Modern Weapons Cheat in Fantasy World

Marcus looked down on the dragon and saw that it wasn’t moving anymore. He heaved a sigh of relief. It took three Javelin missiles to defeat a dragon that a bunch of high-ranking adventurers couldn’t bring down even after pushing themselves to their limits.

"...That’s one way to end it," he muttered.

Below, the smoke slowly settled.

The dragon’s massive body lay sprawled across the ruined street, its wings twisted at unnatural angles, its chest torn open from the final blast. The fire that once surrounded it had died down, replaced by scattered embers and rising heat.

Marcus kept the launcher on his shoulder, still watching.

"...Hold position," he said. "I want visual confirmation."

"Copy," the pilot replied.

The helicopter adjusted slightly, hovering at a steady angle above the city.

Below, Seraphine stepped forward first.

Her bow remained raised, an arrow already nocked as she approached the fallen dragon.

Selene followed behind her, staff glowing faintly, ready to cast at any sign of movement.

Liora stayed beside Kael, still trying to stabilize him, though her eyes kept shifting toward the body.

"...Is it... dead?" she asked quietly.

Kael coughed weakly, barely conscious.

"...It better be..."

Seraphine didn’t answer.

She stopped a few meters away from the dragon’s head.

"...It’s down," Selene said, though her voice carried doubt.

Seraphine lowered her bow slightly, but not completely.

"...Not yet," she said. "We confirm properly."

She drew her arrow back.

Mana gathered along its tip.

"Wind Pierce—Execution Shot!"

She released.

The arrow shot forward and struck directly into the dragon’s exposed chest, sinking deep into the torn flesh.

Seraphine held her gaze on it for a few seconds longer.

Then, she slowly lowered her bow.

"It’s over."

Selene let out a breath she didn’t realize she was holding.

"That’s it?"

Liora slumped slightly in relief, her hands still glowing over Kael.

"We... we actually did it..."

Kael let out a weak laugh.

"No," he said. "He did."

Their eyes shifted upward.

To the sky.

To the helicopter hovering above.

Marcus lowered the launcher and finally relaxed his shoulders.

"...Pilot, bring us down," he said. "Same area. Keep it steady."

"Copy, descending."

The helicopter tilted slightly, then began its slow approach toward the ruined street. Smoke still drifted through the air, but the flames had died down enough to make a landing possible.

Below, Seraphine and the others stepped back, giving space.

The rotors roared as the aircraft touched down, kicking up ash and dust across the broken ground. The side door slid open, and Marcus stepped out, boots hitting the scorched stone with a solid thud.

Up close—

The damage felt heavier.

The heat still lingered.

The smell of burned flesh and rubble sat thick in the air.

Marcus walked toward them without rushing, his gaze briefly passing over the dragon’s corpse before settling on the group.

"...You all good?" he asked.

Seraphine nodded once.

"We’re standing," she said. "Barely."

Selene, however, crossed her arms and looked at him with a small pout.

"...You know," she said, "you could’ve done that earlier."

Marcus raised an eyebrow.

"Done what?"

She gestured toward the dragon.

"That," she said. "The flying explosive thing."

Marcus let out a small breath.

"I was observing," he replied simply. "I needed to see how it moved, how it reacted, and how tough it actually was."

Selene didn’t look convinced.

"...So we were your test subjects?"

Marcus shrugged.

"You handled it," he said. "And now I know what works."

Kael let out a weak chuckle from where he lay.

"...You’re annoying," he muttered.

Liora shot Marcus a look, though it wasn’t hostile—just tired.

"...He almost died."

Marcus’s expression shifted slightly as he glanced down at Kael.

"...Yeah," he said. "But he didn’t."

He crouched slightly, studying Kael’s condition for a second.

"...You’ll live," he added. "Your healer’s good."

Liora blinked at that, then looked down at her hands.

"...I did what I could..."

Seraphine stepped closer, her gaze steady on Marcus.

"...Those weren’t spells," she said. "What you used."

Marcus stood up again.

"No," he said. "They weren’t."

A brief silence followed.

Selene looked between the dragon and Marcus again.

"...Then what are they?"

Marcus glanced at the ruined body one more time.

"...Something that kills things like that," he said.

Kael let out another weak laugh.

"...Yeah," he muttered. "I noticed."

Seraphine exhaled quietly, her grip on the bow loosening just a bit.

"...Regardless," she said, "you fulfilled your role."

Marcus nodded once.

"So did you," he replied and added. "So, what do we do now? We killed the Red Dragon, so when will I be paid?"

Seraphine didn’t seem offended by the question.

If anything, she expected it.

"...Straight to the point," she said.

Marcus gave a small shrug.

"That’s business."

Selene let out a quiet sigh, still catching her breath.

"...We almost died and that’s the first thing you ask?"

Marcus glanced at her.

"We didn’t come here for free," he said. "You knew that."

She didn’t argue after that.

Because he wasn’t wrong.

Seraphine stepped forward slightly.

"The reward is issued by the Kingdom of Felsis," she said. "We need confirmation of the kill first."

Marcus looked at the dragon.

"...That thing isn’t getting back up."

"No," Seraphine agreed. "But protocol is still protocol. The guild and the local authority will verify it."

Kael groaned slightly from the ground.

"...So we have to wait?"

Liora shook her head.

"Not here," she said. "You need treatment first."

Marcus nodded once.

"Yeah," he said. "We’re not staying in a burned-out city with a corpse that big."

He looked back toward the helicopter.

"We move to a safer area. My ride’s still good."

Selene glanced at the aircraft, then back at him.

"...We’re using that again?"

Marcus raised an eyebrow.

"You walked here?"

She frowned slightly.

"...Fair."

Seraphine looked back at the dragon, then at Marcus.

"...Before we leave, we secure proof."

Marcus crossed his arms.

"What kind?"

She pointed toward the corpse.

"A core, scales, or a confirmed fatal wound," she said. "Something that can’t be disputed."

Marcus thought for a second.

Then nodded.

"Alright," he said. "Make it quick."
