Minecraft with No Surface Challenge

Beat Minecraft with no Surface? Can you do it? You sure can by finding diamonds, finding ender men, going to nether (nether is infinite), getting 12 ender of eye and travel to the end to kill the dragon. Once you have killed the dragon the challenge has been completed. If you have completed this Challenge comment down below!

There is only 1 Tree in the World where you spawn, The world is 64x64x64 blocks in size and it is all stone with caves (No Surface), the world edges are surrounded by bedrock so you cant go to the surface as there isn't one.

Good luck!
