Becoming a Priestess on the Beastman Continent

[Two male leads, one-on-one, no children, both pure, Beast World, System, world-building, farming] Xu He is great in every way, except that he's too softhearted. And now his soft heart has landed him in a real mess. Not only has he taken on an incredibly difficult job, he's also been bound to a ridiculous childbirth System.
