Genetic Engineer in a Tamer's World

The grand colosseum of Emberheart was a sea of shifting colours and deafening noise. Tens of thousands of spectators packed the tiered stone benches rising towards the sky. The air was thick with the scent of roasted meats, sweet wines, and volatile magical energy.

Golden imperial banners fluttered along the outer walls, their embroidered phoenix symbols catching the morning light. On the high royal dais, the royal siblings sat with visible poise. Prince Renard was laughing with a group of noble ministers, his red hair gleaming.

Beside him, Princess Aria sat with her golden fan resting against her chin. Her yellow eyes scanned the arena below with quiet and analytical precision. Her gaze occasionally drifted toward the southern platform, searching for a familiar figure.

The sibling rivalry between the two was a silent, tense current beneath the warmth of the music and laughter. They were locked in a race for the imperial throne, and every word was a calculated move. Renard frequently turned his attention to his noble allies, while Aria countered with soft, sharp observations.

Kale Ardentis stood near the edge of the Artificer section, his posture calm and upright. He wore his gold-trimmed Master robes, the fabric stiff and immaculate. On his shoulder, Neo sat in his compressed chameleon form, its golden eyes watching the crowd.

Beneath the fabric of his robes, the permanent subcutaneous seal on his neck hummed softly. The dual elements of the Terra Shell and the Ignis Core worked in perfect harmony. They kept his physical frame fully stable and anchored against the curse.

His physical frame felt perfectly stable, the dual pathway system keeping the World Dragon’s curse fully anchored. To complete the next phase of his elemental ascension, he required more than basic materials. He needed to win the ancient core at the competition.

A loud trumpet blast echoed through the arena, silencing the murmurs of the crowd. Grandmaster Kraul stood at the edge of the presenter platform, his booming voice carrying over the seats.

”Silence,”

Kraul commanded, his gaze sweeping over the young competitors.

”Today begins the Grand Imperial Zenith Competition. The first trial of the Artificer path is the Test of Thermal Resistance. You must present a completed tool capable of regulating volatile elemental mana without leaking a single unit of energy.”

The announcement triggered a low murmur of anticipation from the benches. This first trial was notoriously difficult, designed to eliminate any candidate whose mana control was lacking. The judges would subject each crafted tool to a concentrated fire surge.

The prompt was notoriously difficult, requiring a perfect synthesis of design and material stability. One minor miscalculation in any field would cause a chain reaction, shattering the matrix and reducing the tool to ash. Most candidates spent months preparing specialised stabilisers to survive.

Grandmaster Oram stood beside Kraul, taking over the explanation with a pleasant smile.

”We will test your creations under three distinct stages of thermal stress.”

Oram explained.

”If your tool shows even a minor instability or crack, you will be disqualified. Step forward when your number is called.”

The first candidate was the genius heir of House Morrow. He walked to the testing pedestal with an arrogant smile, carrying a heavy, earth-attributed talisman. The talisman was carved from deep earth granite, humming with a stable mana signature.

The testing assistants aligned the copper towers with the Morrow talisman. A beam of concentrated fire mana erupted from the towers, slamming directly into the stone. The talisman glowed bright red, its earth runes absorbing the heat.

”Initiating second stage surge.”

The assistant announced, increasing the power to 60%.

The fire beam thickened, the intense heat making the stone pedestal groan. The Morrow talisman began to vibrate, its outer edges turning a dark grey as it struggled to distribute the elemental load across its dense mineral structure.

”Take it to the peak stage,”

Kraul growled, leaning over the railing.

The final surge of fire was blinding, a pillar of pure orange light that enveloped the talisman. A sharp crack echoed through the quiet arena, and the Morrow talisman split down the middle, leaking a small trail of grey smoke.

The heir’s face went pale as Oram shook his head in pity.

”Disqualified,”

Oram noted.

”The structural integrity failed under peak stress.”

Next came the competitor from the Divine Fist Sect. He presented a fire-infused brass core, designed to withstand extreme thermal expansion. The testing began, and his core managed to survive the second stage, but melted into a pool of liquid metal during the peak surge.

One by one, the young prodigies of the capital stepped forward, only to have their pride crushed. The demanding standards of the Grandmasters left no room for error. Out of fifty candidates, only three managed to survive the test temporarily.

The audience watched in rising apprehension as the failures accumulated. The noble families in the benches began to whisper in concern, realising that the trial was far more brutal than in previous years. The Grandmasters showed no mercy to the weak.

”Number one hundred and eleven, Kale Ardentis,”

the assistant called out.

Kale walked toward the central pedestal, his movements carrying a fluid and predatory grace. The crowd watched him in silence, many of them recognising the green-haired tamer who had humiliated the noble recruits in the training arena.

He placed his completed creation onto the wooden pedestal. It was the Aether Granite Lens. The tool was a beautiful, flawless work of master engineering, its surface glowing with a quiet harmony of deep red and granite grey.

The Morrow heir sneered from the sidelines, his voice carrying a sharp edge of jealousy.

”A tamer thinks he can pass where true artificers have failed,”

the noble muttered.

”That lens will shatter into dust the moment the fire touches it.”

Kale ignored the comment, his green eyes remaining calm as he stepped back. He adjusted his grey headband, ensuring the gold mesh on his neck was fully masked. He commanded Neo to remain still, and the hydra compressed its energy.

The assistants aligned the copper towers with the Aether Granite Lens, their tips sparking with fire mana.

”Initiating first stage surge.”

The assistant announced, unleashing the beam.

The fire mana slammed into the lens. Instead of resisting the heat, the Aether Granite Lens absorbed the energy instantly. The volcanic resin coating glowed with a brilliant crimson light, distributing the thermal load evenly across the carved silver alloy frame.

Instead of carving rigid lines, Kale utilised his understanding of cellular networks to etch curved, organic channels. These pathways mirrored the natural blood vessels of high-level beasts, allowing the mana to flow without hitting sudden corners.

”Increase to 60%,”

Kraul ordered, his eyes narrowing.

The fire beam thickened, the intense heat making the air around the pedestal shimmer. The Aether Granite Lens continued to pulse, its organic, curved runic channels directing the fire mana toward the deep earth crystal at its core, creating a perfect balance.

The lens showed no sign of strain. It acted like a thermodynamic filter, absorbing the volcanic energy and focusing it into a thin, laser-like beam of pure red light that shot harmlessly into the sky.

”Take it to the absolute peak,”

Kraul growled, his voice carrying a rare excitement.

The final surge of fire was a blinding pillar of light that obscured the pedestal entirely. The heat in the arena rose to an uncomfortable level, forcing the spectators in the front rows to shield their faces from the thermal wave.

The surge ended, the copper towers humming as they powered down. When the smoke cleared, the Aether Granite Lens was still sitting perfectly intact on the pedestal. It was glowing with a brilliant, steady light, its structure completely undisturbed.

There was not a single crack in the silver alloy frame, nor a single scorch mark on the deep earth crystal. The integration of the earth and fire elements was absolute, a perfect display of masterwork craftsmanship.

Oram stood up, his pleasant face carrying a mixture of awe and profound respect.

”Flawless,”

Oram announced.

”The energy distribution is perfectly balanced. I have never seen such a clean synthesis from a candidate in the first trial.”

Kraul let out a low rumble of approval, nodding his head.

”The toolcraft engraving is precise, and the choice of volcanic resin was handled with master level competence. You have passed, boy.”

From the royal dais, Princess Aria smiled, her yellow eyes gleaming with a knowing and highly intrigued light. She tapped her golden fan against her palm, her gaze locked onto the green-haired young man who had just shocked the capital.

Prince Renard let out a boisterous laugh, raising his goblet to toast Kale’s success.

”Well played, tamer!”

Renard bellowed, his voice carrying over the crowd.

”A masterwork indeed!”

The other recruits were staring at Kale in pure shock, their arrogance now replaced by a crushing sense of inadequacy. Julian, the son of the general, looked at the lens in wonder, realising that he had never stood a chance.

Kale offered a formal half bow to the panel of examiners, his expression remaining a mask of stoic detachment. He stored the Aether Granite Lens into his spatial pouch, his mind already calculating the parameters of the second trial.

The first step of the grand Zenith Competition was finally complete. With his masterwork validated and the royal siblings closely watching his progress, the determined Genetic Engineer prepared for the next challenge, ready to claim the ancient rank core and secure his absolute salvation.
