Wei Xin, an orphan from Qingshi Village, rescued Nalan Yanran who was being hunted by the devil. After receiving the Yang Jade Pendant to awaken the rare Taoist body, the two of them joined the Qinglian Sword Sect. Wei Xin drew out the Setting Sun Sword and practiced the Nine Setting Sun Styles, knowing the past of his grandfather Qingshan Sword Guard. The two went down the mountain to search for the sect's inheritance, went to the north to find the Heavenly Secret Stone, worked together to severely damage the Blood Shadow Palace, worked together to rebuild the Huanhua Pavilion, and embarked on the path of cultivation in the three realms of immortals and gods.
