I Became a Passerby in the Novel "The Dragon King"

Lu Ming traveled to a different world and became a passerby. There was a big difference in the development of literature, so he became a literary scholar. When he graduated from college, he had become a billionaire. Suddenly I found that I was traveling through a novel about the Dragon King Descending the Mountain, and became a passerby. However, because the female protagonist I rescued when I just traveled through time took the initiative to confess her love, she was suppressed by the protagonist and the villain. At the same time, the protagonist and the villain have been tit for tat. So he accepted the confession of the female partner, and then let her join the business world to perform freely. As a result, the fate of the hero and the villain also changed.
