After dismissing the Stone Men, Archer turned to the last metal he knew, Orichalcum. It was reddish-gold, reminding him of copper. It was heavier than any others, but it didn't bother him before he stored it in his Item Box.
Once all the coins and ingots were stored away, he turned around and saw hundreds of barrels of a weird-looking gem. Archer walked over to them and picked one up, which started sucking his mana into it.
He watched with interest as the weird stone filled. It glowed all different colors, reminding him of the stars above before he stored it. Then he heard a voice behind him, ''Those are Manaheart Crystals!''
Archer turned toward Lucrezia, who rushed up to him with wide eyes. She took one of the crystals before explaining, ''You can use them to power weapons of war or a mana shield that covers a city.'' The blonde woman examined one as she continued, ''These are rare. You should use them all over your kingdom.''
