I wanted to merge these files by converting .docx adjusting fonts, re-creating as pdf, and merging with bookmarks. When I converted Part 1 Calibre and AVS Document Converter returned non-readable combination of characters. Pdfgear converted to doc but distorted the initial font and removed spaces between words. I just saved webnovel version as html, saved as docx, removed chapter 2, added 2 illustrations from the initial pdf file, inserted spaces between words (yes, MS Word automatically underlined these words in red), and italicized some phrases as in corrupted Part 1.
Therefore, to complete this merging I would prefer to have original Chapters 1 &2.
