"It's an easy one if you have enough time to think about it," he said before adding, "it took me roughly one year to figure it out."
"And?" Arthur tried to remain as calm as possible.
"What makes a system? Or to put in better words, what gives the system power to operate?"
John's question startled Arthur who wrecked his mind without getting anything as an answer.
"C'mon, don't tell me you were using a system without knowing how it operated… or you never had a system before? Damn!" John couldn't help but hysterically laugh.
"I've a system already," Arthur gritted his teeth so as to not lose his cool, "but I never thought about asking for the source of his energy."
"Then you must be a lousy kid, one of those spoiled brats coming from arrogant clans."
