“Ekaterina, you know about the rainbow stone magic circle? That’s about right. Natural large rainbow stones may contain low quality magic power or a mixture of attributes, so the results of magic circle activation would be inconsistent. So, I decided to crush them and sort them by quality and attributes, hoping to extract fine iridescence from the waste stones that I had been throwing away. I thought it would be a shame because some of them are small but of high-quality and rare attributes.”

So, the aim was to achieve uniformity of quality and single attribute? I see.

Improvement had already started before the trial….that was impressive. As someone who was an SE in my previous life, I could understand how important it was to notice problems and improve them at the design stage.

There was already a perfected rainbow stone magic circle in this person’s head. So real that he could find problems in the simulation in his head. He was really a genius.

Something that would move history was born from the brain of this person in front of me. Even now, a turning point in human history was being worked out right in front of my eyes.

Wow, that made me shudder at the thought of it. It was so moving that it gave me goosebumps.

“Metals such as iron, gold, and silver are smelted by melting ores at high heat. That method cannot be used for rainbow stone, right?”

“No. Rainbow stones are not melted by heat like metals. It is better to think of it as a kind of gemstone, but since it is a condensation of natural magic, it has different properties from ordinary stones… It has not been studied much so far, so I don’t understand it very well yet.”

“My… that’s very interesting.”

It was like a new continent of knowledge that had never been explored before. An intellectual adventure itself. It was so romantic!

Isaac smiled at Ekaterina, whose eyes were sparkling.

“I’m glad to hear you say that. I don’t think ordinary young ladies would be interested in something like this.”

“For my part, I’d be surprised if I wasn’t interested. What else can be more exciting than this? I am honored to have been introduced to Great Uncle’s research. It’s exciting to see how it has the potential to entirely change people’s lives.”

“It’s my pleasure. Thank you.”

Isaac reached out and patted Ekaterina’s head.

“Ekaterina is a clever girl, you are indeed Alexei’s sister, Alexei was also very clever since he was little, and I was always impressed with him, but you seem to have a different cleverness than that child.”

A genius called me smart! I was so embarrassed.

No, this wasn’t the time to be embarrassed, sorry for being a fraud. I wasn’t clever, I just knew in my previous life what civilization would be like a few hundred years from now. If I think that I was smart, it would be the end of me as a person, I must remember that!

“Once again, thank you for this microscope, Ekaterina, it makes me happy, I haven’t received anything this nice since my brother gave me a cupboard when I was little.”

“A cupboard…you say?”

Ekaterina tilted her head.

Great-Uncle, so you called Grandfather Sergei [my brother]. I guess it was already been a long time ago. The way he called that white-haired gentleman was a bit childish, it was cute.

when he was a little boy, Grandfather would have been a child too. What kind of situation would it be for a child to give a cupboard to another child, and be happy about it?

“I have always been attracted to minerals, and when I was little, I used to pick up rocks and bring them into my room every day. But I was always scolded about it, and it was always thrown away. I can’t blame them now, but I was sad then.”

He continued.
