The tesseract, which Rizal now regarded as his guide in this strange world, emitted a faint blue light. The light moved, forming curved lines that pierced through the white space, as if carving a trail on a blank canvas.
"Follow." The voice echoed in Rizal's mind again. "This path... will lead you to her."
Despite the doubts still haunting him, Rizal felt he had no other choice. He had to trust the tesseract, to believe that this mysterious entity wanted to help him.
He stepped forward, following the winding trail of blue light. The white space around him shifted with each step. Invisible walls moved, perspectives rotated, and at times he felt like he was walking on the ceiling of his own world.
The farther he followed the trail, the stranger the things he saw became. Four-dimensional geometric shapes appeared and vanished, shadows moved in unpredictable patterns, and sometimes he caught glimpses of the three-dimensional world from impossible angles.
"What is happening to me?" Rizal murmured, more to himself than to the tesseract. "Am I... changing?"
He felt something different within himself. His perception seemed sharper, his thoughts clearer, and he felt as if the boundaries of reality were beginning to thin.
"You are adapting." The tesseract's voice was soothing. "This dimension... affects all who enter it. You are learning to see, feel, and think beyond the limits of the three-dimensional world."
Rizal recalled physics theories about brain plasticity, about how the human brain could adapt and change in response to new stimuli. Could his brain be forming new connections, altering its structure to process information from a higher dimension?
Suddenly, the trail of blue light stopped at a point. Rizal looked up and saw a sight that left him stunned.
In front of him, floating in the midst of the endless white space, was a very familiar object.
A pair of lab goggles.
Professor Indri's goggles.
