Mechanical God Emperor - Chapter 9 – Capturing the Black Rock Town

Is it wrong to face the perils of Dungeon alone, in a single-member guild blessed by a failed goddess? Maybe.

Is it wrong to dream of playing hero to hapless maidens in Dungeon? Maybe not. After one misguided adventure, Bell quickly discovers that anything can happen in the labyrinth-even chance encounters with beautiful women.

The hearse with the weird odor slowed to a stop before the entrance. The sound of pebbles could be heard bouncing on the ceiling. There were footsteps coming from the corridor, and there seemed to be someone sawing next door.

Wet footsteps started to surface one after another on the floor.
