In this chapter, we learn more about the jiuli's magic spell, "zhuyou skill," and how it can be used to manipulate souls. First, we're told that humans are like "a vase, and soul is contained within this vase." In other words, they're like a vase with a soul inside it, but the soul inside is like a human body. The only difference between the two is that the human body has a soul, while the soul in the vase has a "hei tan" . So, if you're a human, you can have a soul and a body, but you can't have both at the same time. So if you want to be a "supreme witch star" , you've got to cooperate with the other guy. But if you don't cooperate, he says, he'll kill you. He's not a witch star, he tells us, but he's a "9th - level star." He'll win the guy over first, and then he can be a ninth-level star himself.
