I once edited chapters from 1 to 7 when I started writing this novel and I will do similar things in the future.

If you ever see things like "(Improved version)" or "(Revised version)" besides the title of a chapter, here are their meanings.

Improved version.- This means that I greatly changed this chapter and added at least 400 words.

Slightly improved version.- Similar to the previous one, but with a fewer count of new words.

Currently being improved.- Meaning that I will make it better in the near future.

Previously improved version.- I once improved this chapter before, so you might have read the newest version already.

Revised version.- If an improved chapter has many writing errors or plot holes, I will correct them and this will appear beside its title.

Final (or Last) version.- This one will probably never appear. At least it won't until I have finished writing this novel.
