I'm not sure specifically what that particular fan fic is about as there could be many different interpretations. It might be about April O'Neil from a certain franchise (like Teenage Mutant Ninja Turtles perhaps) undergoing some kind of transformation. Maybe it's a physical transformation, or a change in her personality or abilities.
I'm not sure specifically what this 'Mo Fan x Mu Bai fic' is about without more context. It could be a fan - made story about characters named Mo Fan and Mu Bai, perhaps exploring their relationship, adventures together, or their individual character developments within a particular fictional universe.
A good Black Butler fan fic often has a unique twist. It could be a new type of supernatural element or a different take on the relationships between the characters. For instance, it might show a different side of the relationship between Sebastian and Ciel that we haven't seen in the original anime or manga.
Another good one is 'A Butler's Secret Mission'. In this fan fic, the butler undertakes a dangerous mission that tests his loyalty and skills. It's full of action and intrigue.
