Last time, that goddess had to tap into the divine power strength to kill Zhou Tian, which caused her to use that power excessively, and ultimately she was forced to be kicked out of this world prematurely. Now, even though they had made full preparations and the time that same goddess could stay in this world was extended by a lot, if she kept consuming energy in the current manner of fighting, that goddess would not know how much longer she could remain in this world.
If she could secure victory, that goddess wouldn't mind fighting Zhou Tian at all. After all, being kicked out of this world doesn't really mean anything to her, since she is not native to Zhou Tian's world, and being expelled simply means returning to her original world. As long as she could eliminate the threat of Zhou Tian according to their plan, her purpose for descending would be achieved.
