Xie Qiao shook her head. She did not expect Shopkeeper Chang to be so naive at his age.
"It's good that you don't know." Xie Qiao smiled at him, but Shopkeeper Chang became even more curious when he heard that.
"Boss, if you have anything to say, just say it. I feel uncomfortable to see you hiding secrets." Shopkeeper Chang smiled.
Xie Qiao pointed at the bell at the door. "It rings every day. What do you think?"
"Strong wind?" Shopkeeper Chang hesitated for a moment. "It seems that there are times when there is no wind outside and it rings for no reason. Could it be that there is some kind of mechanism inside?"
Seeing Shopkeeper Chang like that, Xie Qiao grinned. "It's because that is the soul-summoning bell. It rings when a ghoul is near. When you hear it, there must be a ghoul coming up to the second floor as a customer, and I am listening to the ghoul's request from above."
