Zhao Changhe was baffled. He flipped through the "Mountain and River Atlas" left by the Ancient Xuanwu to examine records about this region, but to his disappointment, the Xuanwu obviously wouldn't have noted the burial mounds of the Spirit Clan. He found nothing of use.
Comparing it to other records, he found no difference in tone regarding the Spirit Clan, nor any content that suggested a connection between the Spirit Clan and Emperor Ye's system.
So what was the significance of Vermilion Bird and Xuanwu converging in the wild southwest?
A celestial event?
