The protagonist, who died in an accident, is forced to reincarnate into a parallel world without any choice. That world is one where the First World War did not happen due to the emergence of dungeons.

The protagonist, who reincarnated into a world where anyone can be given a skill, dives into the dungeons with the skill he was given.

“This skill is too problematic, I have no choice but to hide it…”

The skill that the protagonist was given was a non-combat one. With his unique constitution to supplement it, the protagonist sets out to conquer the dungeons.
