Fine Wine in a Luminous Cup-Come Fly Away with Me (5K)

"Actually, it's not that difficult. In my original world, I always made CAD adjustments manually, performing precise micro-manipulations on hundreds of thousands or even millions of characters. So, learning a language really isn't that hard."

"... is that so?"

Corone couldn't understand what Yotsuba Mahiro saying, but that didn't stop her from looking at the boy with a hint of admiration in her eyes.

Time ticked by, second by second.

Riku and Corone had already rested, while Schwi followed him around, staying with him in the library of Helruin, the old Elf.

Yotsuba Mahiro continued to peruse the book, and when she needed light, Schwi automatically simulate a light source.

Yotsuba Mahiro got hungry, Schwi stopped to eat with him.

Like a silent companion, without a single complaint.

While Yotsuba Mahiro also gained a lot, learning a rough understanding of the history of the Elf.

The elven race, created by the Kainas, is skilled in magic and takes pride in imitating Kainas's casting of multiple spells.

For example, the above records Nina Kleb, who held the title "Lady of the Bloom," and the former "Lady of the Bloom," a woman named Sink Nielbaren.

She is said to be a genius in magic, the first person in the modern era to master the Eightfold Magic.

However, the description of the relationship with this Nina Kleiber seems somewhat subtle, with many overlaps but also subtle differences.

That's strange.

Yotsuba Mahiro scratched his head.

He did know this Sink Nielbaren; he remembered him as the one who played chess with Riku in the original story, and who commanded the Elf fleet to declare war on Artosh and launch a campaign against the Flügel during the great war.

But who is this Nina Kleiber again?

He really didn't remember it...

Chapter 415 Fine Wine in a Luminous Cup, I Want to Take You Flying (5K)

Just as he was wondering who this Nina Kleb was, Yotsuba Mahiro suddenly felt his clothes being tugged.

Looking up, I saw Schwi staring at the ground not far away, "scanning" it. A blue data stream flashed in her eyes as she calmly said:

"Mahiro... a complex camouflage spell has been cast underground... below... a basement has been discovered."

"Basement?"

"Um."

Schwi loosened his sleeve, and Yotsuba Mahiro got up and walked to the spot the other had pointed to, stomping on it a few times.

You mean this place?

"... Um."

"Emmmm..."

Although the mecha girl said that, judging from the feel underfoot and the echoes, the ground here seemed to be solid.

Furthermore, the "Eidos Eye" is also unable to detect what's below.

There are only two possibilities for this problem to occur.

First, it was this wild Schwi on him.

Secondly, the so-called underground space is buried very deep, or perhaps the complex camouflage spell overshadowed his "Eidos Eye" detection.

"... about two hundred meters below," the Ex-Machina girl replied.

Really...

"Eidos Eye" is starting to become less effective.

The "Alpha Stigma" in Yotsuba Mahiro's pupils reappeared, instantly analyzing and copying Schwi's "Detection," with data streams flashing in her pupils as well.

Sure enough, this time, deep underground, just as Schwi had said, there was a huge underground space at a depth of 200 meters.

"Hey, I never thought that Schwi, whose head is full of lewd nonsense, would be useful sometimes."

"I am not yellow waste... My identification code is Uc207Pr4f57t9, my name is Schwi, and my machine is an analytical entity. I am not yellow waste."

"Okay, okay, Uc207Pr4f57t9."

Yotsuba Mahiro repeated it with a smile, Schwi blinked at him, a hint of indescribable emotion in her pupils.

Meanwhile, Yotsuba Mahiro had already Alpha Stigma and covered the ground with it.

"The Nihility!"

Rumble--

He Decomposition a large hole in the ground, leading directly underground.

Although the Decomposition itself wouldn't cause much of a commotion, the building's structure and its deep underground location still triggered a strong earthquake.

"What's wrong? What's wrong?!"

Corone, who was dozing off, was suddenly awakened by a loud bang, like a thunderclap right next to her ear, or like an earthquake shaking the ground violently.

"It's nothing, I just found a few small things. I need to go downstairs. Corone and Riku, you can continue sleeping upstairs, it's safe around here."

"Don't worry, Corone... Schwi has already checked, and there are no signs of other life forms active within the old capital of the Elf..."

"Ah?"

Corone stared blankly at the location from which the sound came, where a thin layer of smoke and dust filled the air, and in front of Yotsuba Mahiro lay an Abyss crater five meters in diameter.

Before she could react, Yotsuba Mahiro had already jumped down with Schwi.

Looking at the inhuman scene, Corone was filled with bewilderment and helplessness as she said:

"With things already like this, how can I possibly sleep..."

So, he rubbed his sleepy eyes to perk himself up, got up, brushed off the dust, and planned to wait quietly for Yotsuba Mahiro's return.

After landing, Schwi checked for signs of life around her while staying close to Yotsuba Mahiro.

Compared to her wariness, Yotsuba Mahiro seemed quite relaxed, as if she were taking a stroll in her own backyard.

Ruby's eyes rapidly scanned countless data streams as Yotsuba Mahiro, but the results remained consistently the same.

I understand, but I can't.

What kind of human being is this, a type that has never appeared in the database?

Despite appearing relaxed, she possesses power surpassing that of many races and is capable of hunting down a unique individual of the Flügel Jibril, on her own.

They could even easily erect a protective shield to block all the traps set by the Elf here.

That's right, Yotsuba Mahiro perfectly countered the Elf's magical trap, "Forest Sky Capture," simply by setting up a "Phalanx."

It wasn't a poorly made counterfeit scripture imitated by the Ex-Machina, but rather a trap set by the Elf, a magic intended to destroy all intruders.

But she was so powerless in front of Yotsuba Mahiro that Yotsuba Mahiro herself did not feel any pressure, and her heart rate remained very stable.

Suddenly, Yotsuba Mahiro stopped at the top of the stairs.

"Wow, that's really something."

At the end of the long underground staircase lay a strange and incomprehensible scene.

Riku's settlement was a much larger space, with several huge pillars standing in the center.

There were exactly one hundred and eighty-six of them, with countless red patterns engraved on their surfaces, resembling spell marks on Dwarf "spirit armor" or some kind of totem.

The whole structure looks like a temple, or perhaps some kind of sacrificial ceremony.

"... These patterns... are the protective markings of the Old Deus, Kainas..."

"You mean, Kainas?"

He naturally knew about Kainas; he was the creator of the Elf, one of the Old Deus, and also one of the cowards, even looked down upon by Sink Nielbaren.

"Yes..."

"Wow... that's going to be interesting."

Yotsuba Mahiro gazed at the strange scene before him, a strange expression appearing in his eyes.

He had always wanted to have a close encounter with these Old Deus, one that transcended friendship and even life and death, to test the waters and prepare for facing the strongest war god Artosh. And now he'd stumbled upon it so easily?

After the Ex-Machina girl quickly analyzed the origin of these pillars, she tilted her head in confusion.

"However... these spell inscriptions and all the spell inscriptions used by the Elf in the database... are completely inconsistent."

"... Based on speculation... this should be a completely new technique created by the Elf... it should be some kind of powerful 'new weapon' created by the Elf."

The Ex-Machina girl used her processor unit to calculate this result.

"If we're talking about the latest weapons, then that's definitely what I'm looking for."

Yotsuba Mahiro stepped forward, gently touching the engravings on the pillar. The "Alpha Stigma" reappeared in his pupils, and he began to analyze them.

"Void Zero Protection - Theoretical Verification Test Furnace"

It is the newest weapon of the Elf, and it was something that could not be taken away when Jibril destroyed the old capital, so it could only be hidden using magic.

Even the list of developers was written in coded language, which gives you an idea of just how terrifying this thing could be as a weapon.

"Um... Mahiro, can I... come with you to the human settlement?"

Schwi suddenly tugged at his sleeve. His delicate, expressionless face, coupled with his weak voice, made him look utterly pitiful!

But Mahiro bent down and patted her head.

"I don't know either."

Schwi:?

Clearly, she couldn't understand what Yotsuba Mahiro meant by that.

"I'm not in charge of the settlement. I don't know if Riku and Corone will agree, but I can assure Schwi that if they don't, I can let you stay with me and introduce you to some people who are my family."

"... Really?" Schwi blinked her big eyes, looking somewhat like an innocent child.

"Yes, really."

"... Then... make a pinky promise with Schwi..."

She held out her little finger, which made Yotsuba Mahiro pause slightly in surprise.

He didn't know where Schwi had learned that from, but he still smiled and hooked his fingers with hers.

"A liar will have to swallow a thousand needles, and will never regret it."

In the silent underground cave, a human and a mecha girl made their first vow.

When they returned to the surface, Corone and Riku had been waiting for a long time. They did not ask Yotsuba Mahiro what she had done underground.

Schwi, on the other hand, immediately suggested that they return to the settlement together.

Corone was naturally willing, but she couldn't help but look at Riku, waiting for Riku answer.

Riku for a moment, gazing at Yotsuba Mahiro for a long time, before finally agreeing.

However, just as they were leaving, they discovered that a "storm of death" was approaching.

The so-called "death storm" is actually a blue light cyclone phenomenon produced by the interaction between black and gray "Spirit Corpses" when the amount of ash falls suddenly increases.

In layman's terms, it means a massive storm is about to hit this area, and it's moving at an extremely fast speed.

This phenomenon is very common in Disboard.

However, the violent reaction caused by the surge in "Spirit Corpses" will render all nearby races unable to use elves.

Just like the electromagnetic pulse generated by a nuclear explosion, it can cause some damage and malfunction to electrical appliances.

Even the mighty Ex-Machina is no exception. Due to the obstruction of the "Spirit Corpses," long-range observation devices cannot be used, and high-speed movement relying solely on mobility becomes very dangerous.

This phenomenon is even more deadly to humans.

Once encountered, regardless of any protective measures taken, the "Spirit Corpses" contained in the ash will penetrate the protective suit, inevitably contaminating the human body.
