Synopsis

Grand Prince Jinseong visits a scholar's son requesting access to his father's smallpox research, due to the King's illness and Grand Prince Changnyeong contracting the disease. The son, initially hesitant, agrees. They discover a medical log including a Sanskrit text that might have details on preventing smallpox, leading them to seek help from a monk skilled in the language. It is revealed that the scholar's son, a butcher, had been trying to locate that information and that he is also a modern day teenager.
