She was a genius physician from a family of traditional Chinese medicine practitioners, but after ten years of hardship in a post-apocalyptic world, she developed a cold and ruthless heart. One night, she transmigrated, becoming the despised, good-for-nothing, and foolish eldest daughter of the Marquis of Dingguo. From then on, she rose from the ashes, a seemingly useless woman making a comeback. With her left hand, she used her medical skills to bring the dead back to life, heal wounds, and revitalize her family; with her right hand, she seized divine treasures and slapped faces repeatedly. However, she inadvertently provoked a certain two-faced, thousand-year-old demon.
