End of March.

Isaac was looking back at the past year.

- When I think I'm a sophomore, I'm suddenly caught up in a dueling noise.

- After that, I helped Judith and sent Michael to church.

- Once we created the balloon, we were somehow sent out to fight dragons, causing handkerchief disturbances.

- At the end of the sentence, I framed him for helping the killer who attacked Nicole.

It was a scattered year.

"I just hope the third grade has a good year," but I couldn't rest yet.

"Nothing new inventions? I've been looking forward to it."

Sieghardt was visiting the mansion with several Dwarves.

I'm staying in the King's Capital because of this, but I don't think Isaac will be happy to show me something new.

"You won't have a choice. Looks like you've been busy this year. Nevertheless, I've come all the way to Wang Du, and I'd like to see something rare."

Mathias tunes in to Sieghardt.

He had taken an elderly elf to see how Claude and Bridget were doing.

So we all had a flow to talk together, so we were all gathered together in the reception room.

Isaac was not alone, but balancing his face by having Randolph present.

"I've been busy this year so hey...... There's something left to think about, and Isaac shouldn't have been able to afford it. I was looking forward to it too, but you can't say you can't."

Randolph protects Isaac.

Because Isaac has been busy this past year, even from his point of view.

Among other things, I recognize that women's relationships that can be seen nearby are difficult problems that have not yet been solved.

Isaac can't afford to think about anything else.

"... no, I have a story on my mind"

"Do you have one!

- It was.

But I answer that I have the person.

Randolph, sheltered more than anyone else, was surprised.

Isaac said, "What is it?" I see my father as chilling.

But soon, he turned his gaze back on the Sieghardts, who had turned into sparkling eyes.

"But it's something I don't really want to show you. This is what Sieghardt was thinking of giving us the blueprints and samples when he left. I'm just wondering if I should show it to you because it's not like I can show it to anyone...... Perhaps we should talk to Mathias when they're around, rather than put the problem behind us."

"What kind of stuff is that?

It's classified as a weapon.

Isaac regretted answering Sieghardt's question.

Sieghardt apparently expected it and showed no special reaction.

But not the others.

- The weapon Isaac thought of.

Because when I found out about it, I blatantly looked at him and told him my heart without having to put it into words.

(Was it a failure? But we should talk about it... Oh, already. Judith's the reason you're lost.)

I'm sure you didn't have to know the consequences of fortune telling me.

But because I know the results, I don't know if I'm on the right path.

What Isaac himself had learned was more influential than what Judith had learned about the future.

But now we have to act.

I won't do anything. Rika is better.

"I said weapons, but not anti-dwarf or anti-elf. It's for humans. We also have anti-human weapons available for Dwarves. I'm trying to make sure there's nothing to spark the inter-ethnic war again. And it's something that can't be used without gunpowder, so unless Dwarf leaks the method of making gunpowder, use is restricted. Don't worry, it's not unlimited."

Though I said, "Don't worry," there's nothing to be relieved of.

So Isaac decided to show the real thing.

"Norman, get me Matt. And to bring samples of grenades."

"Yes, sir."

Isaac gives Norman instructions.

The Knights put their men in a missionary order, and samples of the grenades headed to get them themselves.

This sample is what Isaac has designated as important.

Because I couldn't touch anyone, so Norman had to go himself.

"I'll show you the real thing. What I'd like you to do is listen to me until the end. I don't want to cause any extra misunderstandings. I don't want you to leave on the way. For each other's sake, thank you."

Isaac bows his head with a serious face sometime.

Everyone had to admit it.

Because there's nothing I want to break my friendship with, and I know it's a stupid act, such as deciding to do this unilaterally before I listen to you.

Awkward silence persists until Norman returns.

"Thank you for waiting."

Norman brought the mat, carrying two hemispherical things on top of the basin and one spherical.

Place that in front of Isaac for each basin.

"Let me start by explaining what I wanted Sieghardt to make. This is what I named a grenade. Write pomegranate bullets you throw with your hands. Grenades. It holds a small iron sphere inside a pottery vessel and sprays it around with powder packed inside."

Isaac passes a hemispherical one that is easier to understand inside.

If it's hemispherical, you can see at a glance what the inside is made of.

It's not particularly difficult.

It's a simple piece of launching fireworks that I've seen on TV, with only two layers of iron balls and gunpowder.

If it was just about splashing iron balls around, this should have been enough.

The "Tetsuga" on which the idea was based was made in the days of the former Ko.

Isaac had the certainty that he could make it if he asked Dwarf.

"I tried putting sand in it and it weighed quite a bit. It would be a use of throwing it away with a sling rather than throwing it by hand because it is heavy on humans. Allow stone throwers to throw grenades instead of stones, collectively wounding enemy soldiers. That's what this is all about."

"You're telling me to build a weapon that makes mass killing possible? Even though we might be able to point it at ourselves?

Dwarf, who was accompanying Sieghardt, said with an uncovered look.

When people say they use it, it doesn't necessarily mean it can't be directed at them.

His vigilance was natural.

This question was well anticipated, so Isaac had a proper response.

"No, you don't. The first is in that it would be a weapon of mass murder, which I considered as a weapon that would not kill. Thanks to all the elves."

Isaac sees Mathias and the others.

"We don't always get the help of elves. But if we can get help, this can be a weapon that doesn't have to kill people. Mr. Mathias and Mr. Claude have accompanied us to the war against the Kingdom of Rockwell. You've also helped me with my therapeutic activities, so I'm sure you can understand. Even what I think is' this degree of wound 'for an elf, it's just not easy for humans to treat. With a few wounds, you won't be able to fight. Matt."

"Ha."

No one knows more about wounds on the battlefield than Matt.

Isaac entrusted him with the continuation of the explanation.

The mat removes about a centimeter of iron sphere from the sample.

"Injuries on the battlefield are something that makes you feel bigger than usual. So much so that some of the militias that have just been collected cry, even with a scuffle wound, to lower their will around them. Even the average soldier will lose his temper if he gets an arrow wound."

"They can't stop with an arrow wound."

Dwarf makes tea, but Matt answers flatly.

"That's because you Dwarves. Humans are weak. I understand that, so I lose my temper even with some scratches. Not only that, but the wounded will be luggage on the battlefield. You must attach someone who has not been injured by allowances or nursing care. Whoever has an arrow wound to his belly and a wound to his gut, it does not help him first. Sometimes my buddies stab me in the todome. It's dangerous for humans to get hurt so much."

As Matt finishes talking about the danger of injury, Isaac continues.

"So it's time for a grenade. Throw a grenade into an enemy unit queuing up. The explosion will only splash the iron sphere, causing numerous injuries. Of course, if the hit is bad, some may die. But it should be less than fighting normally. Per lot of iron balls, there will also be those whose lives are in danger due to bleeding. Treat and help there with elf magic. We have rescue teams to help the wounded, both on the enemy's side, so we can have a war where we don't have to kill them, even if we can hurt them."

This is a convenience for using grenades.

I still don't have the gunpowder on hand, so I couldn't even use a death row inmate to try the scope of the assault, etc.

If you don't actually use it, you don't know the ratio of casualties to deaths, etc., so it's all speculation.

All Isaac knew about the grenade was that it wasn't a weapon that would kill with a big bang, like in the movies, but a weapon that would kill with fragments.

He was explaining to them under the hopeful observation that "fragments would not die instantly unless the area was bad".

"Of course, this is a weapon that presupposes that everyone in the elves will help save lives. Some of them may hate it. However, life-saving is also good for all of you elves. Because, as we talked about before, the act of 'treating any enemy ally' is what makes countries other than the Reid kingdom understand the importance of elves. Since the Church is not involved in the battlefield in any way, its value is without those in line. No country should ever want to hurt an elf. For the future of the elves, it would be helpful if you could move on and help us."

"You mean we can only unilaterally hurt the enemy because we treat the wounded anyway?

……

Mathias questions sharply Isaac, who explains his desperate need for help.

Stuck in a response for a moment, but Isaac hasn't shut up either.

"We don't get our hands on the elves. Because I know you'll focus on treatment. So, what about the enemy? I actually treated the soldiers and sent them back, so the Kingdom of Rockwell should have figured it out. But other countries will only think to the extent that 'the elves are cooperating with the Kingdom of Lead'. If we lose on the battlefield, it could be dangerous for all the elves. Until elves are neutral and therapeutically focused, we have a duty to keep our elves safe. You can't lose."

"Hmm."

Mathias looks at the other elves.

The elves whisper and nod once.

"It's better than getting involved in a losing battle and being fought creating an unavoidable situation. That's the point."

Answered by an older elf who is not Mathias.

To the words, Isaac was thrilled.

Because I thought about it a little while I was on my way to reinforce the kingdom of Fatil.

"I ask you to fight with grandeur if you're going to go to war in such a despicable way."

Isaac answered with a strained chest, not even saying what he was actually thinking.

The elves seemed satisfied with the answer.

"Regardless of whether we cooperate in the war or not, we will be actively cooperating when it comes to saving lives. If we can establish a Church-like position by saving people's lives, it's not bad for us."

"Thank you"

The grenade was disturbed, but the threat was not well understood.

Maybe because of the thought that magic is stronger.

The elves showed a certain understanding.

I can no longer take the method of involving elves in battle on the battlefield, but that leaves me no choice.

Isaac switches his head and returns to explaining to Dwarf.

"A weapon to wound a human soldier. That's not a lie. You can adjust it to a degree of power that won't work on Dwarf's armor. Turn up the iron sphere, and more gunpowder will work on Dwarf's armor as well. So I want you to make something that doesn't pierce Dwarf's armor and that adjusts to the degree of power of piercing only human armor to sell it. I'm also prepared to give you a generic soldier's armor free of charge for testing."

Go to Sieghardt and emphasize that it is for human use only and ask him to make a grenade.

I don't know how effective it would be if I didn't actually use it, but the mental stability is very different from not having this.

Besides, the impact of "the general soldier used something magical" should be immense.

It should help break the morale of the Royal Army once and for all.

I almost wanted a gunpowder weapon.

But there was someone waiting for Isaac.

"Isaac...... You wouldn't have to have a weapon like that. I could have won the last war, so I wish I had you."

- It's Randolph.

He saw the reaction around him and thought the presence of grenades would not have a good effect.

For that reason, I try to convince Isaac not to force him to.

But Isaac never accepted that opinion.

After all, it was something that couldn't have been accepted.

"Father... Have you forgotten that half the soldiers were killed or injured in the battle of Sonicroft?

"I remember that..."

"Besides, even though the enemy was an overwhelming advantage that the commander was dead and confused and pinched from front to back. The weakness of the soldiers must be compensated with arms. Of course, when you return to Wellrod this year, you will gather the nobles under your umbrella for an exercise. If the soldiers were strong, I wouldn't have thought about new weapons like this."

"Right..."

It was just a huge damage in an overwhelmingly advantageous situation, although it could be said of the damage that came out of the fight.

Moreover, it was Randolph himself who was in command.

To Isaac's words, Randolph couldn't say it back.

"I see. I want materials to reinforce it because the army is weak. Dwarves are the only ones with gunpowder. So I'll also leave the manufacture of new weapons to you.... not afraid of technology spills means we've already figured out a way to counter grenades."

Sieghardt speaks.

He was trying to read Isaac's thoughts at all.

- Teach you how to make a weapon that injures a large number of people at once.

That's not just used by humans.

Dwarves can also be used.

You can't be thinking of a weapon that Isaac thinks is effective as "When it goes to war, Dwarves don't use it".

After figuring out how to deal with it, he thought he would be holding up the story.

But Isaac doesn't think about what to do with a grenade.

"In the meantime, I want to be ready to fight the Royal Army in the army of the Marquis of Wellrod".

Make an extra grin so you don't see through your heart.

"Commissioning the manufacture of weapons also means increasing reliance on Neuizen. At least there's less chance of waging a war here. Strengthen economic and defensive connections with Dwarves. Elves strengthen the connection between health care and life. It is not a vague" Let's Live Friendly Together "thing, but I believe it is a long lasting step towards friendship to prepare a reason that is easy for everyone to understand. That's why I need your help."

"If you have to, will you also be a weapon to get rid of humans? The development itself will not be complained about...... They're going to tell you how much to sell, and so on, you should put restrictions on it."

Sieghardt gives a troubled look.

He himself, even with his riding temper, can think of the opposite of his surroundings.

Maybe he's wondering how to convince me.

"Still fine. Dedicated slings and requests to be able to adjust the time to explode with a fuse line are written in the blueprint. I want you to be careful with accidents and get to the practical level as soon as you can."

"Okay. It's easy to make, so I think you can do it in a few months. Well, it won't take a year."

Sieghardt laughs niggly.

"That's good"

Isaac also gave it back with a bad grin.

Sieghardt knows Isaac's ambitions.

It's not that far.

I was trying to make the most of it as an accomplice.

And above all, Isaac's strong interest in seeing what he could do was driving him.
