This is not the first time Gu Xiaobai has flown up.

He once rode a towing umbrella hanging behind the Dragon Palace on the sea, felt the wind flowing by his side, and even manipulated the Dragon Palace on the sea to control the air flow and let himself fly at different altitudes.

He also used to fly in a helicopter between the Dragon Palace on the Sea and Dongyuan University, soaring over the city with the power of modern technology.

But he had never felt that way.

Freely!

One with heaven and earth!

What kind of flight is the purest in the world?

Unless one day humans can evolve wings, or have anti-gravity abilities like the superpowers on TV.

Otherwise, using a glider, it may be the closest way to fly in nature.

In aviation, there is a joke.

As long as the power is sufficient, even a brick can fly into the sky.

Illustrate the importance of power in the aviation industry.

But the glider is the exact opposite of what the modern aviation industry needs.

It doesn't need power except when it takes off!

As soon as you leave the ground, gravity's restraint on you is magically counteracted by a pair of wings.

With your knowledge, your brain, your senses, your skills, you can soar in the sky!

Gliders possess two ways of flying.

One way is called "gliding", through the wings, the gravity is broken down into forward power and falling force, usually paper airplanes fly in this way, generally reduce the altitude, while converting potential energy into kinetic energy, and fall to the ground to end gliding.

The other way, called "soaring", is to achieve level flight or ascent with the help of updrafts.

Finding the updraft is the focus of gliding, otherwise the gliding time and distance of human beings will not be too long, and the glider is at most a parachute that can fly.

So, how high and how far can an unpowered flight fly?

In the common sense of modern people, all flights need to consume a lot of energy, and airplanes are large fuel consumers.

Well, you can't fly too far.

But in fact, modern gliders, which can rise to an altitude of up to 23,000 meters, can fly more than a thousand kilometers at will!

Of course, modern gliders have instruments such as airspeedometers, altimeters, speedometers, sideslip gauges and magnetic compasses to help operators figure out their current flight status and find the right airflow.

But in this era, it is naturally impossible to have these meters.

But does Gu Xiaobai need those? No, no!

He himself is the most powerful meter!

Since experiencing the stormy night, Gu Xiaobai has learned how to use the sound waves in the air to detect changes in air flow.

At this moment, in front of Gu Xiaobai's eyes, the atmosphere is not transparent, but as if it is marked with countless arrows, which are divided into countless colors. The red one is the updraft, the blue one is the descending cold airflow, and Gu Xiaobai jumps and slides between the airflow and the airflow, as if he is surfing.

With the not-so-powerful updrafts generated by some high-rise buildings in Qufu City, Gu Xiaobai flew like a dolphin.

Dive accelerates, rises to maintain altitude, and continues to dive accelerate.

He circled around Qufu City, and his shouts could be heard throughout Qufu City.

"Aha, I'm flying!"

"Woo woo

Two goshawks flew in from afar, looking vigilantly at the behemoth that had suddenly intruded into their territory, their faces full of confusion.

"Aha, hello!" Gu Xiaobai caught a glimpse of a goshawk hovering beside him, and laughed.

Hearing Gu Xiaobai's voice, the goshawk was startled, flapped its wings, and flew aside.

After a while, it leaned over again.

The two goshawks circled around Gu Xiaobai and flew together for a while.

Suddenly, a goshawk didn't know what it saw, let out a "chirp" sound, and flew off into the distance.

After a while, he caught something and flew back to the distant mountains.

Gu Xiaobai listened to its chirping, and also let out an eagle's cry.

It is vivid, but it is longer and louder than the ordinary eagle's cry.

Qufu is surrounded by mountains on three sides, water on one side, and high in the air, Gu Xiaobai's cry spread far away, and even the mountains and rivers in the distance echoed.

Gu Xiaobai swept over the high platform, the city wall, and the farmland in the sky.

In the farmland, the people who were working on the farm raised their heads and looked at the huge gliders that swept in the sky, and they were immediately shocked.

Many people fell to the ground and knelt down.

The brave people are still hiding under the trees and under the eaves and pointing at the side.

"What's that?"

"Such a big bird, it's a divine bird, isn't it?

"How can a phoenix look like this? The phoenix is colorful, I have seen it with my own eyes! I still have a phoenix feather hidden in my house...... You see it, it's bare, except for a pair of wings, where it looks like a bird, more like a fish. ”

"The word of the fish...... Isn't this the Dapeng Bird?

"It must be, this must be the Divine Bird Dapeng, this is a good omen, our Lu country is going to be developed!"

Although these people pointed and pointed, they all whispered, for fear that the Dapeng bird would swoop down from the sky and take them away.

Someone had sharp eyes and said, "How can I see that there are people under the Dapeng Bird?"

"It must have offended the Dapeng Bird and was captured by the Dapeng Bird!"

"This brother is so miserable, come, we also say goodbye, lest the Dapeng bird take us away. ”

"Dapeng Bird blesses our Lu country with good weather and abundant harvest this year, and I also hope that Dapeng Bird will bless and let Cuihua's husband next door ......die soon."

"Wouldn't it be better to let the Dapeng Bird capture him?"

"Yes, you're so smart, Dapeng Bird, Dapeng Bird, hurry up and take Cuihua's husband next door, I can ...... Hey, hey, hey, hey, hey......"

In the sky, Gu Xiaobai swept over the fields, soared back and forth for a moment with the help of a dirt slope, and raised some heights.

Then he got a little impatient.

What's the point of always flying at such low altitudes?

Now that we've taken off, of course it's time to challenge the high level of difficulty.

As for this glider, can it withstand high-altitude flight, can it continue to rise into the air......

Anyway, eighteen years later, he is a good man again!

Gu Xiaobai manipulated the glider and flew towards the distant mountains.

At the foot of the mountain, an air current blew upwards along the peak, and Gu Xiaobai manipulated the glider, circling all the way around the mountain, higher and higher, higher and higher.

At this moment, the people of the entire Qufu City were looking at Gu Xiaobai in the distance.

They climbed on the rooftops, climbed on the treetops, and looked at the "Dapeng bird" in the distance, around the mountains of the five names, all the way up and up......

100 meters, 300 meters, 500 meters, 1000 meters......

Soared!
