Academy City Temperature Control

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

...

Academy City is exceptionally peaceful today. There are no Gundam robots spraying into the sky, and there are not many human-on-human violence incidents.

The people in the ANBU stronghold were divided into two groups. Senior Bu Shu and Feibuli stayed behind to prepare to awaken Jenny, who was facing loss of control over her abilities.

In order to prevent accidents from happening, Misaka-senpai came up with the idea of ​​intercepting missiles.

"Rescuing Jenny from the out-of-control system requires your help, Fibri."

"Febri and Jenny are almost the same individuals, and your brain waves are the same. I will synchronize your and Jenny's brain waves, Febri, and Febri must try to wake Jenny up."

In the stronghold, Bu Shu Dixin knelt down and rubbed Feibuli's head, encouraging him with a hint of expectation.

It is similar to the Misaka Network between the Misaka sisters, except that Fibri and the others are not power generators and cannot convert brain waves into electronic signals, but Fusu Toshin can use instruments to do this.

"Trust."

After licking the lollipop on his hand, Febri tilted his head and tried to understand.

"I understand, Feibuli will wake up my sister."

Narrowing his eyes, Feibli smiled sweetly.

While waking up Jenny, Misaka-senpai quickly walked through the streets of the [-]th School District.

"The calculation of how to intercept the missile has been completed, and Misaka began to put computing power into the trajectory of the missile."

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

"According to the current conditions, there is only one way to intercept missiles, and that is to use ultra-powerful railguns to destroy missiles in orbit."

Misaka-senpai gritted her teeth and suddenly sped up her pace.

Just like a surface-to-air missile, find the trajectory, capture the target, and hit it accurately.

If you want to rise to an altitude of [-] meters and then fire a super-powerful railgun, you need to transport a railgun shell of sufficient size and the railgun itself to high altitude.

Because the size of the theoretically required cannonballs has exceeded Shirai-san's limit, and a certain electromagnetic gun is required, Shirai-san's space movement has no use.

Apart from Natsume-san, the only one who can do this is Mitsuko-san after marriage.

"But according to Sister Misaka's calculations, it is difficult to find iron products suitable for post-marriage abilities, and ordinary iron products cannot withstand at least thousands of air bursts."

"And even if it is found, it will no longer be usable as a qualified artillery shell by the time it reaches an altitude of [-] meters."

Misaka-senpai has been thinking a lot in her head and has already made a decision in her heart.

So, now we can only rely on Natsume-san, and use Natsume-san's ability to send the cannonball and himself into the stratosphere at an altitude of [-] meters.

An altitude of [-] meters is nothing to the entire atmosphere. The outermost layer of the atmosphere can reach a distance of [-] kilometers from the ground, but at [-] meters, basically only the most advanced aircraft can set foot in it.

Do you have to rely on Natsume-san again? It feels really familiar.

"So that's it. I have no objection."

"However, I have never been to an altitude of [-] meters. When I am bored, I want to go there, but I always return after a few thousand meters."

Natsume Sonoko held her chin and thought, muttering to herself, but then her body collapsed together with Shirai-san's.

Before he could continue to say anything, the scene in his eyes became fragmented, and the frequency of movement was too fast, which forced a certain ball head to quiet down.

The two people seemed to be blurry phantoms under the movement of space, and their positions were constantly changing.

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

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

Natsume Sonoko was suddenly confused, but she turned around and saw the steel locomotive used as an amusement facility in the corner of the park.

And near the steel locomotive, the senior students after marriage and Uiharu were all there.

"This big toy must be enough."

After getting married, the senior sister put the folding fan in front of her face, and a middle-aged office worker in a suit and tie stood beside her and said something.

"Natsume-san, you're here. This is the most suitable thing to use as a cannonball nearby."

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

"General locomotives weigh more than a hundred tons, but this locomotive is only used as an amusement ride, and its weight is less than half of the ordinary one, only about fifty tons."

Uiharu explained.

"Fifty tons, that should be fine."

Natsume Sonoko was slightly startled. She had never brought such a large solid substance with her before.

Although it sounds heavy, it is far inferior to the building that Accelerator waved. Even the rain cloud that Natsume lifted before was far more heavy than this.

After walking to the locomotive and looking at it carefully for a while, Natsume-san suddenly lifted it up with his hand. It was motionless as expected. The first attempt to pull it backwards failed.

But then violent wind and waves swept around quickly, and Ye Zi kept making circles in mid-air. Just when he was about to pull the locomotive up from the ground, he suddenly thought that this locomotive was still someone else's property.

"It's done, I have bought this locomotive."

Hearing the voice of the married senior sister, Natsume-san suddenly exerted force, and the locomotive slowly floated with soil and plant roots.

Chapter 226 Working at heights

The air was mixed with the fragrance of rust and earth. As the locomotive lifted off the ground, a moderate vibration was caused within a few dozen meters around it.

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

"It looks like the train is actually moving."

Affected by the wind and waves, Chuchun couldn't help but take a few steps back, and his eyes were drawn to the front of the car.

Following Uiharu's line of sight, Natsume-san was already standing on the front of the car at some point, waving to the ground.

Less than an hour after the ANBU missile was launched, all preparations were almost completed.

The railgun shells are already in place, the railgun is in place, and the humanoid transport vehicle is in place.

With a look of determination (sluggishness) on her face, Natsume Sonoko was sitting on the white preparation mat for her final rest.

Being exposed to the sun, the clothes that were originally made wet on purpose slowly dried over time. It turned out that Natsume-san's move was meaningless at all.

Although there was no peculiar smell and it still smelled delicious, Natsume-san still felt uncomfortable all over and was ready to take a good shower after finishing the work.

Thinking of some insignificant things, Natsume Sonoko turned her head and looked at the people who were still busy.

It's the married seniors and the others.

"After marriage, classmates, the expenses this time will be borne by the Disciplinary Committee, and the funds you advance will be transferred to your card later."

Not far away, Senior Sister Gufa was chatting with Senior Sister After Marriage. Seeing that Senior Sister after Marriage didn't seem too concerned about it.

"No need, I will be very satisfied if I can do something for everyone."

After getting married, the senior sister showed a hint of the dignity of a lady, raised her head slightly, and covered the front of her face with the unfolded folding fan.

"Natsume-san, here you go."

Someone tapped her on the shoulder, and Natsume Sonoko, who was listening to others chatting, suddenly came back to her senses and found that Misaka-senpai had arrived near her.

"Seaweed rice balls?"

Natsume-san stretched out his hand to catch it, and then asked with some confusion.

"I bought it from Saten-san. It can replenish some energy. After all, Natsume-san will be working very hard for a while."

Misaka-senpai's face was calm, with a smile on her lips, and she sat on the cleaning robot like Natsume-san.

At this time, the others were either cleaning debris from the railgun shells or contacting Academy City officials. The two of them were the most leisurely, and their only task was to have a good rest.

"It's okay. Everyone thinks it will be very hard for me, but in fact it's not that tiring."

The relevant formulas have been simplified many times and have reached a handy level.To achieve similar effects, Natsume-san needs to expend far less computing power than espers of the same system.

Natsume-san tore open the biodegradable plastic film wrapped on the seaweed rice ball and took a sharp bite.

It's not even time for dinner yet, so it's just snack time.When it comes to eating, Natsume-san has never been behind others.

The faint taste of seaweed and the fragrance of rice fill the mouth and tongue, and I also ate a shrimp inside. The simple taste always makes people feel happy.

Although it is not my favorite sweets, it tastes pretty good. Natsume-san gave the rice ball a six out of ten.

A certain meatball head was about to finish the rice ball when Misaka-senpai's cell phone suddenly vibrated.

"The trajectory of the missile has been calculated."

Clenching her fists, Misaka-senpai couldn't help but get excited.

"Are they 'sisters'?"

Natsume-san's mouth was full of rice balls, and he hesitated while chewing.

If Misaka-senpai could find any high-performance computer, it would probably be with the help of her 'sisters'.

"Yes, it's thanks to them this time."

Misaka-senpai nodded and said.

"Now that we know the orbital position, Natsume-san, we have to prepare to go."

Misaka-senpai took a deep breath and jumped off the robot.

"Hey, wait a moment."

Natsume Sonoko was biting a rice ball as she spoke, almost choking because she spoke too hastily.

After a while, Natsume Sonoko threw the plastic film in her hand into the belly of the cleaning robot, and Natsume Sonoko hurriedly followed.

...

No safety seats, no oxygen masks.

Natsume Sonoko and Misaka-senpai stood on the locomotive with a carefree attitude, gradually looking at the ground getting farther and farther away from them, until people and scenery turned into black spots.

The temperature of the environment becomes lower and lower as the altitude increases, and the air becomes thinner. Even the human skin cannot help but bulge slightly because the surrounding pressure has become very small.

However, a certain ace pilot was already familiar with it. The invisible air barrier not only protected them from being disturbed by outside airflow, but also solved these problems.

If it weren't for something important, it would really be like a casual trip.

The locomotive passed through the clouds, like a sharp sword thrust into the sky, surrounded by thick clouds.

Woo woo woo.

From time to time, the whistle would sound, and Natsume-san and the others were moving quickly in the air.

The locomotive, which was originally used as an amusement ride, may never have imagined that one day it would be possible to go up to the sky to see it.

A huge flow of air surged behind the locomotive, and the scenery around it moved quickly behind it.

Ordinary updrafts cannot provide much power, so this time Natsume-san used the legendary jet flight.

The engine of a general jet aircraft collects the gases produced when fuel is burned, and then uses the reaction force of the gases under high-speed injection to provide power.

Natsume-san, on the other hand, used her abilities to achieve an effect similar to that of an engine.

Jet flight has great prospects, and there are many aircraft in the world that use this method to reach supersonic speeds.

But obviously Natsume-san is not yet at that level. In addition, the weight of the locomotive is not light, and the current speed cannot even reach high subsonic speed, which is 0.8 to 0.9 times the speed of sound.

But even so, Natsume-san's speed remains at 200 meters per second, and it is expected to reach an altitude of 3 meters in about [-] minutes.

In order to maintain this high speed, Natsume-san also expended a lot of energy, and her breathing became a little rapid.

The locomotive broke through the thick clouds and rushed into the stratosphere. It seemed that it was suddenly enlightened, and the originally white scene finally became clear and clean.

The surrounding clouds became thinner and thinner, the field of vision became wider and wider, and the sky finally became blue.

There is basically not much oxygen here. Fortunately, Natsume-san still carries a few cubic meters of oxygen stock with him.

Chapter 227 Explosion

As the altitude gets higher and higher, everything here becomes unfamiliar, as if we have arrived in a new world.

Because the surrounding environment is constantly changing, in order to adapt to this change, even Natsume-san's flight formula needs to make some necessary adjustments.

This is the first time Natsume has broken through the troposphere on the surface and reached the stratosphere, which is at least [-] meters above the surface. The biggest change is that the air here has begun to become very thin.
