More than ten thousand years ago an alien race landed on the planet Haixing, some among them fused their cells with plants and animals, forming the Yashou tribe. Some stayed deep under the ground and were called the Dixing people. Their cells mutated as well and they became capable of some supernatural powers. There was however peace between the three tribes. Until a meteor hit Haixing and the Dixing's resources started to deplete and they escaped to the surface and started a war with the Haixing and the Yashou people. The Haixing in the end won the war after they created 4 Holy Tools out of the meteor. The three tribes then agreed on a peace.
