In the end, Nathan decided not to talk about it for the time being. Vivian respected his decision because she, too, didn't want to think of the possibility of her killing her own student.
Meanwhile, Charlotte was helping him in the magic circle creation.
"So, you mentioned earlier that you had a few magic in mind. Have you heard of them before?"
Nathan nodded. "Well, not all, but a few."
"I see. It appears you have used the time element by using that contract."
"Yes. It's just that I end up having to bear the side effects as well."
"Can you tell me about it?"
"The magic I plan to use is Acceleration. It allows me to accelerate my body's process. This is not the same as a speed increase. It's true that my speed will also increase, but more importantly, all my thought processes, conjuring my ena, and other stuff related to my body will increase in speed. This is what I mean by Acceleration."
