"This... is this a Martial Crystal?"
Han Xingye's hands were trembling slightly. The box contained a total of 20 crystal-clear Martial Crystals.
What did this mean? Even a second-rank dynasty might not find 10 Martial Crystals after turning the entire country upside down ten times!
On the road, sometimes buying high-value items with Xuan Silver is quite difficult, so people often use Xuan Crystals as a standard currency equivalent, with the average exchange rate being ten thousand Xuan Silver for one Xuan Crystal.
In other words, an ordinary household would have to save for a hundred years without eating or drinking to accumulate one Xuan Crystal. The concept of a typical family is similar to a three-person family on Earth with an annual income of 100,000 to 200,000.
People have seen Xuan Crystals being used as money, but using Martial Crystals as currency, Han Xingye had never heard of it until now.
