Rules of Astral Travel; Approaching Confluence Period (2)

"The principle of the shuttle device is to pass through the Astral Membrane and send things into another universe. The Astral Membrane is a little similar to a different kind of supermarket barcode. Its function is to filter everything from the outside world and restrict abnormal information that doesn't belong to one's own plane. Therefore, many technologies and items can't travel through it…

On the other hand, living beings don't seem to be in the filtering category. However, if the superpower system conflicts, although the abilities that they already have will not be deprived, the related abilities will be suppressed and might even be unable to activate."
