The Phoenix's Secret Treasure

Legend has it that in ancient times, there was a great demon named King Ailin, the foremost of the phoenixes. She subdued the myriad demons and became their queen. Before her death, she left behind these words: The blood of a phoenix descendant is the key to the phoenix's hidden treasure. Whoever obtains it can not only become the next Queen of All Demons, but also have any wish granted! And so the demons began searching for the phoenix's hidden treasure, and for its descendants!
