That is very impressive Simple but very effective is exactly what I love about parts of the game I may adopt that storage style into my new world when I get around to starting it.
I tend to over complicate things But I really like your storage setup so I will try to have some restraint
lol just get a pick with eff5 unbreak 3 , mending and start diggin out a huge hole lol
mine took me about 1-2 weeks because i do not play on daily baisis. It's worth it on one hand , on the other nope.
1. You have always problems with zombies spawning there , 2nd is that lucky for me unknowingly i dug into a slime chunk so even when i sleep in my bed there are slimes jumping all around the place.
2. The good thing is that its a big more of a challange to dig out so much space to put everything , the mob spawner i made outside the base is huge on 3 levels and that was a challange itself because i needed bones and gunpowder and it looks like it will be working for a loooong time.
You have to always keep an eye out for zombies as i said for they are a real threat to the underground villager breeder that i made.
I am now thinking of making an automatic wheat/carrot/potato farm with villagers underderground wich i never did do it before so wish me luck
