"Alright, start folding the steel billet and continue hammering," the old man said.
"No, folding an uncleaned steel billet will allow impurities to get in," Xue Dili said. Though it was his first time forging, he used to be a master swordsmith.
"Do as I say, a Magic Swordsmith and a Magic-guided Swordsmith are two entirely different schools," the old man explained, although Xue Dili didn't understand.
Xue Dili immediately folded the steel billet and, through repeated hammering, discovered the principle: the impurities being folded in were actually volcanic lava and energy.
With each strike, this Holy Sword would gain an additional layer of volcanic lava protection.
Xue Dili thought of his first enemy, the Witch Demon King, the undead who feared volcanoes.
If he had had this sword back then, he could have extracted the Witch Demon King's marrow and pulled out his skull.
"Keep folding, keep hammering!" the old man's voice continued to ring out.
