This is a historical novel that fictionalizes history. Of course, even if it is fictional, there are prototypes. The current opening chapter is based on the Han Dynasty and Han Wen Emperor Liu Heng. It restores what I think the difficulties that Han Wen Emperor faced when he ascended the throne: powerful heroes (the historical prototype is Zhou Bo, here I call him Liu Bo, and He is the current "villain"), the imperial power has declined because of his existence, and there are also the problems of vassal kings and feudal states that cannot be eliminated. These are the internal worries of the Han Dynasty, which is the Apocalypse Empire in the book, as well as foreign aggression: the powerful Hunran Empire in the north, the prototype is the nomadic Xiongnu in the north, Zhao Tuo in the south, etc. These all need to be solved one by one by the protagonist Wang Heng. As for why the protagonist's surname is Wang, it is because there was no unified emperor with the surname Wang in ancient China. As a common surname, it is used here. It restores the struggle between imperial power and prime ministerial power in my mind, and also allows readers to further understand "those things about ancient emperors"
