This kind of war between cultivators is not purely based on the actions of high-end combat power.
Unlike the struggles between families or factions, where if one side's high-end combat power encounters issues and is annihilated, it would lead to that side being completely overrun by the powerful masters of the other side.
But the current state of affairs is completely inapplicable.
Not to mention this is a battle for survival between two races, both sides possess countless unforeseen resources, and the high-end combat power is an extremely special situation.
Indeed, Ao Songtian could wipe out the alien camp today, even slaughter all these aliens.
But if he did this, the aliens could do the same!
What would the losses matter then?
It's meaningless!
In the current situation, high-end combat power can hardly act, only serving as a restraining force to some extent.
