Water conservancy engineer Su Wan transmigrates into the body of Lin Wantang, a prince's concubine. She offers a river-control plan to protect herself, only to discover that her taciturn “husband,” Sixth Prince Xiao Jingchen, is also a transmigrator. One of them has modern engineering knowledge, while the other understands systems and political intrigue. From mutual suspicion to entrusting their lives to each other, they carve out a path through a deadly chain of plots involving Yellow River floods, a succession struggle, and remnants of the previous dynasty. He defies all opposition to turn the slur of “a woman meddling in politics” into the honorific “Wise Side Consort.” She devises strategies at his side and brings her river-control plan nationwide, challenging a century-old interest group. When Xiao Jingchen's origins are revealed and imperial power changes hands, they finally forge an alliance to rule together as emperor and empress, ushering in an era of reform that opens the civil service examinations to women, improves farming tools, and establishes a maritime bureau. Their legend is finally brought to light by an archaeological discovery a thousand years later.
