In Luguo, Qufu, and in a vacant space on the outskirts of the country, countless pedestrians were looking curiously at the glider jointly built by Gong Yi and Gu Xiaobai.

The length of the glider is about two meters, and the shell is hollowed out from a single intact cedar tree.

The exterior is polished with river stone without a single burr, showing a beautiful streamlined shape.

A pair of slender wings, on the other hand, are nearly ten meters long and stretch out to the sides.

This pair of wings is also made of cedar wood, which is an eclectic material of density and toughness that Gu Xiaobai and Gong Yi can find.

Glider, the tail ends of the wings are bent and bent upwards into an almost right-angled arc.

However, in order to reduce weight and maintain the center of gravity, the glider does not sit in the cockpit in the upper part.

Its upper half is closed, and the lower half is hollowed out, creating a groove that can accommodate a person, and through some straps, a person can be fixed in the groove, and then by pulling the rope, the tail of the glider can be manipulated to control the direction of the glider's flight.

The whole glider is so light that one person can carry it.

Add to that a simple mechanism to maneuver the tail of the glider, and that's all there is to this glider.

After all, due to the limited materials, the glider is not large, so it can only be as lightweight as possible.

In order to allow himself to fly, Gu Xiaobai starved himself for a few days recently to lose weight.

The onlookers were very unoptimistic about this thing.

"This is a woodbird that can take people to the sky?"

"This thing can fly? It's not like a bird......

"No matter how you look at it, it can't even fly! Its wings can't even flutter!"

"Like a dead bird...... I think it's still reliable on Mo Zhai's side. ”

"Mo Zhai, that doesn't look like a bird...... It's just a tile, but he can fly. ”

"Come on, come on, open the market, open the market, in the end, can this bird fly, the odds are 1:5, bet on Mo Zhai to win on the left, bet on the right to lose like a public loss, and those who want to make a fortune are coming!"

Today's Qufu is lively like a festival.

In this era, people don't have any entertainment activities, Mo Zhai and Gong loses like a competition, but it is a big show, not to mention that nine out of ten people in Qufu City are paying attention to it, and there are many people who come from neighboring countries to see the excitement.

It's hard to travel all the way for many days just to see the excitement, which is also amazing.

But after seeing the "wooden bird" that can carry people like a public loss, everyone was immediately disappointed.

It's completely different from the colorful and lifelike birds in your imagination.

Do you at least put a few feathers on it to decorate it?

How can you fly without feathers?

Not to mention that the onlookers were puzzled, even the public lost and didn't trust Gu Xiaobai much.

"This thing, can it really fly, and how can it fly without any mechanism, at least put that pedal on it, and I'll say I want to make the wings flutter......"

People in this era have no concept of flying, they think that there is only one way to fly, and that is to flap their wings.

It's a pity that even modern technology can't make a working ornithopter, let alone ancient times.

Besides, where do you need power to fly!

Gu Xiaobai explained Bernoulli's law to the public loss several times, but he didn't see it with his own eyes, and the public still didn't believe it.

But although he didn't believe it very much in his heart, he still stood up, raised his chest and belly, and said like a bell: "Thank you for coming to see the Phoenix Divine Bird made by my public loser!"

"I know you don't believe that this divine bird can fly, so today I will let my grandson show you how this divine bird soared into the sky!"

Gu Xiaobai rolled his eyes beside him, and returned to the phoenix divine bird, old man, you don't build a plane, but you have a set of names.

He was about to step forward, but Bai Hang stretched out his hand and grabbed him, saying, "Childe...... Are you really going? Why don't you let me replace Childe......"

Bai Hang was extremely worried: "If you fall from the sky, what should you do?"

"Don't worry. Gu Xiaobai stretched out his hand and patted Bai Hang's hand: "If I fall, I will be a good man again in eighteen years." ”

Bai Hang: "......"

Childe, this joke is not funny!

Our Bai family has been waiting for you for almost 200 years to wait for your reincarnation, okay, where is this eighteen years? This is obviously one hundred and eighty years!

One hundred and eighty years later, we don't even know if the Bai family is still there!

But how can Bai Hang stop Gu Xiaobai?

He saw Gu Xiaobai walk under the glider and tie himself to the glider with a lacing.

Next to it, the public is still there to sacrifice wine to the heavens and the earth, and there are words in his mouth, saying "The phoenix god bird takes my grandson to the wind, soars the world, and goes straight to the green dome ......"

Gu Xiaobai always felt that this old man was cursing himself and letting himself ascend to heaven quickly.

Gu Xiaobai bent down and carefully carried the glider, not letting his wings touch anything.

After all, the wings are just made of wood, and they are too easy to break.

In this era, except for Gu Xiaobai, no one may be able to control this helicopter, because he must carefully choose the air flow in the air, as long as the wind is a little stronger, it will be the end of the wings and death.

Then Gu Xiaobai got on a flatbed truck and attached the towrope to the glider.

Eight well-trained horses galloped forward with a flatbed cart, the road was a little uneven, and Gu Xiaobai's legs were slightly bent down, acting as a cushion for the human body.

As the horses got faster and faster, he also felt the glider on his back and began to have a strong lift.

It was very windy today, and eight horses pulled the carriage and ran wildly against the wind.

When the combined speed of the wind and the speed of the horses exceeded 40 kilometers per hour, Gu Xiaobai only felt that his body was light, and his feet had vaguely left the flat car underground.

Gu Xiaobai squinted his eyes and listened attentively, in front of him, there was another strong wind blowing, and before the wind came, Gu Xiaobai had already heard the wind noise.

His hands suddenly let go, and he shouted, "Get up!"

With a "whoosh", the glider suddenly lifted upward, and then shook slightly, as if stepping on invisible steps, climbing up step by step.

Gu Xiaobai heard countless exclamations from below.

"It's flying!"

"You can really fly!"

"Oh my God, that's really a divine bird!"

But that's where it goes!

Getting off the ground is the most difficult step for gliding.

Next, it's time for the birds to fly!

Gu Xiaobai manipulated the glider to fly against the wind for dozens of meters, and felt that the kinetic energy was a little insufficient, so he manipulated the lever to turn around in the air, and drew an arc to start accelerating along the wind direction.

He swept diagonally across the treetops and flew towards the mansion of the loser, speeding up and rising with the help of the updraft generated by the roof of the mansion.

Then turn again, face the headwind, and continue to rise!

Potential energy and kinetic energy, just like this, are constantly converting, accumulating, Gu Xiaobai hovers back and forth in the sky, flying higher and higher, flying faster and faster.

His excited shouts echoed in the heavens and the earth: "Whoa, whoa......"

I'm flying!

Is flying in a helicopter?

This is the real flying!
