An Engineering Student's Daily Life Building Infrastructure in Ancient Times

Su Yunwan, a 25-year-old chief engineer on a nationally designated key water conservancy project, unexpectedly transmigrates into the ancient era as the good-for-nothing illegitimate daughter of a marquis's household. Abandoned by her family, she is forced to take her younger sister's place in marriage to a border prince rumored to be "crippled and on the brink of death," in the hope that the wedding will bring him good fortune. Everyone is waiting to laugh at her for being widowed while her husband is still alive. But she discovers that her new husband's fief is plagued by severe flooding and poverty. Her instincts as a hydraulic engineer kick in, and she digs canals, builds dams, and constructs waterwheels... Focused entirely on infrastructure, she accidentally saves the prince who was supposed to "die of illness." With modern technology at her fingertips and ancient political intrigue at his command, the two go from wary partners in a marriage of convenience to a perfect couple who join hands to reshape the world.
