Su Qing, a science student, and his family of five, together with their RV, travel to the end of the war-torn ancient dynasty. Faced with hungry people everywhere and ferocious officers and soldiers, my father, who had been a soldier, picked up an engineering shovel and organized the refugees; my mother, a chef, opened a kitchen with modern seasonings; my brother, who studied mechanics, modified farm tools; and my sister, a nurse, was responsible for logistics and medical care. Su Qing, on the other hand, used her chemistry knowledge to create cement and gunpowder... A year later, when the imperial army was defeated by their new weapons, the emperor was horrified to discover that this uprising team named "Su Family Army" had already arrived at the city.
