The class is summoned to become heroes and save a country from destruction, students of these class are blessed with cheat specs and cool job class, but that’s not the case with Hajime, his job class is a “Synergist” and his stats are very normal (mediocre). “Synergist”, to put it in another word is just artisan class. Being the weakest, he then falls to the depth of the abyss when he and his classmates are exploring a dungeon. What did he find in the depth of the abyss and can he survive?
