Eventually, Otto found the fist commodity for the territory of the Swabian region - soap.

Yes, that's right, it's soap.

Soap is not difficult to make, the raw materials are easy to obtain, and the most important thing is that the manufacturing process Otto just remembers.

There is no difficulty in making the method, prepare some plant ash, filter it and heat it with water, put in animal fat, such as lard and butter, and finally add a little salt, and put it in a container to solidify.

Of course, this kind of simple thing is definitely not enough, just add some flavor to the soap and turn it into soap.

Anyway, although the raw materials of this thing are easy to find, the price is not very beautiful, and the consumer group can only lock in the aristocratic class. Since the aristocracy is locked, it is natural to make it more forceful, and those nobles will buy it.

It wasn't until after the outbreak of the Black Death that Europeans really began not to bathe, and before that, the aristocracy, who were deeply influenced by Roman culture, did not build their own elaborate bathhouses, but the aristocracy still loved to be clean.

Moreover, only the nobles were allowed to bathe every day. Boiling hot water also costs money and time, and the poor are naturally not eligible to enjoy it.

It's all a pit aristocracy, even if animal fat is a little difficult to get now, it shouldn't be a big deal.

Otto thought of another idea of a rich country and a strong army, but unfortunately due to geographical conditions, it cannot be used for the time being, and after taking Croatia and having the Adriatic Sea, it can be used.

Spirits, soap, this kind of rotten street stuff I still use, I really am a shame of a traverser, I knew that when I first read the novel, I would have learned a little more knowledge, I really hated less when the book was used, Otto thought to himself.

Otto personally found the craftsmen and showed them how to make soap, no, soap, and saw the finished product in less than a week.

One of the main delays is the process of making flavors and turning soap into soap.

Otto looked at the soap made by the craftsmen and was extremely satisfied, this thing, if added to a beautiful packaging, should be enough to pit the nobles' money.

Before the soap didn't sell well, Otto couldn't reduce taxes, no way, and Otto didn't want to, but there were so many people under his hands to raise, so he couldn't let Allgaux feed Swabia back.

In order to test the appeal of the soap, Otto found his wife and gave the soap to her.

"What is this?" Sophie blinked her big pretty eyes and sniffed with her nose after taking it.

"It smells so good."

"It's for bathing." Otto smiled slightly, the reason why he specially sent soap to Sophie was that Otto remembered that the other party's birthday seemed to have passed not long ago.

In other words, now that the other person is an adult, it's time to do something that an adult should do.

"For bathing?" Sophie looked at Otto suspiciously. "How do you use it?"

"How to use it, hehe, I'll teach you." Otto leaned into Sophie's ear with a wicked smile and whispered, wrapping his arms around the other's waist.

"The servants are still there." Sophie blushed instantly.

After a fierce battle, Otto looked at Sophie, who was lying asleep on his arm, and smiled, in the medieval situation, Sophie was so innocent, she had to thank the Sighard family for her family style.

Perhaps, future generations have never heard of this family, it is because this family is too pure love, which led to the extinction of the heir?

Now that the soap was out, marketing was needed, and Otto thought to the clergy of the church.

These people seemed to be richer than the nobles, so they returned to Aargau with the first batch of soaps they had made.

Originally, I planned to go to Linz, but when I saw the situation of Swabia's territory, I thought that the Linz area was not much better. Second, I heard that the West Slavs, now the Duchy of Moravia, were about to break out into war with the Duchy of Bavaria.

This kind of small-scale war between the two sides has to come almost every year and a half, and in order to avoid being affected, Otto still chooses to forget it and wait for the next opportunity.

At this time, almost two years have passed since Otto left the Allgau collar. You must know that although the war ended quickly, it also took more than half a year, plus the pull of the treaty signed by the two sides and the final territorial exchange, when Otto was named Earl of Navel, it was more than a year since the start of the war.

Later, Otto was delayed for a lot of time because of various relations with the nobles, and finally went to Swabian territory to inspect the area, so that Otto came back so late.

Fortunately, in the past two years, the territory has not been a big deal, and through the messenger, Otto can basically understand and control the situation of the territory, and everything in the Allgao Collar is stable and improving.

It's just that what Otto didn't expect was that just after returning to Eagle Castle, Baron Charlie reported two such exciting news to him.

"You mean, there's some closeness between Lady Kaylin and one of the squires in the Old Castle?" Otto pondered the wording, and he also thought it strange that his cheap dad was cuckolded.

"Yes, but I don't think it's a big deal, just tell the young master to let you know. Young Master, if you mind, I can have someone drive that guard away. Baron Charlie clearly didn't take it seriously, and nodded with a smile.

According to the rules, now that Otto has become the Earl of Nahuel, everyone under his command should call him Lord Earl. However, since Count Aargau was still alive and Otto was in charge of the Allgau Collar as regent and heir, the people below were still accustomed to calling him Young Master to show respect for Count Aargau and his closeness to Otto.

Otto didn't mind the use of these titles, not even that Lady Kaylin was looking for a lover.

Finding a lover, among the aristocracy, not only is there nothing bad about it, but it is something worth showing off. For example, in Aachen at that time, Otto heard a certain nobleman boast that he had two hundred and twenty-nine mistresses, most of whom were noble women, and the nobles present showed envious eyes and praised him one after another.

It's just that Otto can't help but think of the simple and kind Sophie again, and when he thinks of the identity of the other party, he still feels a little uncomfortable.

"Mind Madame Sophie, a little more restrained, I don't mind, but at least I don't want to hear any gossip. The Habsburgs and the Alakhor family did not want to be famous for their romance. ”

"Okay." Baron Charlie nodded.

"So, the proposal from the Count of Zurich? How do you think about it? ”

Baron Charley's proposal from the Count of Zurich was that the Count of Zurich wanted to exchange Zurich and Otto after hearing that Otto was willing to exchange Nahuel for it.

Otto really wants to get rid of the enclave of Nahuel, but if he exchanges with Zurich, he will take Neuchâtel, Bern and other places in a row.

He controlled almost half of the newly established Duchy of Alemania, so it would definitely be noticed by the Duke of Swabia and other nobles, which was not conducive to his desire to develop in a low-key manner in the past few years.

But if he didn't agree, it might be difficult for Nahuel to change to a territory like Zurich that Otto felt comfortable with.

Although he could take Zurich and then Tubern first, Otto was also afraid that behind this, which nobleman was testing his ambitions.

"Hmm," Otto said slowly after a moment's silence, unable to make up his mind for a moment.

"It is better to invite the Count of Zurich to be a guest at Eagle Castle for me, this kind of thing is better to meet in person."
