Two weeks passed before Aaron realised it.
He returned home two weeks ago and, in the past two weeks, has done nothing but enjoy life to the fullest. While his parents went on a feeding frenzy, he indulged them for the two weeks.
He understood that they went through hell when they heard the news about his disappearance, and that was not for a day or two. No, it was for weeks before he was able to leave the ruins and call them successfully.
So, in his mind, they earned it. They earned the right to do whatever they want to do.
Of course, that didn't mean he remained idle for two long weeks. He used the merits he earned to buy some rare books, which contained knowledge not readily available to everyone.
Even in the Academy's library, he didn't see these names.
Sure, there is an entire section called the Forbidden Section, which was open to only the professors and higher authorities of the Academy, who might have these books, but he can't get his hands on them at the moment.
