"The Insect King's Dungeon Creation Chronicle" or "My Dungeon Creation Record as the Insect King"

I was suddenly reincarnated into another world and was determined to enjoy this new life, but something unfortunate happened. The form I was reincarnated into was an insect. Ugh, this is the worst. There's no way I can create a harem surrounded by elf older sisters and cat-eared beautiful girls like this. Furthermore, when I tried to build a residence, it somehow turned into a dungeon-like place, and some sketchy-looking people started coming around. I'm fed up with this. If that's how it's going to be, I'll create a dungeon that no one would dare approach and shut myself away in it.
