In this chapter, we're introduced to the concept of "vital qi" , which is the energy that powers the universe. It's the same energy that's used to power the sun, the moon, and the stars. It also powers the "six paths of reincarnation," which are the paths that lead to heaven, hell, purgatory, and hell again. This is where the "ghost realm" comes into play, because the "ghouls" don't seem to care about the humans in this world. The "ghosts" aren't interested in the humans, and they're not going to take them away when they get old. The only thing that matters is that the humans are still alive, and that they'll be able to learn from the "runes" . The runes are a great way to learn about the world, and you can use them later on to learn more about the future.
