Gravis felt incredibly satisfied. In the last 38 years, he had watched as Ferris understood one Law after the other, while he hadn't understood even a single Law during that time. It had been very frustrating at the start, but as Gravis came closer to his goal, he realized that his progress wasn't slower than Ferris', well, as long as he ignored the level two and level three Laws Ferris managed to understand.
By now, Gravis understood that one's knowledge about the world couldn't fully be defined by the amount and levels of Laws one understood. Ferris had lived for way over 3,000 years, yet he hadn't been very powerful for a level one Emperor. Did that automatically mean that he knew less about the world than more powerful level one Emperors?
