I'm tough with people.

Especially if you're running with romantic feelings.

All Isaac has ever dealt with was an adult.

They were popping out the actions they were supposed to take on the damage account and making decisions they thought were reasonable as nobles.

But Amanda's not.

She follows her emotions and pushes forward without fear of failure.

Besides, he didn't try to run out on just one of himself, and he also spoke to Loretta and Judith.

Because of that, I couldn't even push away "I don't like people trying to run out".

I don't know if it's calculated behavior or intuitive behavior.

But in any case, it was a difficult course of action for Isaac.

"How can I get her to give up?" It makes me feel heavy.

I dropped my shoulder and went home.

Isaac returning home can be told that Sieghardt will be here shortly.

This is what I was hearing yesterday.

Randolph is inviting me on the road to the Wang capital to talk about the grenade.

Get dressed and wait for his arrival while playing Kendra's opponent with Lisa.

Eventually Sieghardt brought the two offerings.

Isaac welcomes him with Randolph.

"Hey, long time no see"

Long time no see.

But Sieghardt seems to be in a diagonal mood.

I look at Isaac with grudging eyes.

"... what's wrong?

"What's the matter..."

I don't know why I'm upset. Give Isaac the look of "incredible".

"I'm talking about the flight test site! If you were going to make something that looks so interesting, you wouldn't have gone back to the country!

To match his words, the Dwarves who were accompanying him cloud his expression as well.

I don't expose my emotions like Sieghardt, but I guess they want me to invite them too.

Seeing their reaction, Isaac remembered what he once said.

Oh, if you want to make something new, let me help you.

I used to be threatened by a Dwarf who works for the embassy, "If you don't let me help you, I'll cry like a maiden on your chest".

Sieghardt probably wanted to make a hang glider from the start too.

"You asked Sieghardt to make something new. It's not like there was anything there. Just fix your mood."

"I should have helped the plane no matter what you think..."

"Well, well, not that Isaac was offended either."

Randolph scolds the disgruntled Sieghardt.

He also accompanied his escort until he came to Wang Capital, so he is already familiar with his face.

Even the Dwarf opponent spoke naturally, without tension, in the shape of an adult who could deceive a child.

"That's right. I just wanted to show you the finished product and surprise you. The plane still has room for development. We can do this together now."

"I may be... I can't stand it when I hear you're already in the process of putting people on board and flying. When I heard from the embassy staff, I thought I'd run the horse."

"I'm glad that's all you're looking forward to, but I'm going to show it off at a cultural festival, so why don't you wait a little longer?

"I can't, I'm still holding back my desire to get to the test site. As much as I would have called it off if I had other plans. I'll follow the embassy staff tomorrow and give them a tour in the morning."

Sieghardt was still showing how he was going to rush out.

If that's all you're grasping at, you can also count on cooperation, such as support for supplies, in times of rebellion.

Plus I don't risk being attacked from behind, so I'm just thankful I'm not an enemy.

"Okay. If you can't stand it, you can't help it. But don't get on it yet. You can't treat him if he breaks his neck bone and dies instantly. I want you to act with a sense of being a dignitary in another country."

"... I'm fine. It's awkward."

Sieghardt's reply was untrustworthy.

Although Isaac thought, "You're going to say you want to ride a hang glider," he replied that he knew who he was, so I can't say any more.

I just had to believe it for once.

At the end of the reunion greeting, guide the Sieghardts to the reception room.

Because the content of the story is the content, when the tea was prepared, people paid for it.

"I invited Lord Sieghardt today because I wanted to tell Isaac. The destructive power of new weapons."

Randolph opened his mouth first.

He puts a bunch of paper in front of Isaac.

The paper depicts a painting of armor.

And a black dot was also drawn.

"That black dot is where the iron sphere made its hole. I am sure it broke a lot of armor but it wasn't in vain. Exactly. You won't be able to defeat ten people in one shot, but I think you can defeat five if you throw them inside a dense formation. The noise is loud and surprising, so the movement stops. Besides, the formation would disrupt, so it would affect more than the number of soldiers injured. Grenades are amazing. I think I can fight a lot of them."

Randolph, who was present in the experiment, can't seem to hide his excitement.

Isaac also gets tense as he goes on to read the report.

Sometimes it hit my head and torso, but what exploded on the ground hit my feet a lot.

This would push you through with a "weapon that will cause you to get hurt but not kill" even if the results are known to Dwarves and Elves.

Even legs have the potential for blood loss, but you don't need to teach them that much.

"Looks like some of them exploded in the air. This is good because it's still overhead on the target, but you have to be safe to not explode before you throw it."

"That's not a problem. Not everyone spins and throws the same by the time they throw. It was when I was adjusting the length of the fuse line to suit each person. Now that we've found the length of the fuse that we can afford to throw, there's no way we're going to explode on hand."

Isaac wondered if the soldier would blow himself up, but it looks like he's already dealt with it.

"I know how hard it is to get the length of the fuse wire wrong. I've been coaching you."

Sieghardt tells me it's because of guidance from the Dwarf side.

Even they wanted to avoid harm to humans with what they delivered.

"Thanks, that'll help. Now, did Neuizen give you permission to export?

"Naturally, some objected. But grenades are not the only thing humans use. We can use it against humans when we are outnumbered. That's what I convinced you to do. You can make a real thing out of human money and try it, so your grievances were minimal."

This human fund was the license fee Isaac was getting.

The Rudolph Chamber of Commerce, run by Sieghardt's grandfather, is collecting license fees on behalf of me in Neueisen.

The funds are entrusted to Sieghardt for operation.

The cost of developing and producing grenades was getting them out of there.

The Dwarf side is getting free know-how on new weapons.

It would be true that there was less dissatisfaction.

However, when it comes to the act of passing powerful weapons against humans, there may have been someone with a sense of repentance.

I can only hope that the study of airplane relations will alleviate Dwarf's mistrust.

"How many can you hand over?

"Five hundred rounds a month."

"That's not much... I want my soldiers to practice, so I want ten times that."

"I guess that's a little harsh"

Sieghardt looks sinister.

He put the bag in front of Isaac on your dwarf with his eyes open.

"What's this?

"It's the result of low production."

- Causes of low production.

When they say that, they get scared to look at the contents of the bag.

But it doesn't seem like a situation where you can say "scared" and run away.

Reluctantly, Isaac peeks inside with a zusili and a heavy bag.

"Iron Ball?

Isaac puts his hand in the bag and takes out about 2 cm of iron balls.

Except that it was made of iron, which was a beautiful sphere like a beaver ball.

But I don't see why this is responsible for the low number of productions.

"Yes, that iron ball is what caused it. I really can't make the numbers. And they don't like to make iron balls."

"What, isn't this kind of casting?

"It's a cast. But I'll stick to the finish. Brush it up until it's a beautiful ball. I can't make the numbers because of that."

"Did you tell him you were a disposable mass product?

"I'm talking to you. Still, craftsmen are obsessed."

Regardless of Sieghardt, who aspires to be a merchant, he can't help himself to the Dwarves of artisanal skin, albeit mass-produced.

Isaac rolls an iron ball on his desk.

It doesn't flutter, so it seems unlimited close to a true circle.

It's a fine thing to create something like this by hand, not relying on machines.

However, attention is not required for disposable mass production for which a number is required.

(Trouble...... If you think about what you use for training, it's not enough at all)

The fastest, in April, will be a war.

At 500 rounds per month, only about 2,000 rounds will be available by April.

If used in training, it would be even less.

It can only be used for the first blow on the battlefield.

This was a huge miscalculation.

"We have other jobs, and we can't just let them make iron balls. So I decided to ask artisans everywhere to do their jobs and make them little by little. Production in one place is small, but if craftsmen across the country make it as a penny between jobs, it will be quite a number. I think I can make a thousand rounds a month after next month."

"Good for you. I'm counting on you to make as much as you can."

Isaac gives a horrible look.

Five hundred rounds a month and a thousand rounds make a big difference.

There is a huge difference between a blow to the opening, a blow on a stubborn occasion, and whether it can be used twice.

I just prayed that Sieghardt's men in the country would do their best.

(Stop talking..., don't you want it)

I never bothered to stop talking about grenades.

Randolph has also found it to be an important new weapon to the extent of paying for it.

You won't talk bella besides your body.

So does Sieghardt.

He shouldn't talk other than Dwarves.

If you pay close attention, they'll take it like you're saying, "I don't trust you," and you'll be in a bad mood.

I didn't feel the need to go out of my way to say "don't tell anyone".

"Still, this iron ball is amazing. It's dangerous if it's iron, but if it's made of wood, it's going to sell with toys for kids."

Isaac takes some iron balls out on his desk.

I don't do it because it seems painful to bounce it off with my fingers like it was the beginning, but it's just right for rolling and playing.

But even if it's small, it's an iron ball, so it's dangerous when a kid throws it or something.

I just wanted to give it to Kendra, but I decided to stop thinking about safety.

(... that? I think I can think of something.)

Taking the iron ball and moving it in your hand like a relaxing ball stimulates the memory of previous life.

Gradually it came up with what to make.

"Did you come up with something?

I was looking at Isaac, whom Sieghardt thought intriguingly.

Isaac smiles back at him.

"Yeah, well...... If you use it for your car bearings, it will rotate smoothly... it should. Somebody!

Isaac speaks outside the door.

Then a servant knocked and then came in.

"Can you bring me some tamarind from the music room?

"Tambalin......, is it?

"Yes, tamarind. I like the round ones with lots of ringing ones."

Isaac shows by doing the trick of ringing tamarind with his hands.

So the servant understood that Isaac really wanted tamarind.

"Yes, sir."

The servant put his inner neck around him and said, "Is there tamarind in this place?" but I honestly followed orders without putting them on my face.

"Tambalyn? Are you gonna sing me a song?

Sieghardt, I said, doesn't really think about that either.

I was wondering if I would do something using an iron ball.

"If I'd rather hear a song than make something new, I would. Well, let's wait till we bring it."

That being said, Isaac begins to ask about the results of the grenade experiments and so on.

As a result, I am convinced that, although less powerful than I had imagined, it seems sufficient for use in war.

Eventually the door was knocked and a servant brought tamarind.

"Thank you. You can back off."

I beg your pardon.

The servant honestly followed orders, but inside he said, "How do you use that?" He left the room with the thought of being pulled behind his hair.

"I want you to look at the cymbal part of tamarind because you think it's an iron ball."

Isaac placed the tamarind vertically on his desk and slowly rotated it by hand to show it.

"Can you expect a smooth rotation by using the iron ball between the carriage and the car bearings? I think the less surfaces you touch, the less friction you get."

What Isaac came up with was a bearing.

Having seen an iron sphere close to the true circle, it occurred to me that it could be used.

If the bearings are complete, the weight of the bicycle pedals should also be able to be eliminated.

"Hmm, it would be awesome if I could do that... How do you fix it?

"... let's think about that together. Aren't things fun to try and make mistakes?

"You sure do! Think together!

Sieghardt gave a full smile.

Usually Isaac shows the finished shape, so I was happy to get involved from the start.

"You all have your hands free and it would be helpful if you could help me out in your spare time"

"Oh, please! Then I will be happy to help!

The Dwarves who were accompanying Sieghardt were delighted.

Even though Isaac also knows how the bearings work, he doesn't know how they're fixed.

It was to be welcomed that more people would study with us.

And bearings aren't the only purpose.

"But it's also important that we don't get distracted by new things and improve the quality of what we have now. Planes will have to be developed from now on, and we will be studying them for ten or twenty years. That's about it to make a new product, and from now on, let's slowly calm down and aim to improve the quality one by one."

- I'm running out of stuff I can think of.

That's why I wanted to take it to the "Let's do our best to improve quality from now on" story.

Collaborative research is important for that.

If it is a product that we have struggled to develop, we should also be more conscious of working to improve the quality.

Isaac strongly hoped that he would be less willing to expect something new from Sieghardt.
