Lin Wan, a modern professional elite, accidentally traveled through time and became a queen who was deposed in the Great Xiao Dynasty and was trapped in the cold palace.
Facing the palace's poisonous plot, the emperor's suspicion, the provocation of her old favorite, and the pressure from the Queen Mother, she relied on modern wisdom and past life memories to fight back step by step.
She and the cold-faced emperor Xiao Lin went from testing each other and guarding each other, to secretly falling in love, and the emperor and empress worked together to pacify the harem, clear out the former dynasty, and resolve life-and-death crises.
Fettered by two lives and entwined by red threads, he picked out a girl for her and favored only one person; she helped him stabilize his country and create a prosperous world.
In the end, he gave up his Zen position and retired to the south of the Yangtze River with her. From having power over the world to the world of fireworks, he stayed with only one person.
