Interdimensional Iron Farm

This is The Interdimensional Iron Farm. In this farm we use End Portals to reroute all Iron Golems and their drops to the Overworld. This means the farm itself can be stacked upwards or downwards, side by side, or, placed in multiple areas in The End, not near each other, because all of the portals output to the same place in the Overworld. This is controlled with the /setworldspawn command. Because this is a passive mob farm, the player is not required to afk at the location or anywhere else. To keep the chunks in The End loaded, we use the /forceload command. I could have made the farm much much bigger but I didn't want to make the file size too big. Big or small, all Iron Golems exit the portal to the same location in the Overworld. Exactly. On top of this, unlike many Iron Farms, we're using bubble columns under the zombies to make them bounce, to constantly break their line of sight with villagers so they can get that split second of rest they need to spawn a golem. All you have to do is stand at the kill chamber and watch golems fall from nowhere into the lava pit, or do something else while your chests fill up. And they fill up very fast. If the player uses the portal in The End, they will see the credits and arrive at the location set by the /spawnpoint command, or where they slept last. If you don't wish to watch the credits (75+ minutes), press Esc.
