Charles kicked Zarlos away and said, "You dared question my strength this time. Does that mean you'll dare betray me in the future?"

The main material was refined Abyssal Demon Iron.
This material came from Abyssal Demon Iron ore mined in the outside world, smelted in searing magma, then hammered over and over by imps.
After repeated forging, the Abyssal Demon Iron became exceptionally tough.
