The newborn princess Lingxi unexpectedly has the ability to read minds, but her voice can be heard by the emperor Mo Yuanqing. The emperor discovered that neither the prince nor the second prince was his biological son, but Lingxi was his own bloodline. The concubines and princes in the harem plotted against Lingxi one after another. The queen and the noble concubine colluded with their relatives to plot rebellion. Lingxi exposed the conspiracy for the emperor with the voice of his heart. Mo Yuanqing protects her daughter and cleans out the traitors and appoints Lingxi as the crown princess. Lingxi used her wisdom to resolve the clan's difficulties, grew up in the struggle for imperial power, and eventually became the only female crown prince of Daqi.
