When Gravis saw Arc nodding, he didn't know what he should feel.
He had finally reached a power that would allow him to overcome this monumental challenge that had appeared insurmountable in the past.
Yet, it also meant that he would have to kill Arc now.
Gravis was so close to coming back home and being able to see everyone he cared about again. Sadly, this meant killing someone he cared about.
However, there was no other way.
This was an agreement between the highest Heaven and Gravis' father.
"Go comprehend the Law of Sentience first, Gravis," Arc said with a smile. "After you've done that, we can start."
"But give me a moment," Arc said. "I want to take care of some things first."
SHING!
Arc teleported away, leaving Gravis and Mortis behind.
Gravis sighed.
Gravis knew that Arc knew that there was a high chance that he would die.
