Breakthrough with the Forbidden Master

"Anyway, let's end this fast!"

A collection of problems made by Sadiz given as punishment. I decided to sit down at my desk and get started, feeling depressed.

"Ho. "I'll do it for the time being ..." "Sadis gets angry when I don't do it ... if she hates me ... I'm in trouble ..." "... Hey, don't shut up. No, yeah, well ... it's a new thing for the tone and attitude

The Great Demon King who peeped into me as if I was impressed somewhere to obey Sadis. I exchanged a few words with Tekitou and I immediately focused on the magic math problem.

“… Um… I disassembled …… substitute here…”

Saddis's original problem, which is a little more difficult than the ones in the Academy class. Careless mistakes are really fatal because of the complicated formulas. Sadis never gives a "partial point" that would have been obtained if the answer was wrong but the process was not wrong. Since it only determines whether the answer is correct or incorrect, it takes time to check.

"Huh ... it's a mathematical problem ..."

The Great Demon King seemed to be free and looked into the problem I was solving. Then, looking at my answer, Daimaou ...

"... Hmm ... Basic academic ability seems to be much better than his father."

I was shaken by the shock of squeezing the pen I had.

"Well ... what ... what? Is something wrong? Hey guys are single-celled idiots who don't have decent academic achievement no matter how they look at them 』

It was the first time I was told I was better than my father. Indeed, he has heard that during the Academy he was not good at classrooms. However, I had never said "excellent" by my father. He was told only a subtle praise saying "better than his father." That's why I was confused by the word "better than father".

"Well, once you solve this formula, it doesn't help you in the real world or in magic research ..." "tsu ..." "Even if you use it, it's only a test to make a difference in academic ability ... It means studying just for the exam. "

Everybody once thought, "What is this useful thing to remember?" The Great Demon King himself cut off the answer, saying, "It is useless."

"what? You're drooping and your hand is stopped, right? "Who's to blame ..."

What did I do for this ... suddenly, I became stupid. Because the self-proclaimed omnipotent and omnipotent are saying they are useless ...

"But you guys are inefficient. How do you do calculations that do not have the opportunity to use in such a long daily life?ろ う What is important is the answer? 』

Then, while sighing to me, my hand stopped, Daimaou, besides the meaninglessness of the problem, began to say that his method was "inefficient" in the first place.

"Inefficient?" Rather than doing each and every detail calculation, if you keep in mind the equations, it will be more efficient to do "automatic calculation" afterwards. "

I couldn't understand the words of Daimaou.

"Ji, automatic calculation? What's that?" "Oh, by the way ... you guys couldn't do that ..."

The Great Demon King nodded as if he was immediately convinced of my question. After a few moments of silence, the Great Demon King made an offer to me.

"Okay. If you can't go outside without finishing it ... I'll do a little more cooperation. "" Cooperation? What is it? っ て Will you solve it? " From now on, as I will instruct ... Create a contract magic circle for learning magic.

Is that a ritual to learn certain magic?

"Magic will increase the level of power and accuracy by training, but all beginner magic can not be mastered unless contracted by a magic circle. By the way, have you created a magic circle yourself? "Is it determined that you have contracted and learned the basic magic, wind, lightning, and soil attributes yourself? サ Sadith's gonna grow up by doing that work on his own ..." "Hmm ... then it would be fine. Okay ... draw a six-pointed star on the floor and cast the spells I say while elaborating the magic. "" ... I'm serious ... what's going on? "" It's more efficient "

Instructions to sign a magic contract while studying. If you want to finish early and go out, if you have time to do this, you should solve at least one problem. But still, Daimaou proposes that it is more efficient. Somehow I was interested in it.

"Chant it ..." "Wendowsma Aikurosofutoofaifabenburii ..."

As expected, it was a chanting that I had never heard before. In other words, this is Daimaou original ...?

"What the hell is it?"

If this was the original of the Great Demon King, I was a little excited like a brat without a handle. No matter how many of them are human enemies, it means that I can use the magic of the Great Demon King. And the magic ...

"It's an automatic calculation magic, Excel."

I haven't heard that. What kind of magic is it?

"Hmm ... well, good. Demon or snakes out ... sign a contract with me [Wendowsma Ai Kurosofuto Faith Benlii] ... The name of the power you seek is ... [Excell]!"

Well, it's been a long time since I signed a new spell. The peculiar pale light overflows, and the magic circles on the floor erode, wrap around, and come together to give me something new.

"... Is this okay?" "Sufficient"

The magic circle on the floor has vanished cleanly. This is a proof of learning a new magic, and it works.

"And ... what should I do now?" "Send the excel, envision the equation in your head and substitute the numbers. The chanting is the same ancient magic word as before. "" Wow, I understand ... Wendowsma Ai Kurosofuto Faith Benlii Exeiru!

Chanted. Now what happens? For a little bit, no, it is wrapped in a feeling that the inside of the head is smooth. This is similar to the feeling you feel when you are in good shape when using your head for calculations and memorization. In this situation, imagine the equations and substitute the numbers ... ?

“…… 4545072 ……?”

The moment you put a number in the equation you drew in your head, the number is in your head in an instant ... No way!

"It was automatically calculated ... that is the answer."

Yeah ...! ?

"What's good! I'm a fool, idiot, oh, that long calculation ... oh, me, now, in an instant?" All the calculations and functions divided into fine denominators and numerators in the equations, and if you even think of the formulas in your head, the answer will be automatically derived. ”“ T !? ”“ That was developed too much. It's

stupid! That's why a complicated calculation in such a moment ...

"Cho, wait a minute! Puy, now, let's check the magic as you unlock it."

There are incredible things. If this could be possible ... everything in the field of magic mathematics ... even the meaning of an exam ... really?

"Well ... the answer ... 4545072 ... the same." "This is another problem this time!

You don't have to do long calculations, beware of careless mistakes, and do many recalculations? Hey, that's it ...

"... 69 ... ko, really, really ... ha ha ..." Will it be efficient? "" Hahahahahaha! Phahahahahaha! The best! "

I rejoiced. No way, I didn't think I could learn such useful magic. This can be used. Rather, once you learn the equations, the rest is easy. Then, this princess only has magical mathematics ...?

But I hadn't noticed yet.

The magic and knowledge of the Great Demon King is not only useful in magic mathematics, but rather in this kind of introduction.
