Level Up to Gain Talents? But I'm a Villager by Profession

(Also known as Dungeon Sequence: From Laid-Back Player to Godslayer) [Another World + Dungeon Maze + Adventure and Exploration + System + Slow Burn] After drawing a useless class, he was abandoned by the classmates who had transmigrated to another world with him. He left the party and spent a year doing nothing, only to unexpectedly level up and draw a rare [Legendary] talent. How could he make use of it? Just then, one strange incident after another began to unfold, and the world seemed to be changing. Mysterious ancient gods watched it all. New gods were about to rise, and everything was merely a pawn in their game. A year later, Song Kai set out once more, only to discover that the journey was far more complicated than he had imagined. (No harem or romance with multiple women. A leveling-up story with a dark, bizarre edge.)
