In this chapter, we learn that the siblings have been studying under the same mountain man, and that they have had enough of each other. They decide to tell each other what's up. They're not going to call each other "dog spirits" or "devil spirits" , but they do want to know what the heck is going on. One of the brothers tells the other that many monsters and "curiously spirits" have begun to show up in human society, and they've been hiding for a day or so. The other brother tells the younger brother that he's read the books the master collected, and the dead who die with "powerful obsessions" will transform into "liquor spirits" and affect the human emotions and bodies. In other words, they used to be in an eternal war with demons, but one day, all of their powers were finally restrained, and humans entered a "war of weapons" . The younger brother asks the older brother what he needs to do, and he tells him to tell him the truth about all spirits being liberated. The older brother says that the only thing he needs is a "rabies vaccine" to prevent the "liberation of spirits" in the future.
