Each of the gray Chaos Gems seemed like a dense and contracted pocket world. They were likely the group of Chaos Gems that Yi Yun encountered when he first entered this spatial plane.
"Oh? This is…"
Yi Yun's eyes narrowed, for he discovered a pure black gem the size of a finger close to the few Chaos Gems. The surrounding Chaos Gems appeared to revolve around the black Chaos Gem like planets around a sun.
This scene made Yi Yun draw a deep breath. Just like the way Spirit Jade had different grades, Chaos Gems had grades too. The finger-sized black Chaos Gem had to be of a higher grade than its surrounding Chaos Gems.
Chaos Gems which were condensed at the birth of the Universe had very different energy levels as well.
