In the 10th year of Jiading in the Southern Song Dynasty (AD 1217), the war between the Song and Jin Dynasties resumed. The Jin army went south to attack the Song Dynasty. The Mongolian tribes had risen in the north and gradually encroached on the Jin Dynasty. Undercurrents of factionalism in the Southern Song Dynasty were surging. Shi Miyuan's autocratic power was beginning to appear. Local tyrants and Jianghu forces were intertwined. Although Lin'an City was prosperous on the surface, it was actually hidden in crisis.
Historical anchor points: There are "anchor events" (such as the lives and deaths of key figures, battle results, documentary records, etc.) In the historical process. These anchor points determine the direction of history. In this world, some anchor points are dislocated due to unknown forces (tentatively called "distortion power"), causing historical details to deviate from the true trajectory (such as the survival of generals who should have died in battle, the disappearance of classics that should have been preserved), and the dislocation of anchor points will trigger a chain reaction, gradually distorting the surrounding history.
