In 1644 AD, the greatest disaster in the history of Chinese civilization was that barbarians ruled the Central Plains!
In 1629, there were still barbarians in Liaodong who were eyeing the situation. Bandits from Shanxi and Shaanxi were attacking the prefectures and counties like locusts. Natural and man-made disasters continued and the people were in dire straits. At this time, no one could turn the tide and the building was about to collapse.
A strong army broke out in Datong, drove out the Jurchens, defeated the bandits, and moved to the north and south to fight, making China once again stand on top of the world. See the journey of those who traveled through it in the late Ming Dynasty to become an army.
This is a historical legend written by little people.
