What is the origin of Panwang Taoist?

Wang Daoren is a character in "Water Margin". He was born in the Northern Song Dynasty and was nicknamed Flying Centipede. He lived in Centipede Ridge Cemetery. Because he was good at yin and yang and could understand Feng Shui, he stayed at Taigong Zhang's house to observe Feng Shui. When he saw Taigong Zhang's daughter, he had evil intentions and refused to go. After living in Zhang Taigong's house for three or two months, he killed all Zhang Taigong's family, but forced Zhang Taigong's daughter to live in Centipede Ridge Cemetery. He also kidnapped Taoist boys elsewhere. Because he was seen by Wu Song holding Zhang Taigong's daughter in Centipede Ridge and laughing at the moon in front of the window, he was killed together with the Taoist boy
