The Ancestor of Magic

[Thousand-year-old Father Immortal Lord x Ancient Spiritual Little Demon King] Yun Xi, the ancestor of evil arts, has a bad reputation that scares the celestial beings. Treason against the sect, killing fellow practitioners, refining corpses to control ghosts, the crimes are too numerous to list. The shocking murder finally aroused the anger of the nine immortal sects. They jointly kowtowed to the sword of Lingxiao Sword Lord and vowed to kill this beast. In the demon-slaying formation, everything was dead silent. Lingxiao Sword Master's long sword was cold against her throat, and his voice sounded like Han Yuan: "Follow me, okay?" But she suddenly smiled, her eyes reflecting the broken light of the sky, as if she had been waiting for this moment for too long. He suddenly raised his head, and warm lips touched the corner of his cold mouth, like a sigh, like falling: "... Unwilling." Before he finished speaking, his slender neck reached the edge of the sword—— Blood splattered on his white clothes, and his soul was scattered. A hundred years after her death, Yun Xi was content to be a lonely soul, but unexpectedly she was reborn as a strange girl of fifteen or sixteen years old. In this life, I just want to hide my traces, but troubles come one after another: a strange groom, a headless female corpse, a dead body in the medicine valley... Behind every strange thing, there is a faint connection to the murder a hundred years ago. This time, she no longer walks alone. There is also a rigid and taciturn old man by his side, walking all the way, step by step approaching the truth buried by time.
