I think you need to read this once in your life

But no unnecessary lolis only serious action https://mangadex.org/title/13871/dungeon-meshi 
One of my favorites. It's slice of life at first with cooking and light story in dungeon settings, but plot and action will thicken later in chap 20 or something and more serious and sometimes you might say 'holy shit' too. Highly recommended https://mangadex.org/title/16482/made-in-abyss 
This one has great world building  https://mangadex.org/title/10271/ballroom-e-youkoso 
My fav dancing mangaa, art is good and pleasing to read https://mangadex.org/title/20523/beastars 
https://mangadex.org/title/21395/the-fable
 Cool & entertaining. Story about assassin taking a break and try to lead a normal life https://mangadex.org/title/2379/dorohedoro 
One of my fav too. Art is a bit unique but the story it self is pretty good. The other works is pretty awesome too but still have a little chapter and too bad its monthly release https://mangadex.org/title/13414/no-guns-life
