Yao Ying, a modern social beast, wakes up and becomes the cannon fodder maid who dies at the beginning of the Qing Dynasty drama. When she opened her eyes, she discovered that the eunuch in charge, Wang Dequan, had poisoned the princess. Seeing that her neck was about to be broken and the well was filled, she blurted out a curse in despair and fear: "You are a rotten gelding!" - As soon as she finished speaking, Wang Dequan actually tripped over his belt and fell into the mud. The poisonous powder in his arms was sprinkled all over his body! He was not lucky enough to escape the disaster, but because the guards traced the source of the poison, he was implicated in the Crown Princess's "miscarriage". In desperation, he said "The Crown Princess should take care of the emperor's heir", which directly exposed the Crown Princess's huge conspiracy of fake pregnancy to compete for favor! The prince was furious, and the blade of the sword was hanging from his neck!
Since then, Yao Ying has been trapped in the whirlpool of the East Palace. Her treacherous "crow's mouth" that "follows her words" but has random out-of-control effects is not only a life-saving talisman in a desperate situation - she curses a guard to fall into a smelly ditch, points out the false account layer, and forces out the red poison sac on the top of a crane; it is also a life-saving knife - accidentally detonating the explosives hidden in Wang De's body, leading out Li Qiunian, the governor of Jiangnan, and even exposing the crown prince's cronies to treason with the enemy! From being regarded as a demon maid who pretends to be a god, to the taboo in the palace that makes the powerful people of the dynasty change their minds when talking about "crow", Yao Ying is forced to be caught between the cold and cruel prince, the crazy prince concubine, the undercurrent nobles and the remnants of the previous dynasty. She accidentally got involved in the unsolved case of Emperor Jianwen's Jade Seal of the former dynasty, and the emergence of the "treasure of peace and stability" set off a bloody storm that had been sealed for decades.
