Lord of Avalon : Lost in Another World

A Quiet Afternoon Under the Sakura Tree

The soft rustling of cherry blossoms filled the air as Ardi sat beneath a sakura tree, its petals drifting lazily in the afternoon breeze. Sunlight peeked through the pink canopy, casting dappled light onto the grass-covered ground.

A peaceful moment—perfect for training.

In front of him lay an assortment of items: a ceramic cup, a clay tile, a wooden plate, a steel katana, and a single blade of grass.

His goal? To refine his Reinforcement Magecraft by enhancing each object's structural integrity.

One by one, he worked.

He held the ceramic cup in his palm, closed his eyes, and let his mana flow into it.

A translucent network of energy lines spread across the cup's surface, revealing its internal structure—tiny fractures, weak points in the material, and areas where reinforcement would be most effective.

He adjusted his flow and strengthened it.

A faint glow pulsed through the cup before vanishing.

Ardi smiled. Flawless.

He repeated the process with the tile, the plate, and even the single blade of grass—enhancing its edges until it became as sharp as a knife.

Everything was going smoothly.

That is, until he decided to experiment on his steel katana.

----------------------------------------

A Sudden Realization

Holding the katana firmly in both hands, Ardi exhaled slowly and activated Structural Analysis.

A familiar network of energy lines spread across the blade, revealing its composition, density, and areas of reinforcement.

But then—

Kawamitsu's words echoed in his mind.

"You must learn to control your energy, young lord. Without mastery, your own power may consume you."

Ardi frowned.

"Void Energy… hmm?"

Taking a deep breath, he shifted his focus.

Instead of using mana, he reached deep within himself—to the dormant energy inside his body.

The moment he touched it, a heavy, overwhelming sensation flooded his body.

Unlike mana, which felt light and fluid, Void Energy was dense, heavy, and wild—like a black ocean threatening to pull him under.

He gritted his teeth. It felt like trying to hold onto a raging storm.

"Damn… this is harder than I thought."

Attempt #1—Failure.Void Energy slipped through his grasp, dissipating before he could even bring it to the surface.

Attempt #2—Failure.He forced too much at once, causing a sharp backlash that left his muscles feeling like they were burning.

Attempt #3—Failure.The moment the energy reached his palm, it destabilized and vanished into thin air.

Attempt #4—Failure.This time, he let it flow slower, but as soon as it left his body, it disappeared completely—merging with the surrounding mana.

Ardi froze.

"Wait… what?"

Frowning, he tried again—this time paying closer attention.

He extracted a small amount of Void Energy into his palm and let it float for a second.

Then—it started changing.

Before his very eyes, the deep black energy began shifting—its hue fading into a soft, ethereal blue.

Then it vanished completely, blending into the mana around him.

"…Huh."

Ardi blinked.

So that's what's happening…

Void Energy wasn't simply dispersing.

It was being converted into mana.

Ardi leaned back against the sakura tree, processing his newfound discovery.

Void Energy wasn't just an unknown force—it was an adaptive energy.

If it could turn into mana…

Then what was stopping it from becoming other energy types?

"If I push this theory further…" Ardi mused, rubbing his chin.

"Could I theoretically use it to generate Chakra? Ki? Even Reiatsu?"

A slow grin spread across his face.

This… this was groundbreaking.

----------------------------------------

A Dangerous Experiment Begins

The sakura petals danced around Ardi as he took a deep breath, closing his eyes and focusing inward.

Void Energy.

It was different from mana—denser, heavier, and unpredictable. If mana flowed like a river, then Void Energy was like a swirling abyss, chaotic yet full of potential.

"Alright… let's try this again."

He extended his senses, reaching deep into the core of his being where Void Energy resided.

Immediately, a cold, oppressive force surged through his body, resisting his control.

His breath hitched.

It felt like he was trying to cup a storm in his bare hands.

He willed it forward—

But the moment the energy reached his fingertips, it dissipated, scattering like smoke into the air.

Failure.

This time, he adjusted his approach.

Instead of forcefully pulling the energy out, he tried coaxing it, guiding it like a thread instead of a wave.

The results?

The energy made it halfway through his arm before violently destabilizing, sending a painful jolt through his muscles.

"Urgh—!" Ardi clenched his teeth as the backlash rippled through him, his arm momentarily going numb.

Nearby, Yui and Megumi watched with concern.

"Master…" Yui floated closer, her eyes narrowing. "Are you sure this is safe?"

Megumi folded her arms, glancing at Ardi's slightly trembling fingers. "You look like you're struggling."

Ardi exhaled sharply, flexing his hand to regain feeling. "It's fine. Just… a little adjustment."

Megumi frowned. "If you pass out, I'm forcing food down your throat. I don't care if you're unconscious."

Yui giggled. "She's not even hiding her concern anymore, huh?"

Megumi's face turned slightly red. "I-I'm just saying, someone has to keep him alive!"

Ardi smiled slightly, appreciating their concern, but turned back to his experiment.

"Alright… let's try a different approach."

----------------------------------------

The Breakthrough

For his third attempt, Ardi decided to introduce an external variable.

Instead of simply extracting Void Energy, he focused on its interaction with mana from the outside world.

Slowly, he gathered a small wisp of mana from the air—watching as it flickered like a soft blue flame in his palm.

Now came the hard part.

He reached inside himself again, pulling out a faint tendril of Void Energy.

The moment the two forces met—

A reaction occurred.

The Void Energy, once heavy and volatile, began shifting.

Ardi's eyes widened as he watched it gradually turn from deep black to ethereal blue, seamlessly blending into the mana.

"No way… It's actually working."

His heart pounded in excitement as he carefully maintained the conversion process.

Little by little, the unstable Void Energy smoothed out—becoming indistinguishable from normal mana.

For ten minutes, Ardi patiently refined the technique.

And when he finally converted an entire pool of Void Energy into mana, he clenched his fist, feeling the sheer raw power coursing through his body.

He had done it.

Taking a deep breath, Ardi redirected the newly transformed mana into his katana.

The steel hummed in response.

A familiar golden glow ran along the blade as Reinforcement Magecraft activated flawlessly.

No backlash. No instability.

His theory was correct.

Void Energy could be converted into mana—and by extension, into other forms of energy.

Which meant—

If he perfected this, he could potentially use any energy system from any world.

Ardi's lips curled into an uncontrollable grin.

This… was only the beginning.
