To forge a Spirit Treasure-grade natal flying sword, the main material alone was not enough. Something even more important was needed: spirit restrictions.
Spirit restrictions were restriction formations of Spirit Treasure grade, and they were indispensable.
Chen Lin possessed several spirit restrictions, primarily from the inheritances of the Xuanwu Shield and the Immortal Refining Gourd.
The Xuanwu Shield, in particular, employed a great many spirit restrictions.
However, most of the Xuanwu Shield's spirit restrictions were defensive and unsuitable for a flying sword built for killing. The Immortal Refining Gourd's treasure restrictions focused on storage and refinement, making them a poor match as well.
Thus, among the treasure restrictions he possessed, only those for changing size and remote control were currently usable. The others were not.
As for the ordinary treasure restrictions originally used to forge the Thunder Sword, their grade was too low to suffice for a Spirit Treasure.
After some thought, Chen Lin settled on a plan.
This was not actually difficult to resolve. Spirit restrictions were inheritances that could be copied. Precious as they were, they were not particularly rare; it simply depended on whether one was willing to pay enough in exchange.
If he were willing to offer the Myriad Souls Animating Technique, Artifact Refiners who possessed spirit restriction inheritances would flock to him, vying to make a trade.
Of course, he absolutely would not-and dared not-offer the Myriad Souls Animating Technique.
He had plenty of other things he could trade, however. If all else failed, he could offer the forging inheritance of the Immortal Refining Gourd. Exchanging it for some treasure restrictions should pose no problem.
The Immortal Refining Gourd's inheritance came from the old man in the Shanhai Realm and had no loose ends attached to it, making it ideal for a trade.
