"Wow, it's scary, it's scary."

"I don't dare to look at it."

"It's so windy."

"There's a river down there!"

The four babies have four moods, and they see different things, but although they cover their eyes, they still show their small eyeballs from time to time and look at the earth on the ground.

If they don't see it clearly, they won't be able to tell everyone when they go back, but if they see it too clearly, they will feel scared and fresh.

Only the second baby seems to be the most courageous of the four children, and I don't know why, it's obviously a girl, but she has more courage than the other brothers.

Fan Jingjing looked at the scenery below but didn't feel much, because the height of the current type was about the same as the height of the place where she lived in the future.

The distance outside is different, but after all, there is no such stability and floating as a general building, which makes people feel a little empty.

However, since the others dared to let her get on the airship, they had basically ensured the safety of the airship, even if there was a temporary accident, they were ready, and the first-aid strategy could reduce the possibility of falling and hurting.

Of course, since it is a first-aid strategy, it is not so safe, but they have also tried it many times.

Actually, it's something like a hang glider.

Although she only reached a higher place, Fan Jingjing had the feeling of real flying.

You can also blow the wind outside, and your hair flutters. Fan Jingjing's heart was flying, she was able to get out of the control of the imperial power, and no one could pull her down, because at this time, the ability of the sky was not something that ordinary people could grasp.

However, Fan Jingjing thought of her next anti-air development of the palace and the anti-air development of the royal family, due to the investment of the whole country, it is estimated that it will be able to make a long progress.

In the future, it may become a major mark of the Tang royal family, and it is estimated that the difficulty of rebelling in the future will be higher.

And with air supremacy, although the speed of walking is not as fast as that of a galloping horse on land, they are not like horses, they need to rest, they need to rotate, and they can walk in a straight line, but horses cannot walk in a straight line.

However, when Fan Jingjing was in the air, he had already begun to tell them a new concept, and the air should pay attention to the big circle line, not a straight line, and the big circle line is actually the shortest distance.

Moreover, there are many air currents in the air, and flying straight and straight are not necessarily the most labor-saving ones recently, they must be able to count the existence of air currents.

For the people of Fan's Manor, fluid mechanics is also a new knowledge.

Although they have all been exposed to air before, and they know that the wind will flow, but they have never known what impact these flows will have on people, and now that they have airships, they know that these flows will definitely have an impact on the airship, so for the safety of the airship, they must learn how to judge these air flows, as for Fan Jingjing's concept of fluid mechanics, in fact, it is only from physics, and more deeply, she is completely unclear.

You must know that although she was a science student in high school, she didn't have much in-depth understanding of physics.

In order to escape physics, she entered the College of Agriculture, but she didn't expect that the College of Agriculture would apply various concepts of physics and chemistry more widely, which made Fan Jingjing's head almost blow up.

Fortunately, although it is agricultural physics, many physics can be applied in agriculture, and the teacher will not pay special attention to their non-professional knowledge, but more to their practical skills.

If these professional knowledge can be used, teachers will teach them how to use some of the skills they can use, learn them well, and as for those who can't use it, just wait for them to use it, and then understand it well.

As far as the teacher said, interest and demand are the best teachers, when you have needs and interests, you will naturally study hard, but unfortunately Fan Jingjing came to Datang, even if she wants to study well, there is no chance.

But there are some science students around her, although they have not been trained in basic physics concepts, but these people are very interested in physics, because they need to use this physics to make the flying tools around them safer and safer.

The flying tools around them are magical, they must achieve their goals, and no matter how hard they study to achieve their goals, they will work hard to learn and learn.

Interest is really the key to enlightening knowledge, because these people will not only learn knowledge, but also be able to draw inferences, and when they draw inferences, if they encounter a situation that they don't understand, they will try to find the direction.

Fan Jingjing couldn't solve it, so they used various experiments to solve it themselves, because Fan Jingjing told them that experiments were the best tool for solutions, so they trusted Fan Jingjing very much to keep doing experiments.

It's just that they have to waste a lot of materials when doing experiments, and the wasted materials are all paid for by Fan Jingjing, and Fan Jingjing takes out this money, so he naturally hopes that they can get better results.

But experiments are like this, although you hope to produce results, but the results are not shown in front of you, and sometimes when the results appear, it is often from your negligence or accident.

Of course, an orderly experiment can still deduce a relatively good project close to the truth, and even get the answer to other things in the process of experimentation.

Because accidents are everywhere, the results of experiments may also be the result of other kinds of experiments rather than accidents.

The results of other experiments, if recorded, can often create a lot of new businesses and new productions, making people's lives more comfortable and comfortable.

Perhaps science and technology are constantly attracting people's input when people's ideas begin to change.

In fact, when a person is doing nothing, or can only live a repetitive life, these new discoveries and new inventions are very attractive to the inventor.

And more importantly, after the invention has a reward, they have a greater sense of achievement, with a sense of achievement, they will do their best when doing things, and what they can do, others may not be able to do, so that they feel that they are beyond ordinary people and can get a greater sense of achievement.

It is also these sense of accomplishment that make them gradually become scientific research dogs, constantly creating inventions, and many people send projects to their hands, they are almost too busy to eat and rest, and the whole person is many years old.

Although there is enough nutrition in the Fan family manor, as a result of the overuse of mental power, the condition of the whole person is not very good, so Fan Jingjing has to adjust the airship this time, so he brought in all the people who worked hard in research.
