There were three prophecies in the Jade Box:
The first prophecy was that the Chessboard Island would welcome an Angel’s emissary. The person described was naturally the same as the priest.
The second prophecy was that there was a huge spirit stone mine buried under the Chessboard Island. If the spirit stone mine was not completely mined, the chessboard island would forever sink to the bottom of the sea.
The third prophecy was that one day, when the spirit stone mine was difficult to mine, the angel would walk out of the turtle shell and give them a helping hand.
Of course, if the priest knew that one day, there would really be a pervert coming out of the turtle shell, he would never make up the third prophecy.
The priest said that the three prophecies in the Jade Box were a warning from the sea god to the islanders. He kept on playing tricks, and then the islanders were fooled!
