Seven years ago, Zhu Yimian reported that Ji Fanxuan's award-winning work was actually plagiarized, but left a self-report letter that night and committed suicide by jumping off a building. This was not only completely contrary to the original plan agreed by the two, but also put Ji Fanxuan on a "murderous" lock, but Ji Fanxuan knew that this was by no means the original story. After seven years of dormancy, Ji Fanxuan returned to his old place, hiding his true purpose, and stayed with Zhu Jiangmu (Zhu Yimian's father) in the name of an orphanage volunteer. The two of them each wore "masks" and waved knives hidden in the dark night to test each other. As time went by, after going deeper into the orphanage "Yougui", just as Ji Fanxuan originally thought, this was not a simple criminal network, and the black leaders involved were already connected to many high-ranking government officials. In the end, working with others, Ji Fanxuan obtained evidence that could completely burn him to death.
