Despite being overpowered compared to the current levels of the tower, Miya continued pressing on through each floor, with Petne watching from the sidelines, enjoying her maniacal grinding.
He didn't wish to fight—not when she was having fun and collecting as much life force from the beasts as possible.
All she left behind were the cores, which Petne had been collecting for some time.
He wasn't picky about which realm the cores came from; every beast core would be a big boost to the empire's armies.
All the women leaders were collecting these cores as well, as were Petne's women, given they had little use for them personally. With a war looming on the horizon, this was necessary preparation.
At one point, Petne thought he might be turning into a hero. After all, he was contributing so much to everyone's growth with his own resources.
