How to edit this specific margin in the book I have been editing... The red arrows in the pictures below....because the TOC of this book is kind of long so it goes to the next page, and I believe that the space in the first TOC page could be better used.
I have seen some topic about SIMILAR questions, although they talk about external margins, side margins or space between items... which is not the case.
Is there a way to reduce the red arrow margin?
If necessary, I can add a MWE as well, but I am not using anything different than \tableofcontents* in this page.

Note that I've placed the\setlengthand\chapterinside a group, so it only affects that chapter's adjustment. – Werner Jun 15 '16 at 17:30
