As the saying goes, when the upper beam is not straight, the lower beam is crooked.
The six saints each have different temperaments, so their disciples also vary in character.
For example, Laozi prides himself on his non-action; whether it's genuine or not, he has to maintain his persona.
Thus, as the Human Sect Master, even during ancient times when the Human Clan was nearly devoured entirely by the Demon Clan, he did not intervene.
His chief disciple, Master Monk Xuandu, follows his example and keeps a low profile on the Primordial Continent, seemingly uninvolved in major events.
Similarly, the two saints of the Buddhist Sect, Jieyin always speaks grandly, while Zhunti is extremely calculating and unscrupulous.
Therefore, most people in the Buddhist Sect talk grandly, but fundamentally, they are adept at scheming, even targeting their own people.
