Probably the best in class for action shounen style manwha stories.
Sits among my top with Murim Login and The Legend of the Northern Blade for that genre.
Plot wise, nothing special, korean manwhas tend to repeat the same general formula.
Execution wise though, masterful. Very well paced and thoughtful planning of how a revenge recar would be like.
Art, beautiful and stylstic.
Everything you expect a shounen MC to do, he does it smarter, explains it well and pulls it off more efficientyl, this is also done with antagonists so you can see epic conflicts, something that is tough to pull off.
Well deserved to be at the spot of action manwhas.
