Protagonist: Zhu Xiaolang (identity after time travel: King Xin Zhu Youjian -> Emperor Chongzhen Zhu Youjian)
Previous life: An ordinary 21st century social animal/history buff/talk show enthusiast/funny video blogger named Zhang Wei. He has a salty personality, is good at making complaints, is a bit clever, and is familiar with the historical facts of the late Ming Dynasty, but lacks practical experience. The biggest wish is to lie down, but we are forced to open business. The catchphrases may be "This generation of ancient people is really difficult to lead", "My blood pressure is too high", "System, you should be a human being!".
This life: Young King Xin/Emperor Chongzhen. He has a handsome appearance, but occasionally displays escaping eyes and strange expressions that are inconsistent with the times. In the early days, he was considered by the ministers and the harem to be "overly frightened" or "enlightened". Later, he was considered to be "unfathomable" and a genius emperor who could make jokes and curses well.
