Awakened the Underworld System, I Recruit Yin Soldiers to Subdue All Worlds!

What do you mean, I'm dead?

And what do you mean, I awakened the Book of Life and Death and became the Yin Celestial Emperor?

A System is a System. Why does it have to call itself the Book of Life and Death? What's wrong with it?

I transmigrated into a fantasy world and became the Yin Celestial Emperor. Since there are no gods in this world, then I shall be the supreme deity!

The mortal world is filthy, and humans and ghosts coexist.

The Underworld descends! I will restore order to the mortal world!

"Across the Myriad Worlds, among all the beings of the universe, I, Youming, command the reincarnation of all life and shall return to the summit of the heavens!"
