The Taoist Doctor

Taoism has Five Arts: "Mountain (Nature)", "Medicine", "Destiny", "Physiognomy", and "Divination". The Arts are what make the Dao great. As a Taoist medical practitioner, Zhou Jinyuan can read a fortune, and, better yet, save lives. But being a doctor who draws protective talismans and practices alchemy—and a young one, at that—means he has to constantly prove that he really isn't a scammer!

Zhou Jinyuan: Need me to treat your illness? Hold on, let me finish this talisman first.
Patient: *terrified* ??? Sorry, my mistake!
