Yuan Ming's gaze shifted from the Mid-grade Spirit Stones in the man's hands to the two black jade plates, and he paused for a moment, looking slightly puzzled.
"Young friend, this must be your first time trading runes, right?" the skinny old man asked tentatively.
"Cough, indeed, I have not dabbled in this area before," Yuan Ming coughed lightly, admitting with a bit of embarrassment.
"Hehe, it doesn't matter. There's always a first time for everything. This is a Rune Jade Plate, specially designed to record runes. It can capture the entire process of the rune's formation for future reference. You only need to gather a wisp of mana at your fingertip, and trace the rune onto it," the old man chuckled, giving Yuan Ming an encouraging look while secretly rejoicing in his heart, having already categorized Yuan Ming as a profligate scion secretly selling his family's rare runes.
