Humans, demons, devils, and ghosts all possess spirits. In the mortal realm, there are demon hunters whose sole duty is to hunt down every monster they can find, claim its demonic spirit for their own use, and improve their cultivation.
But I’ll kill any god who stands in my way, destroy any Buddha who opposes me, and slaughter anyone who crosses me!
Bow before the demon for three thousand years, then turn back toward the mortal world and forsake immortality! I am the demon!
