what if I'm an undead! then so what?-Chapter 61 - 4th dimensional equation

Elias stood in the center of the Valmere Hotel’s grand ballroom, its polished oak floors gleaming under soft chandelier light. The air was thick with the scent of cedarwood cologne and fresh roses arranged in crystal vases along the walls. Tall windows framed a city skyline at dusk, the fading sun casting golden streaks across the room. Mirrors lined one wall, reflecting Elias’s lean frame, clad in a tailored navy suit with a crisp white shirt unbuttoned at the collar. His golden eyes, sharp despite the fatigue etched into his jaw, scanned the bustling crew. The earlier fight with Kaien lingered in his mind, a raw pulse of adrenaline he couldn’t shake.

The photoshoot kicked into gear with a shout. "Elias! Thirty seconds!" called the studio coordinator, a wiry man clutching a clipboard. Stylists swarmed, one smoothing his lapel, another tousling his dark hair for that effortless look, a third adjusting the angle of a spotlight. Models glided past in silks and velvets—deep burgundy gowns, charcoal blazers, cream scarves that caught the light like liquid. Their faces were masks of practiced calm, but Elias caught the flicker of rivalry in their glances. The Valmere was no ordinary venue; it was a battleground for prestige, where every pose was a claim to dominance.

Elias stepped forward, the spotlight’s warmth hitting his skin. He said nothing, his silence a shield.

The backdrop was a masterpiece of elegance: rich navy drapes framed by gilded wooden panels, evoking a timeless luxury. Cameras—professional Nikons on tripods—clicked in a staccato rhythm as Elias moved. His poses were fluid yet deliberate: a tilt of the head, a hand in his pocket, a slight shift of his weight. His presence radiated controlled power, a magnetic pull that made the room feel smaller. The crew watched, captivated, as he turned, the suit’s fabric catching the light with every angle.

"God, his aura," murmured a creative director, leaning forward in her folding chair. "It’s like he *is* the brand. We’ve never had a model like this." Her pen tapped her notepad, eyes wide with awe.

Elias barely registered the praise. His thoughts kept drifting to Kaien’s words: "My creator transcended humanity." The phrase was a splinter in his mind, sharp and unyielding.

The shoot shifted to the fragrance campaign, themed "Transcendence"—a cologne blending cedar, amber, and a faint citrus spark, meant to evoke boundless ambition. Elias stepped onto a low wooden platform, surrounded by billowing white curtains that mimicked clouds. He extended a hand, fingers splayed as if reaching for something intangible. The backdrop shifted to a starlit navy canvas, painted with subtle silver flecks. The photographer, a grizzled veteran named Marco, circled him, barking orders. "Chin up, Elias! Give me that intensity—yes, hold it!"

Cameras flashed, capturing the moment. Assistants adjusted reflectors, softening the light to highlight the cologne bottle—a sleek glass vial cradled in Elias’s hand. The scent wafted through the air, grounding the ethereal setup in something tangible.

"Perfect!" Marco shouted. "That gaze—it’s like you’re staring through the lens!"

Across the room, Kaien posed on a separate set. He wore a tailored black suit, its simplicity stark yet striking. His movements were precise, almost too perfect, each step and turn calculated to draw the eye. His pale skin and sharp features stood out against the warm lighting, and the crew whispered about his uncanny grace. "He’s like a statue come to life," one stylist muttered, pinning a boutonniere to another model’s jacket. Kaien’s presence was a quiet counterpoint to Elias’s raw charisma, their contrast fueling the shoot’s energy.

The ballroom buzzed with activity. Assistants rearranged props—vases, chairs, a velvet chaise lounge—while stylists darted in to tweak collars or dab sweat from brows. The creative team huddled, reviewing shots on a laptop, their excitement palpable. "This campaign’s going to blow up," one said, zooming in on Elias’s profile. "He and Kaien together? It’s gold."

The city outside the Valmere added depth to the scene. The hotel sat in the heart of a bustling metropolis, its streets alive with taxis and pedestrians, its skyline a mix of historic brownstones and sleek glass towers. The fashion world here was cutthroat, a microcosm of ambition where brands fought for supremacy through image alone. The Valmere’s ballroom, with its crystal chandeliers and hand-carved moldings, was a stage for the elite, where every shoot was a performance of power.

As the session progressed, the crew introduced new elements. Elias posed with a leather-bound journal, its pages open to evoke a scholarly air, then switched to a silver watch, its face glinting as he tilted his wrist. The photographer pushed for variety: "Lean against the pillar, Elias—casual but commanding. Now look away, like you’re lost in thought." Elias complied, his movements natural yet magnetic, each pose drawing gasps from the crew. Kaien, meanwhile, worked a minimalist set, his black suit stark against a cream backdrop, his stillness almost otherworldly.

Hours blurred together. The team rotated setups—elegant dining tables, frosted glass panels, a faux balcony with city lights painted behind it. Elias and Kaien shared a final shot, standing back-to-back, their silhouettes a study in contrast: Elias’s relaxed power, Kaien’s precise elegance. The room erupted in applause as Marco called, "That’s a wrap!" Elias grabbed a bottled water, the cool plastic grounding him, and headed for the elevators. Kaien followed, their earlier tension a silent shadow trailing them.

The suite was a haven of understated luxury: dark wood floors, cream leather furniture, and a balcony overlooking the city’s twinkling lights. Elias sank into an armchair, his shirt half-unbuttoned, revealing the lean muscle beneath. He gestured to the chair opposite, his golden eyes fixed on Kaien as he entered.

Kaien, now in a simple gray sweater, moved with a calm that felt almost human. "I apologize for our earlier fight," he said, bowing slightly. "It was... something I was programmed to do."

Elias leaned back, arms crossed. "Fine, you’re forgiven. But no dodging this time. What did you mean—your creator transcended humanity? Spill it."

Kaien sat, hands folded. "Of course." He paused, as if sifting through memories. "My creator, Eustace Delacroix, was a scientist shunned for his obsession with dimensional mechanics. He rejected the idea that the fourth dimension is just time layered over the third. He called it a lazy assumption, hiding a deeper truth."

Elias’s eyes narrowed. "What truth?"

"After five years of relentless study, Eustace found what he called the true dimensional equation." Kaien’s voice grew steady, almost reverent. "Let me show you."

He closed his eyes, and the air seemed to thicken, as if memory itself took form.

#### Flashback: Eustace’s Lab

The lab was a cluttered chaos of chalkboards, notebooks, and scattered tools, lit by harsh fluorescent bulbs. Eustace Delacroix, a wiry man in his thirties, stood at a blackboard, his dark hair a mess, his shirt stained with ink. His eyes burned with a manic intensity as he scribbled.

"Damn it, it’s not just K plus A!" he growled, erasing a line with a furious swipe. "Every dimension needs an anchor—a point that holds it together!" He wrote frantically:

- "1D: K + A"

"K is the anchor point," he muttered. "A is a plane, like x, y, or z. Simple enough."

He added:

- "2D: K + A + A = K + 2A (Physical)"

Then, circling it, he said, "But each A has its own K, so mathematically..." He scribbled:

- "(K + A)(K + A) = K² + 2KA + A²"

He stepped back, grinning. "That’s the second dimension. Physically K + 2A, but mathematically a squared field."

His hand flew across the board for the third dimension:

- "3D: K + A + A + A (Physical)"

He paused, then wrote:

- "Mathematical: K + K + K + A + A + A = (K + A + A + A)³"

Solving it, he muttered, "(K + A + A + A)³ expands to..." He worked it out:

- "(K + A + A + A)³ = (K + 3A)³ = K³ + 9K²A + 27KA² + 27A³"

"It’s a compound field," he said, voice trembling. "Not just planes stacked—it’s exponential!"

The air shimmered. A chalk stick lifted, floating. The lights flickered, bending oddly. A calculator sparked, its screen glitching.

"Physics is fighting this," Eustace whispered. "The closer I get, the more reality breaks."

He pressed on, writing:

- "4D? Not K + A + A + A + A. It’s different."

He drew:

- "Physical: (K + A + A + A) + (K + A + A) - (K + A)"(a three dimension combines with a two dimension, however in the process a one dimension breaks off)

- "Mathematical: (K + A + A + A)³ - (K + A + A)² - (K + A)"

He solved the brackets:

- "(K + A + A + A)³ = (K + 3A)³ = K³ + 9K²A + 27KA² + 27A³"

- "(K + A + A)² = (K + 2A)² = K² + 4KA + 4A²"

- "(K + A) = K + A"

Combining:

- "(K³ + 9K²A + 27KA² + 27A³) - (K² + 4KA + 4A²) - (K + A)"

He simplified:

- "= K³ + 9K²A + 27KA² + 27A³ - K² - 4KA - 4A² - K - A"

- "= K³ + (9K²A - K²) + (27KA² - 4KA) + (27A³ - 4A²) - A - K"

- "= K³ + 8K²A + 23KA² + 27A³ - 4A² - A - K"

The room shook violently. Gravity flipped, pinning papers to the ceiling. The blackboard warped like rubber. Time halted—the clock froze for a full minute.

Eustace began to fade, his form blurring. "I’ve found it!" he shouted. "The fourth dimension—it’s real!" His voice echoed as he vanished, leaving only his words: "Kaien, I didn’t die. I moved beyond physics."

The memory dissolved. Elias sat frozen, the weight of it sinking in.

Kaien spoke softly. "I can still reach him, faintly. He exists in a paradox—present, yet untethered from our laws."

Elias leaned forward. "So the fourth dimension isn’t time. It’s... a merged imbalance, a plane extracted?"

"Precisely," Kaien said. "Solve it, and reality reshapes."

Silence fell. Elias smirked, eyes sharp. "Transcendence is escaping the math that binds us."

"Yes," Kaien replied. 𝘧𝘳𝘦ℯ𝓌𝘦𝒷𝘯𝑜𝑣𝘦𝓁.𝒸𝘰𝓂

Elias although amazed knew this wasn’t what he was searching for.

Outside, the city’s lights twinkled. Elias grabbed a wine glass, swirling it. "Next fight, no limits. Show me what a machine like you can do."

Kaien’s lips twitched. "As you wish."
