Deep in Yandang Mountain lives a forest ranger. Every day he chops wood and forges swords, yet he never uses one to kill, because the iron blade in his hands is merely a fragment he picked up from a battlefield. Ten years ago, he was Su Jinghong, a swordsman who roamed the martial world. Ten years later, he is an anonymous woodcutter at the foot of Yandang Mountain. Then a band of men in black appeared, burning down his hut and awakening his slumbering memories. His broken blade left its scabbard, and a dragon’s roar rang out. Only then did he understand: some debts cannot be evaded, and some duties must be fulfilled. From that day on, Yandang Mountain lost a forest ranger, and the martial world gained a hero bearing a broken blade.
