At the end of the Ming Dynasty, several masters of Wudang Sect were killed one after another. After many years, the murderer is still a mystery. When the former orphan Geng Yujing, a lay disciple, grew up to be a handsome young man, he met Dongfang Liang who came to compete in martial arts and became close friends. Suddenly, the situation changed again. First, Emperor Taichang died suddenly after taking Wudang Red Pills, and then the new head of Wudang Sect pressed Geng Yujing step by step. In desperation, Geng Yujing left Wudang Mountain and secretly investigated the truth of his parents' murder with the help of "lone thief" Zheng Tiegang and his granddaughter Zheng Qiaoer... In the process of investigating the matter, he met Shaolin monk Huike, the owner of Broken Soul Valley Lu Xiangsheng, Kunlun Ximen Yan and other martial arts people, and finally became a close friend with Nurhaci of Liaodong. As the investigation gradually found a direction and the truth hidden in the past gradually emerged, Geng Yujing finally discovered Nurhaci's ambition to swallow up the Central Plains, and his parents were killed for this. Carrying national hatred and family hatred, Geng Yujing and Dongfang Liang returned to Wudang. The mystery that had been buried for many years was finally revealed, and the traitor was punished as he deserved.
