LSLCCF
"Einstein's theory of relativity" Whoa there, Mr Author. Don't go bringing Hard Science into a novel with a Transdimensional Painting if you don't want people to point out the obvious holes in it's very logic!
Okay anyone else feel like the synopsis for this makes even less sense cause it has even less to do with what this first chapter is about? Sure if you define putting things into storage as a game the scroll could be a lower dimension game as in 2D vs 3-4D. Though really so far the MC has just found a strange form of storage ring in the shape of a scroll that is able to accept tiny sized living matter.
