Chapter 236: City in the Sky—Take Off!

The two intense months passed quietly.

The day when the city in the sky would rise finally came! It was an ordinary day filled with a sandstorm.

At daybreak, everyone was awakened by the emergency bell.

The hot sand blowing on my face cannot extinguish the fanatical heart.

The power system of the Sky City is actually quite average, and the electricity provided by humans is seriously insufficient, resulting in the city's extremely slow flying speed.

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

Lu Yuan got up early, before four o'clock. He was in a very good mood and wore an exquisite dress left by the Green Civilization. It was a bit like a tuxedo, and the exquisite leaf pattern brought a sense of gorgeousness.

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

She also wore a pink poppy flower on her head, which made her look playful and cute.

"You're not going to show up in public, so why do you dress up so beautifully?" Lu Yuan looked at her for several times and found the pretty girl to be pleasing to the eye.

"This scene must be recorded in the Green Paradise to educate future generations!" Conch jumped up and down, holding a small flower and putting it on Lu Yuan's chest, smiling, "Commander-in-chief, I hope the city won't fall!"

Lu Yuan immediately stretched out his dirty hands and ruffled her hair into a ball, then ran away happily amid the girl's angry rage.

Five o'clock in the morning.

The various working groups have already had breakfast in the cafeteria.

Today the cafeteria lady’s hands no longer shook and the food portions were very generous.

Everyone was talking and laughing, and the air was filled with a warm sense of anticipation.

At 5:30 in the morning, the main force gathered, and both the old and the young put on their best clothes.

Lu Yuan said loudly: "Friends, today is the day to test the results of our 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 extend to every corner of the city, blooming green leaves one after another and emitting a faint green light.

The entire Sky City’s heritage is piled up in the inner ring.

Whether useful or useless, they were piled up in the warehouses.

Even some large objects cannot be stacked at all and have to be left in the open air.

"Oil reserves, totaling 1.68 million cubic meters."

"The power unit is operating normally!"

"The total metal storage in metal warehouses is 21.82 million tons."

Lu Yuan counted his assets and found that they were truly filled to the brim, with no room for any more.

The time to test the final results has come. Everyone has been working hard for this day for a year and six months, but whether it can succeed is still an unknown...

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

"Let Shakaner lead the team, and don't leave anyone behind!"

"Understood!" Shakaner saluted and rode on the giant insect "Drainer".

More than a thousand villagers sat on the back of each "drainer", and they marched towards the village in a mighty procession.

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.

"You three should keep an eye on it to avoid any accidents."

"I have the ability to protect myself."

The three king insects bowed slightly: "Yes!"

Flap your wings and fly away.

The "Drainer" moved very quickly in the desert. In less than half an hour, it had covered more than 30 kilometers.

A dark crowd of people stood on the back of the insect, staring eagerly towards the horizon.

People are nervous but full of expectations.

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

"Countdown, ten seconds..."

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

As the countdown came to an end, this city that had sunk for four thousand years was completely revived at this moment! "Boom!" The sky collapsed and the earth shook.

Huge amounts of dust flew up, forming a huge air wave that advanced in all directions like a tsunami.

People heard intermittent conversations between various working groups on the intercom.

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

"The poppy tree is relatively stable, and the energy circuit system is functioning normally."

"The Pandora Crystal Anti-Gravity System has been officially activated. The gravity of the rock is being offset... There is a small amount of abnormal suspension phenomenon, and the speed of ascent is somewhat abnormal."

People's hearts were in a knot. They didn't understand what "abnormal suspension" meant, but their hearts were in a knot.

…

Lu Yuan and others who were in the center of the city were also sweating coldly. It might be because the energy output was a bit high. The city was rising too fast, like a flying bird. Many people fell directly to the ground!

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

After the gravity of the rock is offset, the city will be lifted up by the atmospheric pressure and float like a balloon. (The non-rock part cannot be offset.) At this time, it is required to retain a little gravity so that the city's gravity and atmospheric buoyancy remain relatively stable.

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

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

“The city remains stable at the moment.”

I don’t know if it was because of nervousness or excitement, but the crowd was silent, with their eyes wide open.

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

"I see 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 saw that city.

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

The rest of the people also held their breath, not blinking, and cheers and lively discussions mixed together.

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

This was a sunrise that was unprecedented in history! ! As the red sun slowly rose, the city in the sky also rose along with it, bathing in the vast sunlight.

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

More and more people saw the rising sky city, and suddenly tears of happiness flowed from their eyes! They did it, they... could leave this desert.

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

Some people’s joy came from escaping and ascending to heaven. They didn’t actually participate much, they were just shocked… It was really magical that a stone city could 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, they realize that everything was created from nothing and obtained through labor.

They really paid a lot for this operation.

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

This kind of emotion, this kind of joy, is not because of the improved living conditions or the escape from the threat of death, but the emotion of having an ideal realized.

They were 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 was standing on the highest point of the poppy tree, overlooking the vast desert, feeling a sense of heroism.

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

This scene is truly breathtaking! In the vast desert, smoke rises straight up, the sun rises round in the endless sky, and the coarse sand is trampled underfoot. 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 unlikely that such a huge thing could be built using purely physical technology.

But Weixin Technology has done it!

As the gravity of the rock disappeared, the city continued to rise.

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

According to the information from the Green Civilization, there is strong idealistic interference above the atmosphere, and the Pandora crystal may fail, causing the anti-gravity system to lose control; and if the altitude is too low, there is a possibility of being attacked by monsters.

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

"I order the altitude to be stabilized at 20,000 meters."

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

[Look at how proud you are. Fortunately, you are dressed beautifully and with a sense of ceremony! ] As the controller of the Poppy Tree, Conch took a break from his busy schedule and sent a telepathic message.

"Such a big treasure has risen, and we can't be complacent."

“Boom!”

Several giant propellers began to rotate, propelling the city - this thing was like a wind turbine, with the blades alone being hundreds of meters long.

Its maintenance is very complicated, and currently only a few owners with "artisan talent" have repaired it.

Lu Yuan was very worried that the propellers would fall apart midway.

The giant propeller roared and creaked, but at least it was moving, giving a sense of steampunk aesthetic.

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

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

Well, this speed is indeed very slow.

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

If he wanted to fly faster, he would need some glyphs to reduce air friction, a jet propulsion system, and other miscellaneous things - of course, this would be another huge project, and Lu Yuan didn't have the time or energy to do it for the time being.

"Shamo, how is it over there? Can the generator handle it?!" Lu Yuan asked on the intercom.

The balance of the sky city and the operation of the propellers were projects supervised by Lao Mao himself, and they were considered stable.

The power stations and power networks are personally supervised by the current first wise man, the "super thinker", Sha Mo.

After all, he had only studied for two or three years. Even though he was smart, everyone was still worried about his ability...

Yes, even Sha Mo himself was worried that he might not be able to complete the task!

But there's nothing I can do.

There is no talent at all now. There is only one smart old cat and one conch. They cannot have multiple jobs. He can only force them to do something else! "I'm checking the parameters of the machine!"

He clenched his fists, his entire palms had turned blue and purple, and thinking back on the past days, he sighed in his heart.

He and his team repaired the generator because the original equipment was badly damaged and had to be disassembled and repaired, and then reassembled! It was like going back to the drawing board to rebuild it.

He also calculated the power himself.

He believes in himself and his colleagues, but even now... he's still nervous!

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

"Grid output power is stable!"

"Guo Weiqiang, is there anything wrong with the load-bearing structure?"

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

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

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

“There is no problem with the current main structure!”

Lu Yuan let out a sigh of relief.

But he knew that things were not over yet. The city was flying, so he had to find a way to land. If he couldn't land safely, it would be a failure.

He calmly gave orders: "I order all teams to inspect the city and check for any structural fractures."

"The Sky City will officially fly for two days, and after two days, it will officially land."

Instructions were sent out in an orderly manner and delivered to each working group.

…

…

Two days passed quickly.

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

With a slight "boom" sound, the city in the sky landed near the village, once again raising a cloud of dust.

In fact, once the anti-gravity system is turned on, it has to be kept "half-open" at all times.

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

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

Therefore, reducing the gravity of the city and allowing the ground to bear the weight is a very complex but important step.

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

Fortunately, humans have the heritage of green civilization, and the regulation of gravity has always been accomplished by green paradise.

However, in the long run, if we want to build larger new cities, we must understand the specific principles and incorporate new energy sources.
