Lu Yuan, a doctor of modern agriculture, accidentally traveled to a deserted village in the late Eastern Han Dynasty. Troubled times were approaching and the people were displaced, but he awakened to the "Shen Nong Vientiane System", which could summon high-yielding crops, improve farm tools, and even deduce the layout of farmland.
