I just reported the following to MangaDex using the report button:
Chapters 32 through 35 are actually chapters 31 through 34. This can be seen on the opening page on each chapter. Chapter 36 is actually chapter 36, based on the original Japanese left in the uploaded chapter. Thank you.
@Liqiudxlax I think it's because it may not be the most ambitious story but at the same time it's not the most boring. I enjoy the character interactions and new magic stuff. I think it also helps that each chapter is pretty well contained. They usually have over 40 pages and the plot is moving at a decent pace. Other mangas would take 70 chapter just to do what this one has done in 35.
