You spawn in a medium island close by an extreme mountains biome look so cool. But that’s not what we will show you. Insead go to extreme mountains biome we will dig straight down from the spawn (you are spawn in the top of the tree) and you will find many good things in the deep underground. Keep digging straight down until you drop into a cave. You will get some diamonds immediately, other diamonds you need digging around and destroy some blocks. Finally, find the lavafall that mean you very close by mineshaft entrance.
