Reborn as an Extra Chapter 611: S-rank Dungeon, A Forgotten Nation. Part-6.

Previously on Reborn as an Extra...
Lia critiques James's unconventional, brute-force swordsmanship during their journey, dismissing it in favor of learning from Rio, which leaves James sulking as he guides her across a perilous lava pool teeming with monstrous creatures. Lia flies using her fairy wings, which purify the toxic air, while observing the diverse lava ecosystem and reflecting on her extensive knowledge of monster physiology. Upon reaching the secured entrance, a gargoyle guardian recognizes James, granting access to the private S-rank dungeon 'A Forgotten Nation,' which uniquely adapts its challenges to the entrant's personal traits, promising Lia immense growth under her father's proud introduction.

[Somehow, I sense that I'm familiar with this dungeon, yet oddly, the details just escape my memory...]

[That's truly peculiar...]

Lia felt astonishment that Kai, renowned for his excellent recall and as a mighty divine spirit, had let something slip his mind.

’It appears my father has ventured into this dungeon on numerous occasions, and he's still breathing. So, that suggests it's conquerable, doesn't it?’

[Hmm... put it this way... it's that for whatever reason, I can't properly assess this dungeon... normally, you'd detect mana waves or shifts in elemental concentration...]

[Those elements aid in gauging a dungeon's danger level and tier... yet this one exhibits intensely powerful spatial waves... they're so intense that without your father shielding them...]

[You'd have been hurled away the instant you stepped into this chamber...]

’He's shielding me from the spatial waves?... Why didn't my keen spiritual sense pick that up?’

[Uh... he's not shielding it on purpose; it's simply because he's so bulky and robust that trailing behind him naturally places you under his meaty barrier against the threats ahead...]

Those remarks nearly made Lia erupt in laughter, though she restrained herself to avoid upsetting her father.

’I crave a real test; even if this dungeon turns out risky, I must proceed... After all, I'm aiming to hit S-rank this round...’

"It adapts itself based on what a challenger requires... How did the awakener’s association allow you to hold onto such an excellent dungeon exclusively?"

James grinned at the inquiry and responded,

"No one realizes it can truly reshape itself to fit the challenger's demands... I came up with that concept myself, actually..."

"I discovered it first and stepped inside... I'm the only one who's gone in more than once..."

James explained the dungeon's intricacies to Lia in depth, and from his account, it operated under a remarkably distinctive rule set.

Once someone conquers this dungeon, it bars that individual from re-entering alone, but permits access if accompanied by another.

The dungeon then draws on both the original challenger and their companion as benchmarks to reshape itself, crafting a layout that offers sufficient difficulty for the pair!

Put differently, by bringing a fresh companion each time for entry, you can repeatedly take on this dungeon indefinitely!

Over the past decades, James has accomplished this repeatedly with various elite guild members.

Guild members have each entered the dungeon just once, while James has delved in multiple times; hence, he's the sole knower of its transformations. The rest remain oblivious.

Lia now stands as the second individual privy to this dungeon's hidden mechanics, besides James!

The awakener’s association views this dungeon merely as a standard S-rank one that frequently reopens at the identical spot, featuring a refreshed layout each cycle.

Dungeons worldwide come in diverse forms; certain ones manifest singly, vanishing after the boss falls, ejecting all within back to the surface.

Others stay fixed even post-boss defeat, remaining accessible indefinitely for resource extraction like ores and more.

Additional types fade upon boss demise, only to resurface later in the exact spot, reborn with altered interiors, fresh monsters, and a new boss!

The very nature of dungeon gates proves utterly enigmatic, with scientists and scholars pondering their sources for ages, yet their true beginnings and essence elude all certainty.

Consequently, these odd occurrences and manifold emergence patterns remain enigmas to humanity.

This dungeon exemplifies such an unusual display of anomalous behavior.

As a stable fixture, it endures intact even after bosses perish, yet bizarrely, its innards refresh repeatedly with novel bosses, sans the disappearance seen in others.

James, however, has concealed this from the awakener’s association.

The association employs numerous SS-rankers, empowering them to swiftly detect potent dungeon gates emerging across the solar system!

Any A-rank or higher dungeon gate surfacing anywhere in the solar system gets spotted by top SS-rankers within mere moments!

Moreover, legendary artifacts of great power monitor dungeon openings of significant strength within the solar system.

This explains why lesser gates frequently trigger dungeon breaks— their faint spatial waves make detection challenging.

Stronger gates, conversely, seldom lead to breaks, as timely alerts allow clearance before escalation.

Even in break scenarios, ’Forgotten World’ emerges as a singular, peculiar dungeon unfit for such outbursts.

Its spatial waves stay contained, looping around it to form this odd subterranean cavern ring.

Hence, SS-rankers overlook its existence until entry attempts stir its spatial fields!

James accesses it sporadically, so waves leak infrequently, alerting SS-rankers only then!

Yet, with James and his guild claiming this dungeon and site as exclusive territory forever, no outsiders meddle.

As a result, the Silver Shadow guild retains full control of the dungeon!

"Let's head in! A lengthy adventure awaits; no more delays with chatter here..."

Flashing a grin, James took the lead, with Lia soaring alongside as they ventured into the dungeon side by side!
