After all, the aura in the Upper Bound was significantly more vibrant than the aura in the Lower Bound. It was beneficial for them to cultivate up above.
To return to the Upper Bound, they needed to travel through some peculiar place. It was okay for the three of them to do so, but not for Di Xuyue. She was too young and needed to be trained to level nine before she can be brought to the Upper Bound with her parents.
Of course, the Starry Crescent Land could not be without its Lord for long periods of time. So, they still had to come back once every six months until the next Lord was appointed. According to the heavenly law, Gu Xijiu needed to be the Lord for 10,000 years before the next Lord would appear.
However, when Di Xuyue had turned four, Di Fuyi noticed signs of a new Lord through examining the starry array. The odd thing about it was that the new Lord seemed to be currently outside of the Starry Crescent Land.
