Dragging My Frail Body Through Life, I Somehow Became a Demon

A noble young master on a lonely island was born frail and sickly. Told he had only two years to live, he turned around and left home with a servant.

Neither of them had any martial arts skills; both were ordinary mortals. One of them was a noble young master who could die at any moment, yet they blithely set out to roam the jianghu.

They met an immortal lord along the way, and the young master decided to latch onto him!
