After leaving the Myriad Sect, Gravis focused on his next goal. The level six Laws were basically done, except for the Life Laws. However, since the Life Laws wouldn't be that useful to Gravis, he decided to leave them for way later. He would only focus on them when he was concentrating on the True main Laws.
So, Gravis focused on the level seven Laws, and the first level seven Laws he focused on were the three Laws of Pure Materials.
Gravis had been putting off comprehending these Laws for two reasons.
First of all, Gravis wanted to comprehend the Laws of the Elements before attempting the Material Laws. Comprehending the Elemental Laws first would make it far easier for Gravis to comprehend the Material Laws. After all, the Materials were all created by the Elements.
