The Ten Halls' Underworld Emperor

I was once the ruler of the Underworld, but in this life I became a useless live-in son-in-law in the Netherworld.

Only when the Nine Hells shattered, reincarnation collapsed, and the Ten Yama Kings bowed before me did I remember who I was.

“The Heavenly Emperor? He was nothing but a dog I raised back then.”

A million ghost soldiers kneel, and the heavens tremble through the ages. In this life, I will reclaim dominion over life and death and crush the Nine Heavens!
