Awakening the Underworld System, I Recruit Yin Soldiers to Subdue All Realms!

What does it mean that I am dead? What does it mean that I have awakened from life and death and become the Son of Heaven? The system is the system, what's wrong with forcing yourself to live or die? Traveling through fantasy and becoming the Son of Heaven, since there is no god in the world, then I am the supreme god! The world is filthy, and humans and ghosts coexist. The underworld is coming! Give the world a bright future! "All heavens and all realms, all living beings in the universe, I, Netherworld, control the reincarnation of all living beings, and I will return to the top of all heavens!"
