He was the youngest in the office, so he acted modest, but he was a very capable man, as he was brought up by Grandfather Sergei, whose hobby was to train people. And he was certainly a good find.
His ability as a mine manager might actually be part of his assistant skills to create an environment in which Isaac could devote himself to research to the fullest. Aaron’s happy expression when he was working as Isaac’s assistant made me think that he was similar to Great-Uncle Isaac.
–Aaron-san’s great-uncle Isaac love was too deep. My brocon may be losing against. This was a crisis!
Ekaterina felt a foolish sense of frustration.
Isaac, having finished his sketch quickly and taken his eyes off the microscope, looked at the microscope itself with renewed admiration and stroked it gently.
Then he finally came to his senses and looked at Ekaterina with a panicked look.
“Oh, sorry. I got carried away again.”
Ekaterina smiled.
“It’s good that you are concentrating on your important research. Will this microscope be of any use to you?”
“Of course it will. Of course. It’s a great innovation to put a stand like this on the glass and use a mirror to shine light on it from below. It’s so different from other microscopes.”
Isaac patted the microscope happily.
“Are you sure you want me to have this wonderful thing?”
“Of course. Please let me know if there is anything you would like to see in the microscope.”
“Professor, this microscope was developed by the Young Lady.”
Isaac was taken aback by Aaron’s words.
Yes, that was the right response. It was crazy that I could come up with something like this! Because I didn’t come up with it!
The truth was, over the hundred or two hundred years since the microscope was invented, various people made various improvements, and this was the latest form it took.
But I could never say such a thing.
“It’s just an amateur’s idea. As women, when we dress up before a banquet, we check our hair and makeup by shining a light on them in the reflection of a mirror. Perhaps this is a way of using a mirror that the gentlemen are not familiar with.”
I was impressed with myself for coming up with excuses like that

“I see. But it’s wonderful and brilliant, and as Aaron said, Ekaterina is a smart girl.”
Isaac complimented with a childlike smile.
The purity of that smile made Ekaterina’s conscience squirm.
“Oh
great-uncle, what kind of minerals are you looking at right now?”
Ekaterina asked, and Isaac chuckled.
“This? This is a rainbow stone.”
***
“My, this is!”
Ekaterina’s eyes widened.
“I didn’t recognize it. I thought rainbow stones were supposed to be more luminous.”
“Yeah, it’s hard to tell when they’re so small. But it looks like it’s just transparent because of the brightness of the view, but it’s glowing. I was able to confirm the vortex light of magic power, so there is no doubt about it. This is the scrap stone from the area around a large rainbow stone, and I’m trying to figure out if there is an efficient way to extract this kind of fine rainbow stone from it.”
Oh!
The only rainbow stone I saw sullenly was the one made into a brooch during a visit to the Imperial Duke’s residence, but it was a transparent stone with blue light trapped inside and swirling around it.
I guess by “swirling light” he was referring to that light.
That kind of large, strong light could be extracted, but he probably wanted to extract the same light from microscopic rainbow stones.
“That’s for rainbow stone magic, right? You not only mine high-quality rainbow stones, but also try to create high-quality rainbow stones artificially by extracting microscopic rainbow stones?”
