In the end, it transformed the energy into threads of pure power that merged into the airflow inside the cave. The Heaven Opening energy within was now about ten percent richer than it had been half an hour earlier.
Su Qingyan walked to the edge of the barrier and lightly touched the translucent energy buffer with her fingertip. It felt warm and smooth, as if she were touching a flowing film of water. "The laws governing this buffer are very unusual," she mused. "It doesn't block our perception of the outside, yet it filters out all harmful energy.
