Wu Zhi transmigrated into a book. In that story, a toad gets lucky enough to marry a swan, only for the swan to cuckold him and then poison him to death with her lover. But after transmigrating, why is everything so different? The plot is full of bugs, and everyone is out of character. Most importantly, wasn't that guy supposed to go after his wife? Why is he sucking up to him every day?! Have you heard? Wu Dalang and Brother Ximen have gotten together. (I made this up. It has nothing to do with Water Margin.)
