In the stratosphere, not only is the airflow stable, but even the temperature is relatively stable.

And the air here is pure, with almost no impurities, and you can see a clear and bright sky, and the blue sky is so fascinating. Every breath of air is a rare treat. Of course, the premise is that you can withstand the low temperature of minus fifty or sixty degrees Celsius.

Wang Yan's physique has long surpassed that of ordinary people countless times. Even at such low temperatures, he is calm and without discomfort.

The height of the stratosphere is about ten kilometers above sea level to thirty kilometers above sea level. Wang Yan has now flown to more than ten kilometers above sea level, but because of the pure climate near the equator, visibility is quite high.

He can still enjoy the majestic magnificence of Mount Kilimanjaro and the tragic and desolate beauty of the Great Rift Valley of East Africa.

This is the beauty of the world, Wang Yan's heartfelt admiration.

Unfortunately, there is not much time left for him, he must leave here immediately. Wang Yan's devil's wings struck hard, and the speed suddenly increased by a few more points, following the rotation of the earth, and continued to climb upwards in an oblique tangent.

As you fly upward, the temperature begins to rise gradually. Because the ozone content in this layer of atmosphere is very high, it absorbs a lot of solar ultraviolet bands that are harmful to humans, which results in higher temperatures. When it reaches the top layer, the temperature can reach about zero degrees.

If ordinary people are exposed to those harmful ultraviolet bands, it will have a great impact on health. And Wang Yan is a strong A-class, his physical physique is already very strong, plus he can use energy to cut off ultraviolet radiation. Therefore, no matter how strong ultraviolet rays affect him.

The remaining ten kilometers of stratosphere was broken by Wang Yan in a short time.

In just a moment, Wang Yan cut into the third layer of the atmosphere-the middle layer.

This layer of the atmosphere is already an absolute exclusion zone for the vast majority of life on Earth. Only a rocket will allow the spacecraft to set foot in this area. Of course, there are powerful superpowers like Wang Yan.

But not all superpowers can come to this level. The last time Wang Yan was B-level, there was no way to break through to this level. Here, the air became thinner and thinner, and Wang Yan's demon wings gradually became useless.

The air is too thin, and flapping the wings can't get enough power. In order to maintain the momentum to resist gravity, Wang Yan must stir up the pure Yang Qi and fly by Qi Qi.

However, the consumption of imperial flying in unit time is far more than that of flying with wings. Therefore, in order to save power, Wang Yan sacrificed the "anti-gravity device" obtained from the Sun Temple.

Under the influence of his mental power, the crystal ball radiated a golden light. Those golden lights converged into a deformable golden bubble that enveloped Wang Yan.

Suddenly, Wang Yan felt that his body was light, and the speed of his flight suddenly increased a lot, and he flew to the sky more and more quickly.

At the bottom of this middle layer, the temperature is okay, only a few degrees below zero. However, as you fly upward, the temperature drops abruptly, and Wang Yan is experiencing a process of rapid temperature drop.

This is how the atmosphere changes. Some areas are hotter and hotter, and some areas are hotter and colder.

boom!

Wang Yan is like a rocket launcher, and it shuttles into the warm atmosphere from the top of the middle layer. The warm layer is also called the hot layer. This is a very peculiar layer of the atmosphere, few humans can get involved.

The temperature of this layer will continue to increase with height. The air is extremely thin. Wang Yan is now over a hundred kilometers high. Here, the air density is so diluted that even the sound can't be transmitted.

And the air is extremely thin, and there is a fatal danger. Because human beings naturally live at the bottom of the atmosphere, the pressure in the body adapts to the pressure at the bottom of the atmosphere.

The balance between external air pressure and internal air pressure must be achieved in order to live a normal life. Once the external air pressure weakens or disappears, the pressure in the body will expand outwards, exploding like a toad.

Even ordinary people have no chance of exploding, because before that time, the heart was squeezed, and the brain squeezed and died.

In fact, before Wang Yan flew more than 100 kilometers, he gradually felt the slight expansion of his internal organs. But his physique is far superior to ordinary people, and every cell in the body tissue is very strong and tough.

But even so, it is impossible to fully withstand the thinner and thinner air, the pressure expansion of the body brought about by the feeling. He had to spend a part of his strength to form a pure barrier of pure yang true qi outside the body to maintain the balance of body pressure.

This is like a human wearing a space suit when he is in outer space. One of the functions of the spacesuit is to maintain the balance of pressure inside and outside the body.

But the thin air also has the benefit of thinness. At least when flying, there is no need to be restricted by air resistance to limit the speed. In theory, Wang Yan has an "anti-gravity device" that can offset the gravity of the earth, and there is no air resistance. As long as he has a continuous source of power, the energy source continues to accelerate.

Of course, this is just theory. After all, Wang Yan's power is limited, no matter how powerful it is. He not only needs to accelerate, but also needs to restrain this harsh environment, and the power loss is always great.

He couldn't just continue to accelerate and fly home, he needed transportation.

That's right, it's transportation.

In this warm layer, Wang Yan is now more than 120 kilometers away from sea level. Theoretically, even the most advanced aircraft is far from being able to reach this altitude. Because the air here is so thin that it can't support the wings and float at all, there is no way to **** in enough air to spray and obtain the reaction force.

Therefore, many people think that there will be no means of transportation at this height for Wang Yan to take a free ride home.

But it was wrong.

In this warm layer, there are countless man-made vehicles.

satellite.

To be precise, it is an artificial satellite. This is the real plan for Wang Yan to return home this time.

In 1957, the Soviet Union launched the world's first artificial satellite.

After that, various countries launched artificial satellites at a distance. Our country, Huaxia, also launched its first artificial satellite in about 1970.

Until now, launching artificial satellites has become commonplace. Not to mention some national systems, even a company with a little strength will lose some satellites to the sky.

It can be said that the number of satellites in the sky today is far more than ordinary people imagine.

There are at least thousands of artificial satellites that are in operation or have been scrapped but still in orbit. In addition, there are a lot of space debris in the sky flying day after day.

In fact, Wang Yan's main targets are scrapped satellites and large space junk. Because those things have been damaged and scrapped, and they have lost their power source, they will gradually lower their altitude because of the stall while flying around the earth day after day.

According to scientific theory, man-made objects rely on inertia with a minimum surrounding altitude of 120 kilometers. Below this altitude, they will quickly fall into a high-density atmosphere and burn up in friction.

The number of large space debris and the number of discarded satellites are many, at least 20,000 in the entire orbit. Among the countries that contributed the most to these space junk, Russia ranked first, the United States ranked second, and our China country ranked third.

Although it is not necessarily a glorious thing, it can be seen that the production of space junk is also related to the strength of the country.

Of course, these are off-topics.

Wang Yan now needs to find a scrapped satellite, or enough space to carry his own space junk. This is why he had to run to the equator, because of all the satellites, he ran the most around the equator.

In other words, this is a busy transportation line, and the easiest to catch a free ride.

However, whether it is a satellite or not, space orbit junk. It is not easy to ride them, because they are very fast, reaching 7.9 kilometers per second.

The reason why the data is accurate is that if they are lower than the speed of 7.9 kilometers per second, they will fall around quickly. If it is higher than the orbital speed, then they will fly away from the earth.

The speed of 7.9 kilometers per second is a very exaggerated data, which is seven or eight times the initial speed of the sniper rifle bullet, and more than 20 times the speed of sound. At this speed, even a small piece of debris, the kinetic energy lethality is huge.

Even if Wang Yan was hit positively, he would have to lose half his life without dying. Of course, if Wang Yan is hit by a satellite weighing hundreds or thousands of kilograms while still, he can basically say goodbye to the world.

When Wang Yan was a child, he watched an anti-Japanese drama, called "Railway Guerrilla."

Those members of the military team are very good at picking up trains. There is a special trick to picking up trains, that is, you have to run in the direction of the train to reduce the relative speed of both sides as much as possible.

The smaller the relative speed, the safer it is.

Therefore, Wang Yan is constantly accelerating in the direction of the rotation of the earth at a height of one hundred and dozens of kilometers, from the west to the east. In the case of extremely low air content, it is already close to vacuum, and the factor of air resistance is less.

As long as the force is continuously applied, Wang Yan's speed is rising. He easily broke twice the speed of sound and triple the speed of sound. Moreover, because the air is extremely thin, it is equivalent to no air, and even the sound barrier when it breaks through the speed of sound does not exist. Flying in this environment and flying close to the ground are completely two concepts.

But at the same time, Wang Yan's power was also rapidly consumed. Fortunately, there is an "anti-gravity device" that helps offset the gravity factor.

Suddenly.

Something quickly passed him from a few hundred meters to the left of Wang Yan, and disappeared in his sight in just one second. I was shocked by Wang Yan's cold sweat, and I shouted it. I didn't see what it was just now. Is this too fast?

It seems that pulling a satellite or hitchhiking in space junk is harder than expected. Be careful, don't just die if you die.
