To continue my side-project to fix the annoying mistakes in past volumes, here is the major fixes on volume 3 and 4. I decided to add the text on the back cover of each book into the content now (previously I only did this for side stories books). With this new standard, I had also revised volume 1 and 2 again.
For Kindle users, I also make this awesome book available in MOBI format. Actually, you can simply do the conversion yourself using Calibre app, but I thought it might be easier for you if I make it available directly for download.
Finally, I am working on volume 14 right now and will release it as soon as it’s ready. I already have the raw PDF books up to volume 15.
