Ji Jin, the abandoned sword slave, was abandoned in the abandoned sword tomb for thirty years. A lightning strike awakened the ancient sword bones. With one sword strike, all nine peaks of the sect fell to their knees. Liu Wushuang, the daughter of the leader of the Sword Sect, is suffering from a bone-eating poison and is in urgent need of sword bones to survive, but she does not know that she is the real culprit who killed her master and destroyed her sect. The iron-hearted old slave painted a picture of the sword with blood, the white-bone harp girl broke the string to attract the soul, Yun Lang wanted to refine the sword bones into a puppet, and the red owl snatched the bones from the sky. The sword bone is not a weapon, but a curse, a legacy, and the ancestor's undead soul. When Ji Jin wielded his sword to ask the sky, what the entire sect was kneeling on was the orthodoxy that he had buried with his own hands.
