The blind girl Su Tang, who was regarded as a waste by the Su family, awakened to regain her sight at the critical moment of life and death. She discovers that she is the reincarnation of the saint girl of the Lu family thousands of years ago, and she shoulders the mission of guarding Xuanmen. Rong Siheng, the guardian of the heavenly clan, has always been by her side across thousands of reincarnations. The two join hands to fight against the Black Mandala organization and expose Lu Hanchuan's century-old conspiracy to betray the Lu family. Su Tang used the power of his blood to rescue the imprisoned Lu family heroes, completely wipe out the remaining forces of the Black Mandala, and completely clear up the Su family. In the end, she was canonized as the number one contemporary person at the Xuanmen Grand Ceremony, fulfilling the thousand-year promise with Rong Siheng and opening a new chapter.
