Time imperceptibly, into the summer.

The summer of the eleventh year of Jian'an was not good news for Zhang Xi.

It was a bit hot, especially for Zhang Xi.

Really, Zhang Xi really can't understand the ancients, why do they have to dress neatly in the summer..... Isn't it good to cool off the whole vest and pants in your own yard?!

But Xiao Qibao desperately opposed this, saying that this was a loss of etiquette and a sign of lack of cultivation.

Zhang Xi has always had no way to take the little Qibao, and now there are two more girls in this courtyard...... Zhang Xi could only put away the vest pants that he had secretly cut, put on a slightly cooler silk lining according to Xiao Qibao's requirements, and then put on a burlap jacket outside.

Of course, aristocratic families can wear all-silk clothes, but right..... In these years, the output of silk is not too high, and there are not many people who can wear silk at all, most of them are like Zhang Xi, and having a silk lining is already very remarkable.

For example, Guan Ping.

The eldest son of the dignified Hanshouting Hou family, that is, like Zhang Xi, wears a silk lining, and the outer coat is still linen...... Listening to Guan Ping's gossip, Guan Yu didn't even wear a silk lining, and all the silk he saved was left for Mrs. Guan and the eldest lady of the Guan family to make clothes.

I have to say..... Guan Yu's figure, more than 1.9 meters tall, and a silk lining is indeed quite expensive.

Well, that's.

Guan Ping came to Zhang Xi, and he really didn't come to chat.

Half a year ago, Zhang Xi went to Guan Mansion to inquire about Guan Yu's oil extraction, and Guan Ping came to reply to Zhang Xi today.

This is the ...... Well, if Guan Ping didn't mention it, Zhang Xi himself would have forgotten about it.

At the beginning, Guan Yu promised that he would tell Guan Ping the oil extraction method he knew, and let Guan Ping convey it..... But listening to Guan Ping, Guan Yu felt that it was inappropriate to do this, after all, oil extraction was a big matter, and it would be better to get a more detailed way.

So Guan Yu repaired a book, asked someone to take it back to his hometown in Hedong, asked his friends to help, and found a person who knew how to squeeze oil for Zhang Xi.

It took half a year to come and go.

That is, now Guan Yu is the Hou Ye, or the kind of Hou Ye certified by the imperial court, otherwise Guan Yu would not have the face to let the family that controls the oil extraction technology send him a technical talent over.

Guan Ping came to visit today, just to ask Zhang Xi if he could prepare for this bean squeeze oil.

What can Zhang Xi say, you have found specific skilled workers, so let's do it.

First of all, you have to get the tools out.

This is not difficult, there are old oil presses, and tools and such things are quickly made.

The next step is to ask the old oil mill to try to squeeze the soybeans the same way they squeeze flax seeds.

The way to squeeze flax oil is basically to stir-fry first, then dry and then grind on the stone, steam and wrap into cakes, and then stack these cakes neatly in the oil trench of the main press, squeeze them tightly with wooden wedges, and then open the oil after loading, and the oil that is squeezed out will flow down the groove to the oil drum on the side.

It turned out to be very simple, that is, by squeezing and impacting, the oil of flax seeds was squeezed out...... I guess it's pretty much the same if it's changed to beans.

Then I gave it a try.

Well, it turned out to be a success, and the oil was squeezed out.

It's just that, compared with the oil yield of flax seeds, the oil yield of tofu is only about one-fifth of that of flax seeds.

The oil presser is tired and half dead, and he can usually produce a barrel of oil, but this time he only squeezed out a fifth of the barrel...... The oil press's face was flushed with shame.

"I think the old man is not skilled enough ......to squeeze out much oil," said the oil presser, blushing.

This is a sincere person...... Although this oil yield does have some problems.

Guan Ping also looked at Zhang Xi puzzled, wanting to get an explanation from him.

Zhang Xi said...... I don't know wow, I don't know how to squeeze oil.

"Although this bean can also produce oil, but if it is only ......" Guan Ping thought for a long time, and didn't know what to say, so he could only sigh and say, "If so, it is better than nothing!" ”

Guan Ping was somewhat disappointed.

When I heard that bean can squeeze oil, he and Guan Yu thought that it could squeeze a lot of oil, so they paid special attention to it.

But now it seems..... If there is only this oil yield, it is better to have a variety of flax seeds in the future.

But Zhang Xi doesn't like to hear this.

Anything is better than nothing.

Do you know that soybean oil is much more widely used than sesame oil in later generations, and the planting range of soybeans is much more extensive than sesame seeds, okay!

In later generations, soybean oil was basically used for stir-frying, while sesame oil was only used for seasoning later...... Which is more important, you know not?!

But because of this, Zhang Xi always felt that this was wrong, and there must be something wrong.

The oil yield of soybeans is not as good as that of sesame seeds, Zhang Xi still knows this...... But at only one in five, that seems too low.

"I wonder what went wrong...... It shouldn't be! Zhang Xi thought for a moment, turned his head to the oil presser and said, "Uncle, please advise...... This flax seed is oily, what is the point of it?! ”

The old man first glanced up at Guan Ping, and when he saw Guan Ping nodding, he didn't dare to say to Zhang Xi, "Is this flax seed, grinding, steaming, and squeezing...... will affect the oil, but the old man doesn't know if this bean is the same. ”

Well...... I don't understand what you're talking about.

"That being the case, please worry more about the old man and try a few more times." Zhang Xi saluted at the oil extraction work, and the old oil extractor knelt down on the spot.

In these years, the officials are not happy to salute the people, and Guan Ping feels strange when he looks at it.

What can Zhang Xi do, who made him really not know how to squeeze oil, and although this old man only squeezed a little bit of oil, he knows how to do it.

When it comes to technical experts, you can't afford to slack off.

After that, what Zhang Xi can do is to provide enough support to this old man, whether it is "R&D expenses" or "raw materials", he has to give enough.

Don't underestimate the working people in these years, how many great inventions and creations come from them, not the so-called Confucians.

The money has to be invested, and the craftsmanship has to be bold for people to try...... If the process can be improved to the point that the oil output is one-third of that of sesame oil, then the investment will be completed.

After all, the planting range and yield of bean soybean are placed there, as long as there is one-third of the oil yield of sesame seeds, the oil extraction of soybean is not a loss.

If you can't do it...... It's also a supplement to the source of oil.

In these years, is there still too much oil?!

Then don't eat meat in the future, eat vegetarian life.

This matter will be put on hold for the time being, anyway, this oil refining workshop is also under the control of the Guan government, so there is no need to worry about leaking secrets or anything.

After that, it was rare to meet Guan Ping, and it happened to be time to be on duty, Zhang Xi and Guan Ping called Kou Feng together, and the three of them went to the only wine shop in Xinye County together and ate together.

In this year, the liquor shop still can't sell alcohol, because Liu Yuanjun won't let it, but he has food to eat.

"It's getting hotter and hotter this day, and it's not allowed to drink alcohol in the army, and there is no wine to drink even in the restaurant, but it's going to kill people with thirst!"

Before he could take a few bites, Kou Feng's complaint came.

Just listen to that.

Anyway, Zhang Xi can't understand why drinking alcohol can quench his thirst, but drinking water cannot.

Theoretically, isn't it true that drinking alcohol will make you thirstier the more you drink?!

Even if the alcohol content of the wine is low in these years, it is still wine, so how can it quench your thirst?

In essence, Zhang Xi thought that Kou Feng was just hungry and wanted to drink.

Guan Ping was also laughing over and over again, but he didn't speak.

Drinking is a common hobby of people with a little bit of conditions in this era, and Guan Ping also likes to drink.

But it's not good to say this in public, after all, it's the uncle's ban on alcohol, Kou Feng complains about nothing, if he, who is a nephew, complains...... If Guan Yu knew, he would probably have to specialize in the method.

And Kou Feng saw that neither of the two of them paid attention to him, but he was not satisfied.

Especially Zhang Xi, he is a brother anyway..... The little brother wants to drink, you can't think of a way?!

"Brother, why don't you speak?!" Kou Feng turned his head and said to Zhang Xi, "My brother is also a high-ranking person now, so he must have a good wine hidden in the house..... Why don't you invite your brothers to have a drink?! ”

"This is the!" Zhang Xi shook his head speechlessly and said, "Haven't drunk yet?!" It's not like you don't know, I've never been good at drinking, and when will I hide it?! ”

"Eh, my brother is not telling the truth!" Kou Feng was also unrelenting, and said, "Although the elder brother is not good at drinking, the younger brother knows that now the elder brother is even trusted by the three generals, and the three generals have no wine in the tent, and they have never shared a jar with the elder brother?!" ”

"Huh?!" Zhang Xi's eyes narrowed slightly.

Co-authored this black guy and secretly hid wine and drank again?!

Thinking of this, Zhang Xi asked quietly, "Although the third general also said this, he also said that I should take it myself...... But I have a good face, and I don't know where the three generals put the wine, so I never took it! ”

"Eh, brother, why bother with this face!" As soon as he heard this, Kou Feng became anxious, and Guan Ping began to cover his face.

"The younger brother knows where the three generals hide the wine, hurry, hurry, the younger brother will take the elder brother to get it quickly, and he will rest when he gets drunk tonight!"

"So...... That's good! ”

After speaking, Zhang Xi set off with Kou Feng and went to Zhang Fei's military camp.

And Guan Ping..... Hurry up and keep up, if he is found out in a while, he will be able to stop him.

is not to stop Zhang Xi, but to stop his third uncle.

If the third uncle knew that Kou Feng had exposed his little secret, he wouldn't have to whip him fiercely?!
