The narrator tells us that the knight's life ended just like this. He was just one person among 242,769 who died during the earthquake in tangshan. But his cause lives on forever, because countless people came to his aid at the time of the disaster. The narrator's grandfather found his purpose in life, and he and his grandson have to meet up with him, even though outsiders often laugh at them. It's nice to know that the narrator can go to his grandfather's side sooner than he expected. He asks if he can join the school. The school's purpose is to "kill the undead" and "go deep into the world" , and the narrator says that he is more suited for the school than he is for the seekers. He says that his only friend is his sister, who is the only one that he can lean on in his time of need. He tells the narrator that he still believes in his luck, and that when he's successful in his studies, he must enter the holy group and get a high position. He'll make his parents, who only contact him once a year, regret it. He wonders if something is wrong with the car, and penglai tells him that it's still a while away from turning into the undead. He explains that the law of "cause and effect" applies only to those who die before their corpse's blood is exposed to the blood of the corpse sage. If the sage dies before his blood comes from the corpse, the law says, then the sage's death is the cause of the death of the knight.
