Ekaterina PoV:

And a magic circle! It was a romance topic in my previous life but in this world. Various institutions academically studied magic many times, and you can find it in most magic control books. However, the researchers concluded that the effect of amplifying magic power was not that great for the amount of time and effort it took. Hence, academic institutions almost completely abandoned efforts into studying their practical effect now.

Yet it could also be a good idea to utilize the magic of the rainbow stones instead of using the magic of humans as a source of power. With a magic circle? How do they do that?

By the way, Yurinovas first Lord Sergeis favorite sword had Rainbow Stones inlaid in it. If anyone with magic power wielded it, it would activate weight reduction. About 400 years ago, humanity developed the means to use rainbow stone technology.

However, the condition to activate it was the innate magic power of the person, and it would only work while the person was holding it. But in theory, magical device users could sustain the spell with a magic circle and rainbow stones, so wouldnt that be amazing?

The first chapter consisted of examples of the uses of rainbow stone magic.

There were many examples detailing the uses of rainbow stone magic in various parts of the empire, including Lord Sergeis beloved sword. Wow, this book was awe-inspiring. Great uncle, you must have been a fieldwork demon.

Chapter 2, The Effects of the Magic Circle.

Ugh this was tough for me. I dont fully understand it. But I concluded that various parties had researched magic circles mainly to amplify magic power. Magic circles also had the function of enabling the activated magic to remain activated continuously, so as long as there is a continuous source of magic power supplied to it.

Chapter 3, The Connection between the Rainbow Stone Magic Power and the Magic Circle.

Yes, this is the crux of the matter. With the magic power, a human being can apply the effects of a magic circle by using their own magic power and channeling it into the magic circle. But how does one extract the magic power of the rainbow stone to make it flow into the magic circle to activate the said magic circle?

Therefore, in the end, researchers came up with an idea of how they would incorporate the uses of rainbow stone together with a magic circle. They discovered that when a humans magic is channeled into a magic circle, there was an entry point at which the magic flows into the circleFrom there onwards, they tried mimicking that process by setting up rainbow stones to guide the magic with pinpoint accuracy, which distributes the magic power stored by the rainbow stone to the magic circle.

Chapter 4, Rainbow Stone Magic Circle Practice.

The requirements to activate it. Thats a lot of work! How much rainbow stone could it possibly need?

The quality and condensed magic should be of the same kind. Collecting this many rainbow stones of the same type of magic power condensed in high purity

The magic circle is also huge. I wonder who will be able to draw all this without any hiccups

But I figured it out.

It means that magic power can be extracted from minerals and used sustainably.

This is it. This concept, this idea ushered a revolution in the world in my previous life.

Oh, my hands are shaking. How amazing.

This would change the world in more ways than one.

Ekaterina lowered her hand that was holding the leather folder onto the table. The folder clattered against the table as her hands shook.

This. Is. An industrial revolution.

*******

This is a magical engine capable of mimicking the steam engine from my previous life.

I now hold it in my hand, like an egg from which it would be born.

Whats the matter? You dont look well. Are you feeling sick?

No! No, its just that this is this is this is very, very serious research. Its groundbreaking

When Ekaterina replied to a worried Alexei, Aaron gasped.

Do you understand this, young lady? You understand the value of this paper, which the scholars of the academy could not even comprehend, after just one reading?

No, I dont understand all of it. However, as long as we have rainbow stones, we can continue to perform magic, right? We could create a spring in a land where there is no water. We can make a windmill work as long as we want, creating wind only where we need it. We can keep a fire going without cutting down the forest for firewood. We could use the magic of the earth to cultivate the land. If we could do those things, how different our lives would be.

Right now, the potentials of rainbow stone magic circle is huge, but Im sure the researches into this topic will soon be improved, compartmentatlized, and diversified.

And the initial activation of the magic will be possible together with artificial equipment. It would happen.
