A down-on-his-luck college student goes fishing by the stream and accidentally obtains the inheritance token of the Green Emperor. From then on, his life changes dramatically, filled with joy and prosperity. With his little yellow dog, he goes up the mountain to gather herbs, catches fish in the river, plants flowers, keeps bees, hunts in the wilderness, tames rare and exotic creatures, and helps the villagers become wealthy, creating a utopian mountain village.
