So today has mostly been spent building a communal bulk storage room complete with 192 double chests worth of storage I figure there are some thing we want to keep for ourselves....mostly diamonds, the shinies, they're sooo pretty and lovely and...ahem! So it is full of things we should have a lot like stone, cobble, andesite, granite. I've also put things like sand, gravel, redstone coal etc as I've more than I'll ever need of them. I've also put in iron, gold and all the prismarine blocks as we effectively have an unlimited supply of these.
I also started the dig for a slime farm It's only a 36 x 36 from the surface all the way to bedrock and y5 soooo only a little digging required There are a few projects I have in mind which need slime blocks or sticky pistons. A single slime chunk farm should produce way more slime than we'll ever need on this server but where's the fun in that so diging out 4 slime chunks next to each other to turn in to one massive slime farm
