Lin Yan, a master of modern orthopedics, collapsed due to overwork and traveled through time to become a poor scholar during the Jiajing period of the Ming Dynasty. He has nothing but extraordinary orthopedic skills and the remaining talent for writing, and he also picked up a timid orphan named Xiao Yuan.
He couldn't bear the disturbance at home, where wives and concubines were fighting for favor. He accidentally heard that there was a female doctor named Su He with supernatural medical skills in the Qinghe Valley outside Qinghe Town. In order to find peace in Fangfang and for Xiaoyuan to live a stable life, he concealed his identity and sneaked into the Medicine Valley, where he made a living by copying medicine books and drawing diagrams.
He uses steel needles to pick broken bones, and she uses herbal medicine to rejuvenate life; he draws bones as accurately as living things, and she discerns qi and blood veins as delicately as observing lines. The collision of Chinese and Western medicine has gone from tit-for-tat to tacit harmony, and feelings are quietly growing in the fragrance of medicine and ink.
However, undercurrents surged in the Jiajing Dynasty, powerful officials were in power, corrupt local officials coveted the resources of the medicine valley, and the plague suddenly swept across. He and Su He not only want to save the people with their medical skills, but also deal with the powerful. When the steel needle and the herbal medicine finally fought side by side against life and death, and when he was about to ask to marry her in the name of a scholar, the familiar dizziness struck again - the operating light came on, and the scent of the medicine from the Qinghe River Valley and her smile became the most painful residual warmth in the palm of his hand.
Is this just a dream, or is the bond across time and space still unbroken?
