I wonder if Bai Zemin might have a power in the future with which he would be able to merge BX, WY, CH, BD,YL from our universe to the universe with spiritual power. this way there would be only one version of them and that one version would be very strong. like Bai Zemin absorbed the evolution crystal from his other self. and it is implied that Bai Zemin from alternate universe should eventually kill each other. maybe then Bai Zemin could find the way for all the BX from other universes to merge together like the elf queen did to BX
