In this chapter, the ji guardian explains that the root of his grandfather's disease is the cactus. He explains that everything the cactus does, including making his grandfather sick and tempting him to fall into love with him, is to get the magic ring. This explains why he seems to know nothing, but he always manages to make him blush. He also explains why the vine spirit did not chase after her when she escaped. He calls for an ambulance. He wants to find the four demons that have gone into hiding. To find them, he must return to the time of the Ming dynasty.
