Well, at the end of the first volume, here, let me explain it again. The second volume was cut by tens of thousands of words and underwent a major revision. Starting with Chapter 10, Chapter 11, Chapter 12, and so on, each chapter name will be followed by a '(Revision)'. If the book friend's mobile client does not show it, or the chapter layout is chaotic, you need to re-add the bookshelf again for the display to be normal.
