Yeluhong, a Khitan nobleman, returned to the Song Dynasty, but became a lamb to be slaughtered; the Xixia legacy was famous and heroic, but he died and was reborn, and became a refugee in the Song Dynasty. Two alien souls, one human and one sheep, were accidentally bound to the twin systems of "Muxin" and "Beast Behavior", and met on a narrow road in the turmoil of the Qingli years.
One uses the "Muxin" system to gain insight into people's hearts, and works step by step in the streets and countryside, trying to find a chance for himself and the people behind him in the chess game of the Song Dynasty; the other uses the "Beast Behavior" system to evolve and transform, from meat on the chopping block to the master of the pasture, using the body of an animal to see through the treacherousness of the human world, and repeatedly reversing the deadlock.
When Xixia's cavalry approaches the border, when Khitan's spies lurk in Bianliang, one person and one sheep, from mutual vigilance to life and death support, their hoofprints and footprints will eventually leave a path that subverts the fate of the Song Dynasty - will they be reduced to the dust of the times, or will they leverage the pattern of the three dynasties with their little power?
