--When Arx saw the magical silver expanding, he thought of a thermometer that used so-called inorganic mercury.


　If the altered magical silver expands in response to magical power, then it should be possible to measure the amount of magical power by sealing it in a glass tube, just like the mercury in a thermometer.
　If this idea is correct, the amount of magic power put into spells, which until now has relied on intuition, will become more accurate, and efficiency will improve dramatically.


　Arx, who had been dissatisfied with the current method of teaching magic, would not fail to see the light in this.
　On the day he came up with this idea, he was investigating the altered magical silver until dawn.
　As I proceeded with my research, I found out that when magic silver is exposed to hot magic released for a certain period of time, it changes into a substance that expands in response to the magic power.


　This result convinced me. He was convinced that he could make a thermometer to measure temperature and a magic meter to measure magic power.
　Early in the morning, Arx visited Crabbe's house.
　He told the guard guarding the gate of the mansion that he had an urgent matter to attend to, and was immediately connected to Crabbe.


　He had just woken up, and as soon as he entered the parlor, he gave a huge yawn.


　He had ...... long silver hair and tanned skin reminiscent of a Latin man in a man's world. He has burn marks all over his body, including thick arms, humped shoulders, and a thick chest plate. At the moment, he is dressed in a black tank top and long pants, a comfortable look.


　The first thing I did was to apologize and bow to him.


"Uncle. Good morning, sir. I apologize for barging in on you so early in the morning.

You're awfully early today... and you've got dark circles under your eyes.

I was up late last night.


　I'm not sure what to do, but I'm sure I'll be able to do it.


I'm not sure what to do, but I'm sure I'll be able to do it.　You're not going to grow up with a woman's face and a small frame.

"Ugh. ......


　Crabbe uses his thick fingers to ruffle my forehead.
　I was at a loss for words when he said the thing that was bothering me the most.


So, what's going on?　What's wrong with you? You're not supposed to be here at this hour, are you?　Did you get kicked out?


　Crabbe's face changed from sleepy to serious. If that's the case, is he going to go yell at them?


No, I'm not going to kick him out, that's for sure.

But you know what?　In the event that you've got a lot of money to spend, you'll be able to take advantage of it.


　That's true. In the event you've got a lot of money, you'll be able to use it to make a lot of money. However, this is because she has been a child until now, and now that she is taking an active role in everything, she is becoming more and more noticeable.


　I'm not sure what to do, but I'm sure I'll be able to do it.


I'll keep that in mind.

I'll keep that in mind. I'll take care of it. I'll adopt you.


　My uncle is as dependable as ever.


Please take care of him.

Yeah. I'll take care of it. There won't be one or two of us. Hahaha!


　While I was thinking about Crabbe, I also thought about his family.


You have a daughter, don't you, Uncle?

Yes, she's from Sapphireburg, and she's over there with her mother.


　Sapphireburg is a small country southwest of the Kingdom of Rynor, where we live.
　Its territory is as small as the kingdom's aristocracy, and it faces the kingdom, the empire, and the maritime states to the south, making it a dangerous place, but its borders are protected by a steep land, so it has not been invaded by other countries.


　It is said that Crabbe, taking advantage of his high position, sometimes goes there to show his face for inspection.


　Anyway, I should get down to business, so I straightened up.


I have a special favor to ask your uncle today.

What is it?　What is it? Are you asking for money?

No, sir. ...... No, I'm talking about spending money.

Huh?　So?

Well, I was wondering if you could make me one of these.


　He took out a piece of paper from his bag.
　He drew a picture of the parts needed to make a magic meter, and added an explanation.
　Crabbe picked it up and looked at it closely.


"A wooden frame, and this is a glass tube?　What the hell do you want with that thing?

"I'm going to try something. What do you think?　Can you get it for me?


　I asked Crabbe to get it for me, because I didn't have the connections to get it myself.
　I also thought it was necessary to consult with my uncle first because of what I was going to make.
　Of course, I would tell him what I was going to make after it was finished.


He said, "Well, whatever. Just make a few of these according to the instructions on the ...... paper, okay?

"Yes!

Okay. But things are things. ...... It's gonna take a while, okay?

No problem. I'll take care of it.


　...... A short time later, the package arrived at Raytheft's house.


　Some glass tubes reminiscent of thermometers, and a wooden frame for stacking them and comparing them with the scale.
　As for the altered magical silver, we have already prepared it ourselves.


　All you have to do is cast a spell to create a vacuum inside the glass tube and use a spell to move the altered magic silver inside the glass tube. .......


I'm still reacting to magic. ......


　If you use magic nearby, the altered magical silver will react to the magic power and expand, making it difficult to move.
　I know it's the same as a thermometer, but you have to create a vacuum inside the glass tube.


I didn't check how to make the thermometer, though.


　Buried in himself, he went back to his memory, but there was no trace of the process of making the thermometer.
　If I could find out, it would help me make one, but what I don't know, I can't help.
　After much effort and trial and error in deciding which spell to use, the altered magical silver was eventually placed inside the glass tube.


　The only question now is whether or not it will react to external magical power even if it is inside the glass tube.


"Please expand .......


　With a wish, I released the magic power.
　Then, the altered magic silver inside the glass tube moved .......


And it's done. ......!


　Immediately, I felt a sense of accomplishment, and my body suddenly relaxed.
　The prototype magic power meter was complete. With this, I can measure the amount of magic power in detail. Then you can calculate the amount of magic you need to put into the words and phrases used in the spell.


I did it ......!　I'm making progress with my magic!　Super progress!


　I can't contain my joy and start flying around the room.
　Even though it was originally the result of chance, I was able to achieve a solid result by myself.
　The joy is palpable. I can't help but jump for joy.
　It's only been two years since I was disinherited, but this is the first step.
　This is the first step for me to look back at my parents who scorned me and called me incompetent.
　I'm going to use this to become a mage who can use various kinds of magic.


　...... Before I can do that, I'll have to tell Crabbe about the results, of course, but I'll also have to make some improvements to make it even easier to use.


The first thing you need to do is to create and perfect a numerical standard. The scale, the amount of hot magic power exposed to magic silver, and ...... well, well, well, I'm getting really excited!


　I'm so excited, I can't help but mix my words with the words of the man's world.
　Then I pull out a ruler from storage.
　If it is to be used as a measuring instrument, the unit of measure must first be determined.


　Let's say that the total amount of magic power used in the general magic of 【Movement】is 10, and the unit name should be 【Mana】. In addition, in order to measure the amount in detail, we should prepare a number of units with different ratios of exposure to hot magic.


　The more I thought about it, the more I realized that I still had a lot of work to do.
　In the end, I stayed up all night to work on research and development.
