjiang River, east of the Sea of Japan, and south of the Korean Peninsula.

According to the distribution area of the Jurchen people, the Ming Dynasty divided the Jurchen people into three major ethnic groups, namely the Jianzhou Jurchen, the Haixi Jurchen and the East China Sea Jurchen.

Jianzhou Jurchen, with the original Bohai State Jianzhou as the name of the department, distributed between Changbai Mountain, Mudanjiang and Suifen River, with Hunchun County, Jilin Province, Ning'an County, Heilongjiang Province as the settlement, originally composed of the Jurchen Huo'er Abe and the Duo Lian Ministry, and the Tuowen Department moved south from the East China Sea during the Yongle period.

At the beginning of the Ming Dynasty, the chief of Huo'er Abe, Aha, was given the name Li Sicheng and served as the commander of Jianzhou Wei.

In the eighth year of Yongle, that is, in 1410 AD, after the death of Aha Chu, his son Shi Jianu was given the name Li Xianzhong and inherited his father's position. During the Xuande period, Li Manju, the grandson of Ahabout, lived as the hereditary commander of the Jianzhou Guard.

The chieftain of the Duoli Department was the fierce brother Timur, also known as Meng Temu, and Yongle served as the commander of the left guard of Jianzhou for ten years.

It is worth mentioning that while Emperor Yongle appointed Meng's brother Timur as the commander of Jianzhou Wei, he also set up Mao Lianwei, another Jurchen tribe of Huo'er Abe, in the north of the Tumen River and the Hunchun River valley, as the son of Jianzhou Wei.

Although Huo'er Abe was divided into two guards, the Ming Dynasty appointed the Jurchen leaders of Jianzhou Wei or Mao Lianwei to serve in the other party's Wei Division, so later history books said that those who lived in Jianzhou, Mao Lian and other places were Jianzhou Jurchens.

Haixi Jurchen, named because of its residence in the west of the East China Sea, is distributed in the lower reaches of the Songhua River in the area from Fuyu County, Jilin Province to Acheng County, Heilongjiang Province.

The name Haixi was first seen in the Yuan Dynasty and generally referred to the Jurchens of Haixi Zhuwei.

The Haixi Jurchens have four divisions: Hada, Huifa, Ula, and Yehe, and there are also Shanyi and Jiangyi.

Shanyi is a cave according to the mountain, that is, the mature girl is really perfect; Jiang Yi lives in Heilongjiang, that is, he gave birth to a Jurchen. Hada and Yehe belong to Shanyi, while Huifa and Ula belong to Jiangyi.

After the middle of the Ming Dynasty, the Haixi Jurchens moved to the Hulan River Valley, because Hulan and Hulun (Hulun) were transliterated, so the Haixi Jurchens were later called the Hulun Sibu.

The Jurchens of the East China Sea are a relatively backward part of the Jurchens, so they are also known as "savages" and are called "savage Jurchens", which are distributed on both sides of the middle and lower reaches of the Heilongjiang River and east of the Ussuri River.

The Jurchens in the East China Sea are divided into four divisions: Sakhalian, Hulha, Varkha, and Kurkha, and the Hulha is the hometown of the Jianzhou Jurchens.

The Jurchen people of the Ming Dynasty were regrouped ethnic groups, and the Jurchens of Jianzhou Wei and Mao Lianwei were mostly remnants of the Bohai people, engaged in farming and settled life, planting grains and spinning threads, and eating and drinking, which was not much different from the Han people.

Most of the Haixi Jurchens were descendants of the Wanyan tribe of the Jin Dynasty, and they were also engaged in farming, and they leaned on the mountains as villages, and their relatives lived together.

The Jurchens of the East China Sea, also known as the Savage Jurchens, are a branch of the Jurchen tribe that merged with the Hezhe and Oroqen tribes, and their customs are the same as those of the Haixi Jurchens, except that "they do not farm, but live by hunting".

At this time, Li Manzhu, the commander of Jianzhou Wei and the chief of Huo'er Abe, was forced to move the tribes of his tribe westward due to the attack of the Korean army, so as to avoid the Korean army, and not only lost the territory south of the Yalu River in Jianzhouwei, but also the land on the north bank of the Yalu River was also under the control of the Korean state.

Speaking of which, the Joseon state and the Jianzhou Wei and the Jianzhou Zuowei have a history of 30 years, when the Ming Dynasty set up the Jianzhou Wei, the Joseon king thought that the Ming Dynasty restrained its development to the north, so in order to resist the Jurchen return to the Ming Dynasty, the Qingyuan market trade was closed, which caused the Jurchens to resent.

Therefore, in the fourth year of Yongle, there was the "Gengyin Incident", and the Jianzhou Jurchens entered the territory of the Korean state to plunder and were repelled by the Korean army.

A few months later, due to the deterrence of the Korean army, the chief of Huo'er Abe, Ahachu, led his troops southwest to Fengzhou in the valley of the Huibo River (now Huifa River), along with some of Mao Lianwei's residents.

Meng's brother Timur led the Duo Lian tribe for generations to intermarry with Huo'er Abe, and the two tribes had a close relationship, so Meng's brother Timur participated in the "Gengyin Incident", fearing the retaliation of the Korean national army, Yu Yongle led his troops to move to Fengzhou in the ninth year, and lived in Qingshan City between Fengzhou and Kaiyuan City, an important military town in the north of Liaodong Dusi.

As a result, many of the territories of Jianzhou Wei and Jianzhou Zuowei fell into the hands of the Korean state and became the territory of the Hamgyong Province in the north of the Korean state, especially the Jianzhou Zuowei was all annexed, which made the Korean state control the middle and upper reaches of the Yalu River.

The military strength of the Korean state is more than ten times that of the Jianzhou Jurchens, and if the North Korean army pursues and attacks the Jianzhou Jurchens, the Jianzhou Jurchens will disappear.

However, because Fengzhou was protected by the Nuer Gandu Siming Army, the Korean State did not dare to launch an attack on the Jianzhou Jurchen Qingyi, which made the Jianzhou Jurchen Huo'er Abe and the Jianzhou Duo Lianbu get a rare opportunity to recuperate, and the economy and people's livelihood developed rapidly.

By the twenty-first year of Yongle, there were more than 10,000 households and a population of 70,000 or 80,000 people.

In the twentieth year of Yongle, in order to express his gratitude to the protection of the Ming Dynasty, the chief of the Duo Mercy Tribe, Mengge Timur, also led his troops to participate in the expedition of the Yongle Emperor to the Tatar Arutai Taishi, and made meritorious contributions in the war, and was summoned to Beijing by the Yongle Emperor to be rewarded.

The relationship between the Ming Dynasty and the Jianzhou Jurchens was in the honeymoon period during this period, and the fierce brother Timur was very obedient to the Ming Dynasty, and he personally went to Beijing several times during the Xuande period to pay tribute.

Li Yuntian crossed the Yalu River this time, the first goal was to find the fierce brother Timur, among the three major chieftains of the Jianzhou Jurchens, the fierce brother Timur was the most respectful to the Ming Dynasty, and at the same time, the territory occupied by the Korean state was also the most, so Li Yuntian naturally wanted to take the lead in winning over the fierce brother Timur.

In order to show that the Ming Dynasty attached great importance to the Jianzhou Jurchen, Li Yuntian naturally did not come empty-handed this time, in addition to the three thousand sergeants of the Suzaku Battalion of the Xiaowu Army who escorted him, there was also a baggage team accompanying him, which included both gold, silver, jewelry, silk, tea and salt, and excellent ordnance.

These burdens were a gift from Li Yuntian to the Jianzhou Jurchens, and he wanted the Jianzhou Jurchens to know that the Ming court had not forgotten them, so Emperor Xuande rewarded them with so much property.

On the third day after the Yalu River, Li Yuntian led the crowd to arrive at Qingshan City, and the fierce brother Timur had already received the news, so he led a group of officials from the left guard of Jianzhou out of the city to greet him.

Although Qingshan City is called "City", in Li Yuntian's view, it is just an earthen wall, surrounded by mud walls, and some low dwellings are made inside, because they are too simple, they cannot even be called "Earth City".

"The commander of the Jianzhou Left Guard sent Brother Meng's Timur to meet the envoy." Brother Meng Timur was burly, with a pigtail on his head, dressed in the costume of a Ming military attaché, bowed to Li Yuntian, who was riding on a horse, and bowed down to speak in a stiff Liaodong dialect.

If the name of the fierce brother Timur alone may feel very strange, I don't know who it is, but if it is mentioned by his other name, then many people's eyes will shine.

Mengge Timur, also known as Aixin Jueluo Mengtemu, is the ancestor of the founding emperor of the Manchu Qing Dynasty Nurhachi, two or three hundred years later the Manchu Qing Dynasty entered the customs to establish the Qing Dynasty, Mengge Timur was respected by the Qing court as the original emperor of the Qing Dynasty Zhaozu to be respected, is the ancestor of the Qing Dynasty.

Although he didn't know why Li Yuntian, as the deputy envoy sent by the Ming Dynasty to Korea, came to Nu'er Gandusi, but the due etiquette still had to be fulfilled, after all, it was rare for a Ming envoy with such a noble status to be seen in Nu'er Gandusi.

"Brother Meng's Timur commanded the envoy, this envoy heard about your brave deeds of following Emperor Taizong's northern expedition to Tatar as early as when he was in the capital, and today I saw that it was really extraordinary, no wonder he made great contributions during the northern expedition." Li Yuntian smiled and turned over and dismounted, and enthusiastically came to the front of the fierce brother Timur.

"The envoy is serious, and the lower official is just doing his duty."

Brother Meng Timur didn't expect Li Yuntian to be kind to him, he was slightly stunned at first and looked very surprised, you must know that those officials of the Ming Dynasty have always looked down on them as barbarians, and then they couldn't help but feel a burst of relief in their hearts, and they were very useful for Li Yuntian's compliment, and they invisibly had a good impression of Li Yuntian, and smiled sideways and made a gesture to Li Yuntian to please, "The lower officials have prepared wine and food for the envoy to pick up the wind and wash the dust, and the envoy please move into the city." ”

"Commander, please!" Li Yuntian smiled and stretched out his hand to humble, and then entered Qingshan City with his brother Timur chatting and laughing, and the atmosphere was extremely light.
