The third son of Abandoned Sword Villa, Shen Zhenyi, came into possession of the long-lost martial arts manuscript "Wan Zang Sword Sutra" in the world of Jiuyou, gaining notoriety in the martial arts community. While battling the Demon Sect's leader, Minyiren, over the sword's ownership, Shen Zhenyi vanished without a trace. After a year, the Abandoned Sword Villa reopened, with Shen Zhenyi personally instructing disciples in the "Wan Zang Sword Sutra," causing quite a stir. By chance, Chu Huoluo, a female disciple from the Lieyang Mansion, became Shen Zhenyi's apprentice. As they delved deeper into the manuscript, they unknowingly fell into imminent danger, tied to an ancient legend called "Zhanyue Feixian." As they uncovered the final scheme, it became evident that everything pointed towards this legend.
