In this chapter, Cai tells us that he will always live in the mountains. He feels that one day, he will be able to disappear, but to him, he is still a miracle. He says that letting go of others is the best way to protect them. Cai says that he still worries about others, because he still has the heart to do so. He thinks that if there are dangers, Cai will be the first one to run away, and that he is the real idiot.
