Born with a mortal bone constitution, Lin Che has spent three years cultivating in vain, reaching only the third layer of Qi Refining. At the outer sect of Qinglan Sect, he has tasted every cruelty of the world. Only after stumbling into an ancient ruin in a desperate situation does he realize that this so-called "mortal bone" is actually the result of a meridian-locking curse planted in him. The Dust-Defying Pearl enters his body, awakening the Ninefold Sword Scripture. He tempers his sword heart with his essence and blood, and uses the pearl to break his shackles.
At the sect's minor competition, the mortal bone draws its sword and shocks everyone. Amid the turmoil of the inner sect, he meets Xiao Yi, a gifted formation master, and Man Shan, a warrior of the barbarian tribes, and forges a bond of life and death with them. At the commandery competition, his sword overwhelms all rivals, catching the attention of the cool and aloof fairy Chu Yao.
From Cangwu Commandery to the borderlands of the Spirit Realm, from the Golden Core stage to the Void Refining stage, he traverses secret realms and slays demons and evil beings. Yet when he reaches the summit, he discovers an even greater mystery: behind the meridian-locking curse lies a shocking game of wits concerning the survival of the Three Realms. The secret of the reincarnated Creator God slowly emerges, and the fate carried by the Dust-Defying Pearl weighs like a mountain.
As the armies of the Demon Realm bear down and undercurrents surge within Tianyan Sect, Lin Che stands with sword in hand. Behind him are friends who share life and death with him; in his heart lies the weight of countless lives. This sword will cleave open not only fate, but also the eternal night shrouding the Three Realms.
Even a mortal bone can defy the heavens, and a sword heart will pierce the nine skies. This is a long road to godhood paved with passion, an unyielding struggle in which a humble mortal defies a calamity that threatens the world.
