I Died and Became a Noble's Heir

Chapter 578: Floor 4 - Hollow of the Sunless Tide [Golden Ticket Chapter Bonus]

The technique was crude compared to actual vision, and maintaining constant mana output drained his mana steadily.

But it worked, providing a functional navigation method in an environment designed to eliminate all normal sensory input.

Minutes passed.

Jack couldn’t track time accurately without external cues, but his internal sense could guess it had been fifteen minutes.

The mana echolocation grew more refined as he practiced, his awareness learning to interpret the feedback patterns with increasing precision.

Then he detected it: a gap in the feedback approximately forty meters ahead and slightly to the left.

Opening where mana passed through rather than bouncing back.

A passage to the next floor.

Jack adjusted his trajectory, moving toward the gap with careful steps that tested the ground before committing weight.

The mana pulses confirmed the path remained clear, no obstacles between his position and the exit.

His hand eventually contacted the stone archway that his magical feedback had indicated, physical confirmation validating the navigation technique.

Relief flooded through him despite the tactical part of his mind recognizing he’d solved the challenge exactly as designed, forced to develop a new perception method when normal senses became useless.

He stepped through into the fourth floor.

Sensory input returned with a jarring that made him blink against light, seeming blinding after the complete void.

Sound rushed back: his breathing, Father Caelen’s footsteps, and ambient noise from the inverted forest.

Temperature registered again, cool air against skin that had been unable to perceive such variation moments ago.

Father Caelen emerged from the archway seconds later, the old priest’s expression showing profound relief at being able to see and hear again.

"That was deeply unpleasant," he stated. "Forty years of dungeon experience and I’ve never encountered complete sensory deprivation like that. How did you navigate?"

"Mana echolocation," Jack replied, his yellow and orange eyes already scanning the fourth floor’s environment.

’Extended magical energy outward and tracked feedback when it bounced off surfaces. Crude compared to actual vision, but functional for basic navigation."

Then his tactical assessment froze as he processed what the fourth floor actually contained, and everything else became secondary to the impossible sight before him.

Bodies.

Hundreds of them, scattered across the inverted landscape.

But these weren’t Elysium natives wearing fantasy armor or carrying enchanted weapons.

These were humans from Earth.

Jack recognized it immediately despite the advanced decomposition. The equipment that wouldn’t exist in a world governed by magic and martial arts.

Modern military gear.

Tactical vests bearing pouches designed for magazine storage, helmets with mounting points for night vision devices, boots constructed from synthetic materials that didn’t exist in Elysium’s medieval-adjacent civilization.

And the weapons.

Assault rifles scattered everywhere, M4 variants with rail systems and optical sights, AK-47’s in various states of disrepair, what looked like SCAR-H with heavy barrels designed for sustained fire.

Sidearms that could have been Glocks or Berettas, their polymer frames still intact despite their wielders having decomposed to skeletal remains.

But the equipment bore modifications Jack didn’t recognize, futuristic additions from technological advancement beyond what Earth had achieved in his original timeline.

Power sources integrated into weapon systems, attachment points for devices whose purpose he couldn’t identify, armor materials that looked more advanced than anything contemporary military had fielded.

Jack moved among the corpses slowly, his mind cataloging details with growing confusion mixed with something approaching grief.

These were his people. Humans from Earth, soldiers who’d somehow ended up in Elysium dungeon carrying weapons that operated on principles this world shouldn’t understand.

The bodies were positioned defensively, creating a perimeter that coordinated the last stand against overwhelming assault.

Spent shell casings littered the ground. Thousands of rounds were fired in what must have been a desperate attempt to hold position against enemies that had ultimately overwhelmed them.

But there were no enemy corpses.

No indication of what they’d been fighting or remains of whatever had killed hundreds of well-armed troops without leaving any fallen attackers behind.

Jack knelt beside one corpse whose armor bore insignia he didn’t recognize.

An eagle design with stars and technical symbols.

A military unit designation from a timeline beyond his original death.

The skeleton’s hand still gripped an assault rifle, finger bones positioned as if the soldier had been firing when death claimed them.

Father Caelen examined the nearby body with professional curiosity, his weathered features showing interest rather than recognition.

"I’ve never seen equipment like this. The construction is completely foreign, not dwarven metalwork, not elven enchantment, not any crafting tradition I’m familiar with throughout Elysium." He gestured at the scattered weapons. "What are these devices?"

"Guns," Jack replied, his voice carrying the weight of knowledge Father Caelen couldn’t share. "They use chemical propellants to launch metal bullets at high velocity. No magic required, just physics and engineering that have spent centuries perfecting."

He picked up one of the assault rifles carefully, the weapon’s weight familiar despite years since he’d handled such technology.

The rifle was an M4 variant, probably chambered in 5.56mm based on magazine dimensions. But modifications had been added.

Power cell integrated into the handguard, targeting system more advanced than anything he recognized, utilizing materials and manufacturing capabilities beyond current capabilities.

’These soldiers are from Earth,’ Jack continued, setting the weapon down with care that bordered on reverent. ’My original world. Somehow they ended up here in Elysium, in this specific dungeon, fighting something that killed them all without leaving any enemy bodies behind.’

Father Caelen’s expression shifted into understanding mixed with concern. "An invasion force?"

"Maybe," Jack replied, his tactical mind racing through implications he didn’t want to accept.

"But that raises questions I can’t answer."

’Earth doesn’t have System access, doesn’t have magic, operates on completely different fundamental principles. An organized military expedition to reach Elysium suggests a connection between worlds that shouldn’t exist.’

He stood slowly, surveying the graveyard with eyes that had seen too much death across two lifetimes.

Hundreds of humans, soldiers who’d trained, deployed, fought in a world that shouldn’t have been able to reach this one.

Their bodies lay scattered across the inverted dungeon floor, a memorial to a failed invasion or a desperate expedition whose purpose had died with them.

The silver veins on Jack’s right arm pulsed with a steady rhythm, their glow seeming slightly brighter against the backdrop of Earth’s military equipment and decomposed human remains.

And now he stood in a dungeon that connected his original world to his current existence, surrounded by evidence that Earth and Elysium weren’t as separate as he’d believed.

The exit archway stood at the graveyard’s far end, a stone passage leading upward toward the fifth floor, where a new floor awaited him.

But Jack remained motionless for several more seconds, tactical assessment trying to process what hundreds of dead Earth soldiers meant for a relationship between worlds.

For his own existence spanning both realities, for whatever cosmic forces had arranged his reincarnation into a System-governed fantasy world.

No answers presented themselves.

Just more questions, and the growing certainty that clearing this dungeon would reveal truths he might not want to face.

"We should continue," Father Caelen said quietly, his tone carrying understanding that Jack needed a moment to process.

Jack nodded once, forcing his tactical assessment back into focus. The dead soldiers deserved an investigation.

Answers about how they’d ended up here and what they’d been fighting.
