A Dangerous World Of Cultivation

After adjusting his breath for a while, Fei Hong got up and walked to the furnace. He stretched out his hand to feel the temperature, and nodded slightly. *The fire is just right, and the fire is fierce.*

He turned around and fetched the red pot cauldron, opened the lid of the cauldron and threw the black iron stone inside it. Then, he put the cauldron into the fire. This was the method Wu Daozi taught him. If it were not for the top grade cauldron, he would really not be able to bear the rapid rise in temperature.

Soon, the cauldron made a cracking sound, and Fei Hong knew that the profound iron stone had begun to dissolve. He quickly found the needle-shaped mold he had selected from the mold rack on one side, and put it directly into the fire. 

By dawn, the black iron stone had been smelted in the cauldron for nearly three hours.
