Su Qingxue was once the most useless abandoned disciple in Yaowang Valley, with mixed spiritual roots and poor cultivation. She was ridiculed as a loser by her peers and regarded as an ant by the world. The most desperate day was when the master who took her back to the mountain gate—the aloof, cold-as-snow-like ruthless sword master—kicked her out with his own hands. The reason is: The mind is not right and there are signs of being possessed by the devil. A hundred years later, when the only "Poison Immortal" in the world of cultivation was born, everyone knew what real fear was. She was dressed in green and had the most beautiful poison in the world around her fingertips. While talking and laughing, she could make the Dantian of a city's monks shatter and their cultivation level turn back. The upright genius who used to bully her and humiliate her is now prostrating at her feet, begging her with tears streaming down her face. Su Qingxue just smiled and said, "Is my intention evil? Now I am showing you that I am not honest." She thought that her heart had long been dead, until that day, in the wind and snow, the Qing Leng Sword Lord, who had not been seen for a hundred years, was looking embarrassed and kneeling in front of her cave with red eyes. What he asked for was not his own life, but an antidote. For the white moonlight on the tip of his heart, he could cure the poison called "Tongxin". "Qingxue," his voice was hoarse, just like that snowy night a hundred years ago, "As long as you are willing to save her, you can have my life, my cultivation... Whatever you want." Su Qingxue stroked the sleeping Gu snake on her wrist and smiled. "Master, it's too late. I am the inductor and you are the medicine for this antidote. To save your sweetheart, you need to... Be willing to become a demon for me." Kill Bai Yueguang first and then kill my ex. I will become an immortal by my own cultivation. The scene of a large-scale wife-chasing crematorium.
