In this chapter, we learn that the magical substance in the can is spiritual energy, and that it can be harnessed to increase one's own spiritual power. In other words, spiritual energy is a kind of money-making substance. The magical substance can also be used to increase a person's physical power, so it's no big deal if you're a dude who's super-strong and super-rich. So, if you have the power, you can use it to increase your physical power. But if you don't, you'll lose the spiritual energy. And that's just the way it is. The dude who has the power is the one who can use spiritual energy to increase his physical power . And he's got the money to do it, so he can do whatever he wants with it. But the dude who doesn't have the money can still use the magic substance to harness spiritual energy for his own benefit. And if you want, he can also use it for the benefit of the other dude who can't use it. Yeah, sounds like a good plan.
