Resurrection: Necromancers and Steampunk

I am an ordinary programmer, but I didn't expect that the zombie apocalypse would happen as soon as I resigned and went home with my bucket. As expected, I still died. I didn't expect that I would be reborn seven days ago and get two systems. In the apocalypse, I have the necromancer system, with countless skeletons at my disposal. In the apocalypse, I have a steampunk system, with political power emerging from the barrel of a gun. Let's see how I eliminate all evil and build my own pastoral oasis in this apocalyptic wasteland!
