The eerie white-clothed monster moved, slowly drifting towards Chen Ke.
The entire corridor also began to change gradually. The four sets of glass double doors and the surrounding walls melted away like a faded crayon drawing on a canvas.
The space returned to its original state, and Chen Ke realized he had been standing in an office all along. When he had first stepped out of the elevator, the corridor he was in was indeed real, but that shove had pushed him into an illusion.
The stone walls within the doorframe were nothing more than an illusion technique. It's just that the illusion was so lifelike, it had tricked his brain and made his body feel physical sensations.
Now, the white-clothed monster was standing by the glass door of the office, leisurely drifting towards him. Strangely enough, Chen Ke couldn't feel any killing aura from it.
