A thunderous crash shook the room. A spray of powder burst from the heavy silver. This was proof of the tremor effect at work! It could vibrate impurities out of a metal!
Although the result was simple, this wasn't something that just anybody could do. In order to bring out the full potential of this effect, a blacksmith needed to possess overwhelming strength, a firm foundation of soul power, immense spiritual power, and a deep understanding of the metal they were forging. If the blacksmith did not fulfill even one of these requirements, it would be impossible for them to use tremor effectively. In fact, the tremor effect could even become a disadvantage.

As he watched the boy in front of him forge away, Zhen Hua's amicable smile gradually grew concerned. A trace of doubt flickered in his eyes.
