"No brother, who the hell are you!"

At this moment, A Zhuang couldn't bear it any longer and stared at the incomprehensible man in front of him with his eyes closed.

This guy came out of nowhere.

Never seen it at all!

However, from the moment this product appeared, he felt relaxed and integrated into the environment perfectly. The feeling of relaxation was like returning to his own home.

This made A Zhuang lose his confidence for a moment, and he couldn't figure out who this was after thinking for a long time.

after.

This guy first called Brother Face a brother-in-law, and then joked with Erzhuzi very naturally. Just now, he was chatting and laughing with Li Ningning as if they had a good relationship!

Okay, he has tolerated this. Many people in this world are just familiar with each other and treat them as their own home wherever they go.

But now I just slapped my nose on my face, with a natural expression like "How can you not call me when you are doing activities?", and started to reach out for equipment.

"This is no joke, it could cost someone's life! Besides, can you skydive?"

"Of course I will."

Lin Xian replied:

"Of course I know the danger, but none of us in the Face Gang have ever been afraid of death."

"Who, who, and you and us!"

A Zhuang looked at Lin Xian suspiciously:

"Do you know what we're going to do?"

"You know, isn't it just about parachuting into the Rhine Sky City to find medicine to prevent or treat radiation sickness? Don't worry, I have experience flying in a wingsuit at an altitude of 20,000 meters."

Lin Xian started to brag.

The wildest time I played in the dreamland was just wingsuit flying and skydiving at an altitude of several thousand meters, and the maximum was no more than 10,000 meters.

It's not that he doesn't dare.

The main reason is that such an opportunity cannot be found in the dream... After all, the first dream is also the real future world 600 years later. Except for those people sponsored by Red Bull "I pay you to die", where can you find such ultra-high altitudes? A chance to skydive?

Even if he falls asleep at the earliest time every day, he can only stay in the dream for 12 hours. There is not enough time to implement overly complicated actions and plans.

"You have thought about it."

A Zhuang asked:

"You saw what happened to Brother Face just now. If it's a little skewed, as long as it touches the area outside the gap of the air defense network, it will be immediately targeted by the laser and evaporated instantly."

"And once this helium balloon enters an altitude of 20,000 meters, there is no possibility of coming back down. It will keep rising until it enters outer space and explodes. So if you want to give up halfway, there is no turning back."

"Don't worry, don't worry."

Lin Xian urged A Zhuang to hold on tighter.

He just looked at his watch. It was already past 11 p.m.

The speed at which a hot air balloon takes off is very slow. Coupled with the preparation time and skydiving time, even if you are lucky enough to successfully enter the Sky City, you will not have much time to explore, so you must seize the time.

soon.

Several women brought Lin Xian a complete set of skydiving equipment and handmade space suits.

These things themselves are not scarce.

What is truly scarce...is human life.

Nowadays, apart from the old, weak, sick, disabled and women, there are only three men left in the villages living on this side of the East China Sea.

After all these men fail and sacrifice...

It is up to them women to start learning and training in skydiving skills, and then when they are skilled in the skills, they will take the same risks as the sacrificed men.

This is what they have to do.

There is no medicine to treat radiation sickness, and the next ones waiting to die are their parents and their children.

No one can escape.

"Listen carefully, Lin Xian."

A Zhuang explained to Lin Xian while putting on a heavy space suit:

"Our target is above the square in the northwest city. Over the years, the only time we have successfully avoided the anti-aircraft laser was above this area. Therefore, there must be something in this direction.

Notched, this is the only safe place. "

Lin Xian looked at the map with red circles on the ground:

"I think the area of ​​this square is quite large. Is this gap that big too?"

"No."

A Zhuang shook his head:

"We don't know exactly where the gap is, because... no one came back alive. Based on the evaporation positions of those who died before, we only ruled out the possibility that there are gaps in the northeast and southeast directions. .

"But this information may not be accurate. No one knows how big the gap is. So... we can only try. I suggest that we both fly to the northwest. If we both die there, at least the back will be safe. For the second pillar and the third pillar, you can choose to break through in the southwest...this way the success rate is higher."

"good."

Lin Xian responded directly.

Sure enough, as he thought before, the location of the gap and the location that is not a gap are all information accumulated through countless lives and countless attempts.

The probability of my own success today is also very small.

But it doesn't matter...

This --\u003e\u003e

The endless loop of dreams is a natural trial and error field for me.

He can clearly remember the location of each death and avoid it the next time.

Just try it enough times.

One day, he will successfully land inside the Rhine Sky City.

This is his biggest advantage in dreams.

After countless attempts, even if the probability is only 1%, it will eventually be magnified to 100%.

"Get ready, take off!"

With the cable cut.

Staggering, the helium balloon pulled the manned basket, Lin Xian and A Zhuang, and slowly rose up in the dark night.

This was Lin Xian's first time riding a hot air balloon, which was very novel.

In the past, in dreams, even if I was skydiving or wingsuiting, I would take off in a skydiving plane.

The hot air balloon rose faster than Lin Xian thought, and it was getting faster and faster.

As the height rises.

The wind became stronger and stronger, blowing the helium balloon away from Sky City.

This was also the direction predicted from the beginning.

The action of invading Sky City is not something that can be carried out every day.

Weather and wind direction are important.

It doesn't matter if the hot air balloon floats away from the Sky City, as long as it glides horizontally for a while.

But if the wind direction blows the hot air balloon in the direction of Sky City...

It is very likely that before reaching the safe height, it touched the anti-aircraft laser area and directly GG.

gradually.

Lin Xian was getting higher and higher in the hot air balloon.

The crowd on the ground becomes one

Little bright spot.

The air also became cold and biting, and ice fog began to appear on the helmet's visor.

Fortunately, both Lin Xian and A Zhuang were carrying oxygen bottles behind their backs. The spacesuits were sealed, so the internal air pressure and oxygen content were fine, and the temperature was not very noticeable.

The view from a hot air balloon is similar to that of an airplane.

They had not been in the clouds for a while, and the surrounding clouds and fog were so thick that it was impossible to see anything clearly around them, nor clearly below.

But once you reach a certain height, your field of vision becomes instantly wider, and the clouds below become clear, and you can see the lights on the ground.

Lin Xian glanced at the altimeter next to him.

The current height is already 15,000 meters high.

The temperature is minus 37 degrees.

Looking up... the sky is gray, the moonlight is very bright, and there are some thin clouds visible above.

Lin Xian heard that if you look up at an altitude of more than 30,000 meters, you can see the dark space.

He doubted it for a while.

After all, the altitude of more than 30,000 meters is only the stratosphere of the atmosphere.

It's just that this altitude is still far away from space.

But...facts speak louder than words.

He has seen many videos of extreme sports, including those skydiving at altitudes above 30,000 meters. When the helium balloon rises, it is still sunny daytime, but once the altitude reaches 30,000 meters, the background behind it will indeed turn into pitch black space.

Is it because the atmosphere is too thin?

Lin Xian had not studied it carefully.

If there was such an opportunity, he really wanted to stand at an altitude of more than 30,000 meters, look up at the universe, and see if he could really see the curved contours of the earth and the dark space.

After a while...

The altitude indicator showed that the height of the helium balloon reached 17,000 meters.

This altitude has exceeded the flight altitude of all civil aviation aircraft, the temperature has approached minus 50 degrees, and the atmospheric pressure has dropped to one-tenth of the surface.

No living thing on earth can survive at this altitude. This is a forbidden area for life.

Leaving aside the temperature, just breathing normally is a luxury.

Above his head, even though Zhuang had been deflating the helium balloon, it still expanded to an extremely terrifying size.

Air pressure, something that is usually not even aware of its existence, can easily become a life-destroying force under certain circumstances.

finally!

The altitude rose to nearly 20,000 meters!

A Zhuang patted Lin Xian's helmet and motioned for him to look down——

The neon lights of the Rhine Sky City can be seen below.

This is really a highly developed city...

The traffic turns into a continuous stream of light, darting up and down the city like fireflies.

Following A Zhuang's instructions, Lin Xian locked the location of the central square.

Too... too small...

Looking down at an altitude of 20,000 meters, the lights in the square are only as big as a fingernail, but it can be regarded as a reference for the flight direction.

Lin Xian responded to A Zhuang with a clear gesture.

Then, A Zhuang waved to Lin Xian and jumped!

Whoosh!

Under the influence of gravity, Zhuang began to fall freely. He had obviously practiced it for a long time before. He stabilized his posture almost instantly, flattened his body, and began to glide forward. In the blink of an eye, he had already moved hundreds of meters away. distance.

Lin Xian followed closely and jumped!

Huhhhhhhhhhhhh!

A biting wind blew by.

After a brief feeling of weightlessness, Lin Xian felt a push up due to the force and friction brought by air resistance.

He did not rush to flatten his body like A Zhuang, but instead swooped down --\u003e\u003e

state, accelerating the fall.

He planned to catch up to A Zhuang's height first, and then follow him at a certain distance.

Lin Xian's wingsuit flying skills are quite good.

Freely controlling the posture and speed of gliding like this is just a basic skill.

Galileo conducted an experiment on the Leaning Tower of Pisa and overturned Aristotle's theory by letting two small balls of different masses fall at the same time. As a result, they landed at the same time.

so……

Many people may think that in the case of free fall in the air, it is impossible for the person who jumps out of the plane later to catch up with the person who jumps out of the plane first.

In fact, this theory is wrong.

Everyone who plays extreme sports knows that people and iron balls are different. Different body postures will greatly affect the falling speed.

And... because the air resistance will increase with the increase of the falling speed, as long as the height is enough, a person will eventually reach a mechanical balance, and then the accelerated fall will become a constant fall, and the speed will no longer accelerate.

This final speed is called terminal speed].

Generally speaking, the terminal velocity of an average female is about 50 meters per second; while the terminal velocity of an average male is about 90 meters per second.

That's right.

Although somewhat counter-intuitive.

But in fact, people who weigh more will eventually fall much faster than people who weigh less.

And if the posture is extremely graceful and other conditions are perfect, the terminal speed of human free fall can even reach more than 300 meters per second.

soon.

Lin Xian's falling height and speed had already caught up with A Zhuang, who had jumped off in advance. The two of them kept a fixed distance and quickly descended, gliding towards the square in the northwest area of ​​Rhine Sky City.

Close.

Close!

Ice began to condense on the goggles.

Even through the helmet, you can feel the howling of the cold wind during the high-speed descent!

Although it is still 10,000 meters away from the ground of Sky City, from the perspective of the rapid descent, this approaching speed is still very nervous.

Soon... the prize will be drawn.

Lin Xian deliberately leaned to the right side of the square, intending to look for the invisible "gap" in the prevention and control network from right to left.

If you die in battle this time, then when you come back tomorrow, lean a little to the left; if you still die, then lean a little to the left the day after tomorrow...

By eliminating it bit by bit, you will eventually be able to find the location of the correct gap.

Lin Xian stared at the approaching Rhine Sky City through his space helmet.

Here...

What is hidden?
