When he was six years old, Hu Xiaobao was brought back to the wealthy Hu family from the countryside by his biological parents, but found that he was just a substitute for the fake daughter. The real daughter Hu Tingting was pampered by her family and grew up, but she, the "real daughter", was only qualified to live in a servant's room. Autism made her taciturn, but she unexpectedly awakened the "sense of all things" golden finger - she could hear the whispers of plants, the voices of animals, and even see through the good and evil of people's hearts. When Hu Tingting designed her to be exiled to an old house in the countryside, Hu Xiaobao took a garden full of flowers and plants and a stray cat to start an "autistic" healing life. She didn't know that the thousand-year-old tree under the old house had already awakened, waiting for the contracted owner; she didn't even know that the young bamboo horse boy who seemed as gentle as jade had actually been guarding him secretly. On the way to escape, she cured the villagers' stubborn illnesses with a piece of grass, resolved the family crisis with one sentence, and caused a sensation in the city with a flower. When the Hu family suffered a disaster, everyone discovered that the little mute who never spoke was the real head of the family.
