Doomsday Farming System

Whenever people talk about Fang Cen, they all say the same thing: "He never does anything useful. If he hadn't been born into a good family, who knows where he'd be now, grazing on grass." But Fang Cen is pretty happy with things as they are. His capable older brother takes care of the family business, so he can live very comfortably on his share of the profits and the pocket money his parents and grandparents give him. Then one day, a planting System with poor eyesight found him. Fang Cen suddenly realized that he was supposed to be the protagonist, destined to take down villains with one hand and deliver face-slaps with the other. Fang Cen says his family gets along just fine, so there's no need for face-slapping or taking down villains. He just wants to get rich, marry a beautiful, wealthy woman, and reach the pinnacle of life. Just as he was getting ready to make a big move, the apocalypse arrived.
