Oh, that reminds me of a project I once tried on a server I decided to stop going to.
Yeah, I tried to make my base the
entire underground.
I only got up to finishing Parsee's Bridge before things went south.
Yeah, surprised that I have minecraft? I just lost interest in it for the most part, up until your idea Artemis.
My preferred building material for most things is obsidian though, due in part to obsidian being a blast-resistant material. Creeper's can't blast what they can't damage!
But I generally prefer to just blow up things with TNT(which is another reason for my building preference), so I was generally the go-to guy for hollowing out caves and stuff.
So if you guys need a hand in hollowing out space for Chireiden, I might be helpful as long as I can get my hands on at least 10 TNT blocks and a good enough pick to hollow out a spot to place TNT.
Of course, if we're gonna build the palace of earth spirits, we may as well do the whole underground right? I think I'd be able to complete that old project with you guys though.
Last server I was on and tried it, I was the only guy building it, everyone else was too interested in building stuff aboveground. they didn't understand the joys of making subterranean buildings!
Though they did have a nice little Hakugyoukurou built.
If you guys want a Demolitionist/Digger to lend a hand, don't hesitate to ask.
I'm not just a researcher y'know.

If only there were actual drills in minecraft....
