While working at a pet shop, Lin Xiao unexpectedly awakened a forbidden bloodline. His beast could devour anything and evolve: a sand crystal core awakened sand manipulation, dark energy granted control over shadow clones, and it could even fuse the powers of light and darkness! But every time it devoured something, Lin Xiao came one step closer to the abyss, because the prophecy of an ancient altar was coming true: "The ninety-ninth vessel shall become the new Lord of the Abyss!"
The Dragon Scale Organization wanted to capture him for experiments, the Tomb Keepers hunted him with bronze compasses, while the Abyssal Council extended an offer of alliance. When Lin Xiao entered a secret realm with his mutated Crimson-Scaled Dragon Lizard, every Beast Tamer trembled. This massive beast, its scales gleaming dark gold, could spew flames that scorched the heavens and freeze space and time!
