The chapter opens with a description of the "land of tranquility" , which is described as a "swamp between mountains" . It is a wine cellar built on a rock wall, and there are hundreds of houses and livestock farming at the bottom. The narrator explains that the prisoners in the "dragon-besieged magic circle" are prisoners in a swamp between mountains, and that the man who captured them was able to get the information from him just because he was careless. He tells the man to let them know that the "sorcery circle" is actually not such a bad thing. The man who saved the narrator is sitting on a plank road, waiting for him. He explains that his mother was killed by a dragon weapon, and he cannot remember what happened that night. He asks the man if it is the murderer who killed his mother, and the man replies that it is not him, but the calendar of da-zhou, the year 766, late spring, gao-jing capital, the outer hall of the yu-yang palace.
