Civilized Core book 1

Be careful what you wish for.
You just might find yourself being ripped from everything you know and transported to a different world, with no knowledge about anything there.
As for what Allen wished for that has him in his current predicament well, that isn't something that I wish to spoil here.
Now, as for what to expect in this story, well, you can expect that Allen will find himself transported to a new world, where he becomes a level one dungeon lord and has to learn what that means. At the same time, life back on Earth doesn't stop simply because he's no longer there, as sometimes the ripples of our wishes can reach others as well.
If you like LitRPG, Gamelit, Dungeon Core, Isekai stories and don't mind a fade to black harem being part of the story, then this is likely a story you'll enjoy. If that doesn't sound like you, well, you wouldn't be the first that doesn't fit into that description who decided that they loved it. Just don't expect it to be like anything you've read before as I did it my way!
