Update: I noticed that the previous version is quite costly in terms of redstone, so I decided to modify it to make it more affordable in that aspect.

Auto trading hall with farm and zombification system included. Any corrections to the farm or simplifications are welcome.

Warning: the farm depends on how you orient it, it can break the villager distribution.
