On Suzaku Street in Chang'an City.

It's right next door to Datang Bank.

The red silk cloth on the signboard of the Datang Patent Office was torn off.

Under the onlookers of a group of citizens who came to see the excitement.

Lu Heng made a gesture of invitation to Sun Simiao.

"Old man Sun, please come in, the honor of the patent of Datang No. 00001 will belong to you."

"Hey, I don't want it when you give it to me."

"It's not like you kid doesn't know how busy I am in my day."

"Delay me."

Sun Simiao complained a little dissatisfied, and then followed Lu Heng to the patent office.

The reason why the old man complained so much was because he had not only been teaching a large group of medical students in the academy every day recently.

Even the teachers who teach medical students have to find time to train.

So it's true that as he said, every day is busy, and he has no time to do anything else.

But Lu Heng almost forcibly took him out of the academy this time.

He was asked to attend the opening ceremony of the patent office.

At the same time, he also applied for the honor of the first power of Datang, and also gave him it.

Go to the patent office and sign the documents that the patent office officials have prepared for a long time.

Sun Simiao got a small scroll that was framed like a painting.

That's what he got his patent certificate.

After getting the patent certificate in hand.

Lu Heng dragged Old Man Sun to the door of the patent office again.

Outside the door, these people who were eating melons and watching the excitement announced loudly:

"Ladies and gentlemen in Chang'an City."

"Today, our Datang patent office is open for business."

"I just saw that there are many people who don't know what this patent office does."

"This will just take advantage of the patent applied for by Mr. Sun to tell you about it!"

For Lu Heng, the people in Chang'an City are naturally no strangers.

The people who sent their children to study at colleges outside the city are even more grateful to him.

At this time, I saw that it was Lu Heng who took the initiative to come out and explain the patent office to everyone.

These onlookers couldn't help but quietly gather around and start listening.

Lu Heng took the scroll from Old Man Sun's hand.

Hold it up in your hand so that everyone can see it.

Then he continued to say aloud:

"This thing in my hand is the old man Sun Simiao next to me, that is, the first patent of Datang that you call Sun Shenxian Sun Lao Xian just applied for."

"The content of this patent is also very simple, it is a prescription for typhoid fever."

"It's just that it's different from the prescriptions in the previous medical books."

"This prescription was researched by Old Man Sun himself."

"Not only are the herbs used cheaper, but the effect is also better."

"So Mr. Sun specially took it out this time and applied for a patent."

"In the future, whether it is a traveling doctor who travels all over the world."

"It's still a medical hall in Chang'an City that sits on the ground for consultation."

"You can go to the patent office and look at this prescription."

"Only, albeit according to the regulations of the patent office."

"Every time someone else uses this prescription."

"You have to pay a patent fee to Mr. Sun."

"But Old Man Sun wants to take care of the people in the world."

"Voluntarily reduced the royalty of this patent to a penny."

"That is to say, in the future, those medical halls and traveling doctors, every time you use this prescription when you see a doctor, you only need to pay a penny to Old Man Sun!"

Hearing Lu Heng say this, the onlookers couldn't help it.

They all began to make a fuss at the old man Sun who was standing beside Lu Heng.

And all his mouths were full of thanks for his great kindness,

"Thank you to Doctor Sun, thank you to Doctor Sun for your great kindness."

"Old Sun Immortal is really an immortal."

"Old Sun Immortal has saved countless people, and he will definitely be as blessed as the East China Sea Shoubi Nanshan."

Sun Simiao has practiced medicine for many years, and he is not afraid of being surrounded by so many people to thank him.

At this time, he also stood up at the right time.

Then Lu Heng's words continued:

"I am a mortal, not an immortal as you say."

"But this time, except for this prescription for wind and cold."

"I've already sent other prescriptions that I've developed over the years to the patent office."

"When the time comes, as long as you want to come and see, you can come to the patent office to check it."

"The patent fees for these prescriptions are the same as those for this decoction to cure wind and cold, all of which are only charged for one penny."

"In addition, the old man is here to say one more thing to those doctors who have exclusive medical prescriptions in their hands."

"If you want, you can also come to the patent office to apply for a patent for the medical prescription you have."

"In this way, not only can we receive royalties, but we can also use those medical prescriptions to benefit the world."

"Of course, you all have your own families to support, not like the old man."

"You can charge a little more for the patent fee, and you don't have to follow the old man."

After Sun Simiao finished saying what he wanted to say, he returned the stage to Lu Heng.

And then Lu Heng gave these people a general introduction to the patent office, and then left with Old Man Sun.

Although Lu Heng and Sun Simiao are gone.

However, the crowd in front of the patent office has not dispersed.

Not only that, but many people simply sat down at the nearby tea stalls.

While staring at the bustle at the entrance of the patent office, they began to discuss.

"Hey, you say, what do you want to do when Lu Juma makes such a patent office?"

"What? For the benefit of the world? Didn't you see that Old Doctor Sun took out all the prescriptions in his hand? ”

"In the future, even those unobtrusive Jianghu traveling doctors, as long as they judge the symptoms correctly, they can cure people with the prescription of Sun Lao Immortal?"

"Hmph, you're just lonely, aren't you? The patents issued by this patent office are not only those prescriptions of Old Man Sun. ”

"It is said that even the novelties that Lu Dou made up are all in it."

"Now as long as you are willing to spend money, you can go in and look at the patents and then make those new objects yourself."

After the person who answered the question finished speaking, the people in the entire tea stall couldn't help but look sideways.

Many people hurriedly asked: "Is what you said really false?" I heard that the wine sold in the Little Brother's Restaurant and the glass bottles containing the wine are all made up by Lu Juma, and these are also available in the patent office? ”

"Right? This is all a business that keeps coming in, huh? Can the land colt take it out and make it for someone else? ”

In the face of the doubts of the others, the one who spoke before sneered, and directly raised his head and said to everyone:

"When I bluff you? My wife and brother are working in the patent office! ”

"He told me personally that there are only two people in the patent office who apply for patents."

"One is Old Doctor Sun, and the other is Lu Yuma!"

"As for the drinks you mentioned, I don't know if there are any."

"But my wife and brother told me that Lu Juma had declared several new things that could be used to build houses, and I heard that they were called cement, red bricks, and the like."

"It's the materials that were used to build the houses of the academy."

"If you don't believe me, don't you just ask yourself?"
