First of all the artwork is amazing, one of the best i've seen in a manhwa. The monster designs especially remind me of Monster Hunter and are great.
The story though isn't incredible, it's a classic revenge tale with an angry protagonist and an hateable villain, it's all competently done but nothing really stands out, there are quite a few twists near the end which are never hinted at before and that could feel like asspulls but nothing major.
The worldbuilding is fine, though it can get confusing at times, the character development and character interactions are there but kept to a minimum which i think is the main flaw of this story along with how one-dimensional and simplistic the commanders of the main villain are.
There are many fights with secondary characters who just aren't interesting because we don't know them well enough or haven't spent enough time with them, so when they have their very emotional ending, i just felt nothing.
There are a few flashbacks which imo are just placed in a weird spot and kill the pacing of the story; also the fights, as beautiful as they are, are just too long and usually don't involve strategy, just i'm stronger than you so i win.
The MC isn't amazing, he has his moments, and he grows as a character by the end, but it really takes a while for him to have heartfelt conversations, i think it could have been done more gradually.
Overall for me it's a 7/10, it's only 83 chapters and the story is done. I think it's worth just for the great artwork and beautiful fights if you are into that, it's well done but nothing ground breaking.
Still better than 99% of the trash out there.
