Having transmigrated to another world, Draig is born in a black‑dragon nest. Wingless from birth, he is regarded as a defective outcast by his mother Valguria and suffers constant bullying from his pure‑blood kin. On the brink of death, he activates a devour‑and‑evolve system and unlocks the Leviathan bloodline, gaining power by consuming everything he encounters.
He hunts ferocious beasts in the perilous swamp and unlocks a host of formidable talents. Later, he takes human form as the youth Nero and ventures into the human capital. He wins over the witch Lilith, seizes control of the black‑market territory, and forces pure‑blood dragon heir Evelyn to sign a master‑servant contract.
The Dragon‑Slayer Guild and the Holy Church army launch successive crackdowns. Amid fierce combat, the ferocious dragon power inside Draig runs completely wild. His aura alerts Valguria, who dwells deep in the Abyss Dragon Nest. Faced with the destructive avatar of his mother projected across thousands of miles, will Draig, blessed with Leviathan’s power, manage to defeat this terrifying foe?
