By the time the thirteenth Wind Element Spirit Stone had been used up, Xu Yi had finally refined his first Raging Wind Talisman. The wind pattern in the upper-right corner of the blue talisman was white, clearly marking it as a Level 1 Grade 2 wind talisman. Held in one's hand, it could carry its user a thousand miles.
After succeeding, Xu Yi did not immediately begin mass production. Instead, he carefully savored what he had learned from the process.
He knew very well that talisman refinement could never be guaranteed to succeed every time. Luck played an important role, too. All he could do was keep honing his technique and reducing mistakes, thereby improving his success rate.
After immersing himself in reflection for nearly an hour, Xu Yi began refining his second Raging Wind Talisman. Just as he had expected, his success rate with Raging Wind Talismans was nowhere near as high as it was with Swift Wind Talismans.
After three days, the remaining ninety-one Wind Element Spirit Stones had been used up, yet he had refined only eight Raging Wind Talismans—a success rate of less than one in ten.
Along the way, he had also refined a batch of Swift Wind Talismans to use in battle.
He had thought carefully about why his success rate with Raging Wind Talismans was so low.
Lack of practice was certainly a factor, but at its root, the reason was that Raging Wind Talismans required more wind-element spiritual power than Swift Wind Talismans.
One Wind Element Spirit Stone could often refine two or three Swift Wind Talismans, but it was barely enough to refine a single Raging Wind Talisman.
In terms of the finished talismans, Swift Wind Talismans were Level 1 Grade 1, while Raging Wind Talismans were Level 1 Grade 2.
