The late emperor passed away and the young emperor succeeded to the throne. The Queen Mother Su Jinyao, who was in charge of the affairs behind the curtain, was forced into the cold palace by powerful ministers. After three years of dormancy, she used meekness and weakness as her armor, and people's calculations as her blade. She fought back in a desperate situation, poisoned her political opponents, deposed the new emperor, and returned to the court as the Queen Mother. She personally promoted Xiao Yan, a silent and forbearing son of the clan, to the position of regent. She wanted to use it as a chess piece, but she didn't know that he had already laid a trap and always wanted more than power.

His love twisted and destroyed, intending to drag her into the abyss along with this majestic imperial power. Su Jinyao navigates step by step amid the swords and shadows in the court and the tender trap of the harem, dealing with two unfathomable men. In the shocking reversals, she must defend the country, and more importantly, find out her true heart. In the end, she will rise to nirvana and take charge of her own era.
