"Why are you trying to push an outstanding universe back by millions of years like you claim?" Then he raised his voice despite the strain tearing through his body, "Isn't the purpose of Planet Spirits and power systems to increase the strength of the universe's inhabitants? Isn't everything moving toward that path?!"
