The hot air balloon floated farther and farther away, and some people on the ground could no longer see it, so they wanted to chase after it. After all, this was the first person flying in the air, and such a spectacle was worth watching for a while.

However, the soldiers who maintained order on the street did not withdraw. Seeing that someone was about to take action, they warned: "The flying ceremony has not yet ended, and no one is allowed to move."

This move naturally means that you cannot leave through the street or go to the toilet, so it is not the case in this case.

Those who wanted to chase and watch people heard that the flying ceremony was not over yet, which means there was a follow-up, so they had to continue waiting in place. They were a little surprised that the hot air balloon had already floated away, and it was not over yet. Should they float back again?

Waiting was boring, and the people of Yingtianfu on Qilin Sect began to discuss what they had just seen.

"I don't know who wrote it. I can write it or not. I'm embarrassed to take it out in the public courtyard!"

"Does people say it's a couplet? Stupid! There's nothing that can't be done, only unexpected! This sentence is so domineering!"

"It's reasonable. Think about it, a few people dare to think about this flying thing, but now you can see that they can do it! Carpenter Xu is so amazing!"

"Can't it be great? He is the apprentice of the emperor today. Do you say that he has no ability and can become the apprentice of the emperor? With the advice of the emperor, what can't he do?"

"Technology is strong, and technology changes the world! If you talk about it, it seems to be true! Even something like Feitian can do, so what else can't be done?"

"Where are the books on science and technology? I also want to read them, but I may have great inventions!"

“…”

There are almost no exception. Whether it is princes and ministers, or ordinary people, their discussions start from that couplet. It is really the place where this couplet appears too eye-catching and is displayed on the highly anticipated balloon. It is the most appropriate time and place.

If, in the past, under the intentional guidance of some scholars, this scientific and technological knowledge was considered to be the learning of craftsmen and lowly knowledge, after the shock and publicity of this scene just now, especially the finishing touch of the two slogans, this scientific and technological knowledge has suddenly risen to a very high level without realizing it. Think about it, "A country of science and technology is strong, and technology changes the world", then what else can be more powerful than this?

Many people's thoughts at this time were that they wanted to find the science and technology series promoted by the court immediately, read it carefully, and see if they could find anything from it, and they could do such a highly anticipated thing! Everyone believes that such a big thing will be passed down through the ages!

Among them, there are even many female relatives of dignitaries. They basically don’t go out of the gate and don’t go out of the gate. In the past, they were mostly piano, chess, calligraphy and painting. After being locked in the boudoir for a long time, they had seen such new things. Therefore, they were thinking about it and wanted to see what this scientific and technological knowledge was like? So, Madame Curie of the Ming Dynasty already had seeds and was waiting to take root, sprout, blossom and bear fruit in the future.

On the side of Emperor Chongzhen, Xu Zhengming was his apprentice, and he wrote the Science and Technology Series. At this time, he had heard the continuous prompts of achievement values ​​in the system. Among these senior officials around him, some have begun to contribute achievement values.

This can prove that at this time, some of these officials congratulated Emperor Chongzhen and flattered Emperor Chongzhen, which was indeed sincere. In this regard, Emperor Chongzhen paid a little attention to who had contributed and who had not contributed and achieved?

Some people can’t see hot air balloons, but some people can see hot air balloons. People who can see it are always broadcasting the hot air balloons live, and they float there from time to time. So, in their discussion, there are different contents. It’s nothing more than Xu Zhengming who floated by Yingtian Mansion. What would the scene of Yingtian Mansion look like? It should be very beautiful, right? The inner city and the Forbidden City are all very good? Have you seen anything you shouldn’t see? Isn’t it very satisfying?

So, the rich people all have an impulse to go to heaven to see what the scene will look like from heaven to see the underground? These people are not short of money, and have even thought about it. After looking back, they will spend money to make it. Isn’t it just a huge Kongming lantern? Do it a few more times, and you may be able to make it yourself!

Finally, someone rumored that the hot air balloon had floated past Yingtian Mansion and landed outside the city. So someone wanted to leave again and wanted to go and see, but the soldiers on the street were no longer allowed to pass, and the flying ceremony was not over. Everyone had no choice but to wait helplessly. They were also a little curious, not knowing what else to do next?

During this waiting process, they had almost talked about the hot air balloon itself. Now when they were waiting, they were mostly talking about the stories behind the hot air balloon, such as how was Xu Zhengming accepted by the emperor as his apprentice? Where did the emperor learn scientific and technological knowledge? How powerful is this scientific and technological knowledge, etc.

The effect of everyone gathering together to chat is difficult to compare with any other promotional method. This has a great impact on mobilizing everyone's interest. As their discussions finally came from the distance of the street.

A fast horse was racing, or the horse was not running fast, just running. The reason for this was that the knight on the horse should be a novice and was not good at riding. While riding, he shouted loudly: "Master, I did it!"

"Master, the disciple succeeded!"

"Master, my disciple can be a more powerful airship!"

“…”

When everyone heard this shout, he knew that this knight was Xu Zhengming who was in the sky just now. He successfully landed on the ground and was coming back to report the good news!

Hey, wait, he is reporting good news to his master. Isn’t his master the current emperor? Could it be that the emperor is actually in Yingtian Mansion? Otherwise, what’s the point of yelling like this?

Thinking of this, everyone was shocked. Could it be that the emperor who was far away in the capital had really arrived in Yingtian Mansion?

The people of Yingtian Prefecture have always been a pity for the emperor. You must know that after the founding of the Ming Dynasty, the capital was chosen by Yingtian Prefecture! In the past, they were the people of the Ming Dynasty under the feet of the emperor! But since the beginning of Chengzu, they have lost this pride.

At this time, I realized that the emperor might be in Yingtian Prefecture. All the people stretched their necks one by one, and even looked at each other where the emperor would be?

As a result, Xu Zhengming was once again paying attention. Everyone knew 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, some people have guessed it. If the emperor is really there, he should be at the head of the Qilin Gate, right?

However, there were no one wearing emperor's clothes there!

"Master, my disciple's hot air balloon test was successful and I can be an airship!"

"Master, please tell your disciple to make the airship!"

“…”

When approaching Qilin Gate, Xu Zhengming shouted with the eyes of "airship". This made the people of Yingtian Prefecture who heard it immediately pay attention to the airship? What airship?

If hot air balloons are actually very ordinary in their eyes, after all, there is an example of Kongming lantern. Xu Zhengming said that after he succeeded in making the hot air balloon, he could make an airship. Obviously, this airship should be a more powerful flying thing. At this time, in their minds, they could not imagine how this airship was like? Suddenly, the mysterious airship successfully attracted their focus.

While they were thinking about this, they really saw Xu Zhengming riding a horse under Qilin Gate and then dismounted. Then they raised their heads under the city, looked at the top of the city, knelt on the ground, shouted loudly: "Master, under your guidance, I have become the first person to fly in the sky since ancient times! My disciple's wish is realized, and I have no regrets in this life!"

Xu Zhengming's words were really his heartfelt words. Of course, now, this is just his first dream. He has decided in his heart that he should work hard for his second dream, that is, to build an airship.

Almost everyone saw this situation and stared at the top of the city. They thought, looking at this, the emperor really came to Yingtian Mansion! If someone stood up and replied, that person must be the current emperor!

Under the gaze of everyone, Emperor Chongzhen was still wearing plainclothes, approaching the battlements, looking down at Xu Zhengming below, and said loudly: "I am very relieved that you can make a safe hot air balloon as scheduled under my guidance!"

When these people near Qilin Sect saw Emperor Chongzhen appear, they realized that they seemed familiar, and then they remembered it. Isn’t this the young man who walked all the way from front of him with two women!

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

As if to verify their thoughts, they saw the senior officials of the court who followed the emperor from the city kneeling down to greet him: "Long live my emperor, long live my son, long live my son!"

Immediately afterwards, the soldiers above and below the city all faced the emperor's position at the Qilin Gate and knelt on one knee together and greeted each other: "Long live my emperor, long live, long live!"

The emperor is here!

No matter where the people are, they all shout long live.

Some people looked at the emperor on the top of the city and suddenly had an idea in their minds: How great would it be if they could see the emperor frequently, or if the emperor would stay in Yingtian Mansion in the future!

Emperor Chongzhen was used to seeing big scenes. After everyone greeted him, he raised his hand and signaled everyone to flatten him. Then he said loudly: "Today everyone has seen that hot air balloons can take people to fly in the sky, just like the common Kongming lanterns. However, I want to tell you that this large Kongming lantern is not easy to make!"

The demonstration of the hot air balloon is a big event that just happened, and many people also had the idea of ​​doing one by themselves. At this time, they 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 to ask you first, why do people have to walk on the ground instead of floating to the sky? Why do apples on trees fall to the ground instead of falling to the sky? Why..."

When everyone heard what Emperor Chongzhen said, he was stunned. Isn’t this something that everyone knows? Why do you still need to ask? Under normal circumstances, if ordinary people ask such a question, the person who hears a comment from a "psychopath" will not let the question go wild at all.

But at this time, it was different, because this question was asked by the Emperor of Ming Dynasty after the demonstration of Di Feitian. Whether it was a scholar or not, he couldn't help but think about it after hearing this question, and then many people became 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 did not wait for anyone to answer, nor did he want to wait for someone to answer, so he continued to say loudly: "This is because there is gravity between any object, which I call universal gravity. This force is proportional to the mass of the object and inversely proportional to the distance between objects."

When he said this, he slowly glanced at all those who could see. Seeing that they were all stunned, he said loudly: "I'm afraid everyone won't understand what I said. It doesn't matter. The second batch of the "Science and Technology" series will be published in the world soon. You can understand what I said. The reason why I mentioned this here is to tell everyone that people want to fly to the sky is to overcome this gravity. This is the same as floating in the water. How much buoyancy is needed to make people float into the air and move forward?"

"Know it, know why it is!" Emperor Chongzhen's voice echoed near the Qilin Gate. "Kongminglantern, hot air balloon, also involves scientific knowledge of air density. It is necessary to calculate the number of people, the buoyancy, the size of the hot air balloon, etc., everything is knowledge. If you have profound knowledge about these scientific and technological knowledge, then Feitian will never just sit on the hot air balloon and be merciless at the wind. Just like the airship that I asked my disciples to make, they can initially overcome the influence of wind and fly wherever they want! After that, you can also make more advanced aircraft, and then the moon can fly up. And all the keys are in science and technology."

Speaking of this, Emperor Chongzhen paused for a moment, let them digest what they said just now, and said loudly again: "Technology changes the world, no silence. One day in the future, from the capital to Yingtian Prefecture, it takes less than an hour to reach it. One day in the future, our descendants can reach the moon, and all this requires us now, to study technology and change the future!"

After saying this, he stopped talking and issued an order to return to the palace.
