A man who became a Eunuch raw

Manseok, a lowly slave who was abandoned in the mountains at birth because he stole the energy of the Samshin Halmae, is fortunately picked up by a wandering merchant and begins wandering the eight provinces of Joseon. With his natural talent for speaking and cunning, Manseok becomes a successful conman and a chivalrous swindler. Believing that "a famous swindler will starve to death," he prepares one last heist. His ultimate goal is to steal the blue and white porcelain of Park Daegam, the richest man in Hanyang. However, he fails and is captured. After being ordered by the swindler to become a "fake eunuch" and infiltrate the palace... and even more so, as the exclusive eunuch of Queen Gyeongye, who is said to be more fearsome than the king himself!
