In the Hongmeng universe, the Immortal Realm lies above the Nine Heavens and Ten Lands, while the Underworld lies below. This is a world abandoned by the immortals, yet some refuse to be bound by heaven and earth. They rise above the Nine Heavens, descend into the depths of the Underworld, and become lords of their realm.
As time passes, immortals are no longer what they once were, and mortals are no longer so fragile. The immortals have begun to take notice of them. A slaughter born of the struggle for dignity is quietly approaching. They defy fate in a clash between humans and immortals. Who will rule the world? Across the Nine Heavens and Ten Lands, who can stand against them? They will fight their way to a brighter future.
