Is it wrong to be an Elf in a Dungeon?

Reincarnation, such a wonderful concept! To get reincarnated in an isekai, get an overpowered cheat, become strongest in the world, defeat the evil forces, and eventually gather a harem, however cliche it might be, but our Protagonist wished for it. In the end after dying, he did die and reincarnate into the Royal Family of Elves! A wonderful start, however, he seemingly had no cheat, no system, nothing, his reincarnation was also weird, as after death he just found himself to be reincarnated. There was no Goddess, no Rob, not finding himself in void, just plain reincarnation. Mc didn't despair though, so what if he has no cheats?! He is an Elf; he can make through with his long lifespan and hard work. Then he found that he reincarnated into a very similar world, and dozens of years before the start of the plot. Thus, with a new goal in his lives, he began his venture in this world. As for his goal? He just wants to see what lies beyond the furthest reach of him! Note: Mc won't have a system, and this isn't a translation. Mc might have a harem, maybe even incest, but he isn't the type to go chasing after girls' skirts. Mc won't have any cheat! I mean nothing! Absolutely nothing! He will just use his wits to survive in Danmachi. Don't think Mc will stay weak however, after all he is a gamer, and as a gamer he knows! Grind never stops!!!
