The purple thorn token was letting out a dreamy and illusionary light.
The clerk stared at this token closely, his expression sluggish as he was lost for words.
After a long while, he came back to his senses and respectfully said: "Esteemed guest, please forgive me for being blind! Please wait a moment, I will go call the shopkeeper."
The shopkeeper was a middle-aged white fatty who ran in flustering when he heard a purple thorn token holder appeared.
He immediately bowed deeply towards Fang Yuan: "Esteemed guest, your presence brings light to this little shop!"
Fang Yuan pointed at the rocks he chose and said indifferently: "I have chosen some rocks, I will have to trouble you guys to dissect them."
The shopkeeper was stupefied when he looked at the rocks, how could they all be low grades?
I think it's pretty clear what he's doing now. (For those who said he uses a certain aura of a certain Gu)
