During the Dajing Dynasty, dark undercurrents surged in the imperial court. A meticulously planned conspiracy caused the upright scholarly family, the Zhao family, to be burdened overnight with the crime of treason, leading to the destruction of the entire clan. Zhao Ning, the legitimate daughter of the Zhao family, narrowly survived.

In the eyes of outsiders, Gu Yanci was ruthless, cold-blooded, and deeply calculating, known as the number one powerful official who terrified all civil and military officials. However, Zhao Ning gradually discovered that this seemingly cold and ruthless Prince Regent had always protected her in secret and guided her growth step by step.
