With her intelligence and quick wit, Su Tao gradually wins the emperor's favor while secretly reuniting with her mother. The mother and daughter form an alliance, working together to maneuver within the imperial court, counterbalance powerful ministers, repel foreign threats, and steadily seize control of political power, rewriting both their destinies and that of the dynasty.
