Zhu Xiaozu, an entrepreneur born in the 1980s, is a generous man and loves history, especially the history of the Ming Dynasty. His family motto states that his ancestor is Zhu Cizheng, the fourth son of Emperor Chongzhen. Since he did not leave any evidence such as tokens and genealogy, the authenticity has long been unknown. After serving in the army for many years, he returned home to inherit his father's property. Unexpectedly, he was deceived and kicked out of his own company because he trusted a professional manager too much. He was so angry and had the blood of a soldier that he killed the professional manager with his own hands. He was desperate and imitated his ancestor Zhu Youjian, Emperor Chongzhen of the late Ming Dynasty, and hanged himself from a locust tree in Beijing's Jingshan Park. Unexpectedly, when he woke up, he became the ancestor Zhu Youjian, thus changing the fate of the Ming Dynasty.
