Temperature Control in Academy City

Thunder roared suddenly out of nowhere, and the sound echoed throughout half of the Academy City. Some people who were accustomed to wandering at night couldn't help but turn their eyes to the sky.

The disordered air pressure caused a series of strange phenomena, and coupled with the disappearance of nearby low-level clouds, the sky appeared extremely bright and strange under the illumination of the moon and stars.

"What is that?" A guy hiding in the dark looked at the sky in amazement, as if two huge air pressures were constantly colliding, forming circles of white air circles that were constantly spurting and exploding in between.

"Captain, can you see anything?"

Sitting on the roof, the captain of the Ghoul Corps was looking up at the sky, with Naru, who looked curious, next to him.

"The air flow over there is too chaotic. I can't see anything clearly." Captain Rize Iisu shook her head helplessly.

Looking at the vortex of air that suddenly slashed towards him in front of him, Natsume-san had an inexplicable seriousness on his face.

Although he had noticed Accelerator's actions a long time ago, it was not until Accelerator launched the attack that he truly felt the huge threat.

This threat is even greater than the previous aerial chase between the two, because at that time he could at least make a strategic shift, but now the situation has become different.

Natsume is still controlling the airflow around Accelerator. No matter how much Accelerator diverts, he will heat himself up to ensure that Accelerator cannot dissipate heat well.

This was a situation she had created with great difficulty, so naturally she was unwilling to give up easily. At this time, Natsume rarely thought of shifting her strategy and began to go all out.

The current situation seems to have turned into a protracted war, but Accelerator wants to change the current situation.

So as soon as he made a move, even though he was not in good condition, Accelerator used his computing power to form a huge air vortex, and as soon as this air vortex was formed, he turned the gun to attack Natsume Sonoko.

Natsume's control range was about a hundred meters around himself, but now this range was quickly compressed in a short period of time, and the opponent's fierce offensive took away many positions, just like a big apple with a hole bitten off.

Natsume stepped back a little and increased his control range again, but he also made sure that he could still control Accelerator. Although the air pressure on Accelerator's side was no longer under his control, he could still exert influence through heating.

But soon, the air pressure around Natsume was gradually twisted and squeezed, turning into Accelerator's power.

The current situation seems somewhat familiar. Natsume-san used a similar method to deal with Kinuhata Saiai before, but at that time his control range was larger, so Kinuhata Saiai was suppressed by him.

However, the only good thing is that Accelerator cannot block his contact with the air. He must control it through skin contact. This also allows Natsume to constantly replenish his own air pressure, but it is still insignificant compared to the huge range that Accelerator can control.

Seeing his position getting smaller and smaller, Natsume became anxious.

But the next second, the girl with the bun hairstyle suddenly looked strange. Her pupils turned slightly red and blue veins began to appear near her temples.

This means that Natsume's use of the biological computer's computing power has exceeded his authority. At this time, the power of the Fantasy Hand begins to take effect, allowing Natsume to gain more authority.

Through the connection of the fantasy hand, more than half of Natsume Sonoko's thoughts entered Zero's body, using Zero's brain to continuously operate the biological computer.

By dividing her mind into two parts, Natsume Sonoko's concentration level decreased slightly, but her computing power increased rapidly.

Now Natsume has used more than half of the computing power of the biological computer, which is at least twice that of the ordinary level 5. Moreover, the biological computer is tireless and can continue to calculate.

Although Natsume's computing power is only used to maintain contact with Zero, with the onset of red-eye disease, the consumption of his own computing power begins to increase exponentially. If he wants to pry open the lever, he must also come up with something on his side.

Natsume Sonoko's real body narrowed her eyes slightly. As the scene became more and more chaotic, her vision and heat sense were no longer of much use.

He can only rely on the recognition method of his ability itself to locate Accelerator. In fact, his ability cannot directly act on the human body, so a vacuum area will appear in his perception.

Chapter 152 Extreme State

As if sensing that Accelerator's position has not changed, Natsume-san's red eyes flash with an inexplicable light.

The two people seemed to have a tacit understanding and fought to the death in the sky.

Natsume Sonoko was trying to gain the advantage with great difficulty, while Accelerator was trying to make Natsume stay quietly in one place and not move.

In many ways, Accelerator is an absolute genius. Even though his experience in the air is far less than that of Natsume Sonoko, who flies into the sky every other day, he can still reach a flying speed that exceeds that of old fighter jets in a very short time.

Fortunately, Natsume is now faster. In addition to Natsume's long-term improvement of formulas and accumulation of flight experience, he also used a biological computer to optimize the formula again in the past few days. The key to maintaining this advantage is also the free-spending computing power.

However, Natsume was not sure whether he could still maintain his current advantage after Accelerator carefully studied the flying formula. This made Natsume feel a sense of urgency.

But if that's the case, then today's opportunity is a big one.

And judging from the situation, Accelerator who was not far away had no intention of letting him leave. In fact, the current situation was more caused by Accelerator's relentless pursuit of him.

Strictly speaking, Natsume-san was just fighting back and defending himself.

A certain girl with a bun-like head who has always been eager to help others, diligent and studious, and contentedly been an ordinary student in Academy City, felt for the first time that she had such a great pressure on herself.

However, he could not care about the pressure. Natsume didn't even think about Accelerator's appearance. He just concentrated his firepower on heating the air around Accelerator, and at the same time resisted the air vortex above him that was becoming heavier and heavier.

As Accelerator gathered more and more air, and the position of the air vortex was above Natsume Sonoko, Accelerator's advantage became more and more obvious, and gravity was on the other side, oppressing the man's vitality.

Natsume Sonoko blinked her slightly red eyes, and her entire skin began to turn red. As the consumption increased, Natsume's breathing also became rapid.

As the pressure increased, in order to resist the increasingly heavy air, Natsume also began to compress the air, continuously absorbing air from all around to replenish his own air pressure circle.

As Zero's output power increased, the computing power that Natsume could control also began to increase. Not only did it stop the downward trend, it also slightly turned the situation around. The air pressure controlled by Natsume Sonoko turned into a slightly concave round sphere.

In order to prevent the air within his control from being swept away by Accelerator's vortex, Natsume deliberately let his air pressure form a small clockwise cyclone, which was exactly opposite to the direction of Accelerator's movement.

It seemed that due to the opposite directions, the ionized bodies originally formed at the center of the two people's air pressure did not gather together, but began to dissipate continuously, forming a scene of white light spots in the sky that continued to radiate in all directions.

However, this also gave Natsume some untimely inspiration. Under high temperature, the friction between air can generate electricity, and it does not seem to be very difficult to achieve.

A certain girl with a ball head unconsciously put the development of power generation capacity on her schedule. Maybe she won’t need to carry a charger in the future.

Putting aside irrelevant matters, Accelerator is still in a bad state right now, and it is getting worse as time goes by.

Although the heat in the body was dissipating with sweat, it also took away a lot of water from Accelerator.

Dehydration or high fever, this is a very difficult choice.

However, Accelerator obviously chose dehydration. Dehydration will also cause the brain to function more slowly, but it is not as serious as burning the brain.

Sweat obscured Accelerator's vision, and his black and white T-shirt became wet, but his expression became more and more excited, and the corners of his mouth involuntarily curled up slightly.

"It was blocked. What a surprise! The next step is to decide the winner."

Accelerator no longer cared about the high temperature in his body and his physical weakness. He mobilized all the remaining computing power that could be used. The computing power that burst out in a short period of time brought Accelerator back to his peak state.

The next second, a huge flaw immediately appeared in the situation that was originally evenly matched. The air pressure around Natsume was immediately torn into a hole, and an increasingly powerful airflow squeezed in from this hole, cutting off Natsume's control range in the middle.

The area that was cut off in the middle lost its support and was easily dominated by Accelerator, like a rootless duckweed.

The situation is now becoming more and more dangerous, and Natsume can only continue to increase Zero's computing power output.

Natsume's eyes became redder and redder. Half of the color in his eye sockets turned red, and there were even a lot of bloodshot in his originally black pupils. He looked like he had been staying up late for many days.

Sixty percent, the biological computer has released a total of sixty percent of its computing power, and fully invested it in the battlefield far in the sky. With the help of this computing power, Natsume continues to release formulas, strengthens his own defenses, and his breathing becomes more and more rapid.

Natsume's brain became groggy, and only 40% of his thinking power remained in his body. This was the minimum required to allow his body to deal with certain situations normally.

Also because of the long-term and high-intensity use of the ability, blood began to flow from Natsume's nostrils, dripping onto his clothes, and his entire face appeared an unnatural red.

On the other side, Reiko, who had returned to Misaka Apartment, was lying weakly in the room.

A series of problems also arise with Reiko, because if Natsume wants to use the biological computer, he must first go through Reiko's brain.

Although it was only using Zero's brain to issue instructions to the biological computer to perform calculations, because the instructions were too many and too dense, Zero's brain was in a state of overload and the temperature of the brain began to rise.

Zero's brain is fully developed, but because his abilities have not yet been developed, he is actually similar to an ordinary level 0.

In order to reduce unnecessary consumption, Lingzi took the posture of looking up at the sky, but now Lingzi's face was red, and he only put a large piece of ice on his forehead to cool down. As it thawed, Lingzi's clothes became wet.

Diverting 60% of one's thoughts is not only Natsume's limit now, but also Zero's limit. Moreover, Zero's situation will be even worse.

Chapter 153: Reversal of Situation

As if he had noticed the situation on Rei's side, Natsume hurriedly reduced the input and calculation frequency of some of the biological computers.

Coupled with the increasingly powerful offensive from Accelerator, the circular sphere controlled by Natsume was suddenly reduced by half. He could only hide in the corner and had almost given up the idea of ​​confronting Accelerator head-on.

Even if the biological computer is tireless, I and Zero cannot do it.

As the area that Natsume gave up became larger, the demand for computing power decreased slightly, but the feeling of oppression increased in vain.

Accelerator's air vortex was growing bigger and bigger, drawing in more and more air currents, almost wrapping up Natsume-san inside.

The red color in Natsume's eyes became lighter, and his extra thinking ability returned. He also noticed that his nose was bleeding continuously. He raised his head and pinched his philtrum, trying to stop the bleeding in a scientific way.

However, before Natsume could stop the bleeding, the situation changed again.

The air vortex that was originally oppressing Natsume began to slow down.

The intensity of the previously aggressive attack suddenly slowed down, and some of the gases on the outer layer of the vortex drifted away into the distance.

Accelerator held his forehead with his hand, a hint of disgust on his face.

Behind him, a stream of extremely cold air suddenly appeared, with the temperature almost reaching minus eighty degrees Celsius.

The moment this cold air appeared, it was swept away by the violent wind and waves nearby, but the moment the cold air was swept away, new cold air appeared again, and the cycle continued.

It was a very familiar routine, and Accelerator naturally knew what was going on.

The stalemate with the ability user has lasted until now. What he couldn't understand was when a person with such a high level of computing power appeared in Academy City. For him, it was like discovering a new world.

Mixed together by extremely cold and extremely hot air, the sweat that flowed out of Accelerator was blown by the cold air and turned into a shallow layer of ice that attached to Accelerator's body.

The shallow layer of ice immediately turned into dust in the air, and Accelerator felt his hair stand on end.

Facing this sudden gust of cold air, it only took a blink of an eye for Accelerator to urgently control the heat behind him to prevent the heat from instantly flowing out and causing destructive frostbite to the body.

As if he had thought of something, Accelerator's face darkened.

He had already realized the seriousness of the problem. In addition to the cold air, the other party actually used the huge wind speed created by himself, which made Accelerator suddenly feel a tightness in his chest.

If a human is exposed to air dozens of degrees below zero, he may be able to survive for a period of time. If he wears special protective clothing, he may be able to carry out some activities.

But if you are in air dozens of degrees below zero and encounter an unprecedented storm, and you are only wearing a short-sleeved T-shirt, as long as you are exposed to this fast-flowing cold air, the heat it takes away in an instant will be several times or even more times than the heat taken away by still air.

For example, in air at minus 50 degrees, if there is a wind of ten meters per second, the rate of heat loss may be equivalent to staying in still air at minus 100 degrees.

And because of Accelerator's active control, the wind speed around him has almost reached 60 meters per second, even comparable to the speed of some typhoons. If you are blown by extremely low-temperature cold wind at this speed, the muscles on the surface of the body will be frostbitten immediately.

There was a constant alternation of cold air behind Accelerator. Although there was still hot air in front of him, Accelerator did not dare to be careless. He immediately controlled the heat from his whole body to return to his body to prevent the other party from suddenly changing the temperature.

At this time, Natsume thought the same as Accelerator. The hot air in front of Accelerator suddenly disappeared, leaving only the sub-zero temperature air covering Accelerator. With the storm raging around, the cold air flowed faster and faster, and the cold white frost almost covered Accelerator's body.

"The speed of the air vortex is decreasing."

Because of the sudden reduction in positive pressure, Natsume sensed this change immediately, and his thoughts worked again.

As Accelerator continued to transfer the air around him, Natsume suddenly thought of using cold air.

According to the current temperature, Natsume-san can only cool down to around -80 degrees Celsius.

Just like what was said before, although minus eighty degrees is cold, Accelerator can risk frostbite and only be exposed to it for a very short time to lower his body temperature, so Natsume-san did not use cold air before.

But with the appearance of the air vortex, the wind speed was extremely high. At this time, even a contact of just one second would cause serious damage to Accelerator's body.

Accelerator obviously knew this knowledge, and he chose to control his own temperature at the first moment instead of being exposed to the low temperature air in this situation.

Due to the threat of low-temperature air, Accelerator chose to stop his already large-scale cyclone and had to give up the plan to use computing power to break through the opponent's fortress.

It has to be said that Accelerator's behavior was very decisive. He gave up the advantageous situation in an instant to avoid a worse future. It can be said that the current situation has changed dramatically once again.

Accelerator's body temperature problem still has not been solved. If he continues to maintain this high-speed rotating air vortex, then he will not be able to release the heat in his body. It won't be long before the high temperature in his body will become so serious that it cannot be calculated.

And Accelerator also did not choose to leave. On the one hand, his pride prevented him from doing so. On the other hand, if he did so, he would become even more idle. His flying speed was not as fast as Natsume's.

At this time, Accelerator also made up his mind to focus on developing his flying speed in the future to prevent this situation from happening again.

As the air vortex in the sky gradually decreased, the position controlled by Accelerator was immediately taken over by someone, allowing Natsume's control of the air to expand to Accelerator's surroundings.

The position that Accelerator doesn't want is very important to Natsume, and there are actually a lot of things she can do.

When the speed of the air vortex gradually slowed down, the cold air around Accelerator quickly disappeared and turned into high-temperature air again, preventing Accelerator from dissipating heat.

Natsume-san no longer has to maintain the confrontation with Accelerator at this time, and the consumption of computing power seems to have been greatly slowed down.

Chapter 154 Ending

The two huge tornadoes behind him made a whistling sound.

Standing high in the air, he pinched his nose with one hand to stop the nosebleed, and subconsciously touched the blood stains on his face with the other hand, which immediately turned his face into a clown face. The guy with a bun tried hard to maintain a serious expression and looked directly at Accelerator who was not far away.

The tension in Natsume Sonoko's heart did not relax at all, and the pressure became greater and greater as time passed.

Someone didn't know how long the white-haired guy on the opposite side could hold on, but he just felt that he was about to be finished.
