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

After this period of research, we finally have the results!

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

How does Huang Yuan know about these instruments? He just made them according to the drawings and compared them with the samples he brought.

Ying Feiyu took the stethoscope Huang Yuan had just made and compared it with the one exchanged by the system. 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.

I tried both and the difference is not big!

"Yeah! Although there are still slight differences, it's okay!"

Ying Feiyu nodded with satisfaction.

After all, the technological level of this era is not as precise as that of later generations.

Being able to achieve this level was beyond his expectation!

"Go and call Chun Yuyi!"

After confirming that the stethoscope could be manufactured, Ying Feiyu immediately gave orders to the guards outside the door.

Chunyu Yi, that guy, has always wanted to popularize the stethoscope. If he knew that the stethoscope was ready, he would be happy!

"yes!"

The guard heard the sound and went to do it immediately.

"Chun Yuyi...?"

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

After a moment, he seemed to have thought of something and asked suspiciously, "Your Highness, is this Chun Yuyi the disciple of Gongcheng Yangqing?"

"You know him too?"

This surprised Ying Feiyu.

Gongcheng Yangqing's name is resounding in Xianyang City and even in the entire Qin Dynasty.

But the same cannot be said for his apprentice.

Not many people should know!

"I just heard about it! It is said that Gongcheng Yangqing taught this apprentice everything he had learned in his life, and this apprentice was also very smart and learned very quickly...!"

Although Huang Yuan shuttles between factories all day long, he doesn't have much time to understand folklore.

But I usually listen to the workers chatting and mention various new things in the city.

"It is said that Gongcheng Yangqing has traveled far and wide and handed over the entire medical clinic to Chunyu Yi, but he closed the medical clinic and no one knows where he is! It turns out that it is in the palace of His Highness the Crown Prince!"

Huang Yuan didn't know whether to laugh or cry.

"That's right! The prince was assassinated by a man in black before and injured Rosa, so he went to him for treatment. During this period, the prince used some medical methods, which was seen by that boy! After traveling around in Yangqing, he came here

Go to the Bieyuan to diagnose and treat the soldiers!"

"I got this stethoscope some time ago. It's so precious. I hope it can be mass-produced. Then I put forward many ideas, including the establishment of a medical school!"

Huang Yuan was one of his own, so Ying Feiyu didn't hide anything and roughly told the whole story.

"Haha! That's it...!"

Huang Yuan heard this and laughed in agreement, "It's rare for someone to study medicine and think about the people of the world!"

"Yes! Great Qin is developing in all aspects, but medical care is really too backward. It really needs to develop!"

Ying Feiyu nodded.

"Your Highness, are you looking for me?"

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

"That's right...!"

Ying Feiyu nodded and handed the newly made stethoscope and the sample to Chun Yuyi, "Do you see the difference between these two?"

"Is the stethoscope ready?"

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

"Well! You have to wait and see whether it will succeed or not!"

Ying Feiyu nodded.

"good!"

Chunyu Yi first started to distinguish from the appearance.

After confirming that there is no difference, start testing!

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

After a moment, he lifted one of them up and said, "Your Highness, if the common people guessed correctly, this should have been built by Mr. Huang just now, right?"

Huang Yuan is a famous person in Xianyang City, and almost everyone knows about him.

Many things in people's lives are closely related to him!

So when I saw him in the hall just now, I wasn’t too surprised!

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

I just didn’t expect that what I built this time was actually a stethoscope!

"Hahaha! That's right!"

Being picked out by him accurately, Ying Feiyu laughed happily.

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

"As expected of Gongcheng Yangqing's proud disciple, he truly deserves his reputation!"

Huang Yuan was also full of praise.

"Master Huang is so complimentary!"

Chunyu Yi modestly bowed his hand.

"I wonder how to distinguish the two?"

Huang Yuan asked.

"Since Mr. Huang asked, please forgive the common people for offending...!"

Chun Yuyi handed over his hand again, "These two stethoscopes are the same in appearance, but there are subtle differences in their application! But they are already very good and will be of great help in diagnosis and treatment!"

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

"Hahaha!"

After Huang Yuan heard this, not only was he not angry, he actually laughed.

"Isn't Mr. Huang angry?"

"Hahaha! What's there to be angry about? The comments you and His Royal Highness just made are almost exactly the same!"

Ying Feiyu's evaluation just now is also slightly different, but it does not affect its use.

"This is a fact!"

Chunyu Yi smiled slightly.

"Haha, okay. When I have time, I will take the craftsmen to study it carefully and strive to make it better!"

"No need, this is already good! Now that I have some free time, I have 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 manufacture now, and it can’t just stay with the stethoscope!

It is enough to build things according to his plan.

As for development, leave it to the current people.

Give them a space to develop. He cannot study everything by himself.

Everyone is waiting to use what is ready-made, which limits their ideas and will actually affect the future development of Great Qin!

We must leave a space for the people of the world!

"yes!"

Huang Yuan nodded in agreement.

"Then... stethoscopes need to be manufactured in large quantities?"

"Made! But there is no need to build a special factory! Just open a workshop in the existing factory and produce in small quantities!"

Stethoscopes are not essential for everyone, so the demand is very small.
