System sponsored dungeon

A dungeon core gets placed in an unreachable location and ends up making a deal with the system that governs the whole universe she has landed herself into. In all the light novels she read before she died no one had ever done that before. That has to mean good things for her right? She sure hopes it doesn't make things worst at least.  The second main character get's introduced in chapter six. Dungeon building until chapter thirteen. Second character lands in the dungeon in chapter twenty. First time posting one of the stories I've written. I've always wanted to write books. I am writing this on my kindle so if you see any mistakes please forgive me. I will try to post on Mondays and Thursdays. Thanks for giving me a shot. Please if you leave a review don't be a jerk. Please and thank you. Don't post this story somewhere else. The photo is an AI rendering of Katherine.
