You might have seen empty minecraft worlds before, but the largest I've seen is 2,000x2,000, and then it generates regular minecraft terrain. Worlds that do go on forever (up until now) used mods. No matter how far away you go, this one will just generate empty air in vanilla minecraft. I myself am working on several map ideas and creative builds and i thought other people might be able to use this too.

I've added three chests with the items you see above. These are things that you cannot get without cheats or hacks.Such as:
Level 10 enchanted armor/tool
Level 10 speed and jump potions (they will look like 9 but they are 10)
Portal blocks
Spawners
Lava and Water Blocks

The bedrock block you see is the player spawn.
If you would like to see me add more hard to get blocks, please post them in the comments.
