A month later, the first batch of oil presses rolled off the production line, and a few were arranged to go to the oil mill, and the rest were sold to the outside world.

You don't have to advertise it in the newspapers, you will be pulled away by the people as soon as you go offline!

The businessman who planned to do this business always kept an eye on the production progress of the machine, and after it was built, he asked the price and bought it immediately!

Although the people have never tasted the taste of real soybean oil, everyone smells the fragrance wafting from the oil mill every day, and they are very much looking forward to soybean oil!

As long as you have an oil press and open a small oil mill, there will be many people who will come to extract oil, and the business will definitely be endless!

Even if there are no people to process it, you can buy soybean oil and sell it yourself!

For a time, there were many oil mills in Xianyang City.

When the people learned of this, they immediately took out the soybeans from their homes, fried them and sent them to the oil mill.

The processing fee is charged by the catty, and the price is affordable for the people!

The oil mill is working day and night, and it still can't supply the needs of the people!

There are too many people in Xianyang City to squeeze oil, and it has been lined up for a month!

The people who got the soybean oil ran home happily.

Even if you've just eaten, stir-fry a few more dishes in soybean oil to get a taste of what it tastes like!

As soon as the soybean oil is poured into the hot pan, the smell of cooked beans spreads!

"Hmmm! It's so fragrant! ”

The people kept twitching their noses and smelling the enticing scent.

After the dish is fried, it is even more praised!

The whole family gathered around a pot of fried potatoes and ate with relish!

"The taste of stir-fried soybean oil is definitely different!"

"Yes! It doesn't have that special smell of animal fat! ”

"The key is that we have soybeans, as long as you get some labor fees, you can exchange them for oil, which is very cost-effective!"

"That's right, our family will eat soybean oil in the future......!"

Having tasted the taste of soybean oil, the people are studying the matter one by one.

Even restaurants have replaced their previous lard with soybean oil.

If anyone's house is not changed, the people will not even enter the door!

As soon as the merchants got their hands on the soybean oil, they immediately transported it by train to other counties!

The first batch of oil presses were bought by merchants in Xianyang without publicity, and there were no other counties at all!

Therefore, soybean oil is a very sought-after thing in other counties, and it can definitely be sold at a high price when it is shipped over!

By the time the second batch of oil presses was built, the weather was already very hot, and the oil yield was even higher than before!

This time, many people from other counties came to buy and prepare to open oil mills in their hometowns.

The people of other counties are also full of anticipation, waiting to eat delicious soybean oil!

After Ying Feiyu got off the morning court, he went to the oil press factory to check the progress.

After turning around twice, accompanied by Huang Yuan, I walked out of the gate of the factory!

"It's really hot!"

Out of the factory, the scorching sun shone on his face, and fine beads of sweat immediately seeped out.

The clothes of this era were still very conservative.

Not to mention the robe and coat, there are several layers of wrapping inside and out!

"yes, driving in this weather is like a big steamer!"

Ying Feiyu said complainingly.

As soon as the words fell, he seemed to suddenly think of something.

"I said what is the disadvantage of this car, it turns out to be an air conditioner!"

"Air conditioning? What's that? ”

Huang Yuan was puzzled.

"It's a machine that can cool and heat, and with air conditioning in the car, it's much more comfortable!"

Thinking of this, Ying Feiyu suddenly laughed.

"Can hot and cold still be made?"

Huang Yuan showed an expression of disbelief.

"Yes, yes, but now the conditions are limited, and I don't know if I can succeed!"

Air conditioning was very common in later generations, but it was the first time in this era.

Whether it will succeed or not is not easy to say, refrigerant is a big problem!

But there's no hurry, you can let them study it first!

The installation of the air conditioner is a trivial matter, and it can be handed over to Huang Yuan to be slightly modified!

Refrigerant research will take some time!

This matter has to be handed over to the Chinese Academy of Sciences, and they will research and manufacture!

"Then His Royal Highness the Crown Prince can draw out the drawings, and the lower officials have to take the people to see it!"

I heard that I could know cold and hot, which immediately aroused Huang Yuan's interest.

"Air conditioners need a chemical substance in them, and this has to be studied by the Chinese Academy of Sciences! Wait for the results of their research and then transform it! ”

"It's good!"

Huang Yuan nodded in agreement.

……

Ying Feiyu returned to the other garden, and Chun Yuyi was waiting for him in the main hall.

"Your Royal Highness the Prince, this stethoscope you gave me is so easy to use, recently several soldiers have been infected with wind cold, use him to listen to the sound in the lungs and airways, much clearer than before, and can better understand the patient's situation!"

After seeing Ying Feiyu, Chun Yuyi smiled with surprise on his face.

Since he stayed in the other garden, he often talked to Ying Feiyu about medical matters.

Now he has a certain understanding of Western medicine.

I just don't understand why this kind of medicine is called Western medicine!

However, this so-called Western medicine does have a lot to learn!

Ying Feiyu gave him several detailed drawings of the human body.

From muscles to bones, from internal organs to hair and skin, he has a new understanding!

In the past, I learned all about acupuncture points, but now I know that there is still a lot of knowledge in the human body!

Ying Feiyu also handed over a lot of things in the medicine box to him for study.

The rest is not used yet, but the stethoscope really amazes him!

Traditional Chinese medicine is about seeing, hearing, and inquiring.

With a stethoscope, there is one more listening.

You can judge the patient's condition more accurately!

"Of course!"

Ying Zheng tilted his head proudly.

If this thing is useless, how can every doctor have one around his neck in the future?

"His Royal Highness the Prince, the grass people came to you today in the hope that the stethoscope can be popularized so that everyone can use it! In the future, when treating patients, it can be more accurate and convenient! ”

After using the stethoscope, Chun Yuyi found that this thing has a lot of benefits, and if it is popularized, it will be of great help to Lang Zhong and the patient.

"Popularizing stethoscopes?"

Ying Zheng's eyes rolled back and forth, and he began to think.

There was no suitable person to popularize medical care before, and he didn't think about it.

Now that Chun Yuyi brought it up, he thought about it carefully!

"What? His Royal Highness the Crown Prince? Is this thing too expensive? ”

Seeing that His Royal Highness the Crown Prince didn't speak, Chun Yuyi's heartbeat suddenly accelerated, and he felt that he was abrupt.

I just want to use it and ask for popularization, but I don't understand the cost!

"Not really!"

Seeing that his expression was cramped, and his cheeks were slightly red, Ying Feiyu shook his head with a smile.

"Hoo ......"

Chun Yuyi breathed a long sigh of relief.

"The cost of the stethoscope is not high, but Prince Ben used to focus on other places and ignored the medical treatment!"

Ying Feiyu admitted very generously.

The most important thing is that there are no suitable people around to develop this area!

Today, Chun Yuyi proposed to mass-produce a stethoscope, and Ying Feiyu realized that he was not looking at the wrong person!

This kid is not only studious, but also has a loving heart!

I found something useful to use, not to hide it privately, but to propose mass production, so that all Langzhong in Daqin can use it!
