Before the battle, jiangting tells the warriors that he's coming to kill them. He tells them that they're all innocent people, and that the sky dragon and the demon dragon are killing each other. . They're also their enemies, he tells them. They can't just blame each other, he says. The sky dragon fell, and then the dragon fell and killed the world. The demon dragon wanted to see that dragons were killing one another, and he wanted to restrain them all. The only way to stop this is to use the purifying power of your bloodline to save the martial cultivators.
