In a "Huang Dynasty" similar to the prosperous Tang Dynasty, the empress was old and the court was in chaos. The protagonist of the story is a former prince who was demoted from the East Palace due to an unjust case and was thought dead by everyone. He has been dormant among the people for ten years and transformed into a ruthless leader of a secret organization. He holds a "Phoenix Edict" that can overthrow the dynasty, and vows to burn the empire he once swore to protect to the death. And his main opponent was none other than his once most loyal prince's companion, the Commander-in-Chief of the Imperial Guard, who now swore allegiance to the empress.
