A water-condensing ability user from the apocalypse is transported into the body of a guilty woman exiled to a barren desert. Her husband's family considers her a burden, and everyone in the fortress is waiting to laugh at her misfortune. But no one could have imagined that this woman, sentenced to a deadly wasteland, hides a trickle of living water in her palm. Pointing to the barren land that everyone in the fortress dares not touch, she declares that there is water beneath it. From a single ladle of life-saving water to a wasteland where green shoots begin to grow; from a basket of wild vegetables exchanged for salt and grain to a spring that holds the lifeline of the entire Liu Fortress. Step by step, she turns everyone who once mocked her into people kneeling and begging for her help.
