Modern cities integrate extraordinary systems. Awakened humans are divided into levels from F to SSS based on their strength. Above that is the legendary "divine level" that can rewrite the rules. Ten years ago, the abyssal rift opened, and the crisis of annihilation swept the world. The god-level powerhouse "Sky Ember" single-handedly ended the war, sealed the abyssal rift, and then disappeared from the world, leaving his life and death unknown. For ten years, the supernatural world has been looking for traces of him, and the remaining forces of the abyss are also dormant in secret, waiting for opportunities to take revenge.
