This novel is set in an original dynasty that is similar to the ancient Chinese feudal dynasty, but with "hidden deviations" in its core rules - the Yong Dynasty (not the Tang, Song, Ming and Qing Dynasties, and no historical prototypes are copied). It was founded 187 years ago and has gone through seven generations of emperors. It is currently in the middle of the reign of the eighth emperor "Yonghe Emperor" (reigned for 11 years).
On the surface, Dayong is a typical farming feudal dynasty with strict hierarchy (emperor-nobles-gentry-commoners-tenants-slaves). It implements imperial examinations to select officials (including civil and military examinations, and a "secret subject" exclusive to the royal family). Confucianism is the superficial orthodoxy, and agriculture As the foundation, the handicraft industry (textile, iron smelting, porcelain making) is relatively developed, and the border is bordered by the "Beishuo Barbarians" and "Xilong Ancient Kingdom". There are small-scale wars all year round. Internally, there are two major interest groups, the Jiangnan nobles and the Guanzhong nobles, to check and balance each other, and there are undercurrents in the court.
