Three hours later, Xu Fan looked at the shining clean iron plate and scratched his head, as it seemed to have no effect.
The only difference was that the runes on the iron plate seemed clearer now.
"Glowing Rune, Tiger Power Rune, Quicksand Rune?"
"What's the connection between them?" Xu Fan looked at the iron plate and said with doubt.
At this moment, Xu Fan took out a rune pen and began to draw on the iron plate.
"Maybe I just need to draw runes on the iron plate to unlock its secret."
The iron plate, as tough as a magical treasure, was easily carved with Xu Fan's runes.
Right after Xu Fan finished writing the runes, a shadow of an hourglass appeared on the iron plate. Judging by the speed of the sands, it was about half an incense stick's time.
It gave an inexplicable feeling that this was a secret treasure that tested an artifact refiner's rune proficiency.
