I Become the Only Dragonslayer

As dragons ravage the continent, Ren and Alia are captured after Ren unleashes a mysterious power on the battlefield. Salvak throws him into the arena, where he bonds with the stone golem Rock and awakens his dragon-rider bloodline amid life-and-death combat. Alia follows the Elf Queen north for aid and uncovers Ren's origins. Noticed for his explosive power, Ren is forced into a dragon-slaying squad.
