Aldrian manipulated the divine iron, making it much softer but still hard enough for tempering. He didn't want to make it too soft for fear of damaging the divine iron when hammering it. First, he and Duke Valiard separated the true divine iron from the rock covering it. During this phase, they also extracted the impure elements from the divine iron.
After a long time, they finally separated the entire divine iron from the impurities. What they saw was a mesmerizing, pure, shiny obsidian material that emitted various natural laws. Cultivating near it would greatly enhance a cultivator's comprehension, tempting even Duke Valiard to cultivate on the spot.
