Su Yu was in a daze. Could it be that his comments had unintentionally offended the shopkeeper?
"Do you know who refined this sword?" the elderly man said. He was probably in his sixties and wore a bitter expression.
"I don't know," Su Yu said, shaking his head calmly.
The old man hummed through his nose. "Ignorant and disrespectful! There is only one top-grade crafting master in the Heaven Treasure Building, and he is Master Lin!"
After pondering for some time, Su Yu questioned calmly, "Am I supposed to know him?"
"What an ignorant kid!" the 60-year-old man berated him furiously. He clearly felt as if he had been humiliated. His voice was extremely loud, and it attracted the attention of several onlookers. When they noticed the old man, a number of strong martial artists revealed expressions of veneration.
