Shen Zhaorong was framed by her sister-in-law Shen Zhaoyao, and was sent to a military camp where she suffered all the humiliation. She endured and lay dormant, forged an iron cavalry with blood and fire, brought her old troops to fight back, and smashed through the imperial city's royal gates with her iron hoofs. The prince Pei Mingche secretly arranged the plan, the imperial physician Su Yunxiu turned against him, and the bandit general Han Lie held the secret road map, but her biological sister, the noble concubine sitting high on the phoenix chair, actually concealed a shocking life experience that could overthrow the dynasty. This is not revenge, but a bloody ascension to the throne that rewrites destiny.
