A 21st century urban female white-collar worker signed up to participate in a donkey trip to Tibet because she was tired of the ordinary nine-to-five life. It was precisely because of this experience and the sporadic past life memories in her mind that she decided to return to the Silk Road. Just when she thought that the so-called past life was just a fantasy, when she was trapped in the desert, her soul traveled through her past life, a destined identity, a destined time and space, and a person who was destined to be destined or not, and began a sadomasochistic love destined to have no ending.
