Lin Xi woke up in a desperate situation and became the only young man in the refugee team, surrounded by only the old, weak, women and children. The road ahead is filled with starvation and death, and there are pursuers pressing behind. With modern wisdom and tenacity, she led everyone to escape into the desolate "Xiyuanwa" to open up wasteland and save themselves. From learning about yams to feed her family, to burning wasteland to fertilize fields, from building straw huts to building water conservancy projects, she used pragmatism and innovation to ignite hope. When the powerful oppressed her, she "worked for relief" to unite people's hearts; when the rich and powerful coveted her, she formed the "Women's Guard" to defend her homeland. The road is blue and the sand gathers to form a tower. In the end, the barren lowland turned into a paradise of troubled times, with waves of wheat surging and houses in ruins. Linxi stands on the land cultivated by one's own hands, witnessing the power of the people's aspirations - no need to rely on others, taking root downwards and growing upwards, with full grain warehouses and people working together is the most stable country.
