The lady who came back from the robbery turned out to be the proud female sword emperor

Not revival, but rise!

If a down-and-out Duke’s family is only rich, its status in the capital can only be regarded as middle-lower. There are many people who can grab the beard of the Fu family, but now... Amazing man, and this man is extraordinarily young!

It is no longer just a noble name, but a real official position. Although he is not the most prestigious high-ranking official in the capital at present, he started as a third-rank Minister of Economic Affairs!In the future, I might be able to go to the Minister of Jingbu from the second grade!

Everyone is powerful. When you bully a person, you will start to wonder how to ease the relationship with the other person, or even... build a good relationship.

The weather in November was getting cooler, the carriage was speeding along the suburban path, and the wind that came in through the curtains felt like a knife cutting.

However, Li Yunfei had already made preparations. When he went out, he had already put on thick clothes and a mask on his face, which could minimize the damage from the cold wind.

He was the only one who needed such equipment. The three women on the carriage sat next to him, and their dresses were still the same as before, without much change.

It's really convenient to become a warrior...you don't even feel cold.

But that's okay, at least he can appreciate his wife's youthful and beautiful dress at any time~

Let's take a look~ Wushuang leaned on the shoulder, he could clearly see the white collarbone, and he could even see the white calf faintly flowing from the skirt...

"Coming..."

Putting aside the unhealthy thoughts in his mind, Li Yunfei opened the bed curtain at this time, looked at the scenery outside, and after more than an hour of driving, the carriage had already driven to a mountain on the outskirts of the capital.

This area, roughly seven or eight miles in radius, was once the land of a certain family, perhaps it was awarded to a family of Conglong when the Wei Kingdom was founded hundreds of years ago.

It's not a good place, the vicinity is not very flat, so naturally it is not a good cultivated land, so even now, this area has not been used, and the family is just sitting on the title deed.

However, some time ago, this title deed fell into Li Yunfei's hands.

Li Yunfei asked Aunt Fu Ying to help buy some land around the capital, the closer the better, it would be even better if it could be connected to the city, and this is one of the lands that Aunt Fu Ying bought.

The price is very low, because those aristocratic families don't know what the use of this dilapidated land is, and it was just rotten in their hands before, but now, someone wants to take the land, and they don't care whether it is good land or not? !

How can such a good thing be missed?

Therefore, this place became Li Yunfei's experimental place in the future. He would bring here any works that need to be investigated and tested by the outside world. Of course, Li Yunfei also had other ideas.

In fact, you can also consider setting up a place here in the future that is similar to the work of the construction team of the villa. Local research and development, local experiments, very convenient...

...

Get off the carriage, this is the highest point of a nearby hill, and there is probably a drop of more than [-] meters from the flattest area nearby.

This height, neither high nor low, is just right for...

"Get those things out"

Li Yunfei said, and then began to inspect the surrounding terrain, and then began to calculate the weather and wind direction and size of the day.

Bai Wushuang, Fu Shishuang and Kong Yage moved out the large and small bags from the rear compartment of the carriage. Although there were many things, they were not heavy.

"Is this the thing my husband didn't finish trying yesterday..." Bai Wushuang said to himself, and then turned his eyes to Fu Shishuang, "Xiao Shuangshuang, what is the use of this thing you made for my husband?" of?"

"Yunfei said...these are wings that allow people to soar in the sky."

Fu Shishuang replied according to the blueprint in memory, while checking the tiled objects, large and small.

"Eh?"

Bai Wushuang was stunned for a moment, and Kong Xiaoli, who was eating a small fruit, also noticed the large and small parts on the ground. Obviously, both of them were curious by Fu Shishuang's words.

"Flying in the sky?! Husband, is what Xiao Shuangshuang said true!"

illustration correction

Regarding Bai Wushuang's hair color, I said that the setting I gave was white, to be precise, it was pinkish white. The setting submitted at that time was written like this, but the previous picture could not be seen. The reason is now asking It came out: the flames of war are reflected on it, so it has a golden fire color, and some parts can still be seen as silvery white...

It may not be obvious, so some painter friends in the group helped to process a few pictures, thank you Ye Muda~

The following is the changed picture

Chapter 779

Bai Wushuang swallowed, then conveniently turned his head to look at Li Yunfei who was still calculating the terrain and wind force.

"It's not that magical, and it's just a trial, not necessarily a success"

After finishing the calculation, Li Yunfei nodded and responded to his wife's question.

That's right, this time he was going to experiment with another blueprint he gave Fu Shishuang recently. In addition to opening the flintlock, Li Yunfei also imagined what kind of equipment he could make for the people around him.

My biggest problem is output, and now Shu and Xihe are expected to make up for it, but for Bai Wushuang and others, what Li Yunfei can think of for the time being is to increase his mobility...

Hearing Li Yunfei's affirmation, Bai Wushuang immediately raised his small hands.

"Then I want to try! I also want to learn how to fly in the sky like a bird!~"

She looked extraordinarily excited, not only Bai Wushuang, but also Fu Shishuang and Kong Xiaoliu also looked forward to it.

Li Yunfei can understand their desire to fly in the sky. After all, from ancient times to the present, every person may have dreamed of rushing to the nine heavens to embrace the moon.

However, what he made is not really equipment that can make people fly...

Well, by people I mean normal people.

Li Yunfei shook his head. If they really wanted to be warriors from this world, perhaps something like a hang glider could really become their wings in the sky.

Because of the previous experience of being complained about naming, Li Yunfei decided on the naming of the hang glider on the way here this time.

chasing the wind...

Li Yunfei looked at the disassembled parts on the ground. In his eyes, the assembly methods of these parts were quickly traversed once.

For the convenience of portability, the blueprints he designed were intentionally modularized, but the disadvantages are real, and the portability is realized, but the price is that if you want to use it in the future, it will take a lot of time to assemble it.

"Just wait, I'll test this thing after I've assembled it"

After all, Li Yunfei got busy, while Bai Wushuang and the others had been staring at Li Yunfei's movements with great interest. Because of curiosity and excitement, they watched very carefully, as if they wanted to engrave Li Yunfei's every movement. Same in the mind.

It's good to have a look... Anyway, Li Yunfei will have to teach them how to assemble it later, just to deepen their impression.

It took more than ten minutes for Li Yunfei to assemble the wind-chasing hang glider.

Above the ground, the hang glider spans four meters as a whole. Regardless of whether it can fly or not, the workmanship alone looks pleasing to the eye, and it looks very textured.

The overall keel is made of the lightest wood in Wei, but this kind of wood is extraordinarily tough and strong enough. The umbrella cloth covering the beam and keel is made of oil-treated oil. The canvas, of course, is covered with animal skins to make it more airtight.

Just like a sheepskin raft, animal skin is the most natural airtight material, and it is just right here.

The operation and the mast are made of metal, which is used in a very small amount to ensure higher strength to avoid damage. The tension wires on the umbrella wings are made of steel wire, which is the strength that Fu Shishuang has repeatedly punched out with a hammer and Mojia wire drawing equipment. Works with great toughness.

Well... Finally there is the hanging bag, also made of good quality cloth, which allows the person using the wind-seeking paraglider to put his legs in it, so that the legs can focus on the weight, and at the same time it is very comfortable for the user Provides warmth, but the main effect is to make the airflow of the overall paraglider stable and smooth.

artwork...

Li Yunfei caressed the umbrella ribs, this number is undoubtedly a well-made object.

But whether it can fly or not depends on the next attempt.

And this kind of attempt is not something ordinary people can do. After all, this is jumping from the highest point of the hill. If he fails, he will have to reincarnate. Therefore, the only person who can try is a powerful existence like a warrior.

The overall hill presents a trapezoidal slope, even if the drop from the bottom is only a dozen or 20 meters at the moment of jumping out, it is not something he, who has no knowledge of external skills, can do.

And with such a small gap, for a master martial artist like my wife, he can jump up to a height of more than ten or 20 meters by just jumping on the spot, and he is not afraid at all!Moreover, Li Yunfei also had the experience of being hugged down the mountain by Princess Bai Wushuang before.

Usually going down the mountain is to take a carriage and go down the mountain slowly, but being hugged by Wushuang, that is a straight line down the mountain. The inner martial artist can use the inner energy to offset the force of the fall, and the falling speed in the air is very slow, as light as a feather It's like falling down, which is why Li Yunfei chose to let Wushuang and the others take the test.

No matter what happens, nothing will happen, and there will be no loss if you fail.

"Do you understand? If the airflow is unstable and you can't control Chasing Wind, you should immediately get off from above. It doesn't matter if something breaks. I'm most worried about your safety, Wushuang..."

After telling Bai Wushuang a lot of instructions and precautions, Li Yunfei still looked at his silly wife with some headaches.

Is it really okay?In fact, he originally wanted Kong Yage or Fu Shishuang, who are more rigorous, to help with the test, but Wushuang stubbornly wanted to be the first one... Then what can a person like him who dotes on his wife say?

There is no bottom line for spoiling your wife!

"Understood, I understand! Anyway, it's just... feel it with your heart, right?! Okay, husband, don't get in the way, I'm going to heaven!"

God really feels it with his heart!I just said so much...

Li Yunfei's face was shaking wildly, but he couldn't stop Bai Wushuang from rushing out. Facing the blowing wind, Bai Wushuang ran extremely fast, but he also deliberately controlled the speed, because she remembered her husband and her As I said, it can't be too fast, otherwise the current strength of the keel may not be able to withstand the devastation of a master like them.

After running to the edge of the cliff, Li Yunfei held his breath and concentrated, the next moment will be the moment to witness history.

In this world, will man's first flight in the sky be successful?

The mystery is about to be revealed...

"Oh oh oh!!! Husband, Husband, it really flew up! Really! Really!"

In the sky not far away, the wind blew Bai Wushuang's extremely excited voice. The three of Li Yunfei on the top of the hill looked at the hang glider flying up in the sky, and everyone's eyes couldn't help shaking few times.

"Flying up...successful..." Fu Shishuang grabbed the corner of Li Yunfei's clothes. This thing was made by Yunfei's blueprints and her own hands. It was a miracle they created together!

No one has ever been able to fly in the sky, even the Grandmaster... But now, the 'big bird' with its wings spread far in the sky told them.

People can also fly in the sky.

Chapter 780 Air Pressure Difference

There will always be geniuses in the world.

Li Yunfei stared at the figure soaring into the sky with burning eyes, and slowly breathed a sigh of relief. It seems that his wife is really a peerless genius in terms of intuition and movement.

He just explained how to use the hang glider verbally, and Li Yunfei even thought that his wife was not listening at all.

But just relying on her athletic instinct and intuition, she was able to control the hang glider extremely perfectly. At this time, she could even hover in the air, very light and flexible.

"Wushuang, try that!"

Li Yunfei said to Bai Wushuang who had already glided to the far sky, he had imagined many possibilities in his heart, and only after the hang glider could glide successfully, could he continue to explore.

Right after he finished speaking, Li Yunfei saw that the hang glider, whose height was getting lower and lower due to gliding, suddenly accelerated, and then... the height climbed!It's like a real big living bird, fluttering and spreading its wings, rushing to the sky!

Totally doable!

Li Yunfei clenched his fists tightly, and Kong Xiaoliu and Fu Shishuang beside him were also staring blankly at this scene, unexpectedly, as Yunfei said, they could fly freely...

"Once a hang glider is powered...it's not a hang glider anymore..."

Those are the wings that can really allow people to soar in the sky!

For a moment, Yuan Kong's climbing figure was even a little golden under the sunlight, as if an angel had landed in the mortal world.

At this time, Bai Wushuang also changed direction, obviously it was his first time flying but he flew towards the previous mountain very skillfully.

Slow down and land in one go, it's like a movement that has been tempered thousands of times.

"Husband, Husband! He was really flying just now! He was really flying! It's amazing!"

After landing, Bai Wushuang was still holding on to the hang glider tightly. Her hair was a little messed up by the previous gliding, but it still did not lose its beauty.

As a grandmaster, although she can use her internal energy to easily jump tens of meters in height, that is not flying at all, and now the miraculous hang glider created by her husband can actually make them fly!

She couldn't suppress the surprise in her heart at all!

"So why is this, my husband? Why can this little thing fly?"

"Maybe... because of the difference in air pressure?"

Fu Shishuang said thoughtfully on the side, she didn't understand the reason before, but the hang glider was made by her hands after all, and during this time, Yunfei wrote some "New Editions of Physics" for herself, she happened to learned this part of the knowledge.

"That's right, Xiao Shuangshuang is right. It is indeed due to the difference in air pressure. The skin of the chasing glider has a curvature, which is to control the flow rate of the air flowing here..."

Li Yunfei was pleasantly surprised by Fu Shishuang's keenness. Among so many disciples, Xiao Shuangshuang might be the smartest one, and he felt that he could grasp the key points very quickly.

The principle of hang gliding is actually Bernoulli's principle. When the flow velocity of the fluid is faster, the pressure will be smaller, and the upper skin with the curvature will pass more airflow paths at the same time, and the natural flow velocity will be faster, and the pressure will be lower than The lower skin is small.

The pressure below is higher than above, so naturally there is a pressure difference. This is one of the principles that allow hang glider to soar in the air.

That's right, it's just one of them. After all, soaring is not the same as gliding. Gliding will always fall to the ground. When the wind speed on the face is not enough, hang gliding is just a kind of equipment that stays in the air for a short time.
