In this chapter, we learn that the teacher has transformed the human body into a botanized organism, and that the role of fertilizer is to "balance the various functions" of the body, so that it will not be "mutated due to mutation" . We learn that there are many different kinds of fertilizer to choose from, such as rainbow candy, caramel, vanilla, chocolate, strawberry, spicy pork bone soup, spicy beef, pickle, and so on. We also learn that this fertilizer can be applied to our skin to make us healthier.
