Baize, an ancient mythical beast, is all white, can speak human language, and understands the emotions of all things. He rarely comes out, unless there is a saint who governs the world at that time, and he comes here with a letter. It is an auspicious beast that can turn misfortune into good fortune. The girl Cuicui and the last Bai Ze in the world met under the banyan tree and got to know each other. However, Bai Ze's indifference and human selfish desires are all just a trap in the end.
