Some families start their own store or restaurant to make it big and then let the next generations take care of it, sometimes reaching a good success. Others don't have that much interest in commerce and prefer to do something else, trusting their luck and ability like this strange family business. Either choosing to be the son or the daughter of a couple of explorers, your daily job is to search abandoned fields for jewelry or any treasure, which can make you find from a dangerous land mine that can still explode to maybe a relic worth thousands or millions of dollars. It all depends on how lucky you are and if your machine really works, for it's based on its instructions that you will dig the ground and look for valuable items. Not every day is a good one, so don't give up just because you didn't find anything.
