At this moment, the instruments inside the detection chamber emitted periodic alarm sounds, Elder Lu turned her head slightly to look, "There is some radioactivity, but the danger level is not high. However, with this, it should no longer be any Secondary Stone."
"Why do you say that?" Xu Huo asked.
"Although Secondary Stones are diverse, the ores that can pollute their surrounding environment are not listed among the prop raw materials, nor are they categorized under Secondary Stones, but are collectively categorized as polluted ores." Fang Jie explained on behalf, "Such ores can be made into props, but their pollution is difficult to control. Long-term use can inversely affect the owner, and the Game Government has regulations explicitly forbidding polluted ores from being used to create props."
To put it simply, these are unqualified prop-making materials. Due to their polluting nature, general Artifact Makers wouldn't risk taking them on.
