Ling Pengyun was extremely interested in Sui Jin True Person's proposal that by handing over thirty jin of Treasure Iron, one could obtain a Spirit Treasure Prototype.
This method was essentially a disguised commission to forge a Spirit Treasure Prototype, except the success rate was around thirty percent.
However, forging a Spirit Treasure Prototype was difficult to begin with. Maintaining a thirty percent success rate was already quite good.
Moreover, Sui Jin True Person's terms came with a guarantee. Forging was his responsibility, but so long as thirty jin of Quasi Fourth Rank spirit iron were handed over, one would definitely receive a Spirit Treasure Prototype.
Most importantly, those thirty jin of Treasure Iron did not even need to be of the same kind. Mixed varieties were acceptable, which was countless times easier than searching for thirty jin of the same type of Quasi Fourth Rank Treasure Iron.
Taken together, this trade of handing over Treasure Iron in exchange for a Spirit Treasure Prototype was exceptionally favorable.
At the very least, in the outside world, one could forget about finding any high-grade Weapon Refiner willing to forge a Spirit Treasure Prototype from thirty jin of mixed Quasi Fourth Rank Treasure Iron.
Although quite a few Spirit Treasure Prototypes and magic treasures could be forged with different kinds of spirit iron as their core materials, they still required specific configurations of spirit iron. It was not as though any spirit irons could simply be melted together and used for forging.
Forging magic artifacts was also a highly rigorous craft.
This Martial Uncle-Grandmaster must have immense confidence in his forging skills. At the very least, the success rate for refining the Spirit Treasure Prototypes he excels at cannot be lower than thirty percent. Otherwise, Martial Uncle-Grandmaster would never conduct such a trade.
