I'm fighting Kal'tsit? Really?

"Later, it was optimized into two forms."

This female demon was clearly different from the more mature members of her kind, speaking in a very colloquial way. "After all, you are a friend of the female demons, and the valley would certainly welcome you to settle here. But usually, after a female demon has chosen a partner, if she intends to stay with him, she will choose to leave the group to give birth to the child, and then return to the group with the child after the partner has died of old age."

“Ah, of course, there are also those who can’t find a partner.” Her tone changed again. “There’s nothing we can do then. We can only find someone stronger to persuade or kill, and extract the part from their body for reproduction using a spell.”

"That's why the old woman is worried," the frivolous banshee sighed. "The banshee queen's spells are among the most powerful. Ramalen clearly used the spell in the courtyard to ambush you, and then took advantage of the moment to knock you unconscious and fall asleep—"

Ga.

The thorn's voice came from high above. After catching the unconscious leader of the banshees, it also hoisted the banshee who was giving a long explanation into the sky.

Meeting Gerald's gaze head-on, Ramalen coughed lightly and explained, "This... is simply because I combined the fertility spell with the thorn spell. In fact, you've experienced it yourself, otherwise your strength wouldn't have recovered so quickly."

"Also, you don't need to worry about the child; this is just practice."

She spoke quickly and urgently, her tone completely lacking her usual elegance and composure.

Gerald nodded silently.

Hard to say.

------

The valley remained calm and peaceful throughout the day.

Even though some funny things happened in the courtyard, the final interpretation still rested with the older female demons, so for most of the younger female demons, life didn't change much.

Except for Nastya.

After seeing the Pegasus, dressed in clothes belonging to the Valley, descend from the courtyard, she knew she had to find an opportunity to ask him about Originium Arts and levitation.

In the morning, she secretly bypassed her usual friends, set off from the forest, avoided the curses she would encounter along the way, and began to follow the other party's trail.

She was well aware that such behavior would immediately attract the attention of the other party and the Banshee Queen, but this was the only way for her to access the knowledge she wanted—she still needed some time to practice before she was able to leave her tribe and live independently.

At noon, her tracking paid off. After finishing her breakfast, the Queen of the Siren brought the Pegasus to the infirmary at the valley waterfall.

Although it was unclear why the Pegasus would occasionally stick out its tongue, looking as if it had eaten something terrible, fortunately, the Banshee Queen seemed to have left earlier due to other matters.

What pleased her was that she was neither deliberately driven away nor punished by the Banshee Queen.

This shows that she has gained the other party's approval.

So she strode quickly toward the side of the cottage.

The Pegasus stood there, quietly gazing at the leaves drifting downstream in the distance, before turning around after hearing footsteps.

Gerald looked at the little banshee who had left a deep impression on him and greeted her with a smile: "Oh, what's your name?"

"Nastya Runorui." Nastya, who was running over as fast as she could to avoid the other party changing her mind, quickly blurted out, "May I ask you some questions?"

"Is it about battle? Or the land beyond Kazdel? Or perhaps knowledge?"

Gerald asked with great interest, a listening spell hidden behind his ear.

“Yes, it is knowledge.” Nasti nodded firmly. “Besides, if this request is not so presumptuous.”

"Could you please show me what it feels like to float in the air?"

Chapter 54 This kind of thing happened (TM) Reikalshi

This is indeed a surprising request.

"Have you eaten anything?" Pegasus suddenly asked. He glanced at the sky above, where the wind did not yet carry the aura of the curse. "I saw you following us since early morning, but you haven't had time to eat anything yet, have you?"

"Ate."

Although Nasti didn't understand the question, she answered truthfully: "The Banshee Queen specifically requested that everyone eat breakfast after singing every day. If any of the three meals is missed, a spell will seal our mouths, and we won't be able to speak for a whole day. Considering that sometimes we need to think continuously when studying, I think this approach is very inefficient."

Gerald glanced to his side instinctively, then looked back at her: "You sound like you're not too happy with this rule... though I would feel the same way if I were in your shoes."

He had just eaten a spicy pancake; he shouldn't have eaten in his dream.

As for the little demon girl in front of me, she doesn't look like a docile person at all.

Knowing the rules yet still doing this, she might be more like a lich than a banshee.

"Alright, anyway." Gerald, having formed his initial impression of the other man, held up one finger: "Since you've already had breakfast, it's best not to do anything too strenuous. Remember not to do somersaults or turn your head upside down. Although a morning is enough for you to digest, I don't want to see you vomiting everywhere. Got it?"

Nasti nodded.

The next second, her body was swept up into the air by the wind.

Even though the wind wasn't fast, and it felt more like it was embracing and lifting her into the air, it still startled her completely—even after a banshee reaches adulthood, it's difficult for her to learn how to transform the abstract concept of wind into a real spell, even for the banshee queen.

The first sensation is weightlessness.

Many young sirens would choose to leap forward from the waterfall in the valley, letting their bodies plummet downwards with gravity. Fortunately, the riverbed was not shallow enough to support their fearless behavior.

But the old woman caught them doing this, and everyone was cursed several times, sleeping from Monday to Sunday.

Nasti tried several times, so her punishment was the harshest.

But the feeling is completely different now.

The textbooks available in Kazdel were too simplistic, while the books in the Banshee Clan's collection were far too ancient; neither could explain the current situation to her.

Because this is not a natural phenomenon, it is real weather manipulation.

When she regained control of her body in mid-air, and even tentatively took a step, feeling something beneath her feet but unable to see anything, Nasti's eyes finally shone with a dazzling light.

It was a kind of fervor that intertwined astonishment and excitement.

“Not bad, right?” Gerald walked up into the air as if stepping on stairs, standing next to Nastie who seemed to be walking on a balance beam. “You know, if it’s just about flying, many people can do it. As long as they use a reaction force… Do you know physics?”

“I have actually studied it.” Nasti was still panting, carefully maintaining her balance until her feet were firmly planted in the air. “His Highness captured quite a few books for us, including a handwritten one called Fluid Mechanics… It’s a bit difficult, and it will definitely require other books to aid in reading. I’ve been searching for a long time but haven’t found any. But deciphering the independent sections is not a problem.”

Okay, this is already beyond his reach.

Gerald silently chose to keep quiet. Lately, something seems to be wrong with him. He's an educated man, so why does he always seem to run into a bunch of geniuses?

"I believe that Originium Arts is actually a system in itself."

Nasti frantically gestured her thoughts in the air, completely forgetting how to maintain proper respect, though Gerald never cared about such things: "There are inputs, outputs, and a need to maintain its own dynamic balance, and it is composed of several different modules. The result achieved by Originium Arts is the output result, but the question is how we observe this system."

"Just like I can't understand how you manage to achieve this dynamic balance in me by manipulating the wind, this process is a mystery to us."

"But the thing is, you can do it, and you've proven it."

She gritted her teeth, jumped up, and then landed back in her original position with unease—the wind, or rather Gerald who controlled the wind, easily caught her, preventing her from falling.

“Did you see that? This dynamic balancing ability.” She took a soft breath, her fervor growing stronger. “The other parts of the system aren’t difficult at all, including real-time checks on the balance of objects and subsequent feedback. All it takes is a machine created with incantations. I tried to make one a few times, but I didn’t succeed, and it’s not replicable. But I know that this is something that can be done entirely by one’s own power!”

"Do you understand? You are the most crucial part of this!"

"Once we know how to summarize and generalize the calculation formulas for this fluid, and then consider turbulence control and vortex ring stability, we can always maintain an object—"

The little demon's words were fading into the distance.

I'm sorry, I don't understand.

Gerald could roughly grasp the concept the other person was trying to convey, but he genuinely couldn't understand it.

This must be around 900 years into the Terran calendar, right? Why would someone bring books containing this level of knowledge to the battlefield?

When he was memorizing history, he only remembered that the first Originium internal combustion engines were built around 800 in the Terra calendar. But could that have been iterated to fluid mechanics and systems so quickly? What kind of influence have you guys had on that little banshee?

……

As Gerald was thinking this.

In the far distance, infinitely far from the valley, a lynx wrapped only in tattered rags had just found a dilapidated hut to rest in.

She involuntarily sneezed, startling the monster behind her that had shrunk in size.

……

Let's return our perspective to Gerald.

“If I’m not mistaken—” Pegasus shook his somewhat dazed head, trying to clear his thoughts, “You want people to be able to move freely in the air. But what is your purpose in doing this?”

"A city."

Nasti's words showed no sign of confusion; she answered Gerald's question directly and clearly.

"I've heard that people outside of Kazdel have come up with a way to put the city on tracks and use Originium to power it, making the city move."

“You come from elsewhere, so you should know about this, right?” The little banshee lowered her eyes, but hesitated slightly, wondering whether she should say these words: “They have figured out a way to escape the natural disaster, to escape what they don’t want to come into contact with.”

"So I think, since they don't welcome the Sarkaz, then we should too."

"I hope that one day, Kazdel will no longer be exiled by foreigners, but by Kazdel flying in the sky—"

She looked at the person in front of her and said, word by word.

“Exile those who do not welcome us.”

……

Gerald was somewhat surprised.

This was something he had never imagined in his previous life, because it was beyond normal logic and imagination—well, perhaps he had similar dreams many times when he was a child, especially on the day he realized his talent for Originium Arts.

The difference is that Nasti's lifespan will be very long, long enough that when he returns to reality, he will still see this young banshee deeply engaged in some field. Of course, perhaps in the end he will see her voluntarily giving up her dreams and returning to the valley to retire.

But actually treating this idea as a dream and working hard for it isn't such a bad thing.

"Lamaren."

"I'm here."

The Banshee Queen, dressed in formal attire, appeared beside Pegasus almost instantly, without even a trace of her veil fluttering, as if she had never left.

Nastya, who had been so excited, froze on the spot as if struck by lightning, her eyes suddenly dimming. Her lips trembled slightly, but she couldn't utter a single word, as if she had fallen into an unseen abyss.

“Don’t worry,” Gerald said gently, noticing the hesitation and fear on the little banshee’s face. “I’ll make sure she absolutely won’t do anything to you. I swear on my life—”

However, before he could finish speaking, Tianma suddenly frowned, feeling a sharp pain in his waist, as if something sharp was pinching him hard.

He endured the pain in his waist, silently turned his head to look at the Banshee Queen whose face had darkened again, and sighed.

"In short, the reason for bringing Ramalen over was simply to test the feasibility of the idea."

"test?"

Two questions rang out simultaneously, their faces filled with confusion, clearly unaware of Gerald's so-called "test".

Gerald did not answer immediately, but calmly glanced around at the scene.

To be honest, he wasn't sure what to expect when he thought about what was going to happen next.

However, if someone does something knowing that they *might* be able to do it, it would be a tremendous encouragement for her, who has a dream.

Therefore, why not take this as his first lesson in instructing these young succubi?

It's still a long time.

“We need to find a place that won’t affect the valley, preferably outside the valley.”

After much deliberation, Gerald finally made up his mind and said, "Ramallen, I might need to ask you to cover up our movements. It could be quite a commotion, and there's a chance we might not be able to exert enough force. You need to consider the risk of us both falling from a great height, but I think it should be fine."

"Wait a minute." Ramallen interrupted Gerald abruptly, pulling him to face her and looking him straight in the eye: "What exactly are you trying to do?"

And then, for the first time, Gerald averted his gaze.

"It's probably just... a simple test, right?"

"Regarding how much force would be needed to make a house fly, and how many other issues still need to be considered."

Chapter Fifty-Five: Ethereal Above the Clouds

The three entered the clinic.

The valley's architecture resembles that of Gerald's previous medieval era. The infirmary's interior is primarily constructed of wood for its walls, while stone is extensively used for beams, window frames, and doors. Near the waterfall, the roofs are mostly sloping, covered with heavy wooden shingles, and some walls are embedded in the stone. Thorns and vines surround the window frames, and ravens occasionally perch on the beams.

This medical clinic was proposed by Ramalyn herself, but it was rarely used.

All wounds, large and small, in the valley pass through the hands of the Banshee Queen or the older Banshees. As for the valley now, the young Banshees have not yet grown up, the core forces are ravaged by war, and the older Banshees are even less likely to leave their people to go elsewhere.

In addition, the valley environment differs from Kazdel, providing a natural barrier against disease, making it difficult for illnesses to truly invade this area.

But that doesn’t mean the clinic is useless.

“Pain relief, sleep aid, curse backlash.” Gerald brushed his hand across the rag spread on the table, on which bottles and jars were arranged, each labeled, surrounded by incantations for regular cleaning and environmental adjustment. “They’re well-preserved; the person in charge of this place must have put in a lot of effort.”
