Sun Chuanting told the Mongolian soldiers that since they joined the army of the Ming Dynasty, everything must be required of the discipline of the army, and they must fight in strict accordance with the formulated combat methods and skills, and must not allow heroes to rely on their brute force to kill without permission, and must pay attention to the skill cooperation between comrades-in-arms. When the first person shoots, the person behind will immediately quickly insert himself into the enemy's flank and kill him; When the frontal enemy is difficult to resist, it is necessary to give way to the front, shoot from the side, and cut and kill from the back, but it is never allowed to retreat. In short, minimize losses and get the maximum win.

For the Han soldiers, Sun Chuanting asked them to become proficient in horses and the climate here as soon as possible, and to master the muskets and artillery in their hands. Skilled horses as soon as possible because this is the basic requirement for a fast march, in the vast northeastern plain and later the Siberian plain, a fast march speed will be the guarantee of victory in the war, and only a surprise attack can achieve the maximum effect. Familiarity, proficiency, and flexible use of muskets and artillery is the guarantee of victory, and when these near-modern weapons are brought into full play, it is difficult for any army of this era to confront them, and the purpose of Sun Chuanting's training is to enable soldiers to meet this requirement.

In the summer of the Horqin Mongolian steppe, a pair of Han and Mongolian soldiers were training in full swing, and Sun Chuanting gave them a training time of three months to become an army. In order to ensure the quality of training, there is no limit to the food of each soldier, as long as you train into a qualified soldier in these three months, you can let go of your stomach to eat, whether it is beef and mutton or rice, three meals a day, which is great news for the current soldiers, you must know that in the modern era to be able to eat enough is a great thing. In order to prevent soldiers from eating too fat, Sun Chuanting also specially stipulated that all soldiers who could not complete the training and were overweight would be cleared out of the army and go home to play with their children. As a result, three months later, these 30,000 soldiers were alive and vigorous, full of fighting spirit, none of them were eliminated and went home, but nearly 100 people were injured by the training, and Sun Chuanting did not treat them badly, but each of them was given cattle, sheep, and land to go back to the local area to serve as militia reserve instructors.

At the same time, the relationship between the Yehnara tribe and the Ming Dynasty was unprecedentedly friendly. Since Zhao Shujiao helped the Yehenara tribe defeat the attack of the Nurhachi tribe, the leader of the tribe, Niyaha, asked Zhao Shujiao to drink almost every day, only to drink so much that Zhao Shujiao wanted to hide when he saw Niyaha. Anyway, at this time, Xiong Tingbi sent Man Gui over, and at the same time there was the newly appointed chief soldier Mao Wenlong, Man Gui was a little better, not good for this mouthful, but Mao Wenlong didn't care about meat and vegetables, women and wine all accepted, especially drinking, it was almost afraid of Niyaha, but fortunately, there was also Man Gui reconciled, and the relationship between these people was very harmonious.

When Xiong Tingbi explained the meaning of the imperial court to Niyaha, Niyaha also felt that it was definitely the best thing to be able to settle down and become a part of the Ming Dynasty, which was definitely the best thing for the tribes who had eaten up the lack of food and salt. Niyaha invited the elders of the tribe to his tent to negotiate, these elders have long been stunned by the firearms of the Ming army, especially the cruel massacre of Nurhachi made them hate and fear, and they wished to find a big backer, and now the Ming Dynasty put forward this condition is relatively generous, not only for food, salt, but also for the purchase of native products, for daily necessities, but also for the children to read and write, so after a little deliberation agreed to join the Ming Dynasty sequence.

After the Yehnara tribe was completely integrated into the Ming Dynasty, Niyaha was appointed as the prefect of Siping Province, and a series of management measures were formulated in accordance with the Ming Dynasty's management system. The land here is very fertile, and the situation of the Horqin Mongolian grassland is very different, Xiong Tingbi is in accordance with the main way of life to plant crops, because the summer here in the northeast is shorter, the general crops can only be ripe once a year, so the remaining half a year is mainly hunting, each small tribe is divided into hundreds of small villages with the patriarch as the leader, and then with the help of the Han people who have migrated over one after another, they began to build houses and learn to plant. According to Zhu Youxiao's intentions, it is necessary to change these nomadic Yehnara tribes into semi-agricultural people who mainly focus on agriculture and supplemented by hunting, so that they will not move around after they have fixed property.

"Yehe" in the Jurchen language means "porcelain", and "Nala" is the meaning of nostalgia, originally the Yehenara tribe has the meaning of leaning towards the Ming Dynasty, more like the lifestyle of the Han people, and now they can live in a down-to-earth way. Niyaha is not too old now, about thirty years old, for these Ming Dynasty officials are very fond of it, especially Mangui, now Mangui is also in his thirties, because he is not a woman, and he has not yet started a family, Niyaha asked Zhao Shujiao to be a matchmaker, and married his eighteen-year-old sister Dongmei to Mangui, Mangui saw that this Yehe sister was also very pleasing to the eye, so Mangui and Niyaha became brothers-in-law, Zhu Youxiao also made a lot of fun, and asked Sun Chengzong to write a good word and send it over.

Xiong Tingbi saw that the emperor liked Man Gui, so he recommended Man Gui to be the chief military officer of Siping, and assisted Niyaha to jointly defend Siping. Under Zhu Youxiao's instructions, Xiong Tingbi generously rewarded Niyaha and Man Gui, in order to thank the emperor for his grace, they decided to set up a mountain cavalry battalion based on the youth of Yehenala according to the emperor's opinion, the main task of this mountain cavalry battalion is not frontal combat, but reconnaissance and raid as the main combat methods. This mountain cavalry battalion is very suitable for Mao Wenlong's appetite, Mao Wenlong actually put down his shelf and begged Xiong Tingbi to lead this mountain cavalry battalion, even if it is from a general officer to a general.

Xiong Tingbi naturally didn't dare to agree privately, so he went to ask the emperor, because it was the emperor's intention to form this team, Zhu Youxiao was secretly happy in his heart, Mao Wenlong, this guy really had a vision, and now he saw the prospect of special forces. Historically, Mao Wenlong is indeed good at sneak attacks, and he is also good at fighting evil battles and fierce battles, this guy is resourceful enough, and it is indeed very suitable for him to serve as the commander of this mountain foot cavalry battalion. So, Zhu Youxiao issued an order, and Man Gui was in charge of his own troops and transferred them to Siping for training. Mao Wenlong served as the chief soldier of the Siping Mountain Infantry Battalion, and the men and horses he originally commanded were handed over to Zhao Shujiao, and his position and Yulu remained unchanged. The number of the mountain infantry battalion was temporarily changed to 3,000 men, of which 2,000 were selected from the warriors of the Yehnara tribe, and the remaining 1,000 were selected by Mao Wenlong himself from other troops in Liaodong, and the other troops had to be released unconditionally. Along with the holy decree came a thin training manual, which was a training manual written by Zhu Youxiao himself, and he wrote an outline based on the training methods of special forces found on the Internet in later generations and his own experience in practicing boxing, plus the weapons of this era and modern weapons, so that Mao Wenlong could standardize it according to his actual situation in military training.

Mao Wenlong, who received the holy decree, was overjoyed, he didn't expect the emperor to be so kind to him, especially when he saw the training manual, he admired Zhu Youxiao so much, he felt how great his mission was after reading the training manual. Mao Wenlong's moving turned into practical action, which made the team of recruits miserable, and they were trained unspeakably miserable, but no one was willing to give up, because the mountain cavalry battalion of 3,000 people was distributed according to double provisions, and it would be the most elite army of the Ming Dynasty in the future.
