Temperature Control in Academy City

Natsume didn't feel like an outsider at all. Instead, he felt like he was home. When he heard someone ringing the doorbell, he subconsciously scanned the outside for uninvited guests.

He is tall and is accompanied by three little girls.

It feels so familiar, as if I have seen it somewhere before.

Natsume lowered his head and thought for a moment, then a look of sudden realization appeared on his face.

“Why did you ring the doorbell?”

Standing at the door, the red-haired magician's face darkened and the arm holding the cigarette trembled slightly.

"Didn't the master tell me that I should ring the doorbell before entering?"

There was a hint of grievance on the face of the magical girl Jane, as if she had realized that she had done something wrong again.

"Forget it. Remember to protect yourself this time and don't let yourself be killed so easily."

The rune magician named Stiyl turned around and looked around. The walls were covered with various runes that summoned the 'Witch Hunting King'.

At the same time, runes for "dispersing idlers" have been placed in this building and even within a radius of dozens of meters nearby.

The so-called runes to disperse idlers and prevent irrelevant people from approaching the battlefield will make people feel like they don't want to get close to this place for some unknown reason.

But it also has weaknesses. For people who have reasons to pass through, the effect will be greatly reduced, and they can forcibly overcome the psychological suggestion of not wanting to get close.

"Master, I understand. We are well prepared this time."

The three girls nodded at the same time. Each of them had a half-human-high water ball on their head, with enough oxygen reserved in the middle for breathing. It seemed that this was their preparation this time.

"But Master, why don't we wait until they separate before taking action?" The magical girl named Mary seemed very troubled.

"Because we have to leave here tonight."

Putting down the cigarette in his hand, a hint of coldness appeared in his pupils.

The last time was to take Alyssa away, and all the means were very gentle, at least that's what he thought.

However, as an intelligence officer from the Church of Necessary Evil conducted an all-round inspection of the entire cosmic elevator, it was determined that it was a magic circle capable of destroying the northern hemisphere.

The goal of this mission is to kill the core of the magic circle at all costs, that is, the girl named Minghu Alisa.

This is the simplest, most convenient and most effective method, which is the same reason why Kamijou Kaori proposed to kill Conan.

"One of the five elements that built the world, the great flame of the ancestors, that is the light of grace that gave birth to life..."

As a chanting sounded, invisible wind blades pierced through the closed windows in the corridor and attacked the red-haired magician mercilessly.

"Misaka-senpai, someone is coming. It's the person who attacked Naruto-senpai before."

Standing up from the sofa in a hurry, Natsume Sonoko looked at the Discipline Committee 177th Branch with some distress, thinking that she might not see it again after today.

"Kuroko, please."

Misaka-senpai reacted immediately and nodded to Shirai-san behind her.

Without hesitation, Shirai grabbed the closest seniors, Uiharu and Narumori, with both hands, clamped his wheelchair with his feet, and the three of them disappeared from the spot in an instant.

Chapter 277 High Fever Sphere

Under normal circumstances, Natsume's wind blade is at most equivalent to a jet of low-speed gas.

But as long as we use air to create an air pump with internal pressure and reduce the area of ​​the jet outlet, we can make these wind blades have kinetic energy comparable to that of a bullet.

However, the wind blade in this state can easily disintegrate in mid-air, is difficult to control, has a vague range, and is not even as useful as the water knife.

As these wind blades were easily blocked by a flash of fire, the handle of the originally closed door was instantly melted by the high temperature, and all kinds of detection instruments on it were instantly destroyed.

And at the moment of destruction, waves of alarms spread outward.

But it was a little strange that the surroundings were still so quiet, as if everyone had disappeared.

The brief battle in the corridor immediately broke the originally peaceful time.

At this time, Natsume no longer cared about the fact that he was in the Discipline Committee of Branch 177, and immediately activated a battle plan in his mind.

Ever since the last fight with this magician, Natsume found himself at a disadvantage everywhere, so when he was sleeping, he suddenly thought of a way to deal with this person.

Natsume-san looked towards Misaka-senpai again and found that everyone was relatively calm.

Now all we have to do is wait for Shirai-san to come back and leave with Komoe-sensei and Saten-san.

However, Natsume did not intend to retreat. She still wanted to find out why these magicians attacked Senior Minghu. This was very important to them.

I was just discussing these things with Shirai-san, but I didn't expect them to be right in front of me now.

Natsume-san doesn't intend to miss this opportunity, and it seems that Misaka-san is the same.

At this time, outside the building, Natsume disassembled the original air pressure pump and added a large amount of gas to create a huge air pressure cannon outside the building.

What is emitted by this air pressure cannon is not a wind blade, but a large-scale high-speed air shock wave, the instantaneous speed even exceeds the speed of sound.

As long as we continue to increase the pressure of the air pressure cannon, it will be enough to deal with the fire of the fire magician.

You know, the air cannon is also called a blockage clearer, and it is a very useful thing.

No matter how hot the flames emitted by the opponent are, I can blow them away. This is Natsume's current tactic.

I thought a lot about it in my head, and this is what I actually did.

The muzzle of the gun was pointed at several magicians in the corridor through the window, and the glass of the window was shattered by a guy with a bun in the wind blade just now.

It was not Natsume's intention to destroy public property. She just didn't care about the details when fighting.

"Master, look outside the window."

One of the magical girls pulled Stiyl's sleeve, and then he discovered that a transparent sphere emitting high temperature appeared outside the window, and it was gradually glowing.

In order to create a shock wave with sufficient power, a certain guy with a meatball head kept squeezing and compressing the air, and the internal pressure became greater and greater.

As the air became too dense, a large amount of friction inside generated high temperatures, causing the internal air temperature to rise rapidly.

Originally, he just planned to keep squeezing the air to create huge kinetic energy, but now something happened that was beyond Natsume's expectations.

In just a short time, the temperature of the sphere rose to more than one thousand degrees Celsius, far exceeding the temperature control limit of Natsume.

Huge waves of heat flowed into the Discipline Committee Branch 177 through various channels. Combined with the heat map in his head, Natsume immediately realized that there was a big problem.

And because friction can generate electric current, as the internal temperature and pressure increased, Natsume's air cannon suddenly became electric, and a large amount of electric current instantly destroyed the power supply system of the entire building.

All that's left is for the temperature to rise to the plasma temperature and ionize the air into plasma. At that time, the ball will become plasma.

"Rasengan?"

Natsume felt the high-temperature sphere and suddenly started mumbling to himself.

As long as he could transform the squeezing compression into rotational compression, Natsume felt that he could completely make the Rasengan by hand.

"Natsume-san, what happened outside?"

Teacher Xiaomeng and the others have been taken away by the returning Shirai-san, and Senior Misaka breathed a sigh of relief and asked quickly.

"There seems to be something wrong with my formula."

Natsume-san said hesitantly, his face suddenly turning red.

For people of their level, it is very rare for such a big mistake to appear in the formula.

It's obvious that everyone usually gets 100 points in the exams, but if you suddenly get 59 points today, it would be very embarrassing to tell others about it.

Natsume-san can now be considered a person with an idol burden.

"No, there's nothing wrong with the formula. I seem to have calculated too much."

Natsume checked the formula again and found that it was just like his other formulas. The only problem was the number of calculations.

It turns out that the air is concentrated at the same point, and after being compressed with an ultra-high compression rate, a high-temperature sphere is formed through internal friction.

In this way, it indirectly fills the gap that a certain bun-head cannot create ultra-high temperatures.

If you think like this, it's not my mistake at all, but a new trick developed by the genius me.

Thinking of this, Natsume became inexplicably excited.

"Master, what should we do?"

All the heat was blocked by Stiyl, but the other magical girls suddenly became a little confused.

These magical girls are still unable to remain calm in the face of danger, which is much worse than a certain terrible super-powered girl.

"To think that such a move was developed so quickly."

Steele frowned, feeling that things were not simple.

He still remembered the previous battle clearly. Although this lv5 ability was tricky, it did not pose much of a threat to him. What impressed him most was her tracking method.

And now, this high-temperature sphere quickly rose from more than one thousand degrees Celsius to two thousand, and it is still rising. My original suppression of this level 5 has been completely reversed.

What surprised him was that the fireball, which was emitting high temperature, suddenly exploded.

With a violent gas explosion, a large amount of gas was controlled to gush in the opposite direction, but it still destroyed a wall of the small building.

"It's solved. Fortunately, there are no major problems."

He decisively stopped the input of computing power and guided the gas to be released to the outside world. Natsume immediately felt relaxed.

She had a feeling that if she didn't stop, something serious might happen.

Although the high-temperature sphere in front of him is still his ability, Natsume does not intend to use this uncertain move casually until it is perfected.

Chapter 278 Barrier

A large hole collapsed in the wall, and cracks spread out along the window, affecting both the upper and lower floors.

very good.

Before the fight actually started, Natsume-san was about to tear down half of the building where Branch 177 was located.

Coupled with the detonation caused by the high-temperature sphere, the outside of the house immediately became a mess.

The bicycle that Senior Sister Gufa used to get around was placed near the flower bed downstairs. It was swept away by the blast and no one knew where it fell.

Natsume felt a little guilty because he had broken some things again.

Fortunately, the explosion took place quite far from the branch office, otherwise Hatsuharu and her classmates would have to work outdoors next time.

The current battlefield is inside the house, which is very disadvantageous for a wandering mage like Natsume.

Senior Misaka was not affected much, as the steel bars everywhere made her very suitable for fighting in narrow buildings.

Moreover, since destroying several research institutions, this senior student's combat experience in construction has increased a lot.

After Saten and the others were transferred away, Misaka-senpai was the only one left in the branch. As for the girl with a bun, she had long since blended into the environment.

The magician named Stiyl was once again covered in flames as he battled with a guy with a bun-like head for control of the air around him.

The high temperature spread along the corridor throughout the entire building, and as the door handle melted, the high heat also invaded the branch.

The three magical girls were also on high alert at this time, chanting something. The fallen wall debris suddenly gathered together to form a thick protective shield.

The original question has now been answered. The ability of the remaining magical girl should be to control the soil.

In this way, the four people in front of him just happen to have the four elements of earth, fire, wind and water, which are rumored to be the four elements that a certain ancient civilization believed to constitute the world.

The magical girls, wearing thick mud armor and with water balls on their heads, looked at each other, pushed open the door with a burnt lock, and entered the Discipline Committee Branch 177.

But Stiyl stood quietly, ready to respond to any emergency at any time.

"Master, there is no one inside."

Although there is a barrier of water, sound can still be transmitted through the liquid.

Magical girl Mary spoke loudly, but her voice was so faint in Stiyl's ears.

"Space...Move"

His pupils dilated slightly as someone suddenly appeared next to Stiyl.

The cigarette in Steele's mouth fell to the ground, and his body was suddenly hit by a huge force.

The whole person hunched over like a cooked shrimp, and couldn't help spitting out some saliva from his mouth.

With her arm held by Shirai-san and her body covered with half a thick layer of fine iron sand, the girl named Misaka Mikoto fell from the sky, enduring the high temperature around her and punching hard.

Shirai-san is unable to move anything heavier than 130 kilograms, so Misaka-san can only place iron sand on the front side facing the high temperature, with the back directly exposed to the air.
