"How much is it?" Aur asked, looking at the watch with satisfaction.

"About that, you see, since these equipments aren't mass-produced, their price is very high—"

"Get to the point." Aur rubbed his ears, looking at the butler with an annoyed expression.

"Very well, young master, it will be twenty middle-grade mana crystals," the butler said with a smile. However, Aur frowned when he heard the price.

"These little devices cost this much?" Aur said with a little disbelief.

"You know it is made up of premium—"

"I will take it for fifty low-grade mana crystals," he interrupted the butler with a smile.

"Isn't that a little greedy?" the butler said with a business smile. This kid was too greedy.

"Forty low-grade mana crystals," Aur replied.

"This kid is a tough nut to crack…" the old butler rubbed his forehead with a frown on his face.
