They didn't need Fron to explain in detail.
Anyone who could take part in this expedition was already the in the know, carefully selected from countless adventurers.
With just one glance, they immediately matched what they saw with the information in their memories.
The magic ritual said to have sealed the evil dragon Nidhogg, a ritual close to divine power that could only be unleashed when six Great Spirits, known as Avatars of the Gods, joined forces, the "Ring Spell."
Now, this terrifying thing had been replicated, and was displayed right before their eyes.
Before seeing the real thing, even if Finn and the others emphasized it again and again, most adventurers didn't take it seriously.
For them... this mission was simply about defeating the enemy, just like always.
As for the claims about the entire Orario and the surrounding lands being blown away upon activation, they completely dismissed it.
Until this very moment, right here.
Just looking at that band of light was enough to make them feel the bone-deep fear contained within it. No matter how much they wanted to deny it, they were forced to face the cruel truth.
The intel from the higher-ups… was real.
Everyone lowered their heads to look beneath their feet, then stiffly raised their eyes, numb, staring at Fron's back. They opened their mouths but found no words.
"Th-That kind of terrifying thing… it actually exists? I always thought it was just something the 'Braver' made up to scare us."
One adventurer stammered out his true feelings, fear slowly rising in his eyes.
Just thinking about such a thing lying beneath Orario would make anyone's scalp tingle on the spot.
The change in their mentality was naturally noticed by Fron.
Expression unchanged, he lifted his head, completely ignoring the glowing band beneath his feet.
After thinking for a moment, Anakitty made a suggestion.
"This light band… is it the 'foundation' meant to destroy the Labyrinth City Orario? Then… as long as we destroy this 'magic circle'..."
"It's useless, Anakitty. Cutting off the 'mana' flow by attacking this won't work. What passes through this floor is only the surface layer. It's not just the floor, the entire floor structure surrounding the Dungeon is itself one enormous magic circle."
Before Fron could speak, Amid shook her head, sighing with irritation.
As someone who possessed "Mystery," Amid's magic-related knowledge was in no way inferior to a professional mage's , in fact, due to her specialization, she surpassed them.
She scraped away part of the floor with the ornate staff she held. The green flesh beneath regenerated instantly, covering the cut at a speed visible to the naked eye.
The spot she attacked returned to normal as if nothing had happened, as though it were casually using abundant "mana" , the absorbed "nutrients" from the Dionysus Familia, the adventurers, monsters, and the Evilus remnants.
"Obviously, this floor is completely different from the other levels. The enemy must've prepared this long ago, quietly remodelling everything right under the noses of the Evilus remnants."
"The mana particles flooding the air are way too vicious... When I first entered, even I felt slightly dizzy."
Amid's expression hardened.
As a healer, insufficient mana was always her biggest weakness, not because her abilities were lacking, but because her magic was simply wide-ranged, and continuous.
Amid's full-party healing magic was continuous output, constantly consuming mana.
Yet even she admitted to dizziness, proving just how absurdly dense the mana in this floor truly was.
With her slender brows knitted, Amid spoke with clear displeasure.
If one looked closely, the rear-line mages in the unit looked even worse than she did.
"Hah, Amid is right. If I had to describe it… this fourteenth floor is a super 'Mana pot' capable of wiping out the entire Orario and its surroundings. You can imagine what would happen if even one unexpected thing occurred here, right?"
Fron's cold, emotionless words poured into everyone's ears.
It was like dousing cold water onto anyone who had the slightest thought of doing something reckless or stupid.
His words made all the adventurers freeze, forgetting the situation and stopping their movements… even forgetting to speak.
This place was the powder keg, the soon-to-explode "arsenal" , that could blow away Orario overhead.
A deadly minefield.
Understanding Fron's implied warning, all the adventurers swallowed hard.
"There's singing…" Anakitty whispered softly.
Everyone looked up toward the depths of the passage ahead.
A "song" echoed, delicate and fragile, like that of a young girl.
"So this is the legendary chant of a Spirit..."
"Everyone, remember why we came here: to defeat the 'Fallen Spirit.' Once we succeed, this ritual will naturally stop running. So don't think about anything else, just give it your all, and leave no regrets!"
Fron was absolutely not suited for boosting morale, but he still said it.
"Move!" For him, leading from the front, setting an example, was far more important than fancy words.
....
At the same time, the squads entering from the surface through the other places also heard that song.
"So this is the song the leaders mentioned? Hearing is believing… Even as a warrior with no magic, I can tell how spine-chilling this feeling is. Unbelievable!"
"Such a scary voice… it's disgusting."
Compared to the warriors, the mages in the group were far more sensitive.
The chant continuing even now, its sheer weight surpassed even a super-long incantation, proved that an unimaginably massive "magic" was being prepared here.
It was eerie yet beautiful, hideous yet pure, truly fitting to be called the demonic "Song of Corruption" that brings ruin.
This chilling "song" belonged neither to humans nor to monsters. To everyone, it felt like something even more heretical than dungeon monsters, a true "aberration among aberrations."
