Ekaterina PoV:

I suddenly remembered the day when I was touring the imperial capital with Big Brother, overlooking the city from the bell tower of the temple. It reminded me of Tokyo from my previous life, and I thought how vast and gray it was.

Perhaps this paper would be the path to change this imperial city into that Tokyo?

“Great Uncle Isaac is an unmistakable genius… An amazing genius who will go down in history.”

“Yes, he is, Professor Isaac Yurinova is the greatest genius in the history of the Imperial Kingdom, and this paper is proof of that. However, the young lady is also truly intelligent. How could you know so much from just one reading of the paper? The old-style scholars are no match for you, milady.”

No, Aaron-san, the reason why you are lowering the academics of the academy and praising me to such heights was the fact you admire Great Uncle Isaac too much.

“Aaron is right. I learned about this paper before Grandfather’s death when Great-Uncle Isaac came to him and told him that he had written something like this, but at the time I had no idea how much potential it had.”

Before Grandfather’s death, Big Brother would have been under ten years old! That’s normal!

“Grandfather understood immediately. He was very happy. He told me over and over again that Isaac was a genius. You are just like Grandfather. Only Yurinova can accomplish the practice of the rainbow stone magic circle. We need to prepare a huge amount of rainbow stones. The cost would be immense. But if it can be put to practical use, the effect will be incredible. As you say, it could change the world. That’s why I would love to have your help.”

Ekaterina looks back at Alexei with a serious expression.

To be honest, I’m more than a little hesitant. This was beyond anything I’ve ever seen in a project. History was in motion at that time. This was not the history of a single country, but the history of the world, the history of mankind.

However, Big Brother asked me to lend a hand.

Who am I?

I’m a brocon! (clenched fist)

Although not without a bit of stupid escapism. Okay, I’ve made up my mind.

At any rate, the problems I had in my previous life, such as greenhouse gases and global warming, shouldn’t occur in this world because we don’t use fossil fuels.

With the knowledge from my previous life, I understand that there were more than just difficulties, and not all of them were good. But many good came out of the industrial revolution too.

And most importantly, it’s what big brother wanted.

Make the world change!

“If we can succeed in putting the rainbow stone magic circle to practical use, the name of Yurinova will be engraved in the history of mankind, beyond the Imperial Kingdom. It would be a great honor for our family. Above all, it was Grandfather’s wish, and if that is what Big Brother wants, I will do whatever it takes to achieve it.”

“Thank you. It’s nice to have a family that is united.”

Alexei smiled.

“But I want you to be careful about one thing. You must not speak of this matter to anyone else for the time being.”

“Is there a risk that the other families will get there before us?”

“No. There is a fear that some… well, perhaps most of the nobles will rebel against the loss of their monopoly on magic.”

Ah, Ekaterina gasped.

I see. Right now, magic power is a symbol of nobility. Having magic power is a great pride of nobility.

However, the rainbow stone magic circle requires a person with magic power to start it up, but it can be continued as long as the rainbow stone is added. Even people without magical power can benefit from the magic power.

The value of an individual’s magical power may drop drastically. No, it will.

And… the rise of the commoners? … Will the empire and the world move toward democracy…?
