Almost at the season 1 finish line (currently at ch. 104) and the only thing I dislike about this manhwa is this: considering the main character is, well, overpowered, most villains lacked the development needed to make them feel scary. At no point did I feel like the main character was in real danger and although it was super satisfying to see him absolutely destroy all in his path, and smirk with arrogance, it was always the expected outcome.
Leaving that aside, if at any point you played world of warcraft or dark souls and liked it, then this manhwa is for you.
