After Ying Feiyu promised Chun Yuyi to develop medicine and manufacture stethoscopes, he drew the drawings and used the system to exchange for a stethoscope and sent it to Huang Yuan for him to watch and study!

After this period of research, the results are finally available!

"His Royal Highness the Crown Prince's stethoscope has been successfully manufactured, you can see if it meets the standards!"

How does Huang Yuan understand these instruments? It's just made according to the drawings and compared with the samples taken.

Ying Feiyu took the stethoscope that Huang Yuan had just built and compared it with the system exchange, and there was almost no difference in appearance.

Then he put one end of the stethoscope on his chest and the other end on his ear.

Tried both, the difference wasn't huge!

"Hmmm! There are still minor differences, but it's okay! ”

Ying Feiyu nodded in satisfaction.

After all, the level of science and technology in this era is not as accurate as that of later generations.

Being able to do this level is beyond his expectations!

"Go and call Chun Yuyi!"

Confirming that the stethoscope could be manufactured, Ying Feiyu immediately gave an order to the guards outside the door.

Chun Yu cares about that guy, I hope to popularize the stethoscope, if you know that the stethoscope is made, you must be happy!

"Yes!"

When the guards heard this, they immediately went to do it.

"...... do you care?"

Hearing this name, Huang Yuan tilted his head slightly, as if searching for this person in his mind.

After a while, he seemed to think of something, and asked suspiciously, "His Royal Highness the Prince, this is Chun Yuyi, but that apprentice of Gongcheng Yangqing?" ”

"You know him, too?"

This surprised Ying Feiyu very much.

The name of Gongcheng Yangqing is resounding in Xianyang City, and even in the entire Great Qin.

But his apprentices may not.

Not many people know!

"Just heard of it! It is said that Gongcheng Yangqing taught this apprentice everything he had learned all his life, and this apprentice was also very smart and learned ...... quickly! ”

Although Huang Yuan shuttles between factories all day long, he has little time to learn about those things in the people.

But I usually listen to the small talk of the workers, and I will also mention all kinds of new things in the city.

"It is said that Gongcheng Yangqing has traveled all over the world and handed over the entire medical hall to Chun Yuyi, but he closed the medical hall, and no one knows where to go! It turned out to be in the palace of His Royal Highness the Prince! ”

Huang Yuan couldn't laugh or cry.

"That's right! Before, the prince was assassinated by the man in black and injured Rosa, so he went to him for medical treatment, during which the prince used some medical methods and was seen by that kid! After the public ride Yangqing Cloud Tour, he came to the other garden to treat the soldiers! ”

"I got this stethoscope some time ago, and I hope it can be mass-produced, and then I put forward a lot of ideas, including the establishment of a medical school!"

Huang Yuan is his own person, and Ying Feiyu did not hide it, and roughly explained the ins and outs of the matter.

"Haha! I see......! ”

When Huang Yuan heard this, he laughed approvingly, "It's rare that someone is willing to study medical skills and think about the people of the world!" ”

"Yes! Daqin is developing in all aspects, but medical care is too backward, and it is indeed time to develop! ”

Ying Feiyu nodded.

"His Royal Highness the Crown Prince, are you looking for me?"

While the two were talking, Chun Yuyi stepped in and arched his hand slightly.

"That's right......!"

Ying Feiyu nodded, and handed the freshly made stethoscope to Chun Yuyi along with the samples sent over, "What is the difference between these two?" ”

"Stethoscopes built?"

After seeing the two stethoscopes, Chun Yuyi's eyes suddenly lit up.

"Hmmm! If it doesn't work, you can see first! ”

Ying Feiyu nodded.

"Good!"

At the beginning, Chun Yuyi also began to distinguish from the appearance.

Once you're sure there's no difference, start testing!

Like Ying Feiyu, he also put a stethoscope on his chest and carefully distinguished the test.

After a moment, he held one of them up, "Your Highness the Prince, if the grass people are not mistaken, this should have been made by Lord Huang just now, right?" ”

Huang Yuan is a celebrity in Xianyang City, almost everyone knows about it, and no one knows it.

Many things in the lives of the people are closely related to him!

So I was not too surprised to see him in the hall just now!

He is in charge of many industries, and it is normal for him to come to His Royal Highness the Crown Prince from time to time to pay tribute!

It's just that I didn't expect that this time it was a stethoscope!

"Hahaha! That's right! ”

was accurately picked out by him, and Ying Feiyu laughed happily.

This proves that this kid's medical skills are really good, and he can distinguish such subtle differences!

"He is worthy of being a proud disciple of Gongcheng Yangqing, and he really deserves his reputation!"

Huang Yuan was also full of praise.

"Lord Huang praised it falsely!"

Chun Yuyi modestly arched his hand.

"I wonder how you can tell the difference?"

Huang Yuan asked.

"Since Lord Huang asked, please forgive the grass people for offending ......!"

Chun Yuyi gave his hand again, "These two stethoscopes are the same in appearance, but when they are applied, there are very slight differences!" But it's already very good, and it helps a lot in the diagnosis and treatment! ”

knew that these words might offend Huang Yuan, but he still chose to tell the truth.

"Hahaha!"

After Huang Yuan heard this, not only did he not get angry, but laughed.

"Isn't Lord Huang angry?"

"Hahaha! What's there to be angry about? You and His Royal Highness the Crown Prince just commented almost exactly the same! ”

The evaluation of Ying Feiyu just now is also slightly different, but it does not affect the use.

"It's a fact!"

Chun Yuyi smiled slightly.

"Haha, okay, turn around and relax, I'll take the craftsmen to study it carefully and strive to do better!"

"No, that's already good! Looking back, Prince Ben has other things for you to make! ”

Huang Yuan planned to improve it again, but was stopped by Ying Feiyu.

There are so many things that Daqin needs to make now, and he can't always stay on the stethoscope!

According to his plan, it is enough to make things.

As for development, it is left to the people of today.

Give them a space to play, and not everything can be studied by him alone.

Everyone is waiting to use ready-made, which limits the idea, but affects the development of Daqin in the future!

We have to leave a space for the people of the world!

"Yes!"

Huang Yuan nodded in agreement.

"That'...... Can stethoscopes be mass-produced? ”

"Build! But you don't have to build a factory! Open a workshop in an existing factory and produce small quantities! ”

Stethoscopes aren't essential for everyone, so the demand is minimal.

And this thing is not a consumable, a stethoscope can be used for years, or even more than ten years.

So there is no need to put a large number of craftsmen on this and waste resources.

As long as it is produced in small quantities, the supply can be gradually satisfied!

"Yes!"

Huang Yuan agreed.

"The grass people thank His Royal Highness the Crown Prince for the world, Langzhong and the people!"

The manufacture of the stethoscope is a good thing for Langzhong and the people, and Chun Yuyi is excited.

"There is no need to thank you, the stethoscope made by this prince is also sold to the outside world, and it is not given away for free for charity!"

Ying Feiyu waved his hand.

Although the stethoscope object is small, it also has a cost, and he cannot give it away for free for a long time.

Aren't all the people in the world swarming to receive it?

"This grass folk naturally knows that as long as the stethoscope is studied, it will already be a great thing for the people of Daqin!"

Chun Yuyi gave up his hand again.

With a stethoscope, many conditions can be diagnosed more carefully without delaying the condition.

Symptomatic treatment, the people spend less money and suffer less crime!

"Okay!"

This kid wanted to thank him, but Ying Feiyu couldn't shirk it, so he had to accept it happily.
