"What on earth?? Purity?? You mean sharpness, right? What are you trying to say?" Shi Wei looked at Jifeng in confusion; he had no idea what he meant by purity.
Jifeng took two purple, blade-shaped objects out of his template and tossed them to Shi Wei. "I just went and got two more pieces of Amethyst Stone, refining one down below and the other in the cauldron. The resulting Amethyst Iron had completely different levels of purity. Amethyst Iron is extremely difficult to extract from Amethyst Stone, and the purer it is, the sharper the blade."
Shi Wei caught the blades. One of them refracted a much brighter purple light and felt significantly lighter and thinner. He threw both blades into the distance, controlling them to collide with each other. One of the blades was sliced straight through the middle, while the other suffered almost no damage.
