With time, Thunderous Battle had gained further understanding of Heartless Iron and learned why Heartless Iron had a slightly higher rate of success in refining equipment compared to normal people.
Heartless Iron's ancestors were famous ironsmiths. Even though there was no longer any creation of weapons during peaceful times and there were more creations of machinery through the use of technology, the people in Heartless Iron's generation still inherited the craft. It might not be much, but he had inherited the unique method to create weapons as something of a hobby.
He was known as the Iron Striker in town.
It was because of indulging in the art of smithing for a long time that Heartless Iron knew the feeling of refining all sorts of metals much better than other ironsmiths. He had a much better instinct compared to the others.
It was what allowed him to avoid many risks. Hence, his success rate when refining equipment was higher!
