Lin Jiuge, a genius of Chinese medicine in the 21st century, traveled to the Jiuxuan Continent due to a laboratory explosion and possessed the "waste girl" who is a direct descendant of the Lin family in Cangwu Country. The original owner was abandoned by his family because he was unable to cultivate Xuan Qi, and was sent to a small border town. After awakening from the Medicine King Cauldron (which contains the "Hundred Herbs Manual" and the library of ancient medicinal materials), I discovered that I was actually the blood of the King of Medicine, and that my mysterious veins could control the "qi of life and death" (treatment and poisoning in one).
