Synopsis

Lee Changseon enters a challenging dungeon after undergoing a giant transformation, facing an initial gatekeeper named Gustav. He struggles to control his powerful 'hellfire' ability, which has become more volatile due to his transformation and mixed with 'pitch black darkness'. Gustav, a seemingly muscle-bound warrior, unexpectedly engages Changseon in combat and then offers bizarre training advice focused solely on physical strength and muscle development for controlling the fire. Meanwhile, the chapter hints at other travelers who have passed through the same trials, raising the stakes for Changseon's journey to conquer the dungeon.
