In the expansive Jiang Dynasty, swordsmanship culture has been inherited for millennia, with its practitioners taking pride in their craft. Yet, attaining the pinnacle, the "Sword God Realm," remains a rare achievement. More than ten years ago, the formerly mighty Wuji Sword God was gravely wounded by the Changsheng Sword God's schemes, compelling him to withdraw into mountain seclusion, removed from worldly matters. Now, Zhan Yibai, the sole disciple of the Wuji Sword God, has reached adulthood, and the moment has come for him to begin the training journey agreed upon by master and student. Prior to leaving, to bolster Zhan Yibai's self-defense capabilities, the Wuji Sword God gave him his personal sword and directed him to quickly attain the Sword God realm. Fresh to the secular world, Zhan Yibai makes friends with Jiang Mingyue, the dynasty's princess, and Li Kuang, the second son of the Prince of Zhennan. Eager to grow swiftly, he and his companions enter the "Ancient Dynasty Ruins" trial, setting off on a notable journey.
