Has anyone ever found a map or layout diagram of the Ancient Tomb compound? Judging from what we see in RETURN OF THE CONDOR HEROES, the compound was built underground on Mt. Chung Nam, and was fairly large. There seemed to be numerous levels and chambers inside the tomb compound, although on the surface, all one could see was the igloo-like dome entrance (maybe the Ancient Tomb compound was the first-ever biodome).
The compound has its curiosities. What kind of ventilation system did Central Divinity Wong Chung Yeung build into the compound? What did the compound's inhabitants do about temperature control. Was it extremely hot in there during the summer months? Extremely cold during the winter months?
