Agricultural and water conservancy dual PhD Lin Xi unexpectedly transmigrates to Heling County in the 1928 northern severe drought. Facing thousands of miles of barren land and corpses scattered everywhere, she relies on her professional knowledge to lead villagers in finding water and digging wells, switching to drought-resistant crops, and building canals to divert water. Fighting wits and courage with grain-hoarding profiteers, she turns barren dry land into bountiful fertile fields. From being suspected as a disaster star to becoming the provincial agricultural consultant, she uses a single seed to change an era, and ultimately transmigrates back to modern times, bringing this spirit rooted in the earth into university classrooms. Knowledge crosses time, and only by landing can it take root.
