From all his works, this is probably the best. The art is a masterpiece. At one glance you can guess at once who is the artist if you have read another masterpiece long ago, Ares. =)
That artist's style is unique, it stands out wonderfully. Like the artist from the breaker, they both adapted to the current trend and now the drawings are colored.
Our protagonist is Lee Gwak, a bottom-tier warrior in a certain organization. After a certain setback he became stronger and stronger. However he is quite low-key and at time troubles came at him. Laid-back character but serious when it needs. Through the series, only a handful noticed how strong he is.
The story ended abruptly, this is as if the arc ended and we expect another arc but author announce it doesn't have. A stage where author can pick up anytime if he decides. Anyway the manhwa is axed and if you want the rest of the story, you need to read the novel. However as of now, the novel isn't translated.

I savored every chapter got fond of the main character. Pace was good. But ended too soon.
I would love to see the plot develop

when I first saw it my first thought was what a lame art but somehow I found myself fond of it so far. At least for me the story and pace are fine and after reading for sometime I started to feel the art isn't that bad

Of the four series of him(the others are: Fist Demon of Mount Hua, Legend of the Northern Blade, Memoir of the God of War), this is the worst one in my opinion.
I can't like the pace of the story, neither the plot, and the art is the worst of all(is easily the worst art of the four).
I like cartoons, comics, memes and I read One Punch-Man (the ONE version) without problems, but everyone have some limits.

The art don't improves with time too, for this one sadly only a remake will make me give another try.
