Jiang Xi, a female doctoral student from the twenty-first century, opens her eyes to find herself a beggar at the very bottom of a feudal dynasty. Human lives are treated like weeds and dignity is trampled. She watches this cruel, cannibalistic world with cold detachment, clinging to one belief: survive, at any cost. A bloody massacre involving the destruction of a family is just around the corner. She catches a glimpse of the secret plot to frame the family, but her instinct for survival makes her stay silent.
But fate has other plans. A substitute is drawn into the game, bent on revenge.
When Chen Qiuhe is thrown into a death-row cell for trying to expose the truth behind the massacre, Jiang Xi finally sheds her cold facade. She begs people everywhere and debates the assembled ministers, all to buy him a chance to live. When the tyrant secretly imprisons him in the palace and subjects him to torture, she resolutely cuts off her long hair and dons armor! Taking on a man's identity, she commands the rebel army and marches straight for the imperial capital! When the palace falls, she personally rescues her dying beloved from hell, yet in the end, she cannot stop him from reaching the end of his life.
After this blood-soaked redemption, she stands atop the ruins.
The substitute who once coldly protected herself becomes the one who cages the dragon.
A new dynasty is established, and an empress takes the throne. What she means to change is not only her own fate, but the path on which countless women under heaven have been trampled. Taking his legacy as her flame, she will burn this rotten old world to the ground!
