Purple Qi Immortal Doctor

After learning that he had a useless Five-Element Spiritual Root, Jiang Chen had given up on cultivation and returned to his hometown to practice medicine. Then his childhood sweetheart brought him a copy of the Purple Qi Body-Nurturing Art. From that day on, he could channel true qi through acupuncture, and his prescriptions followed the principles of alchemy. Other cultivators: kill for treasure and shut themselves away to cultivate. Jiang Chen: see patients, prepare medicinal herbs, and, while he's at it, practice dual cultivation with the pretty junior sister next door to stay healthy. Until one day, an elder of the Hundred Herbs Sect is struck by a deadly poison, and the greatest doctors in the land are powerless. The physician in blue simply turns a silver needle between his fingers. “For this condition, there’ll be an extra charge.”
