In her previous life, she was the last tyrant of the Dashuo Dynasty, "Ming Sui Yu", who burned herself to death when the rebels captured the imperial city. When she opened her eyes again, she was reborn as an enemy country - a cold palace maid with the same name in the Dasheng Dynasty, which had just experienced palace changes and internal and external troubles. At that time, Xie Xuanyao, the new emperor of Dasheng, was decisive in killing and was following the path she was familiar with in her previous life, which was to centralize power with an iron fist but ultimately lead to betrayal and alienation.
Therefore, in the court, she is an ant-like palace maid; in the dark night, she is a ghost who knows all the directions. She watched with cold eyes as he repeated the mistakes of her previous life, and was horrified to discover that her current life and death were subtly connected with the national fate of His Majesty, the "control group". In order to save herself, she had to use anonymous strategies to persuade him, and as a palace maid, she quietly reversed the tragedy at a key node. Xie Xuanyao gradually realized that there was a pair of invisible hands around him, pushing him away from the established abyss. He began to frantically pursue the figure in the mist, but he didn't know that the biggest variable was the seemingly docile and cowardly little palace maid in front of him. When the soul of the "tyrant" is trapped in a humble body, and learns from each other's "tyrants" in this world, a legend about redemption, game and subversion is quietly staged within the palace walls.
