The Extra is a Genius!?-Chapter 540: The Factory at the Heart [II]

The doors slid open with a muted hum that felt almost reluctant.

The moment Selene stepped inside, she slowed, her posture changing in a way Elena recognized instantly. Not fear. Not tension. Focus. The air in the chamber was heavier, not in pressure but in intent, the shard-lines converging overhead and beneath the floor into a dense lattice of crystal and metal that surrounded a suspended core. Sigils etched into every surface glowed faintly, cycling through patterns that felt measured rather than active.

Elena stopped beside her.

"...This isn’t a normal control room," she said quietly, eyes moving across the structure. "I don’t even think it’s meant for people to stay in for long."

Selene didn’t answer right away. She walked closer, careful not to touch anything, letting her perception spread outward. The magic here wasn’t aggressive. It didn’t push back. It simply was, layered and stable in a way that made her uneasy.

"It’s not producing energy," Selene said at last. "And it’s not distributing it either. That’s what’s throwing me off."

Elena frowned. "Then what is it doing?"

Before Selene could answer, Noel and Elyra entered the chamber behind them. The door sealed shut with a soft click, cutting off the distant industrial noise and leaving the room wrapped in a low, steady hum.

Noel took one look at the suspended structure and exhaled slowly. "So this is the center."

Elyra crossed her arms, eyes narrowing as she followed the shard-lines with a strategist’s attention. "Everything routes through here. Even the sections you shut down outside," she said to Noel. "This place is still intact."

Selene nodded faintly. "Because it’s not a machine in the way we think of machines."

She gestured toward the lattice. "The shards aren’t power sources. They never were. They’re anchors."

Elena turned sharply to her. "Anchors for what?"

Selene hesitated—not because she didn’t know, but because saying it out loud made it real. "For a ritual," she said finally. "A big one."

Elyra let out a short breath. "Define big."

Selene swallowed. "Continental."

Noel didn’t react outwardly, but his grip on Revenant Fang tightened slightly. "So all those shards spread across Elarith..."

"...are points in a single formation," Selene finished. "Spread out so no one notices what they’re part of."

Elena stepped closer to the basin beneath the core, her senses brushing the residual flow cycling through the system. Her expression shifted, the relief she’d felt earlier draining away. "It’s drawing mana," she said slowly. "But not violently. Not like a siphon."

"How, then?" Noel asked.

"From inside the body," Elena replied. "Small amounts. Constantly. Enough that people feel tired, unfocused, worn down—but not enough to kill them outright." Her voice tightened. "Across a whole continent... that’s an absurd amount of power."

"And not just mana," Selene added quietly. "Life resonance. Soul imprint. Everything a summoning ritual needs."

Elyra stared at the structure, jaw set. "So this whole city—this factory—isn’t about production."

"No," Selene said. "It’s preparation."

Noel looked up at the suspended core, the sigils cycling like a patient heartbeat. "Preparation for what?"

Selene met his eyes. "To open a passage. To pull something through."

Elena didn’t hesitate. "Elarith."

The name settled into the room like dust.

For a moment, none of them spoke. Not because they were shocked—they’d all suspected something like this—but because the scale of it refused to stay abstract now that it had a shape.

"This isn’t a weapon," Elena said softly. "It’s an altar."

"One fed by an entire continent," Elyra added. "And the worst part?" She glanced at Noel. "It doesn’t even need someone standing here to activate it."

Noel nodded slowly. "The Second Pillar was maintaining it. Not controlling it."

"Yes," Selene said. "And now it’s dormant. Not stopped."

Elena’s hands curled into fists. "If we just destroy it—"

"It collapses," Selene said immediately. "And everyone still linked to the network collapses with it."

Noel closed his eyes for a brief moment, then opened them again. "So we don’t break it."

"No," Selene agreed. "We dismantle it. Carefully. Node by node."

Outside the chamber, the hum of the factory faltered again as another section shut down, the altar remaining suspended, untouched and whole.

They didn’t leave the chamber right away.

Instead, they circled the suspended structure slowly, tracing shard-lines with their eyes, watching how the sigils shifted in response to flow changes deeper in the factory. Elena crouched near one of the consoles built into the floor, brushing dust aside to read markings that hadn’t been meant for casual use. Selene stood nearby, hands folded behind her back, following the lattice with quiet concentration.

Noel tried.

He really did.

He stared at the patterns, the layers of interlocking geometry, the way the shards pulsed in sequences that clearly meant something... and felt absolutely nothing click into place. It was like watching someone else’s handwriting upside down.

"This is... complicated," he said at last, rubbing the back of his neck.

Selene glanced at him. "That’s one way to put it."

"I mean, I get the idea," Noel continued, gesturing vaguely at the altar. "Don’t break it all at once. Take it apart slowly. Don’t kill a continent. That part’s clear." He paused. "The rest of it might as well be written in another language."

Elena snorted softly before she could stop herself.

Noel shot her a look. "Hey."

"I’m sorry," she said, trying—and failing—to look apologetic. "It’s just... you’re staring at it like it personally offended you."

"It did," Noel replied. "By existing."

Elyra leaned against one of the support pillars, arms crossed, watching the exchange with an amused glint in her eyes. "You know," she said casually, "this is exactly the face you used to make back at the academy."

Noel froze. "What face."

"That one," she said, nodding toward him. "The ’I have no idea what’s happening but I’m pretending I do’ face."

Elena laughed outright this time. Selene’s lips twitched.

Noel sighed. "That’s unfair."

Elyra tilted her head, clearly enjoying herself. "I still remember when Daemar let you copy during the exam."

Noel blinked. "You saw that?"

"Of course I saw it," she said. "You were terrible at hiding it. You leaned so far over I thought you were going to fall out of your chair."

"That was strategic," Noel muttered. "Risk management."

"It was hilarious," Elyra replied sweetly.

Elena covered her mouth, shoulders shaking. Selene looked away, but not fast enough to hide the faint smile.

Noel glanced back at the altar, then at them. "...You know, for the record, I still don’t like studying."

"And yet," Elyra said, pushing off the pillar, "you’re going to have to learn this one."

Noel exhaled slowly, eyes returning to the shard-lines. "Yeah," he said. "Guess I am."
