Daughter's Power, Hidden Gem in Imperial Palace

Empress Sanging and her unfaithful father, Su Wuyou, died tragically at the hands of Prince Wei in a past life, leading to the destruction of their nation and family. Reborn at four and a half years old, Sanging vows to reform her charming father and take revenge on Prince Wei. By making precise predictions, she gains her father's trust, enters the palace to act cute and help him avoid trouble, and earns the title of Princess Junzhou. Confronting Prince Wei's undercover agents and the love-inducing powder, Sanging plays along with their schemes. Later, she persuades her father to resign from the throne, forcing him to awaken his sense of responsibility. With Bai Zixu's assistance, the father and daughter use ancestral regulations to make Prince Wei the target of public outrage. Using their foresight to predict disasters and resolve palace uprisings, they eventually expose Prince Wei's treasonous evidence. Su Wuyou transforms into a wise ruler, and Sanging is enfeoffed as the Crown Princess, where the father and daughter join forces to protect the Great Xiliang.
