While planning the political and economic changes of the imperial court, Zhu Youxiao also paid attention to the situation in various parts of the country. In the northwest region, Yuan Yingtai has officially served as the governor of Shaanxi and Gansu, and the area under his jurisdiction includes Shaanxi, Gansu, Ningxia, and northern Qinghai.

After more than half a year of training, the Ming Dynasty army in the inner set has expanded to more than 50,000 people, Yuan Chonghuan is worthy of being a master of military training, just like in history he trained the Guanning iron cavalry, here Yuan Chonghuan has trained the Hetao light cavalry. However, the Hetao light cavalry trained this time is different from the historical Guanning iron cavalry, the Guanning iron cavalry is mainly based on breakthroughs, for ordinary cavalry and infantry, once the defense line is broken, there will be a sense of inner fear, even if the female * cavalry is also afraid of being broken through the middle line of defense. The Hetao light cavalry was about speed and persistence, which were originally very contradictory abilities, for example, the Mongol cavalry often rested their horsepower before charging in order to charge quickly, and one man and two horses remained long-lasting. In order to maintain these two abilities, Yuan Chonghuan adopted one person and three horses, and the soldiers were no longer equipped with armor, only helmets, and the other was to equip a steel plate on the outside of the left forearm, and groove in the middle of the steel plate, set up a small arm crossbow, set up five crossbow arrows, the saber is made of the latest development of good steel, is Zhu Youxiao in accordance with the design of the "Xuefeng knife" developed, light, stable center of gravity, fast knife edge.

These equipment cost Xu Guangqi, Song Yingxing, Bi Maokang and others a huge amount of energy, although the idea was Zhu Youxiao, but the specific development, manufacturing, and testing were indeed completed by a few of them, for which Zhu Youxiao each gave them a share of the original shares of Tenglong Bank, which moved the three of them to tears, this is the greatest grace, that is, Sun Chengzong such a core figure does not have this kind of grace. In fact, Zhu Youxiao wants to completely take these scientific bulls into his chariot, and Zhu Ling and Lei Zhentian also have one share each. Of course, these shares are Zhu Youxiao's own, not from the vassal kings, so as not to displease them.

Because the cost of these equipment was quite high, Zhu Youxiao only asked Yuan Chonghuan to form a 10,000-man Hetao light cavalry, and also equipped this Hetao light cavalry with a light artillery unit of 5,000 people, which was mainly for fire support and battlefield isolation strikes, with the purpose of destroying the enemy's will to resist and reduce the battlefield losses of the Hetao light cavalry. The actual commander of this Hetao light cavalry is Lu Xiangsheng, because Zhu Youxiao is very optimistic about Lu Xiangsheng's ability, he is still a little worried about Yuan Chonghuan's character, afraid that he is too selfish and causes jealousy. In order to further protect Lu Xiangsheng, Zhu Youxiao also asked Li Hongji, Liu Zongmin, and Li Guo to serve as the hundred generals of this army respectively, so that these three future generals would listen to Lu Xiangsheng's orders and become Lu Xiangsheng's generals.

As for Sun Yuanhua and Hong Chengchou, their tasks are also very heavy, and they command musketeers and artillery corps, mainly infantry, which are mainly used for storming fortifications and positional warfare. For this reason, Zhu Youxiao specially appointed Sun Yuanhua as the chief military officer and Hong Chengchou as the adjutant, which is also Zhu Youxiao afraid that Hong Chengchou would be captured by the enemy in case of capture, and then resort to the beauty trick, and take this old boy to his heart, Zhu Youxiao can lose a general in vain, so let Sun Yuanhua be the chief officer of the army, and Hong Chengchou is in command on the front line when the specific battle is carried out. In short, this is called employing people who are suspicious, and suspecting people also use, taking their strengths and discarding their shortcomings.

When it comes to a campaign or war, Yuan Chonghuan is responsible for the overall planning, Sun Yuanhua, Lu Xiangsheng, and Hong Chengchou's suggestions provide reference, and finally Yuan Chonghuan and Sun Yuanhua jointly sign and implement the battle plan. As for the tactical arrangement of each battle, Yuan Chonghuan was no longer specifically responsible, Lu Xiangsheng organized the battle by Lu Xiangsheng himself, and Sun Yuanhua and Hong Chengchou's troops were jointly formulated by the two.

Su Nang Taiji has been released from the capital, followed by a large number of military supplies, Zhu Youxiao is very relieved to bring these materials back from Su Nang Taiji, because Su Nang Taiji has been completely frightened by the powerful military power of the Ming Dynasty. Altan Khan returned to Dongshengcheng, gathered all the Mongol tribes in the inner sleeve of the Yellow River, and conveyed to them the will of the Ming court, asking everyone to completely change their original living habits, live like the people of the Ming Dynasty, fully integrate into the Ming Dynasty, and become an inseparable part of the Ming Dynasty.

The preparations have been very sufficient, Yuan Chonghuan informed Yuan Yingtai to prepare the logistics work, he will lead more than 50,000 people to recover the entire Hetao area, will be in accordance with the emperor's will, the entire Hetao area will be included in the territory of the Ming Dynasty, this place will be transformed into a stable rear, in order to subdue the entire desert north and further places in the longer future to do a good job of material and population base. This is what Zhu Youxiao said in private, so Yuan Chonghuan didn't dare to talk nonsense to others, but he admired Zhu Youxiao even more in his heart.

The composition of the Mongolian Tumut tribe in the Hetao area is very complex, which has a lot to do with the nomadic life of the Mongols, the Tumut tribe is a nomadic tribe composed of many 10,000 households, in the last century when Altan Khan was the leader, it is a powerful tribal group, the territory extends to the Chahar tribe in the east, Xinjiang, Qinghai, Tibet have their traces, even the title of the third * Lama is given by Altan Khan. However, after the death of Altan Khan, the power of his descendants continued to weaken due to the fact that his descendants fought against each other for the throne, and the current territory was limited to the Hetao area and the surrounding areas.

Altan Khan's wife, Sanniangzi, has been married to three generations of Great Khans, and the current Sunang Taiji is her grandson, while Bushitu Taiji, who occupies the Khan throne in Guihua City, is the grandson of Altan Khan's ex-wife. Originally, the third lady wanted to pass on the Khan position to Sunang Taiji, but was opposed by the Ming Dynasty and other ten thousand households, so he had no choice but to hand over the Khan position to Bu Shitu Taiji, and since then he has also lost his power and died soon after. Su Nang Taiji and Bu Shi Tu Taiji failed to compete for the Khan throne and lost the rule of half of Daban City, but under the Zhao Buddha of the Three Niangzi, they still had a certain amount of power, so they entered the inner sleeve area, far away from the rights and wrongs of the Khan position of the Tumut tribe, and became an almost independent kingdom.

Examining the history of the rise and fall of the Mongols, the Mongols definitely did not lack leaders with wise temperament, but their rise and fall was based on the ability of individuals, not on the entire government or a group of abilities. Most of the Tatars in present-day Russia have a certain ancestry, while most of the indigenous inhabitants in the east are of Mongol descent, and half of the inhabitants of the five Central Asian countries are of Mongol ancestry. It is a pity that no matter where the Mongols arrived, in addition to looting and burning, they did not leave any more legacy, especially when a generation of strongmen died, the sons attacked each other in order to seize the throne, resulting in the decline of the country's strength and fragmentation, and then the Mongols were assimilated by the locals, rather than assimilated the local indigenous population, which is the reason why the inhabitants of the vast region, including Central Asia, have Mongol ancestry, and no one thinks of themselves as Mongols. Further back in history, the Huns also died out in this way, and although the Turkic people still existed, they had been *transformed and lost their previous traditions, which may be the greatest sorrow of the nomads.
