Xihuan Farming: Start by Digging Septic Tanks

What is it like to travel through the Middle Ages, become a knight lord, and step on shit as soon as you step out? In the evil Middle Ages, people pooped everywhere in the streets, bloodletting was used to treat illnesses, people didn't take baths to ward off evil spirits, and they ate black bread that could kill mice. And dragons, witches, elves? Then it's time to think carefully about how to farm. There is no way out, and people have to make a living on their own.
