8,000 mid-grade spiritual stones was right around the price of the non-damaged version of the Darksteel Flame Ruler.
As such, by making this trade, Lin Mo had effectively covered the cost of the original item, and it was also a great deal for him, since it was now broken.
[ Congratulations, host, for successfully auctioning a low-grade tier 9 Darksteel Flame Ruler ]
[ You have successfully triggered a 3000-fold rebate ]
[ Congratulations, host, for obtaining a high-grade tier 9 Prototype Darksteel Flame Ruler ]
There was a high chance of obtaining the complete form of an item from auctioning its incomplete form. As a result, Lin Mo now had the means to produce a complete Darksteel Flame Ruler using the prototype he had just obtained.
However, since Lin Mo had yet to learn any forging techniques, by the time he could forge his own weapons, he would likely have already acquired a spirit-grade one.
