The Opposer knew exactly how Heaven and the world worked. He even knew better how the Heavens worked than the Heavens themselves, except for the highest one. The Opposer also knew how this whole situation would go down.
This lower Heaven had no clue what was currently happening in its world. The Heaven of this lower world only had strength and knowledge similar to people in the Unity Realm. The concept of a physical embodiment of the concept of lightning couldn't be understood by it.
The most probable way this would go would be that this lower Heaven was destroyed before it could even alert its parent-Heaven. At that point, this thing would ascend into the parent-middle world and then absorb that one before this Heaven could do anything. The same thing would happen until this thing reached the highest world.
