As expected, the empress was not with him, but she was accompanied by Charlotte Alina von Rinal Shawlo, the sister of the former emperor of the Shawlo Empire and the sister of the current emperor.
"Welcome, Your Highness."
Jin was planning to return to Horai Island in the afternoon, but his plans were changed.
He was escorted by a female knight who looked new to him.
"It is a pleasure to meet you. My name is Emilia Frot von Galarroa, a member of the Shoro Imperial Guard.
Emilia bowed to Jin and Erza, bending almost 90 degrees at the waist.
"Oh, I'm Jin Nido."
"Elsa Nido."
Jin and the others also introduced themselves.
Emilia is a small girl, still a little bigger than 11-year-old Ernst, but she will probably overtake him within the next two years.
"It is a great honor for me to see the faces of the renowned Jin Nido and his wife, the court-appointed healer (Reichsanstalt).
"Yes, yes."
He seems like a very serious man. That's why he's in charge of the future emperor.
"Your Majesty doesn't come here every day, that's why I've followed you."
Charlotte, the Empress's sister and Ernst's aunt, says,
"......What is the first and second in the line of succession to the throne doing here ......?"
Jin couldn't help but sigh.
At the same time, he instructed Ernst to contact Ro-kun through Reiko and have him send a "shinobi unit" to the site, just in case.
Unaware of this, Ernst was being taught engineering magic by Jin.
Yes, that's right. Yes, that's right.
"...... like this! <
In Ernst's hands the bronze deformed into a ...... distorted sphere.
"Oh ...... no!"
Ernst's shoulders slump.
"No, that's a good point, Your Highness. Come on, try again."
"Yes. ......<!"
It's better than before, but it's still a distorted sphere.
"It's difficult. ......"
At this point, Jin came up with an approach from a different angle.
"Your Highness, do you know the properties of a sphere?
"Properties?
"Yes, I do. ......Yes, first of all, think of a <>.
"A circle ......."
Jin nods and chews as he explains.
"A circle is a collection of points equidistant from its <, ...... that is, a figure enclosed by a line."
"Yes, that's right!"
"Then what about a ? ...... sphere is also a shape bounded by a collection of points equidistant from the center ...... plane."
"Ah, yes!"
Ernst nodded his head in agreement.
"Let's try to imagine it like that. ......<>!"
This time, it formed a beautiful sphere without any problem.
"It's done! We did it, Jin-sensei!
"Well done, Your Highness."
And so Ernst Shoro took his first step.
Ernst Shoro took his first step.
"What? I'm going to see Dr. Jin again today!
Ernst Shoro's voice echoed in a room in the palace.
"No, Your Highness. For the time being, I'll be touring the countryside."
