In the brief time that Rui had spent here, he had already spotted patterns of traits in the behavioral psychology of those indoctrinated by the Virodhabhasa Faith. This allowed him to develop models that predicted not only whether someone was indoctrinated by the faith, but also allowed him to predict to what degree they were indoctrinated.
This was partially based on the same principles of the predictive model of the VOID algorithm, thus he was able to effortlessly execute it even though it had been the first time that he had done this.
Of course, the accuracy and precision left much to be desired, and it was not flawless. But it worked well enough.
Although he wasn't super confident about how effectively he would be able to read Martial Artists that had ascended to the Higher Realms, it appeared that at the very least, he could tell when a Martial Master wasn't the most devoted subject of a faith.
