Capítulo 839: Chapter 839 – Core

Gravis had big plans for the next set of Laws. These next ones would substantially increase his Battle-Strength while not needing any extra Energy usage.

The first Battle-Law of the Element of Core that Gravis wanted to comprehend was the Law of Core Manipulation.

This Law would allow Gravis to manipulate metal and its associated matter with more ease. It sounded rather simple, but this was the Law that would combine all his other Core Laws.

As always, Gravis seemingly understood this Law in no time and went directly to the next Law Comprehension Area.

The next one was the first Law that would increase Gravis' power by a lot, the Law of Core's Sharpness.

This Law would allow Gravis to manipulate metal and its associated matter in such a way that the cutting edge of the metal would become that much sharper.

What made this Law so special?

Gravis didn't need to use this Law all the time. 

Why not?
