Transmigrated as an abandoned snake clan offspring, Sam Cole barely binds to a system before his birth parents attempt to sacrifice him for his beast core. In this desperate moment, he triggers the Devouring System—gnawing bones, consuming demon beasts, and absorbing spiritual veins to evolve into the Infernal Ancestral Dragon! He counter-attacks and crushes his enemies, unifies the Demon Realm, and even confronts the Demon Realm's world-devouring laws, crossing dimensions to slaughter the demon ancestor himself! He establishes trade between human and demon realms and sets the order for all worlds, yet hidden ancient crises continue to brew—beyond this world, even more terrifying existences lurk. Watch as the useless snake rises, devours the heavens, and seizes control over life and death across all realms!

Human girl Nellie, drunk, stumbles into werewolf king Clifford's territory, has a one-night stand with him, and flees. Five years later, she applies to be his family doctor for her sick son Brady—only to discover her employer is the man from that night. Recognizing her, Clifford relentlessly pursues her while Brady's werewolf blood awakens. Werewolf nobles repeatedly frame Brady as a "cursed child" and try to kill him, but Clifford protects his family. At their wedding, he exposes the conspiracy and proves Brady's pure lineage. Nellie accepts his proposal, Brady gains the pack's acceptance, and the three live happily ever after.
