It was a dark age in the martial arts world. Since the great heroes such as Li Xunhuan retired one after another, there was no one to succeed the righteous path, and the five evil forces were rampant. Lu Nanren was betrayed by his fellow disciples for fighting for the secret sword of Piaoxiang, and almost died. Fortunately, he was rescued by the mysterious master Lao Li and brought back to Juxian Villa, the hiding place of the righteous path. Lao Li saw that Lu Nanren's conscience was not extinguished, and cultivated him to become the right-hand man of the new generation of righteous leader Zhong Jing, but he could not get the trust of the young owner Sun Min because of his evil deeds. Lu Nanren was still concerned about the evil path, but because he had been with Sun Min and others for a long time, he was gradually influenced by them and began to change his ways. On the other hand, the leader of Tianzheng Sect learned of Lu Nanren's whereabouts and tried every means to induce Lu Nanren to become his pawn, wanting to destroy Juxian Villa in one fell swoop. Lu Nanren wanted to stay out of it, but because he couldn't bear to give up his feelings for Sun Min and Lao Li, he resolutely took action.
