This is BASIC.

You jus need to travel 3,100 blocks from wherever you start and you'll come to a big rocky area where you'll find gold on the surface.

Once you've got uyour gold, find iron and make an iron pickaxe, then a gold pickaxe, then a diamond pickaxe, and then finally a Bloodstone pickaxe!

Just a warning though - unless you have set the mode to "no enemies" the further you get away from the spawn point the monsters that will come after you!
