Once a legendary undefeated pugilist who dominated every underground ring, Lin Feng fell from the peak of his life overnight. Betrayed by his most trusted brothers and framed by greedy rivals for illegal fighting and assault, he lost everything—his reputation, his career, his family’s peace, and even his right to stand on the boxing stage. To make matters worse, he was brutally injured in a vicious trap, leaving his fists crippled and forced to bear the scorn and humiliation of the entire industry. The once invincible fist king became a worthless loser abandoned by the world. For years, Lin Feng chose to lie low and endure all the insults in silence. He pretended to be a mediocre, powerless nobody, letting others mock his downfall and trample on his dignity. Everyone believed his fighting days were over, and that he would spend his life in despair and defeat. Yet no one knew that beneath his humble and weak appearance, his fighting will never faded, and his iron fists were recovering in secret. He endured all hardships solely for one purpose—to avenge the injustice he suffered and redeem his ruined honor. When underground boxing turmoil sweeps the city and his enemies grow rampant in power, Lin Feng finally steps out of the shadows. He returns to the brutal fighting ring, not for fame or fortune, but to settle every bloody score with his own fists. Step by step, he crushes arrogant rivals, exposes the ugly truth of the old conspiracy, and defeats all those who once betrayed and humiliated him. In the name of his fist, he rewrites his legend, washes away all humiliation, and proves to the whole world that a true fighter never falls—he only rises stronger from the abyss.
