Shen Zhiwei, a top modern-day female physician of traditional Chinese medicine, falls off a cliff while gathering herbs and wakes in the body of a low-born daughter in a powerful ancient family.
The inner household is a cage, etiquette is a shackle, her stepmother mistreats her, and she is being forced to marry an old marquis. She would rather die than submit.
On the eve of her wedding, she resolutely runs away, breaking free from the powerful family's cage and heading for the freedom of the wilderness.
Deep in the forest, she encounters Mo Hen, a woman in black who is on the verge of death. Guided by a healer's compassion, Shen Zhiwei risks everything to save her, earning a lifetime of steadfast companionship and quiet protection in return.
From then on, she sheds her noblewoman's identity, shoulders her herb basket, takes up her silver needles, and travels throughout the lands of Great Jing, searching for medicinal herbs in deep valleys and saving lives in the countryside.
She has no interest in household intrigue or powerful people, only in staying true to the healer's path.
A cold-blooded assassin stays hidden in the shadows, keeping her safe along the way;
her loyal maid Zhu He remains at her side, helping with the daily work of treating patients.
With silver needles she heals people, and with medicinal herbs she cures their illnesses. She breaks prejudices against female physicians, eases the suffering of the world, and writes a free-spirited legend of a woman healer.
