The four Aarons managed to find some books worth their while after some hours of searching and the reading began. As if mimicking the original, they all sat in lotus position like old monks or sages only that this time they were not absorbing any strange energies or meditating, instead, they were reading.
What Aaron was reading about was not something usual. His interests had cut across history, culture, food and anything a person would need to know about their environment. He had been put at a disadvantage since he reincarnated in this world and he wanted to make up for it.
The first was that he reincarnated without the full extent of his ability and he was yet to find out the upper limit of what he could do. However, Aaron knew that he could not use his full power as the Demon King yet but he didn't know why.
