It wasn't just Chu Zheng who couldn't handle the rigors of mining; over ten martial masters also couldn't stand the daily remittance and chose to leave as well.
In fact, the conditions in the mine were considered extremely generous, and even by keeping only half, they earned much more than they would outside.
It was just a bit more arduous.
It was precisely for this reason that the majority of martial masters chose to stay.
Most of them were well into middle age or even in their sixties or seventies. They had given up their comfortable secular lives for the sake of struggle in this borderland between the Celestial and Mortal realms, not for themselves.
They had descendants. Even if they could not enter the Immortal Sect themselves, if any of their progeny had the natural Immortal Bone, the resources they had accumulated could be put to good use.
