This year was the second year after the end of the Chinese War, and all the people were silently licking their wounds and rebuilding with hope.

The republic's official reserve and the retraining of officials under the old system have been done very well, so that there has indeed been no shortage of personnel in the newly occupied areas, all the work has been carried out in an orderly manner, and the living standards of the people in the newly occupied areas have been greatly improved.

Zhang Hongbin naturally became the most popular emperor among the people in all dynasties, just because he really stood in the perspective of the people and worked hard for them. And other emperors can't really do it that well.

That year, a large number of potions were distributed in all districts, and local officials had to be embarrassed when they learned of the usefulness of the potion.

Between heaven and earth, there are so many drugs created by heaven and earth? Seriously, when chemical agents are still in their infancy, this miraculous drug and immortal medicine seem to be directly equated. Of course, this is also because most regions have not done enough to get rid of superstitions.

Under the instructions of the higher level government, local officials naturally brought this medicine to the cities and counties under their jurisdiction to publicize it, and at the same time said that all couples who intend to have children can come and apply for this medicine. Within three months of the drug, more than 300,000 couples said they needed to take it.

It is conceivable that after the pregnancy in October, a large number of people will be born in this world. As Zhang Hongbin expected, these families directly used forty milliliters of medicine, which made the fetuses in the womb basically quintaplets. It's just that most families say they want to take male medicine, which is probably directly related to the traditional Chinese idea of inheritance.

Fortunately, Zhang Hongbin was prepared, and the male medicine that was sent down was only 20% of that of the female and dragon and phoenix fetal medicine, which means that most families have to face the most important choice in life: either go with the flow, or give birth to both boys and girls!

Probably seeing that the recent women have also gone to school and worked to make money, women don't seem to be completely losing money, and the most important thing is that in some areas where women are extremely scarce, there is even a situation where they are willing to be sons-in-law, so the people do not reject having daughters.

In the second month of the pharmacy, Congress again issued a new law encouraging children to take their mother's surname, and families could receive a monetary reward for doing so. It's a pity that in the future, maybe this regulation can still be considered, but in this era, under the effect of deep-rooted old ideas, no three or four generations are afraid that they will not be able to do this. But in any case, it provides a legal basis for the future, and also gives hope to families who have never been able to give birth to boys.

Besides, even nowadays, no one can guarantee that there are no attempts to do so.

However, Zhang Hongbin's eyes no longer pay attention to this side, just because there is a new invention on the side of the Academy of Sciences.

Originally, during this time, he had been paying attention to the production of generators, but he didn't want to be mechanical, but the third group made a flying plane transformed from a glider, with a small engine under the design of double flying wings, using a small gasoline-powered small engine. What makes people speechless is that the engine is not original, but is supplied from a supermarket......

But even so, there is no way to deny the concept of setting up this aircraft, without him, just because this aircraft is almost the same aircraft invented by the Wright brothers.

The similarity in appearance is as high as 90%, and at most there is a slight improvement in some places, which becomes more in line with the aesthetics of the Oriental. And, of course, the small engines that were far more advanced than the Wright Brothers' planes.

Airplanes, yes, that's airplanes!

Zhang Hongbin has always wanted to study it, but it is only now that the prototype has been studied. This is still the concept of the glider, and the prototype that appeared after several failures is conservatively estimated to be able to fly into the sky, but it has not been specifically tested.

In fact, there is no way to do this, because of the orders of the government, the most taboo thing for people in ancient times was to study the sky. In their eyes, the heavens were mysterious and noble, and no one except the people of the Qin Heavenly Prison was qualified to study this thing. Without him, just because the emperor's other title is the Son of Heaven, the son of the sky, can you study other people's fathers and other people's sons?

That's it, they all say, 'The emperor is angry and ambushes the corpse for thousands of miles', and studies other people's Lao Tzu's high-end and atmospheric things, don't be angry that other people's sons are lying in the corpse for thousands of miles!?

Therefore, ordinary people do not study the Heavens, and any content that involves the Heavens is consciously avoided. Zhang Hongbin has also been encouraged again and again in recent years, and the talents of the Academy of Sciences have started this research on cross-era significance.

And the origin of this qiē is a decision that Zhang Hongbin made after he was always wondering why there was no such good thing as airplanes for sale in the supermarket. After all: since your supermarket doesn't supply it, Lao Tzu and I TMD can directly study it ourselves!

"Your Majesty, we have completed the prototype of the aircraft you requested, and after the precious number of failures that have come out of the previous few times, we can conclude that this one can really fly in the sky until the dye runs out. Of course, we can't guarantee how high we can fly, after all, there are no tests yet. "This is the old wood himself leading the class, and only he can let him have the courage to carry out this research.

It's just that his words are actually blaming Zhang Hongbin: We just made a trial product, and we haven't had time to implement it yet, why did your old man come to join in the fun?

"Haha, whether you fly or not, seeing that with everyone's hard work, we have finally completed a new achievement, and I always have to come over to pay attention to it. Seriously, I'm really looking forward to watching it fly and fly steadily in the air! Zhang Hongbin simply snorted, but he did not hide his expectations for the plane.

"Well, anyway, you need to be real, why don't you do it today...... How prepared are our pilots? Old Wood asked his assistant.

"One qiē ready! Even the pilots were equipped with the kind of parachutes that His Majesty had asked for! The assistant wiped his sweat and looked worried.

"Okay, let's try it!" Old Wood didn't know what he was worried about, so he motioned for a start.

The Academy quickly gave way to a runway and pushed the aircraft onto the runway, the mechanics made a final check, the ground crew checked the ground conditions, and the pilots put on their flight suits and walked out with a windshield that covered half of their faces.

She seems to be very young, only about ten years old...... The most important thing is, how do you feel that this girl is very familiar...... Isn't this the eldest princess Zhang Tian?!

Zhang Hongbin immediately shouted in fright: "Tian'er, what are you making a fuss about?!" ”

Immediately, he turned his head to look at the old wood, and the meaning was obvious, that is, to ask why the eldest princess became a pilot.

"This, the minister really doesn't know! How did you become the eldest princess...... Mu Jing, what's going on? The old man immediately looked at his assistant.

"During this time, the eldest princess had a very strong curiosity about the flying machine, so when she had time, she would come to ask for advice on how to fly. Just today, she heard that the latest flying machine had been made and planned to be the pilot herself...... We're just courtiers, and we can't beat the princess! The assistant knelt down.

Just when everyone was talking, the plane moved, and Zhang Tian drove the plane and started running.

"Who's coming, who's going to stop this stupid girl!" Zhang Hongbin was really anxious.

"Your Majesty, now I'm afraid I can't stop it......" Lai Mu smiled bitterly, the engine will speed up rapidly, and ordinary people are afraid that it will be difficult to catch up.

The most important thing is that according to the precautions for take-off of the aircraft, no one is allowed to idle on the way to take off, so as not to have an accident. Therefore, at this moment, there is no one else on the entire runway.

At this time, with the fuselage slowly tilting, the aircraft actually began to slowly leave the ground.

Yes, it flew! With the dream of human flight, with the continuous growth of the republic, it flies!

"Yay, I flew!" Zhang Tian shouted on the plane.

But Zhang Hongbin's heart has been pinching, just thinking about when it is over, go back and beat this girl's ass...... The premise is that she must land safely!

"Fly, fly! The plane we built flew, and look, how smoothly it flew! Haha, we did it! Old Wood was only excited at the moment.

"We did it! Long live the Republic! The assistant immediately shouted sensationally.

Suddenly, the entire Academy of Sciences saw this scene and cheered: "Long live the Republic!" ”

In Chang'an City, all the people who saw the plane flying in the air, after hearing the shouts from the Academy of Sciences in panic, also excitedly shouted under the leadership of some smart people: "Long live the republic!" ”

Yes, this is a truly joyful day, the most historic day for humanity!

Because on this day, humans will fly!!
