Isekai Adventure in the Dimensional Cube

"What the...!"

Seeing a person appear at the front of the passage, Bert, Theona, and Theone, who were running at the front, all gasped.

"How can there be someone here...!?"

Led by Chun, the supporters who hadn't participated much in the battle were equally shocked, and Raul even shouted out in disbelief.

This is the 52nd floor of the underground city, not only starting point of the "Dragon Pot" but also the forefront of the dungeon conquest.

Only those who can reach such a deep level, even if you search all of Orario, are probably only the Loki Familia and the Freyja Clan.

The deepest floor the Loki Familia has reached is the 58th floor, as is the Freyja Clan.

Apart from these two strongest factions of the city, there's almost no one else who can come to this level.

And now, there's someone blocking the Loki Familia, how could everyone not be astonished, not be shaken?

Only Ais, upon seeing that person, had her pupils suddenly contract.

"Monster..."

Yes.

The one who came was no other than the hybrid of human and monster whom Ais encountered in the food storeroom on the 24th floor — the monster.

This person, cloaked in white robe and wearing a white bone mask, was undoubtedly the white-cloaked man.

"Here we go."

The white-cloaked man's neurotic voice sounded, as if mocking, as if excited, opening his arms widely to the oncoming crowd.

"Very well, I have come to pick you up, Alya."

Upon hearing the call from the white-cloaked man, Ais bit her lip and gripped her sword even tighter.

"Alya?"

Everyone looked confused, not knowing who the white-cloaked man was calling.

Only Finn, Revilia, and Grace finally changed their expressions upon hearing this name.

"Come out!"

The white-cloaked man, without paying any attention to the group, continued to shout loudly, which summoned shadows from behind him.

Lo and behold, they were worms.

An endless army of worms appeared, not only flooding the wide passage but also arranging themselves in a disciplined formation, then collectively raising their upper bodies, opening their mouths, and spitting out a large amount of corrosive liquid.

"Oh no!"

"What is that...!?"

"Captain!"

Bert and Theona, at the front, had drastic changes in their expressions, while Theone desperately shouted Finn's name.

There was no other way.

The swarming worm monsters formed a formation and simultaneously spewed out a large amount of corrosive liquid, causing it to form a torrent that became a flood of sewage, like a mudslide, rushing through the rocky passageway and flowing toward the group.

That was no longer liquid stream, but a tidal wave.

The torrent of corrosive liquid filled the entire rocky corridor, dissolving the walls, ceiling, and floor, carrying a sizzling corrosive sound, pungent stench, and billowing black smoke, preparing to mercilessly engulf the group of insignificant adventurers.

"Quick, retreat!"

Chun finally shouted anxiously.

"No!" Finn quickly and decidedly rejected the suggestion, saying urgently, "Retreating will only make us targets for the Cannon Dragon! We cannot retreat! We can't even stop our advance!"

Just as if to prove Finn's point, the ground started to shake.

"Boom!!!"

Behind the group, the ground was blasted upward again, and crimson flames erupted from below, reaching the ceiling, even incinerating the flying dragons attacking the rear of the expedition party.

"Tch!"

Grace, who was dealing with the flying dragons, was accidentally affected by the blast and retreated back into the team with his body aflame, covered in scorch marks.

Seeing this, everyone's face turned pale.

In front of them was the corrosive torrent that melted the labyrinth itself and covered the entire passage, impossible to defend against or evade.

Behind them was the ultra-long-range bombardment that could destroy the dungeon floor in one blast, reaching several floors.

The walls on either side prevented any change of route.

They couldn't retreat, couldn't stop, and could only rush towards the torrent of corrosive liquid, caught in a pincer attack.

A deadlock.

This desperate thought flashed simultaneously in everyone's mind.

Ais was even preparing to step forward, using her wind-embroidered body to crash into the corrosive liquid to pave a way for the others.

But could that work?

Even if Ais was wrapped in superior wind force, a pebble thrown into the torrent would still face only one outcome - being swept away.

At that time, Ais could protect herself at most, but not others.

Thinking of this, a trace of anxiety appeared on Ais's usually emotionless face.

Until—

"[Omen of the End, Snow White.]"

Bearing the not yet dissipated magic array, Reiger dashed out from the team.

"Reiger!"

"Mr. Reiger!"

"Reiger, kid!"

The crowd couldn't help but shout.

Reiger turned a deaf ear and completed the magic chant at an astonishing speed.

"[At the moment of dusk, let the wild winds rise. Sealed light, frozen earth. Sweeping snowstorm, triple winter—my name is Alf.]"

In the next second, three blizzards appeared from the magic array beneath Reiger's feet.

"[Frenzied Fimbul Winter]!"

The blizzard surged forward, colliding with the oncoming corrosive liquid stream.

"Crack crack crack—"

The moment the corrosive liquid touched the blizzard, it was instantly frozen by the intensely low temperature of Absolute Zero, gradually transforming into an ice block, becoming a long glacier.

"[Flame Volt]!"

Immediately, Reiger raised his hand and shot out a lightning-like Flame Thunder, striking the glacier with a thick, pillar-like bolt, causing a massive explosion.

"Boom!"

In the explosion, the pillar-like Flame Thunder shattered the glacier, clearing the huge ice blocks blocking everyone's path.

Fragments of ice rained down like a torrential storm, but the group pressed on without losing speed, scrambling to dodge the ice.

"Well done!"

Finn couldn't help but loudly praise Reiger.

Thanks to Reiger, the path was reopened, and the white-robed man leading the worm army reappeared in sight, coming into everyone's view.

"It's you again...!"

The white-robed man, seeing Reiger who had dissolved the army of worm monsters' collective corrosive liquid attack, seemed to have his face twisted under the white bone helmet.

Seeing this, Reiger's expression turned cold. He no longer suppressed his speed, and with a whoosh, shot towards the white-robed man like a racing wind.

"Swish!"

Accompanied by the chilly sound of a sword singing, Reiger swung his sword at the white-robed man, slicing through the space with a cold arc aimed at the man's throat.

"Wha...!"

This time, it was the white-robed man's turn to gasp.

Just because Reiger's sword speed was much faster than the speed shown a few days ago in the food warehouse on the 24th floor, it could even be said to be a different level.

That was to be expected.

At that time, Reiger's abilities were still at the initial level of Lv.5, but now they had been unleashed to the Lv.5 extreme.

One had just stepped onto the starting point, while the other had reached the end point. How could they be the same?

Coupled with the A-rank "Light Armor" ability and the dual high-level enhancements of "Agility" from the defensive magic [Lamu] just cast, it would be strange if Reiger's speed was still the same as before.

Unashamedly put, Reiger, at his current speed, could compete for the title of "City's Fastest" against [Goddess's Chariot].

This level of extreme speed led to the white-robed man's misjudgment, still thinking Reiger was the bothersome adventurer from last time, and reacting a bit late.

By the time the white-robed man reacted and tried to evade, he only had time to retreat half a step.

And it was this half step that avoided the fate of him being directly beheaded.

"Psst!"

When the dark crystal longsword sliced across the white-robed man's throat, its tip touched the opponent's throat, slicing halfway through his neck.

"Urgh... Gagagaaahhh...!"

The white-robed man staggered back, clutching his throat as if struck by lightning, spilling a large amount of blood and letting out a hoarse, screeching scream.

"Wooowoooooohh—!"

At the sight of this, the worm monsters behind the white-robed man screamed hoarsely and sprayed corrosive liquid at Reiger.

"Da—da—da—da—"

Having succeeded with one strike, Reiger didn't linger, tapping his toes on the ground repeatedly, darting back and forth like an illusion, dodging the incoming corrosive liquid one by one.

By this time, the rest of the expedition team had arrived.

"Revilia!"

Finn called out to the elf royalty.

"[High-level Victory Sword]!"

Revilia, without a second thought, directly released the wide-area annihilation magic she had just completed and kept on standby.

"Boom!!!"

The magic array expanded to cover the entire ground, and after a rumble, numerous pillars of flame erupted.

Each flame column was comparable to the [Flame Volt] just released by Reiger, with its thick, pillar-like fiery force.

Numerous pillars of flame burst forth, scorching the ground, blackening the walls, and incinerating all worm monsters within the magic array's range and the flying dragon monsters approaching from the rear, drawing countless screams.

Under such wide-area bombardment, the group of drakes at the rear was directly eradicated, and the worm monsters at the front were scattered, finally clearing a path ahead for the group and no longer being attacked from both sides.

"Quick! Go ahead before more come flying!"

With Finn's command, everyone immediately quickened their pace, swiftly charging through the scattered army of worm monsters, stepping over the scorched ground, heading towards the end of the passage.

"No... don't... run...!"

The white-robed man with a sliced throat angrily reached out towards Ais.

Unfortunately...

"Are you the only one coming?"

Just like how the white-robed man had blocked their path earlier, now it was Reiger standing in front of the white-robed man.

"Then that might not be enough to prevent me."

Reiger's calm words drove the white-robed man mad with hatred.

"Reiger... Brilliant...!"

This meddlesome man, it seems he should've been dealt with first.
