Global Beast Taming: From the Start, I Have an Abyssal Kun

Good-for-nothing Lu Chen, an F-rank nobody, awakens an against-heaven Devouring System. A koi he was admiring evolves into an abyssal leviathan that devours heaven and earth! When the Frost Dragon Maiden burns through her life to break a curse and the Holy Light Elf heals all things, he rides a Kunpeng to shatter the chains of class, devouring ferocious beasts, planets, and even gods! "You say this is an S-rank dragon? Sorry, my koi eats those for breakfast!" From the slums to the pinnacle of the universe, the throne of the Beast-Taming Era is forged in flesh and blood!
