In the 1960s, Wangshantun in the north suffered a severe drought with scarce water sources, posing huge challenges to production and daily life. The protagonist Li Xiangnan rooted himself in the countryside, harboring a sense of responsibility toward the land and villagers, and was not beaten down by natural disasters and conflicts. Relying on experience and persistence, he explored underground subterranean rivers, organized the masses to dig wells and build canals, and actively sought ways to break the drought predicament. Along the way, he adhered to his bottom line and handled matters fairly. Facing the conflict over water grabbing among various villages, he proposed a fair distribution and water ticket sales plan, taking into account the survival needs of people in every commune; when construction sites encountered material shortages, tunnel collapses, and other dangers, he rushed to the front and stepped forward in moments of crisis.
