A Poor Scholar

Traveled through ancient times and became a down-and-out scholar? The family is surrounded by walls but there is a beautiful lady! It doesn't matter, I know how to farm, do business, and fight. Making money shouldn't be too easy. The government and the public are in turmoil, and the current situation is chaotic. Even in the countryside, I am still a hero. Guard the country and quell unrest. I am a poor scholar of the first grade.
