Man, this really getting to be one of the best manhwa of all time. Just consistently good every chapter.
I think the only other Korean one that is a contender would be "I'm Really Not the Evil God's Lackey". Usually with stuff like this that go >100ch are slop, but that is absolutely not the case for these two. I mean, there are some of them that go >100ch that I still would rate pretty highly, but those all heavily lean on tried-and-true tropes, and become highly predictable
This one tho has so much soul, and the illustration to back it up. The world, the characters and the story all feel real despite the occasional fantastical elements, and it's so well researched and put together.
Author is an absolute certified G, you can really tell they put a lot of heart into this

and it shows that the illustrators are invested too
