17Day 677:
I got bored early this morning and started mining again, even though I knew that the zombies were still around and it was still too dark to go aboveground.
I found that under the granite was a vein of diorite, and under that was a vein of andesite, and under that was a vein of coal…
… and under that was a large cavern filled with zombies.
Fortunately (?) an exploding giraffe-zombie took most of them out in attempt to kill me. The rest I dumped a large load of granite onto, and hopefully they’re buried forever.
(Doubtful. It was a very big chamber. And they are, theoretically, already dead. So they have time to dig out.)
Anyway not long after that I prioritized getting back to the surface because I was out of food, most of my tools had broken mining or killing zombies, and I was really tired.
Back home for a long nap and a good dinner, and now I’m going back to bed.
