Today's Chang'an is empty.

The reason is that dozens of huge airships rose from the outskirts of Chang'an. After they broke away from the constraints of the ground, they floated high to the distance. It seemed to be slow, but it was much faster than the carriage and horse.

An airship was like a hill. These seventy or eighty airships looked like continuous dark clouds, and flew into the distance with the rumbling sound.

At the same time, each airship carries various equipment and technicians. After all, this thing is not something that any soldier on the front line can play with. They even carry a complete set of equipment prepared by spare helium. Fortunately, there are enough airships, otherwise it would take a lot of effort to transport so many things.

Song Beiyun also attended the airship enrollment ceremony today, because it was not only a simple airship enrollment, but also marked the official establishment of the Air Force.

This marks a great step forward in the era. From today on, the name of the three armies has officially changed from the front, central and rear armies to the army, air force, and navy.

If there is no accident, the rank of marshal will be awarded after this war. Because the configuration of the three armies is completely different, the configuration of generals and marshals at all levels will also change.

"Two time travelers are really terrifying."

After Song Beiyun delivered a speech on the rostrum, he came down to whisper to Miaoyan: "This is pulling the limit of the world line to the First World War."

"It's normal." Miaoyan held the telescope and watched his hard work gradually disappear into the sky: "It is natural for one person to stabilize politics, develop people's livelihood competition, and the other person to do technology.

"But there are not many technologies that we can jump at, right?"

"Well, I discovered from the time of the high-power internal combustion engine that there are very few technologies left to jump, and the ones that come later need to take their time. But it doesn't matter. Basically... our task has been completed, at most twenty years, and we will basically be unable to give anyone any help in the next twenty years."

"That's a good thing." Song Beiyun walked over and held Miaoyan's hand: "At least we've done what we should do."

"It's so disgusting." Miaoyan pulled his hand back: "I'm forty years old, don't be so tired."

"Why are you so unromantic?"

"I am an engineer with a wrench, not a beautiful girl in a brothel. I am just a little better-looking. In essence, I am not romantic at all."

“That’s right.”

Song Beiyun sat there, gently touching the stubble on his face. The two of them didn't say the first half again. It was only about twenty minutes later that Miaoyan suddenly spoke: "Where has the telephone pole been laid?"

"It's almost time to reach Kashgar, and it's almost time to pass Kashgar." Song Beiyun replied lightly: "When there is a telegram, there will be phone calls. If there is a phone call, there will be text messages. If there is a text message, there will be a BB machine."

"The order is a bit of a problem, but it doesn't matter, we may not see it."

"Um."

"Um."

After another silence, Miaoyan suddenly leaned his head on Song Beiyun's shoulder: "Let's have a baby."

"Age-aged mothers are very dangerous."

"That's right, then forget it."

"Um."

"Um."

Before he knew it, he had reached old age. Song Beiyun looked at the blue sky outside and seemed to see the time from more than 20 years ago. At that time, everyone seemed to have bright eyes and white teeth, but now they seem to be covered with a layer of gray filter.

Is age unforgiving? I am forty and occasionally I start to recall the past at night.

He still remembers that he and Brother Yusheng were sitting on the ox cart to attend the poetry and prose ceremony of His Royal Highness.

I also remember the shock when I saw hydrogen, helium, lithium, beryllium, boron and odd and even changes.

Before we knew it, time has come to this day, and life has passed halfway, some people have gone, some people will never see each other again, and some people have completely disappeared without even saying goodbye.

Although there is no confusion of youth, it is replaced by a sense of powerlessness that comes with middle age.

Song Beiyun could clearly feel that his pace slowed down, no longer had the endurance of sleepless days and nights for something, nor did he have the longing and melancholy for the wind, flowers, snow and moon.

I want to buy osmanthus and carry wine together, but it is not the same as a young man traveling.

"Have you heard that, Luzhou has erected a monument for you."

"Well, I asked someone to tear it down." Song Beiyun laughed: "I'm not worthy."

"Hahahahaha..." Miaoyan laughed and hiccupped: "What are you going to do if you die in the future?"

"I hope to bury the ashes in any university campus, and put a tombstone on it, and use the periodic table of the epitaphs."

"That's it?"

"What else? Add a QR code?" Song Beiyun chuckled and said, "I don't care about what happened after death."

"It's so free and easy."

"Um."

"Um……"

After chatting for a long time, Song Beiyun got up and followed Miaoyan to the R&D center in Chang'an.

Because the key project at this stage is the development of internal combustion engines, several major R&D centers are working hard on this project.

The engine is definitely a long-term project. There are no high-power engines that can drive tanks in all workshops, and there are no aircraft engines that can allow aircraft to enter the sky.

It would be nice if he could have a propeller plane, then he wouldn't have gotten an airship, but now... use the airship first.

However, there is not no good news. The high-powered military engine cannot be produced for the time being, but there are many extended products. Now in the tank design factory, cars of various shapes are placed there, and even directly skipped the steam-powered car stage to start the automobile testing of the internal combustion engine stage.

Anyway, it is certain now that the car manufacturers must be converted into an arsenal. This is not groundless.

Not only in the engine field, but also more exaggeratedly, there is a plan that is still on paper, that is, the mobile airport plan.

The theory is to produce a huge land fortress, which can provide aircraft take-off and landing, and it has various levels of firepower. In addition to various types of support and supplies around it, a fortress fortress is an entire army.

This plan is exciting to think about. Although it is not likely to be realized, boldness and madness are an indispensable stage for human progress. The reason why land fortresses cannot be realized is actually very simple, that is, this kind of thing does not take into account the interference of the terrain at all.

Its design weight can reach 150,000 tons and 150,000 tons onshore fortresses. There is almost no ground in the world that can withstand such weight crushing. In addition, rivers, lakes, mountains and rivers, huge volumes and exaggerated weight all limit its development.

It is impossible on the ground, but it is still possible on the sea. Isn’t this an aircraft carrier?

Although the theory is here and cannot even be verified, in the engineering world, it is normal for theory to exceed actual conditions for two hundred years. In the original world, the magnetic levitation theory was proposed in 1842, but almost two hundred years later, the true magnetic levitation has not been widely used in major fields.

So the development of science and technology is fast and some are very slow, but the development of theory must be very fast, because theoretical theories are some qualities that the world itself possesses, and they lie quietly waiting for humans to open the door to the treasure house.

But after many theories are obtained, how to crack, apply, design, and use them takes hundreds of years, or even hundreds of years to explore.

The things that Song Beiyun could see in this life were the planes. He also knew in his heart that as for mobile phones and computers, he would definitely not see them, because the shooting accuracy could not meet the standards, and the shortcomings of the basic engineering were there. Not to mention one or two time travelers, even the king of heaven would not be able to come.

This is also a blessing for Song Beiyun and Miaoyan who both studied science and engineering. They have to change to two liberal arts people. They are either internally flirting or palace fighting. The Song version of Yi Xiaochuan and Martai Ruoxi.

Of course, this is also a blessing for this world to be a low-martial world, otherwise it would be like Liu Yang next door, smart people have gone to cultivate immortals, and geniuses have come to be scientists.

Today, in addition to the formal establishment of the Air Force, there is another thing that is considered a big deal, that is, the first step in history has officially begun to be screened.

The content tells the sad and beautiful love story of Liang Shanbo and Zhu Yingtai during the Eastern Jin Dynasty.

This story is actually well-known. Whether it is a storyteller, a theater brothel, or even the word-of-mouth of the elderly, it makes it seem less special.

But this is the first time it was shown in the form of a movie, which is so surprising. What's more important is that with the support of Miaoyan's technology, although the movie is black and white, the frame rate has increased to twenty-four frames per second and has the same dubbing.

This makes this three-hour movie a milestone, because the film's immersion and indulgence are beyond the reach of any other artistic expression.

Almost all the first people who went to the cinema to watch this movie were crying and their voices came out, especially when Zhu Yingtai died of love and turned into a butterfly. When the classic song "Book of Liang" came out, the audience cried bitterly.

However, this movie was not praised by Song Beiyun because he did not like this shabby story. Why should Ma Wencai be scolded as a disaster by the times? The initial sample did not mention what kind of person Ma Wencai was, but in the subsequent legend, he was scolded for hundreds of years, just because he was not dead? So he did not like this kind of subject matter, especially this kind of thing, which easily caused people to look at history aside from the historical view, and put aside the facts and not mention who is weak and who is right.

In fact, what he is more looking forward to is a satirical movie like "Modern Times", because only by continuous encouragement and motivation can society develop in a better direction. This thing is unquestionable. If any society wants to move forward, doubts and answers to doubts are inevitable, and satire and responses to satire are indispensable.

Any party will pay a heavy price when it is silent.

Song Beiyun knew that he could not live forever, and he didn't know or be sure what would happen to his descendants. Of course, he hoped to get better and better, but risks would eventually exist, so he advocated getting as many vaccinations as possible and making more constructive opinions.

Those who love love, damn it, go to die.

Of course, love is also one of the eternal themes of human beings. He knows that he cannot interfere, but don’t have too many. Men and women are in love brains, and they will easily be corrupted by capital.

"Respecting ancient times is definitely a disease and needs to be cured. Young people should be encouraged to fantasize about the future, boldly imagine the direction of civilization, technology, and humanity, and make full assumptions about society, politics and religion."

Song Beiyun said this, and this sentence has also been written into textbooks in the field of culture.

At this moment, the expeditionary force had arrived at the east coast of the Turkish Strait and began a confrontation.

This confrontation must have lasted for a long time, because without the advantage of firepower, forcing a crossing of the strait may be the beginning of a failure.

According to the top-secret combat plan of the Blue Commander Zuo Rou, the coalition forces now want to curb the enemy's actions from two directions, so that they cannot cross the mountains and straits, waiting for the arrival of their own super weapons, and exchange firepower for deep space rather than using primitive charge tactics to consume limited vitality.

The combat program of this tactic is to exchange firepower for space. Now that the firepower is insufficient, the space will naturally be insufficient.

If there is no accident, including the mid-way supply and maintenance time of the airship, it will probably arrive at the front line in about three months. That is to say, at the latest, it can launch an unprecedented dimensional reduction attack on Constantinople, the most important city in the west of the Turkish Strait.

Perhaps the other party had never thought that the Asian coalition not only had artillery, but also had air force. Their idea might be very simple, just confronting each other across the sea, because in this era, it would be normal for two armies to confront each other for ten years. There are rarely templates on the battlefield in the future that end a war, from a few years to a few months or even days or dozens of days.

It can now be observed that the European army has also arranged a large number of troops on the front line and has a large number of heavy weapons for defense.

These are all within General Zuo's predictions. Even Yang Wenguang had to praise General Zuo, the military god. What did General Zuo say... Although he didn't know much about his mind, once he was put on the sand table, she would be the eternal god. Yang Wenguang had many fallen into the hands of this sister-in-law.

Now that the confrontation has begun, both sides are still calm, and the front line has been relatively stable. They have begun to use existing resources to expand farmland and production bases. After all, in the confrontation, there is still a lot of free time outside of daily training.

Gou Dan sat by the beach and looked into the distance. He could clearly see that the high ground opposite was covered with artillery formations, which means that the other party was also waiting for them to fight across the sea.

"Brother Goudan, what are you going to do tomorrow's rest?"
