Su Yu, the shopkeeper of the embroidery shop, was divorced by Xiao Yi, the prince of Dingbei Hou, on the grounds of "vulgarity and lack of talent", and fell into family humiliation and livelihood crisis. Relying on the amazing chess skills she learned in the chess club when she was young, she combined the management of the embroidery shop with the wisdom of "breaking the game". She used street games, gambling contracts, and chess meetings to become famous, and counterattacked step by step in the ancient "chess game"-like survival challenges. From being an "abandoned wife" whose engagement was broken up to being hired as a "chess master" by the royal family, she not only slapped the betrayer in the face, but also uncovered the mystery of her life experience when she was abandoned, and finally changed her destiny with her chess skills and became a "game breaker" that stirred up the turmoil in the capital.
