After a satisfying meal, Gu Wen asked, "Master, what should we do next?"
Without hesitation, Qingcang replied, "We'll go and watch the street performances. I remember that back in my day, the tricks used by mortals were often just deceptions and conjuring spirits to dupe others. Now, it seems that the charlatans still exist, but they've managed not to harm anyone. The changes over the years are indeed wondrous."
Then, as if something else occurred to her, she murmured to herself:
"There are also those carvings made from broken stone that look quite valuable. Here, a bowl of rice costs ten coins, a thousand coins for an ounce of silver, yet such a piece of stone can cost dozens of ounces."
"Why is that?"
Naturally, Gu Wen knew what she was referring to by 'broken stone', and he answered, "The price of an item is assigned by people. If a significant number of people consider it valuable, then even a worthless stone can be worth a fortune."
