Inside a small apartment complex, a man with dark tired eyes stared at scattered pieces of chips and micro metal swirling like liquid around it.
"Hush!"
He rubbed his eyes and sighed.
"This barrier is just too hard to overcome, no matter how much I try, I can't seem to find a way to advance this orb sphere to 5-Star level armour protection."
Up to 4-Star, normal metals blended with ductile metals like harmonium, grey granite and others metals was enough to cut.
But to go beyond that, one needs to have metal that has enough molecular binding force that can resist the inner destruction caused by aura.
Repeated hitting with great strength wasn't enough to break low-level metals, but it becomes difficult when it comes to aura that is purely mystical energy.
The aura infused with mana seeps inside the metallic structure due to being a pure form of energy and distorts the atomic structure breaking down the bonds present at an atomic level.
