Iron Farm 30000/h

100 modules of 1 zombie and 3 villagers each, 300 villagers in total and 100 zombies

*ZOMBIES MUST HAVE A NAME SO THEY DON'T DISAPPEAR *IF IT DOES NOT APPEAR IN THE SCHEMATIC, EACH MODULE HAS 1 VILLAGER PER BED AND A ZOMBIE IN THE WATER WITH SOUL SAND *It is more efficient if you load the overworld and nether chunks at the same time *THE COORDINATES FOR THE NETHER MUST BE THE CORNERS OF THE LAST MODULES OF THE OVERWORLD DIVIDED BY 6

Tested only in 1.21.11 but should work from 1.17 onwards
