Isekai Adventure in the Dimensional Cube

On the day of the Monster Festival, the carnivorous flower monsters caused a commotion in the streets, destroying numerous stalls, pavements, and buildings. Although there were no casualties, the property damage was indeed substantial.

But after more than a month had passed, most of the damage had been repaired, except for the large hole blasted open by Reiger's magic, which remained unfilled and barely tidied.

Why?

Because the hole was simply too deep.

The scorching sun from the daytime sky slanted down into this large hole, only illuminating less than half of its depth, with the lower part shrouded in complete darkness.

At the bottom of the deep hole, rubble and debris were scattered everywhere, forming small ruins, creating a scene akin to an abandoned battlefield.

Trickles of water seeped from the surrounding rock walls, flowing at the bottom of the deep hole, forming small streams.

To clean up and fill such a ruin truly required significant manpower and resources, something not accomplishable in a short period.

Hence, the guild prioritized repairing the district, leaving this large pit unattended. Only once the district repairs were complete would they take action here. It's unknown how long it would take to completely fill such a large pit.

Faced with such a large pit, not to mention the unaccompanied construction workers, even ordinary adventurers couldn't operate here.

Therefore, when it comes time to repair this large hole, the guild will certainly have to commission the commercial clans specializing in civil engineering to dispatch professionals with blessings to start the work; otherwise, just accessing the area would be a problem.

Finn was obviously well aware of this.

So, he left most of the lower-level members on the surface to carry out the investigation in the city, while only high-ranking members above Lv.4 were assigned to investigate in the hole, including several executives sent by him.

Thus, at a certain moment, several figures suddenly leapt from the top of the hole leading to the daytime sky, jumping into the hole and finally landed at the bottom after hanging in the air for a while.

"Wow, it's really deep."

Theona, carrying her large double blades, glanced at the seemingly distant hole entrance and exclaimed.

"It really is quite deep." Theone couldn't help but glance at a certain someone beside her and said snappily, "You actually collapsed it to this extent, it's fortunate the guild didn't make us pay. Otherwise, our clan might have gone bankrupt before the expedition, right?"

"...I really didn't mean to." Reiger was silent for a long time before quietly saying, "To tell you the truth, I was already being restrained."

This was not an excuse.

It should be noted that back then, Reiger was only demonstrating his capabilities as he just reached Lv.5. Who would have thought that a single-target magic, the [Arc-shaped Beam], could cause such massive destruction?

Of course, that was Reiger's naiveté.

Though at that time he indeed only exhibited capabilities as he just reached Lv.5, there were certain things he didn't have back then upon first reaching Lv.5.

Such as the development ability "Magic Chant".

For instance, the skill "[Sun Wheel Pioneer]".

Amplified and strengthened by development abilities and skills, even if he only showcased the powers of someone at Lv.5, the potency of his magic couldn't be compared to the past.

Such was the Reiger that naturally became subject to Theone's mockery.

"Equivalent to a Lv.7 magic guide's firepower, and you're telling me this is being restrained?"

Theone only wanted to chuckle, leaving Reiger speechless.

"Compared to Reiger, even Rephia seems normal now." Theona further sighed, "Let's see how that dumb wolf can still call Rephia a magic power idiot after that."

"Ah ha... ah hahaha..."

Rephia, holding her magic wand and standing aside, was accidentally caught up in the conversation and could only awkwardly laugh.

Only Ais, looking at this deep pit, uttered a heartfelt thought.

"Really, amazing."

...No, the problem isn't about being amazing or not, right?

Those present silently retorted in their minds.

Reiger dared not continue the topic and could only scan the surroundings while observing his group members.

The main personnel descending to the pit's bottom to investigate included himself, Ais, Theona, Theone, Rephia, and several Lv.4 members from the clan's second military group.

Finn, Revilia, and Grace were managing the overall situation on the surface, communicating with guild staff and the Ganisa Clan, and gathering information, while Bert, Raul, and Angel led the lower-ranked members of the clan to investigate around the city.

Incidentally, Loki was also present, though this elusive trickster of a god had slipped away to who knows where again.

"Alright, enough chatter, let's start the investigation."

Reiger just said this, prompting nods from everyone.

With that, everyone dispersed together, roaming within the pit.

The pit's bottom was very dark, rendering almost nothing visible. If it weren't for the individuals present being at least Lv.4, with vision and senses far exceeding ordinary humans, they wouldn't have been able to wander here freely.

Under these circumstances, just as Reiger was about to activate the "Perpetual Light" magic to illuminate the surroundings, Theona, Theone, and others took out magical stone lamps, letting the light emitted from them slightly brighten the vicinity.

"Alright."

Reiger muttered a few words, letting his gaze roam the surroundings once more.

A transparent glimmer flickered in his eyes, fully activating the translucent world.

The Lokis' clan's objective for this endeavor was to investigate the carnivorous flower monsters that disrupted the Monster Festival, tracking their movement paths and further uncovering the traces of those controlling them from behind the scenes.

On the day of the Monster Festival, the carnivorous flower monsters emerged from underground, leading Finn to highly suspect that there were passages underground in Orario serving the movement of these monsters.

The passage could possibly have been secretly excavated, or it might be part of the underground sewers of Orario.

The task of Reiger and others was to find out the passages these man-eating flower monsters used to move, and trace them back to the enemy behind the scenes.

This task wasn't difficult.

At least, for Reiger who knew the original story and even the enemy's stronghold, it was indeed so.

"————"

In the state of activating the transparent world, Reiger's sensory abilities were greatly amplified, and his mind gradually became clear.

In his eyes, the entire world was transparent. The ruins, rubble, stones, and even rock walls could no longer block his sight, easily being seen through.

Soon, Reiger discovered an anomaly.

"Is it over here?"

The transparent luster in his eyes dimmed, and Reiger walked straight to a corner of the rock wall.

The soil here was looser compared to other places, and the rock wall seemed relatively thin. By placing an ear against it, faint sounds of flowing water could be heard.

"[Disassemble]."

Reiger placed one hand on the rock wall and activated the disintegration magic.

In an instant, a crimson wave appeared, causing the rock wall touched by the wave to disintegrate like ash, revealing the sight inside.

Upon closer inspection, it turned out to be a tubular tunnel constructed from stone.

The tunnel was about six meters wide, with a stream running through the center and paths on either side for people to traverse, with branching waterways leading to different places, causing the sound of water to continuously echo here.

Without a doubt, this was the sewer system beneath Orario.

Reiger walked into this waterway and easily found long dragging marks within it.

Judging from the size and shape of the tracks, it was obviously left by some huge serpentine creatures passing through here, and more than one.

"[Route Detection]."

Reiger activated an intelligence-type magic that could detect routes and positions, making a game-like map unfold in his mind, showing the various sewer routes and the general directions of the city.

Then, having pinpointed a certain direction, Reiger moved without hesitation along one of the sewer routes, gradually moving away from the deep pit.

This scene went unnoticed by the clan members seriously investigating the scene.

No, two people did notice.

"Reiger?"

Ais, who was attempting to move a small ruin, happened to see Reiger entering the sewer and paused slightly before immediately following him.

"Mr. Reiger?"

Rephia, who had been watching Reiger all along, also caught a glimpse of this scene and, after hesitating for a while, hurriedly followed as well.

"Why are you here?"

Hearing the distinct echo of footsteps in the sewer, Reiger could not help but stop in his tracks and, slightly stunned, looked at the two girls who had caught up.

"I just subconsciously..."

Rephia, clutching her magic wand, said somewhat embarrassed.

"Did you discover something?"

Ais succinctly inquired.

Seeing this, Reiger stopped questioning further.

"Sort of." Reiger pointed to the still-visible dragging marks in the waterway and said, "These are proof that man-eating flowers have been crawling through here for some time."

"The captain guessed correctly. The mastermind utilized the underground sewer system of Orario to release the man-eating flowers, which is why they emerged from the underground and attacked us on the surface."

"Thus, by following these tracks, we can find out where the man-eating flowers crawled to East Street."

"I'm getting ready to head over now."

On hearing this, the two girls spoke bluntly.

"I'll go with you."

"I'll go too!"

Ais's voice was decisive while Rephia sounded hurried, forming a stark contrast.

"Alright." Reiger did not object either and said, "Although spreading out to search would be more efficient, if you want to follow, then come along."

Saying so, Reiger led the way forward, visibly preparing to guide them.

He had no choice, as his goal on this trip was to lead the clan members to find the enemy's stronghold, so naturally he wouldn't let others lead the way.

Ais and Rephia, seeing Reiger move quickly, despite being somewhat surprised, soon followed closely.

The three-person group then diverged from the area where the clan's companions were gathered, heading in a certain direction of Orario along an underground sewer.
