In 1126 AD, on the eve of the Jingkang Revolution, the Song Dynasty was experiencing internal and external troubles, powerful officials were in power, and people's livelihood was in decline. Modern engineer Li Jing accidentally traveled through time and became the lowest steward of "Anjifang", a refugee camp outside Bianjing City, an imperial estate on the verge of collapse. What he faced was not only the iron hooves of the Jin soldiers who were about to move south, but also the layers of exploitation by internal officials and the despair of the refugees.
