Nux knew he couldn't completely reject the system, at least right now he couldn't.
And this is why, he decided to take small steps.
Slowly and steadily, trying to get out of the System's influence.
And today, he took the first step.
He created system abilities on his own.
With this new step, however, he now faced a whole new set of problems.
As he created the System abilities on his own, according to the System, he now didn't 'have' those created abilities.
In his stats, the section where his abilities were shown, the abilities he created weren't mentioned, now this raised a question, how was he supposed to raise his ability level if the 'button' to click on it doesn't even exist?
It wasn't a matter of System Points anymore, even if he had enough, there was no way he could 'pay' to upgrade his ability.
