Yuezhaofan, a medical cultivator from Qingling Valley, possesses superb medical skills but suffers from the odd quirk of retching whenever she smells medicine. Yun Guizhou, the first disciple of Tianxuan Sword Sect, seeks medical help due to severe, near-fatal injuries. Despite frequent bouts of retching, Yuezhaofan uses her advanced acupuncture techniques to save his life and accompanies him back to the Sword Sect for subsequent recuperation. During her time at the Sword Sect, Yuezhaofan calmly resolves challenges from disciples, building a deep friendship with the stern Yun Guizhou and the lively Yun Xiuxiu. Afterwards, she declines their entreaties to stay, returns to the valley to repair fellow disciples' magical artifacts, and secretly guards the sect, showcasing the true essence of a medical immortal who appears nonchalant on the surface yet is profoundly deep, loyal, and righteous.
