The story of the "late" prince Li Xuan quietly returning to Chang'an after three years of hibernation and playing chess in the dark. Faced with the fierce power struggle between the fourth prince and the eighth prince, he dealt with it in a sick and weak manner, using his strength to gain ground every step of the way. Between major cases such as the Zheng Yuanting corruption case and the Chunwei fraud case, Li Xuan used the world as a chessboard and people's hearts as pawns, just to regain everything that belonged to him in this unfinished chess game three years ago.
