Over 50 Years Of Isolation
When Lin Mu had roamed through the Ripple Mist sect he had heard from the many people there that the sacred trials will be held soon. And the most promising of disciples would be participating in it.
Lin Mu learned that the sacred trial would be held in a sacred ground which was nothing but a Minor plane that was located parallel to the location of this place. It was of course located in the lesser void, and accessing it required specific spatial coordinates.
But since it was a sacred ground of the Ripple mist sect, it was forever anchored to this location and would not move. Thus all they needed to enter it, was an access key or token. Once someone had this, the gate would let them in.
This gate could be in various forms, but Lin Mu did not know what it was for the Ripple Mist sect.
But after hearing that they were in the sect's Sacred Grounds, Lin Mu understood his previous illusion better.
