In this chapter, we learn that the demon lord is already at 9 , and that he will soon be able to step into the "heavenly star realm" . In other words, he's about to enter the "supernatural" realm, where he can do whatever he wants. We learn that this is because of the fact that the "two auras" inside his body are stronger than the "demon blood sacrifice" , which is why he and his brother have been able to break through to the supernatural realm for so long. We also learn that his brother's brother, the yellow-haired boy, is also able to communicate with him through the magic of the sky. This means that the two brothers can communicate with each other directly, which makes them even more powerful than before.
