At the foot of Qingcheng Mountain, Bai Snake Suzhen, who has been practicing for thousands of years, needs to find a ray of "snow soul" left in the world in her previous life in order to survive a disaster. She transformed into a woman in white and stepped into the world, but by the broken bridge in the West Lake, she met Xu Xuan, a scholar with clear features and an old umbrella in his hand.
Su Zhen originally just wanted to take things quietly and figure out the cause and effect, but she was gradually affected by the warm and sincere heart of this mortal. But Xu Xuan didn't know she was a demon, he just felt that this girl was like a fairy in the snow, as if she had seen him before.
At the same time, Fahai, the patrolling messenger from heaven, quietly arrived. He was ordered to maintain the boundary between humans and monsters, but in this increasingly profound fate, he noticed an unbroken ripple deep in his cold Taoist heart.
When the truth about "Xue Po" is revealed, the entanglement between the three people in their past lives also emerges. A test about choice and obsession unfolds quietly in the snowy sky of Qingcheng Mountain - is it to fulfill the way of heaven or to follow one's heart? This time, can they survive each other and themselves?
