Ye Feng transmigrates into a slave and furnace vessel—on the brink of death, he awakens a Devouring System, turns the tables to slaughter his captors, and escapes with his sister. Returning to the Fox Clan, the Grand Elder attempts to appease the Tiger Clan's fury by surrendering him—but Ye Feng descends into darkness, seizes the Sacred Artifact, slays the Elder, seizes control of the Fox Clan, and declares war on the Tiger Clan. Using guerrilla tactics, he devours mighty foes to evolve into a Six-Tailed Demon Fox.
