The appearance of this Abyss demon iron made Roy suddenly realize that the Abyss had minerals!
It couldn't be helped. You could not say that Roy was slow, and you could not force someone who studied painting and design to think about what minerals there were when he saw soil and rocks…
Now that he thought about it carefully, Roy had indeed encountered many demons with weapons. At that time, he only thought that they were weapons forged with their soul fragments, but he ignored the materials they used for forging.
Looking at the surrounding mountains and the ground beneath him, Roy was certain that there were some minerals beneath these layers of soil, but they might not be like Abyss demon iron.
It seemed that the gravity of the Abyss would become stronger with every level downward. If Abyss demon iron was only produced in the lower levels of the Abyss, it meant that the iron should be formed under high pressure.
