I'm No Mortal

Luo Tu was once one of the elites, but he lacked spiritual talent, and he couldn't awaken his spirit. After five failed attempts, his family gave up on him and exiled him to the underworld for cultivation. He had to start as a lowly undertaker, and learn various survival skills at the trade school, as he tried to build up his wealth to make another attempt at spiritual awakening.
