"City Lord, here is today's account book, please review it."
In a secluded courtyard behind the black market, the owner of the market, the Cloudy Elder, respectfully handed an account book to Wei Cheng.
Wei Cheng didn't bother to look at it, just waved his hand, as he had all the relevant prices memorized.
The price of rough Mysterious Iron is the lowest, about a Spirit Stone per hundred tons.
Therefore, given the chance and time, those who understand the trade refine roughly hewed Mysterious Iron into Mysterious Iron Ingot using mana.
At this point, the market price is about one Spirit Stone per ten tons.
Mysterious Bronze is no different than Mysterious Iron, both having the same price range.
Worth mentioning, the fifty million tons of Mysterious Iron and Mysterious Bronze that Wei Cheng brought back to Earth last time were all refined.
In other words, just these two types of assets could net Wei Cheng ten million Spirit Stones if sold on the market.
