The System Made Me Emperor

A modern man named Lawrence finds himself transmigrated into the body of the magistrate of River County, a land gripped by famine. He wins over doubtful officials and soldiers with unexpected tools, from pig feed meant to show his resolve to congee served with pickles. As he outwits the schemes of Evan and helps turn the tide against the rebel leader Simon, his modern know-how starts to reshape the fortunes of the people around him.
