The heroine, after traveling through time travel, actually became the princess to be married to the fourth elder brother Yinzhen. The article is humorous and funny. Specifically, it takes the funny things that happened between the heroine and Four Four as the theme. The nine sons in history were only used as the background, not as the main story. This article may have many discrepancies with history, but it is not official history after all, so don't get too hung up on the dates in it.
