About Updates to the Extra Chapters and the Main Text

Two days to update the main text, two days to update the extra chapter.

I know the 30k thing is popular, but some people like to read the 40k main storyline, and I also have to compile the outline of 30k.

It is impossible to open a new book for the extra chapter, because it is an extra chapter, and the protagonist will not encounter as many troubles as in the main text, it is just a happy IF line.
