While Xu Shan was looking at the broken sword, the Shopkeeper kept his eyes on him.
In fact, the shopkeeper himself was slightly surprised. This was his shop, but it was his first time seeing that old rusted sword. He was convinced that the broken sword was never there the last time he saw it.
He scratched the back of his head, wondering if he was getting old and forgetful. There was no way something like that would appear out of nowhere.
"Must be some worker who placed it there," he thought, finding a justification.
Still, the Shopkeeper couldn't shake off the feeling that there was something strange. It was weird that Xu Shan had gone straight for that broken rusty sword, instead of all the shiny and powerful artifacts.
Nevertheless, amidst all the peculiarity, he made the conscious choice to focus on his benefits only. If he could sell that old Sword, then it was only good for him, even if he had to lie a little.
