Cleared at the End of Ming Dynasty

On March 19, the 17th year of Chongzhen, Li Zicheng, the "Emperor of Dashun Yongchang", captured Beijing, and Zhu Youjian, the last emperor of the Ming Dynasty, hanged himself. Only 34 days later, Li Zicheng fought against Wu Sangui and the Qing reinforcements at Shanhaiguan, and the Dashun army was defeated in a stone blow. At the same time, Li Zicheng's adopted son Li Yan looked at the mountains of corpses and seas of blood in Shanhaiguan and decided to do something.
