Anti-PVP Base

In the first permanent server I went to, it was a PVP server so I wanted to take the precaution to be safe. I ran/walked 50,000 blocks from spawn [Direction will not be revealed]. There I found a mushroom biome, where I adopted to be my base. It is completely safe since it is underground and safe to high from invaders and it is too far for any person to try to find. The mooshroom that used to be there actually provided a permanent source of mushroom stew.

I made a video tour of this too!
