They also place great importance on the Outer Domain Battlefield, specially setting up arrays such that if any powerful figure from outside arrives, they would sense it immediately.

The cries of shock from the disciples of the Four Emperors spread, causing the Wuji Sect to fall into a deathly silence, and terror was written all over everyone's faces.
