What is the main purpose of Ming's founding camp? Why did it finally disappear?

The battalion founded by Ming Dynasty is a modern army. Every soldier put a sword and halberd in his hand, but gave everyone a musket. This was the first army equipped with hot weapons in the ancient feudal dynasty. Judy is an excellent general and a very famous strategist. His military concept is very advanced. At that time, firearms in the Ming Dynasty had developed to a very high level. Judy had a whim, equipped an army with muskets and set up a magic battalion to deal with Mongolian cavalry, which achieved good results.

After the Ming Dynasty overthrew the rule of the Yuan Dynasty, the people of the Yuan Dynasty returned to Mongolia. They always wanted to return to the Central Plains and restore the rule of the Yuan Dynasty. Therefore, in the history of more than 300 years established by the Ming Dynasty, Mongols have always been the biggest rivals of the Ming Dynasty. When Zhu Yuanzhang was alive, he was sent to attack Mongolian territory several times. After so many years of recovery and development, the Mongolians revived their vitality in Judy, and they once again challenged the Ming Dynasty.

The best of the Mongols is their cavalry. Cavalry was a modern version of tanks in ancient times, and it was very difficult for infantry to deal with cavalry in open areas. So Judy formed an army with muskets to deal with Mongolian cavalry. It turns out that Judy is right. He achieved miraculous results in dealing with Mongols. What he didn't expect was that Ji Shen camp played a vital role in the Beijing defense, defeated the Walla army and abandoned the armor, and held the last line of defense of the Ming Dynasty.

After the demise of the Ming Dynasty, the Ji Shen camp disappeared. After the establishment of the Qing dynasty, although an army equipped with muskets was also formed, they did not often use this army on the battlefield. The Qing Dynasty was a country founded by Manchu people, who were also nomadic people, so they trusted their horses more and believed that their own people did not trust these firearms.
