The story unfolds in 2225, an era of spiritual rejuvenation where supreme martial prowess reigns. As abyss rifts tear through Earth, monstrous beasts ravage the land, and humanity's fate hinges on innate talents awakened at age eighteen. Chen Fei, a youth from Cangwu City, relives the day his S-class talent ""Skyfeather Archer"" was stolen by Zheng heir Yunjie—a theft that once led to his bitter death and the demise of his loved ones. Reborn with vengeance, Chen Fei awakens the unique SSS-class talent ""Celestial of All Laws"" in an abandoned Taoist temple, gaining the Dao Self-Proof System that unlocks supreme divine arts through adversity. He surges in power, crushing underground fight rings and dismantling the Zheng Clan's talent-trafficking rings, rescuing stolen prodigies while exposing their crimes of resource monopoly and forced talent extraction. At the national martial exam, Chen Fei secures an SSS rank with absolute dominance. On the arena stage, he shreds Zheng Yunjie's ill-gotten wings, restores the stolen talent, and unveils the Zheng Clan's atrocities to the world. To save kidnapped heroine Mu Xinglan, he storms the Zheng Manor, obliterates their human-beast fusion lab, and ascends to Earthly Realm cultivation in a blood-soaked reckoning. When the Formless Demon God unleashes a global beast tide to sacrifice Earth, Chen Fei stands alone against the horde, saving humanity—only to be slandered as a demon and betrayed. Disillusioned yet resolute, he feigns allegiance to the Demon God to destroy its soul core. In a final sacrifice, demon leader Tu Shanyue immolates her nine-tailed life essence to protect him. Consumed by grief, Chen Fei's hair whitens and tears turn to blood as his soul rages. He annihilates the Demon God with the Nine Heavens Thunder Annihilation, shattering his own dao foundation to shield mankind. Upholding his convictions in despair, he proves the Great Dao and is bestowed the title Celestial of All Laws by the Dao Ancestor. After healing, he retreats to the mountains with Mu Xinglan, embracing peace.
