Resist Invasion

While humans are still slowly developing technology, alien races are already deliberately preparing to launch war. God seems to have already determined everyone's destiny, and he, an ordinary urban white-collar worker, is destined to embark on the road of revitalizing mankind. Human beings need him to constantly transform and strengthen before they can defeat alien races. He leads the human army, and he dominates the universe. Who knows what the real purpose of these racial wars is? No reason! Just for the entertainment of the gods!
