Mystic Dominator

"fighting……"

"You mean the battle of 'us'?"

Hearing the big witch's explanation, Ronald's expression froze.

Judging from the usual attitude of this old spell caster, it is impossible for her to take care of ordinary mysterious side battles. Ronald even suspected that even the caster of the [Original Witch Association] was hunted down by investigators from Passing by downstairs of the apartment, the big witch probably won't be moved.

Therefore, what can cause today's situation can only be that the enemy is using the original scriptures.

And the big witch answered next.

Sure enough, Ronald was right.

I saw the old practitioner sitting in the carriage nodding lightly, and then he opened his mouth to explain:

"That's right, that's who we are."

"Before today, I really didn't expect to catch a book holder here. Although I already know that this era is different, I still haven't been able to adapt to these changes..."

Seeing the big witch's downcast expression.

Naturally, Ronald would not speak unwisely at this moment.

Maintaining the silence in the carriage, he just quietly called out the original scriptures, and then murmured the poem:

"His name is Styx.

The black water flowed down to the foot of the dark and steep cliff.

..."

The casting this time is different from the past.

In the past, Ronald simply recited the mantra, and then let the scriptures automatically guide the power out.

But after negotiating with the big witch in the past few days.

This old way is abandoned.

While chanting the incantation, Ronald first mobilized the magic power in his body, and used it as the starting point of casting the spell to construct the spell under the guidance of the original scriptures, and then the power of the original scriptures began to maintain the operation of the spell.

And the effect obtained by doing so.

That is, Ronald's control over spells has improved a lot.

The black mist, which was originally flexible like an arm and finger, is no problem at all even if it is used for fine work of adjusting the tourbillon.

Of course, after the black mist wrapped around his hands.

The first thing Ronald did was to immediately limit the scope of the investigation.

Sitting next to Ronald, the big witch also saw this scene in her eyes.

Looking at Ronald who didn't care to hide it, the old caster smiled.

Immediately, the big witch asked where the coachman was:

"Mr. coachman, do you mind if I speed up the carriage?"

"It won't cause too much burden on the body."

The coachman immediately replied skillfully:

"Please feel free."

"..."

So, for the first time, the great witch took out her original book in front of Ronald.

Gently raising one hand, an old bound book with yellowed pages was taken out of her clothes by the big witch. She was already so proficient that she didn't need to turn the pages, and she was about to speak the spell just holding the original book.

And sat beside the great witch.

Just seeing the cover of this original book, Ronald felt his whole body become tense.

The reason why Ronald would be unconscious is actually very simple.

Because this is a precious memory that he only had when he was in school.

——The name of the original book is on the cover.

——"Introduction to Fluid Mechanics"

There is even the name of the author Prandtl written on the cover below.

The reputation of this book is so great that anyone who has received compulsory education should be somewhat impressed.

The masterpiece of the father of aerodynamics and the father of modern fluid mechanics...

Who would have thought that it would be possible to see it again in another world?

Immediately afterwards, there was the voice of the big witch chanting the 'mantra' softly:

"Significant changes in density or volume occur principally in gas and vapor streams when the pressure difference is large..."

After chanting the 'spells' in various senses, the invisible airflow that Ronald had seen many times immediately rose up around the carriage. While protecting the stability of the carriage structure, the airflow brought good acceleration at the same time.

Of course, the Grand Witch made no common-sense mistakes.

Even though it has been accelerated, the horse-drawn carriage running on the streets of Springs still maintains a fairly suitable speed, so as not to attract people's attention.

As for Ronald...

He was still sitting in the carriage, but his current mood was quite delicate.

When he was still studying in school, mechanics was a sore spot in his heart, but after graduating to work, and even traveling to another world, could he still meet this "old friend"?

Almost subconsciously, Ronald let out a long sigh of relief:

"call--"

Sitting next to Ronald, the Grand Witch naturally saw his reaction.

So she turned slightly towards him, and the big witch asked in a concerned tone:

"Mr. Ronald, are you all right?"

Quickly adjusted his mentality, Ronald smiled and shook his head:

"No... nothing."

"Just remembering something from the past."

"..."

However, even so, how could an elderly witch fail to notice Ronald's eyes just now.

Although the expression was a bit subtle, the big witch still generously picked up the original book:

"Ronald, do you want to see my original book?"

"If it's just for looking, I don't mind much."

Ronald replied without even thinking:

"No, this is really unnecessary."

"I haven't figured out my own original scriptures yet, how can I have the idea of ​​watching other original scriptures."

"..."

He watched Roan carefully for a few seconds.

The big witch shook her head with strange eyes, and then put the "Introduction to Fluid Mechanics" back into her clothes.

Next, both of them stopped talking and began to quietly watch the situation outside the carriage.

The driver who works for the bureau is very good at driving.

Even though the carriage didn't run at the speed he was used to driving, he still skillfully crossed the streets of Springs and rushed towards the Baisha District without a moment's rest.

In fact, if you think about it carefully, Ronald once saw the appearance of Baisha District from a distance.

That was the scenery he saw on the cruise ship when he first arrived in Springs.

Baisha District, as the name suggests, is an urban area close to the coastline. Many industrial facilities are located in this area, so the environment there is quite bad.

Looking at it from a distance, it is really an impression of machines roaring in the steam age, and chimneys exhausting exhaust gas day and night, polluting the air.

And as the carriage moved forward.

The changing street scene also proved that there was no problem with Ronald's impression.

After approaching the Baisha District, the green plants on the surrounding roads disappeared directly in front of the eyes, and the ground was directly laid with truck tracks for convenient transportation of goods. Busy and tired workers, wearing dirty clothes, ran back and forth here.

As for the surrounding buildings, they are also large square buildings made of red bricks.

Only in higher positions will some windows for ventilation and lighting be opened.

Quietly watching the scene outside the carriage, the big witch wrinkled her nose and said in a dissatisfied tone:

"This place... I don't like it."

Ronald also shrugged:

"Who would like a place like this?"

"..."
