Su Wanyue was born with a sword bone. She was supposed to be a proud daughter of heaven, but her family regarded her as unlucky and forcibly sealed her qualifications, making her a trash that everyone could bully. With a marriage contract, she was forced to take the place of her concubine and marry the young master of Xuantian Sect, who was about to die soon. She thought this was the bottom of her destiny, but she didn't expect there would be a deeper hell. On the night of the wedding, the groom died suddenly on the spot. She was falsely accused of being the bane of Croft, and amidst the cold eyes and ridicule of everyone, she was locked alive in an ice coffin and buried with her "husband" whom she had never met. After a hundred years of confinement, the endless loneliness and coldness eroded every inch of her flesh and blood. Everyone thought that she had turned into withered bones long ago, and the Su family and Xuantian Sect had long forgotten about her. Until one day a hundred years later, the ice coffin in the sect's forbidden area exploded, and a woman in plain clothes stepped out of the sky filled with ice fragments! She did not die, but was a blessing in disguise. The sealed sword bone awakened in the extreme cold, and merged with the pure sword intention remaining in the dying body, giving birth to a unique ice soul sword baby in her belly! The enemies back then are now high-ranking sect elders and family ancestors. They looked at the "old friend" in front of them, whose appearance had not changed but whose breath was bitingly cold, with horror on their faces. Ancestor of the Su family: "Monster, monster! Aren't you dead a long time ago?" Xuantian Sect's leader: "Bold witch, trespassing into the forbidden area, take it down!" Su Wanyue stroked her belly, feeling the joy coming from the sword baby, and smiled. That smile was colder than Wanzai Xuanbing. "I crawled back from hell just to tell you..." "——It's time for my sword to drink blood." In this life, her sword bones have become mature.
