Chapter 146
Professor Caelum listened carefully as Nille finished speaking, his expression remaining calm, but his eyes narrowing slightly in thought.
Most students, as he had said, would have rushed to expand their spell lists the moment they accumulated enough gold or access to higher-tier techniques. In most academies, progression was measured by acquisition, more spells, higher tiers, rarer techniques. Power was often mistaken for accumulation.
But Nille's answer did not follow that pattern.
It followed something else entirely.
Caelum adjusted his stance slightly, as if organizing his thoughts before responding.
"That is unusual," he said at last, "but not incorrect."
He looked toward Nille directly now.
"Most students believe strength comes from having more tools. More spells. More options."
A faint pause followed.
"But what they often fail to realize is that unrefined tools create unrefined results."
His gaze shifted briefly toward the training chambers behind them.
"A Tier 3 or Tier 4 spell in the hands of someone who does not fully understand it becomes nothing more than wasted energy. Worse—it becomes predictable."
He turned back to Nille.
"Predictability is what gets most young awakeners killed."
Caelum's tone remained steady, almost instructional.
"What you are doing instead, refining Tier 1 techniques to their absolute limit—is closer to foundational mastery."
He gestured slightly with one hand.
"A well-compressed system of Tier 1 fire techniques, layered correctly, synchronized with timing and intent… can outperform a poorly understood Tier 4 spell in real combat conditions."
A brief silence followed as he studied Nille more closely.
"Especially in environments like the Twelve Sectors," he added. "Where instability and adaptation matter more than raw classification."
Then, more softly:
"So your reasoning is not ignorance."
"It is discipline."
He paused again, then offered a rare faint nod.
"But there is another layer to it."
His voice lowered slightly.
"You are not just avoiding higher-tier spells because they are unnecessary."
"You are avoiding them because something in you refuses to rely on what you have not fully made your own yet."
Caelum let that statement settle rather than press it further.
He finally concluded, almost neutrally:
"That is not a weakness, Nille."
"It is control and structure"
Professor Caelum turned slightly toward Lin Yue, his tone calm and instructional.
"Lin Yue," he said, "can you demonstrate your wind spell tier?"
Lin Yue nodded.
She raised her hand and formed a simple gesture.
A wind arrow condensed in front of her, thin, compressed, and spinning with controlled force.
She released it.
Fwoosh.
The arrow shot across the sub-basement.
It struck the far reinforced wall, scraping against it before dispersing without fully penetrating the surface.
Caelum observed the impact carefully.
"Hmm," he murmured. "That is a Tier 2 wind arrow under standard output."
He looked back at her.
"But you adjusted the compression and flow density before release."
Lin Yue gave a small nod.
"Yes."
Caelum's eyes narrowed slightly in understanding.
"That means your base technique is higher than what you are currently outputting."
He folded his arms.
"What is your maximum casting limit?"
Lin Yue hesitated only briefly before answering.
"I can cast up to Tier 7."
A faint shift passed through the air.
Even Caelum paused at that.
"But…" Lin Yue continued honestly, "I can only sustain five shots at that level before my spiritual core destabilizes."
She glanced toward Nille.
"That's why he was right to suggest the crossbow system. My Tier 7 arrows are powerful, but they are not practical if the target is fast or constantly moving."
Nille looked at her, then asked quietly, "This is because of the scroll from the underground chamber?"
Lin Yue nodded.
"The one connected to the mine vein beneath the swamp castle."
Caelum exhaled slowly, as if confirming something he already suspected.
"That explains it."
He began walking slowly as he spoke, letting the explanation form naturally.
"High-tier spell access is not the same as high-tier spell usability."
He glanced toward the engineers working in the background.
"Most spell stores sell techniques up to Tier 5 for a reason. Beyond that threshold, the strain on the spiritual core increases exponentially, not linearly."
He raised a hand slightly, as if illustrating invisible layers.
"A Tier 1 spell might consume a small fraction of your energy. A Tier 2 slightly more. But by the time you reach Tier 6 or 7, the output no longer scales gently."
"It spikes."
He looked at Lin Yue directly.
"In your case, your core is stable, which is good. But stability does not mean unlimited capacity."
He tapped lightly at his own chest.
"Think of the spiritual core like a reservoir."
"It can hold a certain volume of energy safely. Beyond that, you can still force more power through it—but the structure begins to strain."
Lin Yue listened carefully.
Caelum continued.
"You said you can store up to Tier 5 safely."
"That is your sustainable limit."
He paused.
"But you can temporarily push to Tier 7."
"That means you are not expanding your reservoir, you are overpressurizing it."
Lin Yue nodded slowly, understanding forming in her expression.
Caelum then turned slightly toward Nille.
"And in your case…"
His eyes narrowed in assessment.
"Your structure is different."
Nille said nothing.
Caelum continued anyway.
"I can detect at least a Level 25 baseline capacity in your spiritual framework."
A few nearby workers paused briefly but did not interrupt.
Caelum's tone remained professional.
"That translates roughly to a spiritual energy storage of around 2,500 units."
He gestured slightly toward Nille's presence.
"Which explains why your techniques feel controlled rather than strained. You are not pushing your limits constantly, you are operating well within them."
He allowed a brief pause.
"Most students never reach that level of internal stability."
Then he looked between both of them.
"In simple terms: Lin Yue has access to high power but limited endurance at that tier."
"Nille has lower peak burst techniques at the moment, but far greater control and capacity to sustain growth without collapse."
He concluded calmly:
"One relies on controlled bursts."
"The other relies on structural endurance."
"And in real combat… both are valuable, but only when they understand their own limits clearly."
Professor Caelum Verdanis Eruien raised a hand calmly.
The surrounding sub-basement faded from view.
Sound dissolved first.
Then light.
Then distance itself seemed to fold inward.
In an instant, Nille and Lin Yue found themselves inside Caelum's personal space domain.
It was not a chaotic void.
It was structured.
A vast, pale expanse like an open lecture hall suspended in white mist. Floating rune panels drifted in slow motion, each one displaying shifting diagrams of elemental flow, spell trajectories, and energy compression models.
This was not just a combat space.
It was a teaching domain.
Caelum stood at the center, his voice echoing gently without distortion.
"Here," he said, "we can speak without interference."
He turned slightly toward Nille.
"I want to expand on your idea of stacking Tier 1 fire bursts."
A small flame appeared in his palm.
Stable.
Controlled.
"Your current method," he explained, "is compression stacking—multiple Tier 1 bursts layered like a shotgun shell."
He demonstrated.
The flame split into several smaller bursts, then compressed together into a denser core before being released forward in a short explosive wave.
A sharp pulse of heat spread outward.
"It works," Caelum continued. "It increases immediate impact by forcing multiple low-tier outputs into a single discharge window."
He let the flame dissolve.
"But it has limits."
Nille watched carefully.
Lin Yue stood slightly behind him, also focused.
Caelum raised one finger.
"The problem is synchronization."
"When stacked spells are not perfectly aligned, they create micro-disruptions in flow timing."
He gestured, and the floating rune panels displayed overlapping energy waves colliding imperfectly.
"When that happens, energy is wasted internally rather than projected outward."
He paused.
"Which is why there is a more refined approach."
The rune panels shifted.
Now showing a single continuous spiral.
Not stacked bursts.
Not layered outputs.
But a flowing, rotating circuit.
Caelum's voice became more precise.
"Instead of stacking separate fire bursts…"
"You convert Tier 1 fire into a continuous circulation loop."
He pointed at the diagram.
"Think of it like a closed combustion engine rather than individual detonations."
The visual showed fire energy being drawn back into a central loop, continuously compressed and re-released through the same channel.
"This method is called Internal Flame Cycling."
"The spell does not end after casting."
"It continues to feed on itself through controlled return flow."
Lin Yue blinked slightly.
"So instead of multiple arrows… it becomes one sustained system?"
"Correct," Caelum said.
Nille's eyes narrowed slightly as he processed it.
Caelum continued.
"The advantage is efficiency."
"You are no longer wasting energy resetting the spell after each burst."
"The flame remains active in a controlled loop, allowing you to release repeated micro-explosions with almost no external re-casting."
He raised his hand again.
The flame reappeared, but now it rotated slowly in a ring rather than flickering outward.
"With training, you can release it in three forms."
He demonstrated:
First: a thin sustained beam of compressed fire.
Second: rapid pulse detonations like controlled machine bursts.
Third: a delayed ignition wave that detonates after travel—useful against fast airborne targets."
He looked at Nille directly.
"This third form is particularly relevant to your current expedition."
Nille understood immediately.
Stymphalian Birds.
Fast.
Unpredictable.
Aerial attackers.
Caelum's tone remained steady.
"This method also solves your earlier limitation."
"You do not need higher-tier spells immediately."
"You refine Tier 1 until it behaves like Tier 3 or 4 output in efficiency."
He lowered his hand.
The flame vanished.
"But it requires discipline."
"Not power."
"Control of timing, breath, and intention down to milliseconds."
Lin Yue looked impressed but also cautious.
"And the risk?" she asked.
Caelum answered honestly.
"Spiritual feedback if the cycle destabilizes."
"But compared to Tier 7 overcasting…"
"It is significantly safer for long-term use."
He turned slightly back toward Nille.
"In simple terms: your shotgun stacking method is explosive."
"This method is continuous control."
"One wins by impact."
"The other wins by endurance and precision."
He paused briefly.
"And for someone like you…"
His eyes narrowed slightly, thoughtful rather than critical.
"It aligns better with your existing combat philosophy."
Nille didn't respond immediately.
He was already mentally mapping the system.
Not as theory.
But as structure.
Caelum allowed the silence.
Then added one final thought.
"If your earlier approach was learning how to strike harder…"
"This is learning how to never stop striking at all."
Nille didn't respond immediately.
He simply raised his hand.
A small Tier 1 fire spell formed at his fingertips—simple, familiar, almost routine.
But this time, he didn't release it.
Instead, he focused.
Not on output.
Not on power.
On flow.
On continuity.
On the idea Professor Caelum had just shown him—fire that did not end, but cycled.
He exhaled slowly.
Then activated the spell.
Fwoom.
The fire burst formed—but instead of detonating outward and fading, it rotated inward.
A tight loop of flame stabilized in front of him, like a compressed ring of burning light.
It did not scatter.
It did not collapse.
It spun.
Controlled.
Sustained.
Nille's eyes narrowed slightly.
He adjusted his spiritual rhythm.
A second pulse entered the loop.
Instead of creating a new burst, it fed into the existing structure.
The flame thickened slightly—then stabilized again.
Professor Caelum observed silently.
"Good," he said calmly. "You're maintaining coherence."
Nille focused harder.
A third internal pulse was added.
The flame responded immediately.
Instead of exploding outward like a shotgun stack, it compressed into a denser internal cycle.
Then—
POP—POP—POP.
Small controlled detonations began to appear inside the flame ring itself.
Not external blasts.
Internal micro-bursts.
Each one pushed pressure outward in short, precise waves without breaking the structure.
Lin Yue's eyes widened slightly.
"It's not collapsing…" she murmured.
Caelum nodded once.
"Because he's maintaining the return flow."
Nille adjusted again.
This time, he guided the flame forward.
The rotating fire ring moved through the air like a controlled projectile.
A floating, spinning engine of compressed heat.
Then he focused on a distant rune target panel.
He triggered a delayed release.
THUM.
The fire ring suddenly released all stored pulses at once.
Not as a chaotic explosion—
But as a perfectly timed chain detonation.
BOOM—BOOM—BOOM—BOOM.
Each burst hit the same point in rapid succession.
The target panel shimmered violently under the sustained pressure, then cracked under the final impact wave.
The rune shield flickered red.
Then stabilized.
Silence followed.
Nille slowly lowered his hand.
The flame dissipated cleanly.
No backlash.
No instability.
Only controlled energy decay.
He blinked once.
"…It works," he said quietly.
Professor Caelum allowed a faint nod.
"Yes."
He stepped forward slightly.
"But more importantly…"
His eyes sharpened with approval.
"You didn't just copy it."
"You adapted it to your own rhythm on the first attempt."
Lin Yue looked between them, then at Nille.
"That was… fast," she admitted.
Caelum's tone remained calm.
"For most students, this technique takes weeks to stabilize."
He glanced at Nille.
"For him, it took understanding."
A brief pause.
Then Caelum added something quieter.
"This is what happens when someone stops forcing power…"
"And starts shaping it instead."
The training space remained still for a moment longer, as the floating rune panels slowly recorded and analyzed the result.
And for the first time in that space, Nille wasn't just using fire.
He was learning how to let it breathe.
Professor Caelum lowered his hand slightly after observing their results.
His gaze moved between Nille and Lin Yue, as if weighing their understanding more than their raw performance.
"You can see the difference in usage and consumption," he said calmly. "It's lower now. Much lower."
A faint rune projection appeared beside him, displaying comparative readings—spiritual output, energy loss, and recovery rate.
"With this structure," he continued, "you can cast this type of attack spell at least twice the previous number before fatigue sets in."
He paused briefly, then added the limitation without softening it.
"But the issue now is casting time."
He turned slightly, facing both of them more directly.
"Efficiency is useless if your reaction speed cannot match the battlefield."
Lin Yue nodded slowly, still processing the internal cycling concept she had just used.
Nille said nothing, but his attention sharpened.
Professor Caelum raised his hand again.
"This is what I mean."
A small wind arrow formed instantly at his fingertips.
No hesitation.
No visible buildup delay.
Just formation.
Compression.
Release.
SHHK.
The wind arrow shot forward and struck the far rune target in a clean, precise line.
But what stood out wasn't the impact.
It was the speed.
Almost no casting gap existed between intention and execution.
Lin Yue blinked once.
"…That was instant," she said.
Caelum nodded.
"Yes."
He raised his hand again.
Another wind arrow formed immediately.
Then another.
Then another.
Each one appearing in near-perfect succession, spaced only by fractions of a breath.
SHHK—SHHK—SHHK.
All struck different points on the target wall with controlled spacing, like a practiced sequence rather than individual casts.
He lowered his hand again.
"This is what training reduces," he explained. "The delay between thought and formation."
He looked at Nille.
"Your current method is structurally correct, but still deliberate. You are building the spell every time."
His tone remained neutral, not critical.
"That is why your casting speed lags behind higher-tier casters."
Lin Yue glanced at Nille, then back to Caelum.
"How do we shorten it?" she asked.
Caelum answered simply.
"Repetition until the structure becomes instinct."
Then he added a second point.
"And compression of decision steps."
He pointed lightly toward the rune diagram floating beside them.
"Right now, you think: form → stabilize → reinforce → release."
"That is four steps."
He tapped once.
"This must become one."
A brief pause.
Then his voice softened slightly.
"But understand this clearly, speed does not replace structure."
"If your foundation is unstable, faster casting only means faster failure."
He let the point settle.
Then looked between them again.
"You are both already ahead of most students in understanding."
"But the next stage is not learning more spells."
"It is learning how to become the spell itself."
The training space fell quiet again, only the faint hum of rune systems continuing their silent calculations around them.
Professor Caelum let the domain dissolve slowly.
The white space folded back into itself like mist being drawn into a closed window.
Sound returned first—the distant hum of Rune Forge machinery.
Then light.
Then the weight of the physical world.
He sat back down on the bench as if nothing significant had happened at all.
For a moment, he simply expected them to rest.
To process.
To reflect.
Instead—
Nille and Lin Yue exchanged a brief glance, gave a quiet nod, and walked away.
Straight toward the secured elevator.
Professor Caelum blinked once.
Then exhaled a small, amused breath.
"…They really don't rest like normal students," he muttered.
He leaned back slightly, watching them disappear.
A few seconds later, Nhulla Loresong arrived holding the enchanted gas mask system, pausing when she noticed the empty space.
She tilted her head.
"Where are those two going?"
Caelum didn't even turn fully.
"Up," he said simply.
Nhulla paused, then adjusted her grip on the mask case.
"…Should I be concerned?"
Caelum finally smiled faintly.
"Not yet."
He leaned back further.
"Just give them a few minutes. Better to wait until they finish whatever they've decided is necessary."
Meanwhile, the elevator rose steadily.
The rune-lined chamber vibrated softly as it carried Nille and Lin Yue upward toward the main testing floors.
Neither of them spoke much.
Not because there was nothing to say—
But because the training idea had already formed between them.
By the time the doors opened, their decision was already made.
The training hall above the sub-basement was wide, structured like a controlled combat arena. Rune barriers lined the walls, and multiple observation arrays floated near the ceiling. It was one of six official testing halls used by Rune Forge clients and academy personnel.
The guards checked their access once.
Then twice.
And then stepped aside without question.
Whether due to clearance, reputation, or unseen influence, they did not block the way.
Inside, the hall was empty.
Perfect.
Controlled.
Ideal.
Nille stepped in first.
He scanned the space quickly.
Then nodded once.
"Three training golems," he said.
Lin Yue understood immediately.
Not random sparring.
Not single-target testing.
Coordination training.
Adaptation under pressure.
They activated the system.
Three sparring golems rose from recessed platforms along the floor—each one calibrated differently.
One focused on speed and aerial movement.
One on reinforced defense and counterstrike patterns.
One on unpredictable multi-angle aggression.
The runes lit up.
The training began.
The first engagement came instantly.
The speed-type golem launched forward, closing distance in a blur of motion.
Lin Yue reacted first.
A wind arrow formed—but this time, she did not hesitate.
She compressed it mid-cast, applying the internal cycling structure they had just learned.
But instead of firing directly—
She angled it.
"Disrupt its path," she said.
SHHK.
The wind arrow didn't just fly forward—it curved, creating a rotating pressure field that forced the golem's movement slightly off-line.
Nille moved at the same time.
He stepped in with a low martial stance—his body shifting like a coiled spring.
A Tier 1 fire burst formed at his palm, but instead of releasing outward, he compressed it into a tight internal cycle.
Then—
He struck.
Not with the spell alone.
But with the motion of his body.
A short palm strike.
BOOM.
The compressed fire burst detonated at the exact moment of impact, launching a controlled shockwave into the golem's torso.
The golem staggered.
Not destroyed.
But destabilized.
The second golem entered.
Heavily armored.
Slower.
But built for punishment.
It raised its arm and slammed downward.
Lin Yue adjusted instantly.
"Hold it for half a second," she said.
She formed a wind cycle again—but this time sustained it longer.
The rotating pressure field expanded into a spiral barrier.
Not blocking forcefully—
But redirecting it.
The golem's strike slid off-angle, dragged by the rotating airflow.
Nille used the opening.
He stepped forward again—this time combining footwork with rhythm.
A controlled martial sequence.
Two steps in.
One pivot.
A shoulder rotation.
Then another compressed fire burst—released not at full strength, but as a chained micro-detonation.
THUM—THUM—THUM.
Three controlled impacts landed in sequence along the golem's joint structure.
Its arm buckled slightly.
The third golem activated.
Fast.
Erratic.
Unpredictable.
It moved like it was intentionally breaking patterns.
Lin Yue frowned slightly.
"This one is adjusting mid-fight."
Nille nodded once.
"Then we reduce decision time."
He didn't cast immediately.
Instead, he moved.
His body shifted into a more refined arc, less brute martial technique, more adaptive flow.
He read movement instead of reacting to it.
Then—
He cast mid-motion.
Fire cycle activation.
Instant compression.
Release timing shortened.
SHHK—BOOM.
A burst detonated just ahead of the golem's path, forcing it to adjust.
Lin Yue followed immediately.
Her wind arrow formed almost simultaneously now—faster than before.
No hesitation window.
No visible delay.
Just formation → reinforcement → release.
SHHK!
The arrow struck the golem's flank and destabilized its trajectory mid-dash.
Nille closed in.
One final movement.
A short martial step.
Palm raised.
Fire cycle fully stabilized.
Then a precise strike.
BOOM.
The golem froze.
Its systems flickered.
Then shut down.
Silence returned to the training hall.
Only faint rune glow remained.
Nille lowered his hand slowly.
Lin Yue exhaled, steadying her breathing.
A moment passed.
Then another.
Nille spoke quietly.
"…It went from one minute."
Lin Yue finished the thought.
"To a few seconds."
They looked at each other briefly.
Not surprised.
Not overwhelmed.
Just aware.
They had crossed a threshold.
Above them, the observation runes recorded everything in silence.
And far below, Professor Caelum remained seated on the bench, perfectly still, as if the world above him had already followed a path he had quietly predicted.
His gaze lingered on nothing in particular—yet it felt like he was observing everything at once.
A faint smile formed at the corner of his lips.
Not surprise.
Not approval.
Recognition.
Nhulla Loresong, standing nearby with the enchanted gas mask still in hand, tilted her head slightly as she noticed his expression.
"They went straight back to training," she said.
Caelum gave a small nod.
"Yes."
A pause.
Nhulla glanced upward, as if she could somehow see through the floors into the testing halls above.
"…At this rate, they'll break the schedule again."
Caelum exhaled softly, almost amused.
"They already have," he replied.
He leaned back slightly, fingers interlacing.
"But not in the way most people think."
Nhulla waited.
Caelum continued, voice calm and measured.
"Most students treat improvement as accumulation. More spells. More techniques. More tiers."
He looked upward now, gaze distant.
"But those two… they treat it as refinement."
A faint glow from the rune systems flickered across his face.
"They are compressing experience itself."
Nhulla frowned slightly. "That sounds dangerous."
"It is," Caelum admitted without hesitation.
Then, after a brief pause:
"…But it is also efficient."
Silence settled between them again.
Above, faint vibrations from the training hall echoed through the structure—subtle impacts, controlled bursts, rapid shifts in movement. Not chaotic. Not reckless.
Disciplined acceleration.
Caelum closed his eyes for a moment, as if mentally tracing their progress.
"When I first saw him," he said quietly, "Nille looked like someone trying to outrun something that wasn't following him anymore."
Nhulla listened without interrupting.
"But now," Caelum continued, "he's no longer running."
A pause.
"He's learning how to move forward without breaking himself."
He opened his eyes again.
"And the girl beside him… she doesn't slow him down."
His tone softened slightly.
"She stabilizes his direction."
Nhulla gave a small hum of acknowledgment, still watching the ceiling.
"So what now?" she asked.
Caelum's faint smile returned.
"Now?" he said.
He stood slowly, finally shifting from his seated posture.
"Now we wait for them to realize they've already outgrown the hall they're standing in."
He turned slightly toward the corridor.
"And when they do…"
A brief pause.
"They'll stop asking if they can improve."
His eyes narrowed gently, thoughtful.
"And start asking how far this can actually go."
