[1] One party passes

(Forbidden World, Thursday, July 18, 2013, morning; School City, School District 15)

In the scorching summer, the sun is like fire, but there is not much cool breeze. The air above the road surface was distorted by the heat, and the steaming of the lawns and flower beds that had just been sprinkled in the morning made pedestrians who were already struggling with the heat feel even tighter and panting, and they wanted to dive into the air-conditioned room to cool off.

"I really miss the air conditioner in the convenience store just now......" The girl with brown hair and eyes sipped on the refrigerated juice in the can, and suddenly turned her head to look at the side passing, "So why do you have such a perverted ability......! It's not fair at all, okay!"

"That, Misaka-san, the type of ability or something, it's not something I can control. ”

Fang Tong smiled helplessly, since he had awakened the rather powerful ability of [Vector Manipulation], and the ability level was as high as Level 5, this strong girl seemed a little depressed. Thinking about how to help the other party cool down, he looked down at his palm, and a flash of inspiration flashed in his mind, and he suddenly had an idea.

"By the way, Misaka-san, can you get a little closer to me?"

"Huh? yes, okay. ”

The other party leaned towards him as he said, and their arms were almost close together.

"Is this distance okay?"

"Totally sufficient!...... then"

With the ability of one side to pass, a cool breeze blew from his side towards Mikoto Misaka on his side.

"Oh! that's amazing!'re so comfortable!" Mikoto Misaka exclaimed, then blinked at him, "Is it a new way to use your abilities?"

"That's right. The so-called ability is to use it flexibly to achieve greater value. ”

Fang Tong raised his eyebrows a little proudly, very satisfied with his previous whim.

"I just thought about it, if the molecules with more kinetic energy are excluded and the molecules with less kinetic energy are absorbed, a cool breeze can be created out of thin air. But it seems a bit like Maxwell's demon. ”

"Maxwell, yes, that's what I'll call you from now on, Maxwell. ”

"Hey, I haven't agreed yet. ”

Saying this, Fang Tongtong thought of another question in his mind - that is, when the second law of thermodynamics has not been falsified, why can his ability produce such an effect? If his ability acts in a similar way to Maxwell's demon, then when he distinguishes between molecules with greater kinetic energy and molecules with less kinetic energy, the entropy of the manipulated air decreases, but the information storage unit- That is, his thinking organs will definitely store new information, that is, the entropy of information will increase, and the elimination of this information will consume a certain amount of energy and lead to an increase in the entropy of the environment.

However, he also thought that the human brain could never approach the limit of Randall's principle for storing and eliminating information—that is, the least amount of energy required to erase 1 bit of information is kTln2, where k is the Boltzmann constant and T is the ambient temperature, and erasing 1 bit of information will result in the same amount of heat being released into the environment. As long as his physical mortal is still metabolizing, and his cells are still hydrolyzing ATP to release heat, it is impossible to accurately measure how energy, information, and entropy change in the process of creating a cool breeze.

"What are you thinking about? That's pretty rude!"

Mikoto Misaka tilted her head to look at him for a moment, and suddenly kicked him lightly.

"I'm leaving tomorrow, I don't have a good time today, I'm still thinking about those headaches, you're enough!

Only then did one party remember that in less than twenty-four hours, the other party's parents would come to pick her up, which was also the norm for most of the students around her. Of course, an adopted orphan like him is no longer among them.

"Well, it's me who is wrong, let's speed up. ”

Trotting all the way to the institute, the two men stood in front of the door, the scanner's beam — a device designed by Vikz that detected much more than visible light — streaked across them, and the metallic door opened automatically, welcoming them in.

"The portal straight to the basement is ready, and Zhiyin and I are adjusting something. ”

Sora Akiyama's voice sounded in his head. Easily through the elevator to the fourth basement floor, Fang Tong stepped into the bottomless abyss-like void door with anticipation, everything in the field of vision suddenly disappeared, and then the scene in front of him suddenly lit up.

In the slightly raised viewing angle, in the crystal clear blue sky, clouds flutter at a speed visible to the naked eye under the action of the wind, and the blue-purple morning sun rises from the sky. Looking down and staring at eye level, the place that comes into view is a simple and elegant house: there are five main gates, the doors and windows are all finely carved three-dimensional shapes, how do they look like they are wooden colors, and there is no vermilion mountain lacquer decoration; the tiles on the top of the roof ridge are like a round barrel, like the back of a loach, and it seems to be called "bucket tile loach ridge" in memory; the white wall and gray tiles, the bluestone platform rock, the pavilions and platforms are uneven, the corridor is tactful, beautiful and refined, simple and simple.

Fang Tong subconsciously took a step forward, but unexpectedly, the whole person jumped up more than a meter high, and then slowly fell to the ground. Looking sideways, the girl next to her flew directly over the courtyard wall, landed on all fours in a rush, and then got up slightly embarrassed.

"This world is modeled after my dreams and that of Jiyin, and the gravity is lower than the earth's surface, so be careful when walking. Sora Akiyama's voice came from behind him, and the two of them turned around when they heard this, "Oh, by the way, there are two pairs of shoes for you, maybe it will help you adapt better here." ”

In the opponent's hands were two pairs of leather boots that were red all over the body, and the golden magic pattern stretched from one side of the boot to the other side, and the wing-like sigils emitted a faint white light on both sides. Seeing this familiar shape, Fang Tong couldn't help but be stunned for a moment, and then asked with some disbelief:

"This ...... It can't be flying shoes, right?"

"That's right. Feet with wings, flying away. How about it? You can also change the appearance!"

Without waiting for one party to say anything, Mikoto Misaka had already taken one of the pairs with great interest, and then changed it on the spot. The soft glow lit up, then faded, and the boots were already exactly the same as the original. Seeing this, he also tried to change into another pair of flying shoes, feeling how the objects under his feet changed shape according to his thoughts.

"Whew...... It's a magical creation. ”

Fang Tong tapped the floor with his toes, and the lightness of his body was even more light than before he changed his shoes, but he had a more sense of control, and his center of gravity was not unstable because of this. I have to say that although these two have not slipped a little bit compared to the power of the creator level, they have indeed brought them a lot of joy.

"One side, Mikoto, would you like to come in and have a visit?" Nanamiya Tomoon smiled and beckoned to him and Mikoto Misaka, "This is the courtyard and garden that I designed with Sora." ”

Following the two of them into the gate of the house, one side passed and looked forward, only to see all kinds of strange stones arched vertically and horizontally, with moss spots on it, covered by vines, and a sheep intestine path looming in it. Walking slowly along the path, they passed through the natural stone cave in the deep depths, but saw beautiful trees and green trees, strange flowers shining, there are also small bridges and flowing water, and the hidden pond of the curved cave.

Then go deep and travel a few steps, into the eye suddenly become open, both sides of the flying building plugged in the air, carved embroidered sill, are hidden in the rockery between the ancient trees. The blue waves in the central Caixia lotus pond are lightly swaying, and the reflection of the virtual and real reality does not really correspond to the building itself, like a dream, and inexplicably there is a little bit of clear water out of the hibiscus, and the feeling of natural carving.

Just walking, there is no need to carve the meaning to explore anything, and a sense of tranquility and peace will naturally spring up in the bottom of the heart, and one party does not even want to think about how ingenious those exquisite wood carvings are, and how those pine and strong bamboos reflect the beauty of geometry, and do not want to let the pale language break the soft and pouring bamboo sound like water.

I don't know how long it passed quietly, and the white-clothed Akiyama Sky in front of him suddenly said:

"Hawkers,I think Zhiyin and I won't be tied to you.,You can go on a tour by yourself for a while.,TP with flying shoes don't have to worry about getting lost.。 ”

"That...... Wait, I have one more question. ”

Only then did Fang Tong remember his previous doubts about his own abilities, and described them without reservation. Akiyama Sora listened calmly, and after thinking for a while, he said leisurely:

"The mainstream narrative of the school city has something to do with the Poincaré regression, that is, 'an isolated and finite system will arbitrarily approach its initial state an infinite number of times in the process of evolution', and the [personal reality] of the capable person is regarded as a break of its probability, and the theoretical models in this regard can be roughly divided into three types, but all of them are not satisfactory. Although we have more means than ordinary researchers, we are also afraid of ...... Well, some unspeakable existence, and dare not venture into the deep structure of this world, and the dark secrets hidden in it. ”

"That's right...... I know. ”

One side was not stunned, and soon realized what the ambiguity between the other party's words meant—it was something that even a [Void Creator] would be afraid of, and a small mortal like him was better off staying away from it, even if it was a superpower. But on second thought, these were not things he needed to think about, and thinking too much was just adding to his troubles.

"Then Maikoto-chan, I'll flash with Sora first. Have fun!"

The disappearance of Sora Akiyama and Tomoin Nanamiya did not fluctuate without any fluctuations, and it was not the first time they had seen this kind of ability to come and go without a trace, so they were not surprised. He looked at the garden he had already walked through, and suggested to the girl beside him:

"Why don't we try to fly, I wonder what it will be like in mid-air?"

"I've wanted to try it for a long time, come on!"

With a slight touch of the toes, the figure of a passing party floated up. Viewed from above, the courtyard landscape below was originally built according to the topography, stretching from a gentle slope to the edge of the mountaintop. The interior of the summit is concave inward-like like a bowl, forming a wide basin in which a field of peach and violet lotus-like plants is flourishing, and the beautiful sea of flowers and the thin clouds at the bottom of the basin complement each other, like the legendary fairyland of Yao grass and strange flowers blooming.

"Oh!"

After a brief moment of surprise, the two looked at each other and flew towards the center of the sea of flowers at the same time. As soon as he landed, he felt the softness under his feet, and couldn't help but lean over curiously to twist a petal, only to feel that the hand was smooth like jade, and the cold texture was very comfortable.

It doesn't seem like a material that ordinary plants can have...... He was wondering if he could use his abilities to explore—perhaps even decompose—the plant beneath his feet—just as Sora Akiyama had once mentioned to him, when a crisp voice in his ears interrupted his thoughts.

"Hehe, I bet you won't be able to catch up if you don't have the ability!"

"Oh, if that's what you say, let's try it!"

The corners of Fang Tong's mouth were raised, and suddenly there was wind under his feet, and his body was like an arrow from the string. Unexpectedly, the girl seemed to be prepared, jumped directly into the air, and then flew out of the sea of flowers.

"You must have planned it a long time ago, right?"

"That's right, that's it, I didn't expect it!"

Mikoto Misaka's laughter could be heard in the distance. One side of the passage immediately activated the flying shoes, and also took off into the air, flying to the edge of the mountain, and then exclaimed at the scene at the foot of the mountain. I hadn't paid much attention to it before, but now I looked down at the rolling savanna—but unlike similar scenes on earth, the trees seemed to be in no danger of water shortage, and the huge canopy was like an open green umbrella, with countless branches intertwined, and broad green leaves stretched out luxuriantly, crowded one on top of the other.

"Hee-hee, come on!"

Mikoto Misaka's figure flashed and rushed towards one of the trees. Just when one party was closely following, the crisp and loud phoenix chirp suddenly sounded, which made the two people who were immersed in the chase game suddenly wake up. I saw a big fiery red bird in the sky swooping rapidly, and the dazzling red phoenix feathers beat like flames with the flapping of its wings.

"This ...... Could it be the legendary phoenix?"

"What a beautiful ......"

Everything that happened next was as magical as a dream.,Whether it's the phoenix that carries them soaring in the sky.,Or the melt-in-the-mouth、Sweet and sweet、The spirit fruit that lightens the body and nourishes qi after eating,It's a wonderful experience that can't be experienced in the school city, a completely modern, technologically advanced city.。 When the sun was setting, he knew that the beautiful day was over.
