Ever since Zheng Wuji arrived, Patriarch Zhou had been making preparations.

He then began a more detailed scan.
There were the power fluctuations of one early-stage Core Formation Demon, as well as several others belonging to Foundation Establishment Demons.
With a Core Formation Demon present, the Foundation Establishment Demons were merely support.
