Synopsis

The Crown Prince learns about a system called 'GDP' which accumulates from medical achievements and allows the purchase of 'lie vouchers', which guarantee someone will believe any lie told with them. He then travels to Cremo, a city in the empire, to promote his traditional medicine clinic. He offers free treatments, travel, and accommodation, successfully enticing people to visit his clinic. Despite working non-stop, he hides his fatigue to maintain his image.
