章 82: Remember to Include the Delivery Fee...

So… had he discovered treasure?

Primordial black crystal came primarily from the meteorites that fell from the sky. It had a very special quality and was a very difficult substance to detect through general methods of quality inspection. Furthermore, it was very easy for many merchants of raw materials to confuse primordial black crystal with ordinary black crystal.

Like with this stone ghost mask; from the quality inspection report which the customer service employee had sent, it was clearly written that this stone ghost mask was made from seventy-five percent premium black crystal and twenty-five percent elastic resin.

It was an ordinary mask that didn't serve any function, and the shop was completely unaware that the mask contained primordial black crystal, so it cost just six hundred HNY.
