"Demon Iron, of course I remember. It's said that this thing is a very precious mineral from another plane. Back then, Grandfather killed a Demon Monarch and obtained it from his Storage Ring. Why, does the old Prophet want Demon Iron? That's impossible; it's our family's heirloom treasure."
Barton Nock snorted coldly, his expression becoming sullen.
"You need to change your temper. You're not even half as good as your daughter. I haven't finished speaking yet. Listen carefully, we've had the Demon Iron for so many years, and I've been burning it with earth fire, at least an hour every day.

Barton Nock knew about this matter too. During his father's generation, the family hoped to refine the Demon Iron into an Immortal Artifact. But no matter what method they tried, they couldn't melt the Demon Iron.
