In the twenty-eighth year of the Great Yu, the wind and rain were like darkness, and the imperial power was in decline.
When the eldest princess Yu Wanyin was twelve years old, her father was newly deceased. Later, she saw with her own eyes that Concubine Li secretly committed a murderous act, causing her mother to burn herself to death and her younger brother to be weak in the womb since he was born.
She endured the humiliation, abandoned her red makeup, practiced tactics, and practiced martial arts. Surrounded by tigers and wolves, she fought every step of the way, just to protect her only younger brother and guard the last trace of Dayu's royal lineage.
The traitor is fair, the noble concubine wields power, the feudal king peeks into the cauldron, and the government and the public are in turmoil.
Playing chess as a princess, she joined forces with Xiao Ce, the prince of Zhenning, to eliminate traitors, set the course for the court, support the young master, and stabilize the world.
When the mountains and rivers stabilized, she walked away, leaving only a long song of Dayu that has been passed down through the ages.
