He was the crown prince of Nanhai, and he picked her up in the barren mountains in winter. It was snowing heavily that day, and she curled up in his sleeve. There was a faint fragrance of white lotus in her warmth.
He took her with him to educate him, and she slowly grew up and became a little snake fairy who had practiced for five thousand years.
She calls him Xiaobai, and he calls her Qing'er.
She had intermittent memories of her past life. She thought the person in her dream was her "sweetheart" and persisted in searching for him, but he accompanied her in the search.
After gathering seven "exquisite mirrors" in the world and going through seven unparalleled love stories, she finally discovered that the person she had been looking for had never left. Even though her soul was gone and only her thoughts were left, she still returned to him; and he, even if he had been separated by a thousand lives, even if his appearance had changed and the past was no longer the same, he could still recognize her at a glance among thousands of people.
