Hardcore, but I'm stuck in ONE BIOME

Today I spawn in one biome. I have 10 days before i'm teleptorted to a random place with only what I can carry in my inventory! Inspiration: https://www.youtube.com/watch?v=ROsCnoWkjpA&list=PL45ZcA8Tb39Lo83BhpeVDZtB5zlkfFP6B&index=3 This is a Hardcore Minecraft challenge. I almost died in this Minecraft run. It's Minecraft, but i'm stuck in this circle. This is an awesome Minecraft challenge. I build the ultimate survival house in Minecraft hardcore. This is like Minecraft but I can't leave this cirlce, or Minecraft but the border expands! #minecraft #minecraftchallenge #survival #minecrafthardcormode
