The World Tree stands in the sky, supporting nine continents, called Kyushu. Nine major races are distributed in Kyushu. Three thousand years ago, the human race Yu unified the Kyushu and established the Qin Empire. He used the power of the Kyushu to cast the Nine Cauldrons. Three hundred years ago, nine rainbow lights flew out of the palace of the Qin Empire. It turned out that the Nine Cauldrons were lost. Since then, the world has been in chaos. The Qin Empire has also been in the sunset. At this time, a legend has been spread that the one who wins the Nine Cauldrons will win the world.
