After traveling through time, Shen Yun became the eldest daughter of the Marquis of Jing'an Mansion. The period of filial piety is about to expire, and all forces are eyeing her - her marriage affects the fate of hundreds of thousands of troops in the north.
The prince used his power to suppress others, the noble concubine set up a conspiracy, and the queen mother issued a decree to marry her away to the feudal king. Everyone regards her as a chess piece, but they don't know that she has already seen through the chess game.
She invited herself to the palace as a female official, used retreat to advance, and entered the game from a humble position playing chess.
During the party struggle in the previous dynasty, she glimpsed the secrets of the court from old memorials; during the war in the north, she used the trade route as a line to lay out a secret chess game; deep within the palace wall, the truth about her mother's death that year was emerging.
She wants to play this game of chess by herself. Not fighting for favor, not fighting for husband, just fighting for a position in the world of chess.
