Jiang Man, an agricultural science student, is transmigrated into the body of a convict and sent to the frontier.
Liu Ying, who used to look out for her, gets first pick of a wealthy, gentle military household and advises Jiang Man to steer clear of Gu Yanshan, the cold-faced company commander with a bare-walled home who eats three heaping bowls at every meal.
But Jiang Man takes Gu Yanshan’s hand. “You keep me safe, and I’ll make sure you never go hungry.”
She has a “Harvest Almanac” that can assess soil fertility, warn of frost and pests, and record lost drought-resistant farming methods. But it can’t conjure a single grain out of thin air.
Liu Ying waits for her to starve. Instead, Jiang Man clears land, channels water, and builds a grain mill, turning a barren military farm into a granary.
Gu Yanshan rises from company commander to general, handing over his military pay and using every battlefield achievement to back his wife.
Then enemy forces surround the city, and the whole town has just three days of food left. In front of everyone, she opens an abandoned storehouse.
As the doors swing open, everyone’s faces change. What’s hidden inside isn’t grain at all!
