When she saw the devilry cultivators entering the back mountain of the Sect, her eyebrows raised slightly. There were arrays and boundary barriers within the Sect's boundary, how did the devilry cultivators enter the back mountain without anyone noticing?

She followed them closely and saw that the devilry cultivators had set up a boundary barrier there. When someone approached, the boundary barrier would send out a warning which allowed the devilry cultivators to escape as quickly as possible.
