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

And the air here is pure, there are almost no impurities, and the sky is clear and bright, and the blue sky is intoxicating. Every breath of air is a rare treat. Of course, the premise is that you can withstand the low temperature of minus 50 or 60 degrees Celsius.

Wang Yan's physique has long surpassed that of ordinary people countless times, even at such low temperatures, he is calm and has no discomfort.

The altitude of the stratosphere ranges from about 10 km above sea level to 30 km above sea level. Wang Yan has now flown to an altitude of more than ten kilometers, but because the climate near the equator is pure, the visibility is quite high.

He could still admire the majesty of Mount Kilimanjaro and the tragic and bleak beauty of the Great Rift Valley.

This is the beauty of the world, Wang Yan admired from the bottom of his heart.

Unfortunately, time is running out for him, and he must get out of here immediately. Wang Yan's demonic wings shook hard, and his speed suddenly increased by a few points, and he rotated along the earth, continuing to climb high into the air in an oblique tangent line.

The higher you fly, the temperature starts to rise gradually. Because the ozone content in this layer of the atmosphere is very high, it absorbs a large number of ultraviolet band of the sun, which is harmful to humans, resulting in high temperatures, and the temperature can reach about zero degrees at the top level.

Exposure to harmful ultraviolet rays can have a devastating impact on the health of ordinary people. And Wang Yan, as an A-level powerhouse, is already very strong in his own physique, plus he can completely use his strength to isolate ultraviolet radiation. Therefore, no matter how strong the ultraviolet rays are, it will not affect him much.

The remaining height of the stratosphere was more than ten kilometers, and it was broken through by Wang Yan after a while.

In just an instant, Wang Yan cut into the third layer of the atmosphere, the middle layer.

This layer of the atmosphere is already an absolute forbidden area for the vast majority of earth creatures. Only rockets, spacecraft will set foot in this area. Of course, there are also powerful superpowers like Wang Yan.

But not any superpower can come to this layer, the last time Wang Yan was still B-level, there was no way to break through to this layer. Here, the air became thinner and thinner, and Wang Yan's demonic wings gradually began to be useless.

The air is so thin that there is no more power to flap the wings. In order for Wang Yan to maintain the momentum to resist gravity, he must stir up the pure yang true qi and fly with the qi.

However, the cost of flying in a unit of time is much greater than 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 spiritual power, the crystal ball emitted golden light. Those golden rays of light converged into a transformable golden bubble, enveloping Wang Yan in it.

Suddenly, Wang Yan felt that his body was light, and his flying speed suddenly increased a lot, and he flew higher and faster into the air.

At the bottom of this middle layer, the temperature is okay, only a few degrees below zero. But the higher he flies, the temperature drops sharply, and Wang Yan is experiencing a rapid drop in temperature.

The atmosphere is so varied, with some areas being higher and hotter and some areas being taller and colder.

Rumble!

Wang Yan is like a rocket launcher, shuttling from the top of the middle layer to the warm layer of the atmosphere. The warm layer, also known as the hot layer. This is an extremely peculiar layer of the atmosphere that few humans have ever been able to set foot in.

The temperature of this layer increases with the altitude. The air, on the other hand, is extremely thin. Wang Yan has now flown more than 100 kilometers high, and here, the air is so dense that even sound cannot be transmitted.

And the air is extremely thin, and there is a mortal danger. Because humans are creatures that naturally live at the very bottom of the atmosphere, the air pressure in the body adapts to the air pressure at the bottom of the atmosphere.

It is necessary to achieve a balance between the external air pressure and the internal air pressure in order to live a normal life. Once the external air pressure weakens or disappears, the pressure in the human body expands outwards and explodes like a bulging toad.

Even, ordinary people don't even have a chance to explode, because they died long ago because of heart squeezing, brain squeezing or something before that.

In fact, before Wang Yan flew more than 100 kilometers ago, he had already gradually felt the feeling of slight expansion of his internal organs. It's just that his physique is far beyond that of ordinary people, and every cell in his body tissues is very strong and tough.

But even so, it is impossible to fully withstand the feeling of air pressure expansion in the body brought about by the increasingly thin air. He had to expend some of his strength to form a thin barrier of pure yang true qi outside his body to maintain the balance of pressure in his body.

It's like humans donning a spacesuit when they're in outer space. One of the functions of the spacesuit is to maintain the balance of internal and external pressure.

But thin air also has the benefit of being thinner. At least when flying, there is no need for air resistance to limit speed. Theoretically speaking, Wang Yan has an "anti-gravity device" that can cancel out the earth's gravity, and without air resistance, as long as he has a steady source of power, he will continue to accelerate.

Of course, this is just a theory. After all, no matter how strong Wang Yan's strength is, it is limited. Not only does he need to accelerate, but he also needs to restrain this harsh environment, and his strength is very depleted at all times.

He couldn't just keep speeding up and flying home, he needed transportation.

That's right, it's transportation.

In this warm layer, Wang Yan was already more than 120 kilometers away from the sea level at this time. Theoretically, even the most advanced aircraft is far from being able to fly to such heights. Because the air here is so thin that it can't support the wings to float in the air, and there is no way to inhale enough air to spray and gain reaction force.

Therefore, many people think that there will be no transportation at this altitude for Wang Yan to hitchhike home.

But it's wrong.

In this conservatory, there are countless man-made vehicles.

Satellite.

Sputnik, to be exact. This is Wang Yan's real plan to go home this time.

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

After that, countries launch satellites from along. Around 1970, China launched its first artificial satellite.

By now, the launch of artificial satellites has become commonplace. Not to mention some national systems, even companies with a little bit of strength will throw some satellites into the sky if they have nothing to do.

It can be said that the number of satellites in the sky today is far beyond the imagination of ordinary people.

Some satellites that are in operation, or have been scrapped, but are still in orbit, must be in the thousands. In addition, there is a large amount of space junk debris, which is flying in the sky day after day.

In fact, Wang's main targets are scrapped satellites and large space junk. Because those things have been damaged and scrapped, and have lost their power, they will gradually lose altitude due to stalls as they fly around the earth day after day.

According to scientific theories, man-made objects rely on inertia to orbit at a minimum altitude of 120 kilometers, below which they will quickly fall into the dense atmosphere and burn up in friction.

The amount of large space junk and the number of scrapped satellites is very large, and there must be at least 20,000 pieces in the entire orbit. Among them, the country that contributes the most to these space junks is Russia, the United States is second, and the third is our Huaxia.

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

Of course, these are all off-topic.

Wang Yan now needs to find a scrapped satellite, or enough space junk to carry it. This is also the reason why he runs around the equator, because of all the satellites, it runs the most around the equator.

That said, it's a busy traffic line and it's easiest to catch a ride to work.

However, whether it is a satellite or a 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 because if the speed is less than 7.9 kilometers per second, it will quickly fall around it. If it is higher than the orbital velocity, then they will fly away from the Earth.

A speed of 7.9 kilometers per second is a very exaggerated figure, which is seven or eight times the muzzle velocity of a sniper rifle bullet and more than 20 times the speed of sound. At this speed, even a small fragment can produce a tremendous amount of kinetic lethality.

Even if Wang Yan is hit head-on, he will have to lose half his life if he doesn't die. Of course, if Wang Yan is in a stationary state and is hit by a satellite weighing hundreds or thousands of kilograms, he can basically say goodbye to the world.

Wang Yan watched an anti-Japanese drama called "Railway Guerrillas" when he was a child.

Those members of the martial arts team are very good at picking up trains. One of the tricks of picking up the train is that you have to run in the direction of the train, reducing the relative speed of both sides as much as possible.

The smaller the relative velocity, the safer it is.

Therefore, Wang Yan was at an altitude of 100 kilometers and was accelerating in the direction of the earth's rotation, that is, from west to east. In the case of extremely low air content, it is already close to vacuum, and there is less air resistance.

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

But at the same time, Wang Yan's strength was also rapidly depleting. Fortunately, there are "anti-gravity devices" that help counteract the gravity factor.

Suddenly.

An object quickly overtook him from a few hundred meters to Wang Yan's left, and in just a second, it disappeared from his sight. Wang Yan was shocked into a cold sweat, I'll strangle it, I didn't see what it was just now, this speed is too fast, right?

It seems that hitchhiking a satellite or space junk is a little harder than you think. You have to be careful, don't get crippled and killed.
