Resembling gold but not gold, the purple hue carried a tint of bloodiness within it; such a trace looked like threads of blood encased in purple. Xiao Chen gazed at the piece, roughly the size of a human head, in his hand.
However, besides the bloody threads, this piece of purple gold also had spotty black impurities embedded within it, representing the imperfections in the purple gold.
The purple gold was impure!
This was also why Xiao Chen had not immediately refined it into his body. Purple gold forged battle bones, but impure purple gold, if incorporated into the battle bones, would cause small holes throughout them like a honeycomb, not only failing to forge the bones but actually making them brittle, producing the opposite effect.
Refining this purple gold to purity was no easy task because purple gold feared no tempering, unless subjected to an immensely great power.
