Sun Jinyun, a son of a thousand households in Yongning, Luoyang in the late Ming Dynasty, was shot by a stray arrow while fleeing. After coma, he awakened the memory of a history-loving otaku in his previous life. Later, in order to avenge the murder of his parents by the intruder Li Zicheng, he endured the humiliation, kept a low profile, and led his sister to start a business with more than thirty people.
He first recruited troops and bought horses to pacify the bandit camp and met the heroine Zhang Qiyun. Then he turned south to find a peaceful place to establish a base. Then he developed business and strengthened his power and occupied the entire Ganzhou Prefecture. When Li Zicheng fled south to Hubei, he led a surprise attack and killed King Chuang.
After returning to the base area, Sun Jinyun first separated Jiangxi Province, then annexed Lingnan, and finally defeated the heroes from south to north to unify China, allowing the people to live a peaceful life.
