The small disk released a blinding light that was accompanied by a burst of powerful mana as it flew into the air. After it reached a certain height, it began to expand at a speed visible to the naked eye and the blinding light on it also dimmed.
The members of the group looked at the disk that had now grown to the same size as the top of the pit, blocking off the entrance. The disk was like a transparent barrier, which still allowed them to see outside, but a part of it was dark; tendrils of energy spread from this spot to the rest of the disk.
All of the members let out a breath of relief as they looked at the disk, they could feel the energy of a grade two mana core from it.
A grade two barrier. With this disk blocking the opening above the pit, the group below could relax for the time being.
The group didn't waste this time, every one of them immediately sat in cross-legged positions and began to absorb mana into their soul sea while resting.
