Jiang Wanning, a researcher at the Academy of Modern Agricultural Sciences, accidentally traveled through time while improving cold-resistant rice seeds and became a child bride in Qingshui Village of the Chu Dynasty. The barren mountain village, the mean mother-in-law, and the fate of being sold off were changed by a flash of blue light in the palm of her hand - she discovered that three-thirds of the thin field in the backyard was actually a spiritual field transformed from fragments of the ancient Shennong's "Yun Dream Mirror", which can have a mysterious resonance with the crops. Relying on her knowledge of modern agricultural science and her spiritual golden fingers, she spread hope in ancient farmland: improving cold-resistant rice seeds, cultivating off-season vegetables, and promoting new agricultural tools. She grew step by step from an oppressed orphan to a "field fairy" who attracted the attention of the government and the followers of the people. When Su Mingyuan, a mysterious man from modern times, breaks in with half a jade pendant, the two uncover the connection between the spiritual field and time travel, and compose a hymn of farming across time and space in the fragrance of rice and frost, allowing the barren land to bloom with the sprouts of civilization.
