Jiang Xia shook his head and didn't explain, he returned things like buoyancy to the teacher, and it was difficult to explain to Ying Yinyan.

Anyway, there are disciples of the Mo family, and when the time comes, let them experiment slowly, and they will naturally succeed.

Fortunately, he has encountered this situation countless times, and he is already familiar with it, "Everyone can go to the sky, why can't steel float on the water?" ”

When one problem cannot be explained, just ask another question.

Ying Yin Yan really attracted all her attention by the new question, "So, people can really fly?!" ”

"Hmm." Jiang Xia nodded affirmatively.

Not to mention him, there may not be one in hundreds of millions of people who can build an airplane.

Building an airplane is something that no one person can do.

But......

If you want to fly, there is not only one way to fly.

Ying Yin Yan excitedly pulled Jiang Xia's sleeve, "Sir! At the current level, can you fly? Sir, can you take me to the skies to see? ”

Jiang Xia coughed lightly and pulled out his arm without a trace.

Yingyin Yan, this girl, is not very old, but she is very soft......

Hiss.

Brother Zheng doesn't talk about martial arts!

How many people can bear such a beauty plan?

"Ahem." Jiang Xia hid his embarrassment, "Actually, it's not difficult to rise into the air at the current level, but it is estimated that it can't rise too high." ”

"Really?!" Ying Yin Yan grabbed Jiang Xia's arm excitedly, and couldn't help but scream.

Take to the skies!

This has been the dream of mankind since ancient times!

Yingyin Yan was of course no exception, and when she heard Jiang Xia's affirmative answer, she immediately pulled Jiang Xia and walked out, "Sir, hurry!" What are you waiting for? No matter how high we can rise, we're about to become the first person ever to take off, so let's go back and give it a try! ”

Xiang Lian, who was in the distance, heard the movement here, and then looked at Ying Yinyan's excited expression, and sensitively sensed that something big seemed to be happening!

In the past, once the people around Mr. showed such expressions, it was usually Mr. who came up with some brilliant idea!

can make the princess so excited, does the gentleman have any new ideas?

Xiang Lian quickly arranged a couple of sentences with his subordinates, got up and chased after him.

On the way back, Jiang Xia probably introduced to Ying Yinyan, "With the current level of science and technology, it is very difficult to fly, and there are probably only two ways. ”

"Two?!" Ying Yin Yan gasped.

How much effort people have made to fly to the sky!

None of them succeeded!

And as soon as the gentleman opened his mouth, it was two?

Moreover, listening to Mr., because of the current level of science and technology, only two can be made!

If the level of science and technology continues to develop, won't there be more ways to fly to the sky?

Xiang Li'an, who was following behind Jiang Xia, trembled with excitement!

He once looked through the classics left by his father, which recorded that Mozi once made a wooden kite, which was made in three years, and then failed in one day.

The failure of the flying kite has always made countless Mo disciples regret.

Fly successfully!

However, because he could not control the direction and angle of the flight, he could only let the flying kite crash after a day of flying.

Since that flight failed, the Mo family has given up the study of flying kites, there is no way, after flying, it is completely uncontrollable, and a person will die if it flies once, and everyone has no way to improve, what else can be done? It can only be put on hold for the time being.

Now, Mr. actually said that he has two ways to fly?!

"Sir! I don't know what the flying method Mr. said? Will it be dangerous? ”

"Asalian." Jiang Xia laughed twice when he saw Xiang Li'an, "I remember if your Mo family ever made a flying wooden kite that resembles the wings of a bird?" ”

"Yes!" Xiang Li'an's expression couldn't help but get excited, "Could it be that the method of flying to the sky that Mr. said is similar to that of a wooden kite?" ”

Jiang Xia said "um", "It's not bad!" In fact, your Mo family can be regarded as creating a precedent for flying to the sky, although it failed, it is enough to go down in history. ”

Erian clenched his fists excitedly.

Flying first!

Gone down in history!

"If you want to say Feitian, in fact, the Mo family's wooden kite has already touched the doorway, in addition to being uncontrollable, there is also a problem is the lack of energy, as long as these two problems are solved, Feitian is not a difficult thing."

It's not difficult!

Xiang Li'an's face turned red with excitement, the big problem in the eyes of countless people is not a problem at all in the eyes of Mr.!

"Ask Mr. for advice!"

Jiang Xia patted Xiang Li'an's shoulder, "Don't worry, when your father and senior brother arrive, it's not too late to discuss it together." ”

Airplanes are not something that can be built by one person.

"In fact, when it comes to flying, what we can refer to is birds that can soar in the sky! The direction of the Mo family is not wrong. ”

Xiang Lian nodded in agreement, their Mo family's wooden kite also imitated birds to make wings at the beginning, but unfortunately it ended in failure.

Could it be that there is something that is not imitated properly?

"If you look closely at the wings of different birds, some birds are short and fat and have small wings, and some have slender wings, and different wings cause different birds to fly in different postures."

"Some can fly with their wings, some need to run, and some need to take off from a high place."

"It's all about the curvature of their wings and their weight."

"I don't know if you've looked closely other than the wings." Jiang Xia patted Xiang Lian's chest, "Most birds have well-developed pectoral muscles, and this is the place to drive the wings of birds to fly, so you must be strong." ”

"The wooden kite that failed in the Mo family, although it imitated the shape of a bird and made wings, did not learn the essence of birds."

"The curvature of the wings causes the direction of movement of the air when it hits the air."

"The most important thing is motivation!"

"How much power is needed and how big can an object take off?" After takeoff, how much power do you need to control the wings to flap to change the direction of travel? ”

Jiang Xia asked a few questions in a row, and Xiang Lian couldn't help but be stunned.

He had seen drawings of wooden kites, which were indeed very similar to birds.

But what about the curvature of the wings? No.

Motivation issues? Well...... Wind? Does it count?

Control the direction? Belch......

So, that's why they failed?

Xiang Li'an immediately bowed deeply to Jiang Xia, he knew that as long as he followed Mr., he would definitely be able to receive a steady stream of guidance from Mr.!

The harvest is huge!

"So what Mr. said, how to solve the problems of equipment that can ascend to heaven now, wing curvature and power? What kind of bird is it modeled on? ”

Jiang Xia spread his hands, "I didn't imitate birds to make liftoff equipment." ”

"Huh?" Xiang Lian was stunned for a moment, and the whole person was stupid, "Is there any other way to lift off than imitating birds?" ”
