It is a story about a young girl that abruptly transmigrated into the body of another young girl (at least in appearance) in another world filled with Magic. She notices that she becomes a Dungeon Master and for a thousand years... she lives a lazy life. However, one day, she lost all of her power and she is kicked out of her Dungeon! And the world's changed that video games level and classes governed the power system of the new world! What will she do as a weak and fragile girl? Will she get her power back? How will she survive in the harsh world?   Author's note: I will update daily if possible and each chapter is around 2,000 words. Gores, Sexual Contents, and Traumatising Contents are limited and I try my best not to write them. However, for the progress of the story, I can't help but write some of them in the latter part of the story. However, don't expect them too much ^_^ English is not my native language, so there might be grammatical errors (maybe a lot), but I'll try to fix them, so constructive critiques will be appreciated (^_^)
