Yan Yingzhou accidentally obtained a system called the 'History Live Room', which allowed him to randomly invite the founding emperors of China to watch a documentary about the humiliation and struggle of China in modern times. How would they feel when the talented Qin Shihuang, the wise Emperor Gaozu of the Han Dynasty, the confident Emperor Taizong of the Tang Dynasty, the overconfident Emperor Taizu of the Song Dynasty, the suspicious and ruthless Emperor Taizu of the Ming Dynasty... These monarchs who had created a glorious era saw their proud country reduced to the point of being slaughtered by others, how would they feel? Is it anger, sadness, or will you see the unyielding backbone of this nation from the humiliation?
