Another issue concerns the mindset of Cultivators themselves.
In the entrenched way of thinking among many Cultivators, mortals are frail and short-lived, sometimes a mere common cold or flu could snatch their lives away.
A Demon Beast could inadvertently let out a roar and it might scare several people to death.
With this way of thinking, they naturally don't believe that mortals could be of any help to Cultivators.
At best, they might allow mortals to do completely risk-free tasks like cooking and laundry.
This mindset isn't necessarily wrong, as if there were enough manpower, giving the same tasks to Cultivators would undoubtedly yield much better results than if mortals were to do them.
However, given the current number of Zhou Family Cultivators and clan members, they were far from the luxury of assigning several personal secretaries strictly for the Clan Leader's work, let alone two guards for the gates!
