Tao Fang, the eldest daughter of the Zhenguo General Mansion, was born with the shackles of family honor and ethics. She has a beautiful appearance, but is famous for her martial arts and intelligence. As a noble girl, she is unwilling to be trapped in the backyard of a deep house.
When she first entered the world, she calmly dealt with the pressure of her concubine's overt and covert attacks and the pressure of family marriage in the turbulent general's mansion. In an accident, she met the prince Zhao Bin who was investigating the case incognito, and impressed him with his courage and wisdom. From then on, the two met by chance and became close friends. They gradually became each other's most solid support in the game of imperial power and disputes in the world.
As Prince Jing becomes more rebellious and undercurrents surge in the court, Yu Fang not only helps her father stabilize his military power and resolve the crisis, but is also accidentally involved in the secrets of the world - it turns out that her life experience is closely connected to the secret treasure of the previous dynasty and the "Mo Pavilion" of the Jianghu organization. Faced with the betrayal of her concubine, the pursuit of Prince Jing, and the mystery of her life experience, she wields a sword to break the situation, explores the truth amidst the light and shadow of swords, and sticks to her true heart in the whirlpool of power.
From the eldest daughter in a deep house to an ally in the world, from a court counselor to a queen, Yu Fang stirred up the storm as a daughter, broke the shackles of gender, and joined hands with Zhao Bin to put down civil strife and create a prosperous age. Her legend is a growth in the light of swords, a perseverance in power and tactics, and a sonorous war song belonging to women.
