The energy knot spun faster, resonating with Rizal's mind. He could sense urgency in the echoes of Professor Indri's thoughts, as if his mentor was trying to convey something crucial.
An idea sparked in Rizal's mind, bold and risky, inspired by his knowledge of quantum physics and his newfound intuition about the fourth dimension.
"If this dimension is an information network," he pondered, "then perhaps I can use knowledge to manipulate it."
He sifted through his memories, searching for relevant equations and theories. The Schrödinger equation, describing the quantum state of a system. The principle of superposition, stating that a particle can exist in multiple states simultaneously. And most importantly, the concept of quantum entanglement, where two particles, though separated by vast distances, influence each other.
Rizal focused his consciousness, attempting to 'see' the energy knot not as an object but as a collection of quantum information. He envisioned his mind as a particle entangled with Professor Indri's mind, and the energy knot as the medium connecting them.
With the caution of an architect redesigning the structure of a building, Rizal began to 'assemble' equations and theories in his mind, using them as 'commands' to manipulate the energy knot.
He honed in on the Schrödinger equation, trying to alter the 'state' of the energy knot, making it more stable and receptive. He applied the principle of superposition, imagining possibilities where Professor Indri existed both inside and outside the energy knot simultaneously. And finally, he concentrated all his energy on the concept of quantum entanglement, strengthening the bond between his mind and his mentor's.
As he 'constructed' these equations and theories, the energy knot reacted. Its spin accelerated, its light brightened, and Rizal could feel the echoes of Professor Indri's thoughts growing stronger.
And then, something extraordinary happened.
A rift opened in the midst of the energy knot, a glowing portal swirling with pure fourth-dimensional energy. And from within the portal emerged a figure familiar to Rizal.
Professor Indri, looking frail but conscious, smiled broadly in his direction.
"Rizal! You did it! You... you understand the language of this dimension!"
