Ye Zhihe, a modern agricultural graduate student, unexpectedly travels through time and becomes the legitimate daughter of a military family, framed by her fiancé and half-sister for treason and exiled to the bitterly cold Northern Wilderness. Facing desperate circumstances, she uses her expertise in dryland breeding and soil improvement to purify water, produce salt, reclaim wasteland, grow crops, and build water-powered mills. She transforms barren land into the largest granary in the northern frontier. Joining forces with Pei Xingzhou, the heir of the Marquis of Jingbei, who narrowly escaped death, she exposes traitors and settles old grievances. Together, they turn her from an exiled criminal's daughter into a female official overseeing agriculture, carving out an entirely new world in the Northern Wilderness.
