Lu Peng, dubbed the "witch", was thrown into the barren valley with one hundred and twenty-seven prisoners. Dead dust swallows seeds, salt corrodes water, and resentful mist kills people. With the Lu family's bloodline of hundreds of grains and longevity, she nourished the soil, built canals, and built public warehouses from a grain of green bean sprouts. But as the grain fields gradually matured, Si Yutai wanted to take back the seeds and lives; frontier troops, refugees, and grain bosses successively suppressed the situation. What Lu Peng wants to protect is not just a valley, but also a way for everyone to save seeds and have enough food without giving in to hunger.
