The scenery in danger adds strength to visitors, and they feel that they are not heroes if they don't go to the real pool. There is still a moving legend about the Black Dragon Pool: in ancient times, there were two dragons. When they grew up and separated, the honest Black Dragon took the initiative to give the White Dragon Pool to his younger brother, the White Dragon, and came to Gulou Valley alone. At that time, there was not a drop of water or a blade of grass here. The Black Dragon became a young man and worked hard day and night. The Yunmeng ancestor of Daxi Mountain saw that the Black Dragon was honest and hardworking, so he gave him a ribbon and 18 pearls. The Black Dragon sprinkled the pearls in Gulou Valley, thus forming the current 18 strange pools.
