There may be small spoilers (This is my first review here)

The story focuses primarily on Jin-Woo becoming an overpowered hunter rpg style, it may sound boring, but it actually unfolds in an interesting way. Other than that there also seems to be a mystery about what the system is and why it gave him the ability to keep going up.

Combat is fun and sometimes they use a few strategies, so they are not boring.

The art is great, the background, the characters and especially the enemies look fantastic.

The characters are the least remarkable, most are impressed by Jin-Woo's power or underestimate it, they have almost no deep development, yet most are nice, like Yoo Jin-Ho. The main character is intelligent and changes slightly as he levels up, becoming perhaps a little conceited and cold, which is a little edgy, adding that in most of the panels you only see one eye shining in blue, something cringey but passable.

In spite of having several weak points, when you start reading it you start getting more and more interested in everything that happens and how it happens, or at least that was my case.

(Spoiler) Actually the only time I felt some boredom was in the fight against the super evolved ant.

In short, it's definitely not a masterpiece, but the fights, the art, the way in which the story and the protagonist's overpower are handled, make it an outstanding zero to hero series. If you like rpg, you don't mind the overpower and you don't mind the edgy part of the protagonist, I think you can enjoy it.
