Jiang Jinyan, as the lone emperor of the Nine Palaces, holds mountains and rivers in his hands but no one can trust him; Xie Qiwu is an orphan from the previous dynasty, hiding in a dark alley for ten years, tearing the world apart with a burning edict. When power schemes and blood feuds collided in the flames of war, he took the country to cast iron laws, and she burned the edict to prove her sincerity. Who says that the daughter of a subjugated country cannot rewrite destiny? Who says that a lonely person cannot abandon the world for one person? The fate of the two is like a knife, and love is poison and redemption. In the end, when the imperial power collapsed, one person put down the jade seal for her, and the other burned all the old laws for him.
