The protagonist is a princess who got married. After getting married, in order to grasp the trends and military secrets of the Huns, she pretended to cheat on the leader's brother. Later, she committed suicide due to some things. After her death, she was taken into the underworld by Black and White Wuchang, crossed the River of Forgetfulness, and walked across the Naihe Bridge. She accepted it because she was a princess. After interrogation by a group of officials from the underworld, they learned the secret of the six paths of reincarnation. They exchanged three hundred handwritten scriptures of the "Qing Jing Sutra" for willow branches that allowed them to ascend to the Avalokitesvara Bodhisattva without drinking Meng Po soup. Later, when they woke up from the dream, they found that they were listening to an audio book that could recall their past lives.
