One of my daily reads on raw sites(see Eternal Angel's post of the name). It's a bit OP but not as much as most dungeon novels. Skip if you don't want the world view 'spoiled', but I won't cover storyline spoilers other than it appears to be a single female love interest for those worried about harems. Basically the world (implied to be a flat circle) he's living in has a 'god' called the Mist. That god rescues fragments of broken worlds from the void, transforms them into dungeons and explorers basically beat the fragment into submission. All the people in the lower level dungeons are 'stored' and copies fight the explorers. It's not clear yet about higher level dungeons. There's a lot more details but that's the basic idea.
loved it. the plot is easy and fun to read. the MC is not OP. But his strong enough to stand his ground. the story is a bit slow but love the fighting scenes. MC is cool headed and a bit navie maybe his still new. His fighting skills are more crowed control and support type which is rare to most MC fighting style.
