In this chapter, we learn that the nine-headed pale owl has been refined into the supreme fairy-dan, which contains the blood of the great demon-divine tribe. This is a big step up from the pale owl's original form, but it's still not enough to transform the owl into a giant fairy. The only thing that's keeping the owl from becoming a giant beast is the fact that his aura is stronger than it was when he first saw the owl. This makes the owl look like a living sacrifice, which is why he's so upset. He wants to thank the owl for breaking the illusion, but he knows that if he loses, he'll never be able to recover his memories.
