Shen Zhaoning, the legitimate daughter of the prime minister’s household, becomes a slave overnight. A transmigrator’s soul awakens within her, and she endures humiliation as she fights back with poison and strategy. Yan Wugou, the frontier’s God of War, bears a secret curse. She sees through his origins at a glance, and the two go from using each other to entrusting their lives to one another. Pei Yunheng, daughter of the Grand Tutor, plots in secret; Qin Xiao, the Embroidered Uniform Guard, holds irrefutable evidence; and salt merchant Xie Zhiwei commands the wealth of the realm. They are all pawns on her path to the throne, yet also bonds she cannot bring herself to sever. When a bloody edict tears through the ironclad rule forbidding women from taking part in government, she will make the realm her chessboard, move the pieces with her own hands, and ascend the throne.
