The worldview of this novel is based on the middle period of the Kaiyuan period of China's prosperous Tang Dynasty (around 725 AD). The core innovation is that the ancient Zhou Dynasty was not a simple slave dynasty, but a secret civilization that mastered "astrological calendar + cultural inheritance". Its core inheritance was sealed in the "Zhou Ding" and was guarded by "Ding Guardians" passed down from generation to generation. They did not interfere with the secular dynasty, but would secretly intervene when there was a "cultural fault" in the dynasty.
