Can't I just build things in a dungeon?

A Danmachi(Is it wrong to pick up girls in a dungeon?) Self-insert Fanfic

The story follows me, the author, as I mysteriously end up in the city of Orario ten years before the begining of the story. Follow me as I try to figure things out and actually enjoy my life as an adventurer. Where the story actually focuses around exploring the dungeon rather than all the problems that happen around it. Canon will be thrown to the wind and in classic self-insert fashion the insert tries to save everyone.

But this time they fail.
