Yan Ruoxi, a renowned physician of the Celestial Dynasty, is murdered and unexpectedly transmigrates into the body of the prime minister's legitimate eldest daughter, who was abandoned in the wilderness. A cold, wounded prince being hunted is lying right on top of her.
And so she begins her revenge, tearing into her stepmother and tormenting her scheming half-sister until the entire household of the prime minister is thrown into prison.
The cold-faced prince suffers from a terrible illness and a deadly curse on his marriages. On every full moon, he transforms into a red-eyed werewolf, and no one can treat him.
Yan Ruoxi uses her medical skills to cure him with a single dose, but he devours her whole.
A year later, pregnant, she opens a clinic in the wilderness and becomes a famous doctor throughout the region.
Only when the aloof prince kneels before her and begs her to return do the common people learn that she is the domineering and arrogant Ninth Princess Consort.
