Three hundred years ago, Lingxi Peak disciples Shen Qingci (who was pregnant with Hongmeng Purple Qi) and Mo Yuan, due to the devil's calculations and the pressure of the right path, came to tragedy in their misunderstandings - Mo Yuan tried to protect her with a "sword through the heart", but her soul was scattered; he sacrificed his half-demon body to go back in time, and reunited with her who was reborn with memories when she first entered the sect.
In this life, the two carry three hundred years of pain and truth, determined to break the fate of "different paths between good and evil", use the power of the same spiritual roots to fight against the prejudices and demonic conspiracies in the world of immortality, rebuild trust in the treacherous path of immortality, and finally become each other's only path.
