Dragon Tamer Loser? I Raise an Ancient Divine Dragon

In a world where everyone can change professions, the apocalyptic demon god descends upon Blue Star, intent on enslaving and slaughtering all living beings. Humankind gains the ability to change professions, transforming into various roles to combat ferocious beasts and demon gods. Once the mightiest profession, Dragon Tamer now stands as the most useless class since dragons became extinct on Blue Star. Su Yang, having chosen this path, gains the Dragon System—allowing him to summon Chinese dragons. Yet the dragons of this world are merely Western-style lizard dragons, said to be giant lizards bearing a trace of Chinese dragon blood.
