"Forty high-grade mana crystals," the strong man besides the tenth master said incredulously.
Aur nodded in response.
The tenth master frowned slightly at the strong man's reaction, but quickly regained his composure and addressed Aur. "Distinguished guest, since you want to exchange for forty high-grade mana crystals, I might not be able to fulfil your request."
Aur stood up, ready to leave. "Forget it, then. I will go to the second master."
The tenth master quickly interjected, "Wait, wait, I didn't say I will not buy it. It's just that we currently don't have enough mana crystals to exchange for forty. Please understand our limits and give us half a week of time."
He spoke anxiously, the business composure he had learned fading in the face of wealth and greed.
Aur stood up from his seat and replied in a simple tone, "Too long."
