Heretic Trainer: The Gym Is My Cultivation Method-Chapter 421: Young Master Found Worse Idea

Darrell and his group walked deeper into the underground passage until they reached a massive stone door.

The surface of the door was carved with strange markings, dark and twisted, unlike anything used by Draconia.

The assistant stepped forward and pressed his palm against a hidden groove.

Mana flowed briefly through the lines, and the door slowly opened with a heavy grinding sound.

Cold air rushed out, and from inside the chamber, a massive shape moved.

Clara’s eyes widened slightly from the shadows where they were hiding.

Eliza stiffened beside her.

A huge black dragon lay coiled in the center of the cavern.

Its scales were dull and dark, and faint demonic energy seeped from the cracks between them.

Its eyes opened slowly, glowing red in the dim light.

Dahlia narrowed her eyes.

Before anyone could speak, Darrell suddenly raised his hand.

The Draconia soldiers behind him moved instantly.

Blades flashed.

The pirates who had followed them didn’t even have time to react. "What?!"

One pirate tried to turn, but his throat was cut cleanly.

Another stumbled backward before collapsing, blood spreading across the stone floor.

Within seconds, all the pirates were dead.

Clara blinked. "That’s cold."

Eliza didn’t speak, but her expression sharpened.

Darrell smirked as he looked down at the bodies.

He stepped forward toward the dragon and bowed slightly. "Demonic Dragon Navrel."

His voice echoed in the cavern. "We from Draconia have come."

He gestured to the crates his men carried forward. "We have brought food and resources. As promised."

The black dragon lifted its massive head slightly. Its eyes locked onto Darrell first, then shifted slowly across the chamber.

"Good," Navrel said in a deep voice that vibrated through the stone.

It glanced at the crates. "What do you want, member of Draconia?"

Behind a stone pillar near the entrance, Eliza crouched low, invisible under her skill, watching carefully.

Dahlia and Clara stayed just behind her, hidden in shadow.

All three frowned.

Dahlia’s eyes didn’t leave the dragon.

"No wonder," she whispered quietly.

Clara glanced at her. "No wonder what?"

Dahlia’s gaze hardened. "This feeling."

She placed a hand lightly over her chest. "It’s the same as when I was in the Demon World with Master."

Clara blinked. "Oh."

She looked back at the dragon. "So that’s why it felt familiar."

The demonic aura in the room was thick and unstable.

Clara swallowed once. "So... what do we do now?"

Dahlia’s lips curved slightly. "Wait."

She leaned casually against the stone, but her eyes remained sharp. "It’s only a demonic dragon."

Clara stared at her. "Only?"

Dahlia’s smirk deepened. "If Master can kill a Demon Count..."

She cracked her knuckles quietly. "Then this is just a warm-up."

Inside the chamber, Darrell stood tall before Navrel, unaware that three disciples of God Gym were watching everything unfold.

Darrell kept his chin high.

"Demonic Dragon Navrel," he said clearly, "I want power."

His voice echoed against the walls. "I want to destroy God Gym."

Navrel lifted one heavy eyelid slowly. A low rumble escaped its throat.

"God Gym?" the dragon repeated. "Who are they?"

Darrell’s lips tightened.

"A new Grand Faction," he replied. "They rose after destroying a Demon Gate."

The moment Navrel heard that, its head lifted higher. The air in the chamber shifted slightly.

"They destroyed a Demon Gate?"

Its voice grew sharper. "Are you joking, human?"

Darrell shook his head firmly. "No."

He stepped closer, not showing hesitation. "From what I heard, their sect master, Garion, destroyed the Demon Gate single-handedly."

Navrel’s red eyes narrowed.

For a few seconds, it didn’t speak.

A person who can destroy a Demon Gate...

The dragon’s claws dug slightly into the stone floor.

"To think such a person exists," Navrel muttered.

Behind a stone pillar near the entrance, Eliza stayed perfectly still. Dahlia and Clara remained crouched low behind her.

Clara glanced at Dahlia quietly.

"That’s new," she whispered.

Dahlia’s eyes remained fixed on the dragon. Her expression did not change.

Back in the center of the chamber, Navrel slowly turned its head toward Darrell again. "And you want to fight them?"

Darrell’s jaw tightened. "Yes."

Navrel’s lips curved slightly in what almost looked like a smile. "Interesting."

The dragon leaned forward slightly, lowering its massive head closer to Darrell. "Very well, member of Draconia."

Its voice rumbled through the stone. "I will help you."

Darrell smirked immediately. "Good."

He felt heat rise in his chest. Finally.

This dragon, Navrel, was not ordinary.

Long ago, the first Patriarch of Draconia had defeated it in battle.

That victory was one of the reasons Draconia rose to Grand Clan status.

But Navrel had been too powerful to kill. Instead, it was sealed beneath this hidden island.

Only the main lineage of Draconia knew this secret.

Over the years, they occasionally borrowed its power during desperate moments.

But using Navrel’s strength always required a dangerous price to pay, and that was why it was rarely used.

Darrell clenched his fist slightly. His father was too cautious.

If the Patriarch had used Navrel’s power openly, Draconia would not be in this weakened position now.

Darrell lifted his chin slightly and looked straight into the dragon’s glowing eyes.

"Now," he said firmly, "what can you do for me, Demonic Dragon Navrel?"

Navrel’s lips curved into a slow, sharp smile. A low rumble vibrated through its chest.

"This time," the dragon said, "I will help you by destroying God Gym."

Darrell’s smirk returned.

"But," Navrel continued, its voice deep and heavy, "all these humans are not enough to fill me."

Darrell frowned slightly. "Don’t worry, Navrel. We will get more."

Navrel’s eyes shifted past him, toward the entrance of the chamber.

"There is no need to worry," the dragon said calmly. "There are already some in front of me."

Darrell’s body stiffened. "What do you mean?"

Navrel’s red eyes gleamed. Then it laughed. "Hehehe..."

The sound echoed heavily against the stone walls.

Darrell felt a chill run down his spine. His men exchanged uneasy glances. One of them instinctively reached for his weapon.

"What is it talking about?" the assistant whispered.

Navrel’s long tail scraped lightly across the ground as he continued to grin.
