Sky Scar, controlling the body of the Demon King, emitted a faint aura of death, steering the spirit fluctuations of the shadow. Simultaneously, he used Soul Power to send a message to Luojia, warning her to keep a close watch on the castle's surroundings for the presence of possible accomplices.
Through his spiritual perception, Sky Scar had discerned the form of the shadowy figure. Just as he had thought, it was indeed a demon slightly smaller in size than the average human. It had penetrated their defences and was rapidly making its way towards his room. Judging from the energy it emanated, its strength was on par with a white-level demon which was not much different from his untransformed form. He should not underestimate it. An attempt to overpower it by force would not be effortless.
The door opened soundlessly, the shadow flashed in, and then the door closed again, as if nothing had happened at all.
