Jiu Tang Shu
From Wikinoah English
"There was a Persian citizen herding camels in the Mount Kufan Medina. One day, a lion-man (a king) appeared out of nowhere telling him:
"There are three caves on the west side of Mount Kufan Medina. A large amount of weapons is stored inside the caves and you can go and retrieve them there. There is also a black stone with texts carved on it. You will become the king if you read and do what the carved text on the black stone tells you!"
