Tianji Pavilion bore its name because of this Heavenly Mechanism Spirit Stabilizing Stone mineral vein. This was where the great power had risen: two rogue cultivator Immortal Kings had secretly discovered and occupied this vein, then gradually built up an enormous force step by step.
The mineral vein occupied by Tianji Pavilion could actually only be considered a small one. For the sake of sustainable development, Tianji Pavilion had mined it with extreme care. Its output was exceedingly scarce; after expending tremendous effort, only one stone would emerge every several hundred thousand or even a million years.
Fortunately, though their numbers were few, every Heavenly Mechanism Spirit Stabilizing Stone unearthed was guaranteed in quality. The lowest grade was Three-Ring Dao Grade, while the highest reached Six-Ring Dao Grade. Of course, lower-grade Heavenly Mechanism Stones still made up the vast majority. Throughout Tianji Pavilion's records, Six-Ring Dao Grade Heavenly Mechanism Spirit Stabilizing Stones had appeared only three times, yet they had laid a solid foundation for Tianji Pavilion.
Like many other mineral Dao materials, Heavenly Mechanism Spirit Stabilizing Stones had a wide range of uses. Yet the most common use for other Dao materials—for artifact refinement—was the most wasteful use for Heavenly Mechanism Spirit Stabilizing Stones.
When used for artifact refinement, Spirit Stabilizing Stones could only be considered decent. Their true and greatest uses lay in formations and puppets.
Using Spirit Stabilizing Stones to refine formation plates not only made the formations several degrees more powerful than conventional refinement, but also left the refiner clear-minded and sharp-eyed under the stones' influence. Their reactions would be enhanced for a short time, indirectly allowing formation refiners to absorb experience ahead of time during the refinement process.
That was precisely why Tianji Pavilion's people had achieved such great accomplishments in the Dao of formations.
