"Great!" Cain shouted as he put the space ring on his hand and branded it with the [A.I. Chip Module].
As soon as Cain branded the space ring, the [A.I. Chip Module] generated a virtual image that showed the Wave Artifact's interior. It was not empty as it contained many Wave Beast's hearts, some healing drugs, and finally, a small gray crystal the size of a palm.
When Cain saw the gray crystal, surprise appeared in his eyes.
"That is a wave crystal. Even if it is one from the lowest grade, it is still amazing!"
Cain's excitement was understandable as wave crystals were indeed incredibly useful.
Most people in the Godsalyer Humankind Empire that failed to ascend to the true ranks of Wave Cultivators use paper money as currency. Still, for those who became Wave Champion, that was meaningless.
There are two main currencies in the Godslayer Humankind. One was the Imperial Military Credits backed by the empire; the other was wave crystals.
