Modern doctor Wu Yi transmigrates by accident to the resource-scarce 1970s.
She becomes a mentally disabled orphan adopted by the Xu family. The original owner was shoved down hard by Grandma Xu, struck her head, and died with bitterness in her heart.
Everyone thinks the foolish girl adopted by the Xu family is useless dead weight, but they don't know that someone else's soul now inhabits her body.
When a child chokes on a foreign object and is at death's door, she steps in to perform emergency treatment. When the villagers suffer mass food poisoning, she uses herbs to avert a crisis. With a few needles, she cures the baffling illness of an official's daughter.
She quietly reveals her medical skills and gradually earns herself the title of Little Miracle Doctor.
Facing awful relatives who despise her but still want to bleed her dry, as well as village gossip and criticism, Wu Yi relies on her medical skills and intelligence to protect herself and fight back, carving out a life of her own in these hard times.
