To be fair, while Yinla's research on bellows wasn't exactly expert, it was downright clueless... even though Yinla was a university graduate in the Department of Ancient Studies.

He also graduated from Star Trek Rapid Penguin Academy with excellent grades before the end of the machine world... But he was still a college student, even though he was a college student with outstanding academic performance.

Unlike the ancient professor, he didn't have an overly clear understanding of events from four hundred years ago.

So it's already quite remarkable that he's been able to replicate so many inventions, innovations, and reforms that were significant in the world... But when it comes to the more specialized parts, he gets a bit stuck.

For example, with bellows, although he knew in his heart that a conventional lever-type bellows should not have this ordinary structure, he was still quite stumped when it came to thinking about how to improve it.

Pull the bellows, and air is drawn into the bellows from the air inlet at one end. Then push the bellows out by hand, and the air that was drawn in is expelled from the exhaust port at the other end... This is the classic bellows.

That's the principle, and it's really hard for Yinla to forget the professional knowledge that will be tested, but... the bellows in front of her should be similar, at least in appearance.

However, the air delivery felt quite poor...

"It's up to you now!"

As Yinla spoke, looking at the goblins in front of him who were already dressed in coarse cloth clothes and had small saws and hammers hanging on their bodies, he patted them on the shoulder and said, "The improvement of the bellows depends on you."

"Yes, Lady Yinla!"

"Know!"

"Mission accomplished!"

"..."

Watching the little goblins and a few lesser demons immediately start enthusiastically banging on the bellows, Wolf, who was observing, smiled helplessly and said, "Ira, actually, I don't think there's anything that needs to be improved with the bellows we're using now..."

As she spoke, Wolfe gestured casually, explaining to the little goblins, Satanieh, and Illa, "Pull the suction, push the blower... It's a very simple structure, isn't it?"

Yes, it is indeed very simple, but to say that there is absolutely no way to improve it is definitely not true... In Yinla's memory, there must have been some iconic transformation that brought the ancient refining industry to its peak.

Although the electrical age came immediately afterward.

"..."

If all else fails, the only options are to use an automated wand for heating or to use an automated wand for blowing air... but this would require a significant amount of mana reserves from the craftsman.

The werewolves who showed great talent in the glassmaking industry could only continue to study magic armor making with great difficulty... If they were to be classified, they would actually belong to the combat profession, and in the area of ​​mana, they really couldn't compare to magic-type monsters.

If I had known the world would end and I could time travel, I would have read more basic professional books.

Yinla was somewhat helpless. In his plan, although glass was not a particularly crucial step, it was a good way to make money, just like white wine and bee flower snow moon... as well as the white sugar and soap that were also in the works.

To perfectly resolve the potential impact of the Empire, and even to counter it... sufficient funds are essential.

Gold coins are the medium of exchange, but this world has no paper or pen. So if the Empire's gold coins flow continuously into the Demon King's territory, then collapse will inevitably follow... or a war.

The latter is inevitable, but the Empire... would never dare to attack the Demon King's territory where Ira exists.

As for why...

...

Imagine this: on the battlefield, when the two armies are facing off, Yinla goes to the battlefield and sees... well, wow, everyone's a familiar face. Ulrichila is leading the team, followed by Shara, Gureira, and some other governors.

At this moment, Yinla shouts, "Come on! Follow me! Trust me! Has your brother Yinla ever lied to you?" What will happen then? Well... perhaps some people will still become Yinla's enemies, but most will definitely follow Yinla.

The troops, who were putting up a stubborn resistance, turned around thinking of asking Isabella for some help, but when they looked closely... well, why did Isabella also go with Isabella?

Soldier: Where is my empress?

Isabella: I don't know~

...

While Yinla wouldn't actually use emotional appeals to induce her former allies to betray her, on the battlefield, she would probably say something like, "Let me see if my students have grown; there's no need to hold back!"

But at least the empire will use force cautiously...

Therefore, whether we fight or not, it is absolutely necessary to make a lot of money through various means... Moreover, the current expenses are indeed not small.

Besides the expenses that existed before Yinla's arrival, such as food-related items like spices and fruits, utensils, and steel, Tops' research on the automatic staff requires a large amount of mithril... which is also a significant expense in gold coins.

However, I now buy a lot of fruit from Silver Moon Tree Garden, which is finally cheaper.

Thinking this, Yinla looked at the goblins who were having a heated discussion, nodded to Satan Ye, and said, "Then, let's leave this place to the goblins for now. Let's go find Mr. Lem... and ask him if he has any extra lard."

Soap... no, bar soap, it would definitely be sold to the duchy, where it could fetch an outrageously high price, given the duchy's notoriously extravagant lifestyle.
