Steelmind hadn't been lying when he said the heat was going to be strong.
The heat that enveloped the metal at the center of the formation was so strong that even standing on the edge of the room made one feel as if his hair was going to light on fire immediately.
Being the person with the weakest cultivation base, the Alchemy God was doing everything he could not to let the heat affect him. At the same time, he was also adding to the flame, making it hotter.
Steelmind was the same, doing his best not to let the fire affect him. He had more to do here than even the Alchemy God.
While the two gods were used to being around flames, the Death God was not. She was doing everything she could just to protect herself from it. At the same time, she poured her Death aura into the metal, not allowing the Fire aura currently within it to permanently take hold of the metal.
