At twenty-five, Ye Li, a dentist in the 21st century, faints at the sight of blood while extracting a patient's tooth and transmigrates into the body of a poor thirteen-year-old girl in ancient times. Thus begins her rise to wealth!
Ye Li, a top dentist in the 21st century, is unexpectedly transmigrated to the historically nonexistent Great Yan Dynasty after an absurd fainting spell. She becomes Ye Ya, the thirteen-year-old daughter of a barefoot traveling doctor.
Her father's just died in a fall while gathering herbs, leaving the family destitute, creditors at the door, and a bully bent on selling her into a life of degradation.
In this desperate situation, Ye Li relies on medical knowledge far ahead of its time, especially her understanding of oral hygiene and surgical sterilization, along with a modern mindset and an indomitable spirit. She begins by treating villagers' toothaches, making “miraculous” tooth powder, and promoting the practice of rinsing one's mouth, gradually building a reputation and a fortune.
She must contend with the limits of her era, the jealousy of her peers, skepticism from the authorities, and even the power struggles of the elite.
But with science, sincerity, and wisdom, she not only cures countless people, but also builds her own business empire. In the end, she finds love and respect, and truly carves out a brilliant life of her own in the ancient world.
