The business of trading in human heads is currently the hottest speculative enterprise in Revodan.
The formal name of the human head vouchers is [Empire Calendar 559 Iron Peak County Military Merit Land Exchange Certificate]. This name is indeed too awkward to utter, and everyone's first reaction upon hearing it is: "Huh? What?"
Thus, in most circumstances, people unanimously use its colloquial name—human head vouchers.
There is no public trading exchange for human head vouchers, and there is no universally recognized real-time price.
However, whether it is the actual heads or the certificates, apart from the initial period of fluctuating prices, for the rest of the time, the prices have generally risen, up to today.
After the results of the "Blood Mud Battle" reached Revodan, those speculators who gambled and acquired the heads immediately have, at the very least, doubled or even tripled their worth.
