Temperature Control in Academy City

The chain reaction will directly affect the spread of AIM in all areas of Academy City.

It has some similarities to the 'disorderly development' that has occurred before, but it is more harmful.

Because at that time it was not a so-called earthquake, but a giant explosive dropped inside the Academy City, which could blow the Academy City up to the sky.

As the command was input, a certain engineering machine placed in the geostationary satellite orbit 35,000 kilometers above the ground launched a missile loaded with a conductor at a speed of seven kilometers per second.

"The only way to stop it now is to kill 'Jenny'."

At this time, several researchers looked at each other and walked towards the culture tank containing "Jenny".

Butsuko Toshinori, who was standing by, tried to stop him but was pushed to the ground.

Their steps finally stopped because a panting railgun blocked their way.

"Tell me, what was that final procedure?"

Sweat soaked Tokiwadai's school uniform, and Misaka-senpai raised her head and looked directly at everyone.

Phibrey behind him opened his eyes wide and looked curiously at Jenny sleeping in the culture tank.

"Oune-chan~~"

Sucking on a lollipop, Phibbery waved softly at the culture tank.

"Di Xin."

After a while, Phoebe turned her head again and stared blankly at the cloth bundle on the ground.

...

"Missiles being fired towards Academy City?"

"how so."

A flurry of chatter could be heard all around. Ever since a certain railgun successfully captured this stronghold, all the Anbu personnel had been brought under control.

"Misaka-senpai, I have roughly understood the situation. Give me the properties of the missiles and the trajectory data, and I will try to find a solution."

On the computer screen of the Anbu organization's control console, Hatsuharu's video frame appeared on it, and new people who were successfully contacted continued to join nearby.

Natsume-san and Shirai-san were on their way to the base, but they received a video request from Misaka-san and had to find a place to stop.

"So that's it."

Natsume Sonoko was a little stuck, and her memory of A Certain Scientific Railgun Part 2 was finally complete.

But at this point, these memories are no longer of any use.

"According to the intelligence we have, when it reaches a height of about 30,000 meters above the ground, the missile will release 5,000 small warheads, and it will be impossible to stop it at that time."

Joining the conversation, Butsuko Toshinori spoke with a hint of certainty in his tone.

"Now we can only try to stop the missile from landing, or get Jenny out of the situation where her abilities are out of control."

Butsuko Toshin took a deep breath.

She had no way to stop the missile from falling, so she could only try to wake Jenny up and prevent her ability from getting out of control.

"If it's 30,000 meters, I should be able to get up there, as long as I get some explosives..."

The scene changed, and Shirai-san squeezed in front of Natsume Sonoko's phone and suddenly spoke.

"Let's not talk about whether Shirai-san can reach an altitude of 30,000 meters in his current state. At the high speed of the missile, let alone installing explosives, it's even a question whether Shirai-san can get close."

Natsume Sonoko on the side tilted her head and said bluntly.

The missile would generate scorching heat when moving at high speed, and she was basically the only one who could barely withstand it.

But there is also a big problem.

Seven kilometers per second is dozens of times the speed of sound. Even if the atmosphere can continue to slow down its speed, the earth's gravity still makes its speed continue to increase.

At this exaggerated speed, Natsume has no confidence in stopping it.

In addition, the material of the missile can even withstand friction in the atmosphere, which is very unfriendly to mages of Natsume's school.

Natsume is unable to deal with Sogiita Gunha, who is only twice as fast as the speed of sound and wears a flesh-armored body. He is just as much of a monster as the white-haired guy Accelerator.

"No, the Disciplinary Committee's computer system alone cannot calculate a response in such a short time. It can't even calculate the trajectory of the missile in time."

The girl with the flower on her head suddenly reacted at this moment, and even the computing power of the computer in her hand was taken into account.

If you want to complete a series of calculations in a very short time, the required instantaneous computing power must be at least one-third of the normal computing power of the tree diagram designer.

"But if we want to borrow a computer with enough computing power, it's too late now." Student Saten on the other side said unwillingly.

"I have an idea."

Misaka-senpai suddenly said, hastily pulling out her phone to contact someone.

The brain waves of Misaka sisters are converted into electronic signals, constructing an omnipresent Misaka network in the atmosphere.

The brains of more than ten thousand level 2 ability users were combined, and the quantitative change led to a qualitative change, turning into a giant computer with an effect similar to that of a tree diagram designer.

After hesitating for a moment, Misaka-senpai dialed the number, and the person who answered the phone was Misaka No. 9982, who had just completed cell adjustment.

"No problem, it looks like it's finally my turn. Misaka puts on the Quata mask and prepares to save the world."

Standing on the busy street, a strange girl wearing goggles and a quater mask on her head said so.

Chapter 225: Yuanzi pulls out the locomotive

Is it the junior high school students' turn to save Academy City this time?

Natsume Sonoko couldn't help but look at the sky, which was still as clear and bright as before. Shirai, who was beside her, was as anxious as an ant on a hot pot, not knowing what it meant to be fearless in the face of danger, which made people shake their heads and sigh.

The crisis before him seemed like it could come at any moment, but Natsume didn't feel very nervous.

No matter how you think about it, missiles of this magnitude are well within the Academy City's defense range, and anti-aircraft missiles may have already been aimed at them.

Although the speed of seven kilometers per second is amazing, considering the distance is thirty-five thousand kilometers, there is actually still a full hour, which is more than enough time for Academy City to react.

Having just experienced the hearty massacre of the Six Feathers, Natsume suddenly had a mysterious confidence in the technology of Academy City.

It's just a common little thing.

"Shirai-san, don't be too nervous. There will be no problem."

Natsume Sonoko patted Shirai-san's shoulder and couldn't help but comfort this senior member of the Discipline Committee.

Speaking of which, it was this senior who helped me join the Disciplinary Committee. Now that I think about it, I still feel that his motives were not pure.

"There's news."

Shirai-san said a little loudly, attracting the attention of others.

...

Today's Academy City is exceptionally peaceful. There are no Gundam robots spewing into the sky, and there are not many incidents of violence between humans.

The people in the Anbu base were divided into two groups. Senior Butsu and Febree stayed behind to prepare to wake up Jenny who was facing the risk of losing control of her abilities.

In order to prevent accidents from happening, Senior Misaka came up with the idea of ​​intercepting the missile.

"To rescue Jenny from the out-of-control system, I need your help, Phibre."

"Phibre and Jenny are almost the same individual. Your brain waves are the same. I will let Phibre synchronize your brain waves with Jenny. Phibre must try to wake Jenny up."

In the stronghold, Butsuko Toshin squatted down and rubbed Phoebe's head, encouraging her with a hint of expectation.

It is similar to the Misaka Network between the Misaka sisters, except that Phoebe and the others are not users of power generation and cannot convert brain waves into electronic signals, but Toshinori Butsuka can do this using instruments.

"Di Xin."

Licking the lollipop in her hand, Phibre tilted her head and tried to understand.

"I see. Phibre will wake up my sister."

Narrowing her eyes, Phibre smiled sweetly.

While waking up Jenny, Misaka-senpai quickly walked through the streets of District 7.

"The method to intercept the missile has been calculated. Misaka has begun to put computing power into the trajectory of the missile."

The voice of Misaka No. 9982 came from Misaka-senpai's phone again.

"Under current conditions, there is only one way to stop a missile, and that is to use a super-powerful railgun to destroy the missile in orbit."

Senior Misaka gritted her teeth and suddenly quickened her pace.

Just like a surface-to-air missile does, it finds the track, captures the target, and then hits it accurately.

If you want to rise to an altitude of 30,000 meters and then fire a super-powerful electromagnetic cannon, you need to transport a super-electromagnetic cannon shell of a sufficient size and the super-electromagnetic cannon itself to a high altitude.

Because the theoretically required shell size has exceeded Shirai's limit, and he also has to bring a certain railgun, Shirai's spatial movement is useless.

The only one who can do this besides Natsume-san is Mitsuko-san after marriage.

"But according to Misaka's calculations, it is difficult to find iron products that are suitable for the power after marriage, and ordinary iron products cannot withstand at least thousands of air bursts."

"And even if we find it, it will no longer be usable as a qualified artillery shell when it reaches an altitude of 30,000 meters."

Senior Misaka has been thinking a lot in her head and has already made up her mind.

So, now I can only rely on Natsume-san. With the help of Natsume-san's ability, I can send the shells and myself into the stratosphere 30,000 meters high.

An altitude of 30,000 meters is nothing for the entire atmosphere. The outermost layer of the atmosphere can reach a distance of 1,000 kilometers from the ground, but at 30,000 meters only the most advanced aircraft can reach it.

Do I have to rely on Natsume-san again? It feels so familiar.

"I see. I have no objection to that."

"But I have never been to an altitude of 30,000 meters. I would like to go and see it when I am bored, but I always return after a few thousand meters."

Natsume Sonoko held her chin in thought, muttering something to herself, but then she and Shirai-san shattered together.

Before he could say anything else, the scene in his eyes became fragmented, and the frequency of movement was too fast, which forced the guy with the bun to be quiet.

As the space moved, the two people seemed like blurry phantoms, their positions constantly changing.

When Shirai finally stopped, they had already arrived at a theme park in the seventh school district.

"Shirai-san, what are we doing here?"

Natsume Sonoko was suddenly a little confused, but when she turned around, she saw a steel locomotive that served as an amusement facility in the corner of the park.

And near the steel locomotive, Senior Sister and Hatsuharu were all there.

"Surely this big toy will be enough."

The married senior student put the folding fan in front of her cheek. A middle-aged office worker in a suit and tie stood beside her and said something.

"You're here, Natsume-san. This is the most suitable thing around to be used as a shell."

Uiharu breathed a sigh of relief and pointed at the locomotive.

"A normal locomotive weighs more than a hundred tons, but this locomotive is just an amusement ride, so it weighs less than half of the normal one, only about fifty tons."

Uiharu explained.

"Fifty tons, that should be enough."

Natsume Sonoko was slightly stunned, as she had never carried such a large solid object before.

Although it sounds heavy, it is far less than the building that Accelerator was waving. Even the rain cloud that Natsume-san lifted before was much heavier than this.

After walking up to the locomotive and examining it carefully for a while, Natsume suddenly tried to lift it up with his hand, but it did not move at all, just as he had imagined. The first attempt to pull it out had failed.

But then the violent wind and waves quickly swept around, and the leaf kept circling in the air. Just when he was about to pull the locomotive off the ground, he suddenly remembered that the locomotive was someone else's property.

"It's done. I've already bought this locomotive."

Hearing the voice of the married senior in her ears, Natsume-san exerted force in a trance, and the locomotive slowly floated up with the soil and plant roots.

Chapter 226 High-altitude Operations

The air was mixed with the fragrance of rust and soil. As the locomotive left the ground, a not-so-small vibration was caused in the area dozens of meters around it.

A large amount of air filled the interior of the locomotive, and a translucent air column emerged from the steel chimney on the top of the train, and a strong and majestic whistle sounded.
