Chapter 7

Natsume Enako’s New Move

“According to the principle of thermal expansion and contraction, when air is heated, its volume expands and its density decreases; when it is cooled, its volume shrinks and its density increases.”

“When the air density decreases, it rises to form a low-pressure area, and when the density increases, it forms a high-pressure area. Due to the pressure difference, the air in the high-pressure area moves to the low-pressure area, which can form natural wind.”

Senior Misaka sat on the grass in the playground, still looking a little depressed. While secretly glancing at Shirai-san who was pulling weeds seriously, she patiently taught Senior Natsume Enako, who had just entered the first grade of junior high school, some simple knowledge.

“Oh, I see.”

Natsume Enako looked serious and listened to Senior Misaka’s teachings in a serious manner.

Although she didn’t take any notes, Natsume Enako said that this knowledge was actually not difficult at all, even if she had just entered junior high school.

Thermal expansion and contraction or air circulation, what Natsume Enako had known about it for a long time, but she had never thought about using it in the development of ability. Her main energy was focused on her old profession of controlling temperature. Controlling the atmosphere should be the development direction of aerodynamics.

After all, you have to learn to walk before you can learn to run, right? Natsume Enako secretly excused herself.

Senior Misaka is worthy of being able to develop a super-electromagnetic gun with her fragile palms. Not only is her computing power super strong, but she is also quite knowledgeable.

As for the development of her own temperature control ability, Natsume Enako had made some assumptions, but she had not thought about it in depth.

Natsume-san briefly recalled some of the principles and knowledge mentioned by Senior Misaka, and her brain began to speed up. Sparks of computing power splashed in the girl’s head, and Natsume Enako’s personal reality was fully released.

After a while, the originally normal temperature around her suddenly became abnormal.

Extreme cold and extreme heat exist alternately, The air around began to flow in a regular pattern.

Seeing the strong wind formed by the pressure difference blow away the sweat on Shirai-san’s face not far away, without any major mistakes, Natsume Enako immediately smiled.

Can she work part-time as an aerodynamicist now?

It seems that many level 5s can work part-time, and she really have this talent!!

Thinking of this, Natsume-san, who was thinking divergently, immediately played her special skill of learning from one example and applying it to other situations.

Natsume Enako’s palms alternated between high and low temperatures, and she used her ability to change the air pressure around her palms. The difficulty was similar to that of making Ice Guatai not long ago.

Not long after, a micro-cyclone gradually formed on Natsume’s hand. After a little relaxation, the cyclone dissipated, and a micro-air wave immediately appeared to overflow in all directions.

After trying several times, a small cyclone finally appeared steadily on Natsume Enako’s hand.

Natsume Enako blinked, as if full of curiosity about discovering a new toy.

“Compared to pure temperature control, the consumption of affecting air pressure through temperature changes is much smaller. As long as the temperature is maintained for a short period of time, the power of pressure difference can achieve a wonderful effect.” Natsume Enako tilted her head and thought to herself with a happy face.

Wind, listen to my call!

Based on the temperature range that she can control at this stage, as long as my calculation speed is fast enough, She can form a small whirlwind by constantly changing the air pressure nearby.

Under this premise, Natsume Enako can of course freely control the direction of the whirlwind.

However, if she wants to form a large-scale whirlwind or even a tornado, even if the general operation required is not fundamentally different from forming a cyclone in her hand.

But the required computing power is thousands of times different, which may burn Natsume Enako’s brain in an instant.

“Natsume-san is really smart.” Senior Misaka suddenly felt a little emotional. She just made a slight suggestion, but she didn’t expect Natsume-san to be so smart and could draw inferences so quickly.

“No, actually I didn’t control it very well, I just tried to change the temperature several times in a row.” Being praised by Senior Misaka, Natsume Enako immediately showed an embarrassed smile on her face.

Speaking of which, Senior Misaka is really nice.

She just casually said that She was a little worried about the regular test next week, Hoping to be promoted to a level 4 Great Ability person recognized by Academy City, Senior Misaka gave her advice seriously.

“Sister, Natsume-san’s calculation ability must be level 4, as long as it meets the test requirements.” Shirai Kuroko stopped what she was doing and put the weeds on the pile of grass that had already piled up into a small hill.

Shirai-san subconsciously rubbed her aching shoulders, and then walked towards the direction of her sister and the others not far away.

“Comprehensive and regular testing is what we often call physical testing. It is an inspection activity that systematizes ability and makes simple judgments according to established standards.”

“Each school will consider the accuracy, intensity, speed, distance and duration of the student’s ability release. Because as the level increases, the scope of its application becomes wider, so its evaluation items also become more complicated and multifaceted accordingly.” Shirai Kuroko said slowly, smoothing her skirt casually, and her eyes fell on the empty seat next to Senior Misaka.

Seeing that Senior Misaka did not mean to refuse, Shirai Kuroko sat down happily, and a happy smile immediately appeared on her face. But it was rare that it was not a strange smile, but rather sitting quite honestly next to Senior Misaka.

Natsume Enako did not think that Shirai-san had changed her temper, but rather that she might have changed her strategy, she couldn’t help but think with some suspicion.

“Different abilities have different evaluation methods, but as far as I know, all abilities are generally divided into two categories. The first category is extrasensory perception, and the second category is telekinesis. Among them, extrasensory perception is divided into many different sections in physical examination, while telekinesis is only divided into one section.”

Shirai Kuroko stretched out a finger, and seeing that Senior Misaka was also listening attentively, a smug smile appeared on the corner of the girl’s mouth.

“For example, my spatial movement, Natsume-san’s temperature control and my sister’s electric shock, in fact, all belong to the category of telekinesis. Although she are all in the same category, the emphasis on the detection method is different.”

“As for my spatial movement, it is determined to include three elements, that is, the size (mass) of the object when moving, the distance and accuracy.”

“If Natsume-san wants to advance to level 4, the easiest way is to work hard on several evaluation factors of temperature control, that is, the limit value of temperature change, The range of change and the accuracy of the change. As for the idea proposed by the elder sister, it can only be regarded as an application of ability at most, and cannot be calculated into the results of the physical examination.”

Shirai-san touched her chin and thought for a while, and carefully helped Natsume-san analyze the information.

Senior Misaka’s face flushed slightly, and she hugged her knees with both hands and smiled awkwardly.

“But if the air pressure difference can be developed into a super-electromagnetic gun similar to that of my sister, then maybe the school will develop a special evaluation standard for Natsume-san. As far as I know, every level 5 super ability user will have a dedicated research team.” Shirai-san added.

“By the way, what kind of old-fashioned term is a comprehensive and regular checkup? The habits of elementary school should start to change, Natsume-san.” Shirai Kuroko said, holding her forehead, as if she rarely heard such old-fashioned terms.

Natsume Enako’s face was a little red. This was indeed a habit she brought from elementary school, although there was no difference between the two.

The sun gradually descended from the center, and time passed by little by little.

The hot weather did not stop people’s enthusiasm for labor at all.

In the playground, three figures were bending over to clean up the weeds. The students of Tokiwadai Middle School who passed by were curiously looking at these three hard-working figures.

She don’t know when, Senior Misaka and Senior Natsume Enako both joined the weeding team, and the relationship between the few people became closer unconsciously.

Senior Misaka bent over to weed, and Shirai-san was working harder beside her. Natsume Enako was at the end of the team and looked a little out of breath, although she was only responsible for putting the weeds into the garbage bag.

“It’s finally over.”

After picking up the last few weeds in her sight with trembling hands, Natsume Enako couldn’t help but sit down on the playground, and her whole body was almost falling apart.

Senior Misaka was in much better condition, and she ran to the school vending machine to buy three bottles of drinks, and Shirai-san immediately took her happily.

“Strawberry soda?” Natsume Enako picked up the drink bought by Senior Misaka, and then she found that it was a rare strawberry-flavored soda.

“Sister, Natsume-san, there is still a patrol mission at the discipline committee, I’m leaving first.” Shirai Kuroko gulped down a bottle of soda, looked at Senior Misaka reluctantly, and then spoke.

As soon as the voice fell, Shirai-san disappeared without a trace, and the space movement was really enviable.

“This guy is really busy.” Senior Misaka took a sip of the drink and lay on the grass and muttered.

“Natsume-san, I have a question I’ve always wanted to ask you. Don’t you have to participate in club activities?” Senior Misaka turned around and looked curiously at Natsume Enako, who was also resting comfortably on the grass.

“Don’t worry, Senior Misaka. I’m from the Urban Legend Investigation Club. There’s no so-called activity room. Lying here can actually be considered investigating urban legends.” Natsume Enako opened one eye and looked at Senior Misaka, wondering what was going on in her head.

[When the wind turbine blades rotate in the opposite direction, something strange will happen on the street] The main body of this urban legend, Misaka Mikoto, instantly showed a surprised look, as if lamenting that there is such a club in Tokiwadai Middle School that leaves its members alone.

“That’s a really special club.” Senior Misaka said with emotion.

“It’s really special.” Natsume Enako, who thought she was investigating urban legends in a sense, nodded seriously and said with approval.
