Introduction to the Harem: is the last hall of the Dragon King Cave, and it is also the hall with the most stalactites in the Dragon King Cave. There are thousands of stalagmites, nearly a thousand stone pillars, and tens of thousands of stalactites. They are in various shapes and dazzle, just like the emperor. Like the three thousand beauties, they dressed themselves up to be extraordinarily charming, hence the name "harem".
