The Hwan Continent trembles at his name, a legacy carved in the blood and sweat of countless battles. He stands alone, the "supreme Martial Emperor," his power absolute, his martial arts honed to an impossible edge. But even after unifying the entire martial world, after reaching the pinnacle of might, a chilling void echoes in his heart. A yearning for family, for something lost, gnaws at his soul. So, he gambles, tearing through the fabric of reality with forbidden sorcery, hoping to bridge the dimensions and find what he left behind.

Suhyeok, the peak of his former world, suddenly jolts awake not to his familiar cultivation chambers, but to the blinding white sterile walls of a modern hospital. Five years. That's how long he's been comatose, his family crushed under mounting bills while he slept. And then it hits – a holographic system window flashing before his eyes, a mocking symbol of betrayal from that "Black Sage" who promised a way home. With his family's very survival on the line, how does a literal martial god pay off debts and protect them in a world where leveling up is the only path?
