A good Dungeon Maker novel that uses a city for get Mana (DP) from people to expand. Anything is this review is covered in first 3 chapters.

I will get the one issue I have out of the way now: "people are never as forgiving in real life as they are in this novel".

City inside dungeon offers many benefits when you have complete control of the environment.

Lots of girls, but with okay explanation. Rough ex-adventures were told to buy skilled slaves, but not knowing his vision got him girls for reproduction - with minor skills, lolz.


Spoiler:


This is novel that has gotten past the point of a unused harem. Things actual do happen as you get closer to 100 chapters.
