It's a great read as "fast food" type of manhwa but if you're looking for something deeper it's not for you.
The protagonist is strong and even tho he faces some obstacles most of the time he is the "Top dog".
There is not much to say other than that this is a typical KR webtoon about modern world with RPG elements and dungeon-like intances.
The biggest issue i have with this is how protagonist treats everyone like shit some of those people deserve it some not and some are completely innocent and the protagonist still exploits them. Not to mention some of his actions are hypocritical.
This is not the only issue but biggest for sure (at least to me) and I don't want to make this review look too negative so i will ignore others.
Overall its good read if you're into KR webtoons with RPG elements etc but its by far not perfect.
