The Dayan Dynasty has gone through more than three hundred years since the founding of the country, and the throne has been passed down to the current emperor, who is the twelfth generation of monarchs. The current dynasty is facing a severe situation of declining imperial power. The foreign relatives' group relies on the power of the harem to interfere in the government affairs. The aristocratic families control a large amount of social resources and the power to appoint and remove officials, while the vassal towns in various places support their own troops and form a separatist situation. These three forces have formed a horn of mutual checks and balances. On the surface, the court seems to maintain a balance of power, but in fact, various forces are fighting openly and covertly, and the political whirlpool is turbulent, indicating that the dynasty is about to usher in major changes in the power structure.
