There were thousands of grooves on the stone pillars for embedding the star Fern thorn soul essence.
In theory, there were many possible ways to embed the star Fern thorn soul essence in different grooves. This number would be very large, even infinitely large compared to the number of deductions a person could make in a limited time.
Even if Xia ruofei's spiritual power increased by a few times, it was impossible to turn his brain into a supercomputer. Even if it was a supercomputer, it could not complete such a huge amount of calculations in such a short time.
Hence, Xia ruofei had given up on using the exhaustive method to calculate the best combination.
He was using his own understanding of array Dao, the stone pillar array, and the array patterns. After combining these factors, he could actually eliminate most of the combinations.
On this basis, he substituted the star Fern soul essence for analysis, and the amount of calculation was naturally much less.
