After getting more established with my little farm and completely securing my food needs, I began to explore a cave system. It’s easily the most mammoth one I’ve ever seen.
Next step was to dig my way through to the top of the earth and create a more direct route into this underground chasm. If I want, I can start strip mining from here.
When I started exploring, this was the first cave that had a little “Central hub” from which many other tunnels seemed to branch off. I closed off a few and the rest got labeled.
The plan is to dig deeper from this point, since I understand that you get better items (like, diamonds) the deeper you go without hitting bedrock.
