Doctor Han Lee was a struggling practitioner of traditional Korean medicine until his life took a bizarre turn.

Using his extensive modern knowledge of acupuncture and internal constitution reform, he sets out to cure his physical vessel.

As Lachiel slowly regains his vitality, his unconventional treatments draw sudden attention. In a realm completely unfamiliar with alternative medicine, his skills seem like miraculous magic. The crown prince soon finds himself curing deadly diseases, navigating treacherous court politics, and gathering eccentric allies. To secure his survival, Lachiel must outsmart plotting nobles and looming threats, proving that a few well-placed acupuncture needles can be far more dangerous than any sword.
