Heretic Trainer: The Gym Is My Cultivation Method

Red mana burst violently from Rynar's body, swirling and thickening until it wrapped around him like a spinning cocoon.

The air trembled as the sphere snapped shut, sealing him inside the red sphere.

A second eruption followed right beside it, and this time it was bright yellow, forming another sphere, trapping Rynor inside.

Both orbs pulsed erratically, like living hearts.

Inside, the twins screamed.

"AAAAARGH!!"

"MASTER YOU BASTAAARD!!"

Their voices echoed through the entire city, shaking windows and rattling the broken tiles on the ground.

Garion folded his arms and nodded calmly, as if listening to someone practice scales on a piano.

"Good, good. That means it's working."

The elders around the gym looked terrified.

Some flinched, some trembled, and some were pretty sure the twins were dying.

But none of them could move.

Because Garion had them locked to the ground with his gravity power.

One elder tried to lift his head.

"What... what the hell is this?!"

Garion didn't even glance at him.

The red and yellow spheres kept vibrating, shrinking and expanding in a painful rhythm.

Each pulse shook dust loose from the gym roof. Every scream from inside hit harder than the last.

"AAAHHH! MY BONES!!"

"RYNOR, I'M GOING TO KILL MASTER AFTER THIS!!"

"SHUT UP, I'M DYING TOO!!"

Garion sighed dramatically.

"You two are so noisy… Just endure it. This is the price of becoming strong."

The elders swallowed hard.

One muttered under his breath, horrified.

"P-Price…? That sounds like torture…"

Garion leaned back a little, hands behind his head.

"Torture? Nah. This is called growth."

The spheres kept jumping, sparks flying from Rynor's, while waves of heat rolled off Rynar's.

The temperature spiked so fast the elders' sweat turned to steam the moment it left their skin.

BOOM! BOOM! BOOM!

Each pulse sounded like a small explosion.

The ground cracked beneath the twins' feet inside the spheres.

Their silhouettes curled, twisted, and shook violently.

"MASTER!!"

"WE HATE YOU!!"

"GOOD! HATE ME MORE! IT BUILDS CHARACTER!" Garion shouted back cheerfully.

The elders stared at him like he was a demon wearing a human suit.

Minutes kept ticking by.

Ten minutes.

Twenty.

Thirty.

The spheres pulsed harder and harder, the light so bright that even Garion had to narrow his eyes.

And then...

CRACK.

A crack appeared on both spheres.

Garion straightened, his grin stretching again.

"Oho… here we go."

Inside the cracking spheres, the twins' screams reached a new level.

"AAAAARGHHH!!"

The two spheres trembled, bulged outward, and then finally... they shattered.

The shockwave blasted dust and rubble across the gym courtyard.

When the light faded, two figures slowly stepped out.

Rynar stood straight, chest rising and falling with heavy breaths.

His once-normal red hair now burned in a vivid flame-red, strands glowing.

Red tattoos spread across his arms and neck in branching patterns, pulsing slowly.

Beside him, Rynor swayed for a moment before stabilizing his stance.

His hair had become a striking thunder-yellow, glowing faintly with crackling sparks.

Yellow tattoos streaked across his body in jagged arcs.

Both of them were trembling, not from weakness, but from the wild, overwhelming power rushing through them.

Garion smirked, arms crossed.

"Good job, you two. Congratulations, you've awakened your [Unique Physique]."

Rynar pointed a shaky finger at him, face twisted with exhaustion and rage.

"MASTER… You never told us it would hurt THAT much!"

Rynor stomped the ground angrily, sparks flying behind him.

"You said 'like a trillion needles'... but you didn't say they'd all stab us at once!!"

Garion burst into laughter and shrugged.

"I mean… I did say trillions of needles. You just didn't believe me."

Both twins shouted at the same time.

"DAMN IT, MASTER!!"

Garion waved a hand casually.

"Relax, relax. The pain's over. What matters is the result. And your physiques look great."

He stepped closer, looking them up and down to evaluate their new power.

"Rynar, your physique is clearly flame-type. Rynor, yours is thunder-type. As expected."

He pointed toward the row of elders still crushed under gravity, unable to move an inch.

"Now… let's test how strong your new physiques are."

The twins followed his gaze.

The elders swallowed hard.

Rynar cracked his knuckles, a red glow rising from his skin.

"Oh? We get to warm up on these guys?"

Rynor rolled his shoulders, sparks dancing around his feet.

"Master… I'm starting to like this physique already."

Garion smirked.

"Good. Because those elders are your whetstones. Don't kill them. Just break their pride a bit."

Rynar raised a brow.

"Only their pride?"

Rynor grinned.

"Can we break their arms too?"

Garion shrugged.

"Use your judgment."

The elders stiffened, eyes widening in horror.

"W-Wait, hold on!"

"Let's talk about..."

But Garion lifted one finger, and he released them all.

Every elder gasped as the pressure disappeared.

Rynar and Rynor instantly leaned forward like hunting beasts freed from chains.

Rynar smirked, fire flickering from his tattoos.

"Round two."

Rynor cracked his neck, sparks snapping across the ground.

"Let's begin."

Garion watched the twins tear through the elders.

He nodded to himself, then opened their newly awakened physique windows to take a closer look.

Garion blinked.

Then he slowly smirked.

"…well, damn."

He folded his arms, eyes following the twins as they fought back-to-back.

"They're not just twins but walking natural amplifiers."

He let out a satisfied laugh.

"As long as they stick together… their power will skyrocket. This is insane."

Below, the twins shouted as they charged again.

Garion smiled wider.
