The young man responded with a "Yes!" and quickly approached the stall, casually tossing out a piece of crystal stone, saying to the boss, "I'll take all of this!"
The boss received the crystal stone with an ecstatic expression, nodding furiously like a pounding drum, abandoning the stall entirely and leaving immediately with the crystal stone.
Ye Chen watched the amber-colored crystal stone in the boss's hand, a flash of intrigue in his eyes!
This crystal stone was emitting extremely dense and incredibly pure spiritual energy!
However, Ye Chen had never seen it before, so he couldn't help but ask, "Fairy Xuan, what is that crystal stone?"
Xuan Han Yu replied, "That crystal stone is called Xuan Crystal, the highest grade currency in the Outer Realm. Xuan Crystals are divided into nine grades, with Grade Nine being the highest and Grade One the lowest. With each grade increase, the concentration and purity of the spiritual energy within the Xuan Crystal greatly enhances!
