I Just Want to Plant a Field, Disasters Are Chasing My Family

[No space + no system + farming + escape] A family of four accidentally traveled through ancient times and just wanted to live a peaceful life farming. They didn't expect one famine to follow another. It's difficult to feed a large family, but you also have to help the whole village get rich together, help the fellow villagers who came here to stabilize their officialdom, and help the rebellious prince save his life? Even if they don't want to be the richest man, the emperor is still chasing after them to fill the national treasury. Time is tight and tasks are heavy, so what if there are no plug-ins? We are our own plug-ins!
