A Grim Reaper's Come to Claim Me? Don't Worry, Grandpa Knows People in the Underworld

I was born on the seventh day after my grandfather's death, and the Underworld chose me to be the reincarnated spirit of a soul reaper.

The King of Hell sent people to drag me back to the Underworld, but luckily, my grandfather stepped in just in time and took over the grunt work, serving as an ox-headed demon for fifteen years in my place.

I spent those fifteen years constantly cultivating, until at last I was qualified to take over from my grandfather and become a Yin-Yang Wanderer.

From then on, I carried out the duties of the ox-headed demons in the world of the living on behalf of the Underworld.
