"Come on, croak for Grandpa." Immortal had the time of his life as he smacked the face of the Regression System repeatedly. Instead of defending against the opponent's attacks, he traded blow for blow, focusing his entirety on offence.
He didn't simply attack the Regression System but instead went out of his way to target its face. The Regression System was a giant mass of Mental Energy akin to a quasar that pulsed in the void. But the region where its Core Skill existed could be considered its brain, heart, etc.
And in human terms, the exterior of the head that faced the opponent during a fight was the face. Immortal targeted that like a leech even during situations where he gained a direct path of access to the Regression System's Core Skill.
Once he kept up with the process enough times, even the Regression System was triggered. Mental Energy swirled in its body like a storm as it latched onto Immortal and ate away at him.
