I read the entire webtoon from beginning to end. It was mediocre.
The beginning was promising since it hinted at further characterization but completely failed to deliver.
In this webtoon, none of the characters were fleshed out, we got the most bare minimum of backstory (e.g. main character got betrayed by the bad guy, but we only see the moment where he got betrayed, none of the motivations of the characters nor the series of events leading up to the betrayal or anything else, we only see the moment where he gets betrayed and nothing else, so it really is just the absolute bare minimum of backstory). The author spends basically no time fleshing out any of the characters.
To be fair, we do see occasional glimpses of the personalities of the characters through their internal thoughts and actions, but most of these essentially boil down to "is this guy scamming me" or "haha, I'm about to scam this guy". None of the characters feel relatable, they're not humanized and their motivations are not explained.
The final fight was really underwhelming. It was basically:
Bad guy: Was that it? That was disappointing.
MC: Pulls out OP item
Bad guy: Holy shit, your item is so OP. dies in one hit
And that was literally it. That's the end of the story.
The story ends at the point where the final dungeon is about to be entered. We don't know if it is actually cleared or not. It's a shitty cliffhanger ending.
To be fair, it is the mangaka's first serialized webtoon, so maybe I should cut him some slack, but, given the setup, it was very disappointing still. There is basically nothing to enjoy except for the plot. The characters are just not fleshed out and don't feel human, it was not enjoyable to watch the character interactions since it mostly consisted of the MC abusing his sidekick, but his sidekick doesn't even feel human either, he just felt like some one-dimensional sidekick character. Even Return of Mount Hua did this better, the students that the MC abuses actually felt like real humans, whereas in this story the MC's sidekick felt like just a punching bag basically.
Overall I would say it's just not good. There's just the plot and nothing else really. And the plot isn't even that good either. It's just the MC with the OP advantage of knowing the future so grabs all the OP items and wins because he has OP items. That's really the entire story in a nutshell. Everything that happens is within the MC's expectations, basically everyone else is an idiot compared to the MC. I really can't think of anything good about this webtoon tbh...it's completely mediocre in every respect.
