Any long or completed recommendations

I'm looking for webtoons/manwha recommendation with any of this plot;
1. Male Mc with no/little romance route (no harem)
2. Transmigrated/reincarnated/regressed to a game/;historically/ martial settings
3. Mc got system that provides perks/level up
4. Dungeons/gate settings
5. Surprisingly, I kinda like martial/clan setting too

If you got albums dedicated to this kind of plots, that would awesome. Will look into it
