This time Arthur stood on the side while watching in expectation what Agnus was doing. It wasn't anything new as the genius and young blacksmith put the cold purple ores inside the oven when the temperature was suitable.
Then he started to use a big fan to add more air inside the oven to keep the temperature rising. Arthur couldn't see clearly what was going inside the oven.
But he could follow everything happening via watching the energy changes. His eyes provided him this privilege. But he could only see the changes in energy and couldn't see what was going inside.
The first reaction between the ores and fire left a surge in power that startled Arthur. He felt this would lead to an outbreak of the sealed power inside the ores.
But as time passed on, and after ten minutes inside the oven, this surge calmed down and retreated to become just like specks of purple light shining around the ores.
