Feng, formerly a North Rangori Giant, underwent a startling transformation by consuming a cursed creature. On the other hand, Landross, a necromancer mage, wields forbidden genetic and rejuvenation magic, utilizing blood as its catalyst. In a peculiar pact, Landross offers his assistance to Feng under a single, non-negotiable condition: possession of Feng's soul. Landross harbors aspirations of currying favor with the dreaded Black Emperor, believing that the souls of not only Feng but also many others might serve as offerings to satiate the Emperor's appetite for power and dominance. This unusual relationship binds them in a dark alliance with unsettling implications for the fate of countless souls.
