The Extra is a Genius!?-Chapter 560: Spatial Transition Theory

Noel leaned forward, elbows resting on his knee, the journal open between his hands. The title at the top of the page stood firm and clear.

Spatial Transition Theory.

The handwriting had changed. Sharper. Steadier. Like steel after heat.

This was not the Nicolas who had just arrived at Adept. This was someone who had already built something with his own understanding.

Noel began reading slowly.

Nicolas wrote that most mages misunderstood teleportation from the start. They treated it like speed taken to an extreme, or like folding a map and stepping across it. According to him, that way of thinking guaranteed instability.

Teleportation was not movement.

It was positional replacement.

He described space as structured rather than empty. Every location carried a fixed arrangement, a quiet geometry that existed whether someone noticed it or not. Distance between two places was secondary. What mattered was alignment.

Noel’s eyes narrowed slightly.

Nicolas explained that a mage could not shift to a place they had never stood in. The body recorded spatial anchors the way muscle remembered motion. Even if the mind blurred details, the imprint remained. To transition correctly, five elements had to match: three-dimensional orientation, altitude, ambient mana flow, gravitational direction, and environmental pressure. If one failed, the shift fractured.

Noel read that part twice.

’So it’s not about jumping across space,’ he thought, his mind moving steadily, ’it’s about becoming the coordinates you want to occupy.’

He closed his eyes for a moment.

The chamber had weight, not elemental but structural, like a cube enclosing him. The walls pressed outward in fixed angles. The floor pulled downward with steady certainty. The air felt dense but calm.

He reached outward with memory toward the corridor beyond the door. He had walked it hundreds of times. The slope near the corner. The slight draft near the stairs. The ceiling lower by a fraction compared to the training chamber.

At first, it was only recollection.

Then something else surfaced.

A faint sense of alignment, like tracing invisible lines in the dark.

Noir’s presence brushed his thoughts.

’You feel it?’

’Something,’ Noel replied internally, not opening his eyes yet. ’It’s like the world has edges you normally ignore.’

He returned to the text.

Nicolas compared this theory to shadow-based movement. Shadow Step relied on darkness as a bridge. It slipped through an existing medium. Spatial Transition required none. It did not pass through. It recalculated within the same structure.

Noel did not hesitate for long after finishing the theory. He closed the journal carefully and placed it beside him, though his fingers remained resting on the leather cover for a moment, as if grounding himself in what he had just read. Spatial Transition was not something that rewarded doubt.

’I’ll try it,’ he murmured inwardly.

Noir lifted her head at once. Her purple eyes sharpened with interest, faint streaks of violet along her black fur catching the low light of the chamber as she rose to her paws. She did not move closer yet, but her attention fixed entirely on him.

Noel stood slowly and let his breathing settle. This time he did not focus on mana circulation or elemental flow. Instead, he focused on structure. The chamber around him felt different now that he was paying attention. Not simply a space filled with air and stone, but a fixed geometric container holding him in place.

He chose the corridor beyond the reinforced door. He had walked it countless times, enough for his body to remember the exact slope near the turn, the slight change in air density near the staircase, the subtle echo that followed footsteps there.

He did not measure the distance.

He aligned the reference.

Height relative to ground. Gravitational direction. Ambient mana flow outside the reinforced walls. Pressure density. He adjusted each internal parameter the way he would adjust a formation array, careful and precise, until the memory of the corridor felt less like recollection and more like positioning.

’This isn’t about crossing space,’ he thought calmly. ’It’s about matching it.’

He activated the spell.

There was no sensation of falling into shadow. No tunnel forming around him. The chamber did not distort or ripple.

It simply ceased to be where he was.

The corridor enclosed him instead.

For a brief second his shoulder brushed the stone wall, slightly misaligned, off by a few centimeters, but the transition held. His body stabilized immediately.

The mana drain was noticeable, heavier than Shadow Step, yet stable, like sustaining a controlled formation rather than forcing a rupture.

Noel exhaled slowly and recalibrated before returning to the chamber with the same methodical precision. The shift back felt just as clean.

He turned toward Noir.

’Come here,’ he said within their shared thoughts.

She stepped closer without hesitation.

This time he anchored both of them within the spatial frame. Two masses, one coordinate set. He refined the alignment more carefully, compensating for her weight and position beside him, ensuring gravitational orientation remained synchronized.

When he activated the spell again, the corridor replaced the chamber without resistance.

The mana consumption increased, but not drastically. It stretched rather than doubled, distributing the spatial load instead of replicating it.

Noir shook herself lightly once they reappeared inside the chamber, violet streaks along her fur catching faint residual mana.

’It feels different from Shadow Step,’ she observed, her tone thoughtful rather than excited. ’There’s no sense of slipping through anything. It’s as if the world adjusted and placed us elsewhere.’

Noel nodded, studying the residual flow in his core.

’Shadow Step uses shadow as a bridge. This doesn’t. It rewrites our position directly within the structure. That makes it slower to calculate, but far more stable.’

He considered the implications carefully.

’In direct combat, Shadow Step remains faster for short bursts. But for repositioning allies, retreating, or controlling larger movements, this is superior. And more efficient when transporting multiple bodies.’

His gaze drifted briefly toward the journal.

Spatial Transition was not flashy. It demanded precision and awareness.

And that made it extremely dangerous.

Noel picked the journal up again and turned several pages until a new section caught his attention. The title was concise but dense in meaning.

Gravitational Axis Theory.

He read more slowly this time.

Nicolas did not describe gravity as weight. He described it as orientation. As the dominant direction that space imposed on matter. According to him, increasing gravity was not simply pressing harder downward. It was reinforcing the vertical axis. Redirecting it was not pushing sideways, but redefining which direction space considered "down."

Noel’s brows drew together slightly as he continued.

The theory was elegant on paper. Manipulating the gravitational vector allowed a mage to anchor an opponent, destabilize footing, lighten movement, or create localized points of attraction. It sounded clean in theory, structured like the spatial model he had just practiced.

But when Noel tried to apply it, the difference became clear.

He stood upright and attempted the simplest adjustment: reducing the gravitational pull on his own body. He focused on redefining his vertical axis rather than decreasing weight directly.

For a second nothing happened.

Then the shift came too abruptly.

His balance wavered and he had to step forward to steady himself. The sensation was disorienting, as if the floor had tilted invisibly beneath him.

He corrected quickly, narrowing the adjustment and trying again with smaller increments. This time his body lightened slightly, not enough to lift him, but enough to reduce the pressure in his legs.

He increased it again.

The weight returned heavier than expected, pressing down unevenly. He released the spell before it destabilized him further.

Noir watched, purple eyes attentive.

’This one isn’t as smooth,’ she observed.

Noel let out a short breath that almost turned into a dry laugh.

’No... it’s not,’ he admitted, rubbing the back of his neck. ’Honestly, I don’t fully get what I’m doing wrong.’

He looked down at the floor, replaying the shift in his head.

’I understand the theory. Axis. Direction. Dominant pull. It makes sense when I read it.’ He frowned slightly. ’But when I try to apply it, it just feels... off. Like I’m pushing in the wrong place without knowing where that place even is.’

He tried again, this time attempting a smaller adjustment, but the gravitational field wavered unevenly and he canceled it before it destabilized further.

He clicked his tongue softly.

’Yeah. No. Something’s missing.’

Noir tilted her head slightly, watching him with quiet interest.

’You don’t like not understanding it.’

’Obviously,’ Noel replied, though there was no irritation in his tone. Just honesty. ’Teleportation felt logical. Structured. This... this feels like I’m guessing.’

He exhaled slowly, thinking.

Selene came to mind almost immediately.

Her control over gravity had always looked natural. Effortless. Like she wasn’t forcing it, just guiding it.

’Selene would probably see what I’m doing wrong in seconds,’ he muttered internally. ’She specializes in this. She understands it on instinct.’

He folded his arms loosely, gaze lowering again to the stone beneath his feet.

’I might need to ask her,’ he admitted. ’There’s no point pretending I can brute-force my way through something I don’t understand yet.’

Teleportation gave him movement.

Shadow gave him pressure.

Gravity... gravity would give him control.

But only if he learned it properly.
