The mornings didn't feel foreign anymore.
Four ago, the courtyard had been unfamiliar ground. Now the stones held the imprint of their steps. Frost still formed before sunrise, but no one hesitated when stepping onto it.
Wu Feng did first impact of the day without warning.
The stone dipped under her heel and a low thud echoed across the yard.
Meng Hongchen glanced over from where she was coaxing frost along her fingers. "You're going to crack the foundation one of these days."
Wu Feng didn't look back. "If it cracks, it wasn't built well."
Ning Tian sighed softly. "Please don't test that theory on Shrek's property."
Wu Feng finally turned, faint smirk. "Relax. I'm controlling it."
"Rank thirty-five," Long Xiaoyi muttered as he adjusted his stance nearby. "You say that like it's small."
"It is," Wu Feng replied flatly. "Compared to them."
She tilted her chin toward Ji Juechen, who was cutting the air with almost insulting precision.
Ji Juechen didn't pause. "Rank fifty-five doesn't make you untouchable."
"It makes you annoying," Meng replied.
He stopped just long enough to look at her. "You're Rank fifty-seven."
"Exactly."
A thin plane of ice formed midair, sharper than before, denser. It didn't spread wildly. It obeyed.
Xiao Hongchen watched it for a moment before returning to the compact mechanism in his hands. "Your control improved."
Meng shrugged. "It's easier to condense now."
"Domain?" Wu Feng asked.
"Not fully. But I can feel it when I call for it."
Xiao Hongchen clicked the device shut and activated it. The core hummed smoothly.
"Rank fifty-six," he said casually. "And officially Rank Six engineer."
Ju Zi glanced at him from the side table where she was adjusting a translucent lens.
"You're saying that like you weren't already acting like one."
He smirked faintly. "Now I don't have to pretend."
Tang Ya entered mid-conversation, stretching her arms overhead.
"You're all insufferable in the morning."
"You're late," Ning Tian replied.
"I was working."
"With ink on your face?" Wu Feng asked.
Tang Ya wiped her cheek instinctively and scowled. "Shut up."
She walked into the center of the courtyard, flexed her fingers, and extended her Essence.
The ground responded.
Not explosively.
Controlled.
Two compact golems rose first—smaller than before but denser. A third formed behind them. Vines followed, weaving upward into an arching defensive structure.
Long Xiaoyi whistled softly. "That wasn't there last month."
Tang Ya tilted her head. "I had an idea."
"From the drawings?" Ning Tian asked.
Tang Ya nodded once. "He was bored. I wasn't."
Lin Huang, leaning against a pillar, didn't deny it.
Meng approached the structure and tapped one of the golems. It didn't crumble.
"You can hold three now?"
"For a while."
"And that gate?"
"Still slow to activate. Don't ask me to spam it."
Wu Feng folded her arms. "Rank forty-seven and already getting ambitious."
Tang Ya shot her a look. "You're thirty-five and acting like you're ancient."
"Thirty-five with a third ring."
"And still complaining."
Ma Xiaotao's presence shifted the temperature slightly before anyone noticed she had stepped forward.
Rank fifty-nine wasn't something she mentioned. It showed in the way her fire didn't flare unnecessarily. She stood still, eyes closed, heat drawn inward rather than released.
Zhang Lexuan watched from the side.
"You're going to do it here?" Lexuan asked calmly.
Ma Xiaotao opened one eye. "Why not?"
"Because if you miscalculate—"
"I won't."
Silence fell, not tense, just attentive.
Fire gathered.
Not wild.
Focused.
Ji Juechen stopped moving entirely.
Meng's frost thinned instinctively.
The compression wasn't dramatic. No pillar of flame shot upward. Instead, the heat folded into itself until the air tightened.
Then—
It settled.
Ma Xiaotao exhaled.
"That's it," she said simply.
Tang Ya blinked. "You just… did it?"
Ma Xiaotao nodded once. "Core's formed."
Wu Feng stared. "That's all?"
"What were you expecting?" Ma Xiaotao replied dryly. "Fireworks?"
Ning Tian stepped closer, sensing the internal shift. "It's… smoother."
"Good," Ma Xiaotao said. "I'm tired of fighting myself."
Zhang Lexuan gave a faint smile. "Rank fifty-nine suits you."
"Sixty will suit me better."
Across the courtyard, Long Xiaoyi stomped once and compressed the earth beneath his feet. The ground shrank subtly, propelling him forward in a burst of speed that hadn't existed months ago.
Meng raised an eyebrow. "You're cheating."
"I'm innovating," he shot back.
Su Mei clapped lightly, drawing everyone's attention.
"Hydrate before you drop," she said, already handing out prepared essence flasks. Rank fifty-six had made her frighteningly efficient. She was tracking everyone's output even while speaking.
Xiao Hongchen took one without argument. "You're scarier than Ji Juechen."
"I prefer reliable."
Lin Huang finally pushed away from the pillar.
"Switch," he said.
Red flared first—sharp, contained.
Blue followed—cool, fluid.
They didn't clash anymore.
Meng leaned slightly forward. "That's new."
"It's cleaner," Xiao Hongchen added.
Lin Huang didn't answer. He closed his eyes.
The presence beneath the surface responded.
Tushan Honghong didn't manifest as tails or avatar—just alignment. The first stage of integration wrapped around him like a quiet second heartbeat.
He moved.
The shift in pressure was subtle but undeniable.
Wu Feng watched carefully. "You're still hiding something."
"For now," he replied.
Ning Tian studied him for a moment longer than the others.
"You're integrating further."
"Just the beginning."
Tang Ya crossed her arms. "Everyone's beginning something lately."
"Four months will do that," Ji Juechen said.
No one argued.
The frost had melted.
And without anyone declaring it, the courtyard no longer felt like borrowed ground.
It felt earned.
No one contradicted Ji Juechen's comment.
Four months had brought familiarity.The fourth had brought something heavier.
Lin Huang stood where he was, eyes still closed, Red and Blue fading back into silence. The courtyard had returned to its normal weight, yet the impression lingered — like the echo of a step taken too firmly to forget.
Zi Ji tilted her head.
"That's it?" she asked, tail swaying lazily behind her. "You show a glimpse and then stop?"
Lin Huang opened his eyes. "I said I was hiding something. I didn't say I was done."
Wu Feng narrowed her eyes. "That's not reassuring."
Zi Ji laughed. "Good. Reassurance makes people sloppy."
She stepped forward, cracking her neck once, casually, as if stretching before a walk.
"You've been suppressing that fox for months," she continued. "I can smell it. Integration doesn't like being ignored."
Gu Yuena watched without interference.Bi Ji shifted her weight, already attentive.
Ning Tian felt it then — the pressure change, subtle but directional.
"Zi Ji," she said carefully. "This isn't—"
"A duel?" Zi Ji finished. "No."
She smiled, sharp and delighted.
"It's a test."
Before anyone could respond, Zi Ji moved.
No warning.No aura flaring.
Just raw, terrifying acceleration.
The ground cracked where she had stood, her fist already descending toward Lin Huang's chest, power compressed so tightly it bent the air.
Lin Huang reacted on instinct.
And for the first time—
He did not suppress.
The cerulean aura erupted outward, not as a burst, but as a transformation.
Blue light wrapped around his body like liquid glass, dense and alive, outlining muscle and bone. His Kitsune Essence surged violently before snapping into alignment, every channel widening at once.
Tushan Honghong answered.
Not as an image.Not as a voice.
As presence.
Lin Huang's pupils sharpened, the world slowing by a fraction as strength flooded his limbs. Not borrowed. Not forced. Simply… available.
Zi Ji's fist landed.
And Lin Huang caught it.
Not with technique — with his body.
The impact drove him backward, stone shattering beneath his heels as the cerulean aura rippled violently, dispersing the force across his frame. Pain flared, but it didn't cripple him.
Zi Ji's eyes widened.
Then she laughed.
"Oh, that's much better."
She pulled back and struck again.
This time, Lin Huang moved first.
He vanished from where he stood, reappearing half a step to the side, cerulean aura trailing like mist. His counterattack was simple — a straight punch, amplified by doubled strength and perfect coordination.
Zi Ji crossed her arms to block.
The shockwave cracked the courtyard tiles.
She slid back a full meter.
Silence fell.
Wu Feng's breath hitched. "He hit her."
"He survived," Meng whispered. "That's worse."
Zi Ji rolled her shoulders, grin widening. "So this is your first stage."
Lin Huang exhaled sharply, cerulean light pulsing brighter. "Incomplete."
"Good," she said. "Then don't die yet."
The fight escalated.
Zi Ji stopped holding back entirely.
Her strikes came faster, heavier, carrying the weight of a hundred-thousand-year beast that had learned restraint only by choice. Lin Huang responded instinctively, body moving before thought, cerulean aura reinforcing every motion.
For a brief, impossible span of time—
He kept up.
But the cost came swiftly.
His breath grew ragged.His core burned.
The transformation amplified everything — including consumption. Without a place to store the excess, power bled away as fast as it arrived.
Zi Ji saw it.
Her next blow struck cleanly.
Lin Huang was sent flying, crashing into the reinforced formation with a thunderous impact. The cerulean aura flickered violently.
"Enough," Gu Yuena said.
The word carried authority.
Zi Ji stopped instantly, tongue clicking in annoyance. "Tch. Just when it got fun."
Lin Huang dropped to one knee, coughing, cerulean light fading rapidly as exhaustion crashed into him.
Bi Ji was already there.
Soft green radiance enveloped her hands as she pressed them against his back and chest, life energy flowing with calm precision. Torn meridians soothed. Overheated channels cooled.
Lin Huang sucked in a breath. "You're fast."
"You're reckless," Bi Ji replied quietly.
He smiled despite himself. "Whoever ends up marrying you someday is going to be very lucky."
Bi Ji froze.
Then flushed bright red and shoved his forehead back with a sharp push. "Shut up and stay still!"
Laughter rippled through the courtyard.
Wu Feng shook her head. "He really doesn't know fear."
"He does," Ning Tian said softly. "He just chooses when to ignore it."
Zi Ji crossed her arms, tail swaying. "So that's integration. Crude, but promising."
Gu Yuena approached, gaze steady.
"This is not a state," she said. "It is a transformation."
Lin Huang nodded, still catching his breath. "First stage."
"And unsustainable," she added.
"For now."
Gu Yuena studied him. "You felt it."
"Yes."
"What did you lack?"
Lin Huang didn't answer immediately.
Then he looked down at his own hands.
"A place to put the excess."
Tang Ya blinked. "…That sounds familiar."
She turned and hurried inside, returning moments later with folded parchment. She spread it open on the stone.
A drawing.
A figure standing amid spiraling currents, energy drawn inward toward a marked point in the lower abdomen.
Wu Feng stared. "Isn't that from your stupid drawing?"
Lin Huang groaned. "It wasn't stupid."
Tang Ya tapped the page. "Doesn't that look like what just happened?"
Ning Tian leaned closer. "That's not amplification. That's storage."
Ji Juechen frowned. "A seal."
Zi Ji laughed. "So this really is Sage Mode."
"Not exactly," Lin Huang said. "But close."
He looked at Tang Ya.
"This isn't just for me."
She froze. "What?"
"You bleed natural energy every time you fight," he said calmly. "A reservoir would let you stabilize it."
Tang Ya's fingers tightened around the parchment.
"…You think I could use it."
"I know you can."
Wu Feng snorted. "Great. Now everyone wants one."
Gu Yuena spoke calmly. "This path is not exclusive."
Silence followed.
Four months ago, they had arrived seeking strength.
Now, they were discussing structure.
Lin Huang sat back slowly, exhaustion still heavy but controlled.
"This isn't something I can rush," he said. "But I won't stop either."
Gu Yuena inclined her head. "Then we proceed properly."
The sun dipped lower.
The courtyard, cracked and marked by the fight, felt strangely right.
Not borrowed.
Not temporary.
Earned.
The courtyard didn't return to normal after the fight.
Not immediately.
Cracks still traced the stone where Zi Ji's strength had met Lin Huang's incomplete transformation. The reinforced formations hummed faintly, slowly dissipating excess force. Dust lingered in the air longer than it should have, refusing to settle as if the space itself needed time to accept what had just happened.
No one rushed to fix it.
That, more than anything, marked the change.
Four months ago, damage would have meant panic, apologies, explanations. Now it meant observation.
Wu Feng squatted near one of the cracked tiles, pressing two fingers against the stone. "Still warm."
Meng Hongchen peered over her shoulder. "You broke Shrek property again."
Wu Feng shrugged. "Zi Ji broke it."
Zi Ji, reclining against a pillar with her arms crossed, snorted. "He broke it."
Lin Huang didn't respond. He was sitting on the low steps near the edge of the courtyard, Bi Ji still kneeling beside him, palm resting lightly against his back as the last traces of strain were smoothed out. His breathing had evened out, but fatigue clung to him in layers, the kind that didn't vanish just because wounds were closed.
"Don't stand yet," Bi Ji said quietly.
"I'm not planning to," he replied.
She glanced at his face, then away. "Good."
A small silence settled.
Not awkward. Not heavy.
Just thoughtful.
Ning Tian broke it first.
"You lasted longer than I expected," she said, voice calm but focused. "Against Zi Ji, I mean."
Zi Ji laughed softly. "That's because I didn't want to kill him."
"That's not comforting," Wu Feng muttered.
Lin Huang tilted his head back against the stone. "It's honest."
Ning Tian stepped closer, Pagoda shimmering faintly behind her as she studied him. "Your consumption curve was strange."
"Strange how?" Tang Ya asked, folding her arms.
"It spiked fast," Ning Tian said. "But it didn't collapse. You weren't leaking randomly."
Lin Huang nodded slowly. "Because I cut it off early."
"And because you were compressing," she continued. "Even without a proper seal, you were already trying to contain it."
Zi Ji's ears twitched. "So you weren't just glowing blue for fun."
"It's cerulean," Meng corrected automatically.
Wu Feng rolled her eyes. "I don't care if it's turquoise."
Lin Huang smiled faintly despite himself.
Gu Yuena had remained silent, standing near the far edge of the courtyard, silver eyes reflecting the fractured stone and the people standing within it. When she finally spoke, everyone listened.
"You are all reacting to the effect," she said calmly. "Not the cause."
Tang Ya frowned slightly. "The cause being…?"
"Four months," Gu Yuena replied.
That made several of them pause.
"Four months since you arrived here," she continued. "Four months of continuous adaptation. Training. Conflict. Adjustment. You are no longer operating as isolated cultivators."
Ji Juechen inclined his head slightly. "We noticed."
"You noticed the results," Gu Yuena said. "But not the shift in method."
She looked at Lin Huang.
"You are no longer asking how to become stronger," she said. "You are asking how to handle strength."
Lin Huang didn't deny it.
"That's because I don't want this to be temporary," he replied. "Not for me. Not for them."
Wu Feng straightened slightly. "You mean that thing you were talking about earlier."
"The reservoir," Meng said.
"The seal," Tang Ya corrected, tapping the folded parchment she still held.
"The system," Ning Tian added quietly.
Lin Huang glanced at her, then nodded. "Yes."
That word—system—hung in the air.
Not as an explanation.
As a direction.
He pushed himself up slowly, testing his balance. Bi Ji stayed close but didn't stop him this time. His legs trembled slightly before settling.
"I don't want this to be something only I can use," Lin Huang said. "If it were, it would fail."
Wu Feng snorted. "That's a bold assumption."
"No," he replied calmly. "It's a realistic one."
He turned to Tang Ya. "You're already drawing natural energy every time you fight. Without a place to store surplus, it bleeds off. That's why your techniques scale horizontally instead of vertically."
Tang Ya's expression shifted—not defensive, not offended.
Interested.
"So you're saying," she said slowly, "if I had somewhere to keep it…"
"You wouldn't need to rush activation," Lin Huang finished. "You could prepare once, then deploy when needed."
Her fingers tightened around the parchment again.
"That's exactly what that drawing was missing," she murmured.
Wu Feng crossed her arms. "And you think this would help me too."
"Yes."
She tilted her head. "Dragon Essence doesn't like being caged."
"I'm not talking about caging it," Lin Huang replied. "I'm talking about giving it room."
Zi Ji laughed quietly. "You're really saying this to a dragon."
Wu Feng shrugged. "He's not wrong."
Meng leaned against the railing. "So this isn't about making the blue state stronger."
"No," Ning Tian said softly. "It's about making it last."
Lin Huang nodded.
"And making it optional," he added. "Not something I'm forced into every time I fight seriously."
Gu Yuena stepped forward then, silver gaze sharp.
"You understand the implication," she said. "Once you formalize this into a usable system, it will not remain private."
"I know."
"Others will imitate it."
"I expect them to."
Zi Ji raised an eyebrow. "You're awfully calm about that."
Lin Huang met her gaze. "Because imitation without understanding is harmless."
That earned a low chuckle from Ji Juechen.
"Arrogant," Wu Feng said.
"Practical," Ning Tian countered.
They moved inside as the sun dipped lower, the conversation following them naturally, fragments of thought carried across rooms and corridors. Someone brought tea. Someone else complained about dust. Life resumed—not in spite of what had happened, but alongside it.
Tang Ya spread the parchment on the long table this time, weighing it down with a cup so it wouldn't curl.
"This part here," she said, pointing to a spiral near the lower abdomen. "In your drawing, the energy flows continuously. That's not realistic for us."
Lin Huang leaned over her shoulder. "Agreed."
"But if we treat it like a project instead of a technique," she continued, eyes bright now, "we can define phases. Accumulation. Stabilization. Release."
Ning Tian stepped closer. "Like managing Soul Power distribution."
"Exactly."
Wu Feng frowned. "This is starting to sound like homework."
Xiao Hongchen, who had been quiet until now, looked up from the small device he was adjusting. "It is."
Everyone looked at him.
He shrugged. "If it's a system, it can be optimized."
Ju Zi's eyes lit up. "And standardized."
Su Mei, standing near the doorway, smiled faintly. "And sustained."
Bi Ji tilted her head slightly. "And recovered from."
The table grew crowded as they leaned in, voices overlapping—not arguing, not competing, but building.
Lin Huang watched them for a moment before speaking again.
"There's something else," he said.
They quieted.
"This isn't limited to Soul Power."
Tang Ya blinked. "You mean…?"
"Natural energy," he said. "Ambient vitality. Elemental overflow. Anything that doesn't fit neatly into our circulation."
Gu Yuena's gaze sharpened.
"That is a dangerous statement," she said calmly.
"Yes," Lin Huang replied. "But a true one."
Zi Ji smirked. "Now you're talking my language."
"No," Gu Yuena corrected. "He's talking about balance."
Ning Tian exhaled slowly. "If this works…"
"It won't be fast," Lin Huang said immediately. "And it won't be easy."
Wu Feng snorted. "Nothing about you ever is."
He smiled. "But it won't be exclusive either."
Tang Ya folded the parchment carefully this time, her movements deliberate. "Then we start small."
"With who?" Meng asked.
Tang Ya didn't hesitate. "Me."
Wu Feng opened her mouth to protest, then closed it again.
"…Fine," she said. "But I'm next."
Ji Juechen crossed his arms. "I don't need it."
Lin Huang glanced at him. "Not yet."
Ji Juechen paused, then nodded once. "Fair."
Gu Yuena observed all of this without interruption, silver eyes thoughtful.
"This will change your pace," she said finally. "Once you begin treating growth as a managed process, you will no longer advance by impulse."
"That's the point," Lin Huang replied.
She studied him for a long moment, then inclined her head slightly.
"Very well," she said. "We proceed carefully."
The conversation slowly dispersed after that—not because it was finished, but because it had reached a natural pause. Some went to rest. Some returned to training. Some simply sat and thought.
Lin Huang stepped out onto the balcony alone as evening settled fully over Shrek City. Lights flickered on below, one by one, orderly and distant.
Four months.
He flexed his fingers, feeling the faint echo of cerulean alignment still lingering deep within, not active, but remembered.
It wasn't power he had gained today.
It was direction.
Behind him, the mansion murmured with quiet life—arguments, laughter, planning. None of it felt rushed. None of it felt fragile.
They weren't chasing growth anymore.
They were designing how to carry it.
And once a system like that took shape, it didn't disappear easily.
Night settled over Shrek City with a patience that felt earned.
From the balcony, Lin Huang watched the city lights arrange themselves into patterns he no longer bothered to memorize. Four months ago, everything beyond the academy walls had felt provisional—temporary lodging, borrowed influence, borrowed calm. Now the city simply existed around them, indifferent in the way only something stable could be.
Behind him, the mansion had quieted into its late rhythm. Not silence, exactly. More like a low, constant murmur—footsteps moving to familiar rooms, the faint clink of cups, someone arguing quietly about nothing important.
Gu Yuena joined him without sound.
"You're not resting," she said, not accusing, merely observing.
"I am," Lin Huang replied. "Just not lying down."
She took the space beside him, silver eyes reflecting the scattered lights below. For a while, neither spoke. The pause felt deliberate, not empty.
"You didn't mention the rest," Gu Yuena said at last.
Lin Huang smiled faintly. "I wanted to see how far the conversation would go without it."
"And?"
"They went where I hoped. Just not far enough."
She turned her head slightly. "Then speak."
He leaned his forearms against the railing.
"The seal we talked about earlier," he began. "The reservoir. It's only one piece."
Gu Yuena didn't interrupt.
"I'm not interested in treating energy as something that only flows," Lin Huang continued. "Flow is inefficient. It leaks. It forces timing. If you miss the window, you lose everything you gathered."
She studied him more intently now.
"You want to fix it in place," she said.
"Yes."
He turned to face her fully. "Not suppress it. Not bind it. Solidify it."
The word hung between them.
Gu Yuena's expression didn't change, but the air did. Subtle. Attentive.
"Explain."
"Any energy," Lin Huang said calmly. "Soul Power. Natural energy. Elemental overflow. Even Dragon Essence. If it can exist stably in circulation, it can be crystallized."
"That is not how cultivation has ever worked," Gu Yuena said.
"That's because no one treated energy like a material," he replied. "They treat it like breath."
She was silent.
Lin Huang continued, carefully. "I don't mean permanently. Crystallization doesn't have to be absolute. It can be reversible. A storage state. A battery."
"A crystal," Gu Yuena said slowly.
"Yes. A Soul Crystal."
She looked back out at the city. "You realize what you are suggesting."
"I do."
"You are removing energy from the cycle," she said. "From circulation. From natural loss."
"I'm delaying it," Lin Huang corrected. "Not erasing it."
She turned back to him. "And you believe this can be done safely."
"I believe it can be done cleanly," he replied. "Safety comes from design."
Gu Yuena watched him for a long moment.
"You speak of this very casually," she said. "But if successful, this alone would disrupt cultivation across continents."
Lin Huang shrugged lightly. "Only for people who rely on inefficiency."
That earned him a brief, sharp glance.
"You are walking a line," she said. "Between understanding and arrogance."
"I know," he replied. "That's why I'm talking to you before trying anything serious."
Her gaze softened by a fraction.
"Good," she said. "Because this is not something you test blindly."
He nodded. "I wouldn't."
They stood there together, the night air cool but not cold.
"There's more," Lin Huang added.
Gu Yuena sighed softly. "Of course there is."
He smiled. "The artificial Soul Bone."
That made her turn fully toward him.
"Say it properly," she said.
"The artificial Soul Bone," Lin Huang repeated, unhurried. "Forged externally. Built around a lineage-based Soul Core."
Her eyes narrowed slightly. "You are certain of the order."
"Yes," he replied immediately. "The core comes first. Without it, a bone is just shaped material."
"And the core," she said, "would be made from—"
"Refined blood or lineage essence," Lin Huang finished. "Of a compatible Soul Beast. Stabilized. Structured. Then anchored."
Gu Yuena was quiet for several seconds.
"This is not new," she said at last.
Lin Huang blinked. "It isn't?"
"The concept," she clarified. "Not the execution. Ancient beasts understood something similar instinctively. But they never formalized it. Never made a project out of it."
He exhaled slowly. "That explains a lot."
"You are not inventing," Gu Yuena continued. "You are organizing."
"That seems to be a recurring theme," he replied.
She studied him, silver gaze sharp but no longer hostile.
"With sufficient purity," she said, "and sufficient cultivation level… an artificial Soul Bone could indeed reach high age."
"Even a hundred thousand," Lin Huang said.
"Yes," Gu Yuena confirmed. "But do not misunderstand. That does not make it trivial."
"I don't expect it to be."
"You will need extremely pure energy," she continued. "Which brings us back to your crystals."
Lin Huang nodded. "Exactly."
Soul Crystals.
A method to solidify excess energy into a stable form. To feed formations. To fuel cultivation. To support external projects without draining the cultivator directly.
"And Dragon Essence?" Gu Yuena asked.
He met her gaze. "It can be crystallized too. Not easily. But it can."
She laughed softly, a sound without mockery.
"You truly do not fear dragons."
"I fear inefficiency," he replied.
That earned him a longer look.
"This will not stay hidden," Gu Yuena said eventually. "Even if you do not announce it."
"I don't need it to," Lin Huang replied. "Results speak."
She nodded once. "Very well. When you begin this project, I will observe."
"Observe?" he asked.
"And intervene if you are about to do something foolish."
He smiled. "That's fair."
They returned inside not long after.
The mansion was quieter now, most of the group having retired. A few lights remained on. Ju Zi's room, unsurprisingly. Su Mei's as well.
Lin Huang passed through the training hall instead of heading to his room.
The space was empty, open, familiar.
He stood in the center and took a slow breath.
Rasengan was a bad name.
He knew that.
It was flashy, childish, tied to a story he had half-drawn, half-forgotten. But the concept had stuck with him for a reason.
Rotation. Compression. Containment.
"Spiral Bullet," he murmured instead.
Bala Espiral.
He raised one hand.
Soul Power gathered, not explosively, but carefully. He didn't pull much. Just enough to test.
The energy began to rotate.
At first, it wobbled, threatening to disperse. He adjusted, reducing output, focusing on shape instead of force. The rotation stabilized slightly, forming a loose, spinning mass above his palm.
It collapsed almost immediately.
Lin Huang frowned, then relaxed.
"Again."
This time, he added a trace of Kitsune Essence, not to amplify, but to guide. The rotation tightened. The sphere grew denser, humming faintly.
His wrist trembled.
Too much.
The sphere destabilized and burst, dissipating harmlessly.
Lin Huang exhaled and shook his hand once.
"Still inefficient."
He tried again.
And again.
Each attempt lasted a heartbeat longer. Each failure taught him something new about control. About pressure. About how energy resisted being shaped when treated like force instead of matter.
After the seventh attempt, he managed to hold it for three full seconds.
The sphere was small. Barely larger than a fist. But the pressure within it was unmistakable.
"Interesting."
He released it deliberately, letting the energy flow back into circulation.
No backlash.
No strain.
"Storage and shape," he muttered. "Same principle."
A soft clap echoed from the doorway.
Zi Ji leaned against the frame, watching with amused interest. "You really don't know how to rest."
Lin Huang didn't turn. "I rest differently."
She walked closer, peering at his hand. "That thing dangerous?"
"Eventually."
She grinned. "Good."
Gu Yuena appeared behind her, silent as ever.
"You are practicing containment," she observed.
"Yes."
"And you intend to pair it with your seal project."
"Yes."
She nodded slowly. "Consistent."
Zi Ji snorted. "You two sound like you're reviewing homework."
Lin Huang finally turned, smiling faintly. "That's because we are."
Gu Yuena's gaze lingered on the empty space above his palm, as if imagining what it could become.
"Do not rush," she said.
"I won't."
"Projects fail when ambition outruns patience."
Lin Huang inclined his head. "Then I'll make patience part of the system."
She regarded him for a long moment, then turned away.
"Good," she said simply.
As the hall fell quiet again, Lin Huang lowered his hand and let out a slow breath.
Four months.
Not long.
Not short.
But long enough to stop asking if something was possible.
And start asking how to build it properly.
