Big Hole

The base of the Beloppten (ALS_TV, LK_Legends, .BlissfulPanda11 and Xhonig_BienchenX) looks pretty inconspicuous from the outside, but inside it's a huge hole. Inside, for example, is an automatic crate storage facility, a trading hall, a sugar cane farm, and a super smelter. The trading hall and the farms can be used by everyone.
