In an open space on the outskirts of Qufu, Lu State, countless pedestrians were looking curiously at the glider jointly built by Gongshu Ban and Gu Xiaobai.

The body length of this glider is about two meters long, and its shell is hollowed out from a complete fir tree.

The exterior is polished with river stones without any burrs, showing a graceful streamlined shape.

And a pair of slender wings, nearly ten meters long, stretched out to both sides.

This pair of wings was also made of fir, a material that was a compromise between density and toughness that Gu Xiaobai and Gong Shuban could find.

The tail ends of the glider's wings were bent upward, forming an almost right-angle arc.

However, in order to reduce weight and maintain the center of gravity, this glider does not have the cockpit at the top, but sits in the cockpit.

Its upper half is closed and the lower half is hollowed out, creating a groove that can accommodate a person. Through some ties, a person can be fixed in the groove, and then the tail control of the glider can be manipulated by pulling the rope.

The direction in which the glider flies.

The entire glider is very light and can be carried by one person.

Coupled with a simple mechanism to control the glider's tail, that's all this glider has to offer.

After all, limited by materials, the glider cannot be made large, so it can only be made as lightweight as possible.

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

The people of Lu who were watching were very unfavorable to this thing.

"Is this the wooden bird that can take people into the sky?"

"Can this thing fly? It doesn't look like a bird..."

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

"It looks like a dead bird... I think Mo Di's side is more reliable."

"Mo Zhai's one doesn't look like a bird...it's just a tile, but his one can fly."

"Come on, come on, the market is open. The market is open. Can this bird fly? The odds are 1:5. If you bet on Mo Zhai to win, bet on the left side. If you bet on the public loss, bet on the right side. Those who want to get rich are coming soon!"

Qufu today is as lively as a festival.

People in this era didn't have many entertainment activities. The competition between Mo Zhai and Gongshu was a big show, and nine out of ten people in Qufu City were paying attention. There were also many people who came from neighboring countries to watch the fun.

It was amazing to travel all the way for many days just to watch the fun.

But after seeing the Gongshu-like "wooden bird" that could carry people into flight, everyone was immediately disappointed.

It's completely different from the colorful and lifelike flying bird I imagined.

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

How can you fly without feathers?

Not to mention the confusion among the onlookers, even Gongshu Ban didn't trust Gu Xiaobai very much.

"Can this thing really fly? How can it fly without any mechanism? At least put on the pedal. I said we should make the wings flap..."

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

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

Besides, where is the power needed for flying?

Gu Xiaobai explained Bernoulli's law to Gongshu Ban several times, but without seeing it with his own eyes, Gongshu Ban still didn't believe it.

But even though he didn't believe it in his heart, Gongshu Ban still stood up, with his chest raised and his belly raised, and his voice was like a bell: "Thank you all for coming to see the phoenix bird made by my father!"

"I know you don't believe that this magical bird can fly. Today, I will let my grandson demonstrate to you how this magical bird soars into the sky!"

Gu Xiaobai rolled his eyes at the side and said, "Phoenix?" Old man, you're not very good at building airplanes, but you're pretty good at naming them all.

When he was about to step forward, Bai Hang stretched out his hand to grab him and said, "Sir... do you really want to go? Why don't you let me take your place..."

Bai Hang was extremely worried: "What would you do if you fell from the sky, sir?"

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

Bai Hang: "..."

Sir, this joke is not funny!

Our Bai family has been waiting for you for almost 200 years before your reincarnation, okay? How can this be eighteen years? This is obviously one hundred and eighty years!

One hundred and eighty years later, we don’t even know if our Bai family is still around!

But how can Bai Hang stop Gu Xiaobai?

He watched Gu Xiaobai walk under the glider and tie himself to the glider with a lace.

Next to it, Gongshu Ban was still placing wine to offer sacrifices to heaven and earth, muttering something like, "The phoenix bird takes my grandson to ride on the wind, soar into the sky and earth, straight up to the blue sky..."

Gu Xiaobai always felt that the old man was cursing him to make him ascend to heaven quickly.

Gu Xiaobai bent down and carefully picked up the glider, not letting his wings hit anything.

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

In this era, probably no one except Gu Xiaobai can control this helicopter, because he must carefully choose the airflow in the air. If the wind is just a little bit stronger, his wings will be broken and everyone will die.

Then Gu Xiaobai stood on a flatbed truck and connected the traction rope to the glider.

Eight well-trained horses pulled the flatbed truck forward and galloped forward. The road was somewhat uneven. Gu Xiaobai's legs were slightly bent to act as human body cushioning.

As the horse's speed became faster and faster, he also felt that the glider on his back began to gain strong lift.

The wind was very strong today, and the carriage pulled by eight horses ran wildly against the wind.

When the combined speed of the wind and the horses exceeded 40 kilometers per hour, Gu Xiaobai felt his body light up and his feet had vaguely left the flatbed truck underground.

Gu Xiaobai narrowed his eyes and listened. Ahead, there was another strong wind blowing hard. Before the strong wind arrived, Gu Xiaobai had already heard the noise of the wind.

His hands suddenly released and he shouted: "Get up!"

With a "wow" sound, the glider suddenly rose upwards, and then vibrated a few times, as if it was climbing up step by step on invisible steps.

Gu Xiaobai heard countless exclamations coming from below.

"It's flying!"

"You can actually fly!"

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

But where does this go!

For gliding, leaving the ground is the most difficult step.

Next, the sky is open for birds to fly!

Gu Xiaobai flew the glider for dozens of meters against the wind. Feeling that the kinetic energy was a bit lacking, he turned around in the air with the lever, drew an arc and started to accelerate in the direction of the wind.

He flew diagonally across the treetops and flew towards Gongshu's mansion, using the updraft generated by the roof of the mansion to accelerate and rise.

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

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

His excited shouts echoed throughout the world: "Ouch, ouch, ouch, ouch, ouch..."

I'm flying!

Is flying in a helicopter called flying?
