Originally, these cultivation techniques might only have been cultivated to the Foundation Establishment Realm, or perhaps to the Golden Core Realm.
But with the cultivation of countless human cultivators, the collision of endless sparks of wisdom, combined with sudden enlightenment, these techniques can be evolved to the Mahayana Realm, and even the True Immortal Realm.
Moreover, they can also fill in many loopholes of the previous techniques.
It is precisely because of this that now the Xuanhuang Sect possesses not just one hundred and eight cultivation techniques that directly lead to True Immortality.
Generation after generation of deduction seems to have nurtured six hundred and sixty-six True Immortal level techniques.
If this evolution continues, even if thousands or tens of thousands of True Immortal techniques emerge in the future, it wouldn't be too big of a problem.
"No wonder the Book Worm has barely been able to evolve after reaching the Superior Eight Stages."
