It was a science fiction novel about the tragic experience of Song Huizong and Song Qinzong after they were captured by the Jin Dynasty.
Your question is a little vague. If you are referring to a science fiction novel that has a video function and the tragic experience of Song Huizong and Song Qinzong being captured to Jin, then I can provide some relevant information: Such novels usually involved time-travel, aliens, technology changing history, and other elements. In such novels, there was usually a device similar to a " recording function " that could record historical events, character scenes, and so on. The protagonist of the story might be a scientist or adventurer who somehow obtained this device and used it to record historical events. Then he or she might keep this record or spread it in some way to let more people know the truth of history. However, such a novel could also have some problems. For example, if historical records were tampered with or forged, the authenticity of these records might be questioned. In addition, if historical records were used for political or commercial purposes, they might also raise some moral and ethical issues. I hope this information will help you better understand the content of this type of novel.
