Any novels that take place in "Boundless Universe"?

Hi, I have noticed a lot of posts about Lord Fifth so I read about it on this wiki: 
http://wiki.wuxiaworld.com/index.php?title=ISSTH:_Lord_Fifth ;

There is a mention about Boundless Universe and All Heaven`s Universe.
It seems that Boundless Universe is some kind of higher realm/plane?
I have noticed that few stories takes place in "fake" universes? 

Renegade Immortal(I took a look at few spoilers which explained a bit about this "fake" world or something), ISSTH and possibly other stories. 

I need more information about that. 

Thanks

Not too sure, but I'd say no. At least for now. Maybe later we will se something.
