During the Shaoxing period of the Southern Song Dynasty, the Central Plains land sank, and the Jin people trampled thousands of miles of rivers and mountains with their iron hoofs. From the Xin family in Sifengzha Village, Jinan, the grandfather endured humiliation and served money, and the father adhered to his integrity, raising two young men with high aspirations. The eldest brother, Xin Dao, is a talented man who is familiar with classics and history, knows the art of war, and has the ambition to regain the Central Plains; the younger brother, Xin Yi, was born in sorrow and accompanied his elder brother, witnessing the suffering of the people and the arrogance of foreign races.
