When the apocalypse broke out, some people on Earth gained a System. Wang Chen chose the profession of creating skeletons. A standard skeleton soldier? No. Since he can make whatever he wants, why not build a tank first and have it crush everything in its path?
The zombies are utterly outmatched, falling one by one.
Then bones are pulled from their corpses, and all kinds of skeleton units rise to their feet.
This is completely backward from the zombies' perspective. Shouldn't humans fall and turn into zombies that rise again?
Just as Wang Chen uses advanced bones exchanged through the System to build a spaceship, invaders from a distant planet set course for Earth from outer space, armed with weapons designed to counter living creatures.
It seems they have no idea what they're getting into.
