A noble prince on an isolated island was born frail and sickly. He was told that he had two years to live, so he turned around and ran away from home with a servant.
Both of them are mortal bodies without any martial arts, and one of them is a noble prince who may die at any time, and he is brave enough to venture into the world.
On the way, he met an immortal king and decided to blackmail him!
(Whatever) A plain and noble young man ✕ (Who are you) An arrogant and proud man?
