The floor in the hub chamber was polished, and decorated with a massive snake symbol. Other than the chamber we entered from, there were five other exits. One large door—not nearly as large as the entrance, but still rather grand—directly across, that was tightly sealed, and four other doors, the size of normal double-doors, spaced around the sides. There were also spirit tablets near each of the four doors.
Examining one of them, it soon became clear that it held a Heavenly Secret puzzle. At my urging, Chen Huan left to work on another tablet puzzle while I did the one closest to the entrance on the left.
