Several months had drifted by since Dan successfully implemented the fourth and most grueling Vitality Seal, the one governing the entirety of the brain and nervous system. During this interval, he witnessed tangible, vivid improvements in nearly every facet of his daily existence and his martial prowess. This advanced art had impacted him with profound depth—not merely refining his physical vessel, but accelerating his ongoing research, which grew more labyrinthine with each passing day.
Every internal pillar of his being was bolstered. Physical conditioning became swifter, more efficient, and less draining. Theoretical research grew deeper, clearer, and faster in its deductions. Practical experiments achieved surgical precision, with fewer errors and superior results. Everything had accelerated; everything had ascended.
One particular enhancement—perhaps the most intriguing to Dan personally—was his unique and uncanny ability to sense the spatial fabric surrounding him. This mysterious perception, which he had acquired years ago, allowed him to perceive the invisible lattice forming space itself—a web of interconnected lines and nodes that bound all things. Previously, he could only sense this network vaguely, leading him to defer its study.
Now, however, with the gargantuan leap in his neural processing and sensory perception, he could feel this spatial grid with startling clarity. It was detailed. It was precise. It was vivid.
With this newfound resolution, he began to contemplate practical methods to weaponize this perception. How could he transform this passive sensation into an active power? How could he manipulate the threads of the web rather than merely observing them? Could he birth entirely new techniques predicated on this understanding? The questions were exhilarating, promising a path of deep discovery.
As he immersed himself in the depths of this perception, he began to sense even finer, more profound details—nuances that had eluded him before. He discovered a staggering truth: this spatial network was inextricably and directly linked to time itself.
Duration, the temporal flow, the past, the present, and the future—they were not separate entities. They were not independent. They were intertwined, overlapping, and part of the same singular essence.
This discovery immediately triggered a connection to a profound scientific concept from his original world—the advanced Earth of his previous life. Sitting in his private laboratory, lost in thought, he retrieved the ancient data stored within his memory.
He recalled:
In Einstein's General Relativity—the revolutionary physical theory that reshaped humanity's understanding of the cosmos—time and space are never truly separate. They form a single, integrated, and interconnected fabric known scientifically as Space-Time. A single system of four dimensions merged into one: three spatial dimensions and one temporal dimension.
This realization carried a monumental implication: to control space—to manipulate the spatial fabric and the network—was, by definition, to manipulate time as well. A true alteration in one necessitated a change in the other. Distorting space affects the rate at which time flows; accelerating time alters the geometry of space. They are inseparable parts of the same equation.
Dan deduced with cold, direct clarity: if he truly wished to develop a potent and effective technique based on spatial manipulation, he had to understand time with equal depth. He had to account for it entirely in his design. He could not ignore the temporal aspect; he could not treat space in isolation. He had to master Space-Time as a unified system. This was the correct path—the true scientific methodology.
"The Second Hokage... truly a genius," he murmured softly to the empty room. He paused, his thoughts spinning faster. "How did he manage to develop a technique based on this principle in the future?"
He felt a clear sense of admiration—a deep respect for that particular mind. As someone who had watched the entirety of the Naruto anime in his original world before his transmigration, his initial favorite had been the First Hokage, Hashirama Senju. He had been drawn to Hashirama's naive, kind personality and his overwhelming strength as the founder of Konoha. Hashirama was inspiring, beloved, and heroic, possessing a childlike charm that made him impossible to hate despite his occasional simplicity.
But now?
After living in this harsh reality for long decades...
After immersing himself in the rigorous scientific, technical, and theoretical study of Ninjutsu, Fuinjutsu, and various phenomena...
Dan now held a clear and distinct preference for the Second Hokage, Tobirama Senju.
Tobirama was a technical genius without peer in the history of the Shinobi world. He had birthed dozens of revolutionary techniques from nothing:
The Flying Thunder Technique (Hiraishin)—a feat of instantaneous spatial and temporal manipulation!
The Reanimation Jutsu (Edo Tensei)—a technique that dared to manipulate souls and the cycle of life!
The Shadow Clone Jutsu (Kage Bunshin)—an incredibly practical and versatile tool!
Advanced sensory arts, powerful water-style techniques, and deep research into Fuinjutsu—all of it came from a single man. Dan viewed him now, with a deeper understanding of technical hurdles, as the Nikola Tesla or Albert Einstein of this world. A rare scientific prodigy. A true innovator. An exceptional mind. Such people were rare, and their value was beyond measure.
He made a firm resolution: in the future, when Tobirama Senju was born and officially appeared in this world, Dan would certainly seize the opportunity to meet him personally. Perhaps he would even guide him, mentoring the young genius to see just how far he could reach. The chance to direct such a mind was too precious to ignore—it would be a source of great amusement for Dan as well. He knew that Tobirama, while cautious and skeptical, respected strength, and Dan was certain he possessed more than enough power, intellect, and knowledge to earn that respect.
He shook his head slightly, returning to the present. "Leave that for the future. Not now."
He returned to his current planning for a technique rooted in space and time. Currently, he possessed a relatively clear theoretical framework for this art. He intended to begin practical experiments based on these theories very soon. It was the classic scientific approach.
It might take years. Perhaps decades. But the final result? It would undoubtedly be worth the labor. A technique based on the fabric of Space-Time itself. A power on an entirely different level.
A power that brushed against the fundamental laws of the universe.
