Surface.

Li Ningning bit her lip, craned her neck, and looked up at the silent and bright Sky City, supported by thousands of blue "moons."

She had been looking up like this for a long time.

Her neck was sore and tired.

But everyone was like her, reluctant to lower their heads, not even for a second...

Two hours ago, they saw it clearly from the ground.

In the darkness, three white dots jumped from a height of 20,000 meters, diving down towards the Rhine Sky City, which had been floating for over 200 years.

At that moment, many people couldn't bear to close their eyes, fearing to see three blood-red lasers evaporate them.

However!

Contrary to everyone's expectations!

The three falling from high altitude descended in a straight line, diving straight down, with no sign of anti-aircraft lasers!

At first, everyone thought they hadn't reached the required altitude.

But as the falling height decreased, and they were almost out of sight due to the perspective, cheers erupted:

"Suc...successful! They broke through! They found a gap in the air defense network! That young man was right!"

"I can't believe it, I didn't expect that young man to be right. How did he know all this? And so accurately, all three of them are unharmed!"

"Miracle! This is an unprecedented miracle! Since Mrs. Li Cheng accidentally jumped into the gap in the air defense network more than ten years ago, no one else has ever entered! And this time, three people went in together, increasing the probability of finding the medicine!"

"This is all thanks to the spirits of those heroes in heaven, our hard days are finally over..."

...

But.

As time passed.

They used telescopes to search every corner of Sky City, but found nothing unusual.

Everything was calm.

As if nothing had happened.

Although everyone understood that it would take some time to find the medicine and then parachute down.

But...they couldn't help but worry about them.

Remembering Li Ningning's mother, who also jumped into Sky City but ultimately failed to come down, they assumed she must have died in the city.

Everyone's mood became increasingly low and hopeless.

Er Zhuzi clenched his sweaty hands, swallowed, massaged his sore neck, and looked at the sky:

"Ge Lian and A Zhuang, they won't... won't something happen to them, right? Can they really succeed?"

"I think they can." San Pang nodded with firm eyes.

"I think they can too." Li Ningning stared at the sky, decisively.

She turned her head and looked at Er Zhuzi:

"Since Lin Xian was able to successfully lead them into the gap in the air defense network, it means that all the information Lin Xian said is correct; Lin Xian said very clearly that the security in Rhine Sky City is very lax, as long as we get in, no one will care about us. So... they will definitely succeed."

Li Ningning clenched her fists, biting her lip:

"They will, I believe in Lin Xian."

Alas...

Er Zhuzi sighed and shook his head:

"Ningning, you're still too naive. This is also the first time you've met Lin Xian, how can you trust him so much? Don't forget, he took Ge Lian and A Zhuang up there with conditions, with his own purpose, he said they must go to the museum with him first."

"I do trust him."

Li Ningning looked at Er Zhuzi, her eyes unwavering:

"Lin Xian, he... is definitely a man of his word, a man who keeps his promises."

Boom!!!!!!!!!!!!

Suddenly.

A loud noise came from the sky!

Everyone heard the sound and looked up, but then squinted their eyes—

They saw that the nuclear fusion engine in the very center of the Rhine Sky City exploded!

The violent light produced by the explosion lit up the entire night sky! As bright as day!

Just when they didn't have time to be shocked...

Boom!!! Boom!!! Boom!!! Boom!!!

The four nuclear fusion engines next to it also exploded one after another! Four small suns of blue light flashed in the night sky, and the mechanical debris produced by the explosion scattered to the horizon, turning into sparkling shooting stars.

Li Ningning widened her eyes, unable to believe all this.

Rhine Sky City...

This behemoth that had been floating in the sky for 200 years, it was always so stable, always so majestic.

It was like an unchanging god, hanging in the sky, unmoved by the world.

But now, it exploded!

Amid everyone's exclamations of shock... dozens more nuclear fusion engines exploded, one after another, blooming brilliant blue fireworks above 2000 meters!

Then, like dominoes, the explosions linked together, centered on the first exploded nuclear fusion engine, and quickly spread outward!

Dozens,

Hundreds,

Thousands!

Thousands of magnificent nuclear fusion fireworks dyed the entire sky a crystal blue!

Thousands of "moons" hanging in the night sky, at this moment, all turned into "suns," and the blue fireworks covering the sky were reflected in people's pupils, like shattered galaxies, sparkling glaze...

"Sister! What beautiful fireworks!"

At Li Ningning's feet, a little girl with black sores and pus on her face cheered, tugged at Li Ningning's clothes, and laughed and jumped non-stop.

"Mm..."

Li Ningning bent down, picked up the little girl, and together they looked up at the most gorgeous fireworks in the world.

At this moment, Li Ningning understood everything.

She looked at the tip of her right little finger, as if still hooked by that warm big hand, that gentle touch seemed to still exist, hooking her little hand, telling her to blow up this city for her.

"Indeed... so beautiful..."

Li Ningning's voice trembled, forcing a smile.

The thousands of "suns" above her head smiled at her, those were the fireworks Lin Xian set off for her.

This was the only, unique fireworks in the world that belonged to her.

Perhaps some girls would have fireworks set off by their beloved parents to celebrate their birthdays;

Perhaps some girls would watch firework extravaganzas with friends on amusement park nights;

But only she, only this man she met once... was willing to detonate 6000 nuclear fusion engines for a child's innocent words, lighting up the entire sky!

Rumble...

Rumble...

Rumble...

The sound of the explosion came later than the light. Amidst the vibration of their eardrums, people were surprised to find—

The height of Sky City was decreasing!

It was falling!

Oh my god...

That was the Sky City that had been hanging high in the sky for more than 200 years!

That was a god-like existence!

But now, it was slowly falling to the ground!

At this moment...

Except for the hundreds of nuclear fusion engines on the outermost circle of Sky City running at full speed, all 6,000 engines in the middle had been completely exploded.

The thrust was not enough to offset the huge weight of Sky City.

Fall.

Beginning!

Around the surface...

More and more white lights lit up, more and more crowds gathered.

The 6000 nuclear fusion engine explosions in the night sky woke up all the surface residents within hundreds of miles.

They all woke up from their dreams, ran out of their homes, gathered together, and were shocked by the grand occasion of Sky City's fall:

"Oh my god...

Rhine, Rhine Sky City is falling!"

"We're saved! There must be medicine for radiation sickness inside! We're saved!"

"Who... who is the hero who did this?"

Rumble... Rumble... Rumble...

As the height of Sky City's fall continued to decrease.

The sound it brought was getting louder and louder. The huge city, spanning thousands of square kilometers, was much larger than the international metropolis of Donghai City on this ground hundreds of years ago.

It was such a huge Sky City that had been flying for 200 years that ushered in its end today.

More and more crowds gathered on the ground... more and more...

From all directions, hundreds of thousands of people surrounded the landing point of Sky City, holding up lights to welcome this moment that would be recorded in history!

At the same time, the inside of the Rhine Sky City was also in turmoil.

The entire city range suddenly turned into a no-fly zone, and all aircraft were lying motionless on the ground.

The security robots were carrying all kinds of weapons and running towards the edge of the city.

Their target was not the humans below, but the high walls at the edge of Sky City.

Various weapons and ammunition were poured out, and when the Rhine Sky City fell to a height of 800 meters, these walls had all collapsed, and the inside and outside of the city were unobstructed!

Finally...

The huge Sky City was like dark clouds pressing down, and it looked as if it was close at hand.

At this moment, the last circle of nuclear fusion engines on the outermost layer began to operate at ultra-high frequencies, and the blue particle beam sprayed out instantly turned into a dazzling white light!

This was the last struggle of those nuclear fusion engines that had been in service for 200 years. Their last roar allowed the Rhine Sky City to slowly decelerate, allowing it to land on the surface at a slow speed.

600 meters,

400 meters,

200 meters,

50 meters!

The once unreachable Sky City was now close at hand!

The last hundreds of nuclear fusion engines exploded at the same time, and the reaction force turned into the last tens of meters of fall buffer—

Boom!!!!!!!!!!!!!!!

An unprecedented loud noise lasting for dozens of seconds...

Rhine Sky City.

Fell! Hereafter!

Smoke and dust dissipated in the night wind.

Hundreds of thousands of onlookers outside Sky City were dumbfounded.

Falling from this high sky, even if the speed was very slow, the impact was still very large.

But not only did the Rhine Sky City not disintegrate, but not even a single building collapsed!

This not only meant that the material structure was strong enough, but it also confirmed that the central control system of Rhine City was incredibly powerful.

"We're saved!"

Countless suffering surface people, with tears streaming down their faces, ran madly towards Sky City.

"I want to go too! My illness is cured!"

The little girl Li Ningning was holding jumped down and ran away with the crowd.

Li Ningning was still stunned in place, looking at all this in disbelief...

This was a scene she had imagined countless times in her dreams.

At this moment, it became a reality.

Her breathing became rapid.

Not because of fear, not because of excitement, but because in the gradually dissipating smoke... a familiar tall figure slowly walked towards her!

Although she couldn't see his face in the smoke.

But just that shadow, Li Ningning recognized him in an instant!

Lin Xian...

That miraculous man;

That man who hooked fingers with her;

That man who promised to blow up Sky City for her, setting off the most gorgeous fireworks in human history for her.

Before her, he smiled and walked out of the smoke, followed by a garbage can emitting green light.

"Ningning."

Lin Xian stepped forward, rubbed Li Ningning's head, took her small, calloused hand, and placed a soft thing in her palm.

Li Ningning looked down.

It was...

That sachet.

Patched, old, with the word "Peace" embroidered by her mother in the middle.

"Here you go."

Lin Xian curved her small hand and held it, holding the sachet that originally belonged to her:

"This sachet is really effective, thank you."

"No... no..." Li Ningning recovered from the shock and shook her head:

"I clearly, didn't do anything."

"Your bravery will one day bring you good luck." Lin Xian smiled:

"In any era, this world needs brave and fearless girls like you."

Suddenly.

From the smoke behind, came Ge Lian Mao's shout:

"Ningning! Ningning! Come here! Look who this is!!"

Hearing the sound, everyone looked towards the smoke that was about to be blown away by the night wind.

They saw Ge Lian Mao and A Zhuang running towards this side quickly, and beside them, there was also a mature and graceful female figure!

"Sister! Sister-in-law!!!"

Er Zhuzi burst into tears and rushed into the smoke like a mad dog!

Sister-in-law?

Lin Xian turned his head to look, and could only see a vague shadow in the smoke... This Er Zhuzi really has a Sharingan? He can see who it is clearly?

And when that charming but dusty woman walked out of the smoke, Li Ningning instantly widened her eyes and held her breath.

She wasn't sure...

Wasn't sure if that was it.

But, there was a inexplicable sense of familiarity! A sense of closeness!

"Mom—"

Li Ningning, who was strong, brave, and never shed tears, burst into tears that had been suppressed for more than ten years at this moment, blurring her eyes and wetting her sleeves.

She didn't bother to wipe her tears, ran forward and threw herself into her mother's arms, wailing loudly.

She cried so loudly.

So loudly that Ge Lian Mao and Da Zhuang couldn't pull her up.

Lin Xian looked at Li Ningning, who was crying out of shape, and couldn't help but feel a little emotional...

Even though he had seen Li Ningning so many times in two dreams.

But this was the first time he had seen Li Ningning crying so weakly.

Ge Lian Mao also said.

Over the years, Li Ningning had never shed a tear.

Even if she secretly practiced parachuting and broke her bones, she gritted her teeth, her lips were bitten, but she didn't cry, didn't even whimper.

She was always so strong.

So unwilling to admit defeat.

But...

No matter how strong a tough guy is, he can't resist the tenderness and warmth in his mother's arms.

In the past, Li Ningning had no place to shed tears.

But now.

She has a mother.

She can cry.

...

Ge Lian Mao told Lin Xian that after they got the medicine and prepared to parachute, they met Li Ningning's mother at the very edge of the square.

She didn't die after successfully parachuting back then.

She also found medicine to treat radiation sickness.

But... she tested it and found that the lower area of ​​this Sky City was also covered by anti-aircraft lasers.

Therefore, jumping into Sky City was a one-way road. Even if you succeeded in getting in and getting the medicine, you couldn't jump down.

But for so many years, she still didn't give up, and tried to find gaps in the air defense network around Sky City every day.

But, this time she wasn't so lucky.

The defense network of Rhine Sky City was perfect, and she realized that the existence of the gap above the statue was not an accident, not an oversight, not luck... but deliberately left for a certain purpose, a certain person.

Over the years, the only belief that supported her to survive in Rhine Sky City was to wait until one day she could find a way to jump down and see her daughter again.

Every night, she would sit in this square, look up at the stars, and expect a second person to jump in.

But for more than ten years, she had not been able to get her wish.

Until today.

...

On a small hill.

Lin Xian sat on a protruding stone, with the garbage can robot VV squatting next to him. The two of them silently watched the Sky City that had fallen to the ground.

"I figured it out."

Lin Xian said softly:

"I figured out what Zhao Yingjun left me in this world."

"What is it?"

The garbage can robot blinked curiously.

"Actually, the answer is obvious."

Lin Xian smiled:

"You see, in this world, history is false, tampered with, without value and meaning."

"And someone is monitoring Zhao Yingjun, so she doesn't dare to easily leave anything useful. She painstakingly went around and left me such a subtle loophole backdoor, so other useful clues, I guess she can't hide or dare not hide."

"In general, this world, this future, is actually a failed future, a future without value and meaning. Of course, I can definitely find a lot of things to get rich, but these things don't mean much to me."

"For a loser, the most valuable things are strength, power, and the means to fight against the enemy. Zhao Yingjun must know these things better than me, so she left me what I need most."

"Oh, what is it, tell me quickly!" The garbage can robot VV impatiently poked Lin Xian's knee with its clip.

"I said it's obvious, can't you realize it?"

Lin Xian turned his head and looked at VV:

"Zhao Yingjun crossed 600 years and left me—"

"It's you."

"Me?" VV pointed at himself with the clip.

"That's right."

Lin Xian nodded:

"You are a super artificial intelligence created by the smartest scientists after hundreds of years of research. Your ability is very strong, but you are limited by the limitations of the underlying code, so you can't leave Rhine City, and many things can't be done. You also said that without these code restrictions, you would be hundreds or thousands of times stronger than you are now."

"The reason why you have these restrictions is definitely because of the interference and secret monitoring of the people in the Genius Club. With this understanding, things become easier. We go to a place where they don't interfere, and even they don't realize that you exist, and delete all the code that restricts you, can't we?"

VV shook his head:

"I still don't understand what you are talking about."

"You are an artificially retarded, you really disappoint me too much." Lin Xian chuckled and patted its head:

"VV, you are a 600-year-old level designed by Zhao Yingjun, and the final gift left to me."

"So, I want to take you..."

"Take you back to 600 years ago!"
