Rumors in the martial arts world about the reappearance of the Tianyin Sword caused mass killings by all the heroes in the world. The family of Sima Yu, the famous owner of Tianyu Manor, was implicated. The whole family died, leaving only one son alive. In order to avenge the bloody sea, this son changed his name to Qi Bin and worshiped Wudang. However, he was taken away by the devil and fell into the devil's path. Luo Yutian, the third son of the Luo family in Tianya Haijiao Village, has not liked martial arts since he was a child. He is a gentle and refined man, and is proficient in poetry and songs. However, he accidentally learned the Huntian Wuji magic skill of the century-old martial arts legend Xiaoyao Old Man, and also obtained the Tianyin Sword from Xiaoyao Old Man. From then on, he traveled around the world, trying to find the secret behind this matter.
