Six years after the founding of the Dayue Dynasty, Xie Heng, the Marquis of Wuwei, lay dormant for five years and finally returned to Chang'an from the border town. His father, Xie Bochong, died violently and was imprisoned for "treason" five years ago, but the real culprit is still in the court - the Ji family is spread all over the court and the public, Lieutenant Li Tan holds heavy troops, Prime Minister Xie Boxing is cold-blooded and brutal, and eunuch Huang Anquan has dominated the inner court. Everyone owes a blood debt. Xie Heng returned with deep-seated hatred and sophisticated planning, and worked step by step in the whirlpool of power. On the Qing emperor's side, he killed Ji's family and liquidated everything - this was a revenge that used the entire court as a chessboard and would not end until death.
