The night in the Academy City is quiet. Since most of the citizens here are students, classrooms and scientific researchers, at this point, the night market outside gradually dispersed, and only a few streets of Songwu Town are still open for bustling business.

In the dormitory building outside the school garden of the private Changpantai Girls' Middle School, in addition to the lighting power supply in the corridors between each floor, the power and lights in each dormitory have now been cut off on time. Most of the female students of all grades have completed their own washing work before the lights are turned off and returned to their own beds, and got into their own comfortable beds, making the entire dormitory building gradually quieter...

At this time, there was no noise in the whole building, and noisy and other extra sounds were made. Only the occasional sound of engines whistling when vehicles passed by and the familiar "whimper, clattering" wheels made by the chassis wheels of guard robots everywhere as they drove past the road.

Click!

Pick! Pick!

At this time, outside the corridor of dormitory 208, he heard heavy footsteps from far to near, as if it was the last inspection before a certain wardrobe was resting? So, Mikoto Misaka and Kuroko Shirai, who were lying on the bed in the dormitory, were each curled up in their own quilts, not even breathing, for fear of attracting the attention of the terrible existence.

Smack...

Pick, pick...

Finally, not long after, the footsteps became farther and farther away, and soon disappeared at the end of the corridor. I don’t know whether to go upstairs or downstairs.

“…”

call……

There were so many things that happened today, so I lay in bed for a long time, but I don’t know how long Misaka Mikoto finally sighed in her heart after she relaxed.

Then, she began to toss and turn on the bed, trying several sleeping positions, but found that she could not fall asleep easily, nor was she sleepy... So she simply turned around and faced the wall of the single bed, opened her eyes wide, stared at the wall with beautiful patterned wallpaper in the dark, and became stunned. All kinds of thoughts came in her heart and began to immerse herself in her own world and she began to think about it.

"Hello!"

"that……"

"Sister, can't you sleep?"

After a while, maybe he noticed some of his sister Mikoto Misaka's breathing that did not become even, or maybe he couldn't sleep either. So, Kuroko Shirai thought about it, then turned her head on his bed and turned toward his sister, looking at the other person's pretty back, curled up in the quilt and asked softly, which was the first to break the quietness in the dormitory.

“…”

However, Mikoto Misaka did not answer Kuroko's question immediately, and she didn't know if she didn't hear it or didn't want to pay attention to the other party at all?

"Oh, pinch the sauce?"

After waiting for a while, the unwilling Kuroko asked softly again.

Because she is now very sure that her sister must not have fallen asleep. After all, she could hear that the other party's breathing rate was wrong at all, and it was completely different from what she looked like when she was sleeping soundly!

For Heizi, who often takes advantage of her sister's sleeping, goes to secretly shoot at night, and does some shameless secrets that are not worthy of being known to outsiders, there is really no one in this world who knows her sister better than her! She can proudly say: Sheizi has long known all about her sister, including all the information, including food, clothing, housing and transportation, hobbies, certain small movements, some strange ideas, height and weight, even three-dimensional or hemorrhoids on her body, etc.!

"Shut up, Kuroko..."

"You think that so many things have happened today, and I am not only hurt by you... Not only have you been hurt by two months of scholarships, but you are also implicated to clean the school pool for a whole week from tomorrow... So, after so many things have happened, you think I will be able to sleep as heartless as you do?!"

Without waiting for the other party to ask for the third time, Mikoto Misaka had already answered slowly and said sarcastically.

Anyway, I really can't sleep now, so I thought that the sanctuary master who just walked over would not come back so soon, and I thought I might as well deal with some annoying words from a man of a nasty man, so that the other party could not sleep and kept making trouble for me.

"ah……"

"That...Sister, let's do it. Anyway, they can't sleep now, and you can't sleep either. Otherwise, they'll come here to chat with you now?"

After saying that, Heizi quickly sat up from his bed, lifted the cup and prepared to get out of bed, intending to run to his sister's bed opposite, and squeezed into his sister's warm bed together and whispered in a low voice.

After all, they are good sisters and best friends. If they talk at night, they must be in the same bed. Only in that way can both parties have a private night chat happily and quietly, so that they will not attract the selfless and like to raid the night patrol because of the loud voice, and will not attract more unnecessary punishments?

Then, she could take the opportunity to do something with her sister some of the last "dedication" plan that had been planning for a long time during the day, but she had never had the chance to achieve it. She almost thought that she would definitely have no chance today and would definitely die apart?

"stop!!"

"Heizi... If you dare to come over casually, I promise that you will definitely enjoy the kind of "super electrotherapy" care service of 100,000 volts for free later!!"

Mikoto Misaka is in a very unhappy mood now, and she feels very tired... So, she just wants to lie quietly alone, even if she doesn't do anything, even if she can't sleep at all. Anyway, she just doesn't want the bad kid who has bad intentions to come and disturb her at this time!

So, after hearing the rustling sound of getting up from the bed opposite behind her, after hearing the sound of the other person wearing slippers, and thinking about what the other person wants to do with her butt, she used her threatening to lower her tone, and hated someone behind her who was probably planning to stand up, and who was about to pounce on her bed, warning him sternly.

“Woo…”

"Sister, do you really hate Heizi so much? People... They just want to talk to you, but you can't sleep now..."

There was no way, the other party noticed his intention and found that the little Jiujiu in his heart seemed to be unable to achieve it. Heizi had to kick off the cotton slippers on his feet, retracted back to his bed, and then hugged the pillow in anger and looked at the pretty back of his sister in the darkness.

She obviously didn't dare to rush over after hearing the warning and crawled into the bed of her elder sister's bed and hugged the other person... because she knew that if she really dared to do that, what was waiting for her to greet her would definitely not be the warm embrace of her elder sister, but a terrible "electrotherapy" attack of one hundred thousand or million volts!

After all, the sour and refreshing "electrotherapy" process that can't survive or die cannot be killed. Anyone who has been electrocuted for the first time will definitely never be willing to try it again in his life!!

"Ha! You're right!"

"I really hate you now. If you dare to bake it, maybe I will use the ultra-electromagnetic gun to get it on for you?"

Mikoto Misaka did not give the Kuroko any face at all, and did not care about the pitiful look on the other person's face. She just turned over and glanced at the black shadow sitting on the bed opposite, then put her arms on her arms and stared at the ceiling with wide eyes.

After she started talking, she couldn't fall asleep easily now... So, it's not impossible to talk to the other party, but the other party would never come over and hide in the same bed with her as before. Especially today, she knew some of the other party's thoughts and plans, and was particularly angry!!

"uh-huh?"

"Sister, I'm not a brag. In the face to face, at such a short distance, I had just raised my hand and moved to another place in an instant. You couldn't even hit me by those lightning-speed lightning, let alone the 'ultra-electromagnetic cannon' with only three times the speed of sound!!"

Kuroko believes that the game coins ‘bombs’ that triple the speed of sound and are constantly accelerated by the electromagnetic field as they move may indeed pose a huge threat to others, but when they are prepared and face to face, the other party will definitely not hit her!

because,

She is a lv4 space movement ability. She can easily move elsewhere and escape in an instant with just one thought. The other party's "cannonball" has been flying and hitting for so long, so it will definitely not react faster than her thinking.

Therefore, if she was asked to defeat her sister, or compete with the other party for destructive power, she would definitely not have much confidence... However, if she just ran away and dealt with the other party, she would be confident that even the sister, who ranks third (or fourth) among all the eight lv5 superpowers in the Academy City, would never easily take down her lv4 Kuroko Shirai!

"oh?"

"Hizi, if we have a chance in the future, can we try it?"

Surprisingly, when he heard that the other party dared to underestimate his sister and lv5's superpowers, Mikoto Misaka couldn't help but snorted coldly from her mouth covered by the quilt.

That is, now she is in the dormitory. If she is elsewhere, based on her current mood, she would have to let some self-righteous arrogant maniac take a good look at the terrifying combat power that her sister, who is serious, can burst out?!

“Hmph…”

"Just try it, I'm not afraid of you!"

Shirai Kuroko, who has various arrogance attributes, has always lost no loss. She did not show any timidity to her sister’s proposal!

In fact, they can be said to have tried it today... Although the elder sister did not use all her strength at that time, she also did not use all her strength. Therefore, even if she did not have the confidence to defeat her sister with her lv4 space movement ability, it would definitely not be so easy for the other party to defeat her.

Of course, she must not be able to beat her sister if she fights life and death!

However, after all, my sister still likes her, and she also likes each other very much... Therefore, it is impossible for them to fight with their own abilities. Anyway, no one of them will do their best to attack each other. Regarding this, Heizi can be said to be very confident.

"But sister..."

"Why is your ultra-electromagnetic gun only three times the speed of sound, rather than faster? If it is faster, it will be more powerful, right?"

Heizi can actually be said to be quite clear about the power of his sister. It is the lv5 that can freely control one billion volt high voltage current and electromagnetic force, but it is one of the powerful abilities that are ranked first in the Academy City!

so,

After a month of knowing her, she felt a little puzzled and puzzled about why her sister could obviously make the "cannonballs" fly faster, but she deliberately suppressed the speed of the cannonballs, which made the cannonballs continue to accelerate during the flight.

"accelerate?!"

"It's not impossible, but Kuroko, you don't want me to have a good time, right?!"

After pausing, Mikoto Misaka did not explain why, but suddenly turned over and looked directly at the vague black shadow on the bed opposite that seemed to be squatting on the sheets.

"ah?"

"Sister, why do you say that?"

Obviously, Kuroko didn't understand why her sister asked herself so much. After all, her suggestions seemed to be bad. In her opinion, controlling more powerful current and electromagnetic forces to increase the "blowout" speed of the game coins to more than ten times the speed of sound is not an easy task for her sister?

Since that's the case, why do you have to deliberately suppress the speed and then you have to troubleshoot the shells before you continue to use current and electromagnetic force to control the shells from a longer distance and continuously accelerate the "plants" during flight. Wouldn't that be reversed, addicted to the whole and do something extra?

“…”

"Hizi, you should know a little about the principle of electromagnetic shells, right?"

The velocity of Misaka Mikoto's "electromagnetic shell" is proportional to the thrust of the shell, and the thrust of the shell is proportional to the square of the current. Therefore, it is not too difficult for her to maximize the velocity of the "arcine shell" and it is just to increase the strength of the current and magnetic field.

but……

"But Kuroko, you may not know..."

"Now the speed of my 'super electromagnetic cannon' when it is out of hand, the three times the speed of sound is already a certain threat to my fingers..."

"The information given to me by the school shows that when the shells accelerate to an ultra-high speed of six times the speed of sound per second, it will cause ablation of the track and ablation of the warhead! If the shells in the atmosphere are close to ten times the speed of sound, they will also undergo violent friction with the air and produce heat and discharge phenomena... And the ablation caused by ultra-high speed, ultra-high temperature and friction, and the cutting and wear of the track by the armature under high speed are all major problems that need to be solved in the research and development of orbital electromagnetic guns under modern technical conditions!"

"so……"

"If the 'cannon shell' leaves his hands too fast, it will not only seriously damage my fingers, but also release the energy of the magnetic field in an instant, causing a discharge that breaks through the air... Although I am not afraid of charge, at that time, it will instantly cut off millions of amperes of current and produce huge flames, explosions and powerful shock waves..."

"So after many verifications, without any protection, the triple speed of sound of the game coin's 'cannonball' is already a relatively safe critical point..."

"If it's fast, the high-speed game coins will rub against the air and produce ultra-high temperature and detonation effects. Even if my hands and fingers don't really touch the game coins when they are fired, they will be burned or destroyed by the high temperature burst out of the explosion... Of course, there are even more terrifying shock waves like explosions. They may easily tear all objects within a few meters like bombs, and they must also include my body!"

There is no doubt that Mikoto Misaka's fingers are definitely not as good as those electromagnetic railguns made of super alloys! And her own fourteen-year-old second-year student's body, in addition to having the super power of lv5, is just a little stronger than those ordinary people to some extent... Therefore, she herself must be unable to withstand the flames, explosions and the terrible shock waves that are powerful enough to tear steel apart!!

"So!"

"Unless it is in an ideal environment in a vacuum or with comprehensive protection, I will never easily change the speed of the 'cannonball'. Anyway, three times the speed of sound is almost the same. I would rather waste more power to slowly accelerate it on the flight route after it is removed, than to accelerate it directly to three times the speed of sound or higher by my side or in my hands!!"

"So, Heizi, what you said just now is completely untrue. I definitely won't be stupid. At the distance between my fingers, I accelerate the 'cannonball' to a terrible speed that I can't bear, and then bear the terrible consequences that I can't bear!!"
To be continued...
