Chapter 236 City in the Sky—Take off!

Two tense months passed quietly.

The day when the Sky City is about to rise has finally arrived!

It was an ordinary day full of sandstorms.

It was dawn, and everyone was awakened by the emergency bell.

The hot wind and sand blew on my face, but it couldn't extinguish my passionate heart.

The power system of the Sky City is actually quite ordinary. The power provided by humans is seriously insufficient, causing the city's flight speed to be extremely slow.

The wind push of the sandstorm is actually a good supplement.

Before four o'clock, Lu Yuan got up early. He was in a good mood. He wore an exquisite dress left by the green civilization, which was a bit like a tuxedo. The exquisite leaf pattern brought a sense of splendor.

Miss Conch was also dressed beautifully, wearing a lace round-neck sweater and a floral skirt, which outlined her slender waist and bulging chest.

There is also a pink poppy flower on her head, which looks playful and cute.

"Why don't you show up in public? Why are you dressed up so beautifully?" Lu Yuan glanced at her several times. The pretty girl was indeed pleasing to the eye.

"This scene should be recorded in the green paradise to educate future generations!" The conch jumped, holding a small flower and wearing it on Lu Yuan's chest, smiling and saying, "General, I hope the city will not fall!"

Lu Yuan immediately stretched out his hands, twisted her hair into a ball, and ran away happily amidst the girl's anger.

Five o'clock in the morning.

Various work groups have already had breakfast in the cafeteria.

Today, the cafeteria lady's hands are no longer shaking, and the portions of food are very generous.

Everyone was talking and laughing, and there was a warm sense of anticipation in the air.

At half past five in the morning, the large army also gathered. The elderly and children were all dressed in their best clothes.

Lu Yuanda said loudly: "Friends, today is the day to test the fruits of labor. Let us look forward to the harvest after our hard work."

"The City in the Sky officially takes off today!"

Waves of cheers spread throughout the city.

The winding vines of the poppy tree spread to every corner of the city, blooming green leaves one after another, emitting a faint green light.

The entire Sky City's heritage has been piled into the inner ring.

Whether they are useful or useless, every warehouse is filled with them.

There are even some large objects that cannot be stacked at all and can only be left in the open air.

"Oil reserves, totaling 1.68 million cubic meters."

"The electric unit is operating normally!"

"The metal warehouse stores a total of 21.82 million tons of metal."

Lu Yuan counted the assets and found that they were really full and could not be filled at all.

The time has come to test the final results. Everyone has been working hard for this day for a year and six months, but whether it will succeed or not is still unknown...

"I order all civilians except the working group to leave the Sky City! Temporarily evacuate to surrounding villages."

"Led by Sha Kan'er, don't leave any people behind on the way!"

"Understood!" Shakaner saluted and mounted the giant insect "Drawer".

There were more than a thousand villagers sitting on the back of each "Drawer", marching in the direction of the village.

This is of course for safety.

If the Sky City fails to rise and falls in mid-air, they still have a chance to survive.

"The three of you will keep an eye on me to avoid accidents."

"I have the ability to protect myself."

The three king insects bowed slightly: "Yes!"

Flap your wings and leave.

The "Drawer" moved very quickly in the desert, covering more than 30 kilometers in less than half an hour.

The dark crowd stood on the insect's back, looking eagerly toward the horizon.

People are anxious but full of expectations.

Suddenly, Lu Yuan's voice came from the remote intercom: "I order...the City in the Sky and the City of Green to officially take off!!"

"Countdown, ten seconds..."

"Ten, nine, eight, seven..."

As the countdown ends, this city that has been sinking for four thousand years has completely recovered at this moment!

"Boom"!

The sky collapsed and the earth trembled.

Huge amounts of dust flew up one after another, forming a huge air wave that pushed in all directions like a tsunami.

People heard the intermittent conversations of various work groups on the intercom.

"Report! The power grid is stable...the generator set is normal!"

"The poppy tree is fairly stable and the energy circuit system is normal."

"The Pandora crystal anti-gravity system is officially activated, and the gravity of the rock is being offset... There is a small amount of abnormal suspension phenomena, and the speed of rise is somewhat abnormal."

People's hearts were clenched. They didn't understand what "abnormal suspension" meant. It was just a heart clenching tightly.

…

Lu Yuan and others in the center of the city were also breaking out in cold sweats, probably because the energy output was a bit high, and the city was rising too fast. They flew up like birds, and many people fell directly to the ground!

The construction of Sky City is a systematic and large-scale project.

After offsetting the gravity of the rock, the city will be lifted up by atmospheric pressure and suspended like a balloon. (The non-rock part cannot offset it.)

At this time, it is required to retain a little gravity so that the urban gravity and atmospheric buoyancy remain relatively stable.

"There are some errors in the original city tonnage calculation, which is reducing the energy output of the anti-gravity system."

"The abnormal levitation phenomenon is disappearing. The current height is 250 meters...260 meters...270 meters."

"The city currently remains stable."

I don't know whether it was because of nervousness or excitement, but the crowd of people watching was silent, but their eyes widened.

They watched as the cloud of dust grew larger and larger, spreading in all directions like a mushroom cloud from a nuclear bomb explosion.

"I saw the City in the Sky! Haha!" Suddenly, a sharp-eyed young man shouted, "It's really flying!"

"Can we escape the desert?"

More and more people are seeing that city.

"Blessed by our ancestors, stones can really fly." Shakaner murmured to himself. He put a hand on his eyebrows and saw a cube-like thing slowly rising from the mushroom cloud, flying higher and higher.

The rest of the people also held their breaths without blinking, cheering and lively discussions mixed together.

At this moment, beyond the horizon, the red sun is rising in the east.

This is a sunrise that shocks the past and present!!

Along with the slowly rising red sun, the City in the Sky also rose together, bathing in the vast sunlight.

There has never been such a gentle light in the world. Even the sun today seems to be drunk and not so fierce, dyeing the entire sky a drunken red.

More and more people see the rising city in the sky, and suddenly tears of happiness flow from their eyes!

They did it, they... were able to leave this desert.

The people soon became a sea of ​​joy and celebrated loudly.

Some people's joy is because they escaped and ascended to heaven. In fact, they did not participate too much, they were just shocked... It is really amazing that a stone city can actually rise.

There are also some people who are moved by their own efforts, when they think of the days and nights of study, struggle, and practice, and that everything was achieved from scratch through labor.

They really paid a lot for this operation.

They suddenly felt that just for this minute of touching, everything, all the blood and sweat were worth it!

This kind of touch, this kind of joy, is not because living conditions have been improved, nor is it because the threat of death has been escaped, but because a kind of ideal has been realized.

They are not only happy, but also deeply proud.

…

…

"The current altitude is 14,000 meters...the city has good stability and low turbulence."

At this moment, Lu Yuan stood at the highest point of the poppy tree, looking down at the vast desert, feeling suddenly heroic.

This scene is truly shocking!

The solitary smoke rises straight up in the vast desert, the rising sun is round in the endless sky, and the rough wind and sand are trampled under my feet. There is a heroic feeling that the world is in my hands.

The mass of the Sky City is about 160 million tons, which is many times more exaggerated than the aerospace aircraft carrier in science fiction novels.

It is indeed impossible for pure physical technology to raise such a behemoth.

But Weixin Technology did it!

As the gravity of the rock disappears, the city continues to rise.

The thickness of Pangea's atmosphere is much higher than that of the Earth, and 14,000 meters will not cause hypoxia problems.

According to the information of Greenland Civilization, there is strong spiritual interference above the atmosphere, and the Pandora crystal may fail, causing the anti-gravity system to lose control; if the altitude is too low, it may be attacked by monsters.

Therefore, the general lift-off height is between 20,000 and 30,000 meters, which is a very comfortable range. Even if you are unlucky and encounter natural disasters such as "ghosts and monsters", as long as these guys cannot fly, they may not be able to come up.

"I order to stabilize the altitude to 20,000 meters."

"Start the power system! Head towards the village!"

[Look at how proud you are. Fortunately, you are dressed beautifully and have a sense of ceremony!] As the controller of the poppy tree, Conch takes a break from busy work to send telepathic messages.

"You can't be complacent about such a big baby rising."

"Boom!"

Several giant propellers began to rotate and push the city forward - these things were like wind turbines, the blades alone were hundreds of meters long.

Its maintenance is very complicated, and currently it is only done by a few owners of "craftsmanship".

Lu Yuan was worried that these propellers would fall apart midway.

The giant propeller roared and creaked, and it was moving, giving it a steampunk aesthetic.

"The sandstorm has a speed of 57 kilometers per hour and can produce a small amount of propulsion."

"The current speed of Sky City is 0.09 kilometers per hour, and the direction is 43.8 degrees east-south."

Okay, this speed is indeed very slow.

Even if the gravity is offset, the huge inertia is real and requires a slow acceleration process.

If you want to fly faster, you need some glyphs to reduce the friction of the air, the jet power system, and other miscellaneous things - of course this is a big project, and Lu Yuan doesn't have the time or energy to do it for the time being.

"Desert, how are you doing there? Can the generator handle it?!" Lu Yuan asked on the intercom.

The balance of the Sky City and the operation of the propellers are projects supervised by Lao Mao himself, so they are considered stable.

The power station and power network are personally supervised by the current number one wise man, the "Super Thinker", Desert.

After all, he has only studied for two or three years. No matter how smart he is, everyone is still worried about his ability...

Yes, even Shamo himself is worried, afraid that he will not be able to complete the task!

But there is no way.

Now there is no talent at all. There is only one smart old cat and only one conch. He cannot wear multiple hats. He can only rush to the shelves!

"I'm checking the machine's parameters!"

He clenched his hands into fists, and his entire palms were turning blue and purple. Looking back on the past day, he felt sad.

He led others to repair the generator, because the original instrument was seriously damaged and had to be dismantled and repaired, and then he found a way to put it back together!

It's like going back to the drawing board and rebuilding it all over again.

He also calculated the power himself.

He believed in himself and his colleagues, but until now... he was still nervous!

Now, Desert can finally say calmly: "Report, the generator set is operating normally!"

"The power grid output is stable!"

"Guo Weiqiang, is there anything abnormal in the load-bearing structure?"

Comrade Guo Weiqiang, who is in charge of the sculpture team, also bears a lot of pressure.

With the offset of gravity, the city's load-bearing structure is no longer the same as before, and some pressure turns into tension. In this case, the city may indeed fall apart.

As a rare person who can understand the "Strong Glyph", he also has a heavy responsibility and is thinking of ways to strengthen the city every day.

"The current main structure, no problem!"

Lu Yuan let out a sigh of relief.

But he knew that the matter was not over yet. When the city was flying, he had to find a way to land. If he couldn't land safely, it would always be unsuccessful.

He calmly gave orders: "I order each team to inspect the city's conditions and check whether there are any structural breaks."

"The Sky City officially flew for two days, and two days later, it officially landed."

Instructions were sent out in an orderly manner and passed to various working groups.

…

…

Two days passed quickly.

After the initial trial flight, the city slowly descended from an altitude of 20,000 meters.

With a soft "boom" sound, the Sky City landed around the village, once again stirring up overwhelming dust.

In fact, after the anti-gravity system is turned on, it has to be "half-open" all the time.

Because there is very little land that can carry 160 million tons of mass at once.

In such a large city, if the pressure is placed directly on the ground, landslides and earthquakes are likely to occur.

Therefore, reducing urban gravity and allowing the ground to carry it is a very complex but important link.

The larger the city, the more difficult it is to regulate energy demand.

Fortunately, mankind has the legacy of green civilization, and the control of gravity has always been done by the green paradise.

However, in the long term, if you want to build a larger new city, you must understand the specific principles and add new energy sources.
