Only when Liu Changxu began refining the Spirit Artifact Shield did he discover that it was nowhere near as simple as he had imagined.
After some practical attempts, he realized that his idea of refining a Spirit Artifact Shield from three spirit materials-second-tier gold-patterned iron, golden ironwood, and second-tier iron-armored rhinoceros hide-was deeply misguided.
Second-tier iron-armored rhinoceros hide, in particular, was unsuitable for refining a Spirit Artifact Shield. It was better used for making second-tier talismans or Spirit Armor.
After wasting two large pieces of second-tier iron-armored rhinoceros hide, Liu Changxu abandoned the idea of using it to refine a Spirit Artifact Shield.
To finish a Spirit Artifact Shield as soon as possible, Liu Changxu finally decided to set aside his plans for a composite shield for now. His artifact-refining skills were not yet sufficient to produce a Gold-and-Wood Dual-Attribute Spirit Artifact Shield.
Thus, Liu Changxu began refining a Spirit Artifact Shield from gold-patterned iron alone. Even so, the process remained extremely difficult.
Moreover, a Spirit Artifact Shield consumed an enormous amount of second-tier gold-patterned iron. The shield Liu Changxu was currently refining, for instance, required enough to make five Golden Rainbow Swords. The cost was simply too high, and Liu Changxu inwardly exclaimed, I can't afford this!
Aside from the enormous consumption of spirit materials, engraving the Spirit Artifact Shield's artifact runes was also extremely difficult.
To block all kinds of spell attacks, the Spirit Artifact Shield also needed to be engraved with miniature formations-namely, restrictions-each composed of at least a hundred artifact runes and capable of resisting spell attacks of various attributes.
Restrictions composed of different artifact runes served different purposes. Some fireproof restrictions excelled at resisting all kinds of flame damage, while others were adept at resisting physical damage. The higher the grade of a Magical Treasure,
