The treatment of Mongolia could not be like the Jiannu either killed or taken captive to other places for hard labor, because most of the land they occupied was not suitable for arable land, and it was difficult to attract immigrants from the Guannei to fill it, even if they were all moved, there would still be barbarians from other places to occupy the land they left behind and continue to harass the border towns of the Ming Dynasty; Second, today's Mongolian cavalry has long since lost the strength of Genghis Khan, and the tribes are constantly fighting each other, and they have long been scattered. Pen ~ fun ~ Pavilion www.biquge.info, they don't have the ability to cause much trouble to Daming.

Therefore, Li You's plan was to use military, economic, political and other means to strengthen the rule of the desert, first build cities in various strategic places, build castles to garrison, and then expand the surrounding tuntian to save expenses, and use military force to suppress the tribes so that they dare not resist, while maintaining the smooth flow of trade routes and the safety of merchants.

At the same time, various agricultural and animal husbandry product processing workshops were built in several cities near the desert to process the wool, mutton, cowhide, beef and other materials abundant on the grassland into best-selling products and sell them to various places, and to control the grassland by economic means; Then set up trading houses on the periphery of the castles to purchase the output of the Mongols, sell their daily needs of tea, salt and other goods, bundle their daily life with the smooth flow of trade routes, and incorporate the Mongolian steppes into the economic circle of the Ming Dynasty, and when all the people here have to rely on the trade with the Central Plains in exchange for the goods they need, they can no longer get rid of the control of the Ming Dynasty.

Of course, Li You will also set up a school outside the castle, the official yamen, and the school is used to teach the children of those tribal nobles, if they do not complete their studies in the future, they will not be qualified to inherit the status of their father and brother, and then use the superiority of Ming culture to slowly assimilate them; The government was used to maintain order in the local area, slowly competing for power with the tribal nobles, and eventually turning these places into the direct jurisdiction of the Ming government.

In addition, Li You also planned to introduce the religion of the Central Plains to compete with Tantra and shamanism for believers, so he would also build some temples and Taoist temples around the castle, so that those monks and Taoists could use this as a basis to attract a wide range of believers.

After gradually leveling the remnants of Lin Dan Khan's forces, Li You began to assign tasks, he divided the steppe he had just laid into several capital protectorates, and let young generals such as Cao Bianjiao, Li Zicheng, and Zhang Xianzhong act as capital protectors, and redivided the sphere of influence on the Mongolian steppe, the land near the castle and the fertile pastures were assigned to those tribes who were on the verge of rebellion, and the farther and more general pastures were divided into tribes that quickly surrendered, and the few tribes that resisted stubbornly could only be assigned to the most barren pastures, Perhaps it will be a long time before they are completely annexed by other tribes.

Although most of the captives were released, Lin Dan Khan's cronies could not be easily forgiven, these people will be responsible for the Mongolian steppe to the Central Plains, as well as the construction of various castles, the Ming Dynasty had accumulated rich experience in the process of building the Ningjin defense line, plus Li You integrated into the advantages of the Western Fortress, and after the castle was repaired, only thousands of soldiers and horses were needed to garrison, and the vast land could be firmly controlled.

After arranging these things, the eastern part of the Mongolian steppe was left to Cao Bianjiao, Li Zicheng and others to deal with, and Li You led Lu Xiangsheng, Cao Wenzhao, Man Gui and others to continue to attack the west.

Oirat Mongol Yuan Dynasty is called Woo Yi Rati, to the Ming Dynasty is called Warat, because it has a hereditary marriage relationship with the Genghis Khan family, so it enjoys a special status in the Mongolian tribes, in the process of Zhu Yuanzhang raising troops to overthrow the Mongol Yuan, Oirat Mongolia gradually grew in strength, and constantly annexed other tribes.

By the time of Ming Chengzu Zhu Di, he had defeated the Oirat Mongols in the imperial expedition, and the leader of the Oirat Mongols, Tuhuan, accepted the title of the imperial court and called the king of Shunning; When Tuhuan's son also succeeded to the throne first, Oirat Mongolia developed to its peak, controlling the eastern Mongolian tribes, and on the other hand, it used military conquest, official vows, marriage alliances and other means to put Qierjisi, Hami, Shazhou, Handong, Chijin, and Wuliangha Sanwei under his rule, and befriended the Jurchen tribes to make them work for them.

And launched a large-scale attack on the Ming Dynasty, Ming Yingzong under the instigation of the eunuch Wang Zhen to drive the expedition, but also first lured the Ming army to Datong, breaking its vanguard. Immediately afterwards, he gathered troops at Tumu Fort, annihilated the main force of the Ming army, and captured Ming Yingzong; After this battle, the vitality of the Ming Dynasty was greatly damaged, but Yu Qian also brought heavy losses to Yexian in the capital.

Subsequently, there was a split within the Oirat Mongols, and a fierce war broke out with Tokhtobuhua first; Tokhtobu and his younger brother Agadolji joined forces, and their strength was roughly equal to each other, and it was difficult to distinguish between victory and defeat. Later, due to the infighting between the brothers, Agadorji also defected first. Tokhtar did not lose strength and fled to Uliangha, and the Oirat Mongols gradually declined.

After that, Dayan Khan arose, the eastern Mongolia gradually overwhelmed the western Mongolia, and now the Oirat Mongolia is divided into four divisions: Dzungar, Heshute, Dulbert, and Turgot, the Dzungar department strongly controls the north and south of the Tianshan Mountains, the Turghut department moves west to the banks of the Volga River, the Heshute department moves to Qinghai under the leadership of Gushi Khan, and the Dulbert department is nomadic in the area of the Kobdo Altai Mountains.

In other words, the Oirat Mongols now happen to occupy the jurisdiction of the former Tang Anxi Protectorate, due to the important geographical location of this land, as well as the threat of Geldan to the Central Plains in the future, Li You cannot let them go free.

The strength of these two tribes is much weaker than that of Lin Dan Khan's coalition army, and after Li You left half of his men to defend eastern Mongolia, the remaining troops are still more than enough to solve them, but the complex climate and dangerous roads in Qinghai and the Western Regions have caused them more trouble.

However, Li You is very familiar with the terrain and climate here, and commanded this army to avoid many natural disasters without danger, successfully found the main force of the Dzungar Department and the Heshuo Special Department, and defeated it, took back the Central Plains' dominance over Qinghai and the Western Regions, and re-established the Anxi Metropolitan Protectorate and the Beiting Metropolitan Protectorate, and guarded this place with Cao Wenzhao and Chen Jisheng.
