The very essence of reality crumbled around their decaying corpses, their divine auras still gnawing away at existence itself.Atop the mountain of annihilated deities, a towering figure stirred.A shadowed colossus, muscles harder than celestial ore, veins pulsating with endless power. His crimson eyes burned through the darkness as he lifted a grotesque, pulsating sphere of dark flesh to his lips.With a grin, he bit down.The sphere twitched, still alive—still screaming—before it was reduced to nothing but nutrients.Wuji exhaled, his breath alone shaking the void.“Annoying little pests... at least they had some use.”
