Strong Invasion: I Bring an Underworld to the Demon World

Inadvertently entering a world filled with demons and ghosts as an "invading human race". Suddenly I discovered that there were only demons and ghosts, but no underworld. "The underworld system awakens." "Acquire the power of the Six Paths of Reincarnation." "With the power of animals, hammering bones to refine flesh, from yang to yin, humans and ghosts can be at ease!" "The power of Shura, refining gods and transforming wisdom, channeling consciousness, yin and yang in one thought!" "The power of hungry ghosts gives ghosts the power to control the life and death of all ghosts in the world!" "The power of hell exists as a human being, as a human being, as a law, and as a law is heaven, heaven and man decree, and all things obey the call!" I understand, it turns out that the underworld is me. I am the underworld! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
