In the middle of the Dajing period, Lingxi, the princess of Yanhui County, fell in love with Xuanchen, a monk from Jingyun Temple, at first sight, and they stayed together for six years and became deeply in love. However, Buddhism has strict precepts, and Xuanchen adheres to the strict rules and excludes her. Under the oppression of the imperial power, the third prince forcibly married Lingxi. She could not bear the humiliation and died under the bodhi tree wearing a red wedding dress. Seeing the tragic situation, Xuan Chen's faith collapsed. He killed the prince, destroyed the precepts, and turned into a demon monk to guard the lonely soul. He only left the mournful cry of "Buddha has saved millions of people, why not save her?"
