First Friends
William spent another week reading in this regular library. When he looked at it at the end of the day, he had run out of soul stones. He wanted to enter the library inside the tower, but he did not have enough money. Even though he had hundreds of thousands of soul stones in his ring, he couldn't spend it as he wanted, or someone would be watching him. The biggest reason he wanted to enter the library in the tower was that he had the basics. For example, basic information about the elements. It's no secret that these are in the library.
