The Great Wilderness has suffered years of droughts and floods, leaving ordinary people struggling to make a living. By a twist of fate, the poor scholar Su Yi meets Ling Yi, who is highly skilled in agricultural techniques. With their backs against the wall, he withstands public criticism and joins forces with Ling Yi to promote high-yield crop varieties and traditional farming methods, leading the villagers in reclaiming wasteland and cultivating fields. He rallies the people to build irrigation systems, establish schools, and open businesses, using his wisdom to calm local unrest. He promotes effective agricultural practices to benefit people far and wide. Dedicated to improving livelihoods, Su Yi ensures that the people of the region have enough food and clothing. Once peace is restored, he chooses to return to a quiet life in the countryside, working alongside others to transform the once-barren wilderness into the granary of the world, fulfilling his lifelong ideal of passing down a family tradition of farming and scholarship while securing people's livelihoods.
