It's the Apocalypse, Who's Still Taking the Civil Service Exam? Me!

[Friendship-focused + no romance + farming + infrastructure development + feel-good story] A meteor falls from the sky, creating a survival crisis. Scorching heat roasts people, extreme cold freezes their feet, supplies are scarce, and zombies and mutated beasts run rampant everywhere. The good news is that they have supernatural abilities. The bad news is that none of them are useful! A spatial ability? No one told me it could only store dirt! A construction ability? No one told me it was a shoddy construction project! A refresh ability? No one told me there was any use for refreshing programs! The three reunite and coordinate their useless abilities, only to suddenly discover that they have activated a golden finger. Provide soil, mold mud, and make whatever they want. Once molded, it turns into whatever they made. But even though they have resources galore, why is their combat strength still so useless?! With wolves ahead and tigers behind, they decide to surrender. They become state employees, consume energy cores at top speed, rapidly level up their supernatural abilities, and have someone protecting them at their side.
