The immense power was gradually absorbed by Charles.
Complete laws, one after another, were captured and analyzed by him.
During this process, Charles even felt that he might be able to ride the momentum and break through to become a fifth-ring wizard.
At this stage, wizards needed to rely on analyzing laws to gain power.
But after analyzing them for some time, Charles ultimately gave up on the idea.
He thought, It's still too much of a stretch. I'm afraid I won't be able to seize this opportunity.
Thus, Charles gave up the possibility of becoming a fifth-ring wizard in tandem with this stage of advancing to Devil Lord.
He began focusing on strengthening his physical power and raising his demon rank.
The absorbed power of laws was gradually filled into his body.
Meanwhile, at Millstone Fortress.
During Charles's breakthrough, waves of powerful aura pressed down on many demons until they could barely breathe.
Zarlos lay sprawled atop a spired tower, staring at the central tower where Charles was located. He thought, That aura... it's that old bastard Charles!
What is he doing? What is he doing?!
No, don't tell me he's about to become a demon lord?
How long has it been since he became a Greater Demon? No way!
At that moment, Zarlos seemed to see a future of utter darkness awaiting him once Charles broke through and became a demon lord.
Zarlos thought, I can't let that old bastard Charles succeed in breaking through. Otherwise, how will I ever have another good day?
As he spoke, he prepared to take flight.

Bruce was currently clad in a Devil Baron's armor and wielding a massive axe taken from some unfortunate soul.
They were all fourth-tier pieces
