1. Demons advocate cow killing

    We are advocating cow protection and encouraging people to drink more milk and eat palatable preparations made of milk, but the demons, just to protest such proposals, are claiming that they are advanced in scientific knowledge. They say that according to their scientific way, they have discovered that milk is dangerous and that the beef obtained by killing cows is very nutritious.
