Chapter 225 Falling from high altitude
"If you are not my brother, who are you?"

At this moment, A Zhuang couldn't bear it anymore and looked at the strange man in front of him with his eyes wide open.

This guy came out of absolutely nowhere.

I have never seen it before!
However, from the moment this guy appeared, he was at ease and blended perfectly into the environment. The feeling of relaxation was like returning home.

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

after that.

This guy first treated Brother Lian as a brother, then joked with Erzhuzi very naturally, and just now he was even chatting and laughing with Li Ningning as if they had a very good relationship!
Well, he had to endure it. There were many people in this world who were really sociable and treated every place as their own home.

But now he is directly taking advantage of me, with an expression that says "Why didn't you invite me to your activities?" and starts asking for equipment.

"This is no joke, it could cost lives! Besides, can you parachute?"

"Of course I will."

Lin Xian replied:

"Of course I know it's dangerous, but there has never been anyone in our Face Gang who is afraid of death."

"So and so and so and you and us!"

A Zhuang looked at Lin Xian suspiciously:

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

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

Lin Xian started to brag.

The wildest thing I had done in my dreams before was wing suit skydiving at an altitude of several thousand meters, and the highest was no more than ten thousand meters.

It’s not that he doesn’t dare.

The main reason is that such an opportunity cannot be found in dreams... After all, the first dream is also the real future world 600 years later. Except for those people sponsored by Red Bull with the attitude of "I pay and you pay", where can you find such an opportunity for ultra-high altitude skydiving?
Even if he fell asleep at the earliest time every day, he could only stay in the dream for 12 hours. There was simply not enough time to implement overly complicated actions and plans.

"You have thought about it."

A Zhuang instructed:
"You saw what happened to Brother Lian just now. If you were even slightly off-center, as long as you touched the area outside the gap in the air defense net, you would be immediately targeted by the laser and evaporated instantly."

"And once this helium balloon reaches an altitude of 20,000 meters, there is no possibility of it coming back down. It will keep rising until it explodes in outer space. 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 and it was already past 11 o'clock in the evening.

The hot air balloon takes off very slowly, and coupled with the preparation time and parachuting time, even if you are lucky enough to successfully enter the sky city, you don’t have much time to explore, so you have to hurry.

soon.

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

The handmade space suit looks rather rough and certainly cannot be used in space, but it is sufficient for high-altitude skydiving.

Nowadays, in the village on the East China Sea, apart from the elderly, the sick, the disabled and women, there are only three men present.

After all these men have failed and sacrificed...

These women are required to start learning and training skydiving techniques, and then after they have mastered the skills, they will also take risks like the men who have sacrificed their lives.

This is what they have to do.

There is no medicine to treat radiation sickness, and the next people to die will be their parents and their children.

No one can escape.

"Listen carefully, Lin Xian."

As A Zhuang put on the heavy space suit for Lin Xian, he explained to him:
"Our target is the square above the northwest city area. Over the years, the only time we successfully avoided the anti-aircraft laser was above this area. Therefore, there must be a gap in this direction, and this is also the only safe place."

Lin Xian looked at the map with a red circle on the ground:
"The area of ​​this square seems to me to be quite large. Is the gap also that big?"

"Do not."

A Zhuang shook his head:
"We don't know exactly where the gap is, because... no one has come back alive. Based on the locations where the dead people evaporated, we have 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 northwest. If we both die there, at least Erzhuzi and Sanpang behind us can choose to break through in the southwest... This way the success rate will be higher."

"it is good."

Lin Xian agreed directly.

As he had thought before, the location of the gap and the location that was not a gap were all information accumulated through countless lives and countless attempts.

The probability of my life succeeding today is also very small.

But never mind...

This infinitely repeating dream is a natural trial and error field for me.

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

Just try enough times.

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

This is his greatest advantage in the dream.

"Ready, take off!"

As the cable was cut.

With a stumble, the helium balloon pulling the manned basket, carrying Lin Xian and A Zhuang, slowly rose in the darkness.

This was Lin Xian’s first time riding in a hot air balloon, and it was quite new.

In the past, even when I was skydiving or wingsuit flying in my dreams, I would take off in a skydiving plane.

The hot air balloon was rising a little faster than Lin Xian had expected, and it was getting faster and faster.

As the altitude increases.

The wind was getting stronger and stronger, blowing the helium balloon away from the sky city.

This was also the wind direction predicted at the beginning.

The invasion of Sky City is not possible every day.

Weather and wind direction are important.

It doesn't matter if the hot air balloon floats a little away from the sky city, it can just glide horizontally for a while longer.

But if the wind blows the hot air balloon towards the Sky City...

It is very likely that the aircraft will touch the anti-aircraft laser area before reaching the safe altitude, and it will be a complete failure.

gradually.

Lin Xian was riding the hot air balloon higher and higher. The crowd on the ground became a small bright spot.

The air also became cold and biting, and icy fog began to appear on the helmet goggles.

Fortunately, Lin Xian and A Zhuang both carried oxygen tanks on their backs. The space suits were sealed, so the internal air pressure and oxygen content were fine, and the temperature was not very obvious.

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

There was a period of time when we were not in the cloud layer. There was thick fog all around and we couldn't see anything clearly around us or below us.

But once you reach a certain height, the view will suddenly become wide, the clouds below will become clear, and you can see the lights on the ground.

Lin Xian glanced at the altimeter next to him.

The current altitude is 1 meters.

The temperature is minus 37 degrees.

Looking upwards... the sky was grey, the moonlight was bright, and you could see there were some thin clouds above.

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

He once doubted this matter.

After all, an altitude of more than 30,000 meters is only the stratosphere of the atmosphere, and this altitude is still far away from space.

But...facts speak louder than words.

He has watched many videos of extreme sports, including those of skydiving above 30,000 meters. When the helium balloons rise, it is still a sunny day, but once the altitude reaches 30,000 meters, the background behind them will indeed turn into the pitch-black space.

Is it because the atmosphere is too thin?
Lin Xian has not studied it seriously.

If there was such an opportunity, he would really like 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 outline of the earth and the dark space.

After a while...

The altitude indicator showed that the helium balloon had reached an altitude of 1 meters.

This altitude has exceeded the flight altitude of all civil airliners. The temperature has approached minus 50 degrees Celsius, and the atmospheric pressure has dropped to one tenth of that on the surface.

No living creature on Earth can survive at this altitude; this is a forbidden zone for life.

Not to mention the temperature, just breathing normally is a luxury.

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

Air pressure, something that we are usually not aware of its existence, can easily become a force that destroys life under certain circumstances.

at last!

The altitude rose to nearly 2 meters!

A Zhuang patted Lin Xian's helmet, signaling him to look down -

The Rhine Sky City with its bright neon lights can be seen clearly below.

This is really a highly developed city...

The traffic turned into long streaks of light, shuttling through the city like fireflies.

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

Too... too small...

Looking down from an altitude of 20,000 meters, the lights in the square are only as big as a fingernail, but it does provide a reference for the direction of flight.

Lin Xian responded to A Zhuang with an understanding gesture.

Then, A Zhuang waved to Lin Xian and jumped!
Whoosh!
Under the influence of gravity, A Zhuang began to fall freely. He had obviously practiced this for a long time before. He stabilized his posture in almost an instant, stretched his body, and began to glide forward. In the blink of an eye, he had opened up a distance of hundreds of meters.

Lin Xian followed closely behind and jumped!
Whoosh whoosh whoosh whoosh whoosh!
The cold wind whistled past.

After a brief feeling of weightlessness, the support and friction caused by air resistance made Lin Xian feel a sense of upward push.

He did not rush to stretch his body like A Zhuang, but instead dived down and fell at an accelerated speed.

I planned to catch up with A Zhuang’s height first, and then follow him at a certain distance.

Lin Xian’s wing suit flying skills are pretty good.

Freely controlling the gliding posture and speed like this is just basic skills.

Galileo conducted an experiment on the Leaning Tower of Pisa, in which he dropped two small balls of unequal mass at the same time. As a result, they landed at the same time, thus overturning Aristotle's theory.

and 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.

Anyone who has played extreme sports knows that humans and iron balls are different, and different body postures will greatly affect the speed of fall.

And... because air resistance increases with the increase of falling speed, when a person falls from a high altitude, as long as the height is high enough, he will eventually reach a mechanical equilibrium, and the accelerated fall will become a uniform fall, and the speed will no longer increase.

This final velocity is called terminal velocity.

Generally speaking, the terminal velocity of women of average weight is about 50 meters per second, while the terminal velocity of men of average weight is about 90 meters per second.

People with heavy weight do fall much faster than those with light weight.

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

soon.

Lin Xian's falling height and speed had caught up with A Zhuang who had jumped down earlier. The two of them maintained a fixed distance and descended quickly, gliding towards the square in the northwest city of Rhine Sky City.

Nearly.

close!

Ice began to form on the goggles.

Even through the helmet, you can feel the whistling of the cold wind as you fall at high speed!
Although it is still ten thousand meters away from the ground of Sky City, the visual of the rapid descent makes the approach speed still very nervous.

Soon... the prize drawing will begin.

Lin Xian intentionally moved to the right side of the square. He planned to look for the invisible "gap" in the prevention and control network from right to left.

If I die in this battle, I will move a little to the left when I come back tomorrow; if I die again, I will move a little more to the left the day after tomorrow…

By eliminating little by little, one day you will find the correct gap.

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

Here...

What is hidden?
