I asked him what he is doing, turns out he sacrifices a bull to giants so that they wont attack his lifestock and he paints it so that they know is a peace offering.
I followed him for a bout 5 minutes, and he actually went to a giants camp.
The farmer left the bull near a mystic lake and went to go let the giants know that.. well they have a peace offering.
The giants then crushed the farmer as he screamed "Mercy" ....
This game is a amazing. Don't mess with giants.
