In this chapter, we learn that the two of them are in the middle of a battle, and that the battle is being fought on the ninth level, which is the highest level of the Celestial Empire. In order to stop the battle, the two are going to have to lose their cultivations, which means they're about to die. The only thing that can stop them is for the other to stop fighting, because if they don't, they'll be dead by the time the battle ends
