Returning back to the present where Aurus had just recently killed the unnamed boss of the Greater Experience Haven, obtaining another OS Point for his use.
Feeling satisfied with the effects of the newly obtained Battle module from the [Artificial Intelligence] option he unlocked from the Existence Evolution System's OS, he decided that it would not be a waste for him to allocate another OS Point to the Battle module. Heck, even if he decided to allocate all of the points he would obtain from killing bosses to the Battle module, allowing it to max out, he would not even have a tinge of regret!
That's how reliant the Battle module is!
"Upgrade [Artificial Intelligence: Battle Module]," Aurus commanded to the system, without even a shred of hesitation.
Ding!
'Are you sure you would like to upgrade [Artificial Intelligence: Battle Module] to Level 2/10? This will cost you 1 OS Point!'
