By common social standards, it's inconceivable for a collective force, especially one that's a wealthy family with huge assets, to seek allegiance with a single person, particularly when the individual in question is merely a "youth fresh off the farm".
Yet, as Zhu Shi once told me, in Luo Mountain, in the world of demon hunters, an exceptionally powerful individual is in themselves an army, capable of being equivalent to a force even when operating solo. Therefore, the current situation is not so much a "wealthy family" seeking to follow a "youth fresh off the farm," but rather a "weaker force" wishing to integrate into a "stronger force," which makes much more sense.
