From his previous life's experience, Isaac kept his summer homework done early.

I could afford that because of Tiffany's case.

I wasn't in the mood to go hang out with friends in my free time, so I did it while I was at home.

Thanks to this, I am able to enjoy the rest of my summer vacation.

So Isaac was thinking of inviting his friends to visit, but an unexpected opponent contacted him.

- It's a call from the piste.

The reason for the call is "you belong to the science department, so come out to the club during the summer vacation. Come rather than. I want to show you something, so please," he said.

Isaac is also a little concerned because he wants to show me something.

Though admitted to being a ghost member, I felt bad to ignore it altogether.

It is easier to play with school affairs.

Isaac decided to respond to the call.

----------

It was not the school that was called in, but the Wangdu branch of the Grey Chamber of Commerce.

While the workshops and warehouses lined up, Isaac was even guided to the meeting place by those working at the Chamber of Commerce with his escort.

The branch of the Gray Chamber of Commerce is the meeting point due to the convenience of the piste.

Pisto contacted the Gray Chamber of Commerce as soon as he found out that Isaac could support him.

To advance research that we have never been able to do, to borrow financial assistance and the arms of artisans.

Anyway, for a large organization, something as cheap as an individual's laboratory.

Build a cabin in the corner of the compartment where the workshop is located and make and give the requested parts.

This much is cheap considering what Isaac is making me earn.

The Grey Chamber of Commerce cooperated fully with the piste.

Thanks to this, Pisto had a more comfortable time in his life to enter into research than ever before.

I've been caged in the lab all summer.

For this reason, meals and the like are also taken care of by the Gray Chamber of Commerce.

Now it was so much so that the craftsmen working in the workshop thought, "You stopped being a teacher and started working at our house.

Isaac was looking forward to the results of the study, as he had so much input into it.

He may be making me something I can't make myself.

When I thought so, I was feeling excited.

It could be good news for a long time since one of Tiffany's.

I was honestly glad to feel bright.

Many objects were scattered near Pisto's lab.

Metal parts, wood fragments, slices of cloth, etc. are arranged in front of the inlet - no, they're thrown away.

Because of this, it displayed a look like a garbage dump.

(It's been less than three weeks since I've been on summer vacation, how dare you get this dirty...)

Relatively, it was an incredible sight for Isaac to organize himself.

The maids have been cleaning around me since I was reborn, so it looks even dirtier.

As Isaac was frightened, Raymond appeared from inside the lab.

"I've been waiting. Teachers are really amazing! I really made something like a steam engine!

"Eh, I made it!

Isaac was also surprised by this.

Because I never thought I'd make it in such a short period of time.

"Where? Where is it?

"Right there."

Raymond points to the site next to the lab.

Isaac turns his gaze to you.

There were two large objects covered with large sheets.

"I thought it was a material storage area, but this was the research."

"That's right! I just helped assemble a little too. I'll get you a teacher now."

As Raymond enters the lab, Isaac turns to the captain of the escort.

"It could be a boring story for a while, so you can all rest."

Isaac cares for them and gives them instructions to rest.

But we all got together and shook our heads sideways.

"Dear Isaac. You must have been fatally injured on the battlefield by that alarm. We will never leave!

The escort captain was served by Irvin.

He is a knight who once taught Isaac swords and horseback riding.

He was part of the Knights of the House of the Duke of Enfield on that edge.

In this way, when Isaac goes out, he rents knights and soldiers from the Marquis of Wellrod to act as the captain who brings them together.

I started using him because Matt and Tommy's names were oversold.

Using the mats as escorts to walk inside the safe king's capital is like breaking a chicken with a cow knife.

As one who stands above men, not only some of the good, but also new ones must be used.

"Okay. It won't be very funny to watch, but you can all stay here."

Isaac was overheard by Irvin.

It's true that I've been in pain, and it's necessary to let them do their job.

But it is also true that I think it would be boring to look at it.

Even when it comes to steam engines, they are preliminary at dawn.

I can't expect much.

It was Isaac's kindness to let him rest as long as he saw something boring.

But if anything happens to them, they'll be held accountable.

If you ever get injured in King's Capital, which is supposed to be safe, pursuit will not be a battlefield ratio.

I realize I should have let them work for me, not just for myself, but for them as well, without rest.

At a time like this, Isaac first thinks "let it rest" because he was struggling in his previous life.

"Isaac! Well done for coming!

"Doctor, Isaac is just out there."

Raymond came out of the lab with a pist and clan.

The only thing you can call "Isaac" is inside the Royal College.

Clan cautions the pisst that he has to be called "Lord Enfield" outside.

"Yeah, it's still snuggly. Before science develops, that's a minor problem."

The pissts are just as muddled by Irvin and the others.

Because it is the lowest act to belittle the position of the Duke.

I try to be cautious, but I'm not sure how far I can go to say it in the position of escort.

If Norman was here, he would have been careful.

The only place like this is the new ministerial corps, and the area where you can step in remains obscure.

I almost had to take the time to work it out.

Now that there was no sign of Isaac protesting, Irvin decided to sit still.

"It's a waste of time talking like this. Let's have a look at how great things have been."

Quickly head to the place where the pist was placed next to the laboratory.

Follow the clan as well and help the pist try to exclude the seat.

"Ooh!

I thought it would be boring anyway, but a big machine about a meter high and wide and two meters long.

Isaac had remembered the excitement in front of a full-scale machine for the first time in sixteen years.

Multiple pipes extend and a large chimney is attached to the top.

At the bottom was installed something like a large firewood stove, with charcoal inside.

Unlike steam locomotives and other things I've seen in my previous life, I get the impression that the mechanical part is just bumpy and muscular.

But I'm glad about that.

Because I felt as if I had entered the world of steampunk.

"How much horsepower is this...... Do you use your powers?

"Not yet, I can't exert a lot of power. This is for checking the operation. Unfortunately. But if you look at it, you'll see."

While we were talking like this, Raymond was bringing artisans from a nearby workshop.

Craftsmen have something like a spark.

"Let's put it into practice, then. Come on, light me up."

Seeing as Isaac was interested, the pisst was in a good mood.

Because I felt that realizing the prototype of the steam engine had finally brought me one step closer to Isaac.

When the artisans lit the charcoal, it was looking good for a while until the water warmed up.

Not only Isaac, but the knights and soldiers accompanying him watched breathlessly.

Eventually, when the steam starts to erupt from the chimney, you start to hear something called karakara spinning.

"Look, look at this. The power of the steam would be turning the wings, right? This is a smaller windmill blade. Now I can send the wind without having to use our wax. The first step."

"That's the teacher!

Clan applauds, but Isaac remained distracted.

The pisst was receiving the reaction "I'm not very impressed with it," he said.

Because those who followed Isaac as his escort have a stunned look.

I thought Isaac must be the same.

- But actually, no.

Isaac was stunned by the fact that it only served as a small fan for a big device.

(No, you can't. You shouldn't show the color of disappointment. I have to praise you......)

Soon Isaac recovered.

Expecting enough to move a carriage from the beginning is something called cruelty.

If you think it's an experiment to see how it works first, it would be a great category.

"Well, the first step is success, right? Congratulations."

"Thanks"

As Isaac offered his right hand, the pist gripped back with a gutter and both hands.

Irvin and the others also feel "I don't know, but I saw something amazing happen" and applaud the pistol.

"I don't know what's great about it, but I wonder how much Lord Enfield praises it. It was worth 50 million leads."

"What, 50 million?

- Fifty million leads to the fan.

Isaac was surprised by the whining of the merchant members who guided him so far.

"It costs money to develop science."

"Given how it works, I'm glad I just put a place on the firewood stove to boil water..."

"It costs money to develop science."

To Isaac's clinging, Pisto repeated the same words with a smile.

Seeing that smile, Isaac realized his failure.

(Oh, this guy can't do anything but science! If you can spend as much money as you want, don't hesitate to spend it!

"… I can't help but spend money on research and development, but change the way you invest in things that just look at the movement and things that are geared towards practical use."

"Of course I know. This is a prototype of fate!

Pisto's eyes are serious themselves.

I didn't look like I was lying because my eyes weren't swimming or anything.

He takes off the seat that was hung on another big thing.

At first glance, I knew that you were different from what I had just seen.

The pipe in the chimney section bent squarely and the area close to the ground was passing through the tank.

"Cons of steam engines. It requires a lot of water. I thought I would, so I took advantage of the experience of making distillers."

"What do you mean?

"Cool the steam and turn it into water again. Doing so reduced the amount of water consumed and allowed it to run for a long time."

The pist tenses his chest and explains how the new steam engine works.

That was convincing to Isaac.

(The steam locomotive was loaded with coal and water for one vehicle. It's amazing how you can even think of saving water!

Expecting that brains in monetary terms doesn't seem too late when technology matures.

"Well, let's get this thing moving."

Following the words of the piste, the craftsman also sets fire to the new steam engine.

Charcoal ignites and gradually warms up.

But over time, Isaac's anxiety also increases.

(Is that it? That's crazy. Something's wrong...)

Isaac sighs at the mechanical part.

There must be something missing about feeling anxious.

I'm afraid I don't know exactly why.

"Ah, put out the fire! Then, immediately everyone else evacuates! Run!"

"What, are you evacuating?

Irvin listens back, but at that time Isaac was seriously running away.

Hurry up and chase them too.

About fifty meters away, Isaac stopped.

"Raymond and the others get away. That machine will explode!

What Isaac noticed was the thickness of the chimney and the size of the tank.

Experience with distiller creation has somewhat shown that steam will not cool in time.

Keep it running, and sooner or later the pipe will burst at a loss to vapor pressure.

It would be catastrophic if that happened.

That much, Isaac, who is not familiar with science, also found out.

But there is no rush color in the piste.

No, he wasn't the only one.

Raymond and Clan have not escaped either.

Rather, it was enough to give me an extra grin.

"I'm fine. Isaac won't be worried about you. You should come back."

The pist is calling Isaac back.

The Raymonds aren't in a hurry either, so I guess they're safe.

Still anxious, let the escorts set up a shield and get close to Jirijiri.

"You don't have to be so vigilant. Even I'm not stupid. Once the pipe is broken, think about what to do."

"I knew it was broken..."

Hearing unsettling words, Isaac hid behind the escort.

"I do feel uneasy, but I'm really fine this time. Look, look at the outing up there. That's what the teacher thinks of as a safety valve."

"Safety valve?"

Hearing the words he remembers hearing, Isaac faces from behind the escort.

"Exactly. Steam is larger in volume than water. If the steam escape is not prepared and the cooling is not done in time, one day the pipe will burst without holding off the inner force. Then you can let the steam escape before you reach its limits."

Pisto laughs niggly.

"It was the spring that came in handy here. The hardness of the spring can be adjusted to allow the steam to escape as much as necessary. Thanks to this, technology has been achieved to reduce water consumption! Take that as a valve for safety. I named it the safety valve!

Behind the pistol, which spoke fervently about the safety valve, I heard the safety valve open and the steam coming out of the psuew.

"But now I can only draw enough strength to turn my wings. Okay, here's the problem. In what direction should steam engines develop from now on? Can anyone answer that?

Suddenly, the pist said something like a teacher.

(Speaking of which, are you a teacher...)

He turned his gaze to the students and nodded to answer.

But Raymond and Clan can't answer instantly.

It's because I couldn't handle the new technology right away.

Isaac answers instead.

"High performance first. In doing so, you'll be getting bigger. Although it will be high performance and large, one day performance will hit the head. Then, miniaturize while maintaining performance next. It will have to be miniaturized and developed sequentially while enhancing performance."

"Exactly! That's Isaac. I didn't know you understood that much about technology!

Pisto put his arms together and nodded big to his satisfaction, yeah.

Isaac was given the technical answer because it was in a book on engines that he had read in his previous life.

The engine grew larger in search of performance, and where it had developed to some extent, it seemed to aim to become smaller and more high-performance.

Thanks to reading the book in his previous life, Isaac was able to answer it perfectly.

"After all, Isaac has a technology field for him. Let's bring innovation to the world together!

"No, I have something to do, so I'll leave it to the teacher."

Isaac clearly said no.

Because I thought it would be better for me to pass on my knowledge of wanderings to the piste to make it happen rather than for me to be in full swing into technological development.

Pistons are making trial and error attempts to achieve safety valves and water reuse using matching techniques.

This is something Isaac probably didn't realize he was trying to do himself.

I would have been satisfied making only minimal features.

A large steam engine for the first waste may also have been needed as a basement to create the second.

Among the things I thought were useless, there was something I needed.

This was the difference between researchers and those who did not.

Pisto ignores other things for research, but Isaac thinks "money is wasted" and other extras.

Strong are those who can move forward without hesitation.

To be honest, Isaac had to admit the vitality that seemed "I guess this kind of person will lead the way in the times" although he was pulling to the piste.

"That's a shame...... So, could you introduce me to the Dwarf craftsman? That way the steam engine will develop more. Today's technology is anxious about the durability of every single part, and I can't design it thoughtfully. At least if you get just Dwarf iron..."

"I wonder if the iron, close to that made by Dwarf, would be available if a new melting furnace in the Marquis of Wallick territory were to become operational. As for the Dwarf craftsmen...... I don't know what's going to happen, but I'm going to ask my friends and ask them if they can do something about it."

"Whoa, yes, please! Once you get Dwarf's help, there's something else you need to make!

"Please don't let Dwarf hate you so much."

Isaac didn't forget to stab the nail.

Not to mention steam engines.

A technology that will be a must in the future, but now friendship with Dwarves is more important.

If Dwarf hates me by pretending to be impotent, it is the end of the line.

I just wanted you to stay strong there.

"Raymond, Senior Clan. You might get Dwarf's help someday. I asked for the teacher."

"Sure, I'll take a good look."

"Leave it to me."

The two of them have not yet become explorers of science like pists.

It would stop the pisst with a common sense decision.

Isaac turns his face to the Chamber of Commerce.

"Please provide adequate support for your teacher's research. Chairman Ralph has something to say, and if you're going to spend too much money, charge me."

"Yes, I did!

The merchant member replied that way but felt like Chairman Ralph was going to piss me off "Don't charge Lord Enfield".

It would be more profitable to sell a favor than some money.

It has always been so.

Thanks to the sincerity shown in his bid for iron ore, he is now able to trade with Dwarves as a matter of priority.

If you want to clean up with money, you should take care of it at the branch office.

He thought it would be a consultation with the branch manager later.

"Come on, Isaac, you're designing with me! Science is still evolving! How about you guys at the escort? Even those who are not interested may unexpectedly come up with insulting opinions. You're welcome to join us!

A pist tries to get Isaac to the lab.

That's not all.

I was thinking of getting involved with even the knights of the escort.

If Isaac gets into the lab, nature and they have to get in, too.

Like Raymond, interest in science should come out once you know it.

Today, I didn't just want to show you the steam engine that called Isaac in this way.

If you just want to show it, you can show it at school after the second semester starts.

- I called in today to increase the number of people who seemed to be of renewed interest.

But no malice there.

It was poorer quality because it was only good intentions (...) and I'm trying to teach you the beauty of science.
