I'm looking for the name of the fanfic!

Two weeks ago, I started reading a fanfic in which people exchanged meat for cattle (Venlil), but these venlils were crazy? They were happy to some extent to be eaten and be cattle. So I forgot the name of that fanfic! Please write if you know the name of that fanfic! (I'm sorry if you didn't understand what I wrote, English is not my native language.)
