Yue Xuexia had to face the reality that she is no longer an ordinary person but a cultivator. Compared to living in the mortal world for a hundred years, age, and then die, she and her family can no longer stay for too long in one place.
After all, they will not age and have to make sure that no one can recognize them a hundred years later or they would be considered monsters in this mortal realm.
This is also the reason why a cultivating clan like Hidden Tan Clan Sect lives in the mountain unknown to others. They don't age, and all of their clan members are cultivators. Just the fact that the country hides the existence of the cultivators makes it hard for the cultivators to live in this mortal realm.
Even so, Yue Xuexia didn't complain after all the other countries also hid the hidden strength of their own place. Why should Daxia expose the cultivators, who are also their trump cards?
