As Feng Yuan rhythmically knocked on the gemstone, a green hologram appeared before everyone, with a red dot marking a point in the midst of a dizzying array of 3D channels.
"This thing is probably a map, but it's not complete. You could say this gemstone is just a part of it, or maybe it relates to the final passage through the Earth Maze?"
Looking at the 3D map, Feng Yuan muttered. The use of this thing automatically conveyed itself to him when he got hold of the gemstone. It contained powerful natural energy, and Feng Yuan estimated it was a rare item without any rank restrictions.
As for the effect, it mainly enhances the power of Spirit Beast Ultimate Skills related to natural attribute energy. Of course, this enhancement is related to the energy level inside the gemstone; the effect is maximized at Elite Level strength. Beyond that, as the gemstone's energy limit is fixed, the enhancement will be relatively diluted and weakened.
