World’s Strongest Straight Punch

To avenge his father, Jin-gwon spent ten grueling years in secluded training. But when he finally descends the mountain, what awaits him aren't his sworn enemies—it's a completely unrecognizable world.

The Murim has vanished, replaced by a fantasy era ruled by magical 'skills' and 'systems'.

Armed with nothing but his ragged martial arts uniform and his bare fists, Jin-gwon looks like a relic of the past. But just because the era has changed, doesn't mean the true essence of strength has!

In a world that has discarded martial arts as obsolete, Jin-gwon is about to turn this new fantasy reality upside down with a single, devastating straight punch!
