An old and poor man is busting his ass to dig gold in different valleys. He has to raise his family,so he has to work hard. There are golds and diamonds scattered here and there in the valley. However,before he could reach those golds,troubles come first,he must overcome difficulties. The rule is that he must roll up enough golds in a limited time,if he can't reach the goal of that level,he'll be ousted from there and stay hungry for a whole day.
