Shen Xixi, a quick-witted modern girl, transmigrates into the past and becomes an adorable little farm girl. By chance, she also brings along a phone that can connect to the internet.
The Shen family is poor, and the clansfolk look down on them, but Xixi uses her phone to turn things around: she avoids disasters with weather forecasts, makes novel delicacies with recipes, improves crops with planting guides, helps her family escape poverty, and makes a name for herself in the county.
After her achievements earn her a recommendation to the capital, Xixi draws on historical knowledge from her phone to help her father resolve political crises and help the emperor tackle problems affecting people's livelihoods. The Shen family becomes a pillar of the agricultural world. Her younger brother makes a name for himself in the imperial examinations, her sisters expand the family business, and the family flourishes.
The capital's powerful families grow jealous and covet what the Shens have, launching one attack after another, but under Xixi's leadership, the family repeatedly escapes danger. She also meets the gentle Gu Yun, and together they help the family prosper.
From a farming village to the imperial court, from utter poverty to a thriving family business, Shen Xixi uses her phone to write a passionate and heartwarming legend set in ancient times, inspiring people to yearn for a better life. Her story becomes one passed down through generations.
