During the Xuanhe period of the Northern Song Dynasty, a sensational poisoning and murder case occurred in Yanggu County. The victim was Wu Dalang, the brother of the tiger-fighting hero Wu Song, and the biggest suspects were Ximen Qing and Pan Jinlian. Wu Song was determined to avenge his brother. After finding no way to appeal, he resolutely resigned from public office and worked hard to investigate and collect evidence. The case is shrouded in mystery, and everyone involved is questionable but none can be identified. Wu Song once hunted down Pan Jinlian and fought against Ximen Qing many times. It was not until the end that the authenticity was revealed and the great revenge was avenged. This is a purely fabricated story with a time-travel component, and the time-travelers are only witnesses. The stories about Ximen Qing, Pan Jinlian, Wu Song, Wu Dalang and Wang Po in "Water Margin" are well-known to every household. The author has no intention of changing the historical classics. He just wants to change the perspective to understand the complexity of human nature and the love and hatred between men and women. This is an eternal theme of life, and everyone has different interpretations and opinions.
