I completely agree with you,i also believe that the MC became too OP,i just didn't feel the excitement in recent Sung jin woo battles like i used to before because i know that he's just gonna own them anyway(and quite easily)
Now the only guys stronger than the s class are those national level hunters and i'm pretty sure that even they are weaklings compared to jin woo now.
I feel like there is no improvement anymore cause there is no one who can be a challenge for him now. I also lost the addiction to this webtoon but i still like it though,and art is godly and MC is so hot and cool
Yeah that's understandable. The thrill of Jinwoo possibly losing and having to fight for his life, doesn't exist anymore. The author is relying on the shock value of the action scenes to keep the thrill going. Like I know Jinwoo is going to win, but the fight looks so cool, specifically with the detailed art. That sort of reliance does wear off after a while.
I promise, if you just wait for the story to develop further, the excitement will be back full force. I don't want to spoil too much, but there are still a lot of enemies in this universe that are much stronger than what Jin-Woo is now. The reason why he is becoming so op recently is because he needs to catch up to the strength of the "final bosses". It's gonna be epic.

this manhwa really good, art is nice, mc such a hotie and cool. But, i feeling like lacking something because... like was he just too OP and i dont feel any surprise anymore? Like i enjoy its really when i first read this but i feel like its not addictive recently? Maybe i wait my ass out for each chap so feel a little lacking something :/ its still a good manhwa and cool anyway
