Leon truly felt that he was finally entering the Overpowered Genre now. After all, he could level up faster by using the Energy Orbs and could increase his battle prowess by making all of his Skills reach Max Stage.
Lastly, he also had time dilation, meaning he could spend a lot more time in the Dungeon improving his skills and becoming stronger.
'The problem is my enemies are also strong as hell. Every single bastard in the Primordial Expanse is a true monstrosity to the core. I can't let this get over my head. I'm still a weakling.'
He once again poured cold water on his thoughts because he knew himself well. With all this potential of becoming overpowered quicker than others, he would surely get arrogant.
It was just a bad habit that he couldn't let go.
