The soul of a modern agricultural doctoral student travels to a dying boy from a poor ancient family, and is bound to a "serious farming system" with the ultimate goal of "solving world hunger." The system rewards are all "serious" things such as high-yielding crop seeds, advanced farm tool drawings, and basic agricultural technologies.
Lin Mo (after his name after traveling) started from a desperate situation. He used modern knowledge and serious systems to plant high-yield grains, improve agricultural tools, build water conservancy, and develop villages from one acre of thin farmland, gradually accumulating strength and reputation. In the process, he not only has to fight against natural disasters, overcome land annexation, and deal with the exploitation caused by collusion between government and businessmen, but also change the deep-rooted ideas of small farmers and the inertia of the bureaucratic system. The ultimate goal is to achieve "no hunger in the world" and in the process gradually uncover the secrets behind the system and the reasons for his own time travel.
