The Best Assassin, Incarnated into a Different World's Aristocrat

This will be the last time Dia teaches me magic, and I will be picked up in the evening.

I was trying to gather our research results.

That's magic to make alloys.

Until now, in the magic of producing metals, only monoelemental metals could be made, and alloys could not be made.

However, it succeeded in mixing multiple metals by modifying the surgical formula of material deformation.

That means a lot.

For example, there is a metal called titanium.

The weight is about 60% while having roughly the same hardness as iron. The melting point is very high and resistant to heat.

And even better corrosion resistance. It's a good metal that won't rust and corrode.

... but I'm not comfortable with the fact that hardness is only equivalent to iron if it's the standard of the world at first sight here anyway. Or if the stiffer metal is non-stick and brittle, or heavier and better than titanium, lean your neck.

However, with titanium alloy, the advantages can be increased in hardness and cut flavor as is.

Specifically, add vanadium and aluminium. By doing so, it becomes beta-titanium.

Even though the hardness is nearly double, it is light, resistant to degradation and sticky. It becomes such a dreamy material.β titanium is even called high end as a knife if used in harsh environments.

The titanium, vanadium, and aluminum created by magic in front of you are magically united.

Success. Titanium alloy, beta-titanium complete as desired.

further deform it and create a knife. Wrap the skin around the patterned area and give it to Dia.

"Dia, this is our magic work."

Dia slashed a tree that was nearby.

"Light, what a cut to that. Now if you make and distribute the sword, the soldiers' fighting power is going to go up a step."

That's just an aristocratic warrant lady, with a different perspective than a normal girl. And I guess the fact that the idea comes out exactly means that her territory is a battle-conscious environment from day to day.

"Maybe we should stop doing that. It won't be a fuss for us to sneak up on, but if we mass produce it and give it to people, it will be an extra spark... worst of all, we can keep making it out of slaves in the country for the rest of our lives"

Anyway, it's time for poor quality iron to dominate weapons.

Everyone wants this if they know they can make such a good sword.

I used to describe a knife with raised tension and pure titanium as a demon sword, but that was a little overrated.

But this is the true Devil's Sword.

"Maybe if you ask me...... but not if it's just the Knights you can trust, just the three of you? Everyone has a very hard mouth, and I want you to use a good weapon.... don't die on the battlefield"

Don't die. I want a strong weapon for my loved ones to survive.... I know how that feels, and don't be a little jealous of the knights who seem that far to Dia.

"No matter how trustworthy the knights are, they have someone they won't lie to. Secrets definitely leak.... right, if you can hide what you made out of witchcraft and give me your sword. We've talked about this before, but the new magic we both made is to keep it a secret. [Shooting] also only when life is in danger if you don't use it"

"Yeah, you will!

Dia snorts, imitates me and chants, but fails to smell the alloy.

"That, why?"

"Probably not enough power in the image. However, unlike just creating an alloy, the image around it is important to see how the metals change from one another and how they are completed."

In the case of deformation, the image of the operator becomes important instead of the out-of-the-box sorcery. Unlike deformations that just change shape, it is necessary to understand chemistry if alloys are to be made.

"I can't do that. I don't know why it would be strong metal if I mixed it..."

"I'd love to teach you, but it's going to be a very long story because it's from the basics of physics and materials. Right, it'll take a month."

A month is a story based on the assumption that you have as much brain as Dia. If it's not Dia, that five-fold sees the period.

"Ugh, today, to go home"

"What's the extension?

"... if you can, I'm doing it, and I'm asking you to do everything. But I couldn't. Even I still want to make magic with Lug."

I'm a little glad you said that.

... so let's do the service.

Titanium alloys were further produced, they were processed and three swords made. Good slashing taste, durable, light sword. Processing to mainstream straight swords in this country.

Besides, I also put a sheath on my sword. It's just titanium because you don't need a cut over there.

"The knife and three swords I just gave you are souvenirs. Let's think of an excuse for how we got these guys. Maybe ask your father to cooperate. Even Dia's father would be suspicious if he brought the Devil's Sword back from the territory of Towahade, and would probably contact his father. My daughter stole it on her own."

"Right. I think maybe your father would.... I'm so glad you made a sword and took so much care of it. Lug's a good kid."

Embrace the three swords with joy.

It is magical to be able to hold three swords together that weigh as much as 60% of iron.

A certain amount of magic is always covering your body, even if you are conscious and do not put together magic.

"... this is a thank you. If Dia hadn't been my master, I wouldn't have been able to use magic so well. Thanks."

"I'm the one to thank you. If I hadn't met Lug, I never would have thought of making magic. I could have liked magic a lot better than before. I'll make lots of new magic when I get home. When we meet again, Lug will write the whole ceremony."

"That sounds tough. But let me do it. I look forward to Dia's magic."

I'm sure you'll make interesting magic with a completely different idea than mine.

Knowing that makes me even stronger.

"It's a bad idea to just teach me, so tell me about the magic Lug made."

"Right, I'll make magic that will surprise Dia...... you have the eleventh magic Dia remembered before. With that, we could make magic four hundred times more powerful than [shelling]."

There are still plenty of challenges at the theoretical stage, but if it is completed, it will be feasible with my instantaneous magic release, and strategic magic four hundred times more powerful than [shelling] will be completed.

"... that even transcends ritual magic, which is done by hundreds of people already, right? But I'm so excited. I met Lug and I might have been excited for the rest of my life. I definitely don't want it to end today. So promise it won't end today"

Dia has been putting out her fingers.

The two of us hold our fingers together and Dia laughs.

I thought it was cute.

I'm sure this is the kind of emotion you didn't know about at first sight, or admiration.

I want to be with you, my chest tightens with a breakup.

Let's get these emotions one at a time in our second life.

Because that must be the normal happiness I sought.

◇

It was an early dinner in the evening.

It's Dia's farewell party.

There's a line of treats my mother and I made sticking together. I have a gratin that she likes the most in two weeks, and exactly Dia is spooning the gratin for a crisp, mellow smile.

"Dear Dear Dia, thank you for raising my son so far"

"I have my powers, too, because Lug is a genius. I've never been jealous of a child before."

"Does Lug also have a talent for witchcraft? You have a high nose."

My father laughs in a good mood and tilts the wine.

"Um, Uncle Kian, actually, when I was exploring the mountains with Lug, I picked up my sword. Lug told me I could make it a souvenir, but can I really bring it home?

Since then, the two of us have discussed it and decided to tell my father with these muscles.

"Well, there's a sword in the mountains. Can I borrow it for a second?

"Yes, go ahead"

Pulling the titanium alloy sword received from Dia out of her sheath, my father gently waves and nods.

My father would spot the true value of the Devil's Sword made of beta-titanium with that alone.

"Well, you had something interesting buried in the mountains.... and it looks like it's still buried in the mountains. It could be buried in another mountain."

The second half of the intonation is a little special.

Receive the intent and I'll respond.

"Father, we're still buried in that mountain. Next time, let's look. But the only thing that's buried is that mountain. I assure you."

"Right, just that mountain? Then fine. You should give it to someone important to Dear Dia."

... By the way, when I translate the current one, my father is convinced that I made it, and he asks me if I can make the same one, and if I'm the only one who can make it.

So I replied that I could make it, and I was the only one who could make it.

Only my father won't hide it because he can't deceive me no matter what.

Besides, there was a calculation that if this sword had a problem going to Vicone, my father would stop it.

"Wow, I can't believe Lug would give a girl a gift. Shit, this one. Dia, you're so cute."

"... Mother, don't do that"

"Hehe, I won't stop. Because if you do, Lug, I've been getting more and more busy lately, and this is when I can interact with you. Dia, are you willing to be our kid?

"Uh, shit, you know, when it does, I think it's nice"

Dia lit up and nagged. To Dia's words, my mother says a lot more on track.

It's not like I don't feel that way either.

Still a kid, but sooner or later, Dia...

Dia will grow up to be an absolute beauty, and she's excellent. She and I are much more in the process of developing new sorcery.

Besides, I need my own strength to kill braves, but that's not enough.

I have a team. I don't know what I could do alone.

I want Dia for that too.

"I think it's too soon for me. Anyway, it's good to have friends with Lug. I was worried about her because she wouldn't go out there."

"Father, then you sound like I'm a dark child."

It's just a reflection. I spend my time other than training and studying, even caged in a study or practicing voluntarily.

Personal specs were up, but there may be problems forming communication skills.

For free time in the future, go outside and make friends with kids your age.

"Yes! I'll be your friend to Lug. I'll send you a letter when I get back to the realm, and I'll see you as soon as I can."

My father and mother seem to smile, looking at me and Dia.

It's a little awkward.

This warmth is real, but it won't be the only one.

I've been thinking about this for the past two weeks.

Meaning my father called Dia. Indeed, Dia was excellent as a master. But you can't just call that bomb that my father is a nobleman in another country for that reason. There's something worth the risk.

It makes sense that you let me and Dia meet at this time to get along.

Thus, the last supper was over.

Afterwards, a servant shows up for tea and tells him that he's picked up.

We're going outside.

Dia rides the carriage.

Slowly the carriage runs out.

"It was so, so much fun! 'Cause I'll definitely be back!

Face out the window, Dia screams.

"Oh, I'm waiting, too"

"And then, this, take it! Don't forget about me!

That's what I said, I've always thrown a pendant hanging from my neck.

A necklace with clear crystals and purple magic shines in the crystals.

I know because I saw everything next door. This is Dia's magic.

Did you give me the foul stone with magic? You said you could never give it to anyone else in your territory.

"I'll never forget it!

Scream.

"Then I promise you'll listen to everything you say back then, please now. If, when I really wanted to see Lug, I would definitely rush!

I'm saying pretty unscrupulous.

Still, I'm not lost.

"I promise! 'Cause I'll be sure to rush then!

A little while later, I couldn't see the carriage.

I got magic the last two weeks and further developed it.

But it was time to get something bigger than that.

Come on, let's keep it up.

The next time we see each other, we have to make enough magic to surprise Dia.

... Well, when shall I go see him? Normally, I haven't had a chance to meet Dia in years.

I don't like that. I need a regular exchange of views with Dia for the study of witchcraft... and I miss her too much.

After examination, it was roughly 320 km over two mountains to Vicone territory.

Long distance travel, it's not impossible if I'm also the one who goes through the border secretly, enters Vicone territory unnoticed by anyone, sneaks into the mansion and meets Dia. That would be the best training I've ever had as an assassin.

With a little more strength, let's go see Dia when the training is ready.

For the first time, it's an idea I never would have. But that's what I like about myself. I'm not just a tool to obey someone's orders. Do what you want.
