Reborn in 1979 in a small mountain village, Li Weiguo faces a desperately poor household: his eldest sister, who has endured countless hardships; his second brother, honest and hardworking; his fourth sister, with no way to continue her education; and his fifth sister, diligent and innocent. The villagers are struggling to make ends meet, longing for wealth, happiness, and change. With decades of experience from his rebirth and the unexpected ability to control water, Li Weiguo starts by taking over a reservoir. He farms to support his family and leads the villagers to prosperity through hard work. Swept along by the tide of the times, he finds fortune through water and thrives wherever water flows. The time will come to ride the wind and cleave the waves, setting sail across the vast sea.
