So, 3 books with the number 6 in the title, with the number 7 added in with after reading them for the first time in the locked library section. Yeah, still don't get it.
But it sounds like you found the solution?
Well, whatever the solution was, I didn't get it.
It was 7. Sorry. :/
Like, just the number 7? The 6 other sections are for nothing?
