The hot air balloon drifted farther and farther away, and some people on the ground could no longer see it, so they wanted to chase it again. After all, this is the first person to fly in the air, and such a spectacle is completely worth seeing for a while.

However, the soldiers who maintained order in the streets did not withdraw. Seeing that someone was about to move, they all admonished: "The flying ceremony is not over yet, and no one is allowed to move." ”

This walkaround, naturally, means that you can't leave through the street. Going to the toilet or something, naturally, is not in this case.

Those who wanted to chase after the people heard that the flying ceremony was not over, that is, there was a follow-up, so they had to continue to wait in place. They are a little strange, the hot air balloon has already floated away, this is not over yet, is it going to float back again?

Waiting was a boring thing, and the people of Ying Tianfu on the side of the Qilin Gate began to talk about what they had just seen.

"What kind of couplet is that, I don't know who wrote it, can I write a couplet, and I'm embarrassed to take it out in front of the public!"

"Do people say it's a couplet? Stupid! There's nothing you can't do, only the unthinkable! This sentence is so domineering! ”

"That's reasonable, if you think about it, a few people dare to think about this flying thing, but now you look at it, people can do it! This carpenter Xu is really amazing! ”

"Isn't it amazing? People are the apprentices of the emperor today, do you say that you have no ability, can you become the emperor's apprentice? With the emperor's guidance, why can't you do it? ”

"Science and technology power, science and technology change the world!" Speaking of which, it seems to be true! Even something like flying can be done, so what else can't be done? ”

"Where are the books on science and technology? I'm going to see it too, maybe I have a great invention too! ”

“……”

There are almost no exceptions, whether it is the princes and ministers or the ordinary people, their discussion begins with that couplet. It's really this couplet that is so eye-catching that it is displayed on the much-anticipated balloon. It can be said that it is the most appropriate time, the most appropriate place.

If it is said that in the past, under the intentional guidance of some readers, this scientific and technological knowledge was regarded as the learning of craftsmen and considered to be lowly knowledge, after the shock and propaganda of this scene just now, especially the finishing touch of those two slogans, this scientific and technological knowledge has been unconsciously raised to a very high level. Think about it, "science and technology power, science and technology change the world", so what could be more powerful than this?

Many people's thoughts at this time are to immediately find the science and technology series promoted by the imperial court, read it carefully, and see if they can find anything from it, and they can do such a high-profile thing! Everyone believes that a big event like this will be passed down through the ages!

Among them, there are even many female dependents of dignitaries. They basically don't go out of the door, and they don't step out of the second door. In the past, most of them were piano, chess, calligraphy and painting, and I had seen such a new thing after being locked in the boudoir for a long time. Therefore, there is a lot of thinking in my heart, and I also want to see what this scientific and technological knowledge is like. As a result, Marie Curie of the Ming Dynasty already had seeds, waiting for them to take root and blossom in the future.

On Emperor Chongzhen's side, Xu Zhengming was his apprentice, and the science and technology series was compiled by him. Among these high-ranking officials around him, there are already people who have begun to contribute achievement points.

This can prove that at this time, some of these officials congratulated Emperor Chongzhen and patted Emperor Chongzhen on the back, which was indeed sincere. In this regard, Emperor Chongzhen paid a little attention to it, which people have contribution achievement value, and which people do not contribute achievement value?

Some people can't see the balloon anymore, but some people can see it. The people who can see it have been broadcasting the situation of the hot air balloon live, and from time to time they say that they are floating there. So, in their discussion, there was a different content. is nothing more than Xu Zhengming, who floated past Ying Tianfu, what kind of scene would he see in Ying Tianfu? It should be beautiful, right? The inner city and the Forbidden City are all beautiful, right? Did you see anything you shouldn't see? Isn't it fun or something?

Therefore, those who have money have an impulse to go up to the sky to see, what kind of scene will it be to see the earth from the sky? These people are not short of money, and they have even thought about it, and when they turn around, they will spend money to make one out, isn't it a huge Kong Ming lantern? Do it a few more times, and if you don't get it, you can make it yourself!

Finally, it was rumored that the hot air balloon had floated over Ying Tianfu and landed outside the city. So, some people wanted to leave again, wanted to go and see, but the soldiers on the street had not allowed the pass, and the flying ceremony was still not over, so everyone had to wait helplessly, and they were also a little curious, not knowing what else would follow?

In the process of waiting, they have talked about the hot air balloon itself. Now when I am waiting, I am mostly talking about the story behind the hot air balloon, such as how Xu Zhengming was accepted as an apprentice by the emperor? Where did the emperor learn about science and technology? How powerful is this scientific and technological knowledge, and so on.

The effect of everyone getting together to chat is incomparable to any other form of publicity. This has a very big impact on arousing the interest of the public. Amid their discussion, finally, there was movement in the distance of the street.

A fast horse came galloping, or rather, the horse was not running fast, but was running. The reason for this is because the knight on the horse should be a novice and not good at riding. As he rode, he shouted loudly: "Master, the apprentice has done it!" ”

"Master, the apprentice has succeeded!"

"Master, apprentices can make more powerful airships!"

“……”

Hearing this shout, everyone knew that this knight was the Xu Zhengming who was in the sky just now. He managed to fall to the ground, and this is the coming of the good news!

Hey, wait, he's giving good news to his master. Isn't his master the current emperor? Could it be that the emperor is actually in Yingtianfu? Otherwise, what's the point of him yelling like this?

Thinking about it like this, everyone was immediately shocked. Could it be, the emperor, who is far away in Beijing, must have really arrived at Yingtianfu, right?

For the emperor, the people of Ying Tianfu have always been more regretful. You must know that after the founding of the Ming Dynasty, the capital of the country was chosen in Yingtianfu! In the past, they were the people of the Ming Dynasty at the feet of the Son of Heaven! But since they became ancestors, they have lost this pride.

At this time, it was understood that the emperor might be in Yingtianfu, and all the people stretched their necks one by one, and even looked at each other, where would the emperor be?

In this way, Xu Zhengming is once again in the limelight. Everyone knows that Xu Zhengming reported good news to his master, and as long as he looked at him, he could see where the emperor was!

Of course, there are some people who have already guessed it. If the emperor is really here, he should be at the head of Qilin Gate, right?

However, there were no people in the emperor's clothes!

"Master, the apprentice's hot air balloon test has been successful, and he can make an airship!"

"Master, instruct the apprentices to make the airship!"

“……”

When approaching the Qilin Gate, Xu Zhengming shouted every word with the eyes of "airship". This made the people of Ying Tianfu who heard it immediately pay attention, airship? What airship?

If the hot air balloon is in their eyes, it is actually very ordinary, after all, there are examples of Kong Ming lanterns. can listen to Xu Zhengming say that he has succeeded in making a hot air balloon, and after he can fly, he can make an airship. Obviously, this airship was supposed to be something more powerful and could fly. At this time, in their minds, they couldn't imagine what happened to this airship? Suddenly, the enigmatic airship successfully attracted their attention.

When they were thinking about this, they saw Xu Zhengming dismount when he rode to the city of Qilin Gate, and then he raised his head under the city, looked at the city, knelt on the ground, and shouted: "Master, under your guidance, the apprentice has become the first person to fly in the sky since ancient times!" The wish of the disciples has been realized, and there are no regrets in this life! ”

Xu Zhengming's words are really his heartfelt words. Now, of course, this is just his first dream, and he has decided in his heart that he wants to work hard for his second dream, which is to build an airship.

Above and below the city, on the roofs and on the ground, almost everyone saw this situation and stared at the city. They thought, look at it like this, the emperor has really come to Yingtianfu! If someone stands up and replies, that person must be the current emperor!

Under the watchful eye of all the people, Emperor Chongzhen was still only dressed in civilian clothes, close to the battlements, looked down at Xu Zhengming below, and said in a loud voice: "I am very relieved that you can make a safe flight hot air balloon as scheduled under my guidance!" ”

When these people near the Qilin Gate saw Emperor Chongzhen appear, they found that they seemed to be a little familiar, and then they remembered. Isn't this the young man who took two women and walked all the way in front of him!

Just as they were thinking like this, they heard Emperor Chongzhen's words, and at this time, there was no doubt that this young man must be the current emperor!

As if to verify the thoughts in their hearts, they saw that the high-ranking officials of the court who came out with the emperor on the city had already knelt on the ground to salute: "Long live my emperor, long live, long live!" ”

Immediately afterwards, the soldiers at the head of the city, all facing the emperor's position at the head of the Qilin Gate, knelt down on one knee and saluted in unison: "Long live my emperor, long live, long live!" ”

The Emperor is coming!

Wherever the people were, they all shouted long live.

Some people looked at the emperor at the head of the city, and suddenly had an idea in their hearts: If they could see the emperor often, or say that the emperor would be resident in Yingtianfu in the future, how good would it be!

Emperor Chongzhen was already accustomed to seeing big scenes, and after everyone saluted, he raised his hand to signal everyone to calm down, and then said loudly: "Everyone has seen today that hot air balloons can take people to fly in the sky, just like your common Kong Ming lantern." However, I want to tell you that this large Kong Ming lantern is not easy to make! ”

The hot air balloon demonstration is a big event that just happened, and many people have the idea of doing it themselves. At this time, I heard that the instructor of the hot air balloon, that is, Emperor Chongzhen, personally explained the matter about the hot air balloon, which immediately attracted everyone's attention.

"Before I talk about this, I have a question for you, why do people have to walk on the earth and not float to the sky? Why do apples on the tree fall to the ground and not to the sky when they are ripe? Why ......"

Hearing Emperor Chongzhen's words, everyone was stunned, isn't this something that everyone knows? Why do you still need to ask? Under normal circumstances, if an ordinary person asks such a question, and the person who hears it gives a "neurotic" comment, then he will not let the question go through his mind at all.

But at this time, it was different, because this question was asked by Emperor Ming after the demonstration of the Earth Flying Heaven just now. Whether they are readers or not, they can't help but think about it after hearing this question, and then, many people are confused. Why?

Emperor Chongzhen looked at them, and naturally knew in his heart that this apple question was not something they could answer, so he didn't wait for anyone to answer, and he didn't want to wait for anyone to answer, so he continued to say loudly: "This is because there is gravity between any object, which I call gravitational force. This force is directly proportional to the mass of the object and inversely proportional to the distance between the objects. “

As he said this, he slowly glanced at all the people he could see, and when he saw that they were all stunned, he said loudly, "I'm afraid that everyone won't understand what I said. It doesn't matter, the second batch of the "Science and Technology" series will soon be issued to the world. If you take a closer look, you will understand what I am talking about. And the reason why I mention this here is to tell you that if people want to fly to the sky, they must overcome this gravitational pull. This is the same as floating in the water, how much buoyancy does it take to make people float in the air and move forward? ”

"Know what it is, know why it is!" Emperor Chongzhen's voice echoed near the Qilin Gate, "Kong Ming lanterns, hot air balloons, and also involve the scientific knowledge of air density, to calculate the weight of people, how buoyant it is, how big a hot air balloon should be, etc., everything is knowledge." If you have a deep knowledge of these science and technology, then flying will not just be sitting in a hot air balloon, at the mercy of the wind. Just like the airship that I asked my apprentice to make, he can initially overcome the influence of the wind, and he can fly wherever he wants! Later, you can also make more advanced flying machines, and when the time comes, you can fly on the moon. And the key to all this is in science and technology. “

Speaking of this, Emperor Chongzhen paused, let them digest the words just now, and said loudly again: "It is not a lie that science and technology have changed the world. One day in the future, from Jingshi to Yingtianfu, it will not take an hour to arrive, and one day in the future, our children and grandchildren will be able to go to the moon, and all of this requires us now, work hard to learn science and technology, and change the future! ”

After saying this, he said no more, and ordered to drive back to the palace.
