In the 21st century, military doctor Bridget dies in battle—only to wake up in the body of a 12-year-old street urchin in ancient times, already trapped in a scheme for a ghost marriage. Rescued by Shattock, she learns from him that this is the Great Jin recorded in history, a dynasty doomed to chaos and suffering. Determined to change fate, she volunteers to become Shattock’s child bride. Under this guise, she flees with the villagers of Tree Village to escape disaster, secretly searching for the lost prince rumored to be among them. Along the way, Bridget uses her medical skills and system knowledge to feed, heal, and protect the villagers, becoming their lucky star. She grows close to Shattock—and soon discovers he is the very prince she’s been seeking. Five years later, with the emperor gravely ill, Bridget is summoned to the capital to treat him, while Shattock, now the top scholar, enters government service. Together, they defy prophecy, eliminate traitors, prove their identities, and ascend the throne. From a ruined dynasty to a thriving realm, the little street urchin and the lost prince forge a legendary story of love and power.
