"Is this what you threw to me?" Catherine pulled out the card that had once saved her life, gently flicked it, and the card vibrated to make a crisp sound, "Is this the identity mark of the goblins?"
"Quite delicate, isn't it?" Pannis also pulled out a card casually, touching the uneven surface of the crystal card and said, "I heard a goblin once recall that during the glorious period of the Goblin Empire, they had such crystal cards as their identity markers. There was also a corresponding device that could read the detailed information of the holder by inserting the card into it. But more than ten thousand years have passed, and the corresponding equipment was damaged because it was not made from goblin's special alloy. To date, no usable reader has been excavated, although there have been over a dozen of these cards unearthed. It's just that no one thought it had such a judging function."
