I'm not too sure about the specific content of Guo Degang's crosstalk, but the chapters about the snail spirit, the mountain sea demon, the sea Taotie, the nine-headed monster, and other elements may have come from the novel "Ji Gong Zhuan". There were many versions of the Biography of Ji Gong. The more famous version was the Travels of Ji Gong, written by the Ming Dynasty novelist Shi Naian. However, the specific crosstalk works might have been created by other authors or actors.
