Shen Qingyao, the concubine daughter of the Prime Minister of the Dayong Dynasty, entered the palace draft in order to compete for her biological mother. However, because she looked exactly like the late empress, she was named "Yao Guiren" by the emperor. She worked step by step amidst the pressure from the queen and the win over the concubine: she used the flower viewing party to expose the concubine's poisoning conspiracy, and used her resourcefulness to help the queen mother resolve the crisis at the birthday banquet, and gradually gained the emperor's trust. When she discovered that the death of her biological mother was related to the queen, and that the emperor only used her as a "stand-in," Shen Qingyao teamed up with the frustrated third prince to set off a storm in the palace to seize the queen and the heir.
