Ling Shuangyue, the number one saint in the Tianyan Continent, was cut off from her innate Taoist bones by her most trusted senior sister and her fiancé on the eve of her wedding to a Taoist monk, and was thrown into the abyss of evil. Everyone thought she had turned into dust, but they didn't know that she was at the bottom of the abyss, accidentally fused with the forbidden source of chaos that even ancient immortals and demons were afraid of - Chaos Ancestral Qi. Once she was out of trouble, she was no longer the saint who cared about the common people, but the vengeful demon who returned from the Nine Netherworld. With a butcher knife in her hand and hell in her heart, she vowed to let the souls of all betrayers perish in chaos forever. When the former fairy transformed into Shura, a bloody storm swept through the three realms and began.
