When he heard about the energy problem, he thought of a product he had created using Mechanical Techniques.
[Spirit Stone Battery]
This inspiration was obtained from the [Array Formation Stone].
By inscribing an array on a Low Grade Spirit Stone, even cultivators or innate masters who cannot use arrays can activate it, forming a simple one-time small array.
In the early days, Yang Shi always carried some [Array Formation Stones] with him and used them to kill a Qi Refining Stage Cultivator named Xiang Pichi.
And the principle of this item is... the Spirit Stone can provide the Spiritual Power needed for the array, continuously offering Spiritual Power once started, until the power of the Low Grade Spirit Stone is exhausted, and the simple little array dissipates.
