"... thump! Well, you could have done this, too. That's it or what?"

After [decomposing] the ground and descending to the basement of the castle, Chandler nodded several times as if he were interested.

For the time being, destroy the ground - [repair] the ceiling you see from here to block the hole so that the AGART RAM people on the ground don't know about the intrusion.

Then I took a quick visual look around the location we broke into.

We don't know what enemy power looks like around us, and we don't even see anything moving around.

"Is it an underground passage? In that case, the ceiling and the road width seem to be quite large...."

Sakura is also attempting to analyze the location while keeping an eye on the surroundings.

Without relying on the "right eye", it is obvious that this is the type of passage.

A gentle slope connecting the direction of the castle of the Ark and the other side.

As Sakura said, the ceilings dotted with magic lighting are considerably higher and the roads wider than that.

While Sakura and I turned our attention to the ceiling, Garnett gazed towards our feet.

"... it's more like a supply corridor than a communication corridor. You're not supposed to walk in or out, are you?

Beyond Garnet's gaze was the so-called line (...) path (...).

The feet were dim, making it difficult to understand, but there were two tracks in the middle of the wide passage, and we were standing in the space between them and the wall.

Perhaps AGART RUM's guards are not deployed here because they have taken control of the exit side of the corridor.

If this underground corridor is a main road connecting a place on the ground to the basement of the castle, it is not surprising that there is no need to place security inside the corridor if one of the places is held down.

"I see. He's like a mine trolley."

Chandler casually tried to reach out to the tracks, so I let him cross my arm in front of me to stop it.

"Wait. It looks like magic is flowing in there. You shouldn't touch it easily."

"Hmm? What kind of trolley is that?"

"It seems that ancient magical civilizations had such vehicles. Large passenger cars run on the railroad. Maybe it's a substitute for bringing in supplies."

What I've seen before - it's just a reproduction of the world of memory - was that the leading vehicle was responsible for the accumulation of magic and the generation of power.

Apparently, however, there is also a type that travels while being continuously supplied with magic from the outside, and the latter is used in this underground passage.

"This track is still raw (...) and (...) ru (...). Don't step inside the track, tell the end of the road to get into the castle."

"I've been doing my magic all along. It could mean that the vehicle is coming in from behind."

Garnett jokes and laughs.

But the content of the statement is not a joke.

I heeded the "right eye" and heightened my vigilance, then resumed moving towards the back of the aisle.

"The tracks are still alive. That means there's something (...) ahead that needs supplies."

"I wonder if you're making something. Or are you renovating the basement?"

"Maybe they're carrying supplies for maintenance, not manufacturing."

Chandler raised his eyebrows and murmured as he kept his voice as low as possible.

"This corridor seems to be going a lot deeper... and it's slowly arcing..."

"Looks like there's a big library down below a certain level."

If you create a straight line to the desired depth, the slope becomes steeper than necessary, so you may be drawing a helix and smoothly adjusting the slope.

On the ground, it would have been possible to loosen the gradient while making the road straight by making the entrance and exit farther away, but this was not the case on floating islands with limited land area.

"I'd be glad if you could get me a direct line to the library. Is that too convenient?"

"With your skill, you can [disassemble] and shortcut through walls and ceilings. It's not gonna be a big time loss, is it?"

"If it comes to trouble, I'll do it again. Whether a demon or a snake comes out....."

In the end, the underground passage draws a gentle arc of a circumference in a helix and immediately hits the deepest point.

It's a dead end, but it's not just a wall.

However, the door is too large, and there is a vertical groove that opens from the center to the left and right, but I don't think it is assumed to be opened and closed manually.

"Come on, Luke. Can you see it?

"At least there's no sign of magic beyond him. The only way to open and close the wall... is from the inside."

Point your hand against the wall to activate Analytics and compare the information obtained from the two abilities.

The wall appears to have been constructed to open and close by massive ingenuity, as expected, but the operating panel is only provided on the other side of the wall.

As the truck with the supplies comes down, it seems to be operating the opening and closing from the other side to let it pass.

I can't help it. It's a breakthrough.

I quickly switched the effect of the skill to Disassembly and punched a hole in the wall to allow humans to pass through.

At the tip of the hole was a hall like a supply depot.

The track is the end of the hall, surrounded by metal boxes of all sizes and sizes, but so far, the "right eye" has not captured anything suspicious.

However, as long as it is limited to this hall.

"... hey, Luke. What's the matter? Something happened."

Garnett feels the change in my expression and peeks into my face with a mix of anxiety and vigilance.

"There's nothing here... but deeper... there's something in the neighborhood... what is this... a lot of tiny magic in regular line... damn, I can't read it from here..."

"Then I'll have to go. Normally, we avoid suspicious monkeys, but we're explorers now."

I also nod to Garnett's opinion.

I was careful not to be found on the ground by my enemies, but this is no longer on the grounds of the Ark Castle.

Uncovering the secrets hidden there is the role we have been given.
