Shattered Innocence: Transmigrated Into a Novel as an Extra

Chapter 1091: What mana keeps

Every folio in Grand Lecture Hall A opened at once.

Pages rose from more than a hundred desks with the soft rustle of leaves disturbed by the same wind, then settled beneath the pale light of the mana-lamps as the hall surrendered itself to scratching quills and carefully measured breaths. Lucavion lowered his gaze toward the first page, read the title written across its upper edge, and felt whatever curiosity Selenne had cultivated in him over the last four hours suffer its first serious injury.

Quantitative Mana Analysis.

’What an ugly way to begin the morning.’

His eyes travelled farther down the page.

The first few problems contained enough unfamiliar notation to make him hesitate before he even reached the actual substance. There were named coefficients, abbreviated relationships between mana density and sustained output, and several symbols whose purpose Bruce’s education offered absolutely nothing useful for, because mathematics only helped when someone knew what the symbols represented in the first place. He could manipulate a relationship once he understood it; a century of Arcanian scholars assigning letters to principles he had never studied remained stubbornly outside that advantage.

That difference became apparent almost immediately.

During Tier I, he had often been able to stare at a formation until the strange notation fell away and the geometry beneath it began resembling something familiar. Here, the Academy assumed that the student already understood what each mark meant. A symbol could represent resistance, mana loss, structural tolerance, affinity interference, or something entirely different, and guessing the definition from the shape of the letter would have been an impressive new form of stupidity.

Lucavion rested the end of his quill against the page.

’So this is what education buys you.’

Convenient.

Annoying, but convenient.

He moved past the first problem after recognizing that half its information depended upon terminology he had never learned, then found slightly firmer ground in the next several questions. One concerned the distribution of mana reserves between several defensive positions, and although the Academy presented the scenario through formal ratios and standardized labels, Lucavion could eventually see soldiers hiding underneath the numbers. Another dealt with supply expenditure during repeated deployment, where the magical language changed the resources while leaving the underlying problem wonderfully ordinary: too little of something useful, too many people who wanted it, and consequences waiting for whoever distributed it badly.

His quill began moving more steadily.

The section remained uneven. Whenever the question gave him enough context to reconstruct what the quantities actually meant, Bruce’s mathematics and Lucavion’s battlefield instincts cooperated well enough. Whenever it expected familiarity with an academic convention, he slowed, searched for clues, and occasionally left a space empty when none appeared.

That irritated him less than it had during Tier I.

At least he understood the shape of his ignorance now.

The folio turned after he sealed the section, revealing a broader mixture of applied magical problems. Lucavion worked through several of them without much enthusiasm until one diagram caught his eye, mostly because something about it felt old before he had properly read the accompanying text.

A spear-shaped channel ran through the center of the depicted body.

Three routes branched from the core toward the shoulder, arm, and weapon hand, while a fourth returned through the lower meridian network. The question concerned instability produced when fire-aspected mana accumulated near the weapon-side shoulder during sustained reinforcement.

Lucavion stared at it.

His quill stopped.

Then his hand moved before his thoughts did.

He marked the second response.

Vent the excess through the weapon channel before returning the remaining flow toward the core.

The answer appeared on the page with such immediate certainty that Lucavion looked down at his own hand.

’...Huh.’

He knew this.

Not because Bruce understood magical fire circulation. Bruce had never possessed mana, nor had Earth prepared him for the maintenance of a cultivation core through a spear.

This belonged to Lucavion.

House Thorne specialized in fire cultivation and spear arts. Years ago, long before battlefields and Gerald and black stars, Lucavion had stood beneath the attention of instructors who expected the second son of House Thorne to learn the same foundations his siblings had learned.

The memory arrived softly enough to remain harmless.

A training spear resting across small palms.

Warm stone beneath bare feet.

A man’s finger tapping his shoulder.

”If the pressure gathers here, give it somewhere to go before you call it back.”

Lucavion blinked.

The lecture hall returned around him.

His fingers shifted around the quill, and for a brief moment he found himself almost amused.

’So I did learn something like this.’

There was no reason to argue with the memory.

He had stood there.

He had held that spear.

Somewhere inside the years he could no longer reach properly, an instructor had corrected his posture and made him repeat the same principle until it remained.

The certainty came more easily than the details.

That had become familiar in its own irritating way. His past rarely returned as a complete sequence. A sensation arrived first. A movement. A phrase. Sometimes the knowledge appeared without the memory that had taught it, leaving him certain that something belonged to him while unable to explain when he had learned it.

Lucavion finished the explanation as best he could. His terminology probably belonged to an older Lorian teaching tradition rather than modern Arcanian doctrine, and the examiner might dislike the phrasing, but the mechanism felt certain enough that he trusted it.

The next few problems passed more slowly.

Then one line changed everything.

Lucavion’s gaze stopped halfway through a paragraph.

Auxiliary sequence.

The words seemed ordinary.

Something beneath the recognition tightened.

His fingers curled around the quill until the narrow shaft pressed against the calluses along his hand, and a dull pressure gathered behind his temple before he had time to wonder why. He lowered his head slightly, allowing his hair to fall farther across his forehead while the sensation sharpened.

Ink.

A page.

The faint scrape of a quill moving too slowly.

Somewhere beyond the edge of sight, a voice spoke.

”Again.”

Lucavion’s breath caught.

For an instant, the Grand Lecture Hall became too bright.

A wooden desk surfaced through the glare.

He knew it.

That certainty came before the room surrounding it.

His hand was smaller. His wrist ached. Ink stained the side of one finger where he had dragged it carelessly across something already written, and another page waited beneath his hand, covered in diagrams whose meaning had apparently refused to enter his head quickly enough.

Frustration sat hot behind his eyes.

Not unfamiliar frustration.

His.

He had been here.

He had done this.

”Again, Lucavion.”

The pressure behind his temple pulsed.

The image broke.

Lucavion’s free hand rose beneath the desk and pressed two fingers against the side of his head.

’Again.’

The word itself was new.

The way it had reached him was not.

His hand remembering the shape of a quill before he understood why.

A familiar term escaping his mouth before conscious thought caught it.

Old knowledge surfacing through sensation, movement, and recognition while the memory surrounding it remained somewhere farther behind.

Lucavion closed his eyes for one measured breath.

The pain receded enough for him to read.

The question described a caster shifting attention from one portion of a spell while an auxiliary sequence preserved another function.

Lucavion understood the purpose.

More than that, he knew he had understood it before.

Once.

Properly.

The mechanism itself remained behind the wall.

His quill hovered.

Something almost followed the memory. An explanation concerning a command remaining active after the caster’s attention moved elsewhere. He could feel the shape of it close to the surface, but the moment he tried reaching after it, pressure returned beneath his temple.

Lucavion stopped.

’Fine.’

Forcing it had accomplished very little so far.

He wrote what remained available.

The auxiliary sequence kept part of the spell carrying out an established instruction while the caster’s attention moved elsewhere.

Anything beyond that became guesswork.

He left the formal portion unfinished and continued.

By the time the folio advanced again, the headache had faded into a thin irritation behind his temple, though his mood had changed with it. His earlier curiosity remained, but it had acquired teeth. Somewhere inside the original Lucavion existed knowledge that Bruce could touch only when the correct object, sensation, or word happened to strike the lock.

He disliked locked things.

Especially when they were inside his own head.

The next section opened beneath his hand.

Applied Spell Structure

Lucavion’s eyes moved down the page, passing several short references before one term caught them.

Mana Imprint.

His attention sharpened.

The definition beneath it remained mercifully brief. A mana imprint described a persistent tendency impressed upon mana through intention, allowing selected properties or responses to continue beyond the caster’s immediate conscious direction.

Lucavion read the sentence twice.

Then his mouth curved.

’So that’s what you call it.’

Selenne’s voice returned much more pleasantly than the earlier memory.

”You gave them conditions.”

Shape.

Position.

Density.

How far they could move.

Where they should return.

The three manifestations inside Chamber 3C had floated back into his thoughts before he even reached the actual problem.

This question, unlike most of the examination, was written out in full.

A sustained mana imprint preserves the intended shape and position of a manifestation with perfect accuracy under stable conditions. When ambient pressure begins changing, the caster strengthens the imprint to prevent deformation. Stability worsens with every correction.

Explain the error in the caster’s approach and describe how the imprint should be adjusted.

Lucavion stared at the question.

Then he almost laughed.

’This morning.’

Whoever had written this problem had apparently decided to be kind to him personally.

He leaned closer, and the answer formed through sensation before academic language had any chance to interfere.

The caster had made the imprint too rigid.

Lucavion remembered the spheres resisting the currents because he had tried to force them into exact positions. Every disturbance became a contest. Every correction created strain. The solution had only appeared once he allowed the manifestations room to move while preserving the conditions that actually mattered.

A boundary.

Rather than a prison.

His quill touched the page.

He wrote slowly at first.

The caster is treating preservation as immobility.

Lucavion paused, reading the sentence back.

That sounded acceptable.

He continued.

If the imprint forces the manifestation to preserve one exact state while the surrounding mana keeps changing, the structure must constantly fight conditions that could instead be absorbed. Strengthening the same instruction increases the conflict. The imprint should preserve a range rather than a single rigid result, allowing limited deformation while keeping a condition that guides the mana back toward the intended shape and position.

He stopped there.

The Academy probably possessed prettier words.

Adaptive tolerance.

Responsive imprinting.

Environmental compensation.

Some scholar had undoubtedly spent thirty pages deciding which one sounded most respectable.

Lucavion knew none of them.

Yet for once, the missing terminology felt almost irrelevant.

He could feel the answer.

He had bled for it four hours earlier.

What Lucavion could not see was the small cruelty hidden inside the question.

Students trained deeply in formal spell structure often saw the flawless imprint and assumed the structure required reinforcement. They trusted perfect geometry, perfect sequence, and perfect preservation because years of magical education taught them to build stability through precision. The question existed precisely to catch that instinct.

Sometimes the structure was correct while the relationship with the surrounding mana was wrong.

Sometimes feeling came before another line of theory.

Lucavion, who had spent most of his life on that side of the problem, had been handed the rare question that favored his ignorance almost as much as his talent.

He only knew that, for the first time since the examination began, the page in front of him felt familiar.

His quill moved again.

And this time, the words came easily.
