If you travel 3,100 blocks away from Spawn you will be in this big rocky area where you will be able to easily find gold on the surface. Use iron to make an iron pickaxe to get the gold and then make a gold pickaxe to get diamond. Make a diamond pickaxe using diamond to get Bloodstone and use Bloodstone to make a Bloodstone pickaxe which can then be used to get more of whatever you desire. If you are playing Survival mode and you don't want more monsters to spawn and come after you the further you progress in the game you must set the game mode to 'No-Enemies'.
