The people of the Ripple Mist sect had been sensing some abnormalities with the Sacred ground and thus the patriarch of the sect had ordered the elders to check upon it. The first thing they checked was the gate of the sacred ground and it was normal and thus the only other option for them that was left was the formation array instead.
Now, this was a troublesome matter for them. The formation array of the sacred grounds was set up in multiple parts. The main part of it that composed of over fifty percent of the formation array was entirely based in the sacred grounds itself.
And that was the part which could not be touched by the elders, and they could not send the disciples in either, as the time period of the sacred grounds opening was over as well. In fact, the only reason why they found out about this due to the disciples who had been chosen to enter the scared trials.
