When the Northern Song Dynasty fell in 1127, Zhao Gou wanted to flee south to Yangzhou after hastily ascending the throne, but encountered a mysterious incident in Mingdao Palace. After falling into the water and waking up, he was no longer the cowardly King Kang, but "Zhao Jiu" with memories of the future. Faced with the pressing advances of the Jin Army's cavalry, the surrender arguments from above and below the court, and the hopeless situation of the Hebei rebels being isolated and helpless, he quietly laid out plans in the Huaihe River Basin - deposed Huang Qianshan and Wang Boyan, the important ministers of the main peace faction, reused main battle generals such as Zongze and Yue Fei, and secretly contacted the Taihang Mountain Bazi Army, Liangshan Boshui Army and other civilian armed forces in an attempt to build an anti-golden defense line with the Huaihe River as a barrier.
The intention: to use the memory of nine hundred years to break the fate of Pian'an and rebuild the bones of China on the banks of the Huaihe River.
