Benefits, everything was for benefits! The orcs had started this war for their own interests, and the Church of Light had also schemed against the orcs for their own interests. The Roson Empire had also done so for their own interests.
It would be stupid to talk about feelings with these big forces. Even the honest orcs did it for benefits. If they couldn't get benefits, who would be willing to fight? the reason why orcs liked to fight was that they could get benefits from the war, while humans didn't like to fight because they couldn't get benefits from the war. It was that simple.
The negotiations went very smoothly. This was the result that the beast King wanted. They wanted food, cheap food, so that they could gain more benefits for the beast clan.
