According to legend, the Emperor of Heaven had a library that contained the best and most beautiful things in the world. It was named the Kui Huan Pavilion. There is a fairy in the middle, sweeping and sweeping to purify it, and the years will be endless. The Emperor of Heaven's Royal Cavalry, Jiucang, has gone through thousands of calamities and cultivated into a human form. One day, I saw the fairy Lehuan, who was graceful, confused and graceful. I was very happy and promised each other. Thirty years later, the fairy and Jiucang went away together, and no one came in after that.
