This mod moves mite's underground dimension to 1.19.4 and adds lots of mobs,
but there are a lot of details that are not processed to complete.
I've made some changes from the original
(Nether doesn't need to be built in the underground, because it's not finished,
underground portal is not finished too, you must use flint and steel toright click on the portal's wall)
you mut buid the portal bedrock nearby.Use crying obsidian as the portal frame temporarily, because obsidian needs to modify the vanilla code
