Shen Lingxi, a genius disciple of the Qingyun Sect, is framed through a conspiracy between her senior sister, Su Qingyao, and her fiancé, Ling Zhao. They steal her sect's inheritance token, seal her meridians after falsely accusing her, and exile her to the perilous Guixu Secret Realm. In truth, she is a descendant of the ancient guardians of the spiritual veins, and the seal has not destroyed her foundation. In the secret realm, she encounters Mo Heng, a reclusive guardian of the spiritual veins. With his help, she discovers opportunities to gradually unlock her powers and gathers evidence to expose the conspiracy. After clearing her name, she is hunted by mysterious forces coveting the bloodline of the spiritual vein guardians. Eventually, Shen Lingxi finds her mother, who has been trapped in the secret realm, and comes to understand the true meaning of protecting the spiritual veins and maintaining balance. Together with her companions, she takes on the mission of safeguarding the world's spiritual veins.
