The State of Shang, the weakest nation, has lost another war. To humiliate Shang, the victorious State of Yan demands that one of Shang's princes marry into Yan and wed its notorious Sixth Princess.

Qiu Sheng, the Fifth Prince born in the cold palace with no connections, is chosen for the marriage. On their wedding night, as Qiu Sheng prepares to fight to the death, they discover that the Sixth Princess is not only not a hideous monster, but is also, like Qiu Sheng, of uncertain gender.

Jun Ye is the so-called Sixth Princess of Yan, famed in rumors. On their wedding night, Jun Ye intends to personally kill the consort sent by the crown prince, but one touch reveals that this consort is actually a woman.

As they spend more time together, the two fall for each other. Jun Ye plots her moves carefully, takes part in the struggle for the throne, and ascends to the throne. In the end, she rules the world alongside Qiu Sheng.
