Four days passed by since I had entered the Library of Hermes, and in the four days, I had only taken eight hours of sleep. I am at Emperor Stage. If I took a sleep of two hours daily, I would be able to study it with my maximum efficiency.
'It's a good thing, Professor had brought me to this wonderful library; otherwise, I would have made quite a huge mistake if I had gone with that method,' I said to myself as I closed up another book.
Before, I had planned to create a core with a method derived from the twins' core formation and tidbits I had gathered from the books I read. If I had done that, I would have done myself great harm; there were huge chances I would have died by an explosion of energy.
There is a huge difference between the Cosmic Core and the Core of the Celestial Inheritance. One form naturally while the other needed to follow a specific method.
