The World's Strongest Regime

After ten years of secluded training, Jin-gwon descends from the mountain to avenge his father, only to find that the world he knew has disappeared. The Murim is gone, replaced by a fantasy era governed by magical skills and systems. Wearing a ragged martial arts uniform and armed only with his fists, Jin-gwon seems like a relic in a world that has cast martial arts aside. But the age may have changed without changing what true strength means, and he is ready to challenge this new reality with a single devastating punch.
