The two fragrant and wet kisses fell on Ling Yunfei's face on both sides, and then he took out a few pieces of chalk that he had made.

"Let's play with it, although there is no blackboard, but on this bluestone step, you can also write and draw."

The two of them were like children getting their favorite toys, and they immediately drew there, and it looked like a lot of fun.

Ling Yunfei had already given Song Wenyan the formula of the chalk and asked him to send someone to make it as soon as possible.

I have to say that during this period of time, Song Wenyan of the Ministry of Education was very busy.

......

Three months later, the pulpit in Taizhou School was built, which can accommodate 1,000 people, and in each school, the "Bicycle Principle" written by Ling Yunfei has become a must-have book, but some of the principles in it, not to mention students, even some teaching gentlemen can't figure it out.

This is the reason why Ling Yunfei founded this lecture hall.

The date was set for March 15, and the lecture officially began.

According to Ling Yunfei's request, Song Wenyan invited many gentlemen from various schools, as well as the staff of the Nasmelting Iron Bureau and the Planning Bureau, and most importantly, the workers of the bicycle production plant.

On the 15th of March, the lecture hall was full of people, many of whom were still standing, and Ling Yunfei and the ministers walked in.

Everyone began to bow down, but was rejected by Ling Yunfei.

"Our Shenzhou country, from now on, should worship knowledge, technology, culture, not power, only in this way, our Shenzhou country can endure for a long time and stand at the forefront of the world."

When this sentence was said, everyone was a little confused, but it still broke out into warm applause.

"Come on, bring pen and paper!"

Song Wenyan had already prepared, because he knew that the master was going to write an inscription for this pulpit today.

Ling Yunfei waved his pen: the four big words of the science and technology lecture hall jumped on the paper.

Science and technology forum? There was a lot of talk.

"That's right, only science and technology can make the people of our country happy, only science and technology, can make our country peaceful, only science and technology, we can continue to explore, there are many things in science and technology, today, we start with bicycles, every day in the first half of the day and half a day each class, please take good notes, below, we will talk."

Ling Yunfei turned around and saw the blackboard, he was very happy, holding a chalk and writing on it: The principle of the bicycle's bars.

Everyone was stunned, just such a white thing, it could be written, and it was so beautiful.

"Students, teachers and gentlemen, what is the principle of leverage, let me help you demonstrate."

Song Wenyan took a long thick wooden stick, and then took a wooden pier pad and put it underneath.

"How to use a small force to move a big thing, this is to use the lever principle, to put it bluntly, our chopsticks are using the lever principle, the following students, please see, I can use my own strength, move this big lion, do you believe it?"

The crowd began to talk, and a bold child stood up.

"Mr. President, are you bragging?"

When this kid said this, everyone was stunned, and it was a crime of deception to speak so disrespectfully.

Ling Yunfei didn't get angry, but said loudly: "Come, everyone, give applause to this little kid." ”

The crowd didn't know what was going on, so they could only applaud.

"He's done a great job, the first step of science is to question, and then to break the doubt, you know? And in the future, you can not regard me as the president, teach you knowledge, you can call me a professor, here, there is only science and technology and knowledge, there are no kings, kings and ministers, officials and people, understand? ”

Everyone nodded, they didn't expect their president to be so close to the people.

"Let me ask again, if you don't believe I can lift that lion alone, please raise your hand."

With Ling Yunfei's encouragement, almost everyone raised their hands.

"President, no, professor, will there be danger, that lion, it looks like no less than a thousand pounds, you are so thin, there will be no danger."

Ling Yunfei smiled: "Don't worry about me, below, I will prove to you what is the power of science and technology, what is the power of leverage." ”

Ling Yunfei asked people to put an iron chain around the stone lion, and the other end was hung on one end of the long wooden stick, allowing Song Wenyan to move the wood of the fulcrum forward and make a lever.

"Next, I'll show you a lions by one person."

The other end was a little high, and Ling Yunfei brought a ladder and climbed up.

Then he grabbed the stick with both hands, and fell, and the lion was hanged.

"Get up, oh my God!"

"How is it possible that the two weights are so far apart?"

......

Suddenly, there was a lot of discussion in the pulpit.

Ling Yun flew down: "It's not just me, you can do it too." ”

Ling Yunfei called up a little child and asked Song Wenyan to continue to move the fulcrum towards the lion, and the little child pulled up the lion very lightly.

The crowd thought it was incredible.

Ling Yunfei began to teach the principle of levers on the blackboard, and taught in such an easy-to-understand way, and the people below listened to it with relish.

......

It took more than a month for Ling Yunfei to teach all the principles of his bicycle, and then these people returned to their respective places with knowledge.

Song Wenyan and Zhou Shiqiang came to report that the newly built bicycle industry began to produce, and soon the first bicycle would be produced.

Ling Yunfei looked at the happy appearance of the two of them, and said slowly: "Don't be too happy, have you ever thought that one day, just like that bicycle, we will move by ourselves without manpower, do you believe it?" ”

"Master? No, Professor. ”

Ling Yunfei stipulated to these people that they should call him professor wherever they were near the school.

"Professor, this is too impossible, if there is no external force, how can it be."

Zhou Shiqiang interrupted: "I think it will, professor, if you get the sails of a sailboat on the bicycle, then you won't need manpower." ”

Ling Yunfei nodded, very satisfied:

"Very good, you are finally learning to think now, but let's take our time, the problem now is, you are writing too slowly, I have to change the way you write."

"Writing?"

"This is very easy, the previous mining bureau mined stone and found graphite, I can make pencils, of course, the previous weaving cloth has dyes, I can also make fountain pens, so that my country's universities, writing is easier."

Resolute and resolute, do what he says, Song Wenyan has to be with the professor when he says anything, and he has a great interest in what he says with the professor.

Ling Yunfei did not refuse, took Song Wenyan and found Lao Qiu together.

Ling Yunfei brought graphite, asked Lao Qiu to polish the thickness consistently, surrounded the wood chips around the graphite, and pressed them with glue.

In this way, the first pencil of the Shenzhou Kingdom was manufactured.

Ling Yunfei sharpened it with a knife and wrote his name on the paper.

"Come on, you guys try it too."

That Song Wenyan stepped forward and tried it, and it was really good, but he still grabbed the pencil with the posture of a brush.

"It's more comfortable to hold the pen like this."

Ling Yunfei demonstrated, sure enough, it was good, and Lao Qiu gave Ling Yunfei a thumbs up.

"My Lao Qiu is not wrong, not only the first Yan Emperor of the Tang Dynasty, but also a great inventor, this thing was given to the student, the student must die of happiness, and he is not afraid of the ink spilling everywhere."

Song Wenyan also nodded, happy like a child.

"Let's do it, let's call it the Shenzhou pencil, and when our country uses it, we can export more to Datang or other countries to increase our income."

When Song Wenyan heard it, he immediately nodded and took action.

Besides, the structure of this fountain pen is a bit complicated, but Ling Yunfei said the structure of his fountain pen, and Lao Qiu was able to make the nib so fine.

Ling Yunfei was simply stunned:

"Lao Qiu, you are the great craftsman of my Shenzhou Country."

Seeing Ling Yunfei praise like this, Lao Qiu burst into tears: "I, an old horse, met Bole today." ”

Ling Yunfei patted Lao Qiu's shoulder, Lao Qiu, this fountain pen is made, you have to put the word "Lao Qiu" on the tip of the pen, it is called Lao Qiu brand fountain pen. ”

Lao Qiu didn't know what to say, so he knelt down for Ling Yunfei at once.

Ling Yunfei immediately helped him up: "Don't be like this in the future." ”

Lao Qiu wiped his tears of happiness: "You can give me this tip." ”

......

A month later, the ministers all got the first batch of Lao Qiu brand fountain pens, and two months later, the schools in the whole Shenzhou country began to popularize pencils and pens.

Such a convenient writing makes people applaud again and again.

At this moment, Zhou Shiqiang came to report that the first batch of bicycles, twenty units, had been assembled and were about to start testing.

According to Ling Yunfei's plan, they displayed the twenty brand-new painted bicycles on the square in front of Taizhou University.

As soon as it was put on it, it attracted countless people to watch, and everyone didn't know what it was.

At this moment, Ling Yunfei did not tell Yun Ge and Yun Yun the news, and quietly came to the room of the two.

"Yunge, I have to ask you to do me a favor."

"What's the busy?"

"I can't tell you right now, but it's going to be fun, and if you play it well, it's really exciting."

Yunyun pouted: "What, is there no me?" ”

Ling Yunfei scratched his head and hugged Yunyun with his hand: "It's not that I'm biased, this thing is really only me and Yun Gehui, you won't be able to do it for the time being." ”

Yunyun smiled flatteringly: "Huh? That boudoir ninety-nine, I don't have it, what posture I can't be, could it be that you and Yun Ge hid it from me and created a new posture? Hmph, don't tell me yet. ”

When Ling Yunfei heard this, he was amused and shy:

"Oh, Yunyun, you want to be crooked, it's not this, it's really not this, it's a bicycle."

Ling Yunfei originally wanted to surprise the two, but Yunyun thought crookedly, so he had to say it.

"You built a bicycle?"

"Not only have they been built, there are twenty of them!"

"Twenty, I haven't played in a long time, I want to play."

"I'm going to play too, even though I can't, I can learn."

Ling Yunfei pinched Yunyun's nose: "Of course, when Yunge and I went to the square, we just want to teach most people to learn, how can there be less of you!" ”

Yunyun that happy.

At this time, Ling Yunfei began to smile evilly: "If I can have twenty cars, there will be two hundred, and there will be two million and twenty thousand vehicles, what about what you two promised me?" ”

The two were shy:

"If it's true, you can do whatever you want."

The three of them just hugged each other, Ling Yunfei was comfortable and happy, there was a way:

Hug the waist of the beautiful woman on the left and right, and refresh the two treasures of the human body.

The side faces kiss and rely on each other, and the three of them are happy to be taotao.
