Gongsun Changting was born into a noble family. Her ancestors were founding heroes of the Great Chen Kingdom, and every empress of Great Chen had come from the Gongsun clan without exception. From childhood, Changting was taught how to be a virtuous, gentle, and benevolent woman.
But only after becoming empress did she understand that virtue and gentleness couldn't win the emperor's affection, while benevolence only encouraged his favorite consort to push her luck.
So she decided that rather than scheme against men or the women who schemed against them, she'd go after the power behind the men.
P.S. No rebirth, transmigration, or golden finger. A noblewoman who relies on men, family, and herself. A heroine who grows over time.
