Modern hydraulic engineer Gu Wanqing travels through time to a fictional ancient world where water control dictates hierarchy and status, finding herself reduced to a destitute refugee girl. With an entrusted jade pendant, she manages to enter the wealthiest Lu family as an adopted daughter. In the bridge-building competition, she optimizes traditional mortise-and-tenon techniques using modern mechanics, defeating her rival, the Wei family, and making her initial mark. During the flood season, she uses her expertise to forecast flood crests, saves an undercover prince, proposes the "Fish Mouth Water Division" conservancy strategy, and leads water control projects that resolve local droughts and floods. Exposing the Wei family's corruption that led to a bridge collapse, she oversees the construction of an open-spandrel stone arch bridge, eventually rising to become an indispensable first-rank naval commander who leaves her name in history.
