Temperature Control in Academy City

The nitrogen around the body had been drained away, and only the area around the body still maintained a relatively normal air pressure. The nitrogen formed a thin barrier that blocked the falling snow from the sky, and soon the barrier above the head was covered with heavy snowflakes.

The same was true underfoot. The ice spread very quickly and the ground began to rise suddenly. Every step you took had to consider whether you would fall.

"Cough, cough." Takitsubo Rikou had some difficulty breathing, and her face gradually became dull and weak.

Although Kinuhata still had a firm control over the air within a few meters, with his two arms raised high to hold up the nitrogen armor, the invasion of the vacuum was unstoppable, and it was only a matter of time at most.

After all, it is impossible for Juanqi to perfectly control all the air he uses. Under the influence of the laws of physics, there will always be gas that escapes control and rises away. This also leads to a greater disadvantage for the "prop" side, and the advantage of a longer casting distance becomes prominent.

Ever since a certain bun-head became level 4, the longest straight-line distance he can affect (with a certain person as the origin) has not increased as fast as the computing power. Except for an increase of a few meters as the computing power increases, there has been basically no change.

But this is certain. You must know that Natsume Sonoko's ability range can actually be regarded as a three-dimensional sphere, and the farthest distance can be regarded as the radius of the sphere.

In mathematics, the formula for calculating the volume of a sphere is four-thirds times pi times the radius cubed.

As the radius increases, the volume of the sphere will expand dramatically. Once it reaches a large base number, such as Natsume Sonoko's more than 100 meters, each meter of increase will require much greater cost and energy than before, which is why the growth seems slow.

Coming back from the math problems that Natsume Sonoko was good at, someone frowned slightly and looked at the prop duo who were still persisting.

What a tough opponent! Although the conflict had only been going on for less than five minutes, the fighting on the battlefield was already going on with great pleasure.

A certain Natsume Sonoko came all the way here and launched the attack, but she didn't think it was her fault. She thought it was all the fault of these annoying Anbu organizations, otherwise she should be staying in the dormitory now and thinking about how to help Senior Misaka.

At this time, a very interesting phenomenon appeared on the road. Cold air currents and hot air currents existed at the same time. Someone was controlling them carefully so as not to accidentally break the boundaries he set and let the cold and hot mix together to form a summer rainstorm that was harmless to humans and animals.

Anyway, it's just like ice and fire.

In order to control this peaceful situation, Natsume Sonoko's computing power was consumed very quickly, but she was quite happy about it. She rarely used both the abilities of heating up and cooling down at the same time, and this experience made someone feel good.

Both hot and cold temperatures acted on the nitrogen armor, but unfortunately there was no thermal expansion or contraction to damage the armor, it only further compressed the living space.

At this moment, Kinuhata Sukai, who was confined in a small area, suddenly nodded towards Takitsubo Riko, and took out two metal can-shaped objects from somewhere in his hand, and gave one to Takitsubo Riko.

By the way, aren’t you tired of carrying so many things around all day? Natsume Sonoko didn’t even want to bring her black schoolbag to school, but it was a pity that the schoolbag couldn’t be stored in the classroom, and it was really annoying to carry it around every day.

Natsume Sonoko looked a little puzzled. Could this be some kind of high-yield bomb?

Kinuhata loved to crush the can in her hand and throw it into the sky. The hot air controlled by Natsume Sonoko immediately collapsed, as if something was absorbing heat crazily and releasing some gas.

Natsume Sonoko looked up silently. There was still thick fog all around. She could barely see the light from the moon and stars, but the temperature seemed to have dropped a little.

At this time, someone was already on high alert, and even used ice and snow to make a thick ice wall in front of him, which was four or five meters thick. For safety, Natsume Sonoko did not hesitate to use her computing power at all. Anyway, her computing power was much greater than that of the average level 4.

This lady is the well-deserved lv4 computing power ceiling.

I'm bragging again. I wonder who was the one who complained about insufficient computing power before.

Natsume Sonoko tensed her whole body with alert eyes, only to find that the thing had no other reaction except absorbing heat and releasing gas. Just when she was feeling a little strange, she found that the duo of props had begun to charge towards the other side of the ice wall. They needed to get in touch with the air again.

"We can't stop and wait for the other side to surround us. We must leave here."

Kinuhata said to Takitsubo Rikou that after all, she was a junior high school student and a part-time ANBU member, so she also understood that she could not stand in one place and fight with the girl from Tokiwadai, she had to fight while running to prevent the opponent from creating a vacuum environment.

It's not just me, it's the same for Maito and the others as well. On the contrary, because I am a user of atmosphere control abilities, I can compete with the other party in terms of consumption.

The first one to rush over was Kinuhata's favorite. Takitsubo Rikou was waiting in front of the hole in the ice wall, and then she took a deep breath and ran to Kinuhata's favorite position.

Takitsubo Rikou's ability is not suitable for combat, at least it was like that before level 5. In the Anbu organization, the 'tool' is more responsible for logistics and support. Although she looks weak and frail, her physical fitness is still ten blocks ahead of others.

Takitsubo Riko suddenly grabbed a metallic object in her hand and squeezed it hard, leaving five deep fingerprints on the surface of the object.

Throwing something into this false vacuum in the direction that Kinuhata likes the most, a bunch of gas will instantly come out of this can-like thing.

"..."

"What a strong hand." Natsume Sonoko murmured to herself, as if she was always concerned about some trivial things.

Natsume Sonoko touched her chin, like a thoughtful wise man.

Then dozens of huge battering rams fell from the sky one after another and landed beside Juanqi's beloved.

Instead of hitting Kinuhata's beloved head directly, it deviated from the target at some angle, and it would be done as long as the nitrogen armor was destroyed.

In this vacuum environment, the nitrogen that maintains the nitrogen armor can no longer be replenished. To destroy it, one only needs to maintain continuous attacks, and the defensive power of the nitrogen armor is greatly reduced.

But contrary to Natsume Sonoko's expectations, her attack did not work. The nitrogen armor was still intact and even had time to stop and protect Takitsubo Riko.

"So the contents of those cans are actually nitrogen. No, it should be liquid nitrogen." I finally understood a little. It turns out that these dark guys actually carry this kind of thing.

Natsume Sonoko had a somewhat unhappy look on her face and could only watch Takitsubo Riko and the others escape from the false vacuum zone they had created.

"Why are you running? I'm not a bad guy." Natsume Sonoko complained in her heart. She was just sending you to the security guards, and it wouldn't be so easy to run away.

Just when the two props team had just escaped from the pseudo-vacuum area, before they could even breathe a sigh of relief, they suddenly found that the road under their feet became empty, as if there was nothing there.

Kinuhata Saiai and Takitsubo Rikou looked at each other, their hair flying in the air like fluttering butterflies, and they both began to fall rapidly.

thump.

This was the sound of falling into the river, causing a splash of water, bubbles began to appear, and the two of them sank to the middle of the river.

When the two "props" team landed on the river near the road, the river immediately began to freeze. Even though they still had nitrogen armor on their bodies, the ice layer covered them together with the nitrogen armor.

There are three layers inside and three layers outside, just like the fried lasagna made by a restaurant called Golden Bakery in the underground street of the Seventh School District.

In just a few seconds, the two people were frozen tightly and floated from the center of the river to the surface. A large ice ball with a diameter of seven or eight meters floated on the water.

A head popped up on both sides of the ice puck. One was Kinuhata, who looked a little sad and thought he was tricked. The other was Takitsubo Riko, who had a look of inexplicable excitement in her eyes.

Kinuhata's favorite was still covered in nitrogen armor, but he couldn't even move his fingers. The pressure inside the ice ball made the two of them unable to move. Even if their physical fitness was strong, it was of no use in this situation.

If the puck is allowed to roll and there is no place for the opponent to gain leverage, it will be even more impossible to escape.

"A great success." A look of joy finally appeared on Natsume Sonoko's face, and the smile at the corners of her mouth was about to reach her ears.

She seemed to have remembered the school rules of Tokiwadai again. The smiles of the young ladies should be elegant and charming. Natsume Sonoko still cared a lot about school rules and regulations, and her face became dull again.

As for the incident of secretly sneaking out at night without telling the dorm supervisor, Natsume Sonoko said that these were all understandable and were all for the sake of protecting the peace of Academy City and should not be confused, so I am still a good student of Tokiwadai Junior High School.

"As long as I take action and use my brain and some tricks, there will be no enemy that I cannot defeat."

At this moment, someone's self-confidence began to explode, and he felt a little proud of having succeeded in doing something bad.

"Takitsubo, do you know what happened?" The two heads were located on both sides of the ice ball and could only barely see the opposite side, but their health was still good.

"We must have run into the river. What a strange feeling." Takitsubo Rikou lazily lay in the ice ball, her head slightly leaning against the surface, looking at the stars in the night sky comfortably.

"It's so weird. We were clearly running towards the road, how could we end up in the river?" Juanqi Zuiai was a little puzzled. With a look of unwillingness to admit defeat on his face, he slammed his head against the surface of the ball in an attempt to leave the sphere, but ended up getting a face full of snowflakes.

"Pfft." When Takitsubo Rikou saw Kinuhata's face covered with snowflakes, a faint smile appeared on the corner of her mouth.

"She can hide her body and replicate her image, so she must also have the ability to control light. That's why she wants us to see the road as a river, and the river as a road. For example, by changing the angle of light on the road, she can change the position of the road in our eyes."

Takitsubo Rikou spoke up, with a hint of inexplicable emotion on her face.

"Besides, the fog was so thick that we couldn't tell the direction, right?"

"But we were clearly running towards the opposite side of the ice wall. The ice wall was right in the middle of the road at the beginning. We shouldn't have run in the wrong direction." Juanqi Zuiai said somewhat unconvinced.

"In fact, if we just slightly change the angle of the ice wall, we will be confused." Takitsubo Rikou said with a sigh.

"This is terrible." Kinuhata's favorite was quite disheartened. As members of the Anbu, they knew their fate from the beginning. The death rate of the Anbu was never just a piece of data on a computer screen for them.

"Actually, there's no need to worry so much. The other party doesn't seem to have much ill intentions." Takitsubo Rikou said lazily, looking at the night sky.

At this time, a certain Natsume Sonoko also fell to the ground, saving some computing power.

The fog that filled the road no longer persisted, and began to dissipate along with the hot and cold air, leaving only its optical invisibility and the "prison" that reinforced the two people that Kinuhata loved the most.

"This is a bit difficult. Should we hand over such a big ice ball to the security guards?"

Natsume Sonoko, who had just won a victory, looked at such a big ice ball with some difficulty. If she opened the ice ball, she was worried that they would run away. If she didn't open it, how to transport it would be a big problem.

Just when someone was looking at the two prop organization members at a loss, the phone at hand suddenly rang.

"It's Shirai-san." Natsume Sonoko was stunned for a moment and answered the call from Shirai-san.

"Natsume-san, where have you been? Why haven't you answered the phone?" Natsume Sonoko then realized that there were four or five missed calls on her phone, but she was too focused at the time to notice.

"Don't worry, I'm fine. Shirai-san, I'm telling you in secret, I caught those two bad guys." Natsume Sonoko said with some pride (??????)??

Chapter 128 Teacher, I want to report a crime

"---Ah, Natsume-san, you are not bragging." A look of doubt appeared on Shirai-san's face.

"No, Shirai-san, don't look down on me."

Along with some other noises, the voice of Natsume Sonoko and the gurgling sound of the river came over. The river was blocked in the middle by someone, causing the water to be unable to flow smoothly.

Sitting on a drive armor, Shirai-san's bloodstained coat was thrown aside, and behind him was Uiharu-san who was conscientiously helping to re-treat the wound.

"Well, luckily I had first aid medicine with me, otherwise Shirai-san's injuries might have become more serious."

Carefully, Hatsuharu squeezed out a gel-like substance from the hose and applied it carefully around the wound where the flesh was about to fester, causing Shirai to groan.

This kind of medicine has not been widely distributed among the discipline committee members. I heard that it will only be officially used as a daily supply for the discipline committee members in a few months. However, Shirai-san got a lot of it from somewhere, and Hatsuharu carried some with her.

These jelly-like substances are very effective. They can disinfect and stop bleeding, and can also heal wounds. They are suitable for most external injuries. The inventor of this medicine is actually the familiar ghost-chasing doctor in the underworld.

"Shirai-san, you are too reckless. You are trying to be brave even though you are seriously injured." There were tears on Hatsuharu's face. She looked at the wound on Shirai's body with some heartache and said in a reproachful manner.

"Hatsuharu, you're here too. How's the situation over there?" Natsume Sonoko's voice came from the speaker of the cell phone.

"Natsume-san, we are fine here. We have also notified the security guards and they will be here soon." Uiharu came closer and said to Natsume Sonoko on the other end of the phone.

"That's good. I'll hang up first. Judging from the distance, the security guard should be here first."

"There is one more thing, Natsume-san. We found something from Therestina, the woman from MAR. Hmm... Actually, I'm not sure, but it seems to be a sample for the ability body crystallization experiment."

Ms. Shirai continued to say that she had looked up relevant information and had a basic understanding of these 'body crystals'.

Shirai-san was holding a delicate glass container in her hand, which was about the thickness of a thumb. It was filled with liquid and a red crystalline substance was floating on top.

"The 'body crystal' found on Therese Tina?" Natsume Sonoko said "eh".

"Really!"

"of course it's true."

After hanging up the phone, Natsume Sonoko suddenly had a complicated feeling in her heart, somewhat unexpected, but also relieved.

After carefully checking the high-definition picture sent by Mr. Shirai, I couldn't find any problems. It looks like there should be no mistake. It should be the original sample.

Someone has been worried that there might be problems with the information he found. Now that the original sample has been found, it would be most appropriate to use the original sample as a benchmark. Fortunately, the final version of the inhibition test has not yet begun.

After coming to her senses from this news, Natsume Sonoko finally looked at the two uninvited guests in front of her.

Natsume Sonoko ran to the river and walked on the frozen river surface in a methodical manner.

The river water began to flow, and a powerful gun floated from the water. It was the gun that Kinuhata loved the most. An icy hand stretched out from the ice and handed it to Natsume Sonoko.

Someone tinkered with it for a while, and based on what he had seen from movies, TV, games and animations, he estimated that it wasn't very difficult to use, but he didn't know if the recoil was strong.

Great, another piece of evidence.

Including the human witness Banri and the others, these powerful weapons are physical evidence.

The bob-haired girl who looked up to the sky and sighed could not see Natsume Sonoko. She only saw her own gun floating in the air. It seemed that someone was fiddling with it in various ways, and the muzzle of the gun would point everywhere from time to time. It was obvious that she had not undergone any military training.

Kinuhata was very familiar with the power of his gun. Even in normal condition, the nitrogen armor on his body could not withstand the continuous bombardment of this weapon. A helpless look appeared on his face.

"Um, can you let us out? I'm almost freezing. I promise I won't run around."

Takitsubo's hair was a little wet after the cut, and his body was wrapped in a thick layer of ice. His body temperature was losing quickly, and his face was strangely red. He really looked a little frozen.

"Hey, Takitsubo, what are you talking about? We are the Anbu, how can we negotiate with the enemy? That's so lame." Kinuhata Zuiai looked at Takitsubo Rihou in surprise.

Influenced by the aim positions of others, Takitsubo Rikou's words and deeds are much more erratic than those of ordinary people. By observing and sensing different aim positions, she sometimes has an inexplicable "sixth sense", and she also attaches great importance to this feeling.

Natsume Sonoko was a little surprised. She put aside the gun that she had originally intended to give to the guards as evidence, and looked at this lazy girl in summer sportswear and short hair with bangs with some surprise.

"You were able to spot me before? Is it related to your ability?"

Natsume Sonoko also responded very naturally. After a moment of silence, she actually started talking to Takitsubo Riko. For some reason, the two of them were connected online.

"My ability is 'ability tracking'. I can sense other people's aim positions and find out where you are." Takitsubo Rikou said without hiding anything.

"That's right, no wonder."

With her mouth slightly opened, Natsume Sonoko nodded in understanding. She had already had some guesses, but now she finally figured it out. There really is someone with the ability of the AIM stance system.

"Well, it's not impossible for me to let you out, but you have to stay in a fixed place. If you take one more step, I will not be polite. And I will definitely not let out the violent guy next to you."

Natsume Sonoko glanced at Takitsubo Ri, hesitated for a moment and then nodded. She looked a little frail, but it was strange that she had such strong hands.
