I have never posted a chapter in mangadex, but I thought there's a way to just replace chapter content without posting it as a different chapter??? Am I wrong?
Also, the fix still didn't really make sense. At least sentence wise. Even if the Emperor is actually using his name to refer himself as a third person, translating did not always have to follow the original word-for-word. In this case, since the readers did not even know (or more likely, didn't remember) the Emperor's name, more so for his nickname, it would be better for you guys to use "Me" rather than his name on that part. Or maybe use the Imperial "Us" that sometimes used for the Monarchs in Kingdom/Imperial stories such as this one.
