The Demonic Spirit laughed crazily for a while before stopping to say, "You're so ignorant to call me useless!"
His voice had hints of anger. How dare Su Mo claim that the Billion Demonic Sword is useless?
"Isn't that true?" Su Mo was incredulous. He now had nine Natal Spiritual Swords, so the Billion Demonic Sword had no use to him.
"Humph!"
The Demonic Spirit scoffed coldly, "The Billion Demonic Sword is more powerful than you can imagine. My power is not even at a tenth of what it was because my spirit was damaged."
"Really?"
Su Mo smiled and asked, "How powerful were you at your peak?"
The strength of Divine Weapons with Item Spirits usually depended on the strength of the spirits.
Perhaps the Billion Demonic Sword was truly exceptional at its peak, since it was a weapon with an Item Spirit, making it much stronger than regular Imperial weapons.
