Alien Beasts Invaded, and the Country Asked Me to Fight

[Alien beasts + super powers + alien races + different worlds + universe exploration + unknown] The world mutates, strange wormholes appear, and alien beasts come out, killing all the creatures in the world. The invasion of powerful alien races has caused the world to fall and move towards a dark age. The human race rose up to fight, but was retreating steadily. All parts of the world were occupied by alien beasts and alien races. At this time, Qin Xiu stood up. "Those who invade the world will be killed without mercy, and those who kill our human race will be killed without mercy." PS: Creation is not easy. I hope everyone will support me.
