This is a primary reason why the powerful who possess real strength like to follow wealthy forces. They don't have to worry about money. As long as the large forces bid for them, they can use those great resources.
Then, they can swear allegiance to the forces using martial arts, serving a number of years based on the value of those resources.
For instance, a strong cultivator at the half-step nascent soul stage would charge a yearly service fee of ten million spirit stones. So, if they're given one billion spirit stones, they must serve for a hundred years.
Such strong cultivators can live for at least a hundred thousand years, so what's a mere hundred years to them?
Moreover, cultivators like them don't need to go out often. They typically safeguard the large forces from within, intervening when necessary and cultivating when not. This is a pretty decent arrangement.
"Alright, I understand." Green Lady nodded.
