Her husband falls for someone else, falling in love with the genius sword cultivator heroine. Lin Miao is poisoned with a deadly toxin, her four-element mixed spiritual root is completely devoured, and she is thrown out of the marquis's estate. In the end, she becomes a demonic cultivator and dies miserably in the street. Hounded by everyone, the demonic cultivator Lin Miao turns around and throws herself into the arms of the Great Zhou dynasty's number one demonic sect, the Xuanxing Sect. She thinks she'll become the beloved darling of the villains, but who could have guessed... Eldest Senior Brother: Little Junior Sister, stop absorbing! You're draining all the human race's fortune! Second Senior Brother: Everyone says my Ten Thousand Souls Banner is evil. Then I met Little Junior Sister, and I admit I'm the good one. Third Senior Sister: Let Little Junior Sister take over as the great demon king. Fourth Senior Sister: Little Junior Sister and I are mowing down our enemies. She does the killing, and I do the cackling. Ever since joining the Xuanxing Sect, Lin Miao has become so wicked she no longer knows heaven from earth. You dare stand in the way of my search for opportunities? I'll mow you down. You dare insult the reputation of my Xuanxing Sect? I'll mow you down. I'll mow them all down, until no one in the world dares call themselves an immortal!
