Yu Qinqin paused for a moment, then continued, "But not long after, they returned, asking to split the stone again. At that time, I and my father were not in the shop, leaving only two clerks. They didn't think much about it and didn't realize they had swapped the stone, so they split the stone as they requested. It was only then they found out it was cobblestone, and this is how the trouble began."
Jingrong narrowed his eyes, a cold gleam flashing as he asked, "The stone was swapped around? Are you sure they swapped the stone and it isn't our fault?"
Yu Qinqin nodded in quick succession, her expression quite anxious, "It definitely isn't our fault. Although our business is not as good as it used to be, we've always operated honestly. We wouldn't engage in such a deceitful act."
