After Lin Yan is unfairly treated by the favored eldest branch of the family during the division of their household, he receives nothing but a dilapidated thatched hut and a broken vat. Unexpectedly, he discovers that the vat contains a miraculous spring that can dramatically improve the quality of crops. Starting with selling fruits, vegetables, and medicinal herbs, he goes on to build processing factories, launch e-commerce livestreams, and develop agricultural tourism, creating the local brand "Yanshan Fresh." Facing repeated sabotage from the eldest branch and suppression by outside investors, he overcomes every obstacle and turns the tables on his opponents. Ultimately, he leads the villagers across the county to prosperity, transforming barren mountains into a nationally renowned agricultural science and technology demonstration village and achieving an incredible comeback from adversity.
