The old farmer Zhao Laoliu rescues a fallen Azure Dragon. In return, seeing that his son Shitou is mentally impaired, the Azure Dragon promises to open the boy's wisdom over three years. The wealthy Qian Dafu covets divine fortune; feigning charity while plotting greedily, he pollutes the Dragon Pool to force the dragon into appearing, accidentally awakening a serpent demon at the bottom. Three years later, Shitou returns fully learned. Concocting the Spirit Cleansing Powder, he aids the Azure Dragon and uses his own essence blood to awaken the dragon scale and suppress the serpent demon. Qian Dafu squanders his entire fortune due to greed, while the virtuous Zhao father and son cherish benevolence and repay kindness, returning to the Dragon Pool year after year to thank the Azure Dragon.
