Just as Stein was about to see what will happen next, his head ached, as if he was being split in two. the perspective of Johann Schiller that he just acquired was slowly being torn away from him, but not to completely bring him back to the real world...
But to replace it with something else.
Stein felt like his sight is continuously fading in and refocusing, zooming out and zooming in. He never felt something more painful in his life. It felt like someone is continuously poking at his brain and reattaching every nerve, picking and prodding at it.
Johann Schiller's vision of the world is intermingling with something else. Something strange and completely opposite from the way he sees the world. The professor was full of hidden cynicism and yet still sees much potential if the world only worked the way he wanted. He was full of ambition.
