Following the question from the old monk, Xuan Hao slowly went into detail talking about the enlightenment orb and different applications for the enlightenment orb, using the way that he had ended up using the enlightenment orb back in the sect as one such example. Ensuring that he went into enough detail about it that these two would be able to copy the formations that had been used to some extent and confirm the accuracy of what he was saying.
Of course, they would still be lacking the enlightenment orb, but they would still be able to confirm what he said was true by using something different as a substitute.
