In this chapter, we learn that the jade that was found in the sea is from the "feathered emperor's" secret realm, which is located in the "Holy Sea of Heavenly Feather" . This is the place where all of the gods live. The jade was excavated from this secret realm by the feathered emperor, who was a god of the four gods. We learn that this is where the "domains of confusion" come from. The idea is that if you're caught in this "domain" of confusion, you'll go insane and start attacking people around you. This will help you learn how to fight in the future.
