Li Xuanben was a time traveler who lived in seclusion at Jiayun Peak of Longhu Mountain. He lived with the orphan Sang Sang and the down-and-out young man Wen Hua all day long, living a poor but stable life. Fifteen years ago, he was expelled from the imperial family of the Tang Dynasty and has disappeared since then. Li Hanyi, the Snow Moon Sword Immortal from Qingcheng Mountain, came to break off his engagement. The light of his sword pierced the tranquility and revealed his past that had been sealed for many years. At the same time, Wen Hua, who was amputated and lame, accidentally touched the sword marks in the bowl and awakened his peerless swordsmanship inheritance with astonishing talent. Li Xuan originally had no intention of getting involved in the dispute, but as the forces from all sides gradually approached, he had to re-examine his choice. Let's see how this former prince can protect the people around him in this world of two dynasties with the thousands of scrolls in his chest and the invisible sword in his hand, and return to the world.
