Is it worth reading? I have mixed feelings about the concept

Yes! It’s really good

HELL yessss honestly this genre is so under appreciated! It’s really well done, you won’t regret it ε=ε=(ノ≧∇≦)ノ

I'm not usually into fantasy at all but it's really good, unpredictable, compelling and original. I'd definitely recommend it.

It's very good, You may also like Solo Leveling

Thank you to everyone who answered, I will read it when I have time (๑•ㅂ•)و✧

I've already read it up to the latest chapter, it's one of my favourites actually

Then I think that you will like this as well. Ranker who lives a second time, Trash of the Counts family, Omniscient readers viewpoint, The Beginning after the end are also great. Hit me up for more recommendations If you want to, I really like this genre so I was searching for more manga's like Solo Leveling some time ago
