Haoxuan, an ordinary servant, accidentally awakens the "sword bone" in his palm, formed from the remains of an ancient Sword God, and is drawn into the whirlpool of Qingyun Sect's schemes. Framed and hunted, he encounters a reclusive master in a desperate situation and receives sword techniques. He tempers his sword bone with demon cores, breaks free of his shackles in the prison for the crippled, and rises from the bottom step by step, uncovering the secrets of the sect elders stealing sword manuals and practicing demonic arts.
After leaving Qingyun Sect, the winds of change sweep across the Nine Provinces once more. Carrying his sword bone, he sets out on a journey of cultivation. In Blackwind City, he meets the Demon Cult's Holy Maiden, then navigates the power struggles among the three great sects. To lift the "sword malice" curse that comes with his sword bone, he embarks on a quest to find the Sword-Washing Pool and the seven keys to divine weapons. From the Misty Marshes to the Dragon Palace in the deep sea, from secret-realm expeditions to betrayal by his companions, he fuses his own will with the power of his sword bone amid blood and fire, creating a "new sword path" and turning the sword malice to his own use.
When the demon army invades and Heaven's backlash descends, he reaches the state of "winning with no sword over having a sword." He leads the alliance in a decisive battle against the fallen immortals at the Sky-Piercing Tower and uses himself as a sword to sever the connection to the demons from beyond the realms. But Heaven's backlash strikes, and his body shatters...
