Angel looked at the display case curiously.
Its surface seemed to be made of some special Crystal Shell that could block mental power.
He had noticed this earlier when he was observing the blue velvet cloth. He had seen some strange patterns on it, but in the blink of an eye, they seemed to vanish again. Since he had not seen them clearly, he had tried examining them with his mental power, only to find that it could not probe into the display case at all.
Since he could not investigate it, Angel simply asked outright.
"What is this?"

And this display case had been crafted from a Level 3 treasure, which was enough to show just how precious it was.
Yota pointed at the Psionic Display Case and continued, "As for the blue velvet presentation platform inside, you can think of it as a small teleportation platform..."

The glow came from an array on the velvet.
Angel focused his eyes and saw that this array was an old acquaintance.

Within the Crystal Castle, everything related to the Electric Light Hexagram represented teleportation
