Lin Wang of Yellow Earth Slope Village is the first college student to come out of the village. Back then, the whole village pooled money and effort together to support him in finishing college. But he went far away to the city to study, and for a full ten years there was no news of him, gradually being regarded by the fellow villagers as an ungrateful ingrate. Just as everyone was slowly forgetting him, Lin Wang suddenly returned to his old homeland. The reason was that his mother fell seriously ill, and he was coerced to return home by the capitalist Zhou Mingyuan grasping his weakness. Externally acting as the pawn of capital, his conscience within not yet extinguished, he secretly collected black materials. Having gone through hardships, with the help of Su Man, the technical backbone of the Agricultural and Rural Bureau, he defeated the capital layout and led the whole village in planting traditional Chinese medicine herbs to become wealthy!
