The Imperial Family's Little Physician

In her previous life, she loved the wrong man, watched her family die horribly, and died consumed by hatred. When she opened her eyes again, she had been reborn. No longer weak and timid as before, she became cold-hearted, calculating, and utterly decisive, determined to kill every one of her enemies. Once a legitimate daughter everyone despised as weak, she now handles everything with ease: curing stubborn diseases, dissecting hearts, tormenting scoundrels, earning military honors, and turning the court upside down. With her own strength, she changes the world and defies fate. Overnight, she becomes everyone’s favorite. Even the Medicine King wants to become her apprentice. Wait, why is the handsome prince she rescued on a whim taking off his clothes to pay his medical bill?!
