He is a feared "Shura" in the underground world. He bears a blood feud and only destroys in his boxing skills. She is a blind female doctor in the old streets who is as gentle as jade. She has a clear mind and can soothe the deepest anger with her fingertips. After being seriously injured and escaping, he broke into her medicinal world and became her most difficult "patient". She couldn't see that he was covered in blood, but she could "hear" the lone wolf's cry in his heart. When the enemy hijacked the light and forced him to fall back into the dark arena, he realized that the true meaning of Bajiquan was never to kill, but to protect. For her, and for the right path in the world, he was willing to break his fist like a dragon and create a new dawn with her.
