A magic engine, in place of a steam engine in a previous life, is also something to say.

I have it in my hand right now... like an egg it will be born with.

"Ekaterina! What's up, you look pale. Are you sick?

"No! No, it's just that this is... tough... tough, research. Enough to change the world..."

Aaron was breathtaking when Ekaterina answered that to Alexei, who was worried.

"Ma'am, do you understand? Did you understand the value of this paper, which academics did not understand, just at first reading?"

"No. Um, I don't understand everything. But as long as you have rainbow stones, you can continue to activate magic.

In a land without water, you can keep calling water to produce springs. You can also wake the wind only where you need it and move the windmill as much as you want. Even if you felled the forest and didn't use it as firewood, you could keep the fire. And plowing the earth with the magic of the earth. If we can do that… how much will people's lives change? "

It's a very big rainbow stone magic formation right now, but I'm sure it will soon be improved, miniaturized and diversified.

And the first magic activation is also possible with artificial equipment. I'm sure it will.

I remember. The day I saw your brother and the Imperial City, when I looked out over the Imperial City from the temple tower. I remember Tokyo in my previous life and wondered how vast and how gray it was.

Could this paper be the way to turn this royal capital into that Tokyo?

"Uncle Isaac is a genius without a whole lot of... It's an amazing genius to have a name in history."

"Yes, it is. Dr. Isaac Yurnova is the greatest genius in the history of the Empire, this paper is proof of that.

But the lady is also really smart. I just read the paper at first reading and often went that far. It was just ridiculous to say that 'this cannot be called a mineralogy paper', such as the Academy of Sciences. Not even at the feet of a young lady, such as the old scholars. "

No, Mr. Aaron, lowering the scholars at the academy and raising me must be because you are too loving, Uncle Isaac.

"Aaron is right. I learned about this thesis before your grandfather, when your great-uncle came to your grandfather and gave you this kind of stuff, but at the time I had no idea how likely it was to be."

If your grandfather was born, your brother is ten years old or younger! Absolutely!

"Your grandfather understood instantly. He was very happy. Excellent, Isaac has said many times that he is a genius... You still look like your grandfather.

Only Yurnova will be able to accomplish the practice of Rainbow Stone Magic Formation. We need to prepare a huge amount of rainbow stones. The cost is huge, too. But if it can be put into practice, the effect is immense. You're right, it could change the world. So I want you to help me. "

Ekaterina turns back on Alexei with a serious look.

Honestly, it's not where I can pull my hips. This, it's a project. It's beyond you. History better move then. It's not the history of a country, it's the history of the world or the history of mankind.

But. Your brother said he wanted help.

Who am I?

I'm a bracon! (Gripping fists)

I don't even have a slightly dumb escape from reality though. All right, I'm hungry.

For now, greenhouse gases and warming, which have been a problem in previous lives, should not be the same thing because they do not use fossil fuels.

Because of my previous life's knowledge, I know that's not the only problem, it's not all good. But there's also a lot of good things.

And more importantly, because your brother wants it.

Let the world change!

"If you succeed in the practical application of the Rainbow Stone Magic Formation, let Yurnova's name transcend the Empire and be inscribed in the history of mankind. It's a compliment to your house. More importantly, it is your grandfather's will, and I will do whatever your brother wants."

"Thank you. It's a pleasure to have a family that can unite your heart"

Alexei smiles.

"But I want you to take care of one thing. Don't say anything else about this for the time being."

"Do you threaten to be preempted by other houses?

"No. Some...... no, probably because the majority of noblemen threaten to rebel against their inability to monopolize magic"

Oh, and Ekaterina breathed.

Right. Now, magic is a symbol of nobility. Having magic is a great pride of nobility.

But the Rainbow Stone Magic Formation needs a person with magic for the first startup, but the continuation only needs to inherit and add to the Rainbow Stone. Even people without magic can benefit from magic.

The value of an individual's magic might be reduced. No, I will.

And... civilians rise up? … the empire to democratization, the world moves…?

"Some of them will be in radical action. - I swear to God, I won't give you any danger. In case anyone maligns you, they will be rewarded a thousand times more. Must be."

... brother, the light of neon blue eyes. I remember the phrase 'graceful ruthlessness'. It's the title (part of) of a book I read in my previous life.

Such a brother is cool and nice.

"When something happens to me, you become the Duchess of Eurnova. If there are no men to inherit the trail, the Imperial Law now stipulates that a woman can inherit the governor.

Then I want you to take over and finish this. "

When something happened to your brother...

I'll take over the title, which means - your brother.

Oh, that?

Hey, hey, wait for yourself.

"Ekaterina!"

Alexei raised her voice like she was screaming and took my sister's hand.

"What's up, please, don't cry. You don't like being a duke?

"No... no, but... Something about your brother…"

Ekaterina is blurring and weeping.

Wow. I'm not stopping.

Hold on, yourself! Don't Alasser cry, your brother's in trouble.

But it's not Alasser himself who's crying. Fifteen years old, partly even younger than her age, everything in the world was scared and drawn after her mother's death, and only her brother is Ekaterina's self, the courtier she relies on.

And even Alasser's self, in case your brother is gone like your grandfather - I can't, I'm going to cry. You're already crying, but yourself.

It has been so striking since I saw it on the smartphone screen in my previous life that it was the only healing of life in a straight line of overworked death. When I was reborn to my sister, she was always a man who absolutely loved me and could do a great job, but she was a healthy child who had been having a hard time at an early age. More and more, I can do anything for your brother! I think.

But what if your brother's gone? No, I mean, he'll be gone, the...

Just thinking about it is hard! Seriously, I'm going to have zero energy to live. No, I will. Determined.

Wow!

I'm afraid of the word "something" to your brother just because you can imagine the great transformation of society that can happen in the wake of the Rainbow Stone Magic Formation!

"Sorry...... it was my fault. I told you delicate, careless things. Forget it."

Alexei comes to Ekaterina's side and hugs her sister.

"My chest is about to rip open when you cry. Please don't cry - God won't even forgive you, such as making you sad. If you grieve, I will never die. Even if I cross the river of oblivion, I won't forget you. I will definitely come back to you. So don't cry, please. Don't cry..."

Mi...... the beauty of your brother whispered in his ear. A little tremor.

The myths and legacies that there is a river of oblivion flowing between this world and the afterlife have been around the world in previous lives, but there have been similar legends in this world since the time of the Astra Empire. - I remembered my past life's memories. I didn't forget your brother when I crossed the river of oblivion in real life.

I died once.

In the days leading up to my overworked death, I was completely paralyzed and unable to feel things properly anymore, but while my life was gradually being shredded, I knew it was bitter and hard.

Dying is, after all, something that hurts or is painful.

I don't want your brother to think that.

"Lady."

Ivan, a squire, spoke softly to Ekaterina, who kept crying in her brother's arms.

"Please don't cry. I'll protect you, my lord, so nothing will happen to you. Your Excellency will return safely to the lady that my body has been torn into eight pieces. So there's nothing to worry about."

……

Gusu, his nose rings, and Ekaterina finally looks up and looks up at Ivan.

Yeah, Ivan is just like Mina, serving as your brother's escort.

"... Ivan, strong?

"I've never met someone stronger than me."

Blatantly, Ivan says.

Wow. Ivan, which protagonist is that?

"... don't hurt Ivan either, come back..."

"Okay. If that's what the lady says, I'm not going home hurt one of you."

Also, Ivan says, in a teasing and bright voice.

I didn't know, Ivan's the kind of person who's fine and lies.

I understand because I say I won't get hurt lightly. If there is imminent danger to your brother, I'm sure Ivan will protect you, even if you're truly torn apart. I guess he's really, really strong enough to go beyond the realm of man.

"... thanks, Ivan"

"You're welcome, ma'am"

To Ekaterina, who finally stopped crying, Ivan gives her the usual loving smile.

Alexei also smiled relieved and wet her sister's tears with her fingertips.

"I'm sorry I didn't think enough of you."

"No, brother... I am ashamed that what I have done will upset you on your birthday. Please forgive me."

Looking up embarrassed, Alexei opened her eyes.

"Forgiveness, etc. It's what you think of me, I'd rather you forgive my insensitive words.

I swear I will never leave you alone. I didn't even know what it meant to celebrate my birthday, thank you for weeping for me and all that. Glass pens were a great gift too, but nothing could be more beautiful and honorable than your tears. My dear Ekaterina. "

... Ugh, sweet. That's Siskon, brother. I'm sorry I've been such a rough sister.

If anything happens to your brother, I panicked. I'm usually a Bracon, too. Don't embarrass your brother.

All right! We'll try again.

Shape your glass pen business before your brother starts working on Rainbow Stone Magic Formation. Let that experience be useful for your brother!

"I have nothing to be afraid of if you even want my brother. We look forward to the day we will work together on your grandfather's legacy. So please take care of yourself."

"Oh. If that's what you want, let's do it."

... nobler than anyone, proud brother. It's very ironic, though, that what your brother is trying to do might inspire you to end your aristocratic society.

Instead, with our Duke's home taking the lead, we might be able to move towards a new system in soft landing, rather than a bloody transformation like the French Revolution.

Seems dull, but I'll do my best to make sure it does.

If your brother will stay by your side, he will gain as much power as he can. I'll do anything!
