It is an ancient farming novel that combines pastoral healing with suspenseful foreshadowing. It is set in a remote mountain village of the Chu Dynasty and tells the story of Na Xiaoman, a time-traveling girl with modern agricultural knowledge, and Bao Yanzhi, a troubled general with a mysterious past, who work together to open up wasteland and rebuild their homes on barren land. One is a "farming wizard" who uses science to improve the soil, and the other is a "hidden swordsman" who hides his sword and wields a hoe. As they work together at sunrise and rest at sunset, they not only turn the wasteland into fertile soil, but also see a new version of themselves in each other's eyes. When the rice fields are heading and silkworms are spinning cocoons, the pursuit of the outside world and the undercurrent of the court are quietly approaching - can she use her wisdom to guard the land watered by her hard work? Can he find his true home between the countryside and the world? Let's see how the two protagonists compose a pastoral hymn about growth, redemption and bondage on the Longmu.
