A month later, the first batch of oil presses came off the production line, a few were sent to the oil mill, and the rest were sold.

There is no need to publicize it in newspapers, it will be taken away by the people as soon as it goes offline!

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

Although the common people have never tasted what real soybean oil tastes like, everyone has smelled the fragrance wafting from the oil mill every day, and they are all looking forward to soybean oil!

As long as you own an oil press and open a small oil shop, many people will come to squeeze oil, and there will definitely be an endless stream of business!

Even if there are no people to process it, you can still buy soybeans, squeeze the oil and sell them!

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

When the people learned about this, they immediately took out the soybeans at home, fried them and sent them to the oil mill.

The processing fee is charged per kilogram, and the price is affordable to the common people!

The oil mill works day and night, but it still cannot meet the needs of the people!

There are too many people in Xianyang City who want to extract oil, and the queue has been extended to a month later!

Those people who got the soybean oil ran home happily.

Even if you have just eaten, you should stir-fry a few more vegetables with soybean oil to try out what this thing tastes like!

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

"Hmm! It smells so good!"

The people kept twitching their noses and smelling the attractive fragrance.

After the dishes were cooked, the praises kept coming!

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

“The taste when fried with soybean oil is definitely different!”

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

"The key is that we have soybeans, and we can exchange them for oil with just a little labor money. It's very cost-effective!"

"That's right, our family will eat soybean oil from now on...!"

After tasting the taste of soybean oil, the common people are studying this matter one by one.

Even restaurants have replaced their previous lard with soybean oil.

If someone's house hadn't been changed, the people wouldn't even be able to get in!

After the merchants got the soybean oil, they immediately transported it to other counties by train!

The first batch of oil presses were bought by businessmen in Xianyang without any publicity, and there were none in other counties!

So soybean oil is a very in-demand item in other counties, and you can definitely sell it at a high price if you transport it there!

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

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

People in other counties are also looking forward to eating delicious soybean oil!

After Ying Feiyu left the morning session, he went to the oil press factory to check on the progress.

After walking around twice, accompanied by Huang Yuan, we walked out of the factory gate!

"The weather is really hot!"

After leaving the factory, the scorching sun shone on my face, and beads of sweat immediately oozed out.

The clothes of this era were still very conservative.

Not to mention the robe and coat, it is also wrapped in several layers inside and out!

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

Ying Feiyu complained.

As soon as he finished speaking, he seemed to suddenly think of something.

"I said what's the shortcoming of this car? It turns out it's the air conditioner!"

"Air conditioning? What is that?"

Huang Yuan was puzzled.

"It's just a machine that can cool and heat. It's much more comfortable if there's air conditioning in the car!"

Thinking of this, Ying Feiyu suddenly laughed.

"Can hot and cold be produced?"

Huang Yuan showed an expression of disbelief.

"It's possible, but the conditions are limited now, so I don't know if it can be successful!"

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

He couldn't say whether it would be successful or not. Refrigerant was a big problem!

But don’t worry, you can let them study it first!

The installation of the air conditioner is a trivial matter, you can leave it to Huang Yuan to modify it a little!

But the research on refrigerants will take some time!

This matter must be handed over to the Chinese Academy of Sciences, who will research and manufacture it!

"Then His Highness the Crown Prince can draw out the drawings, and I will have time to lead someone to build it!"

Huang Yuan's interest was immediately aroused when he heard that he could know cold and heat.

"The air conditioner needs a chemical substance. This has to be studied by the Chinese Academy of Sciences! Just wait until they come up with the results and then modify it!"

"That's fine!"

Huang Yuan nodded in agreement.

…

When Ying Feiyu returned to Bieyuan, Chun Yuyi was waiting for him in the main hall.

"Your Highness, the stethoscope you gave me is very useful. Recently, several soldiers were infected with wind and cold. Using it to listen to the sounds in the lungs and airways is much clearer than before, and I can understand the patient's condition better!"

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

Since he stayed in Bieyuan, he often discussed medical matters with Ying Feiyu.

Now he has a certain understanding of Western medicine.

I just don’t understand why this medical technique is called Western medicine!

But there is indeed a lot worth learning about this so-called Western medicine!

Ying Feiyu gave him several detailed diagrams of the human body structure.

From muscles to bones, from internal organs to hair and skin, everything gave him a new understanding!

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

Ying Feiyu also gave him many items in the medicine box for study.

He didn't understand anything else, but the stethoscope really amazed him!

Traditional Chinese medicine pays attention to looking, hearing, asking and feeling.

Once you have a stethoscope, you have another ear to listen to.

You can judge the patient’s condition more accurately!

"Of course!"

Ying Zheng raised his head proudly.

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

"Your Highness, the common people came to you today because they hope to popularize the stethoscope so that every doctor can use it! In the future, it will be more accurate and convenient when diagnosing and treating patients!"

After using a stethoscope, Chun Yuyi discovered that this thing has many benefits. If it becomes popular, it will be of great help to doctors and patients.

“Universalize stethoscopes?”

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

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

Now that Chunyu Yi brought it up, he considered it carefully!

"What? Your Highness the Crown Prince? Is the cost of this thing too high?"

Seeing that His Highness the Crown Prince was silent, Chun Yuyi's heartbeat suddenly accelerated, feeling that he was being abrupt.

They only want to popularize it because it is easy to use, but they never understand the cost!

"That's not true!"

Seeing that his expression was awkward and his cheeks were slightly red, Ying Feiyu smiled and shook his head.

"call……"

Chunyu Yi breathed a long sigh of relief.

"The cost of making a stethoscope is not high, but I was previously focused on other areas and ignored the medical aspect!"

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 mass production of stethoscopes, and only then did Ying Feiyu realize that he had seen the right person!

This kid is not only eager to learn, but also has a kind heart!
