Lu Ye was not buying something from the Heaven's Mystery Vault for the first time, so he naturally knew how to quickly find what he needed.
A moment later, he stood within the Heaven's Mystery Vault, surrounded by shelves filled with Spiritual Artifacts, searching through them one by one.
There were many types of Spiritual Artifacts here, enough to meet any cultivator's needs.
As Second Senior Sister had said, Spiritual Artifacts used for artifact control differed from those used in direct combat. The former needed at least three restrictions: Spirit Storage, Foundation Strengthening, and Sharpness.
The Spirit Storage Restriction ensured an artifact's endurance. A cultivator's Spiritual Power was stored within this restriction and gradually consumed while controlling the artifact.
Without this restriction, one would end up like Lu Ye before, having to retrieve the Spiritual Artifact after controlling it for only a few breaths.
As for Foundation Strengthening and Sharpness, every Spiritual Artifact possessed them. The former reinforced the artifact itself and made it less likely to break, while the latter increased its lethality.
After making a round, Lu Ye found it difficult to choose. The Spiritual Artifacts here were generally more expensive than ordinary ones. Take his Crag Mountain Saber, for instance. With nine restrictions, it was considered the limit of a Low-Grade Spiritual Artifact, yet it had cost only one hundred and thirty-five Merit. But a Spiritual Artifact suitable for artifact control, if it had nine restrictions, actually cost nearly two hundred Merit.
By that measure, the Crag Mountain Saber he had bought back then had been quite cheap.
Just as he was about to buy one, he suddenly remembered that he did not need to purchase one from Heaven's Mystery Hall at all. Hua Ci should have plenty of Spiritual Artifacts.
