This long Machiavellian romance novel is set in an imaginary ancient times. It tells the story of Shen Qingci, the princess of the Great Zhou Dynasty, who grew from a chess piece who was forced to marry in troubled times to a legendary woman who mediates the Three Kingdoms and creates peace.
After three years of marriage, Lu Beichen, the Marquis of Zhenbei, was about to go on a northern expedition. The prince colluded with powerful ministers to force the palace to seize power. In order to save her husband's life, Shen Qingci resolutely signed the letter of divorce and married away to Beidi. She thought she would be trapped in a political marriage for the rest of her life, but she met the unfathomable Beidi Wang Yuwenting - the young man she accidentally rescued ten years ago, who now hired the entire grassland, and started an affectionate game based on respect and wisdom with her.
