I do research in ancient times

When Ning Fei came out of the bathroom, Feng Kai was sitting in his outer hall reading military newspapers.

It was already evening at that time, the windows of the outer hall were not closed, and the night wind made him shiver.

Feng Kai stood up when he came out, put a robe on him naturally, and then took the cloth to help him wipe his hair.

"I heard that you used soybeans to extract oil today."

he asked with a smile.

Ning Fei was taken aback for a moment, then remembered that the oil extraction team was indeed all his troops, and nodded.

"Try to play, the effect is good."

"Have Lu guys reported it to you?"

Feng Kai shook his head.

"When I entered the city, I saw people walking towards the food hall, saying that it is your style to squeeze out new oil from beans."

"my style?"

Ning Fei raised his eyebrows, and the corners of his eyes were slightly provocative.

"What style do I have?"

"Using small to make big gains is a wolf with empty gloves."

Feng Kai loved his unruly expression, brushed the hair from his cheek, and kissed him by the way.

"From before to now, it has always been."

Ning Fei was tickled by his kiss, couldn't help pushing him, and smiled half-truthfully.

"If I'm a wolf with empty gloves, what are you? A wolf with a big tail in a jacket?"

"So what?"

The man exerted strength with both hands, lifted him up directly, and put him on the couch.

"The prairie wolf is ferocious and brave, and the hunter will have a headache when he sees it. The alpha wolf only finds one partner in his life. If one partner dies, the one who survives will stay in the wolf's den and die alone."

His hand slowly touched Ning Juzi's slightly thin back.

"Brother doesn't like it?"

Ning Fei couldn't help but blush when she heard him call this title.

I don't know what brother Muye thinks, since that day when they flirted with each other, he likes to call him that when they are alone, and even forces him to call him "brother" when they are passionate.

At first, Ning Shaozi felt ashamed, and suspected that Brother Muye had orthopedic tendencies.As a result, after he secretly observed during this period, he found that Brother Mu Ye always called his biological brother Feng Kang by his first name or preface, and Feng Kang would only call him "big brother" or "boss", calling him "big brother" or "boss". When I was "brother", I really didn't.

Well, I guess this is Mu Ye's interest.

"Brother likes... how about brother? Do you like it or not?"

The hands gradually climbed up, and through the thin fabric, the hot temperature penetrated into the skin, bringing a slightly itchy touch.

Ning Sawzi smiled and nodded, generously.

"Of course I like it."

"If I say I don't like it, my brother will punish me like yesterday, so I won't be fooled."

After finishing speaking, he leaned forward and kissed Feng Kai's lips directly.

He wanted to tease him and run away, but was killed by the other party. He held down his neck and attacked the city, and he didn't let go until he was out of breath.

"Little bastard."

Feng Kai scolded softly, and pressed the boy even tighter, causing him to chuckle.

"Hey hey hey."

Ning Zaozi's eyes were bright, and he reached out to point at brother Muye's waist, but was firmly held down the next moment.

Young Master Feng's eyes were burning with fire.

"Don't make trouble."

"No trouble."

Feeling that brother Mu Ye was a little excited, he couldn't help but want to move his body to avoid it.As a result, his anger was wiped out, and he was hugged and sat on the man's waist, and the other party moved as if warning.

Ning Saw raised his hands above his head, and blinked solemnly.

"Brother, I was wrong."

"Brother knows that brother is not in good health and cannot be stimulated, otherwise he will be sick and unable to get out of bed."

"My brother is reluctant to let my brother suffer."

One bite at a time, "Brother", shouting so that Mr. Feng was furious, and he taught the little bastard a lesson.

But still remember his frail body, asked hoarsely.

"What about your Mo Zong's technique? Isn't it good for strengthening your body?"

Ning Fei was taken aback for a moment, and then remembered that he had bumped into the physical examination before, but he didn't expect that he still remembered the reason for the random nonsense.

Ning Fei gave a dry laugh.

"How can it be so fast, and it's not a fairy spell, it will take some time to slowly improve."

Feng Kai didn't speak, but stared at him for a long time, then loosened his restraint, and put him back on the couch.

"You."

He sighed, got up and sorted out some messy clothes, pushed the door open and walked into the night.

Ning Fei lay in front of the window and looked at it for a while, knowing that he was looking for trouble with Twelve Lang, he laughed twice, put on his robe and walked to the study.

The evening entertainment is over, he is now going to work, and the influence points are still waving to him!

When Feng Kai came back, Ning Fei was racking his brains in the study.

His idea is very simple, which is to produce a large amount of vegetable oil in a short period of time, put it on the market quickly, and let the vegetable oil spread to the Central Plains as much as possible before the mission is completed.

To achieve this, the output must be guaranteed, and there must be sales channels.

This year, the harvest of soybeans in Jiuling Lake and the frontier army's field is good. If you want to make money, you can directly supply them to the frontier army, and you don't need to work hard to find buyers.

Ningfei's goal is not just to make money, but to maximize his influence.

In terms of the actual situation of the frontier army, the number of people may be a factor that can be considered, but the influence is too limited, which is not conducive to the improvement of points.

So, still have to go the business route.

Donghu Sanbu is a potential customer group, but unfortunately, before the spring equinox next year, it is unlikely that the Feng family will use troops against Bailukou, and the sea route will not be open to traffic for the time being.

There is only Ding'an City, south to the Central Plains trade route.

Merchants are not difficult to find. Aunt Mei has been running a shop in Ding'an City for some time, and has accumulated a lot of contacts. As long as the goods are good, naturally no one will come to her door.

So the problem is still in the output.

Thinking of this, Ning Sawzi became a little annoyed and bit the barrel of his pen.

This is his custom-made graphite pencil. It is made by hollowing out wooden rods and filled by skilled carpenters. It is not much different from modern pencils.

How can we produce more oil?

In previous experiments, he has added many ways to improve the oil production rate.

For example, high-temperature cooking after freezing will break the soybean cell wall, which will help the oil in the cotyledon be squeezed out; soaking in salt water and stirring at a constant speed will dehydrate the soybean cytoplasm, reduce water impurities and increase oil yield.

But these are not enough.

The final pressing process still requires manual work, and people need to hit the wedges one by one to get out the oil.People will get tired, and to ensure efficiency must increase labor input, so that the cost of soybean oil will inevitably rise.

What he needs is cheap and delicious vegetable oil, which has the advantage of replacing animal oil, and can be quickly transformed and promoted, not just a simple experiment.

"Brother Muye, let's open an oil workshop together."

Ning Shaozi turned around, holding the pen holder with a troubled expression on his face.

"You provide people, I provide technology, and raw materials are empty-handed, so there should be something to earn."

Hearing what he said, the eldest son who was unbuttoning his waist stopped and raised his eyebrows slightly.

"Oil mill?"

"But you want to make soybean oil?"

This is no secret, so Ning Zazi nodded generously.

"Yes, but not only soybean oil, but also various other vegetable oils. Vegetable oil is much cheaper than lard, and the taste is almost the same. With oil and water in everyone's stomach, a lot of food can be saved."

That's the truth.

Feng Kai nodded.

Frontier army drills require physical strength, and the consumption of food and grass has remained high.If there is a stable supply of vegetable oil, not only the bodies of the soldiers can be strong, but it can also solve the food shortage, which is a good idea.

He brought the stool over, sat beside the young man, and asked him softly.

"What do you want to do?"

"I want to build a new oil press."

Ning Fei said softly.

In his previous life, his laboratory had nothing to do with the oil extraction industry, and he had never seen how modern cooking oil is made.

However, as a man of science and technology, he still has basic mechanical knowledge reserves.The wood press in the oil mill is not complicated, combined with the structure of the oil press that I have read in the book, Ning Fei has already drawn a sketch in his mind.

There are not enough people, so water is needed.

The water energy along the Wuzhi River is abundant, such natural resources must not be wasted, and naturally must be well utilized.

He already has hydraulic hammers, water cones, water mills and water blowers, and there may be hydraulic looms in the future, so it would not be surprising to have another hydraulic oil mill.

Water power is the best alternative to human labor, at least in this day and age.

After drawing a rough sketch for Feng Kai, Ning Fei briefly explained the principle of the hydraulic oil press.

Mr. Feng is no stranger to hydraulic machinery. He has personally operated water mills and water hammers, and he knows everything about hydraulic oil presses.

"can."

He nodded.

"As long as you are familiar with it, the operation of this oil press is not difficult. You Shan and Lu Huotou can do it well."

"The frontier army has fought many times in recent times, and many soldiers have been injured and retired. In the past, the imperial court gave money and rewards, but now the three kings are in trouble, and the frontier army can only take care of them."

"Youshan?"

Ning Fei thought of the strong black man with one arm missing.

"How did You Shan get hurt? I saw that he was very hostile to the family."

Hearing his question, Feng Kai didn't hide anything.

"He used to be the instructor in my personal guard camp. When he returned home to get married, he met the ex-empress fleeing. Xue Yiwei hid in the back mountain of his hometown. Killed all."

"When You Shan arrived, he was already powerless. He crippled one of his arms and killed more than a dozen followers of the Xue family. He also seriously injured Xue Yiwei. This can be regarded as revenge."

"It's just that when I came back, I only had half my life left. Now that I'm alone, I naturally hate the family."

Oh, that's it.

Ning Fei nodded, respecting You Shan in awe.

A man, if he wants to be happy with revenge, kill and make decisions, this Youshan is really a good man.

I heard that Empress Xue is holding the jade seal in her hand, but I don't know if this thing is still in Xue's house now.

Ning Fei glanced at the man in front of him, but didn't ask what was on his mind, and instead talked about the oil factory.

"If this is the case, you can let Jiaotou lead the manpower to run the oil factory. With water conservancy to drive the machine operation, it will not take much effort for him."

"In the future, when the oil factory is up and running, and the raw materials are exchanged for oil, the profits should not be underestimated."
