Half decent story, but at some point both the translator and artist changed. The writing is a bit odd at points, and around chapter 40 to 60 the characters become 80 percent chin.

Wow. Just...wow. This is the kind of story telling that needs outrageously powerful, colorful, bursting at the seams art to mask the horrible writing and distract from it.

It's so bad that it's obviously not the translator who's making it so choppy, clunky and unbearably boring. This is what the original probably reads like.

I've read absolutely wonderful stuff with ugly art but it wasn't noticeable anymore because the storytelling was so captivating. This...this cannot get away with both art and story being simultaneously this painful to struggle through.

I wanted to like this so much. I usually love all of these kinds of trashy, forgettable stories. I actively seek them out but...this one. This one? Oh man, this ain't it.

Dropped.

I agree with everything @PZcolo said but just to clarify something, the world the MC came from seems like a very normal modern world (Just like Solo Leveling, modern world that got magic and superpowers because of gates or system or whatever)

Story, characters, dialogues all are nonsense, I'm guessing part of it might be the translation, but the main reason seems to be how the author seems to have taken all the information that bridges the events that happen in the manhwa and threw them leaving a disconnected mess as a result. Let's also add annoying characters like Ian (the butler) and lame humor that disrupts the story.
An example, he's the hero of the previous world, a fantasy world, yet he keeps talking about modern age things, like cola, refrigerators, and the like, it seems before he was a hero he was summoned or isekied to be the hero, yet this is not even mentioned, it might also be, that it's a modern fantasy world, either way, we don't know. Or how he shows his powers to others because he wants to drink coke when he's been trying since birth to hide them. And something similar happens with every aspect of the story, the MC is ruthless some times, benevolent others, intelligent then dumb, decisive them not and so on.
Also, the art is not particularly good, the fights are rather lame.
It's in short a mess, maybe the novel is worth it but this is not worth the time imo.
