“Next, it’s the explanation about humans with high inhibition value .

To tell you the truth, I don’t know much about this field .

I myself also have three rainbows, which means I’m on the low side . ”

Gilbert started talking while carefully wiping the blackboard .

He occasionally stopped as he tried to write something with the chalk .

It seemed that what he wanted to talk about was not well-organized in his mind .

“The higher the inhibition value, the greater the feeling of ‘distortion’ and ‘disturbance’ when creating a wand .

Such people have to spend a considerable amount of time to create wands .

The burden of mental concentration on spell-building is also ridiculously high . ”

Gilbert’s hand which was holding the chalk started to slide on the blackboard making brisk sounds .

Ooh, the lecture had resumed .

When I thought so, he started to drew a dancing golem .

He didn’t know what he should write, I understood that .

“Generally speaking, suppose that there was a one-rainbow alchemist, the generally known lowest inhibition value, he could charge magic for an hour .

It depends on their training, but it goes around like this; two hours for four-rainbows, three hours for five-rainbows, so six hours is the standard for six-rainbows alchemist as the maximum value .

So, that’s right……since I have never heard of seven-rainbows, this is only a theory, but it would take 12 hours or more……”

Gilbert drew two rows on the blackboard as if he remembered something .

The number of the rainbow in the upper row, and the required time in the lower row .

Gilbert’s hand which was writing the numbers in order stopped on the number seven .

He thought for a while and put the chalk on the blank field .

Even if the seven-rainbows would be twice as much as the six-rainbows, that would be 6 to 12 times more than the required time of a general creator .

It was natural that I had never succeeded in making wands, as the necessary concentration power increased accordingly .

It was a very painful penalty as an alchemy .

“Speaking of which, even though I tried to build a spell, it quickly got distorted and broke . ”

“You’d better give up on building wands .

This is only a speculation, but it seems that it is the same as how the zero inhibition value cannot use a wand .

I think it’s safe to a.s.sume that seven-rainbows mean you cannot make a wand . ”

“Aah, I heard that you can’t make a wand, but, no way, you won’t be able to make a wand in your life time?

That kind of thing, that’s too sad……”

Harold looked at me with pitiful eyes .

Even though he should have the same extreme and rare const.i.tution as me .

“Hmm, if you want to build a spell no matter what, it might be easier to learn mages’ art . ”

“Eh, can I really use mages’ spells?”

“Aah, let me explain a bit . ”

Gilbert turned towards the blackboard and drew a larger human figure .

The figure had a staff on his left hand and a wand on his right hand, then he drew a circle on both sides .

“There is a hole to convert external magical power and a hole to take external magical power as it is .

Well, rather than a hole, it is a port . ”

Gilbert drew two arrows from the circles

drawn in the human figure on the blackboard .

On the left, the arrow briefly went to the spiral on the stomach and ended on the staff .

On the right, the arrow smoothly curved and led to the wand directly .

“Just as a port is built at the mouth of the river of each branch, these two ports are in different places .

If you compare it to a s.h.i.+p, the mage’s port is the one that processes the goods temporarily in port town and carries them to inland .

The alchemist’s port goes directly from the river and carries it to inland .

If there is nothing wrong with the conversion port, there is a possibility that Hafan’s magic can be used .

Although if you start at your age, you will need a considerable effort . ”

“I see, so that’s how it is . ”

I looked at the ill.u.s.tration drawn on the blackboard .

If that was the only way to do it, I should also consider about becoming a mage .

But, I was born in the family of alchemists, so I didn’t want to give up .

“Anyway, the seven-rainbows Ojou-san should be the exception of all exceptions, it is an unthinkable const.i.tution .

Although the zero-rainbow creators have appeared spa.r.s.ely in the long history, this is the first time I see someone with seven rainbows .

How advantageous it is when using a wand, I can’t even estimate it . ”

Eh, ‘advantageous’?

Perhaps similar to Harold, I had a specialized talent in using wands even if I couldn’t make wands?

“Well~, Ojou-san’s definite employment seems to have been decided . ”

“What do you mean . Aniki?”

“If we trained Ojou-san properly and thrust her onto a strong s.h.i.+p, it will become a battles.h.i.+p .

It is said that the wand’s bombardment released by alchemists with five or more rainbows is a destructive force that even beat the athanor cannons .

They don’t have the trouble of reloading and they are also more flexible .

If it was someone with seven-rainbows, they won’t get tired no matter how much they use a wand, so wouldn’t they become the ultimate artillery battery?”

“Eh, what, that’s amazing~!! Congratulations, Erica!”

Harold shook my shoulders out of excitement .

Eh, but Gilbert-san, what did you mean encouraging little girls like me to work for the army?

“Do they even have a position like that?”

“Alchemists that are on the battles.h.i.+p use spells of extraordinary magic .

I don’t know exactly because it is a military secret, but it is said that if you don’t have more than five rainbows you won’t be able to serve in the military .

The famous example these days will be Duke of Aurelia, the Long-Armed Ernst .

It seems that he is a super long-range type, he would calculate the roundness of the stars and bombarding beyond the horizon .

In the naval battle against Gigantia, I heard that countless super large giants have been made into sea algae from outside the range of normal battles.h.i.+ps . ”

Certainly, Ernst-otousama’s characteristic skill was the extended range of his wands .

If such a ridiculous technique could be used, was he actually the same seven-rainbows as me?

No, Otou-sama should have been able to build and charge spells .

He should have about five or six rainbows .

“In the last war, some people seemed to use Evil Eye of Bolts to a great extent .

Using a special visual magic which they monopolized the manufacturing method,

method, they were able to aim an outrageously wide area simultaneously .

With Magic Missile that had its power expanded, it is said that each fleet could do wholesale arrest .

It seems that they were famous for their greed, and got territories that were part of the royal territory and a part of the southwest islands as the awards . ”

“Really . ”

“It was the one who was renowned as the most powerful alchemist during the era of Severe King Jean, with epithet Magic Missile, King Erik Aurelia .

With a dazzling translucent beautiful appearance, he was our cruel, arrogant, and unforgiving King .

It seems that the main offensive wands like Magic Missile were developed in his era . ”

“I see . ”

“Even if you can’t make yourself a wand, a cavalry alchemist will tailor lots of it for Ojou-san .

If you survive the war a couple of times, you will get some of the southwestern islands as your territory .

When you reach old age, you can manage farm in a tropical country . ”

“Uwah~, how nice!”

“That’s the dream, right~ . If only war happened again~ . ”

I didn’t understand why Harold and Gilbert were in favor of going on a battles.h.i.+p .

I wondered if all boys liked wars.h.i.+ps .

I apologize for having to tell you this, but I didn’t want the war to happen .

I felt like it would never be a bad thing if it didn’t happen .

Far from doing a meritorious deed, it seemed that I would die inadvertently before I became active in the military service .

“So, that’s why .

Why don’t you try special techniques like the one that cavalry alchemists use?”

“Is there a technique like that?”

“It seems to be a wand alteration .

It interferes directly with the spell at the time of the wand’s execution, extending the effective range or shooting it all together .

If it is true, it’s a dangerous technique similar to thrusting your hand into a furnace, but you have to force it with your high inhibitory ability .

I can only explain it roughly because I didn’t know much about it, but if it is the seven-rainbows Ojou-san, you might succeed in one shot unexpectedly . ”

“Oh, that’s great, Gilbert-aniki!”

The two of them took the initiative and were getting excited  by themselves .

The two had begun to clean up the things used for the lecture such as the blackboard and others as quickly as possible .

“Even if you said that……do we really don’t need to learn the theory first?”

“Nope, I don’t think it will be useful to teach you more theories .

Practical learning will be easier to understand . ”

“Isn’t it fine, Erica .

There are still many prototype wands, so go ahead and try using them . ”

It couldn’t be helped .

I reluctantly agreed to use another wand .

Along with Gilbert, the three of us moved to the test site .

Harold engraved letters for making golems on the ground once again .

“I will help too . ”

“Ooh, thank you!”

Since it wasn’t always possible to succeed with a single shot, there was not much to be done .

When the two of us finished writing the letters, Harold launched the golems .

More than thirty earth golems began to rise .

The over-all length was two meters approximately .

Because they would only become targets, I omitted the walking function and just made them stood at equal distance

equal distance from each other .

Harold handed me a new wand .

It was the Wand of Rain of Stone that I had used in the battle against Palug, Harold-style arrangement version .

“It creates countless jade fragments and is charged with spells to downpour in a wide scope .

It seems that there is a strange peculiarity in the material I used, so the realization time is a little short . ”

I remembered Onii-sama’s Wand of Rain of Stone .

It certainly seemed that it maintained its shape for about five minutes .

“Hey, Harold . How long does it generally take to materialize?”

“If it is pure substance materialization or matter creation, not a material transformation, even a moderately skilled creator wouldn’t take longer than 10 minutes .

If you use precious stones like jade and materialize a large ma.s.s each time, 5 minutes would be the limit .

I should be able to do it in about 4 minutes, but this wand is about 2 and half minutes . ”

I see . So Eduart-oniisama could go up to the five minutes limit .

As expected, Onii-sama .

A versatile cheat alchemist who also wasn’t an ordinary wandmaker .

“Well, let’s try it first . ”

I put on the gloves returned by Harold and shook the wand once .

A jade-colored magic circle formed over the aimed golems’ heads, and several pieces of sharp stone fragments that had formed were pouring down and pierced into the golems .

The time between the formation to the stone hail from Harold’s Rain of Stone felt shorter than Onii-sama’s .

In proportion to that, the range where it poured down was a little on the smaller side .

For the time being, it seemed there was no part where my power worked .

Gilbert, who was watching the situation, opened his mouth .

“Anyway, why don’t you try shooting them in one go?”

“Shooting them in one go, huh . What should I do?”

“Hmm, well, I don’t know anything concrete .

So, try to somehow forcibly pull out the spells from the wand with an image?”

Gilbert somewhat roughly told me the appropriate thing .

While holding the wand, I closed my eyes while feeling anxious for some reason .

There were lots of magic packed inside the wand in a form like gla.s.s beads .

As I shook the wand, I imagined taking all of those beads in one go .

Although it might be an illusion, I felt a sense of lots of beads rolling in the wand I held .

The image solidified .

“I’ll try it . ”

I shook the wand lightly .

“……Ah . ”

The magical beads in my image tumbled down all at once as soon as they stopped .

Countless magic circles s.h.i.+ning in jade green color covered the area over the golems’ heads .

It looked like roughly thirty magic circles formed all at once .

A moment of silence .

And then a roaring sound reverberated .

Soil dust blowed up and covered my vision .

After a while the roar stopped, and the dust subsided .

Every golem there was crushed and scattered about as a wreckage .

Most of the pulverized pieces turned back into lumps of soil, and there were also holes in a pattern like a honeycomb on the remaining fragments .

“Uooh~! What a destructive power! This is the true Rain of Stone!”

“I shot a lot all at once . Unexpectedly, all of them were

of them were shattered by one attack . ”

“……Scary, what is this, too scary!

However, you truly succeeded in your first attempt, as expected from the person with the rare seven rainbows .

Amazing, Ojou-san, if those were human opponents, wouldn’t they die immediately?”

That was troubling .

It was too exclusively for extermination warfare, the amount of this wand’s energy consumption was too much and it couldn’t be used in a friendly interpersonal match .

However, it might be an effective attack against the phantom beast .

It would be worth training .

“You are amazing . It is the most valuable guinea pig……I mean, sample . ”

With sparkling eyes, Harold gripped me with both hands .

He was rephrasing it hurriedly, but I heard 90% of his real intention .

(T-this guy……)

He had quite a mad scientist disposition to treat a girl of the same age as a guinea pig .

I refused to become a guinea pig .

“Yes, yes, thanks for that . ”

“Become my partner! No matter how you think about it, we are destined for each other!”

“Ha?”

“You cannot make a wand, but as a user Erica is unbeatable .

I cannot use a wand, but as a creator I am a genius .

These are talents that make up for each other! We are born partners!”

I certainly felt that our compatibilities seemed to be good .

But I didn’t live near Knot Reed, so I guessed it would be difficult to be a guinea pig as a pretext of a partner .

“I beg you!”

Hanging around the direction I turned away, Harold held my hand and asked .

Somehow, he looked like a healthy medium-sized fluffy dog .

What should I do .

I wanted to refuse the role of a guinea pig, but I didn’t want to hurt his feelings .

“Hey, hey, hey, Young Master . That way of saying is not good .

If you want to make advances, you have to think about the other party’s feelings, or you will be a nuisance . ”

“Such a thing, Aniki……”

Gilbert hit Harold’s shoulder and shrugged .

To that helping hand, I felt relieved . I was glad that there was an adult with a good judgment .

As Harold’s hands became loose, I pulled my hand out of his grasp .

I shouldn’t tell him the truth that I wasn’t very good at closing the distance suddenly .

There was the previously mentioned fraud case, so I wanted to keep a reasonable connection, but I also had trouble getting along well with others .

After I gave a moderate advice and evaded the destruction, I would like to fade out naturally .

“I guess the price estimation is about to end .

I am waiting for my company and I’d like to return to the shop, is that fine?”

“Ah, that’s right . You are a customer . ”

Harold suddenly raised his head .

Alright, it seemed that he was still in good spirits .

“Aah, Ojou-san is my old man’s customer, huh . ”

“If we don’t go back, that all-black mister will be worried . ”

“Well, then, Gilbert-san . Thank you for today . ”

“Hahaha, if we have other opportunities for a proper lecture, I will teach you about Alteration . ”

When I lowered my head, Gilbert laughed somewhat uncomfortably .

Gilbert waved his hand and went to see us off, and disappeared back to the depth of the Wunderkammer to hide from the shopkeeper .
