Heretic Trainer: The Gym Is My Cultivation Method

Rynar wiped out the sweat dripping down on his face.

Rynor was also the same as he shook out his arm, still dancing on his toes.

They stood back-to-back in the middle of the wrecked street.

Across from them stood more than twenty elders.

All of them were seriously injured, but all of them were still standing.

Rynar spat to the side.

"Damn… These guys are annoying."

An elder stepped forward, flames dancing across his sword.

"You two brats… You still think you can win against us, the real Revalis Clan?"

Rynor swayed left and right, feet tapping lightly against the broken ground.

"You call yourself the new Revalis Clan? You look more like a group of old men having a tantrum than a new clan."

The elders roared and charged.

Rynar's eyes sharpened.

"Come on then!"

He threw himself forward, punching straight into the incoming flames.

The elder blocking him gritted his teeth as the shock traveled up his arms.

Rynar smirked through the fire.

"You're slow!"

He twisted his body, caught the elder by the collar, and slammed him across the street.

Rynor, meanwhile, ducked under a spear, spun on one hand, and kicked upward, flipping the elder over his shoulder.

More attackers approached, and Rynor continued to move, weaving through them and striking them with his legs.

Another elder shouted.

"Use long-range! Don't let them get close!"

A rain of [Flame Arrows] and [Thunder Bolts] filled the sky.

Rynar clicked his tongue.

"Again with these toys."

He jumped high, caught two thunder arrows mid-air, crushed them with his fists, and landed hard enough to shake the ground.

Rynor ducked behind him and flicked three flame arrows away with his foot.

But even with all that…

There were just too many enemies.

Rynar's shoulders trembled, not from fear but from excitement.

He grinned, breath heavy.

"Rynor… You thinking what I'm thinking?"

Rynor let out a low laugh, eyes glowing with challenge.

"Yeah… crazy time."

They slammed their fists together and instantly entered [Overdrive Mode]

Basically, they activated all their mana to become even stronger than before.

Their aura quickly exploded outward, forcing the elders to stumble back in shock.

"What?!"

Rynar's body blurred forward, punching so fast the air trembled.

Rynor kicked upward, spinning, sweeping elders off their feet.

But even with their enhanced forms, the battle grew fiercer.

Both twins began to suffer more injuries because they were ignoring the elders' attacks and focused on attacking.

One elder smirked through blood.

"They're strong… But they're just boys. They'll tire soon."

Rynar wiped his mouth.

"Tire…?"

Rynor stepped beside him again, boots dragging slightly.

Both twins grinned like maniacs.

"…We're just getting started."

And with one more surge of mana, they charged back into the horde.

---

Garion arrived at Revalis City like a falling star, slowing only when he reached the rooftops.

The moment he looked at the city, he noticed something odd.

"...Huh."

The entire city was empty, and only one place was crowded, and it was the area around the God Gym.

Garion narrowed his eyes and was surprised to see that Rynar and Rynor were fighting a swarm of elders.

Garion scratched the back of his neck.

"…Those two sure know how to make noise."

Then something pinged in his vision.

[Transformed Mana Core Cells: 97%]

Another ping.

[Transformed Mana Core Cells: 98%]

Garion blinked.

"What the hell? So fast?"

He rubbed his chin while watching the twins fight like madmen.

Rynar took a thunder arrow through the shoulder, but instead of slowing down, he grabbed the elder and slammed him into the ground.

Rynor flipped over a burning sword, spun mid-air, and kicked two elders at once... only to take a flame blast in the ribs.

Both twins were bleeding, panting, and still laughing.

Garion smirked wider.

"…Oh. I get it now."

He looked around the area that was filled with flame and thunder mana.

"Their bodies are being forced to adapt because they're fighting at their limit. They're literally transforming their cells mid-battle."

His smile grew sharp, as this was exactly what happened with Arden that made his awakening so fast.

"So that's another way to push their evolution, huh?"

He crossed his arms and watched silently from afar.

Even when the twins groaned in pain.

Even when burns spread across their backs.

Even when one elder smashed both of them into a wall.

Garion didn't move.

Because every second he waited…

[98.2%]

[98.6%]

[99.1%]

[99.4%]

Their bodies were getting stronger.

Their cells were screaming and transforming at terrifying speed.

Rynor barely stood upright, wiping blood from his lips.

Rynar spat a tooth out and laughed anyway.

"Rynor… you dying?"

"Nope. You?"

"Not yet."

They bumped fists.

The elders charged again, and at that exact moment...

[Transformed Mana Core Cells: 99.9%]

Garion finally stepped forward.

He appeared right between the twins and the incoming elders.

Rynar froze mid-punch.

Rynor tripped mid-kick.

"Master?!"

Garion smiled casually.

"Yo."

The elders roared:

"Kill him too!"

Garion flicked his fingers.

BOOM!

A wave of invisible force exploded outward.

Every elder dropped to their knees at once.

Their faces were smashed into the dirt, arms trembling, unable to lift a finger.

Rynar's jaw dropped.

"Master… What was that?!"

Garion rolled his shoulders.

"Gravity. I kinda figured out how to use it like a domain."

He stepped forward, each step making the ground crack.

"Basically, if I want someone to kneel… they kneel."

Rynor stared at the kneeling elders, speechless.

"Master… You're scary."

Garion lifted a brow.

"Scary? Nah."

He pointed at the twins.

"You two are the scary ones. And now…"

He smirked.

"…get ready."

Rynar gulped. "Get ready for what?"

Rynor leaned away nervously. "Master… Why are you smiling like that?"

Garion's grin stretched even wider.

"Hehehe… Your cells just hit 99.9%. So you know what that means."

The twins blinked.

"…Huh?"

A beat passed.

Then both froze as the realization hit them like a hammer.

"Oh no."

"Oh hell no..."

They didn't even finish.

A burning rush of power tore through their bodies at once.

"GAHHHHHH!"

"IT HURTS!!"

Both twins collapsed to their knees, clutching their chests as the transformation began.
