Later, reclining under a tree, Master Li asks Ox to tell the story of Li Ling-chi, about an emperor who wanted tangerines in winter and was so expert in manipulating c-hi that he was able to pull the tangerine trees from where they were growing in the south and cause them to grow in the north. Master Li then reads a story from a scroll containing the frame story of "Dream of the Red Chamber", concerning a legend of Nü Kua, a sentient Stone and an evil flower named Purple Pearl. The flawed stone gains an evil soul from the handling of the goddess. It wanders around heaven causing mischief, until the Jade Emperor brought it in contact with Purple Pearl. The stone brought water to nourish the flower, which exorcised the evil, causing the flower to fall in love with the stone. It vowed to do the same for the stone. Later the stone returned to earth. Lao Tzu briefly possessed it, but hurled it away, crying "Evil!", as did Chuang Tzu.
