Xue Ren was shocked to see someone with the ruler's destiny here.
His body went all demon for a second, before utilizing the divine fire coat of his! He had his demon powers being all here, but compared to the trained fire and ice, it was all pitiful. Xue Ren was mostly waiting for Rushai's throne to give him what was his, and with the recent finding about his children, Xue Ren was already set on going to the hell's world.
So he just needed a time to get his things done.
But now, he was a pitiful demon clad in fire divinities!
Nevertheless, it was fine. He needs his demon's ruler powers to completely beat this guy and absorb his flames! Thanks to it, all the divine bloodline will end up within his grasp! After all, Rushai himself awakened his Ruler's bloodline from the greedy's world's core.
It means, that the molten world also possess one that had given a birth to such ruler of fire.
