In this chapter, Renji explains that the skin and bones of the monster are immune to the effects of firearms. Renji tells the audience that the development of military technology has to shift its focus away from combat to an "auxiliary" role. He tells Renji that he has analysed the battle recording of his battle earlier and that many times he could have a better strategy. He also says that the number of survivors in the area is not as great as he had thought. He says that he remembers that there were millions of people left in the county. He adds that he thinks ghouls will be even harder to deal with in the future since they are intelligent and will often pick up their battle skills in a secret. He suggests that using space-leap technology, they can eject the monsters into the sea even if they are defeated by the sea monsters. They can also get rid of sea monsters too, since the sea creatures are becoming more terrifying.
