A certain scientific Saten Ruiko

"Amazing power."

"but..."

The mechanical teeth-operating hand was slightly raised, and the concrete and other materials on the ground rose again, flying towards the gap where the stone monster was blasted. However, something unexpected happened again. He was originally controlling the materials on the ground in order to restore the stone monster. The original mechanical operator suddenly found that he could not control those concrete slabs.

No, it's not uncontrollable. If you look closely, you can see that there are very dense fine iron sands between the concrete slabs on the ground. It is precisely because of the presence of these iron sands that the concrete slabs and gravel are trapped.

Just when the mechanical operator's eyes showed horror, Misaka Mikoto's confident voice came clearly.

"It's because the parts are small enough to invade your insides." Misaka Mikoto put a confident smile on her face. She also took the time to secretly explain to Ruizi using the conversation line established between the two: "It's just as I thought. , the clone seems to be unable to control every vibrating grain of iron sand that turns into a sharp knife."

"Mikoto is so awesome."

Saten Ruiko sighed with emotion, is this the power of the strongest electric shock user? There must be at least hundreds of millions of iron sands, and every grain is vibrating. How much computing power is needed to support it? Or is there any simple algorithm?

"The next step is to cut it off inside you~"

Boom~boom! !

As Misaka Mikoto finished speaking, the stone giant, which had recovered somewhat, broke open again.

Apart from the initial surprise on Mechanical Teeth's face, her eyes were very calm as she seemed to have known about this situation for a long time. She turned her head and looked in the direction several kilometers away, raised her hand and waved, a huge high-voltage The gas tank flew directly to the city across the river.

"What? It's a high-pressure gas tank!?"

Misaka Mikoto, who had wanted to give the stone giant a final blow, was suddenly startled.

"This is not the empty can with only residue that was thrown at you just now, but a full one. What will happen if it falls in the city?"

"Mikoto, fire!!"

Ruizi pointed in the direction of the high-pressure gas tank and shouted.

"I know."

boom! !

The iron sand giant changed direction, and fired an ultra-long-range electromagnetic gun across the night sky, accurately passing through the high-pressure gas tank. The high temperature burned all the gas in an instant.

"Even if it is several kilometers away, the power is not reduced, so what will you do if there are several of them coming at the same time?"

As soon as the words fell, one, two, three, three huge high-pressure gas tanks flew into the air in a triangle shape.

"Three? Is she trying to drain my energy?"

"Let me do it."

Although she knew that even if she fired three more shots, Mikoto would still be in good condition, she couldn't really paddle that hard.

She pointed her hand at the three huge high-pressure gas tanks a few kilometers away, and with a look in her eyes, the three gas tanks were rushed into the sky by a strong air flow, and hit them at a distance of several hundred meters in the air. There was an explosion.

boom! Boom boom! !

The red light from the explosion briefly illuminated the night sky.

Snapped!

"It's done."

"Well done, Ichiko."

The two of them laughed and high-fived their hands, and then saw Misaka Mikoto looking at the mechanical teeth above the stone giant's head.

.........

Uiharu stood in front of the dormitory window and looked at the red light appearing in the distant sky with confusion.

"Strange, I don't remember there is a fireworks show tonight, what are they?"

.......

In dormitory 208, Heizi, who heard the explosion, turned his head and looked out the window.

"Isn't it... No, no, my sister may have done this." Denying the possibility of enemies fighting undeclared war, Heizi thought of what her sister had said and guessed that it was her sister who did it. She looked at it worriedly. time on your phone.

"But there is no contact with her..."

Thinking of what onee-sama said before leaving, Kuroko instantly hugged the killer bear doll and shouted.

"Ahhhh~~~Sister-sama~~Kuroko is so anxious~~~Uh-oh~Uh-oh~~~...."

Suddenly Heizi's voice stopped, she raised her head, her eyes turned into beady eyes, and there was a perverted smile on her lips.

"It's onee-sama's aura. Although I'm very anxious, Kuroko hasn't done this for a long time~"

Kuroko stared shyly at the killer bear doll that had the aura of his elder sister, and suddenly rushed forward to sniff it on Misaka Mikoto's bed.

"Hey, hey, hey...ahhhh~~~Sister-sama~~"

.......

"Huh~~"

Mikoto suddenly felt a cold feeling on her back and looked around hurriedly. She hadn't felt this way for a long time. What was it?

"Mikoto, what's wrong with you?"

"No...nothing. I just suddenly felt a chill down my spine. I always felt like something strange was staring at me."

"weird stuff?"

Ruizi tilted her head in confusion, as if she had thought of something, and she snickered in her heart. It was probably Kuroko who was having sex with Mikoto again, so that was the only way it could be.

"Huh? What is she doing?"

Mikoto's voice suddenly sounded. After the weird feeling disappeared, Misaka Mikoto just turned her eyes to the opposite side and saw the mechanical teeth, for some unknown reason, just standing there with her hair raised in a daze.

"It's enough. The iron sand blocks just used as bullets have covered the sky of Academy City. Although the density is far less than that of volcanic ash during volcanic eruptions, the iron sand dust will be swept into the stratosphere and fall on flying objects, no matter how hidden it is. Ingeniously, the interference of the iron sand and the hot wind generated by the explosion will disrupt the magnetism..."

Her mechanical eyes focused, and she began to search for the invisible spacecraft in the sky. Finally, her eyes settled on a certain direction, where she detected the source of the signal, and a successful smile appeared on her lips.

"found it."

.......

A motorcycle was moving quickly on the street. Under the white helmet, Ryoko Caochi looked through the goggles at the huge stone monster not far away, with a determined light shining in her eyes.

.......

"Probably looking for the spaceship that Sister Caoqi mentioned."

Saten Ruiko raised her head and looked at the sky. She had already discovered that thing. Although it was well hidden, as long as it was an object, it would squeeze the air away. In her perception, a huge aircraft was passing by in the sky. The thing must be the spaceship.

"Spaceship? Oh, by the way, the target of the clone was the spaceship from the beginning." Misaka Mikoto also looked at the sky. She was so absorbed in the fight just now that she almost forgot the other party's true purpose.

"Then what do we do next... ah? Where are the people?"

Misaka Mikoto withdrew her gaze and was about to say something about catching the clone. In the blink of an eye, the mechanical teeth that originally stood on top of the stone giant had long since disappeared.
