Lin Zhixia, a PhD in Agricultural Medicine, unexpectedly travels through time and becomes the daughter of a convicted official sentenced to exile. Her entire family is banished to the barren saline-alkali wasteland of the East Sea, where not a blade of grass grows. The bitter, salty water is poisonous, and the moldy grain is barely edible. With everyone trapped in a desperate situation, only she possesses expertise in soil improvement and water purification technology, enabling her to grow miraculous crops against all odds. The county magistrate and imperial eunuch envoys successively covet her farming secrets. Holding the ultimate trump card that determines the fate of the land, she forms an alliance with Prince Xiao Yuan, the Ninth Prince, who is hiding within the military ranks. Using her agricultural knowledge, she overcomes one crisis after another and protects her family's survival with thousands of acres of fertile farmland, carving out a new path to life in the depths of exile.
