This is my farm world I've been working on. It includes:

Iron Golem farm

Enderman farm

Slime farm

Mob farm

Guardian farm (I forgot to get photos of it)

Blaze farm (also need to get photos for)

Gold farm

Melon and Pumpkin farm

Cactus farm

Sugar cane farm

Carrot, Wheat, and Potato farm

The location of my guardian farm is: X= -703.649  Z= -3024.076. It is easier to go through the nether to get to the guardian farm, I have added signs. There is a little hut next to my house named the diamond shack. There is a chest in the center of the shack filled with diamonds, but it is a trap so I wouldn't open it. I built it because while I had opened my world to LAN so a friend could help me with a build, someone else I didn't know joined and wreaked havoc on my world. Hope you enjoy this world if you download it.
