When the Eighth Saint Master followed Su Yu's gaze, his heart thumped and he became nervous. He then said, "This jade box is called a demon box and it has unknown origins. We do know that it came from a meteor that fell down on the central prefecture."
He then took a breath before continuing, "When people discovered the meteor, they found five boxes in it, and when they detected that a Floating Life Door existed within it, four of them were sealed by the Jiuzhou Emperor, while the last one was handed to the current central prefecture's king so that he could examine it and investigate its origins. But, just after the king solved the demon box's secret, he summoned a true demon, which heavily injured the Jiuzhou Emperor."
