Demons and monsters disrupt the world, feeding on humans. Immortals and Buddhas are demons and monsters, and humans are nothing more than two-legged sheep. Zang Tian travels across and arrives, awakening the Corpse Collector System. Collecting corpses brings explosive rewards and increases cultivation. A white-clad peerless woman throws a heavy fortune, hiring him to break into Demon Capital to collect the corpse for the peerless Empress; that Empress is precisely the obsession of her own previous life. All the way, he slaughters demon kings, guards human passes, swallows immortal disciples, and battles ghostly ancestors, killing his way from a corpse collector to a great emperor suppressing all living beings. The stronger the collected corpse, the more startling the explosive reward; he even collects the high and aloof true immortals altogether!
