Whether the nine-story demon tower in the novel really existed in history could not be confirmed because there was insufficient historical evidence. Although there are fictional towers in some novels, these towers usually exist to create plots and characters rather than real buildings in history. In reality, many ancient buildings have been destroyed or poorly preserved, so it is difficult to determine whether they really exist. Many novels mentioned the height and structure of the nine-story demon tower, but this did not mean that such a building really existed in history. If he wanted to understand the historical authenticity of the nine-story demon tower, he needed more literature and historical information to study.
