Twenty years ago, the Jingtian Sect was instigated by the elders of the evil Lurong tribe and became enemies with the Wulin. It was besieged by the four major Wulin families and Shushan. The leader Jiang Aotian sent away his pregnant wife Ouyang Qian, and was suppressed in a forbidden cave by Shushan. Twenty years later, after Jiang Yifan, the son of Aotian, met Tang Ruoyun, who was suffering from a strange disease, and Shushan disciples Xiaoman and Longyu, the news that he was the son of the leader of the Jingtian Sect, Jiang Aotian, spread like wildfire. He was regarded as Jiang Aotian's evil son and became the target of hunting by various families. Yifan had a pure heart, adhered to the right path, endured the strange eyes of the world, passed many tests, worshipped Shushan, practiced hard, and made rapid progress. However, he did not dare to face his feelings with Tang Ruoyun because of his life experience. When he was troubled, he found that Ruoyun was suffering from a terminal illness and his life was in danger. Yifan went through untold hardships and rescued his father Jiang Aotian, but he was unable to save Ruoyun. Although he was heartbroken, he still insisted on justice in his heart, and did not resist the instigation of the villains. He won the trust of all the martial arts factions with his superb martial arts and strong personality charm. In the end, the father and son joined forces to defeat the evil elder, exposed his conspiracy to subvert the martial arts world, and maintained the peace of the rivers and lakes.
