In this world of immortality where heaven is merciless and good and evil intertwine, Yun Wuchen, a genius disciple of the Xuantian Sect, is burdened with the mystery of the reincarnation of the Nine Heavens Sword Immortal and embarks on the path of pursuing Taoism in his past and present lives. Under his cold and frosty sword edge, there is hidden compassion for the common people; behind his aloof figure, there is an endless bond of love with four beauties.
The gentle medical fairy from Ten Thousand Flowers Valley is accompanied by alchemy, the cold and charming saint of Nether Sect is both friend and foe, the frank sword cultivator from Tianjian Sect follows her wholeheartedly, and the wise intelligence leader of Xiaoyao League has hidden feelings. When fragments of the Nine Heavens Sutra appeared in the world, the undercurrent of good and evil forces surged, and Yun Wuchen had to make a choice between sword and love, Tao and righteousness.
Four emotional clues are intertwined with the main line of spiritual cultivation, weaving a magnificent picture of spiritual cultivation. From the Xuantian Sect to the Netherworld Abyss, from the Valley of Ten Thousand Flowers to the Tianjian Peak, various forces are fighting openly and secretly for the ancient scriptures. Little do they know that behind the thousand-year grievances, there is a deeper mystery of heaven and earth hidden.
"The sword reveals the heart, the emotion proves the Tao" - in these troubled times, the legend of a swordsman and the fate of four beauties jointly compose a soul-stirring immortal song. When the Nine Heavens Scripture is finally united, what awaits them is eternal life that transcends reincarnation, or is it a more cruel test of heaven?
