Bai Qiange, the last nine-tailed fox in the world of immortality, is an old monster who has lived for three hundred years. In order to avoid being chased by her enemies, she hid her nine tails, changed her name to "Chaolu" and hid in the most popular gold-selling cave in the world - Chunfengdu, and became an oiran who turned all living beings upside down. She is here to laugh and collect intelligence, like a spider dormant in the shadows, quietly weaving a web of revenge. She thought she was dead in her heart, until that snowy day, she picked up a dying man covered in blood in a back alley. After the man woke up, he forgot who he was and his all-round cultivation. He was like a piece of clean white paper, with only her reflection reflected in his clear eyes. He would awkwardly tie up her hair, leave a light on when she came home late from a social gathering, and subconsciously stand in front of her when other guests tried to make a move, revealing an awe-inspiring sword intent that even he himself was unaware of. Bai Qiange moved a heart that had not been moved in three hundred years, and she was greedy for this stolen warmth. She even began to pray that he would never remember the past. However, God did not have his wish. When he was on the cliff, in front of both good and evil people, and in the light of swords in the sky, he regained his memory. He became the aloof and ruthless swordsman who killed her entire Qingqiu clan three hundred years ago with one sword. His hand holding the sword was shaking, and he asked her with scarlet eyes: "Bai Qiange, it's been so hard for you to hide this from me for the past three hundred years." But she smiled, so sadly: "Yes, I'm so hard. It's so hard that... I can't sleep without hugging the enemy who exterminated my clan every night."
