Chapter 660 Boiling Again, Come On

Leng Feng foolishly watched as soon as the barrier was opened, a silver-white 'magic weapon' leaped into the sky like lightning, and the whole process was straight without any bend.

But then there was a roar.

Wait, this is wrong, whose magic weapon makes such a loud noise when flying?

Leng Feng just foolishly watched that silver-white figure get into the white clouds, and then pass through the white clouds. Finally, with his golden body cultivation, he could only see a small gray dot disappearing in the sky.

He really wanted to follow it, but seeing the dozen or so masters of the Oceanic Group following that weird flying object, he gave up the idea.

Dayang Group and any spies are truly ruthless. For example, in this base, it is said that the on-the-spot beheading within one kilometer, the result is merciless.

According to Dayang Group, this place is so remote and desolate, approaching without the permission of Dayang Group, what is it if it is not a spy?

Leng Feng has seen it with his own eyes. A master in the late stage of Huashen wanted to spy on information. As a result, three masters of supernatural powers appeared directly from the Dayang Group, and they were killed on the spot without saying a word; not drop.

So even though Leng Feng was extremely curious, he didn't dare to jump out. He believed that as long as he jumped out, he would definitely not be able to leave alive.

Cold Wind could only wait quietly, waiting for that thing to return.

And this wait is half a day until dusk.

…………

But Lin Yinghao has let himself go. Different from flying with self-cultivation methods, flying an airplane is another experience.

The powerful push back made him feel an unprecedented sense of satisfaction. Using the aircraft he personally designed and personally participated in the manufacture to soar into the blue sky, that kind of pride has surpassed the limit that can be expressed in words.

He even opened the cockpit and let the wind blow. Although Lin Yinghao was not very old at this time, he was already a young master in the early Yuanying period. The 800-kilometer wind and the low temperature at high altitude did not affect him much.

Lin Yinghao screamed, pushed the accelerator to the maximum, and the plane roared as it rushed up layer after layer of clouds.

The higher you go to the sky, the thinner the white clouds become, gradually giving you an ethereal feeling.

I don't know how long it took to rush, but Lin Yinghao gradually began to feel that the plane was struggling, and at this time he also gradually felt that the aura around him decreased sharply.

Reaching the edge of the aura layer!

Lin Yinghao was thoughtful and looked at the altimeter, which showed an altitude of 62.7 kilometers.

The Dayang Group has investigated the height of the aura layer in detail. Calculated based on sea level, the approximate average height is 66 kilometers, but the aura layer is not fixed, just like the sea surface, there will be large ups and downs.

Under normal circumstances, its approximate range is about 62 to 68 kilometers. If there is bad weather, such as strong wind and other weather, the fluctuation will be more intense.

After a while, the plane jumped to an altitude of 63.2 kilometers. At this time, the surrounding aura was almost gone, and the heavy gravity began to pull the plane down.

Feeling the heavy gravitational force, Lin Yinghao's expression became serious.

As a scientific researcher of Dayang Group, and also in the field of aircraft, Lin Yinghao has a full understanding of planetary gravity and so on. Even Lin Yinghao has started to study gravity and astrophysics with Zhao Dahe and others, and has achieved considerable results.

So Lin Yinghao knew exactly what to do now.

The plane returned to level flight and began to adapt and run in at this altitude. Of course, Lin Yinghao also wanted to conduct a simple inspection of the aircraft in this state, especially the limit of the aircraft, in preparation for the next sprint.

The plane began to assume various flight attitudes in the sky. Of course, at this time, Lin Yinghao can only say that he can fly a plane at best, and he is still far from being a true elite. There are no such things as awesome stall recovery, coquettish plane positioning, etc.

After testing the plane to the limit for half an hour, Lin Yinghao took a deep breath, and the plane began to climb again. But this time the climbing angle was only 1.8°.

Leaving the aura layer, the heavy gravitational force seems to bind everything to the ground. The engine of the plane began to make a dry roaring sound. The plane climbed extremely hard, with a long black tail trailing behind it, which was incompletely burned fuel.

Propeller aircraft, in the case of ten times the standard gravity, can't perform well.

Fortunately, the dense air provides a relatively objective lift, and the plane is still climbing with difficulty.

On the edge of the aura layer, a dozen or so escort experts from Dayang Group could only wander around below the plane. These people looked shocked at this moment, and opened their mouths wide to look at the plane flying freely at high altitude.

That plane, without the help of spiritual energy, spells, formations, etc., flew above the spiritual energy layer! Before Dayang Group wanted to explore the space above the aura layer, they could only use hydrogen balloons.

But the hydrogen balloon is not free, and must be connected to the ground with the help of a long rope.

Dayang Group also tried to research airships, etc., but in the end they had to end in failure. The air in this world is too thick, the wind is strong, the thrust is strong, and there are practitioners flying all over the sky, the airship is too vulnerable to attack, and even more likely to be robbed.

Three years ago, Dayang Group sold the airship, but soon the airship in the sky was shot down by an inexplicable attack. In the end, commercial airships or hot air balloons just withdrew from the stage.

But the current aircraft seems to be different. No, it is quite different!

Airplanes can fly against the wind!

High in the sky, Lin Yinghao piloted the plane, climbing and climbing again and again! The flight altitude of the aircraft is related to the design, engine technology, external air density and oxygen content-at present, the aircraft still uses internal combustion engine technology, which requires external air (oxygen) input.

It's just that the air compression technology has not been realized yet, and there is no turbocharger or turbofan technology, only self-breathing technology.

However, thanks to the thick air in this world, the plane still flew to a height of 108 kilometers!

The altitude is 108 kilometers, which is more than 20 kilometers higher than the limit of Dayang Group's previous hydrogen balloon exploration!

At this height, the aura can be almost ignored, and a little aura can no longer reduce gravity. And because there is no aura in the outside world, the true essence in the body seems to be dissipating slowly! Or 'escape'.

Lin Yinghao looked at the measuring instruments in the cabin, which showed that the gravity here is about 10.4 times that of the ground. Such a gravitational force made Lin Yinghao feel as if his body was filled with lead, and he didn't even want to move his fingers. Fortunately, as a young master in the Nascent Soul stage, he can still resist.

Hovering at this height for a while, Lin Yinghao finally had a chance to look sideways at the ground. Because of the design of the aircraft, it cannot be observed directly, but can only be viewed from the side. But all I saw was a vast expanse of whiteness.

"Where did I fly to?" Lin Yinghao scratched his head, he couldn't see the master who was following the plane directly below. And right now, the plane is still single-seater, and Lin Yinghao himself has no one to discuss it.

"Next time I will design a two-seater!" Classmate Xiao Lin scratched his wind-blown hair. Seeing that a quarter of the fuel was left, he controlled the plane and continued to climb.

Due to the reduction of fuel, the plane actually climbed another kilometer, but it could not climb to an altitude of 110 kilometers anyway.

The engine was roaring so badly that it had already started to vibrate. There was a long black tail trailing behind the plane, which was underburned fuel.

"It's the limit. 109.2 kilometers! Well, next time we'll hit the 110-kilometer altitude." Lin Yinghao muttered to himself, and the plane began to land.

But this time something went wrong.

When the plane is climbing, it can still see the ground and reference. But when the plane landed, Lin Yinghao... lost his frame of reference because of the vast expanse of whiteness below!

Flying in the sky, the most fearful thing is losing the frame of reference, which will make people completely lost. Think about being in an empty sky, you can't tell up, down, left, or right.

Especially when flying an airplane, it’s fine if you can’t tell left and right, but if you can’t tell up and down, hehe…

Too many aircraft accidents are caused by this.

Airplanes are not ships, and airplanes fly freely in the sky. Sometimes even with the ground as a reference, it is normal to tilt a dozen degrees.

At this time, Lin Yinghao encountered such a situation. In the vast sky, I no longer know where I am.

Lin Yinghao hesitated, and suddenly reduced the fuel, and the plane quickly entered a stall under the heavy gravity and began to fall. The direction of the plane's fall turned out to be the front left.

Lin Yinghao instantly determined the direction in his mind, and he was about to pull up the flaps and make adjustments. But the plane's power is too weak, the planet's gravity is too strong, and the plane... begins to circle!

"Not good!" Lin Yinghao was shocked. This is the world's first real test flight, and there is no experience in various aircraft and piloting skills. What Lin Yinghao can rely on now is his understanding of aircraft, familiarity with fluid mechanics and scientific knowledge.

He forced himself to calm down, and then made a decisive decision—accelerate along the direction of the plane's circling! Then fine-tune appropriately!

The aircraft engine was roaring, Lin Yinghao gradually pushed the power of the engine to the maximum. A spiral trail was left behind the plane.

The plane accelerated and fell faster and faster; but with Lin Yinghao's calm handling and the increase of air resistance, the plane finally gained lift again.

I don't know how long it has been since he was busy, and with the sound of the engine slowly and steadily, Lin Yinghao gasped with cold sweat on his face. The plane finally stabilized.

Looking at the altimeter of the plane, it was only 83 kilometers high. Just now, the plane fell down for a full 26 kilometers!

But after such a crazy driving experience, Lin Yinghao suddenly felt that he was in control of the plane.

There is a light flickering below, which is the instruction given by the master of the transformation stage following below.

The plane was running out of fuel, so Lin Yinghao controlled the plane to turn around and flew down slowly.

When the plane finally entered the aura layer, Lin Yinghao had the opportunity to wipe his back, already in a cold sweat.

"What happened just now?" Zhu Min, who followed the master, asked concerned while lying beside the plane.

"It's okay, it's just that the plane flew to a high altitude, couldn't see the ground, and lost its direction. When I go back, I have to think about it and install an instrument inside the plane that can indicate the horizon.

By the way, where are we now? "

Zhu Min nodded, and said, "Now the top of Yongchang County is the top of Xinglintang Group."

Just as he was speaking, there were already black spots approaching in the surrounding sky. If you look closely, you will find some god transformation stages, and flying boats.

A master next to Zhang Hao shouted: "Dayang Group is testing new technology, outsiders are not allowed to approach!"

The voice was loud and mighty, and the people who were about to approach stopped as expected. But some people did not stop, such as Zhou Shuhai.

Well, seeing Zhang Hao's father-in-law, everyone could only curl their lips, but they still tried their best to stop it.

Zhou Shuhai stopped one kilometer away and flew towards Dayang Group with everyone. Looking at the weird flying machine in front of him, Zhou Shuhai couldn't help asking: "What is this?"

"Airplane! A kind of flying machine!" Zhu Min was a little excited. After studying for so many years, he was exhausted.

"Oh..." Zhou Shuhai replied in a daze, then stared blankly at the plane and Lin Yinghao in the plane, not knowing what to say for a moment.

The strange thing in front of him obviously surpassed the comprehension ability of the old man. From Zhou Shuhai's eyes, it can be seen that the thing didn't need to use formations, spells, etc., and it flew completely by mechanical power.

Just, how is this done?

The plane was flying forward at a speed of 800 kilometers per hour, protected by more than a dozen transformation stages of the Dayang Group on both sides; while more and more transformation stages were coming around.

Everyone looked at the weird machine in front of them in a daze.
