Extra is the Heir of Life and Death

Chapter 225 225: Completely innocent, as if

I stood at the front of the classroom with my hands clasped behind my back and my composure hanging by a thread.

The board behind me was filled with structured notes—energy output ratios, sustainability curves, theoretical engagement timelines. Clean. Logical. Academic.

In the third row, slightly to the left, Kent was pulling a face that belonged in a children's puppet show.

I did not look at him.

I did not look at Nora either, who was sitting one seat over from him with her white hair falling over her shoulders and her blue eyes far too bright for someone pretending to be serious. She had pressed her lips together in exaggerated concentration, eyes widened just a little too much.

They were trying to make me laugh.

I inhaled slowly.

"—and therefore," I continued, keeping my voice steady, "while numerical superiority appears decisive at first glance, the efficiency gap between dualflow and Vespera fundamentally alters the engagement outcome."

Kent puffed his cheeks out.

I stared just above his head.

It was hard to keep a straight face when an idiot like Kent kept trying to make me laugh, but I was far above his level, such petty antics would not make me lau—

"Pft"

Poker face.

Poker face.

Poker—

Belle cleared her throat.

"And what's funny, Mr. Nekros?"

Her tone was calm. Professional. Completely innocent as if.

She was absolutely in on it.

Oh shit, I'm screwed.

"Nothing, ma'am," I replied smoothly.

A ripple of suppressed amusement ran through the class.

I could feel it.

Kent leaned forward slightly and mouthed something that looked suspiciously like hydrogen bomb.

I refused to blink.

"For clarity," I said, turning back toward the board as if nothing was happening, "the scenario assumes identical skill levels, identical affinities, and identical tactical awareness. The only variable is energy structure—dualflow versus Vespera."

I picked up the chalk again and drew two simple columns.

Dualflow.Vespera.

"A thousand dualflow users collectively possess numerical advantage," I continued. "However, Vespera operates on a fundamentally different energy density. It is not simply one hundred times stronger in output. It is qualitatively superior."

Kent slowly raised his eyebrows up and down.

Nora covered her mouth like she was coughing.

Belle watched me with faint amusement in her eyes.

"What was that?" she asked lightly.

"Nothing, ma'am."

"Are you certain?"

"Yes, ma'am."

I turned back to the board before my composure cracked.

"The analogy," I said carefully, "is often simplified as a gun versus a nuke. But that is misleading in terms of scale."

Kent's shoulders began shaking silently.

I refused to acknowledge him.

"To someone who has both used dualflow and witnessed Vespera in practice," I continued, voice steady, "the gap is closer to a Hydrogen bomb VS baby situation."

There it was.

A snort escaped from somewhere in the room.

I kept my gaze locked on the far wall.

"The thousand dualflow users could coordinate flawlessly. They could optimize formation. They could distribute strain across cycles to avoid burnout. But Vespera compresses energy into singularities of output that dualflow cannot structurally withstand."

Belle stepped forward slightly.

"So your answer, Mr. Nekros?"

"The single Vespera user wins, ma'am."

"And why are you so confident?"

I paused deliberately.

"Because scaling isn't linear."

That quieted the room slightly.

I let the humor settle and continued more seriously.

"Dualflow distributes energy across two channels. It enhances efficiency compared to single-flow techniques, but it remains bound by layered reinforcement. Vespera bypasses that architecture entirely. It does not reinforce—it overwrites."

Kent stopped making faces.

Nora's expression shifted from mischievous to attentive.

"In an engagement scenario," I continued, "the Vespera user could eliminate clusters rather than individuals. Area suppression would collapse formations. The thousand would be forced into reactive defense rather than coordinated offense."

I stepped slightly to the side, letting them see the board clearly.

"The initial assumption—numbers equal victory—ignores qualitative thresholds. Once a certain power density is reached, additional quantity becomes irrelevant."

Belle folded her arms.

"And what about stamina?"

"The Vespera user would consume more energy per action," I admitted. "However, the fight would not last long enough for that to matter. The dualflow users would collapse under output disparity before attrition becomes relevant."

I paused.

"And even if they didn't," I added, "fear would destabilize coordination."

A murmur moved through the class.

Belle studied me for a moment.

"Thank you, Mr. Nekros."

I inclined my head slightly.

"Yes, ma'am."

As I turned to walk back to my seat, Kent made one final exaggerated face—eyes crossed, lips puckered.

I did not look at him.

I did not.

I made it to my chair with dignity intact.

Barely.

The moment I sat down, Kent leaned toward me.

"You almost lost it," he whispered.

"I hate you."

"You said hydrogen bomb with a straight face."

"I will end you."

Nora leaned forward slightly from behind him, white hair catching the light.

"You were very serious," she said, voice innocent.

"I was presenting."

"You looked like you were about to explode."

"That was your fault."

She smiled faintly.

Belle tapped the desk lightly.

"Next."

Annalise stood from the opposite side of the room.

Brown hair, blue eyes, posture straight and composed. She carried her notes neatly stacked, expression calm in a way that suggested she had rehearsed.

She walked to the front with quiet confidence.

"Good morning," she began.

Her voice was steady, controlled.

"In contrast to Mr. Nekros's conclusion, I believe the outcome is less absolute."

Kent glanced at me, eyebrows raised.

I leaned back slightly, listening.

"While Vespera's density advantage is undeniable," Annalise continued, "the assumption that a thousand dualflow users would fail to adapt under pressure may underestimate collective intelligence."

She wrote on the board beneath my notes.

Synchronization.

Layered reinforcement.

Sacrificial buffering.

"A thousand users can rotate frontline engagement," she said. "They can create layered shields and overlapping flows to diffuse impact. While individually weaker, their collective field may reduce peak damage."

Her reasoning was structured.

Disciplined.

"Additionally," she added, "if they divide into strategic units rather than cluster formation, they can limit area suppression."

Belle nodded slightly.

"So your answer?"

"I believe the thousand dualflow users win," Annalise said calmly. "But only with optimal coordination and minimal emotional destabilization."

I respected that.

Her answer wasn't naive.

It was cautious.

She wasn't denying Vespera's superiority—she was arguing for adaptability.

She finished and returned to her seat without fanfare.

Belle scanned the room.

"Nora."

Nora blinked once, then stood smoothly.

White hair. Blue eyes. Casual confidence that bordered on theatrical.

She didn't bring notes.

Of course she didn't.

She walked to the front and stood where I had been moments earlier.

"For the sake of argument," she began lightly, "I agree with both of them."

A few students frowned.

She smiled faintly.

"If we assume perfect logic and zero fear, the thousand can theoretically win," she said. "If we assume reality, the Vespera user wins."

Kent leaned forward, interested.

"People panic," Nora continued. "Even trained fighters. Once the first few are erased instantly, coordination fractures. Even a single hesitation can collapse synchronization."

She glanced briefly at me.

"And Vespera isn't just stronger. It feels stronger. That matters."

I understood what she meant.

Presence.

Density.

The weight of it.

"The dualflow users would need absolute trust," she continued. "Not just in each other, but in their math."

A faint smile curved her lips.

"Most people trust instinct over math."

A soft ripple of amusement passed through the room.

"So?" Belle prompted.

"So," Nora said calmly, "ninety percent of the time, the Vespera user wins."

Belle tilted her head slightly.

"And the other ten?"

"If the thousand include someone who doesn't believe they can lose."

The phrasing caught my attention.

Doesn't believe they can lose.

Belief.

Chains stronger than iron.

I forced my expression neutral.

Nora stepped back and returned to her seat, brushing past Kent who whispered something that made her elbow him lightly in response.

Belle looked at the class thoughtfully.

"Interesting," she said.

She didn't declare a correct answer.

She didn't need to.

The exercise had never been about the winner.

It had been about perspective.

The bell rang shortly after.

Chairs scraped against the floor as students gathered their things.

Kent turned to me immediately.

"You were sweating."

"I was not."

"You were."

Nora smiled faintly. "He was very professional."

"Thank you," I muttered.

Belle caught my eye briefly as she dismissed the class.

There was something knowing in her expression.

Not about the fragment.

Not about the locks.

Just about the way I had answered.

I gathered my things slowly, letting the room empty around me.

The question still lingered in the air.

A thousand dualflow versus one Vespera.

Numbers versus density.

Belief versus inevitability.

As Kent nudged me toward the door and Nora walked just ahead, white hair catching the afternoon light, I allowed myself a quiet thought.

In a theoretical classroom, it was math.

In reality—

It was something else entirely.

And I had spoken from experience no one in that room could fully understand.

I kept my expression calm.

Poker face intact.

For now.
