In the turbulent Dayu Dynasty, the queen consolidated power and replaced the prince with the son of a palace maid, the prince Xiao Jingyan. In order to deceive others, she promoted her biological daughter to Princess Zhaoyang. The prince knew his life experience early and regarded the princess as the biggest threat, so he repeatedly killed her. With extraordinary wisdom and foresight, Princess Zhaoyang worked step by step to resolve all crises in advance and secretly weaved her own power network. When the queen realized that her daughter was out of control and even threatened her own power, mother and daughter finally turned against each other. Princess Zhaoyang did not rely on any external force, but relied entirely on her own strategies and advance arrangements to finally overthrow the prince and queen, step on the corpses of all of them, reach the top of power, and become the eternal empress.
