Zhu Youxiao's purpose is to completely recover the entire Hetao region, and then vigorously develop to the west, with the help of the influence of the Tumut Mongol tribes to completely Mongolian this region, and then Sinicize it, change their living habits, improve their living environment, improve their production methods, make them recognize their country as the Ming Dynasty, and let the orthodox concept of the Ming Dynasty be completely integrated into their hearts.

Yuan Chonghuan took 50,000 elite soldiers out of the Yellow River from the side pass, and most of the supplies of the imperial court had been transported to Datong, which paved the way for Yuan Chonghuan's next plan. Yuan Chonghuan planned to take Guihua City in a battle, and then march westward, down the foot of Daqingshan and Yinshan, and pacify the entire Hetao area in one fell swoop, and then completely transform this area to make it an advance base for crossing Yinshan and Daqingshan into the vast Outer Mongolia region in the future.

Besides, Tumut's Chechen Khan Bu Shitu Taiji, since the return of Qinghai to the fourth "Shunyi King", the days are not as comfortable as he thinks, and he struggled to snatch the seat from the hands of Susang Taiji, but maybe he has given a lot of benefits to the right banner of the ten thousand households who support him, which is a big loss for Bu Shitu Taiji, both the annual income and rights have lost a lot, especially in recent years, affected by the climate, the general food has decreased, resulting in the current situation is becoming more and more sluggish. Coupled with Sunang Taiji's constant harassment, this made Bu Shitu Taiji miss his days in Qinghai very much.

Around the time of the Chinese New Year this year, many other small tribes migrated from the east, making the miserable life of Bu Shitu Taiji even worse. Sunang Taiji's behavior of sending troops to plunder the grain of the Han people gave Bu Shitu Taiji hope. Therefore, he also sent a lot of rangers to plunder the Han people near Taiyuan, but the scale of his dispatch was small, which did not attract the attention of the Ming court, and was considered to be just an ordinary bandit robbery.

The Ming Dynasty army quickly entered the Yellow River and quelled the harassment of Sunang Taiji, which made Bu Shitu Taiji both happy and worried, but he didn't expect the Ming army to really come to his territory this time. Bu Shitu Taiji did not want to lose his territory, he gathered 200,000 subordinate households, mobilized nearly 100,000 horses, and asked them to be deployed near Guihua City, preparing to fight a future-determining battle with the Ming army.

In Helinger Town, a squad of more than 2,000 people led by the three hundred households of Lu Xiangsheng, the vanguard of the Ming army, Li Hongji, Liu Zongmin, and Li Guo were these three hundred households, and they encountered the obstruction of one hundred households stationed here. The leader of the thousand households saw that there were 10,000 households in front of him, and he was a little scared in his heart, so he asked the three hundred households to be stationed and wait for the arrival of the follow-up troops. Li Hongji was born bold and full of gambling, he wanted to see how powerful these Mongols were, so he asked him to take Liu Zongmin and Li Guoshuai to a team of 1,000 people to attack, although Qianhu was timid, but he did not dare to show cowardice in front of his subordinates, so he agreed to Li Hongji's request.

Li Hongji, Liu Zongmin, and Li Guo quietly approached the vicinity of the army of Wanhu with these 1,000 people, and chose to have dinner at noon, first set up 30 mortars by Li Guo's team of 300 people, and carried out artillery bombardment on the Mongols who were eating for two quarters of an hour, and the artillery fire covered the entire town of Helinger.

The Mongol army, which was having dinner, was suddenly attacked by artillery, and it was a mess for a while, because they had never seen such a way of fighting, and in a hurry, Wanhu led a chaotic army of 3,000 to rush out. Li Hongji and Liu Zongmin rushed out as soon as they saw that someone was braving artillery fire, and rushed forward with their light cavalry, and now the distance between the two armies was only about 300 paces, and they came into contact in an instant. Li Hongji and Liu Zongmin each led a team of people, their formation is very peculiar, from the large formation is a herringbone, and then look at each team or herringbone, the smallest team is still herringbone. The leader of each herringbone squad is the strongest in combat, for the enemy who rushes up head-on, he is the first object of fighting, his first attack is to raise his left hand to the opponent's face or the arm holding the knife to shoot a crossbow arrow, and then in the case of the opponent's temporary loss of combat effectiveness, the assistant on the left or right is a knife, the cooperation of the three is just right, basically can do no damage to kill the enemy. No matter how much the opponent has an advantage in the total number of people, they always maintain a three-on-one combination of tactics in local battles. The new type of tactics is invincible, the new type of saber is extremely sharp, even if there is a leak and the enemy of the Ming army will be cut off by the standard saber of the Ming army, and will be chopped to death by another squad later, all the soldiers do not have to care about the back and sides, there are handed over to their comrades.

In less than a quarter of an hour, the two teams of Li Hongji and Liu Zongmin completely penetrated the formation of the Mongolian cavalry, like a sharp saw, sawing the Mongolian cavalry of 3,000 people into three planks, and there was not a single living cavalry in the place where they passed. Turning around, the cavalry on both sides circled again, and it was another perfect strangulation. More than 3,000 Mongolian cavalry went through these two piercing strangulations, and less than 1,000 remained, while the troops of Li Hongji and Liu Zongmin were almost intact. The one-sided battle ended in less than half an hour, the Mongol cavalry was completely defeated, and only a squad of more than a thousand Ming troops had completely occupied the small city by the time Qianhu arrived behind.

When Yuan Chonghuan arrived at Helinger with the main force, Li Hongji and they had already prepared tents for accommodation. When Lu Xiangsheng reported Li Hongji's battle process to Yuan Chonghuan, Yuan Chonghuan was very surprised, he himself did not expect that the current Ming army's combat effectiveness would be so high, and the Mongolian cavalry would be so unbeaten.

The Mongolian Wanhu, who was lucky enough to save his life, fled to Guihua City with the remnants of less than 1,000 defeated generals, and also reported the battle to Bu Shitu Taiji. At first, Bu Shitu Taiji did not believe in such an outcome at all, but with the arrival of the embarrassed soldiers, he completely gave up the courage to confront the Ming army, and decided to withdraw from the Naturalization City as quickly as possible, avoiding the fierce Ming army.

Bu Shitu Taiji's wise choice had just begun to be implemented, and Yuan Chonghuan's team had already driven to the city of Naturalization. There was no need for the Ming army to open artillery fire to attack the city, and Bu Shitu Taiji had already escaped from the wide open west gate with his team. This time it was Yuan Chonghuan who was caught off guard, he thought that Guihua City was the Khan City of Bu Shitu Taiji, and he had to attack it for a while to seize it, but he didn't expect that Bu Shitu Taiji had been frightened by the fierce attacks of Li Hongji, Liu Zongmin, and Li Guo, and fled without waiting for the Ming army to open fire.

Lu Xiangsheng reacted quickly, and as soon as he saw Bu Shitu Taiji leading his subordinates to escape, he led his Hetao light cavalry to quickly chase down. The speed of the Hetao light cavalry was very fast, and Bu Shitu Taiji only escaped for more than a dozen miles before he was caught up. In a hurry, Bu Shitu Taiji sent 30,000 households with 30,000 cavalry to block, but was divided into three ways by Lu Xiangsheng's troops, and penetrated in a quarter of an hour, with distant artillery bombardment and close slashing, the Mongolian cavalry of 30,000 people was completely defeated in less than an hour, so frightened that Bu Shitu Taiji could hardly even sit still.

Fortunately, Yuan Chonghuan understood Zhu Youxiao's purpose, and sent someone to inform Lu Xiangsheng not to chase too hard, just follow closely, so that Bu Shitu Taiji escaped with his life, and almost all the Mongolian tribes who took away the jacket of the Hetao fled to the Qinghai region along the banks of the Yellow River. On the way to escape, because the supplies were not enough to consume, Bu Shitu Taiji ordered to loot the residents near Yinchuan, and almost all the residents near Yinchuan except for the Han people were plundered, and all the property was used as provisions, and Yinchuan almost became a no-man's land.
