In a single night, the entire Lu clan, a family of scholars in Qingyun City, is wiped out. The only survivor is the young Lu Xuan, who carries his family’s ancestral jade pendant. Trapped at the bottom of a dry well, he encounters the ancient divine sword “Nine Heavens.” Its sword spirit awakens and teaches him an unrivaled body-tempering method, setting him on a bloody path to immortality.
From an ordinary boy who tempers his body to one who establishes his foundation and seeks the Way, from the formation of his Golden Core to taking revenge with his Nascent Soul, Lu Xuan wields the ancient Nine Heavens sword and cultivates a Chaos Sword Body despite possessing meager talent deemed a “useless spiritual root.” He makes his mark in the battle of the human world’s greatest prodigies across a hundred provinces and turns the tide amid the catastrophe between the righteous and demonic paths. Yet the final chapter of his revenge reveals an even greater conspiracy: his family’s massacre is tied to the mystery of an ancient Immortal Emperor’s fall, while the mastermind, the Nine Nether Sect, schemes to connect the three realms and restart the age.
Ascending to the Immortal Realm is no end. From a lowly Earth Immortal scorned by all at the Immortalization Pool to the master of the Star Alliance and an Immortal Emperor whose sword sweeps across the Eight Directions, Lu Xuan navigates among the Immortal Realm’s powerhouses, the demon realm’s holy clans, and the demon world’s exalted emperors. He gradually comes to understand that he is the reincarnation of the undying sword intent of the ancient Lingxiao Immortal Emperor. The traitor of old has become an “evil thought” that devours the Heavenly Dao, seeking to treat all things as mere dogs and preserve an eternal, lifeless order.
The final battle erupts at the “Ruin of Eternity,” at the end of time and space. To destroy the evil thought of the Heavenly Dao and shatter the chains of fear, Lu Xuan burns away everything, merging with the ancient sword and uniting his past and present lives with the faith of all living beings to unleash a sword strike that transcends the age. A new Heavenly Dao is born, the old body scatters, and the legend seems to have come to an end…
